CESR's lead-byte +alignment shifts the payload, so e.g. `Verfer(bytes(0..32), Ed25519).qb64` is +`DAABAgMEBQYHCAkKCwwNDg8QERITFBUWFxgZGhscHR4f`, which differs from a naive `"D" + +base64url(bytes)`. Encoding and decoding route exclusively through +`KeriPublicKey::{to_qb64, parse}` (both cesride-backed). + +The transferability recorded from the code is load-bearing: it determines whether the +identifier may rotate (§7) and feeds the basic-derivation check (§3.3). + +### 3.2 Pre-rotation commitments + +A next-key commitment in `n[]` is the CESR-qualified Blake3-256 digest (`E…` qb64) of the +**CESR-qualified `qb64` form** of the next verkey — i.e. `Diger(ser=Verfer.qb64b)`, +**byte-identical to `keripy`** (ENFORCED — A.7). The commitment binds the curve and +transferability, not just the raw key bytes. `compute_next_commitment` takes a typed +`KeriPublicKey`, so the curve required to produce the qualified form always travels with +the key and length-based dispatch is impossible. + +### 3.3 Basic-derivation binding (ENFORCED — A.9) + +For a single-key inception, the controller prefix `i` must equal the qualified form of the +sole current key `k[0]` (the basic/self-certifying derivation). An inception whose `i` +does not match `k[0]` is rejected. + +### 3.4 Indexed signatures (PENDING — Epic B) + +Signatures attach as CESR indexed signatures. Dual-index emission (current-list index + +prior-list index, required to verify a rotation that *removes* a key) and the +code-directed attachment parser are **PENDING(B.1–B.4)**. Until then, asymmetric +key-count rotations (prior next-count ≠ new key-count) are rejected rather than verified +with an ambiguous single index. + +--- + +## 4. Thresholds (ENFORCED — A.4) + +`kt`/`nt`/`bt` are either a hex integer (`m`-of-`n`) or a fractional-weight list. + +- A threshold is validated for **satisfiability** against its list length at ingest: a + weighted `nt` can no longer be silently collapsed to `1`-of-`n` (closes F-15). +- Empty backer set requires `bt == 0`. +- Pre-rotation satisfaction is evaluated over the **typed** prior `nt`: each revealed + next-key index counts toward the threshold, and the typed predicate decides — not a + `simple_value().unwrap_or(1)` collapse. + +--- + +## 5. Configuration traits (`c[]`) + +| Code | Meaning | Status | +|------|---------|--------| +| `EO` | Establishment-Only — KEL may contain only establishment events; `ixn` prohibited. | ENFORCED | +| `DND` | Do-Not-Delegate — identifier may not act as a delegator. | ENFORCED (rejected in `validate_delegation`). | +| `RB` | Registrar Backers — `b[]` names registrar-backer AIDs. | role-flip ENFORCED (A.13) | +| `NRB` | No Registrar Backers — backers are witnesses. | role-flip ENFORCED (A.13) | + +### 5.1 Registrar-backer role flips (ENFORCED — A.13) + +`RB` and `NRB` carry different backer-list semantics. A rotation whose `c[]` flips the +role (`RB`↔`NRB`) while any prior backer survives is **rejected** — a role flip MUST +rebuild `b[]` (cut every prior backer via `br`). An empty `c[]` inherits the role and +cannot flip. + +The non-standard `Delegate-Is-Delegator` (`DID`) trait was **removed** (A.13): a config trait +that waives the delegation seal is a delegation-authorization bypass, and it was never consumed +by `validate_delegation` (which fail-closes on the anchoring seal regardless). Full +registrar-backer `bt` accounting is deferred to a tracked issue (Epic H.5). + +--- + +## 6. Seals (`a[]`) (ENFORCED — A.8) + +The canonical anchor seal is an **event-location seal** with fields `{i, s, p, t, d}` +(`SealEvent`). Delegated-event validation searches the delegator's KEL for a +location/digest seal matching the delegated event's `i`/`s`/`d`. + +Extended seal shapes (`MerkleRoot`, `RegistrarBacker`) are gated behind the +`seal-extensions` Cargo feature and are **not** part of the default wire surface. The +default deserializer rejects unknown seal shapes. + +--- + +## 7. Transferability and abandonment (ENFORCED — A.12) + +- A non-transferable inception (empty `n[]`, non-transferable verkey code) is + **non-transferable**, *not* abandoned. It simply cannot rotate or emit `ixn`. +- **Abandonment** is a post-inception state reached only by a rotation to an empty next + commitment. `is_abandoned` is `false` at inception regardless of transferability. + +This distinction matters: a verifier must treat "this identity was born non-rotating" and +"this identity rotated itself into the ground" differently. + +--- + +## 8. Witness receipts (`rct`) (ENFORCED — D.4) + +A receipt body is `{v, t, d, i, s}` where: + +- `t` is the constant `"rct"` (a typed tag — a receipt can never carry a forged `t` such + as `"icp"`; non-`rct` values fail to parse). +- `d` is the SAID of the **referenced key event**, not the receipt's own SAID. +- Signatures are **externalized** (not in the body); a `SignedReceipt` pairs the body with + its detached witness signature. + +--- + +## 9.

The AID is what `b[]` designates, what KAWA dedupes quorum + by, and what a collected receipt's signature is verified against. (D.1) + +3. **Delegation witnesses = root-inherited.** A device's delegated `dip`/`drt` + carries `b=[]`, `bt=0`; trust flows through the **receipted root `ixn`** that + anchors the delegation. Devices do not run their own witnesses in this epic. + +4. **Verifier policy = warn-default, fail-closed opt-in.** A verifier cannot + trust the signer's self-declared `WitnessPolicy` (that lives in the signer's + config). Verification has its **own** policy: default **Warn** (an under-quorum + signer KEL verifies with a non-fatal warning, preserving the trust-on-first- + sight caveat during rollout); `--require-witnesses` opts into **fail-closed** + (under-quorum is a typed verification failure). (D.7) + +5. **Receipt provenance = stored witness AID.** The wire `rct` body stays + spec-shaped `[v,t,d,i,s]` (its `i` is the *controller* AID). The verifying + **witness AID** travels alongside the receipt out-of-band, as + `StoredReceipt { signed, witness }`. Collection verifies each receipt's + signature against the pinned witness key and drops forged / foreign / + wrong-SAID receipts before storage or quorum. (D.2) + +6. **Annex-A superseding recovery = deferred.** Epic D *detects and refuses* on + irreconcilable duplicity (first-seen + flag/refuse).

(E.3–E.5) + +2. **Reciprocal source seal = bilateral binding.** `dip`/`drt` carry the delegate-side + `-G` `SealSourceCouple` (snu+dig back-reference to the anchoring event), and + `validate_delegation` enforces **both** directions — the delegator-side + `Seal::KeyEvent` *and* the delegate-side back-reference. This is required for honest + keripy 1.3.4 byte-interop (keripy emits `-G`). The seal is an attachment added after + anchoring (cooperative double-anchor): it never changes the event SAID or the signed + bytes. (E.1) + +3. **Scope/expiry = delegator-anchored scope seal.** Authority comes from the party + that controls the delegator key: the scope (capabilities + optional expiry) rides a + `Seal::Digest` marker in the **delegator's** own `ixn`, never in the delegate's KEL + (a compromised agent must not widen its own scope). Expiry is **verifier-enforced** + via an injected `now`. The capability-subset rule (a delegate may only narrow) is + reused from the deleted bearer model. ACDC/TEL credentials are the principled + upgrade (Epic F). *Interim fallback (unused):* a delegator-signed attestation, never + agent-self-asserted. (E.7) + +4. **Org threshold = `kt=1` now, `kt≥2` deferred.** `author_root_anchor_ixn` is + single-author, so an org delegator must be single-signature. A `kt≥2` org delegation + is rejected with a typed `OrgError::OrgThresholdDelegationUnsupported`; multi-sig org + anchoring is deferred (see Deferrals). `kt=1` is the documented pre-launch baseline. (E.8) + +5. **Org membership = `dip` delegated by the org AID, fail-closed.** An org member is a + delegated identifier of the **org** AID (not an attestation `delegated_by`); the org + anchors the member's `dip` and a role/capability scope seal. Authority is read + **KEL-authoritative and fail-closed**: a member revoked on the org KEL is + unauthorized **even if a stale attestation is present** — readers never OR-fallback + to an attestation. Admin authority = holding the org signing key (the key that + anchors the org KEL); the legacy attestation `manage_members` admin lookup is gone + from add/remove. The member's role rides the scope seal as a `role:{role}` marker. (E.8) + +6. **Legacy bearer-token model = deleted.** Pre-launch, zero users — the UUID/bearer + model and `auths-api /v1/agents` were removed rather than migrated.

Capabilities and roles become +verifiable credentials — **ACDC** (Authentic Chained Data Containers) — with +KERI-native per-credential revocation — **TEL** (Transaction Event Log) — anchored +to the issuer's KEL. This is the credential-grade upgrade to Epic E's *advisory*, +delegator-anchored scope seal: per-capability revocation (revoke one credential +without rotating keys or revoking the identity), third-party verifiability, and a +holder-bound presentation model. It is **not** full vLEI/IPEX interop. + +## Context + +Epic F is optional to the core thesis — device-bound commit signing, provable by KEL +replay, needs none of it. It was nonetheless built **first-class, not as a deferred +afterthought**: when we ship credential-grade authorization it must be *robust* — +minimal trust surface, maximal trust guarantees. The non-negotiable v1 properties: +credentials are **holder-bound, never bearer**; revocation is **witnessed** +(transitively, via the KEL anchor) and **freshness-checked**, never +trust-on-first-sight-silently; both curves (**P-256 default + Ed25519**) are exercised +from day one; and the SAID layout is forward-compatible for `e` so edges are additive. +We defer *features* (full IPEX, edge/rule content, OIDC, escrow). We do **not** defer +security properties. + +Exhaustive search at the start of Epic F found no ACDC/TEL/credential/registry code — +only forward-reference comments — but the exact KERI primitives needed already existed +and were keripy-1.3.4 byte-aligned (SAID-ification, CESR encoders, TEL→KEL anchoring as +a `Seal::KeyEvent` in an `ixn`, signing-time key recovery, KEL-position revocation +ordering, the policy-context bridge template). Epic F built the credential layer **on** +that substrate. + +The decisions below were surfaced during gap analysis and are recorded here as the +load-bearing scoping and authority choices. + +## Decisions + +1. **D1 — ACDC is ADDITIVE, not a commit-time replacement.** Epic E's `agentscope:` + seal + `Auths-Scope` trailer remain the *commit-time signing* fast path. ACDC subsumes + the **attestation** authority fields (`capabilities`/`role`) — the migration target the + roadmap names. Commit verification is **not** rewritten in v1; an `Auths-Credential` + trailer that makes ACDC the commit-time authority is the deferred integration point + (see Deferrals). This keeps blast radius sane and matches "not required for the core + thesis." + +2. **D2 — Backerless (`NB`) registry, with witness-enforced revocation.** Event types + `vcp` (registry inception, once per issuer), `iss` (issuance), `rev` (revocation). + Never `bis`/`brv`/`vrt`/TEL backers — a parallel trust system is the wrong mechanism. + **Robustness comes from witnessing the KEL anchor, not from TEL backers:** every + `vcp`/`iss`/`rev` is anchored by a `Seal::KeyEvent` in the issuer's KEL `ixn`, which + post-Epic-D is witness-receipted. The F.9 pre-flight finding (proven by test) is that + the Epic-D KEL gate quorum-gates *establishment* events only — "ixn never gates" — so + the verifier (F.5) itself quorum-checks the **lifecycle anchoring ixns** + (`vcp`/`iss`/`rev`) via the KAWA `WitnessAgreement` algorithm (Option A). See the + composed witness claim below. + +3. **D3 — Holder-bound minimal ACDC `{v,d,i,ri,s,a}` (NOT a bearer token).** The subject + `a.i` is a **KERI AID** (D5 guarantees the issuee has a KEL); authority is honored only + when the presenter proves current control of that AID. Possession of the ACDC alone + grants nothing — this avoids the bearer-token red flag. For commit signing this is + automatic (the signer's KEL). For third-party presentation, v1 requires a + **presentation signature** by the subject's signing-time key over + `(credential-SAID, audience, nonce)` (F.8) — a thin precursor to IPEX, not full IPEX. + One pinned JSON-Schema-2020-12 capability schema; the schema SAID is embedded and + immutable. + +4. **D4 — Fail-closed + revocation-freshness (v1).** A TEL event whose KEL anchor is not + present locally is rejected, never accepted (no escrow of out-of-order events). **Plus: + freshness is a first-class verdict — owned by the SDK resolution layer, not the pure + verifier.** The pure verifier (F.5) cannot resolve a KEL tip or judge staleness (no + network, no clock of its own); it checks what it is handed and reports the **"as-of" + position** of that input plus the witness-quorum status. The SDK `credentials::verify` + (F.4) resolves the issuer KEL/TEL/receipts to the witnessed tip, then judges freshness: + "not revoked" means no `rev` anchored at or before the resolved tip, and an + unresolvable/stale tip yields `StaleOrUnresolvable` (fail-closed), never a silent valid. + +5. **D5 — Separate issuance step.** Delegate first (`agents::add` / `org::add_member` → + issuee gets a KEL), THEN `credentials::issue(issuer, issuee_did, caps, …)`; hard-fail if + the issuee prefix has no KEL. The `vcp` registry is lazily incepted on first issuance + per issuer. + +6. **D6 — Revocation is per-CREDENTIAL** (TEL `rev`), distinct from the coarse + `agents::revoke` (whole delegate). This per-capability granularity is what ACDC buys. + +7. **D7 — SAID protocol tag parameterized.** `compute_said` previously hardcoded + `KERI10JSON`; F.1 parameterized the version/protocol tag (a `Protocol` enum) so ACDC + emits `ACDC10JSON…` for keripy interop. The 17-char version-string layout and **all KEL + SAIDs are unchanged**. + +8. **D8 — Dual-curve is a v1 acceptance gate, not a follow-up.** The agents suite was + once Ed25519-only and hid a P-256 break for an entire epic. Epic F does not repeat that: + every credential/TEL signature and every embedded key is **curve-tagged in-band** (CESR + prefix / multicodec / explicit field — never dispatch on byte length), and the keripy + fixtures **and** unit tests run issue → verify → revoke for **both P-256 (default) and + Ed25519**. `check-curve-agnostic` stays at 0 violations. + +### RegistryBackend freeze-touch resolution (F.3) + +TEL storage required touching the **frozen** `RegistryBackend` trait. The resolution was +to **extend** it — `append_tel_event` / `visit_tel_events` / `store_credential`, plus an +`AtomicWriteOp::AppendTelEvent` and a `refs/.../tel///` layout. The +documented atomicity justification: the ACDC blob, the TEL event, and the KEL anchoring +`ixn` must land in **one commit**, mirroring the existing attestation write-batch +exception. `anchor_tel_event` reuses the staged single-author `ixn` path +(`author_root_anchor_ixn` was refactored into a `stage_root_anchor_ixn`), and +`ensure_registry` lazily incepts an idempotent backerless `vcp` per issuer. A `kt≥2` +issuer is rejected with a typed error (single-author anchoring only — same limit as Epic +E org delegation). + +### `agentscope:` seal vs ACDC capability precedence (F.6) + +There are two on-chain encodings of a capability/role grant, serving different decision +grades, reconciled by a documented `CapsSource` precedence rule +(`auths-id/src/policy/mod.rs`): + +- **`agentscope:` scope seal** — the Epic-E `Seal::Digest` anchored in the delegator's + `ixn`. It is **commit-time advisory**: the offline fast path a verifier reads straight + off the KEL without a live presentation. It is the low-latency convenience source, not + an authority of record. +- **ACDC credential** — the **authoritative** caps/role source for credential-grade + decisions. Authority derived from it is honored only through a **holder-verified + presentation** (F.8) at the policy seam (`context_from_credential`). + +**Anti-divergence rule:** the same grant MUST NOT be authored into both encodings with +diverging caps/role. When both exist for one grant, `CapsSource::governing` selects the +ACDC — the credential governs the credential-grade decision; the `agentscope:` seal +remains valid only as the advisory commit-time fast path. + +## The composed witness claim (F.9) — canonical assurance + +This is the precise, honest statement of what `Valid` means under each witness policy. +It is quoted here verbatim as the canonical assurance: + +> Under `RequireWitnesses`, a credential is `Valid` only if (a) the issuer's KEL +> establishment events reached quorum [Epic D], (b) its `vcp` *and* `iss` anchoring ixns +> reached quorum [F.5/A], and (c) no quorum-reaching `rev` anchor exists at/before the +> presentation's KEL position. Under `Warn` (default), under-quorum is a warning (TOFS) +> and `detect_duplicity` still catches revocation-hiding-via-fork. + +## What shipped (NOT deferred) + +These v1 properties **shipped** in Epic F and must not be mistaken for future work: + +- **Holder-binding (F.8)** — credential-derived authority is honored only on proof of + current control of the subject AID by KEL replay plus a fresh presentation signature + over `(credential-SAID, audience, nonce)`. The interactive challenge-response path + (verifier-issued single-use nonce) is the v1 default; a non-interactive + `(audience, purpose, short-TTL)` path exists with a documented within-TTL residual. + `PresentationVerdict` distinguishes `HolderNotCurrentKey` / `WrongAudience` / + `NonceMismatchOrConsumed` / `Expired` / `SubjectKelInvalid` / `CredentialNotValid`. +- **Lifecycle witness-quorum (F.5/F.9)** — the verifier enforces witness quorum over the + `vcp`/`iss`/`rev` anchoring ixns (not just establishment events) via KAWA, per the + composed claim above. `WitnessQuorumNotMet` names which lifecycle anchor missed. +- **Revocation freshness (F.4)** — the SDK resolves to the witnessed tip and owns the + `StaleOrUnresolvable` fail-closed verdict; absence-of-`rev` is never silently treated as + valid. + +## Threat model + +Each attack is paired with its mitigation. The single residual is stated honestly. + +- **Revocation-hiding / equivocation** → the `rev` event is **KEL-anchored**; hiding it + requires forking the issuer's KEL. The anchoring ixns are **witnessed** under the F.5/F.9 + lifecycle witness-quorum (composed claim, depends on Epic D), and `detect_duplicity` + flags the fork in both witness modes. +- **Credential theft / replay** → **holder-binding** (F.8): authority needs proof of + *current* subject-key control via challenge-response (verifier-issued single-use nonce), + not mere possession. A stolen ACDC blob grants nothing without the subject's current + signing key. +- **Issuer key compromise + rotation** → the issuer signs with its **signing-time key**; + verification recovers the key in force at the `iss` anchor position, so a `iss` forged + with a post-rotation key does **not** verify. Recovery = rotate the issuer key and + `rev` the affected credentials (or use the `vcp`-level kill-switch). Credentials issued + before the compromise remain valid until explicitly revoked. +- **Registry / TEL fork** → `detect_duplicity` on the issuer KEL/TEL surfaces the + divergence; the no-witness stance is **first-valid-seen + refuse** (verdict + `IssuerKelDuplicitous`), never silent acceptance of a forked branch. +- **Downgrade / staleness** → the SDK freshness verdict `StaleOrUnresolvable` (F.4) plus + the witness policy: an unresolvable/stale tip **fails closed**; the verifier never + treats absence-of-`rev` against a stale view as "not revoked." +- **Revocation latency under `RequireWitnesses` (residual — stated honestly)** → a `rev` + only revokes once it reaches quorum (claim (c) above), so the window between authoring a + `rev` and its receipts reaching quorum leaves the credential `Valid` to a + `RequireWitnesses` verifier. The hiding of that `rev` is still fork-detectable via + `detect_duplicity`, and under `Warn` (default) a seen `rev` revokes immediately. This is + the deliberate trade-off of witnessed fail-closed revocation; it is not a silent gap. +- **Schema substitution** → the capability schema SAID is **pinned and embedded**; an + unknown or substituted schema SAID is rejected (`SchemaInvalid`). + +## Epic-D dependency + +The lifecycle witness-quorum (the witnessing of the `vcp`/`iss`/`rev` anchoring ixns, per +the composed claim) requires **Epic D** landed for its fail-closed mode. Until then, the +default `Warn` mode is honest **trust-on-first-sight** — the same caveat as the commit +path — with under-quorum surfaced as a non-fatal warning and `detect_duplicity` still +catching revocation-hiding-via-fork. + +## Forward-compatibility honesty (no over-claim) + +The most-compact SAID makes a future **top-level `e`** (edges) block additive: a v1 +credential SAID is unchanged for present fields, so edges can be layered without a +breaking change. **Selective / graduated disclosure (`u`/`A`) is NOT additive** — `u` +lives inside the attributes block and changes `a.d` and `d`, so **selective disclosure is +a SAID-breaking v2** (a new schema/version). We claim forward-compatibility only for `e`, +never for SD. + +## Consequences (assurance, stated precisely) + +- A capability is a first-class, holder-bound, KEL-anchored credential: a third party + verifies it purely by replay (SAID + embedded schema + issuer signing-time key + TEL + status by KEL position + witness-quorum) and honors its authority only against a + holder-verified presentation. No bearer token anywhere on the path. +- Per-credential revocation is independent of key rotation and identity revocation. +- Attestation-borne `capabilities` + `role` are no longer the authority of record — every + reader was migrated off them (F.10) and the write path that stamped them was removed + (F.11). OIDC + `delegated_by` remain on the attestation (deferred). +- Under `RequireWitnesses` the assurance is exactly the composed claim above, with the + documented revocation-latency residual. + +## Deferrals (tracked) + +Each item below is genuinely out of Epic F v1 scope and has a tracking GitHub issue on +`auths-dev/auths` (each back-referencing this ADR). Holder-binding, lifecycle +witness-quorum, and freshness are **NOT** deferred — they shipped (see "What shipped"). + +1. **Backed registries (`bis`/`brv`/`vrt`/TEL backers)** — + [#221](https://github.com/auths-dev/auths/issues/221). v1 is backerless `NB`; trust + derives from the witnessed KEL anchor, not TEL backers. +2. **ACDC edge (`e`) + rule (`r`) content** — + [#222](https://github.com/auths-dev/auths/issues/222).

F.10/F.11 migrated `capabilities` + + `role` only; OIDC binding stays on the attestation for v1. +8. **Dynamic / `oneOf` schema registry** — + [#228](https://github.com/auths-dev/auths/issues/228). v1 pins one embedded + JSON-Schema-2020-12 capability schema. +9. **`delegated_by` → ACDC edge** — + [#229](https://github.com/auths-dev/auths/issues/229). `delegated_by` stays on the + attestation; modeling delegation provenance as an ACDC edge depends on (2). + +Already filed from F.10: + +10. **ACDC-sourced capability gate for artifact/device verification** — + [#220](https://github.com/auths-dev/auths/issues/220).

But KERI **pre-rotation** requires every key in a rotation's new `k[]` to +be the revealed pre-image of a prior `n[]` commitment — and **a single device holds only its own +pre-committed next key**. It has the *digests* of the other devices' next keys (from prior `n[]`), never +the pre-images. Therefore: + +> **One device cannot author a keripy-valid `rot` that rotates a multi-device `k[]`.** It cannot produce +> the revealed next keys of the other controllers. + +The current `rotate_registry_identity_multi` "works" only because it decrypts **every** survivor's next +key from the *local* keychain (`rotate.rs` survivor loop) — i.e. it assumes **one host holds all +controllers' keys**. That is single-host-many-keys, **not** device-bound multi-device. The dual-index +removal fixtures were keripy-validated under exactly that one-host assumption (one test held `s0..s4`). + +### The two coherent models + +**Model D — Delegation (recommended).** Each device is a KERI **delegated identifier** (`dip`) of the +root identity. The root **anchors** a delegation seal (`ixn`) authorizing a device; removal anchors a +revocation. Each device runs its own KEL and rotates independently (`drt`). +- **keripy-valid** — delegated AIDs are standard KERI. +- **True device-bound** — each device holds only its own key + KEL. +- **Single-author set changes** — device add/remove is an `ixn` anchor signed by the root's *current* + key (no pre-rotation reveal, no other device's private key). Simpler than a shrink `rot`. +- **Verification** — a commit signer's device KEL chains to a root-anchored delegation → authorized. +- **Unifies with agents** — Epic E models agents as delegated identifiers too: devices and agents + become one `dip`/`drt` concept. +- **Reuses what's built** — `dip`/`drt` events, device KELs, the dual-index CESR primitive, the + verification core. The shared-`k[]` controller layer (`shared_kel.rs`) is retired for multi-device. +- **Tradeoff** — introduces a root/primary asymmetry (the root key anchors delegations). For developer + identity this is desirable (a clear root of trust); root-key loss is a recovery concern, not a + per-operation one, since set changes are `ixn` anchors the delegates don't need to co-sign. + +**Model S — Per-device-custody shared KEL.** Keep `k[]` = device verkeys.

Current Status + +We have shipped Stage 1 of the design ladder: every device runs its own KERI +KEL, and the user's identity is a shared KEL whose controllers are those +device DIDs. + +### What's working + +- **Per-device KEL.** Each device has a stable `did:keri:` prefix that + survives its own key rotations. Defined in + `crates/auths-id/src/keri/device_kel.rs`, stored under + `refs/auths/device-kel/{prefix}/*`. +- **Shared identity KEL.** Multi-controller KEL whose `k` list is the user's + device DIDs. Defined in `crates/auths-id/src/keri/shared_kel.rs`, stored + under `refs/auths/shared-kel/{prefix}/*`. +- **Pair flow.** Mutual inception verification + `rot` on the shared KEL + adding the new device as a controller. +- **Local rotation.** A device rotates its own keys via a local `rot` on its + own device KEL — no session, no ceremony. Pre-rotation reveal is committed + in the same event. +- **Stolen-laptop recovery (swap).** A surviving controller signs a `rot` on + the shared KEL that drops the lost device's DID and adds a new one in a + single event. Wired up to `auths device pair --recover`. Implemented via + `rot_swap_controller` in `shared_kel.rs:256-265`. +- **Duplicity detector.** `auths_verifier::duplicity::detect_duplicity` + read-only scan flags diverging shared-KEL forks, with the resolution path + surfaced in `auths status` and iOS `IdentityView`. + +### Risks we are shipping with + +These are accepted at this phase and tracked to the epic that closes them. + +#### Duplicity under `kt=1` → closed by Epic 2 + +The shared identity KEL runs with a threshold of one — any single controller +can sign a rotation. With no witness infrastructure, two controllers can +each author a valid `rot` at the same sequence number independently, +producing a permanently diverging KEL. Mitigation: `detect_duplicity` +reports `DuplicityReport::Diverging` with conflicting event SAIDs; users +resolve by running `auths device remove ` on the +trusted device. The detector is fail-open — duplicitous shared KELs do not +invalidate signatures whose signers are current controllers on their own +device KELs. + +#### No witnesses → addressed by Epic 3 (≡ roadmap "Epic D") + +> "Epic 3" here and "Epic D" in `keri-only-roadmap.md` are the **same** witnessing +> epic. See `ADRs/006-witness-receipting-and-duplicity.md` for the decisions. + +Historically verifiers trusted "first valid event seen locally" — no source of +truth for ordering. Epic D wires witness receipting into the trust path; the +assurance story is now graded, and it is worth stating **precisely what +witnessing removes and what it does not**: + +- **`bt=0` (no witnesses) = trust-on-first-sight.** This remains the baseline for + identities that designate no backers. `detect_duplicity` still flags same-`(i,s)` + divergence locally and across sources (local vs remote), and the resolver now + *refuses* a cross-source fork rather than silently picking a side. +- **`N=1` witness tolerates `F=0`** faulty witnesses and **does not** stop + controller+witness collusion: a single operator can still equivocate with a + colluding controller. One witness buys accountability against a passive/absent + observer, not against collusion. +- **`N=3, bt=2`** is the smallest real BFT-flavored config: it tolerates one bad + or unavailable witness. A forged, duplicate-witness, or wrong-SAID receipt does + not count toward quorum. +- **No global ordering / consensus.** KAWA gives *accountability* (M-of-N distinct + witnesses attested this establishment event), not a chain or network-wide + ordering. A witness-receipted key-state is **never** authoritative over a + resolvable KEL (replay the log), and a delegated-device witnessed KSN still + cannot prove non-revocation (a root-KEL `ixn` fact). + +Blast radius remains bounded: each controller device replicates the full shared +KEL locally, so verifiers are limited to controllers' devices rather than +arbitrary third parties. + +**Out of scope (deferred):** Annex-A superseding recovery +(rotation-supersedes-interaction; toad-vs-first-seen tiebreak) — Epic D *detects +and refuses*, it does not *auto-recover*. Tracked in ADR 006. + +#### Pure removal blocked → closed by Epic 1 + +`rot_remove_controller` returns `RemovalNotYetSupported`. Removal that +shrinks `k` (rather than swap-in-place via `rot_swap_controller`) requires +CESR indexed-signature support that distinguishes "prior-next slot N +revealed" from "new-current slot M fresh." Until then, recovery uses swap +exclusively. See `shared_kel.rs:120-134` and `keri_compliance.md` finding +F-19. + +#### Pair-URI size bound → revisited by Epic 2 + +The pairing URI carries the initiator's device-KEL inception event +(base64url-encoded JSON) in-band. `SubmitResponseRequest::validate()` +enforces `SHARED_KEL_INCEPTION_EVENT_MAX_BYTES = 1024`. Single-sig P-256 +inceptions weigh ~300 bytes encoded, so the cap reserves headroom while +refusing to ship anything that would overflow QR capacity. Multi-sig +inceptions (Epic 2) will exceed this cap and require a different +out-of-band exchange medium (NFC, Bluetooth, file handoff). + +#### KERI wire-format divergence → closed by Epic 4 + +Several deviations from ToIP KERI v1.1 ship today (catalogued in +`docs/plans/keri_compliance.md`): an in-body `dt` field that enters the +SAID, a signing path that clears `d`/`i` after computing `v`, a mobile FFI +duplicate of `IcpEvent` with an in-body `x` signature, and use of `1AAI` +(non-transferable) as the P-256 verkey code for transferable identities. +Internally consistent; cross-implementation interop with KERIpy / KERIox / +Signify is currently broken. Pre-launch posture means we ship and fix. + +#### Trailer-format break (one-shot, complete) + +Commits signed before this phase carry a single `Auths-Signer: did:key:z…` +trailer. Verifiers now read two `did:keri:` trailers written by `auths sign`: +`Auths-Id` (the root identity) and `Auths-Device` (the signing device). Trust +is decided by KEL replay against the `.auths/roots` pin — there is no +`allowed_signers` allowlist. Pre-launch zero-user migration: dev machines +that signed under the old format must `rm -rf ~/.auths && auths init` +followed by re-signing. No code epic — this is a status acknowledgement, +not a future task. Authoritative migration note in +`docs/plans/toward_keri_witnesses.md`. + +--- + +## 2. Vision + +The end state is a multi-device KERI identity that survives realistic +attacker models and interoperates with the broader KERI ecosystem. + +- **Co-signed rotations** (`kt ≥ m` of `n`). No single device can solo-rotate + the identity; loss of one device cannot lock a user out, and compromise of + one device cannot rewrite the controller set. +- **Network-wide event ordering.** Witness infrastructure (KERI-native, + Rekor-style anchor, or OOBI-discovered) gives verifiers a consistent view + of the authoritative KEL state independent of which controller they last + synced with. +- **True device removal.** Surviving controllers can shrink the controller + set without needing to add a replacement in the same event. Backed by + CESR dual-index signatures. +- **Heterogeneous-curve controller sets.** A user can have a P-256 SE-backed + iPhone and an Ed25519-backed Linux laptop as co-controllers of the same + shared identity, with attachments that parse cleanly across curves. +- **Cross-impl interop.** Auths-produced KELs round-trip with KERIpy, + KERIox, Signify, and KERIA. Auths-consumed KELs from those impls verify + here without translation. +- **External federation.** `did:keri:You` is publishable to third-party + relying parties (sigstore-style transparency log, KERI registry, or + domain-bound discovery). Out of scope for this document; gated on + witnesses and spec compliance landing first. + +--- + +## 3. Roadmap: Epics + +Epics are sequenced by dependency, not by calendar. Each epic names the +risk(s) it closes from §1 and its prerequisites. + +### Epic 1 — Dual-index CESR signatures, true removal + +**Closes:** "Pure removal blocked" risk; unblocks Epic 2. +**Prerequisites:** None — can start today. +**Why first:** Multi-sig rotations under `kt ≥ 2` (Epic 2) need the same +dual-index machinery to bind each signature to both a new-key index and a +prior-commitment index. Building it once for removal and reusing it for +multi-sig saves a re-design. + +Tasks: + +- **1.1 Extend `IndexedSignature`.** Add `prior_index: Option` to + `crates/auths-keri/src/events.rs:1049-1056`. Single-index sigs + (icp / ixn) use `None`; rotation sigs carry `Some(j)` binding to prior + `n[j]`. +- **1.2 Dual-index CESR codec emission.** Update `serialize_attachment` in + `events.rs:1106-1135` to choose `indexer::Codex::Ed25519_Big` (or curve + equivalent) when `prior_index.is_some()`. Match on the parsing side in + `parse_attachment`. +- **1.3 Code-directed attachment parser.** Replace the fixed-width + 88-char-per-siger assumption in `parse_attachment` (`events.rs:1139-1185`) + with code-directed dispatch via cesride's width table. Required for + mixed-curve controller sets (Vision item 4). +- **1.4 True-remove rotation validator.** In + `crates/auths-id/src/keri/shared_kel.rs`, replace `RemovalNotYetSupported` + with the actual implementation. Validator must verify each prior `n[j]` + has a matching reveal among new keys, indexed by the dual-index + attachment. Keep `rot_swap_controller` as the convenience path for the + common recovery case. +- **1.5 CLI surface.** `auths device remove ` signs a + shrink-`k` rotation. Update `auths status` and iOS `DevicesView` removal + action. +- **1.6 Spec-compliance fix F-15.** While here, fix the weighted-threshold + pre-rotation check in `validate_rotation` (`validate.rs:438-454`): use + `Threshold::is_satisfied` with explicit `verified_commitment_indices` + instead of `simple_value().unwrap_or(1)`. The current code silently + reduces weighted `nt` to threshold 1 — same root cause as the dual-index + gap. + +Verification: a shared KEL with three controllers can be rotated to two via +a pure removal; the resulting KEL replays cleanly under +`validate_kel_with_lookup`; KERIpy round-trips the resulting events. + +### Epic 2 — Threshold upgrade (`kt ≥ m` of `n`) + +**Closes:** "Duplicity under `kt=1`" risk. +**Prerequisites:** Epic 1 (dual-index sigs). +**Why second:** Duplicity is the single largest unmitigated security gap +under the current model. m-of-n co-signing kills the race — two controllers +cannot independently produce diverging valid rotations because no single +signature satisfies threshold. + +Tasks: + +- **2.1 Multi-sig signing protocol.** Add a partial-signature collection + step to the pair / rotate flows: one controller drafts the event, peers + sign it, the originator assembles the dual-index attachment when threshold + is met. New protocol message types in + `crates/auths-pairing-protocol/src/types.rs`. +- **2.2 Threshold-aware validators.** Audit every `simple_value().unwrap_or(…)` + call site in `auths-keri/src/validate.rs` (compliance findings F-04, F-13, + F-15, F-31). Replace with typed threshold satisfaction checks. Includes + full inception-time `kt` vs `|k|` validation and `bt` vs `|b|` validation. +- **2.3 UX for partial signing.** iOS: a "co-sign rotation" notification + flow. CLI: `auths rotate --request ` and + `auths rotate --sign `. Both surfaces show the threshold + progress (1 of 2 sigs collected, etc.). +- **2.4 Recovery semantics under `kt ≥ 2`.** Define and implement: what + happens when `m` controllers are available but `m - 1` is required for + recovery rotation? Current Stage 1 swap relies on solo signing; under + multi-sig, recovery requires either `m` surviving controllers or a + pre-staged recovery quorum. Document trade-off in + `essays/design/multi_device.md`. +- **2.5 Pair-URI medium upgrade.** Multi-sig inception events exceed the + 1024-byte QR cap. Add a fallback handshake — file handoff + QR pointer is + the simplest; NFC and Bluetooth are alternatives. Drop the size cap + enforcement once the fallback is wired. +- **2.6 Migration of existing kt=1 KELs.** Decide and implement the upgrade + rotation: a `kt=1` shared KEL signs one final `rot` raising `kt` to the + new threshold. No lock-out risk because kt=1 still allows the upgrade + itself. + +Verification: a 2-of-3 shared KEL rejects a solo rotation from any single +controller; accepts a co-signed rotation from any two; survives loss of any +one device via co-signed recovery from the remaining two. + +### Epic 3 — Witness infrastructure + +**Closes:** "No witnesses" risk. +**Prerequisites:** Epic 2 (multi-sig is the foundation; witnesses ratify +threshold-met events). +**Why third:** Without multi-sig, witness receipts only attest that "we +saw the kt=1 controller's solo rotation first" — they reduce duplicity but +don't eliminate the attacker model where one compromised device wins the +race. Witnesses are most useful when stacked on top of co-signing. + +Sub-decisions to resolve before sub-tasks (default proposal in parens): + +- **3.0 Mechanism choice.** KERI-native witnesses (default), Rekor-style + append-only log, or OOBI-discovered witness set. Comparison lives in + `essays/design/multi_device.md` § "Direction of travel"; pick before + detailed planning. + +Tasks (witness-flavor-agnostic): + +- **3.1 Witness receipt ingestion.** `auths-keri/src/witness/receipt.rs` and + `first_seen.rs` are scaffolded; wire them into the verifier path so a KEL + event is "stronger" once a witness threshold (`bt`) has acknowledged it. +- **3.2 KAWA threshold validation.** Replace + `agreement.rs:89-111`'s `bt.simple_value().unwrap_or(0)` with typed + threshold satisfaction over verified-witness indices (compliance F-31). +- **3.3 Witness discovery / OOBI.** If we go KERI-native, implement OOBI + exchange. If Rekor-style, implement anchor-publication and + inclusion-proof verification. +- **3.4 Witness diversity policy.** `docs/security/witness-diversity.md` + has the design; implement the policy enforcement during witness-set + selection and `bt` validation. +- **3.5 First-seen replay.** First-seen policy from + `auths-keri/src/witness/first_seen.rs` becomes load-bearing once + witnesses ratify; ensure recovery-rotation supersedes interaction per + spec (compliance F-30 confirms current implementation is correct, but + needs integration tests under realistic witness flows). + +Verification: a verifier with access to `bt`-of-`b` witnesses always +converges on the authoritative KEL state regardless of which controller it +last synced with directly. + +### Epic 4 — KERI spec-compliance / cross-impl interop + +**Closes:** "KERI wire-format divergence" risk. +**Prerequisites:** None functionally; can run in parallel with Epics 1–3. +**Why parallel:** Each fix lands one spec deviation at a time. Bundling +behind Epics 1–3 would block interop on multi-sig schedule. + +Tasks (numbered by `keri_compliance.md` finding ID): + +- **4.1 (F-01) Move `dt` out of event body.** Either CESR attachment group + or external receipt anchor. Stops timestamps from entering SAID digest. +- **4.2 (F-06) Sign over finalized event bytes.** Remove the `d`/`i`-clearing + in `serialize_for_signing` (`validate.rs:766-797`); sign the bytes that + carry the populated SAID and prefix, matching KERIpy/KERIox. +- **4.3 (F-14) Delete mobile FFI KERI duplicate.** `crates/auths-mobile-ffi` + reuses `auths_keri::{IcpEvent, compute_said, compute_next_commitment, + finalize_icp_event}`.

Update `keys.rs::cesr_prefix` and + `auths-crypto::key_ops` together; `KeriPublicKey::parse` accepts both + with transferability variant on the parsed type. +- **4.5 (F-16) Pre-rotation commitment domain.** Decide: hash raw pubkey + bytes (current) or CESR-qualified bytes (KERIpy convention). Empirical + cross-impl test required. If we keep raw, document as deliberate + deviation. +- **4.6 (F-04, F-13) Threshold sanity at structural validation.** `kt`, + `nt`, `bt` validated against their respective list lengths at every + ingestion point. +- **4.7 (F-10, T-01) Seal `Said`/`Prefix` types.** Remove `Default` derive, + scope `new_unchecked` to `pub(crate)`. Eliminates the empty-SAID forgery + surface that interacts with finding F-06. +- **4.8 (F-35, F-36) Seal-shape spec compliance.** Migrate off `SealType` + enum; implement the spec's Event Location seal; isolate + `MerkleRoot` / `RegistrarBacker` extensions behind a feature flag. + +Verification: KERIpy ingests an auths-produced KEL and replays it without +errors; auths ingests a KERIpy-produced KEL and validates every event. + +### Epic 5 — Heterogeneous-curve controller sets + +**Closes:** Mixed P-256 + Ed25519 controllers (Vision item 4). +**Prerequisites:** Epic 1 (code-directed attachment parser) and Epic 4 +(P-256 verkey code fix). +**Why fifth:** Useful but lower urgency than the security epics.

It lives in the choices — in what the builders refused to do, in the corners they would not cut, in the things they treated as non-negotiable when it would have been easier to compromise. You can read a project's real values far more reliably from its code than from its homepage, because the homepage is what a team wishes it believed and the code is what it actually believes when no one is watching and the deadline is close. + +Most projects, read this way, turn out to be incoherent. They profess one philosophy in their mission statement and practice a different one in their commits. They talk about security and ship the convenient shortcut. They talk about openness and quietly centralize. This is not usually hypocrisy; it's entropy. Holding a single conviction steady across thousands of small decisions, under pressure, over time, is genuinely hard, and most software is a compromise between what its makers meant and what they could get away with. + +Auths is unusual, and the unusual thing is not any single idea. It's the *coherence*. There is one conviction at the center of this project, and it survives the entire trip from the smallest helper function to the largest claim about how human beings should be able to trust each other. The way the project insists you write a line of code and the way it insists strangers should verify a signature turn out, on inspection, to be the same belief wearing different clothes. That consistency — a philosophy that holds its shape at every altitude — is the most interesting thing about it, and it's worth tracing, because it tells you something not just about this project but about what integrity in a system actually means. + +## The conviction, stated plainly + +Here is the whole philosophy in one sentence: **trust nothing you could instead make explicit and check.** + +That's it. Everything else is that sentence applied at a different size. Don't assume; declare. Don't infer; verify. Don't ask anyone to take your word — not the user, not the next programmer, not yourself six months from now, and above all not a stranger who has to decide whether to believe your software. The project's name for its own deepest commitment might as well be the title of this essay: *don't take my word for it.* Wherever there is a choice between "you'll just have to trust that this is right" and "here is how you can confirm it for yourself," this project reaches, every single time, for the second option — even when the first would be faster, simpler, and good enough. + +It sounds almost too simple to be a philosophy. But watch what happens when you follow it down to the smallest scale and then back up to the largest, and you find that this one rule, taken seriously, reorganizes everything. + +## At the smallest scale: engineering as ethics + +Start at the bottom, in the unglamorous interior where most of a project's real character is hidden, and watch the conviction operate on choices so small they'd normally be beneath notice. + +When this code encounters a key, it refuses to guess what kind of key it is by looking at its length — even though the length is right there, even though guessing would work almost every time. It insists instead that every key carry an explicit label saying what it is. To a casual eye this is a fussy little rule about data formats. It is actually the whole philosophy in miniature. Guessing from length is *assuming*. Carrying a label is *declaring*. The project treats the convenient assumption as a hazard precisely because it usually works — a thing that's right ninety-nine times and silently wrong the hundredth is more dangerous than a thing that's obviously broken, because you learn to trust it before it betrays you. So the rule is: never let the system infer what it could instead be told. Make the implicit explicit. Don't take the length's word for it. + +The same conviction shows up in how the code handles time. Most software, when it needs to know what time it is, simply reaches out and grabs the clock — time is treated as an ambient fact, always available, like gravity. This project forbids that in its core. The current time must be *handed in*, passed as an argument, made a visible dependency rather than an invisible one. Why impose that discipline? Because a function that secretly reaches out and grabs the time is a function you can't fully reason about or test — its behavior depends on something it never admitted it depended on. The rule makes the dependency honest. The world is an input, not an assumption. Don't take the clock's word for it; have it given to you, on the record. + +And the same conviction governs how the code treats failure. There's a strict discipline against the lazy shortcuts that let a program pretend nothing can go wrong — the moves that quietly assume success and crash if they're wrong. Instead, every way a thing can fail must be given a name and handled, and on the rare occasions a programmer claims a particular failure is truly impossible, they're required to write down *why*, in a comment, so the claim itself can be checked. Take failure seriously. Don't assume things will work; account for the ways they won't. Don't even take your own confidence on faith — prove it. + +None of these is a technical detail in any way that matters. They are ethical positions about how to build, and they are all the same position: *do not ask the system, or the next person, or yourself, to trust what could instead be made explicit and verified.* The project applies to its own internals exactly the standard it intends to apply to the world. It does not take its own word for it. + +## The cardinal sin: silent wrongness + +Spend enough time with these small rules and you notice they all have the same enemy. The thing the philosophy is really organized against is not failure — failure is fine, failure is expected, failure gets a name and a handler. The thing it cannot abide is *silent* wrongness: the system that is broken but does not say so, that produces a confident answer that happens to be false, that fails in a way that disguises itself as a different and lesser problem. + +This is why guessing a key's type from its length is treated as something close to a moral failing. When the guess is wrong, the system doesn't announce "I have misidentified this key." It announces something else entirely — a generic complaint that points the investigator in exactly the wrong direction, sending them to debug a problem they don't have while the real one hides. The bug doesn't just fail; it *lies about how it failed.* And a system that lies about its failures is, in the deepest sense, untrustworthy — not because it's malicious, but because it has forfeited the one thing that makes a system worthy of trust: that when it tells you something is fine, it's fine, and when something is wrong, it says so. + +Here is where the philosophy reveals its true shape. Honesty is being treated as a *technical property* — something you engineer into a system, not a virtue you hope its makers possess. The relentless insistence on explicit labels, named failures, injected dependencies, and proven assumptions is all in service of one goal: building a thing that cannot fail silently, that is structurally incapable of confidently telling you a falsehood. A system you can trust is not a system that never breaks. It's a system that cannot break without telling you. The whole apparatus of small disciplines exists to make the software honest in a way that doesn't depend on anyone being honest. + +## At the middle scale: where knowledge is allowed to live + +Climb up a level, from individual functions to the shape of the whole, and the same conviction is waiting. + +This project has strong, almost severe opinions about *where* different kinds of knowledge are allowed to live. The real logic — the rules about identity, the decisions about trust, the meaningful work — must reside in a place where it can be reused and tested in isolation, never smuggled into the thin outer layer that happens to be talking to a user at the moment. The command-line surface is not allowed to know things the rest of the system doesn't. The presentation is kept deliberately dumb so that the intelligence lives somewhere honest. + +This looks like ordinary good architecture, and it is, but underneath it is the same belief again. The location of a piece of logic is a statement about its status. Knowledge buried in a disposable surface is a convenient local hack pretending to be a general truth; knowledge placed where every consumer can reach and verify it is a truth claiming its proper status as a truth. The project refuses to let convenient hacks masquerade as real rules. It insists the architecture be *legible* — that you can look at the system and see where the truths are, plainly, rather than discovering them scattered in whatever corner was expedient. Don't take the structure on faith; make it so the structure announces what it is. The refusal of the tangled monolith is, at bottom, the same refusal as the rejection of the length-guess: a refusal to let things be implicit and unverifiable when they could be explicit and checkable. + +## At the largest scale: the refusal of the allowlist + +Now go all the way up, to the level where this stops being a project about software and becomes a project about people, and watch the identical conviction arrive fully grown. + +The entire point of Auths is to let a stranger verify who made something without trusting any authority in between. And the deepest design decision in the whole system — the line the project draws and treats as the difference between meaning something and meaning nothing — is its refusal of the allowlist. It would be easy, and it's how nearly everyone does it, to establish authority by *assertion*: some trusted party signs a note that says "this device belongs to this person, take my word for it," and everyone downstream trusts the note. The project rejects this with something like contempt. Authority, it insists, must not be a thing an authority *asserts*. It must be a thing a stranger can *derive* — reconstructed from a public, checkable record by someone who never met you and trusts no one's say-so, including yours. + +Read that next to the rule about not guessing a key from its length and feel them click into place. They are the same sentence. *Don't take my word for it; here is how you can check.* The smallest rule in the codebase and the largest claim about how trust should work between human beings are not two philosophies that happen to coexist. They are one conviction, scaled. The project writes its functions the way it wants the world to verify its identities, because it is the same belief either way: nothing should have to be taken on faith that could instead be made explicit and confirmed. The refusal to let a length silently stand in for a label and the refusal to let an authority silently stand in for proof come from the identical place. That is what coherence looks like when a project actually has it — not a slogan repeated at every level, but a single conviction that genuinely produces the choices at every level. + +## The virtues that follow + +Once you see the central conviction, the project's other characteristic traits stop looking like separate values and reveal themselves as things that *had* to be true, given the center. + +Consider its honesty about itself. The project keeps documents that catalog its own weaknesses in plain, almost clinical language — naming its shortcuts as shortcuts, its broken edges as broken, its gaps as gaps, in a register closer to an incident report than a brochure. Where does this come from? It is not a personality quirk of the authors. It is *required* by the philosophy. A system whose entire pitch is "don't trust me, verify" cannot then turn around and be dishonest about its own state without becoming a hypocrite at its foundation. The commitment to verifiability obligates the commitment to self-honesty. You cannot ask the world not to take your word for your software's correctness while taking your own word for its readiness. The candor isn't generosity. It's consistency. + +Consider its humility about how much it asks you to trust. The project is almost aggressive about minimizing the number of things that must be believed for the whole to work — no central server to trust, no authority to trust, no new empire anyone has to adopt and then depend on. This, too, follows from the center. If your conviction is that trust should be derived rather than assumed, then every party a system forces you to trust is a small defeat — a place where, despite everything, you're back to taking someone's word for it. So the philosophy drives relentlessly toward *fewer* trusted parties, not as a political ideology about decentralization but as the natural endpoint of "trust nothing you could instead check." The fewer things you must believe, the more trustworthy the whole. Decentralization here is not the goal; it's the residue of the goal. + +And consider its pragmatism — the way it grades its work against whether it serves the actual purpose rather than against abstract purity, the way it's willing to be meticulously, byte-for-byte faithful to an established standard where faithfulness buys real interoperability, and willing to deviate where dogma would cost more than it's worth. This looks, at first, like it's in tension with all the rigor. It isn't. The rigor was never about worshipping rules; it was about serving a goal — building something a stranger can trust without faith. The discipline is in service of the purpose, and so the purpose, not the discipline, gets the final vote. A philosophy that had hardened into purity-for-its-own-sake would have lost the plot. This one remembers that the point of refusing to take things on faith is to build something *worth* trusting, and keeps its eyes on the something. + +## What it amounts to + +Step back from all of it and the moral shape of the thing comes into view, and it's larger than software. + +Trust that must be granted is trust the powerful control. When being believed requires a vouching authority — a platform, an issuer, a gatekeeper with a stamp — then the authority decides who is worthy of belief, and the ability to be trusted becomes one more thing the strong dispense to the weak. The whole history of brokered trust is also a history of gatekeeping, because every middleman is also a bouncer. So when this project insists, down at the level of a single function, that nothing should have to be taken on faith that could instead be verified, and then follows that insistence all the way up until it becomes a claim that a stranger should be able to confirm your identity with no authority's permission — it has, almost as a byproduct, made a statement about power. To make trust derivable is to make it ungated. To say "don't take my word for it, check" is to say "no one should have to be granted the right to be believed." The engineering conviction, followed to its end, turns out to have been an ethical one the whole time. The math that refuses to guess a key from its length is the same math that refuses to let the powerful decide who is real. + +That is the philosophy of Auths, and its signature is not any one of these positions but the fact that they are all the same position. Most systems wear their philosophy as a costume — professed in the manifesto, abandoned in the implementation. This one has a conviction that holds its exact shape from the smallest, most private decision a programmer makes alone at night to the largest, most public claim about how human beings should be able to trust one another across distance and difference, with no one standing in between. A system that refuses to be taken on faith, built by people who refuse to take their own work on faith, in service of a world where no one has to take anyone's word for anything. It is the same belief, all the way down. Don't take mine for it. That's rather the point. diff --git a/docs/essays/proof-not-permission.md b/docs/essays/proof-not-permission.md new file mode 100644 index 00000000..26c6f430 --- /dev/null +++ b/docs/essays/proof-not-permission.md @@ -0,0 +1,73 @@ +# Proof, Not Permission + +### For all of history, trusting a stranger meant trusting someone in the middle. We are about to find out what happens when that stops being true — and the timing could not be more urgent. + +Every society that ever grew past the size of a village ran into the same wall. You can trust the people you know — your family, your neighbors, the merchant whose face you've seen a thousand times. But the moment a society gets large enough that you must deal with strangers, trust becomes a problem that has to be *engineered*. You cannot personally vouch for the person on the other end of the transaction. So civilizations invented machinery to vouch on their behalf. + +The wax seal pressed with a signet ring. The notary's stamp. The letter of introduction. The bank that stands behind the check. The passport, the diploma, the certificate of authenticity. Look closely at every one of these and you find the same architecture underneath: a trusted third party in the middle, an institution everyone agrees to believe, so that two strangers don't have to believe each other directly. Trust between strangers has always been brokered. We don't trust the message; we trust the seal. We don't trust the traveler; we trust the embassy that issued the papers. The middleman is so deeply woven into how human trust works that most people have never once noticed it's there. + +Software inherited this architecture and made it bigger than anything in history. When you log in, when you download an app, when your browser shows the little lock, when a company ships an update to a billion phones overnight — every one of those moments is brokered by an institution standing in the middle, swearing that the thing you're about to trust is what it claims to be. We built the most consequential infrastructure humanity has ever produced — the code running our hospitals, our power grids, our money, our elections — and we secured it the only way we knew how: by appointing middlemen, and trusting them. + +For a long time, that was fine. The middlemen were mostly competent, mostly honest, and mostly invisible, which is exactly how good infrastructure is supposed to feel. But three things are happening at once now, and together they are turning the middleman from a convenience into a liability. The first is that the middlemen keep failing — getting breached, getting coerced, getting bought, going down. The second is that we are entering an era where almost anything can be convincingly faked, which makes the question of origin suddenly precious. And the third is that we are about to hand enormous power to machines that act on our behalf, which means we will soon need to trust not just strangers, but *strangers' software agents*, at a scale and speed no human middleman could ever broker. + +This is an essay about a small project named Auths, and a large idea: that the middleman, after thousands of years, might finally be optional. Not replaced by a bigger, better middleman — that's the trap everyone falls into — but removed. That trust between strangers could become something you *prove* rather than something you have to *be granted*. And that the difference between those two words, proof and permission, is going to matter more in the next decade than almost anyone has yet realized. + +## The quiet tax we've all agreed to pay + +Start by noticing the thing you've stopped noticing. + +Almost everything you "have" online, you don't actually own. You have an account, which is a permission a company extends to you and can revoke at will. Your handle, your history, your reputation, your reach — all of it lives at the pleasure of a platform that can suspend you, rename you, shadow you, or vanish you, often with no explanation and no appeal. You are a guest in every room you spend your digital life in. This feels normal because it has always been this way, but it is worth saying plainly: in the digital world, your identity is not a possession. It is a privilege, dispensed by an intermediary, contingent on their continued goodwill and existence. + +The cost of this arrangement is usually invisible until the day it isn't. The breach that exposes a hundred million people because everything was pooled in one trusted place. The platform that changes its rules and erases a livelihood overnight. The single company that goes down and takes a slice of the economy with it. The authority that gets quietly leaned on by a government and starts vouching for things it shouldn't. We have built a world where trust is centralized, and centralized trust has a brittleness that no amount of competence can fully engineer away. When everyone has to believe the same few institutions, those institutions become both the load-bearing walls and the single points of failure. They are too important to fail and therefore too important to be safe. + +And we pay a subtler tax than fragility. We pay in *agency*. Because trust is brokered, the brokers set the terms. They decide who gets to be believed, who gets verified, who gets the blue check and who doesn't. Trust becomes a thing the powerful dispense to the rest of us, and the ability to be believed — which is one of the most fundamental things a person or a creator or a business can have — becomes something you apply for. The middleman doesn't just connect strangers. He sits at the gate, and gates have keepers, and keepers have preferences. + +We have lived with this so long we've mistaken it for the nature of things. It isn't. It's just the only architecture we'd ever had — until the math caught up. + +## The thing that makes this suddenly urgent + +If the case against the middleman were only about fragility and fairness, it would be a worthy but slow-moving argument, the kind of thing reasonable people improve gradually over decades. It is not slow-moving anymore, because the ground is shifting underneath it. + +We are crossing into a world where the default assumption about any digital artifact is going to flip. For the entire history of media, the baseline assumption was that what you saw was probably real, and fakes were the exception you had to watch for. That baseline is dying. When anyone can generate a flawless photograph of an event that never happened, a video of a person saying words they never said, a piece of code that looks exactly like the work of someone you trust — then "probably real" stops being a safe default. The exception becomes the rule. And in a world where everything can be faked, the only thing that has value is the thing that can be *proven*. Provenance — the verifiable answer to "who actually made this, and can they show it" — stops being a nice-to-have and becomes the scarcest and most important property a digital thing can possess. + +This is the great inversion of the coming decade. We are moving from a world where the question "who made this?" was a curiosity to a world where it is the load-bearing question of the entire digital economy. Did this software update really come from the company whose name is on it, or from an attacker who slipped into the supply chain? Did this statement really come from this person, or from a machine wearing their face? Did this transaction really originate from the human it claims, or from an autonomous agent that exceeded what it was allowed to do? In each case, everything downstream — your safety, your money, your trust in the institution involved — hangs on an answer that, today, you mostly cannot get without trusting yet another middleman to give it to you. + +And then there are the agents. We are about to delegate real authority to software that acts for us — writing, buying, signing, deciding, at machine speed, around the clock, with no human in the loop at the moment of action. This is the part the world is least prepared for. An agent that can act on your behalf needs to be able to prove three things to anyone it interacts with: that it really is the agent it claims to be, that a real person or organization actually authorized it, and that the specific thing it just did fell inside the bounds of what it was allowed to do. Today we hand agents the digital equivalent of a borrowed house key — a secret that proves possession but says nothing about permission, can't express limits, and can't be traced back to the human who handed it over. That is a fine arrangement for a world with a few hundred such agents. It is a catastrophe waiting to happen in a world with a few billion. The era of autonomous action is going to demand a way to prove authorization that doesn't route every single act through a trusted broker — because there will be too many acts, too fast, for any broker to sit in the middle of. + +Put these together — the collapse of "probably real," the rise of provenance as the scarce good, the imminent flood of agents acting on our behalf — and you arrive at a single conclusion. The world is about to need verifiable trust between strangers at a scale and speed that the middleman model physically cannot serve. Not won't. Cannot. The architecture that got us here doesn't go where we're going. + +## From permission to proof + +Here is the move that changes everything, stated as simply as it can be: take the trust out of the institution and put it into the thing itself. + +Instead of an artifact that proves nothing on its own and leans on an authority to vouch for it, imagine an artifact that carries its own proof — a proof that anyone, anywhere, can check for themselves, without asking anyone's permission, without trusting any company, without a server in the middle that has to be honest and online. The proof isn't a stamp from an authority. It's mathematics, and mathematics doesn't have a headquarters, doesn't get breached, doesn't get coerced, doesn't go out of business, doesn't play favorites, and doesn't require you to believe it on faith. You can simply check. + +This is the difference between permission and proof, and it is not a small upgrade. It is a change in the kind of thing trust is. + +Under the old model, your identity is something you are *granted* — handed down by an authority that can take it back. Under the new one, your identity is something you *own* — rooted in mathematics that belongs to you and no one else, that no platform issued and no platform can revoke. Under the old model, to be believed you must be vouched for. Under the new one, you carry your own evidence, and the person on the other end doesn't have to trust you, or trust your vouchers — they verify, directly, the way you'd check a sum rather than take someone's word for the total. The gatekeeper doesn't get nicer. The gate disappears. + +What makes this genuinely radical is who it serves. When trust is brokered, it flows downhill from the powerful. When trust is provable, it belongs to everyone equally, because mathematics is the one authority that treats a solo developer in one country exactly the same as a giant corporation in another. The ability to prove who you are and what you made — to be believed by strangers without an institution's blessing — stops being a privilege the system grants the worthy and becomes a property anyone can simply have. There is a word for the condition of not needing anyone's permission to be believed. The word is sovereignty, and it has been, until now, almost entirely absent from our digital lives. + +## Why this attempt might be the one that works + +The graveyard of this idea is enormous. The dream of trust without a middleman — of identity you own rather than rent — is decades old, and it is littered with brilliant, beautiful failures. So the honest question is not whether the idea is good. The idea has always been good. The question is why anyone should believe this time is different, and the answer is more interesting than it sounds, because it has nothing to do with cleverer cryptography. + +Almost every previous attempt to remove the middleman made the same fatal mistake: it asked the world to adopt a whole new empire in order to escape the old one. A new network everyone had to join. A new ledger everyone had to agree on. A new coin, a new chain, a new foundation, a new thing to stand up, fund, and maintain forever. In trying to abolish the trusted third party, they accidentally built a different trusted third party and asked everyone to migrate to it. The friction was enormous, the cold start was brutal, and most of them died of it. They demanded that the world change its habits to gain its freedom, and the world, as it always does, declined. + +The quietly profound bet behind Auths is to do the opposite: to ask the world to adopt *nothing*. To build the whole thing on top of the tools people already use every single day, so that there is no new empire to erect, no network to bootstrap, no migration to suffer, no foundation that someone has to keep alive with donations in perpetuity. The infrastructure is already deployed, already everywhere, already understood, already trusted with the most important work in software. The genius isn't a new tower. It's the refusal to build one. It meets people exactly where they already are and gives them ownership of something they didn't know they were renting — and it does it without asking them to believe in anything except math they can check. + +That humility is the whole strategy, and it's why this attempt has a shape the failures never did. The previous dreamers tried to win by being a better authority. This one tries to win by making authority unnecessary, on rails the world already rides. The first is a fight you have to convince everyone to join. The second is a door you simply open. + +It would be dishonest to pretend the path is clear. The deepest problem in trust between strangers is the very first encounter — the moment you meet an identity for the first time and have to decide whether the person behind it is who you think. Proof can tell you an identity is internally consistent and that its history is unbroken; it cannot, by itself, tell you that the human behind it is the human you mean. That first leap will always require something from the world outside the math — a context, an introduction, a public record, a reputation built over time. Removing the middleman doesn't remove the need for judgment at the very beginning. It removes the need to keep trusting an intermediary forever after. That is a more modest claim than "we have abolished trusted third parties," and its modesty is exactly why it might be true. + +## The world on the other side + +So imagine it's done. Not the mechanism — the feeling of it. What is it like to live in a world where trust is something you prove rather than something you're granted? + +A developer signs their work, and their work carries its own evidence wherever it goes — into a package downloaded a million times in a country they'll never visit, verified by a stranger who never had to trust the developer, or trust any company, or trust anything but the proof itself. A creator can establish that a piece of work is theirs in a world drowning in convincing fakes, not by petitioning a platform for a badge, but by carrying a proof no platform issued and none can take away. A person hands real authority to an agent and can scope it precisely — this much, for this purpose, until this date — and anyone the agent deals with can verify, instantly and without a broker, that the agent was authorized and stayed within its bounds. The alternative to that world — a flood of autonomous software acting with un-checkable authority, in a sea of un-provable content, all of it brokered by institutions too important to fail and too central to be safe — is the dystopia this quietly prevents. + +And underneath all of it, a shift so fundamental it's easy to miss: trust stops being a relationship of dependence and becomes an act of verification. You no longer have to believe the powerful when they tell you what's real. You can check. The seal, the stamp, the certificate, the badge, the platform's blessing — the entire apparatus of brokered belief that humanity has leaned on since the first city — becomes, for the first time, optional. Not because we found a more trustworthy authority, but because we no longer need one to stand in the middle of every act of trust. + +That is the amazing thing, and it has almost nothing to do with technology. It's that identity — the most personal thing a person has, the thing that lets you be believed, that lets you own your reputation and your work and your word — stops being something you're permitted to have and becomes something you simply hold. It travels with you. It answers to no one. It extends, when you choose, to the machines that act in your name. And it lets a stranger believe you not because someone vouched for you, but because you can prove it, and they can check. + +Civilization spent thousands of years building ever-larger institutions to let strangers trust each other. This is the first serious attempt to let strangers trust each other with no institution in between at all — to replace permission with proof, and to do it so quietly, on ground so familiar, that one day people may simply wake up owning something they never realized had been borrowed all along. That's not a better mousetrap.

Executive Summary + +Auths is a decentralized, Git-native identity and code-signing system. The cryptographic core is well-constructed: signatures cover a comprehensive canonical envelope (role, capabilities, delegation, and signer-type fields are all signed and tamper-tested), curve tags are carried in-band, key material is zeroized, and the verifier is a dependency-minimal pure function suitable for embedding. The team also maintains an unusually candid internal risk register (`docs/architecture/multi_device_accepted_risks.md`), which materially improved the quality of this review. + +That said, the audit identified **one Critical authorization-bypass** in the verification path, along with several High and Medium issues concentrated in three themes: (1) **fail-open defaults** in the verifier, (2) **opt-in rather than default-on security checks**, and (3) **revocation and freshness** weaknesses inherent to the serverless model that are currently unmitigated at the verifier boundary. + +The Critical finding (AUTHS-2026-001) is the priority: the verifier silently skips issuer-authorization when an attestation omits its issuer signature, which allows forgery of "trusted identity vouches for attacker device" attestations.

The verifier checks the device signature unconditionally, but gates the issuer signature on its presence: + +```rust +// verify.rs:357 +if !att.identity_signature.is_empty() { + verify_signature_by_curve(issuer_pk, data_to_verify, + att.identity_signature.as_bytes(), provider, SignatureRole::Issuer).await?; +} else { + debug!("(Verify) No identity signature present (device-only attestation), skipping issuer check."); +} +``` + +When `identity_signature` is empty, the issuer-authorization check is **silently skipped** and verification proceeds to validate only the device signature. The `Ed25519Signature::empty()` constructor and the `skip_serializing_if = "is_empty"` serde attribute on the field make an empty issuer signature a normal, serializable wire state — and `create.rs:193-195` deliberately emits exactly this shape whenever no identity alias is supplied ("device-only attestation"). + +The verifier provides no typed distinction between a *device-only self-assertion* (legitimately verified against the device's own key) and an *authority-bearing delegation* (which must carry an issuer signature). `verify_chain`, `verify_with_keys`, `verify_device_authorization`, and `verify_device_link` all route through `verify_with_keys_at` and therefore all inherit the skip. + +**Impact.** +An attacker who controls *any* device key can forge an attestation that a trusted identity never authorized: + +1. Construct `att { issuer = , subject = , device_public_key = , identity_signature = empty, device_signature = }`. +2. Call `verify_chain(&[att], &victim_root_pk)`. +3. At step 0, the issuer check (against `victim_root_pk`) is skipped because the signature is empty; the device signature validates against the attacker's own key; the function returns `VerificationStatus::Valid`. + +The result is a complete bypass of issuer authorization — "root vouches for attacker's device with capability X" — accepted by every consumer of the verifier, including the WASM/FFI builds embedded in CI gates, git hooks, and mobile clients. The same construction forges interior chain links (set `issuer = prev.subject`) and forges device-authorization in `verify_device_link` (subject matches, issuer check skipped). The existing test `verify_at_time_signature_always_checked` (`verify.rs:933`) only exercises a *tampered* (non-empty, invalid) signature; no test asserts that an *absent* issuer signature is rejected in an authority context. + +**Recommendation.** +Make the absence of an issuer signature a verification failure in any authority-bearing path. Concretely: + +1. In `verify_with_keys_at`, treat an empty `identity_signature` as `AttestationError::IssuerSignatureFailed("missing issuer signature")` by default. Do **not** skip. +2. If device-only self-assertions are a genuine use case, model them as a distinct, explicit API (e.g. `verify_self_attestation(att)`), which requires `issuer == subject` and `device_public_key` to match, and which callers must opt into deliberately — never reachable through `verify_chain` / `verify_device_authorization`. +3. Add negative tests: an attestation with `identity_signature = empty()` must fail `verify_chain` and `verify_device_link`. +4. Consider making `identity_signature` a non-optional field on the authority-bearing attestation type so "absent" is unrepresentable at the type level. + +--- + +### AUTHS-2026-002 — Capability confinement is opt-in; default chain verification ignores capabilities + +- **Severity:** High +- **Component:** `auths-verifier` +- **Files:** `crates/auths-verifier/src/verify.rs:124-131` (`verify_chain`), `:73-82` (`verify_chain_with_capability`) + +**Description.** +Attestations carry a signed `capabilities` list (`sign_commit`, `sign_release`, `manage_members`, `rotate_keys`) intended to scope what a delegated key may do. Capability enforcement, however, lives only in the `*_with_capability` variants. The default `verify_chain` / `verify_with_keys` entry points validate signatures and chain linkage but **do not check capabilities at all**, and they do not enforce capability *attenuation* down the chain except in the opt-in path (`verify_chain_with_capability` computes an intersection — see test `verify_chain_with_capability_uses_intersection`, `verify.rs:1356`). + +**Impact.** +A consumer that calls the obvious, default `verify_chain` to validate a release-signing operation will accept a key that was only ever delegated `sign_commit`, because capabilities are never consulted on that path. Capability scoping is a primary authorization control here; making it opt-in means the secure behavior depends on every caller remembering to choose the longer function name. This is a classic "insecure default" — the safe path should be the default path. + +**Recommendation.** +- Require callers to pass the operation's required capability (or an explicit `Capability::None`/"any" sentinel) so that omitting the check is a deliberate, visible choice rather than the default. +- Enforce capability attenuation (child capabilities ⊆ parent capabilities) inside `verify_chain_inner` so an interior link cannot amplify authority, independent of the final capability assertion. +- Document, at the API level, that `verify_chain` alone does not authorize an *action* — only an identity binding. + +--- + +### AUTHS-2026-003 — No revocation propagation / freshness guarantee at the verifier boundary + +- **Severity:** High +- **Component:** `auths-verifier`, design +- **Files:** `crates/auths-verifier/src/verify.rs:322-327` (revocation check), `:514-529` (`verify_single_attestation`) + +**Description.** +Revocation is modeled as a field (`revoked_at`) on the attestation and as a separate signed revocation attestation.

There is no CRL, no OCSP-equivalent, no transparency-log freshness proof, and no "this attestation must be re-checked against current KEL state" requirement at the verification boundary. + +**Impact.** +Revocation is the control you reach for *after* a compromise. If a verifier can be kept from learning about a revocation — by network partition, a stale mirror, or simply being passed the raw attestation without the surrounding repository — a revoked (e.g. stolen-laptop) device key continues to verify as valid.

The risk concentrates in **relay/online mode**, where the channel is not inherently out-of-band and an active network attacker between the two devices is in scope. + +**Impact.** +In relay mode without `--verify`, a MITM who can sit between initiator and responder during the 5-minute window could complete a pairing the user believes is authenticated. The attestation payload itself is protected by a ChaCha20-Poly1305 transport key derived from the ECDH secret, so confidentiality of the payload holds against a passive attacker — but an *active* MITM that completes its own ECDH with each side is precisely what the SAS exists to catch, and that catch is off by default. + +**Recommendation.** +- Make SAS confirmation **default-on for relay/online pairing**, and opt-out (`--no-verify`) rather than opt-in.

The team's own assessment: internally consistent, but cross-implementation interop with KERIpy/KERIox/Signify is currently broken. + +**Impact.** +Primarily interoperability and semantic correctness rather than direct exploitability. The `1AAI` reuse is the one with security flavor: a strict third-party KERI verifier could misinterpret transferability (treating a rotatable identity as non-transferable, or vice versa), which is a silent-correctness hazard if Auths identities are ever consumed outside the Auths verifier. + +**Recommendation.** +- Track to the planned KERI-compliance epic.

The type-state pattern is good, but `VerifiedAttestation::dangerous_from_unchecked` (used in tests) exists, and a careless caller could construct the "verified" wrapper without verifying. + +**Impact.** +Not a vulnerability in itself; a misuse hazard. If a consumer ever wraps unverified attestations in `VerifiedAttestation`, every downstream check that trusts the type is bypassed. + +**Recommendation.** +- Keep `dangerous_from_unchecked` `#[cfg(test)]`-only or `#[doc(hidden)]` with a deny-by-default lint, so it cannot be reached from production code. +- Document the type-state contract on `VerifiedAttestation` explicitly. + +--- + +## 3.

This closes a large class of field-injection attacks. +- **In-band curve tagging.** The architecture forbids length-based curve dispatch and parses to curve-aware typed values (`KeriPublicKey`, `DecodedDidKey`, `TypedSeed`). This eliminates a real silent-misrouting hazard. +- **Key zeroization.** `TypedSeed` and the pairing `TransportKey` are `Zeroize`/`ZeroizeOnDrop` and move-consumed, preventing reuse and reducing memory-exposure windows. +- **Pre-rotation.** The next-key commitment model (`rotation.rs`) means a stolen *current* signing key cannot rotate the identity — strong forward security for the identity itself. +- **Minimal-dependency verifier.** No `git2`, no HTTP in the verification core; pure-function verification suitable for WASM/FFI sandboxing. +- **Clock injection.** `Utc::now()` is banned in domain code; time is injected, making time-dependent logic testable and deterministic (`MAX_SKEW_SECS`, `verify_at_time`). +- **Honest internal risk register.** `multi_device_accepted_risks.md` documents the `kt=1`, no-witness, and interop gaps in plain language.

Findings AUTHS-2026-007 (relay rate-limiting) and AUTHS-2026-009 (KERI interop) are partly informed by project documentation and a targeted grep rather than exhaustive reading of the daemon and `auths-keri` internals; both are flagged for confirmation rather than asserted as exploitable. No dynamic testing, fuzzing, or proof-of-concept exploitation was performed — findings are from static analysis and should be validated with regression tests as part of remediation. +- **Not in scope this pass:** keychain/platform-credential integration, the registry/storage adapters' concurrency and atomic-write guarantees, witness-receipt validation internals, and the OIDC binding path.

A small project called Auths is betting that the answer was sitting in plain sight — and that the timing has finally caught up to the idea. + +There is a question so basic that the entire edifice of modern software has learned to simply not ask it: *who made this?* + +Not "who does the commit say made it" — anyone can type a name. Not "who has push access" — that's a list someone administers, somewhere, revocable on a whim. The real question, the cryptographic one: when a line of code, a container image, a model weight, or an autonomous agent's action lands in front of you, can the thing itself *prove* who stands behind it, without you having to trust a server, a platform, or a company's promise that its database is honest? + +For fifty years the answer has been no. We built the most important infrastructure in human history — the software that runs finance, medicine, energy, war — on an identity model roughly as rigorous as a handwritten name tag. And we got away with it, mostly, because the blast radius felt contained. Then the blast radius stopped feeling contained. A backdoor in a compression library nearly walked into every Linux server on the planet. A compromised npm token poisoned packages with hundreds of millions of weekly downloads. A signing key leaked from a vendor became a skeleton key to a continent's worth of devices. The name-tag era is ending not because anyone planned its end, but because the cost of its absence finally got too large to ignore. + +This is an essay about the landscape that absence created — the incumbents who've tried to fill it, the shape of the problem as it's growing rather than as it was, and where a Git-native identity system called Auths fits into a market that is, for the first time, genuinely up for grabs. + +## The problem is bigger than code signing + +It's tempting to file all of this under "supply chain security" and move on. That framing undersells it. What's actually happening is the slow realization that *identity* — the binding of a cryptographic key to an actor and a set of permissions — is a missing layer of the stack, and its absence shows up everywhere at once. + +Consider how many distinct actors now need to prove who they are to a machine, continuously, without a human in the loop. A developer signing a commit. A CI runner cutting a release. A container pulling a base image. A microservice calling another microservice across a mesh. A package asserting it came from the source it claims. And — the category that is about to dwarf all the others — an AI agent taking an action on someone's behalf, needing to prove both *that it is the agent it claims to be* and *that it was authorized to do the thing it just did.* + +Every one of these is the same question wearing different clothes: *prove who you are, prove what you're allowed to do, and let me check it without phoning home to someone I have to trust.* The industry has answered this question a dozen partial ways, each optimized for one actor and awkward for the rest. The interesting bet of the moment — the one Auths is making, and it is not making it alone — is that these are not a dozen problems. They are one problem, and it deserves one primitive. + +## The incumbents, honestly + +To understand where a new entrant fits, you have to give the existing players their due. The identity landscape is not empty; it's crowded with serious, well-engineered systems, each of which solved something real. + +**The certificate authorities and traditional PKI** are the old gods. X.509, the CA hierarchy, the padlock in your browser — this is the machinery that made e-commerce possible, and it works at a scale nothing else has matched. Its genius is also its limit: trust flows downward from a small set of roots that everyone agrees to trust, which means identity is something you are *granted* by an authority, not something you *own*. For the web, where you want a stranger's browser to trust your server on first contact, that's exactly right. For a developer who wants a portable, self-sovereign identity that no vendor can revoke or hold hostage, it's the wrong shape entirely. PKI gives you identity-as-a-service. A lot of people now want identity-as-a-possession. + +**GPG and the web of trust** were the grassroots answer, and their story is the most instructive in the whole field. The cryptography was sound thirty years ago and is sound today. The idea — a decentralized graph of people signing each other's keys, trust emerging from the mesh rather than descending from a root — was beautiful. And it failed, comprehensively, for one reason that should be tattooed on the wall of every identity startup: *the user experience was unusable.* Key management was a priesthood. Keysigning parties were a punchline. The web of trust never reached the density where it became useful, because getting onto it was too hard. GPG is the field's permanent reminder that in identity, ergonomics is not a feature. It is the product. + +**SSH commit signing** is the pragmatist's stopgap, and a genuinely good one. Developers already had SSH keys; GitHub and others let you reuse them to sign commits; the friction was low because the keys were already there. But SSH signing is identity without a memory. There's no rotation history, no delegation, no revocation story worth the name, no notion of "this key may sign commits but not cut releases." It proves a key signed a thing. It can't tell you the story of that key — where it came from, what it's allowed to do, whether it's still valid. It's a signature, not an identity. + +**Sigstore** is the modern leader, and it is excellent. It deserves the lead it has. Its insight was psychological as much as technical: developers hate managing long-lived signing keys, so *remove them.* Sigstore lets you sign with an ephemeral key tied to an OIDC identity you already have — your Google account, your GitHub identity — and records the act in a public, append-only transparency log so anyone can later verify it happened. The pieces (Fulcio, the short-lived-cert CA; Rekor, the transparency log; cosign, the tooling) compose into something that has done what GPG never could: it made signing *normal.* npm package provenance, GitHub artifact attestations, the SLSA framework's higher tiers — these run on Sigstore's rails, and adoption has crossed from "security teams care" into "it's just on by default." That is an enormous achievement, and any honest account of this space has to start by acknowledging that Sigstore won the first round. + +**The decentralized-identity and blockchain world** — W3C DIDs, verifiable credentials, ENS names, did:web, did:ion, the eIDAS digital-identity wallets Europe is mandating — has been circling the self-sovereign dream from the other direction. Its ambition is the right one: identity you hold, present, and prove without an intermediary. Its recurring tax has been the substrate. Anchoring identity to a blockchain buys you global consensus at the price of gas fees, latency, and the requirement that the whole world agree on one ledger — a steep toll for what is, most of the time, a local question between two parties who just need to check a signature. The vision is magnetic. The plumbing has often been heavier than the problem. + +**And the workload-identity systems** — SPIFFE/SPIRE, cloud IAM, OIDC federation — solved the machine-to-machine version of the question inside the datacenter, elegantly, for actors that live and die inside one trust domain. They are less suited to the open, cross-organizational, offline-first world where a verifier and a signer may never share infrastructure and may meet for the first time across a network neither controls. + +Look at that landscape and a pattern emerges. Each incumbent nailed one actor and one trust model. CAs own the web. Sigstore owns CI provenance. SPIFFE owns the mesh. The blockchain DIDs own the maximalist vision. *Nobody owns the developer's own portable identity* — the thing you carry across all of those contexts, that proves it's you whether you're signing a commit, authorizing a new laptop, vouching for a teammate, or delegating to an agent. That space is open. That's the space Auths is walking into. + +## Where the puck is going + +The case for a new primitive isn't built on today's landscape. It's built on where the demand is headed, because identity is one of those layers where the incumbents are optimized for the world that was, and the world is changing underneath them. + +Three vectors are bending the curve. + +The first is **the explosion of non-human identities.** For most of computing history, identities were mostly people, and people are slow — you onboard, you offboard, the churn is human-paced. That era is over. The number of machine and workload identities has rocketed past the number of human ones, and the ratio keeps climbing. Every container, function, pipeline, and service now needs to authenticate, and the existing tools strain because they were built around the assumption of a human and a password somewhere in the loop. Identity is becoming something issued and verified at machine speed and machine scale, and that rewards primitives that are cheap, offline-verifiable, and don't require a human ceremony to mint. + +The second is **AI agents**, which take the non-human-identity problem and pour rocket fuel on it. An autonomous agent that can write code, open pull requests, move money, or call APIs on your behalf needs an identity that can prove three things at once: that it is the agent it claims to be, that a specific human or organization delegated authority to it, and that the specific action it just took fell within the bounds of that delegation. This is not a hypothetical. It's the identity problem of the next decade, and it is exactly the shape — *delegated, scoped, cryptographically provable, checkable by a third party offline* — that a chain of signed, capability-bearing attestations is built to express. Whoever owns the developer-identity primitive is positioned to own the agent-identity primitive, because they're the same primitive with a different actor at the leaf. + +The third is **the regulatory and cultural normalization of provenance.** A few years ago, "every artifact should carry a cryptographic provenance attestation" was a security researcher's wish. Today it's a default in the world's largest package registry, a Docker base-image feature, an EU wallet mandate, a line item in procurement checklists. The behavior has crossed the chasm. Whether any specific government mandate tightens or loosens, the cultural fact is settled: signed provenance is becoming table stakes. And here's the strategic subtlety — as the *requirement* becomes universal but the *mechanism* stays unspecified, the competition shifts from "who can satisfy the mandate" to "who has the lowest-friction way to do it." Mandates favor incumbents with compliance machinery. Open competition on cost and ergonomics favors whoever has the simplest primitive. That shift is a door opening. + +## How Auths fits — and why the timing is the whole story + +Into this landscape walks a project with a thesis that sounds almost too simple: developers already have a shared, replicated, tamper-evident, universally-deployed database for recording history. It's Git. So put identity *there.* + +In the Auths model, your identity lives in a Git repository — your `~/.auths` directory is one — and every fact about it is a Git ref: your keys, their full rotation history, every attestation you've ever issued. There's no certificate authority to grant you a name, no transparency log someone has to operate, no chain to reach consensus on, no server to phone home to. An identity is a self-certifying history you can clone, push, diff, and back up with tools every developer already runs. Verification is a pure function: hand it the data and a trust root you pinned once, and it returns an answer offline, in a browser, in a CI runner, on a phone, with no network in the loop. + +What's striking about this is not the cryptography — the underlying ideas (key-event logs, pre-committed rotation keys, dual-signed delegation chains, capability-scoped attestations) are borrowed thoughtfully from the best of the decentralized-identity research world. What's striking is the *substrate choice*, and what it does to the cost structure of the whole problem. Every incumbent that offers decentralization asks you to adopt new infrastructure to get it: a transparency log, a ledger, a federation. Auths asks you to adopt nothing, because the infrastructure is the one piece of software a developer cannot not have. It sits precisely in the overlap of the two markets that are growing fastest — software supply chain integrity and decentralized identity — and it occupies that overlap with a primitive whose marginal operational cost is approximately zero. + +That overlap is the most valuable real estate in the field right now, and the reason is timing. Sigstore proved developers will adopt signing if you make it frictionless — it did the expensive cultural work of normalizing the behavior. The non-human-identity explosion and the agent wave are creating a flood of actors that need cheap, offline-verifiable, delegable identity. The regulatory tide is shifting from prescribed mechanisms to open competition on merit. And the one substrate that every one of those actors already touches — source control — has been sitting underneath the whole problem the entire time, unused as an identity layer. The idea was always available. What changed is that the demand finally grew into the shape of the answer. + +## The aspirational version + +Here is the world this is reaching toward. + +A developer runs one command and has a cryptographic identity they *own* — not granted by a platform, not revocable by a vendor, portable across every tool they touch. They add a second device with a two-step pairing flow that feels like linking a messaging app, not performing a key-management ritual. They sign their commits and their releases, and that identity carries a memory: a full, auditable history of which keys signed what and when, with rotation and revocation built in rather than bolted on. They vouch for a teammate, delegate a narrowly-scoped capability to a CI pipeline, hand an AI agent the authority to open pull requests but not to cut releases — and every one of those grants is a signed, verifiable, offline-checkable link in a chain that anyone can walk from a single pinned trust root. + +And the person on the other end — the maintainer pulling the package, the reviewer reading the PR, the service receiving the agent's call — can verify all of it with a function that runs in their browser or their build, with no server to trust, no log to query, no company whose honesty they have to assume. Trust becomes something you can check rather than something you have to extend. The name-tag era ends not with a bigger authority, but with no authority at all — just math, and a repository every developer already has. + +That is the aspiration, and it is a large one. It is worth being clear-eyed that aspiration is not arrival. Sigstore has a real lead and real network effects; the cold-start problem — why trust a new identity the first time you see it — is genuine and unsolved for everyone in this space, not just Auths; and a primitive is only as good as the ecosystem that grows around it. The graveyard of identity projects is full of beautiful designs that never crossed the adoption chasm, and GPG's ghost haunts every one of them with the same warning: ergonomics decides everything. + +But the structural opening is real, and it's the kind that doesn't stay open. There is a developer-owned, infrastructure-free, delegation-native identity primitive waiting to be built, the demand for it is arriving from three directions at once, and the substrate it should live on has been deployed to every machine that matters for two decades. Auths is a bet that someone is going to claim that ground, that the claiming is a question of *when* and not *whether*, and that the right place to put the root of trust was never a new tower we have to build and maintain — it was the repository, all along. diff --git a/docs/essays/the-repository-is-the-root-of-trust.md b/docs/essays/the-repository-is-the-root-of-trust.md new file mode 100644 index 00000000..f15de1ae --- /dev/null +++ b/docs/essays/the-repository-is-the-root-of-trust.md @@ -0,0 +1,116 @@ +# The Repository Is the Root of Trust + +### A small Rust project called Auths bets that the entire apparatus of code-signing — certificate authorities, transparency logs, blockchain registries — was always just an elaborate way of avoiding the one tool every developer already runs.

And the most serious modern attempt — Sigstore, the project behind `cosign` and npm's package provenance — solved the key-management problem by removing the keys entirely, at the cost of standing up a federated certificate authority (Fulcio) and an append-only transparency log (Rekor) that someone, somewhere, has to operate forever. + +Auths — a pre-launch, open-source identity system written in Rust — starts from a heretical premise: that all of this infrastructure exists to work around the fact that developers didn't have a shared, tamper-evident, replicated database to write identity into. Except they do. They've had one since 2005. It's called Git. + +## The thesis in one sentence + +Here is the entire idea: your `~/.auths` directory *is* a Git repository, and every fact about your cryptographic identity — your keys, their entire rotation history, every attestation you've ever signed — lives inside it as Git refs. There is no central server. There is no blockchain. There is no certificate authority. There is no transparency log to operate. Identity is data in a Merkle DAG you already know how to clone, push, and diff. + +This is the kind of idea that is either trivial or profound, and you can't tell which until you look at how it's built. So I read the code. What follows is a tour of the machine, because the machine is where the argument actually lives. + +## The key event log: identity as an append-only history + +The conceptual heart of Auths is borrowed from KERI — Key Event Receipt Infrastructure, a protocol that emerged from the decentralized-identity world with one genuinely good idea: your identity is not a key, it's the *log of everything that has ever happened to your keys.* + +In the codebase this log is a `GitKel` — a Git-backed Key Event Log — and it's stored, with a directness that's almost funny, at the ref path `refs/did/keri/{prefix}/kel`. Each event in the log is a Git commit. The commits form a linear chain: inception has no parent, and every subsequent event points back at the last one. To replay your identity, the verifier walks the commit chain backward to the beginning and folds the events forward into a `KeyState`. Your identity history is `git log`. + +There are three event types, and they map cleanly onto the three things that can happen to a key. An **inception event** (`icp`) is the genesis block: it declares your first key and commits to your next one. A **rotation event** (`rot`) retires the current key and installs the successor. An **interaction event** (`ixn`) anchors data — an attestation, a signed commit — without touching the keys at all. + +The clever part is how an identity names itself. Auths identities are `did:keri:` DIDs, and the string after the prefix is not derived from your public key — it's a **SAID**, a Self-Addressing Identifier, which is a Blake3-256 hash of the inception event *itself*. The computation, in `said.rs`, is a small ritual: take the event, replace the digest field `d` with a 44-character placeholder of `#` symbols, replace the identifier field `i` too (since for an inception event the identifier *is* the digest), strip any detached signatures, serialize, and hash. The resulting 44-character string — an `E` followed by 43 base64url characters — becomes both the digest *and* your permanent identifier. Your name is the hash of your own birth certificate. Tamper with any field of the inception event and the name no longer matches the content; the identity is self-certifying by construction. + +One detail in that file is worth dwelling on, because it reveals how much care went into this. The serialization for hashing is deliberately *insertion-order*, not canonical JSON — and there's a comment, and a guard test that fails the build if the JSON map type ever loses its ordering, explaining why: canonical JSON (RFC 8785, sorted keys) would produce different SAIDs and break interoperability with other KERI implementations. Someone thought about cross-ecosystem compatibility at the level of byte-ordering inside a hash preimage. We'll come back to whether that compatibility actually holds. + +## Pre-rotation: committing to a key you haven't used yet + +The single most elegant mechanism in the whole system is **pre-rotation**, and it's a genuinely good answer to the oldest problem in key management: what do you do when your key is compromised? + +In a naive system, if an attacker steals your signing key, they can also sign a "rotation" to a new key they control, and now they *are* you, permanently. KERI's answer, implemented in `rotation.rs`, is that at every step you don't just hold your current key — you've already committed, in your last event, to the *hash* of your next one. The inception event's `n` field contains `Blake3(next_public_key)`. To rotate, you must present a key whose hash matches that prior commitment; the code calls `verify_commitment()` and rejects a `CommitmentMismatch` outright. + +The security consequence is sharp. An attacker who steals your *current* signing key still cannot rotate the identity, because rotation requires the *next* key — which was generated separately, never used to sign anything, and may sit in cold storage. The active signing key and the rotation-authorizing key are different secrets with different exposure. It is forward-security applied to identity itself. There's even a notion of deliberate death: a rotation that commits to an empty next-key set sets `is_abandoned = true`, permanently sealing the identity against all future events. You can cryptographically retire a name forever. + +## Attestations: the dual-signed unit of trust + +If the KEL is who you are, the **attestation** is what you say. It's the load-bearing data structure, and the struct in the verifier crate is dense with intent. An attestation has a `version` (currently 2 — they bumped it for a curve-agnostic refactor and, being pre-launch with zero users, simply broke the old format rather than carry compatibility cruft), an `issuer` and a `subject`, a `device_public_key`, an `expires_at`, an optional `revoked_at`, a list of `capabilities` (`sign_commit`, `sign_release`, `manage_members`, `rotate_keys`), and — the crucial pair — an `identity_signature` and a `device_signature`. + +That last detail is the whole game. Attestations are **dual-signed.** When a developer's root identity vouches for a new laptop, the resulting attestation is signed *both* by the identity key and by the device's own key. The signing path canonicalizes the attestation's semantic fields with `json_canon` (RFC 8785 — note: canonical JSON *here*, unlike the KEL, because attestations don't need KERI wire-compatibility) and signs the same canonical bytes twice. The verifier checks both. The identity signature proves *authorization* — "this root vouches for this device" — and the device signature proves *possession* — "and the device actually holds the key it claims." Neither alone is enough. + +This composes into a chain. The verifier's `verify_chain()` function walks an ordered list of attestations from a known root public key, and it enforces one beautiful invariant: each link's `subject` must equal the next link's `issuer`, and the public key that authorizes link *N+1* is the `device_public_key` of link *N*. Authority flows down the chain like a delegated current. Root identity vouches for laptop; laptop vouches for a CI agent; CI agent signs a release. A verifier with nothing but the root public key can validate the entire delegation by walking the links — and if any `issuer→subject` seam doesn't match, it returns a `BrokenChain` with the missing link named. + +## The verifier that fits anywhere + +Here is where the architecture earns its keep. The verification logic lives in `auths-verifier`, a crate engineered to be *embeddable*, which in practice means engineered for what it refuses to depend on. It does not pull in `git2`. It does not pull in an HTTP client. It does not require `tokio` unless you ask for the FFI feature. Its dependency list is `serde_json`, `json-canon`, `chrono`, the crypto primitives, and the KERI types — and that's nearly it. + +The payoff is a verifier that compiles to WebAssembly and to a C FFI surface. The WASM exports have JavaScript-friendly names — `verifyChainJson`, `verifyAttestationJson`, `verifyArtifactSignature` — meaning a browser, a CI runner, or a VS Code extension can verify a signature with no native dependencies and no network calls. The FFI side exposes `extern "C"` functions like `ffi_verify_chain_json` that hand a `VerificationReport` back across the boundary as JSON, so an iOS or Android app — or a git hook written in anything — can link the verifier directly. + +This is the structural inversion that makes the "no server" claim real. In Sigstore's model, verification ultimately reaches back toward a transparency log; trust has a network dependency. In Auths, *verification is a pure function.* Give it the attestation bytes and a root key and it returns Valid, Expired, Revoked, InvalidSignature, or BrokenChain — offline, deterministically, in a sandbox. The trust root is something you pin once, not something you phone home to. + +## Pairing: the ceremony that became two steps + +For all its cryptographic seriousness, the part of Auths that will decide whether anyone *uses* it is mundane: adding a second device. This is where decentralized-identity projects usually go to die, drowning in QR-code ceremonies and seed-phrase rituals that normal humans abandon. + +The git log tells a story of ruthless simplification here — one commit literally reads *"simplify pairing and rotation steps from 7 steps to 2,"* another *"strip ceremony to one-line confirm."* The current flow: on your laptop you run `auths pair`. It generates an ephemeral P-256 key, spins up a tiny HTTP server bound to your LAN, and prints a QR code plus a six-character short code (drawn from a base32 alphabet with the confusable characters — `0`, `O`, `I`, `L`, `1` — removed). On your phone, you scan or type the code, and the devices complete an Elliptic-Curve Diffie-Hellman handshake over the local network. The QR code carries an `auths://pair?...` URI packing the controller DID, the endpoint, the ephemeral key, the session ID, the short code, an expiry, and the requested capabilities. + +The interesting design judgment is what they did with the **SAS** — the Short Authentication String, a ten-byte value derived from the shared ECDH secret that protects against a man-in-the-middle. The SAS renders two ways: as six emoji (for visual recognition) and as an authoritative seven-digit number. The maximalist version of this UX forces you to compare the codes on both screens, every time. Auths *prints* the SAS but, by default, doesn't block on it — treating the QR scan as the authenticated out-of-band channel, exactly the way Signal and WhatsApp treat safety numbers as opt-in. Only `auths pair --verify` reinstates the mandatory comparison, for users pairing across a network they don't trust. It's the correct call: security that gets switched off because it's annoying provides no security, and the people who genuinely need MITM protection are a flag away from getting it. + +## The honest part: where this thing is breakable + +A credible technical assessment names the sharp edges, and to its considerable credit, *Auths names them itself.* There is a document in the repo, `multi_device_accepted_risks.md`, that reads less like marketing and more like a flight-incident report. This is the most trustworthy thing about the project, and it's worth taking seriously. + +**The duplicity fork.** The shared identity KEL — the log that enumerates all your devices — currently runs with a key threshold of one (`kt=1`). Any single device can sign a rotation. With no witness infrastructure to order events, two of your devices can each author a *different* valid rotation at the same sequence number, and the log forks — permanently. There is no automatic winner. The system's defense is detection, not prevention: a `detect_duplicity()` function scans the events, groups them by `(prefix, sequence)`, and returns `DuplicityReport::Diverging` with the conflicting SAIDs the moment it sees two different events claiming the same slot. The policy is explicitly *fail-open* — a forked shared KEL raises a warning but does not, by itself, invalidate an otherwise-valid signature. Recovery is manual: you run `auths device remove` on the device you trust. This is a real, unmitigated gap, and the docs say so in plain language. + +**No witnesses, no global ordering.** A verifier trusts the first valid event it sees locally. There is no network-wide source of truth about which rotation came first. The blast radius is bounded — each device replicates the full shared KEL, so the universe of conflicting claims is your own devices rather than the entire internet — but "trust what you saw first" is a weaker ordering guarantee than a transparency log provides, and it's fair to call it that. + +**The interop gap.** Remember that careful, byte-ordered, KERI-compatible SAID computation? The same risk doc catalogs, with disarming honesty, a list of places where the current wire format diverges from the ToIP KERI v1.1 spec — an in-body timestamp field that leaks into the SAID, a mobile FFI struct that duplicates the event type with an in-body signature, and the use of the `1AAI` CESR code (technically the *non-transferable* P-256 verkey code) for transferable identities. The conclusion the authors draw themselves: "Internally consistent; cross-implementation interop with KERIpy / KERIox / Signify is currently broken." So the KERI compatibility that justified all that byte-ordering care is, today, aspirational. That's a meaningful gap between the design's ambition and its current state, and pretending otherwise would be dishonest. + +**The bootstrap problem.** And underneath all of it sits the question no decentralized identity system fully escapes: the first time you encounter a `did:keri:E...`, why should you trust it? Auths can prove an identity is *internally consistent* — that the log is unbroken, the signatures check, the chain is intact. It cannot, by itself, tell you that this identity belongs to the human you think it does. That binding has to come from somewhere external: a verified commit on a public repo, an out-of-band exchange, an organization's published roster. This isn't a bug specific to Auths — it's the irreducible core of the trust-establishment problem — but it's the work that remains after the cryptography is done. + +The good news is that the *fix* for the worst of these is already designed. The roadmap to eliminate the duplicity fork is multi-signature thresholds: move the shared KEL from `kt=1` to `m`-of-`n`, and the race vanishes by construction, because no single device can produce a rotation that satisfies the threshold alone. Two devices can no longer fork the log because neither one, acting alone, can advance it. The pieces — dual-index CESR signatures, threshold-aware validators, a partial-signing UX — are specced. Whether they ship is, candidly, the question that determines if this is a research toy or an industry primitive. + +## The market: a real and rising tide + +Now the part the skeptics undersell. It is easy to look at a pre-launch project with a duplicity bug and a broken interop story and wave it off. It is harder to look at the market it's aimed at, because that market is large, growing fast, and structurally unsettled in exactly the way that rewards a clean new primitive. + +Start with the obvious envelope. The software supply chain security market sat around USD 2.16 billion in 2025 and is tracking toward roughly USD 3.8 billion by 2032 at a low-teens CAGR; broader platform definitions put it at USD 5.53 billion in 2025, heading to USD 10.1 billion by 2030. These are healthy, double-digit growth markets — but they're not the whole prize, because Auths isn't only a supply-chain tool. It's a developer-identity primitive, and the decentralized-identity market is on a different curve entirely: estimates cluster around USD 5–7 billion in 2026 and project past USD 50 billion by the early 2030s at CAGRs north of 50%, pulled forward by regulation like the EU's eIDAS 2.0 wallet mandate. Auths sits in the overlap of these two waves — supply-chain integrity *and* decentralized identity — which is the most attractive real estate a young primitive can occupy. + +And the *demand signal* underneath the analyst numbers is concrete, not speculative. npm's Sigstore-powered provenance went generally available and, by the numbers, over 16,000 unique packages now publish with provenance, and provenance-enabled versions have crossed hundreds of millions of downloads. That matters enormously for Auths — not as competition, but as *proof of appetite.* Sigstore did the expensive cultural work of convincing the JavaScript ecosystem that signed provenance is normal and good. A few years ago, "every package should carry a cryptographic provenance attestation" was a security researcher's dream. Today it's a default in the world's largest package registry. The behavior Auths needs already exists in developers' hands. + +The regulatory picture is genuinely interesting rather than simply tailwind-shaped. The Biden-era executive orders (14028, then 14144) drove SBOM and signing mandates hard; the 2025–2026 OMB memoranda walked the prescriptive mandates back toward a "risk-based approach," letting agencies choose their own controls. Read pessimistically, that's softening regulatory pressure. Read the way a builder should, it's *better* for a tool like Auths: a world that demands cryptographic provenance but doesn't dictate the *mechanism* is a world where the simplest, cheapest, most operationally trivial mechanism wins on merits rather than on a compliance checkbox. Mandates favor incumbents with compliance teams. Open competition on cost and ergonomics favors whoever has the lowest-friction primitive. SLSA adoption, meanwhile, keeps climbing on its own momentum — Docker's Hardened Images ship SLSA Level 3 provenance by default — which means the *concept* of build-and-identity provenance is being normalized by the biggest names in the ecosystem regardless of which administration holds the pen. + +Put the pieces together and the market thesis is neither hype nor hand-waving. The behavior is proven (16,000 packages signing today). The budgets are real and compounding (two overlapping markets, both double-digit-or-better growth). The regulatory environment has shifted from *mandate-driven* to *merit-driven*, which favors the low-friction challenger. And the total addressable population isn't "enterprises that buy security platforms" — it's *every developer who makes a Git commit*, which is the largest identity market that has ever existed and one that no incumbent has cleanly captured. + +## How you actually unseat the incumbents + +Disruption stories are usually told as feature-versus-feature. The real ones are almost always *cost-structure* stories, and that's where Auths has its sharpest argument. + +Sigstore's keyless model is genuinely excellent, and its great strength — no long-lived keys — is purchased with a permanent operational liability: Fulcio and Rekor are services that must run, scale, and stay honest in perpetuity. The public-good instances are heroically maintained by the OpenSSF and a handful of sponsors, but the moment you want your *own* trust root — a private enterprise that doesn't want its internal release graph in a public transparency log — you are now operating CA and transparency-log infrastructure yourself. That's a team, a budget, an on-call rotation, a thing that can go down. + +Auths's structural bet is that *zero infrastructure beats elegant infrastructure* for a very large slice of users. There is no service to run because the substrate — Git — is already running everywhere, already replicated, already backed up, already understood by every developer alive. The verifier is a pure WASM function with no network dependency. An enterprise that wants a private trust root doesn't deploy anything; it pins a root public key. This is the classic disruption shape: arrive *underneath* the incumbent with something that looks like a toy (no transparency log? no global ordering?), serve the users the incumbent's complexity priced out (the team that wants signed commits but will never stand up Fulcio), and climb. The multi-sig threshold work is the climb — the feature that lets it move from "signed commits for individuals and small teams" up into the high-assurance, can't-fork, recover-from-a-stolen-laptop territory where the serious money is. + +Against GPG, the contest isn't even close: GPG's failure was never cryptographic, it was ergonomic, and a two-step pairing flow with emoji safety numbers is from a different century of usability. Against raw SSH signing, Auths offers what SSH lacks — rotation history, delegation chains, revocation, and capability scoping — without asking the user to hand-manage `allowed_signers`. And against blockchain identity systems (ENS, `did:ion`, the whole on-chain DID menagerie), the pitch is that it delivers the decentralization those systems promise without the gas fees, the latency, the consensus layer, or the requirement that the planet agree on a single ledger. You don't need the world to agree on an ordering if your trust roots are pinned and your verification is local. + +## The one bet that decides everything + +Strip away the cryptographic craftsmanship — the pre-rotation, the self-addressing identifiers, the dual-signed chains, the embeddable verifier — and Auths comes down to a single wager about where the root of trust should live. The incumbents say it lives in infrastructure: in a CA you federate, a log you append to, a chain you reach consensus on. Auths says it lives in a place developers already trust with the entire history of everything they've ever built — the repository itself. + +The weaknesses are real and the authors, refreshingly, refuse to hide them. The `kt=1` fork is a live wound. The KERI interop is currently broken. The bootstrap problem is unsolved, as it is everywhere. But these are the weaknesses of a project that has made its hard architectural choices and is executing against a clear-eyed list, not the vagueness of a project that hasn't figured out what it is. The threshold-signature upgrade is the hinge: ship it, and the most dangerous gap closes by construction, and the "just Git and cryptography" pitch acquires the high-assurance teeth it needs to climb upmarket. + +The supply-chain attacks aren't slowing down. The budgets are compounding. The behavior — sign your code, prove who you are — has already gone mainstream on the back of Sigstore's cultural groundwork. The open question was never whether developers would accept cryptographic identity. `xz` settled that. The open question is what it will cost them to adopt it. Auths's answer is the most aggressive one on the table: *nothing you don't already run.* If that holds up under the weight of the threshold work, the root of trust may turn out to have been sitting in `~/.git` the entire time, waiting for someone to notice. + +--- + +## Sources + +- Verified Market Research — Software Supply Chain Security Market: https://www.verifiedmarketresearch.com/product/software-supply-chain-security-market/ +- Mordor Intelligence — Software Supply Chain Security Platforms Market: https://www.mordorintelligence.com/industry-reports/software-supply-chain-security-platforms-market +- Mordor Intelligence — Decentralized Identity Market: https://www.mordorintelligence.com/industry-reports/decentralized-identity-market +- Sigstore Blog — npm provenance goes GA: https://blog.sigstore.dev/npm-provenance-ga/ +- AquilaX — Software Supply Chain Security Beyond SBOMs (Sigstore, SLSA, provenance): https://aquilax.ai/blog/supply-chain-artifact-signing-slsa +- Dark Reading — Trump Administration Rescinds Biden-Era SBOM Guidance: https://www.darkreading.com/application-security/trump-administration-rescinds-biden-era-sbom-guidance diff --git a/docs/getting-started/credentials.md b/docs/getting-started/credentials.md new file mode 100644 index 00000000..dd1dd85f --- /dev/null +++ b/docs/getting-started/credentials.md @@ -0,0 +1,179 @@ +# Capability credentials + +How a capability or role becomes a **verifiable credential** — issued by one KERI +identity to another, revocable per-credential, and honored only when the holder proves +they control the subject identity.

The correct cesride-backed `CesrV1Codec` (`src/codec.rs`: +`encode_pubkey`/`encode_digest`/`decode_qualified`) exists but is gated behind the **optional `cesr` +feature** (`default = []`) and used only for "CESR export". keripy rejects our events; our SAID +`EEpOF…` ≠ keripy's `EBKTh…`; our verkey `DAAEC…` ≠ keripy's `DAAB…`. + +**Proven fix (committed `9354fba`):** the test `codec::tests::cesr_primitives_match_keripy_reference` +shows **cesride 0.6 == keripy 1.3.4** byte-for-byte (`encode_pubkey(bytes(0..32),Ed25519)` → +`DAABAgMEBQYHCAkKCwwNDg8QERITFBUWFxgZGhscHR4f`; `encode_digest(blake3(verkey.qb64b))` → +`EF_M_u7ASVHXfI8QzdWLq3V9ocSKqxkbujXGbi9QMtP9`).

The sdk rotation path + now USES its previously-ignored `new_next_curve`; the verify path uses `ParsedKey.seed.curve()`. +- `2ad5cd0` — **Part 2a (digests):** `compute_said` + `compute_next_commitment` use the cesride + digest. **keripy SAID byte-interop is PROVEN** — `KERIPY_INTEROP=1 cargo nextest run -p auths-keri + -E 'test(subprocess_mode_when_keripy_available)'` goes FAIL→PASS. 1458 tests pass: the suite + *computes* SAIDs rather than hardcoding them, so the value change was non-breaking (the feared + atomic fixture-regen mostly evaporated). + +**DONE — Part 2b (verkey `k[]` encoding) [uncommitted; ready for the user to commit].** Verkeys are +now valid CESR `qb64` (cesride), byte-identical to keripy, so keripy can decode `k[]` for signature +checks.

Written so any fresh reader (human or LLM) can pick up cold. + +## What this document is + +This is the implementation plan for **Stage 1 of the multi-device design ladder**. The architectural motivation lives in `/Users/bordumb/workspace/repositories/auths-base/essays/design/multi_device.md` — read that first if you're new to the problem; it has diagrams, decision-axis tables, and a market-comparison section against OAuth Device Grant and WebAuthn. This document skips the "why" and focuses on the "what to do and where." + +The goal is to replace the current asymmetric one-KEL-with-device-subjects model with a symmetric one where every device has its own `did:keri:` KEL and the user's identity is a shared KEL whose controllers are the devices. Stage 1 stops short of witness infrastructure — the security boundary at this stage is Secure Enclave + biometric on each device. Witnesses arrive in Stage 2; see the design doc for the full ladder. + +## TL;DR for a fresh reader + +- **Today**: Mac holds the single controller KEL. Phone is a subject (`did:key:` derived from its SE pubkey). Rotation uses a `supersedes_attestation_rid` pointer. Works for Mac→phone, broken for phone→new-Mac (stolen-laptop case). +- **Stage 1 target**: Every device runs its own KEL with pre-rotation. A separate shared identity KEL (`did:keri:You`) lists both devices as controllers, `kt = 1`. Pairing = `rot` on the shared KEL adding a controller. Device rotation = `rot` on the device's own KEL. Stolen-laptop recovery = surviving device signs a `rot` on the shared KEL to swap controllers. +- **Pre-launch with zero users.** No migration. Rip out `DeviceDID` and everything that depended on it. +- **What's in Stage 1**: protocol types, storage, FFI, pair/rotate/revoke ceremonies, `DeviceDID` removal. +- **What's out of Stage 1**: witnesses, `kt ≥ 2`, OOBI discovery. Those are Stages 2–4. + +## Required reading before writing code + +1. **`/Users/bordumb/workspace/repositories/auths-base/essays/design/multi_device.md`** — the architectural context. Key sections: "Option B — Multi-sig controller over a shared identity KEL," "Market comparison," "Direction of travel — incremental upgrade ladder." The Stage 1 section of that doc is the source of truth for the target; this plan operationalizes it. +2. **`/Users/bordumb/workspace/repositories/auths-base/essays/philosophy/reply_to_isi_pre_rotation.md`** — the semantic distinction between linking (delegation), updating (rotation), and unlinking (revocation). Pre-rotation's cryptographic guarantee only applies to update. This shapes how the new code should name events and validate them. +3. **`docs/api-spec.yaml`** — current wire format for pair sessions. Stage 1 extends this; don't regress it. +4. **`/Users/bordumb/workspace/repositories/auths-base/essays/design/multi_device.md` § "What Stage 1 needs to answer before a plan is written"** — four decisions that should be resolved before detailed coding. This plan gives defaults for each; flag to the user if the defaults are wrong. + +## Hard constraints + +- **iOS Secure Enclave is P-256 only.** Non-extractable keys. Biometric-gated per use (we keep this policy). +- **Curve-agnostic code.** Enforced by `cargo run --bin xtask -- check-curve-agnostic`. No `p256::...` or `ed25519::...` imports outside `auths-crypto`, `auths-core/src/crypto`, and `auths-mobile-ffi`. Use `auths_crypto::CurveType` and `RingCryptoProvider::p256_verify` in CLI/SDK code. +- **CLI cannot import `auths_core`, `auths_id`, `auths_storage` directly.** Route through `auths_sdk::*` re-exports. Enforced by the `check-sdk-boundary` pre-commit hook. +- **No backwards-compatibility hedges.** User has confirmed pre-launch posture: remove fields and types rather than add `Option` migration shims. If a field becomes wire-required, make it required — no `#[serde(default)]` for "legacy messages." + +## Current state — surveyed files to know + +### Rust (Mac side) + +| File | What it does today | +|---|---| +| `crates/auths-verifier/src/types.rs` | `DeviceDID` (transparent String, `did:key:` form), `IdentityDID`, `CanonicalDid`, `DevicePublicKey`. | +| `crates/auths-verifier/src/core.rs` | `Attestation` struct.

There's no `did:key:` in the attestation graph. +- **`Attestation.supersedes_attestation_rid` is removed.** Rotation no longer produces a superseded attestation — it produces a `rot` event in the rotating device's own KEL. The device's DID is stable across rotations (that's exactly what pre-rotation gives us). +- **Pair and rotation ceremonies converge.** There's no separate "rotate" mode on the session layer — every "pair new thing to identity" is a `rot` on the shared KEL that adds a controller. "Rotate my keys" is a local `rot` on the device's own KEL, done without a session. + +### Wire / session protocol + +The pairing URI carries enough to bootstrap mutual verification: + +``` +auths://pair?sid=SID&sc=SHORTCODE&x=EXPIRES_AT + &did_mac=did:keri:MAC + &icp_mac=BASE64URL(MacInceptionEventJson) + &ep=BASE64URL(EndpointURL) +``` + +The phone scans, verifies Mac's inception event self-consistency, sends its own inception event back. Mac verifies. Both sign a `rot` on the shared KEL to add the other as a controller. For the *very first pair* (no shared KEL yet), the initiating side inceptions the shared KEL first; the `rot` that adds the second device follows immediately in the same flow. + +### Storage + +On Mac (`~/.auths/`): +- The Mac's own device KEL (independent, non-shared). +- The shared identity KEL (replicated state). +- Encrypted keychain entries for Mac's device key + pre-rotation key AND for Mac's signing participation in the shared KEL (the "my piece of the shared identity" key). + +On iPhone: +- The phone's own device KEL (SE-backed; already exists). +- The shared identity KEL (replicated state, stored in iOS Keychain). +- The phone's SE bootstrap key is the phone's identity-key material; no separate "controller key" at this stage. + +### Ceremonies (end state) + +- **`auths init` on a fresh Mac**: create Mac's own device KEL. No shared KEL yet — that gets born at first pair. +- **First-ever `auths pair` between Mac and phone**: + - Phone already has its own device KEL from first-launch bootstrap. + - Mac has its own device KEL from `auths init`. + - Pair ceremony: mutual verification of inception events → Mac signs `icp` for shared KEL with itself + phone as co-controllers → shared KEL replicated to phone. +- **Subsequent `auths pair` on Mac with a second phone**: + - Mac has own KEL + shared KEL with phone_A as co-controller. + - Phone_B runs for the first time, creates own KEL. + - Pair ceremony: Mac (or phone_A — any controller can do it at `kt=1`) signs a `rot` on the shared KEL adding phone_B as a controller. +- **Rotating a device's own keys**: local `rot` on that device's KEL. No session, no ceremony. Pre-rotation is revealed, new pre-rotation is committed. Other devices re-learn on their next verify. +- **Removing a device**: any controller signs a `rot` on the shared KEL dropping the target device from the controller set. `auths device remove ` on Mac, or Settings → Devices → Remove on phone. +- **Stolen-laptop recovery**: phone (the surviving controller) signs a `rot` on the shared KEL that removes the lost Mac's `did:keri:` and adds a new Mac's `did:keri:`. Done via `auths pair --recover` on the new Mac + confirmation on phone. + +## Open questions (defaults provided; flag if wrong) + +1. **Storage layout on Mac.** Default: both the device KEL and the shared KEL live under `~/.auths/`, separate refs (`refs/auths/device-kel/*` vs `refs/auths/shared-kel/*`). Reusable from `auths-id/src/storage/git_refs.rs`. +2. **Storage on iPhone.** Default: extend `IdentityStorage` to hold both the phone's own KEL state and the shared KEL state. Persist to iOS Keychain as JSON blobs. Two separate Keychain items: `dev.auths.device-kel.v1` and `dev.auths.shared-kel.v1`. +3. **Pair URI shape.** Default: the Mac's QR carries `did_mac + icp_mac` (its own KEL's inception). The phone sends back its `did_phone + icp_phone` via the existing `/v1/pairing/sessions/{id}/response` body. The existing `SubmitResponseRequest` gains fields `initiator_inception_event`, `responder_inception_event`. If pair-is-first-pair, one side also includes `shared_kel_inception` on the next POST. +4. **kt=1 with cross-device coordination.** At `kt=1` any single controller can sign. Initiating device signs the `rot` that adds the new device. No co-signing in Stage 1. +5. **Attestation layer.** Kept. Attestations are still the mechanism for "this identity grants capability X to this device" (distinct from controllership). A device can be a controller of the shared KEL and separately hold one or more attestations for specific capabilities. +6. **Name scheme for `did:keri:You`.** The SAID (self-addressing identifier) of the shared KEL's inception event. Deterministic from the inception content; no user-picked name. +7. **Who inceptions the shared KEL first?** The Mac. When `auths pair` is invoked and no shared KEL exists yet, the Mac creates the `icp` event locally, signs it with its device key, the phone receives and verifies it, then the `rot` adding the phone lands immediately. Alternative: the first-invoked device (could be phone). Default is Mac for implementation simplicity — the Mac already has KEL-management machinery in `auths-id`. +8. **Revocation of the lost device.** When replacing a stolen Mac, the surviving phone issues `rot` on shared KEL with `OldMac` removed, `NewMac` added. `OldMac`'s device KEL continues to exist (we can't stop it); the shared KEL no longer lists it as a controller, which is sufficient — verifiers trust the current controller set, not the historical one. + +## Implementation plan — chunks + +Each chunk is scoped to a single reviewable piece. Run `cargo check --workspace --all-targets && cargo clippy --workspace --all-targets && cargo test --workspace --lib && cargo run --bin xtask -- check-curve-agnostic` after every chunk. The `auths pair` end-to-end test (Mac + real iPhone) should be re-run after Chunks 5 and 6. + +### Chunk 1 — Protocol types (wire-format foundation) + +Update `crates/auths-pairing-protocol/src/types.rs`: + +- Remove `SessionMode` entirely (pair/rotate-mode distinction goes away — pair is just "add a controller to the shared KEL"). +- Remove `SubmitResponseRequest.new_device_signing_pubkey` (rotation-specific field; no longer needed). +- Add `initiator_inception_event: String` and `responder_inception_event: String` fields to `SubmitResponseRequest` (base64url-no-pad JSON blobs of each side's `icp` event from their own device KEL). +- Add a new message type `SharedKelSetupRequest { icp_event: String }` carried on a new endpoint (or inlined into `/response` conditionally when no shared KEL exists yet). +- Update `docs/api-spec.yaml` in the same PR (ADR 004 requirement). +- Regenerate schemas: `cargo run --bin xtask -- generate-schemas`. + +Verification: `cargo test --workspace --lib` green; the `spec-drift` pre-commit gate is green. + +### Chunk 2 — Rust-side storage for device + shared KELs + +New / modified files: +- `crates/auths-id/src/keri/device_kel.rs` (new): thin wrapper around existing KEL-creation logic that names the resulting entity a "device" for clarity. Reuses `create_keri_identity_with_curve`. Storage goes under `refs/auths/device-kel/{prefix}/*`. +- `crates/auths-id/src/keri/shared_kel.rs` (new): shared-KEL operations — inception with multiple controllers, `rot` to add/remove controllers. `kt=1` hardcoded for Stage 1 (flag TODO for `kt` upgrade path). Storage under `refs/auths/shared-kel/{prefix}/*`. +- `crates/auths-id/src/storage/git_refs.rs`: add path constants for the two new ref namespaces. +- `crates/auths-id/src/identity/initialize.rs`: refactor to call the new `device_kel::create` + remove attestation-based initialization. + +The existing `create_keri_identity_with_curve` and `initialize_registry_identity` code paths provide 90% of what's needed; we're renaming and splitting, not rewriting. + +Verification: new unit tests in `crates/auths-id/tests/` covering device-KEL inception, shared-KEL inception, and `rot`-add-controller with kt=1. + +### Chunk 3 — Mobile FFI extensions + +In `crates/auths-mobile-ffi/src/`: +- Rename `identity_context.rs` → `device_kel_context.rs`. Its existing `createIdentity` becomes the phone's device-KEL inception (which is what it structurally already is). +- New `shared_kel_context.rs`: FFI entry points for shared-KEL operations. `build_shared_kel_inception_payload(device_kel_didkeri, peer_didkeri) -> SignatureRequest`, `assemble_shared_kel_inception(signatures) -> SharedKelEvent`. Similar two-step for rotations. +- Remove `pairing_context.rs` rotation helpers (`build_rotation_binding_message`, `assemble_rotation_response_body`). Replaced by shared-KEL ops. +- Update `lib.rs` exports. +- Regenerate Swift bindings: `just build-xcframework` in the `auths-mobile/` repo. + +Verification: `cargo check -p auths-mobile-ffi` green; `just build-xcframework` succeeds; resulting `auths_mobile_ffi.swift` includes the new functions. + +### Chunk 4 — CLI rewrite for pair / rotate / revoke + +Files to rewrite: +- `crates/auths-cli/src/commands/device/pair/lan.rs`: replace current pair-then-attest flow with pair-then-rot-shared-KEL. +- `crates/auths-cli/src/commands/device/pair/common.rs`: replace `handle_pairing_response` with `handle_pair_response` that does mutual inception verification + shared-KEL `rot`. +- **DELETE** `crates/auths-cli/src/commands/device/pair/rotate.rs`. Its purpose is gone — native KEL rotation doesn't need a session. +- Remove `--rotate` flag from `PairCommand` in `mod.rs`. +- Add `auths identity rotate` command that calls `auths-id/src/identity/rotate.rs` on the caller's own device KEL (no session, no ceremony — just local key rotation with pre-rotation reveal). +- Add `auths device remove ` command that signs a `rot` on the shared KEL dropping the named controller. + +Verification: `auths init` then `auths pair` on Mac + `PairDeviceView` scan on iPhone → shared KEL created with both as controllers. `auths identity rotate` on Mac → Mac's device KEL rotates, shared KEL unchanged. `auths device remove` → target dropped from controller set. + +### Chunk 5 — iOS Swift rewrite for pair / rotate / revoke + +Files: +- `/Users/bordumb/workspace/repositories/auths-base/auths-mobile/ios/Auths/Services/DeviceDIDBootstrap.swift`: rename / refactor. It's no longer a "bootstrap DID" — it's the phone's device KEL. Keep the SE key management but delete the rotation scaffolding (`beginRotation`, `commitRotation`, `rollbackRotation`, `signWithOldKey`, `BootstrapKeyVersion`). Rotation is now a `rot` event on the phone's own KEL via FFI, not a staged-key dance. +- `/Users/bordumb/workspace/repositories/auths-base/auths-mobile/ios/Auths/Services/PairingService.swift`: rewrite `completePairing` to do mutual inception verification + participate in shared KEL `rot`. Delete `rotateKey`. +- `/Users/bordumb/workspace/repositories/auths-base/auths-mobile/ios/Auths/Views/RotateKeyView.swift`: **DELETE**. Rotation is a settings action on the phone's own KEL, not a multi-device ceremony. Replace with a simpler Settings → Advanced → "Rotate signing key" button that triggers a local FFI call. +- `/Users/bordumb/workspace/repositories/auths-base/auths-mobile/ios/Auths/Views/CreateIdentityView.swift`: unchanged conceptually — still creates the phone's own KEL at first launch. The `IdentityStorage` struct gets new fields for shared-KEL state. +- `/Users/bordumb/workspace/repositories/auths-base/auths-mobile/ios/Auths/Views/IdentityView.swift`: update to display the shared identity DID and the controller set. +- `/Users/bordumb/workspace/repositories/auths-base/auths-mobile/ios/Auths/Views/DevicesView.swift`: "Remove" action per device — calls into a new `SharedKELService` that signs a `rot` on the shared KEL via FFI. +- Add `/Users/bordumb/workspace/repositories/auths-base/auths-mobile/ios/Auths/Views/Settings/ForgetIdentityView.swift`: the "nuclear reset" — wipes the phone's device KEL and shared-KEL copy, returns to onboarding. + +Verification: end-to-end on real iPhone — pair, rotate locally, remove-device, forget-identity — all complete cleanly. + +### Chunk 6 — Delete `DeviceDID` and dead code + +Now that nothing consumes `DeviceDID` in production: + +- `crates/auths-verifier/src/types.rs`: delete `DeviceDID` type, `from_public_key` for device DIDs, `ref_name`, `matches_sanitized_ref`, `signer_hex_to_did`. +- Delete the multicodec prefix machinery (0xED 0x01 for Ed25519, 0x80 0x24 for P-256) since we're not deriving `did:key:` anymore. +- `crates/auths-verifier/src/core.rs`: `Attestation.subject` changes to `CanonicalDid`, but `supersedes_attestation_rid` gets deleted (rotation no longer produces superseded attestations). +- `crates/auths-id/src/attestation/create.rs`: delete `create_superseding_attestation`. +- `crates/auths-storage/src/git/attestation_adapter.rs`: update ref paths from `did_key_z…` sanitized form to `did_keri_E…` sanitized form. Storage is keyed by `did:keri:` now. +- Audit the workspace for lingering `DeviceDID` references: `rg -w DeviceDID crates/ packages/` — should return zero after this chunk. + +Regenerate schemas, update `docs/api-spec.yaml` for the removed `new_device_signing_pubkey` and `supersedes_attestation_rid` fields. + +Verification: workspace-wide `cargo check --all-targets` + `cargo test --workspace --lib` + `cargo clippy --workspace --all-targets` + `cargo run --bin xtask -- check-curve-agnostic` + `cargo run --bin xtask -- generate-schemas` (producing zero diff if schemas already match). + +### Chunk 7 — Attestation reshape + +With `DeviceDID` gone and no subject surrogate, decide what attestations are *for* in Stage 1: + +- **Controllership is tracked by the shared KEL.** Adding/removing a device is a `rot`, not an attestation. +- **Capabilities** (`sign_commit`, etc.) are still meaningful as attestations issued by `did:keri:You` (the shared identity) against a specific controller device's `did:keri:`. +- **Git-commit attestations** stay as before — the commit-signer is a controller of the identity, not the identity itself. + +Stage 1 work: make sure `Attestation.subject = did:keri:…` works end-to-end for capability attestations, and that the storage layer indexes correctly. + +### Chunk 8 — Verifier audit + +Walk `crates/auths-verifier/src/verify.rs` and cross-check: +- Verifying an attestation now requires resolving a `did:keri:` subject to its KEL and checking the signing key is a current key in that KEL. +- Verifying a KEL event walks the `icp`/`rot`/`ixn` chain and validates each against the prior state. +- The shared KEL's `rot` events are verified against their prior controller set + `kt`. + +Add integration tests that simulate a full pair + rotate + remove flow and verify every resulting attestation under the new verifier path. + +### Chunk 9 — UX polish + verification + +- `auths status` updated to show shared-KEL current state (controllers, `kt`, `nt`). +- iOS `IdentityView` shows shared-KEL DID + controller list + `kt` value. +- End-to-end tested on real iPhone + Mac: + - Fresh `auths init` + first pair. + - Pair a second phone. + - Rotate Mac's keys locally (`auths identity rotate`). + - Remove a paired device. + - Stolen-laptop recovery: `auths pair --recover` on new Mac + phone confirms. + - Forget identity on phone (wipes its device KEL + shared-KEL copy). + +## Verification summary + +At the end of Stage 1, the full check matrix should pass: + +```bash +cd /Users/bordumb/workspace/repositories/auths-base/auths +cargo check --workspace --all-targets +cargo clippy --workspace --all-targets +cargo test --workspace --lib +cargo run --bin xtask -- check-curve-agnostic +cargo run --bin xtask -- generate-schemas # should produce no diff +cargo run --bin xtask -- validate-schemas +``` + +Plus in the `packages/` subworkspaces: + +```bash +cd packages/auths-node && cargo clippy --all-targets +cd packages/auths-python && cargo clippy --all-targets +``` + +Plus the pre-commit hooks: cargo fmt, SDK boundary, spec drift gate, schema validation. + +End-to-end tests on device: covered in Chunk 9's checklist. + +## Things deliberately NOT in Stage 1 + +- **Witnesses of any kind.** Neither Rekor-as-anchor (Stage 2a) nor KERI-native witnesses (Stage 2b). The shared KEL is unanchored; dispute resolution relies on "whichever valid `rot` reaches a given verifier first" and on Secure Enclave hardness. This is the honest Stage 1 tradeoff; don't paper over it. +- **`kt ≥ 2`.** Stage 3. With kt=1, any controller can solo-rotate. Lock-out risk = zero; single-device-compromise blast radius = full. Accepted tradeoff at this scope. +- **OOBI discovery.** Not needed when the shared KEL's full replica lives on every controller device. Stage 2b adds OOBI when witnesses arrive. +- **Multi-hop supersedes / history crawling.** Gone with `supersedes_attestation_rid`. Rotation history is in the device's own KEL `s` sequence. +- **External identity federation.** `did:keri:You` is stable but we're not yet publishing it to any federation or third-party RP. That's downstream of witnesses. + +## Developer migration + +Pre-launch means pre-launch — there is no back-compat shim and no auto-migration tool.

The ref-sanitization scheme is also canonicalized on this branch (single function `sanitize_did` replacing the two ad-hoc variants previously scattered around the repo), so any ref-name tooling that crawled the old layout needs to be re-run after reinitialization. + +Git commit trailers also change format: `Auths-Signer: did:key:z…` becomes `Auths-Signer: did:keri:E…` once attestation subjects flip to the new DID type. Old signed commits do not verify after the type flip. + +## Handoff notes for a fresh LLM + +If you're picking this up cold: + +1. Read the two essays mentioned in "Required reading" above. They give you the architectural and historical context this plan skips. +2. Before writing any code, run `git log --oneline -20` on the `auths/` repo to see what landed in the rotation UX polish session (immediately prior work). That rotation work is what Chunk 6 mostly deletes. +3. The user has explicit "rip out, no back-compat" posture. Do not add `Option` wrappers for fields that become wire-required — make them required. Do not leave deprecation shims for `DeviceDID`. Delete outright. +4. The user wants pre-commit hooks to pass cleanly. If you hit a gate, fix it in the same chunk; don't leave it for later chunks to clean up. +5. When in doubt on an open question (the 8 above), ask the user — don't silently pick. Defaults above are reasonable but not committed. +6. Work chunk by chunk. Do not interleave multiple chunks — they depend on each other. +7.

Per CESR, `1AAI` is non-transferable and `1AAJ` is the transferable P-256 verkey code; Auths identities rotate, so `1AAJ` is correct.

What done looks like. +- **Closes.** Which `keri_compliance.md` findings or accepted-risks items this epic resolves. Quote IDs. +- **Prerequisites.** Which other epics must land first. +- **Subtasks**, each with: + - A short rationale (why this change, in one or two sentences). + - The specific file(s) and (when known) line ranges that change. + - A **code snippet** showing the actual change. Before/after where the contrast is informative; just "after" otherwise. Snippets must be valid Rust that would compile in context (modulo `...` elisions). + - An individual estimate in eng-days. +- **Verification.** How you'll know the epic is done. Concrete test names, CI gates, or fixture round-trips — never vague. +- **Epic total estimate.** + +### 3.3 Required epics + +At minimum, your plan must include epics covering: + +- **Epic A: Spec-compliance wire-format fixes.** Closes all CRITICAL and MAJOR findings in `keri_compliance.md`. Maps to Epic 4 in `multi_device_accepted_risks.md`. **This is P0 — sequenced first.** +- **Epic B: Dual-index CESR signatures + true removal.** Supplements Epic 1 in the existing roadmap. Your version should refine the existing spec with concrete code. +- **Epic C: Multi-sig threshold upgrade (`kt ≥ m` of `n`).** Supplements Epic 2 in the existing roadmap. +- **Epic D: Witness infrastructure (minimum viable for launch).** Supplements Epic 3. Scope down to "one Auths-operated witness with the architecture to add more later" — do not try to land full multi-witness diversity at launch. +- **Epic E: Crypto provider trait completion + dependency hardening.** Covers the cross-cutting items in `prompt.md § 5`: `sign_p256` trait method, `rand::random` replacement, `cargo deny` in CI, exact-pin crypto deps, Rekor trust-root decision. +- **Epic F: Backup, recovery, and durability.** `auths backup export/import`, Git GC disable on init, `auths sync` as a first-class command, pre-rotation seed escrow on co-controllers. +- **Epic G: Agent delegation as the headline feature.** Distinct from commit signing. Includes the verifier-side scope-down logic and an end-to-end demo. +- **Epic H: Scope consolidation + cross-impl interop CI gate.** Consolidate the workspace (32 crates → ~12, per `critique.md`).

Self-check before declaring complete. + +### 4.1 Compliance with strategic posture + +- [ ] No epic proposes forking the KERI wire format. +- [ ] No epic proposes renaming `did:keri:` to anything else. +- [ ] No epic proposes replacing Blake3 with SHA-256 (or vice versa) on a non-compliance basis. +- [ ] No epic proposes dropping CESR, dropping witnesses, or dropping multi-sig. +- [ ] No epic proposes adding `Utc::now()` to domain code. +- [ ] No epic proposes adding a Rekor / Sigstore submission crate. (`auths-infra-rekor` is to be deleted, not enhanced. Users submit via `cosign` / `rekor-cli`.) +- [ ] No epic proposes a `kt=1` shared identity in any production path. + +### 4.2 Concreteness + +- [ ] Every subtask names specific files (e.g., `crates/auths-keri/src/validate.rs:766-797`). +- [ ] Every code snippet is realistic — types, function signatures, and crate imports match what's in the codebase today. +- [ ] Every estimate is in eng-days for a subtask, eng-weeks for an epic. No vague ranges. +- [ ] Every verification criterion names a concrete test or fixture, not "tests pass." + +### 4.3 Sequencing + +- [ ] Epic A (spec compliance) lands before Epic B (which depends on the dual-index work). +- [ ] Epic B lands before Epic C (multi-sig needs dual-index sigs). +- [ ] Epic D (witnesses) sequences after Epic C — without multi-sig, witnesses ratify a kt=1 race winner rather than a true threshold-met event. +- [ ] Epic E (crypto trait + deps) is parallel-safe with Epic A. Show in the critical-path diagram. +- [ ] Epic F (backup) is parallel-safe with Epic A but must not block launch. +- [ ] Epic G (agent delegation) depends on Epic A landing (the event model must be stable). +- [ ] Epic H (scope consolidation + CI gate) runs throughout; cross-impl CI gate must be live before Epic A is declared complete. + +### 4.4 Spec-traceability + +- [ ] Every Epic A subtask quotes the `keri_compliance.md` finding ID it closes (F-01, F-04, F-06, F-10, F-13, F-14, F-15, F-16, F-19, F-32, etc.). +- [ ] Every wire-format-touching subtask references the relevant section of ToIP KERI v1.1 by section number. + +### 4.5 User-preference compliance + +- [ ] No epic proposes work that requires the user to commit on your behalf. +- [ ] No epic refers to `.flow` task IDs (`fn-N.M`) in code that would land in committed files. +- [ ] Any "Out of scope" section includes a step to file a GitHub issue. +- [ ] No epic proposes intermediate `cargo build` / `cargo test` runs as the deliverable for a subtask — these are sanity checks at epic boundaries, not work products. + +--- + +## 5.

Anti-patterns to avoid + +These shape what your plan *isn't*, as much as the quality bars shape what it *is*. + +1. **Do not propose any epic whose deliverable is "documentation only."** Documentation is part of every epic; it is not an epic itself. The exception is `SPEC.md`-style work, which is a deliverable inside Epic A and Epic G. +2. **Do not propose epics that "investigate" or "evaluate."** Investigation belongs in a 0.5-day spike inside a concrete epic, not as a standalone deliverable. +3. **Do not pad estimates.** The user reads them and the 50% buffer is applied at the document level, not per task. Inflated per-task estimates compound badly. +4. **Do not write epics for code paths that should be deleted.** If `auths-mobile-ffi` should be deleted until the spec stabilizes, the epic action is "delete," not "rewrite." Same for `auths-infra-rekor`, `auths-transparency`, and any other dormant code. +5. **Do not propose backwards-compat shims, deprecation periods, or migration guides for internal code.** Pre-launch, zero users. +6. **Do not propose features that contradict the deferred list in `prompt.md § 5`.** SCIM, Radicle integration, external federation, mixed-curve controllers are out of scope. +7. **Do not invent finding IDs.** If a problem is real but not in `keri_compliance.md`, name it descriptively rather than fabricating a finding ID. +8. **Do not propose changes to the strategic posture itself.** If you believe a posture decision in `prompt.md § 4` is wrong, flag it at the *top* of your plan in a "Recommendations for the user to consider" section, but do not rewrite epics around the unaccepted change. + +--- + +## 7. First-session checklist + +Before writing the first line of `epic_plan.md`, confirm: + +- [ ] You have read `prompt.md` in full. +- [ ] You have read `CLAUDE.md`, `SECURITY.md`, `ARCHITECTURE.md`. +- [ ] You have read `docs/architecture/multi_device_accepted_risks.md` and `docs/plans/keri_compliance.md`. +- [ ] You have skimmed `docs/architecture/cryptography.md` and `docs/security/primitive-inventory.md`. +- [ ] You have run `find crates -name "*.rs" | head -50` and looked at the actual crate structure. +- [ ] You have looked at `crates/auths-keri/src/validate.rs`, `events.rs`, and `said.rs` — these are where most of Epic A's work lands. +- [ ] You have looked at `crates/auths-id/src/keri/shared_kel.rs` — this is where Epic B and C land. +- [ ] You have an explicit mapping in your notes from every CRITICAL and MAJOR `keri_compliance.md` finding to a subtask in Epic A. + +Only then begin writing `epic_plan.md`. + +--- + +## 8. How to handle ambiguity + +If you encounter a design question while planning: + +- **Spec-defined** (i.e., the answer is in ToIP KERI v1.1 or a CESR / SAID draft) — follow the spec. Quote the section number in the subtask. +- **Posture-defined** (i.e., the answer is in `prompt.md § 4` or § 8) — follow the posture. +- **Convention-defined** (i.e., the answer is in `CLAUDE.md` or `SECURITY.md`) — follow the convention. +- **Genuinely undecided** — name the question in a "Decisions deferred to implementation" subsection inside the relevant epic. Do not invent an answer; flag it so the user can decide before implementation starts. + +Common shape: "Should the new threshold validator reject `bt > |b|` strictly or allow it for forward compatibility?" — flag as decision deferred, propose the strict answer with rationale, leave room for the user to override. + +--- + +## 9. Output expectations + +The user will read `epic_plan.md` end to end. Optimize for: + +- **Skimmability:** clean headers, tables for priority and estimates, ASCII critical-path diagram. +- **Density:** no filler, no restating the prompt, no apologies. The user has read `prompt.md`; do not re-explain it. +- **Actionability:** every subtask should be picked up by an engineer who has read the prompt and the linked files, without further conversation. +- **Honesty:** if an epic is uncertain in scope, say so explicitly with the source of uncertainty. Do not paper over with confident-sounding prose. + +When you finish, end the document with a one-sentence note: "Ready for review." + +--- + +Begin by completing § 2 (Prerequisite reading).

Pre-rotation seeds escrowed on co-controllers. No `kt=1` escape hatches in production paths. +3. **Witness infrastructure that delivers KERI's convergence guarantees.** Verifiers globally agree on KEL state because witnesses ratify it. +4. **Developer experience that doesn't require knowing KERI.** `auths init`, `auths device pair`, `auths agent authorize`, `auths sign`, `auths verify`.

Each file rewards close attention; skim and you will produce confidently wrong advice. + +### Required reading (project conventions) + +1. **`CLAUDE.md`** at the repo root. This is the authoritative project guide: dependency rules, the `SDK orchestrates / Core implements` rule, error-type discipline (`thiserror` in domain, `anyhow` only at presentation boundary), the clock-injection ban on `Utc::now()`, the `unwrap_used` / `expect_used` policy. Every rule here is enforced by CI; violating one means your PR will not merge. +2. **`SECURITY.md`** at the repo root. Memory hygiene rules: `ZeroizeOnDrop` over manual `zeroize()`, no raw `Vec` for key material at module boundaries, never `Zeroizing` for keys, no synchronous blocking I/O on async threads. Read every rule. +3. **`ARCHITECTURE.md`** at the repo root. The layer diagram, dependency direction, port inventory, and bounded-context guide. Reference this when proposing where to put new code. + +### Required reading (KERI substrate) + +4. **`docs/architecture/identity-model.md`**. KERI concepts as implemented here: SAID computation, pre-rotation, inception/rotation/interaction events, the KEL structure. +5. **`docs/architecture/cryptography.md`**. The wire-format curve tagging rule (load-bearing). CESR encoding, multicodec encoding, the `CryptoProvider` abstraction. Read the "Wire-format Curve Tagging" section twice. +6. **`docs/architecture/multi_device_accepted_risks.md`**. The existing roadmap (Epics 1–6) and the accepted-risks doc. This is the canonical sequence of work to land the multi-device model correctly. +7. **`docs/plans/keri_compliance.md`**. The KERI compliance audit. Catalogs 30+ findings — several CRITICAL — that must be fixed before launch. Treat this as your work backlog. + +### Recommended reading (context) + +8. **`docs/architecture/attestation-format.md`**. JSON shape, canonicalization, dual signatures, capabilities, expiration. +9. **`docs/architecture/git-as-storage.md`**. How Git refs are used as the storage substrate. KEL layout, attestation layout, namespacing. +10. **`docs/security/primitive-inventory.md`**. Every cryptographic primitive in use, its backing library, its resolved version. Read before changing any crypto code. +11. **`docs/security/witness-diversity.md`**. The witness policy. Important for Epic 3. + +### Prior LLM analysis (mixed — use with discrimination) + +12. **`critique.md`**. A prior session's architectural and security review. Most observations stand. The threat-model commentary on `kt=1` + no witnesses is accurate. The crypto-leak findings (`sign_p256` missing from the trait, `rand::random()` in pairing, missing `cargo deny`) are correct and unfixed. +13. **`critique_epics.md`**. A prior session's epic plan. **The user has explicitly rejected its "fork KERI" recommendation.** Use it for the cross-cutting improvements that *don't* depend on forking — crypto-provider completion, `cargo deny`, dependency pinning, backup file format, multi-device escrow, agent delegation as headline. Ignore everything that proposes renaming `did:keri:` → `did:auths:`, replacing Blake3 with SHA-256, dropping CESR, dropping witnesses, or otherwise abandoning KERI compliance. + +--- + +## 4. Strategic posture for this session + +You are now operating under these explicit decisions. **Do not relitigate them unless the user opens the question.** + +1. **Stay with KERI.** Pursue full ToIP KERI v1.1 compliance. Interop with KERIpy / KERIox / Signify / KERIA is a goal, not a nice-to-have. The `did:keri:` identifier stays. +2. **CESR stays.** Indexed signatures, dual-index rotation signatures (Epic 1 in the existing roadmap), weighted thresholds — all per spec. +3. **Witnesses ship.** Verifier convergence requires them. Start with a single Auths-operated witness, design for the 3-witness diversity policy already documented. +4. **Multi-sig `kt ≥ 2`** is mandatory for shared identities. No `kt=1` escape hatch in production. +5. **P-256 default, Ed25519 supported.** Curve agility per the existing wire-format tagging rule. Do not narrow this without discussion. +6. **Pre-launch, no backwards compat.** Break wire formats freely as you fix them. +7. **Spec is the contract.** When the Rust impl disagrees with ToIP KERI v1.1, the spec wins. Fix the impl. + +--- + +## 5. Priority work + +The full sequence lives in `docs/architecture/multi_device_accepted_risks.md` (Epics 1–6) and is supplemented by `docs/plans/keri_compliance.md` (compliance audit findings). The aggregate priority order: + +### P0 — Spec-compliance wire-format fixes (Epic 4) + +These break interop with every other KERI implementation. Land them first, atomically, with cross-impl test vectors. Several are documented in `keri_compliance.md` with severity ratings: + +- **F-01** — `dt` field embedded in event body enters the SAID digest. Move out (CESR attachment group or external receipt). No other KERI impl has `dt` in-body. +- **F-06** — `serialize_for_signing` signs over body with `d`/`i` cleared but `v` still claiming populated size. Sign over the fully-finalized body bytes, matching KERIpy/KERIox. +- **F-14** — `auths-mobile-ffi` has private duplicates of `IcpEvent`, `compute_said`, `compute_next_commitment`, `finalize_icp_event` with an in-body `x` signature field. Externalize the signature via `serialize_attachment`; delete the duplicates; consume canonical types from `auths-keri`. +- **F-32** — P-256 verkey CESR code. `1AAI` is the non-transferable code; `1AAJ` is the *signature* code. Empirical audit against KERIox/KERIpy required. Likely needs coordinated CESR code assignment for P-256 transferable verkeys. +- **F-15** — Weighted threshold satisfaction. `simple_value().unwrap_or(1)` silently collapses weighted `nt` to threshold 1. Use typed `Threshold::is_satisfied` with verified commitment indices. +- **F-16** — `compute_next_commitment` hashes raw pubkey bytes; KERIpy hashes the CESR-qualified form. Empirical cross-impl test required. +- **F-10** — `Said` and `Prefix` derive `Default`; `new_unchecked` is `pub`. Trivially forgeable empty SAIDs. Seal both. +- **F-04, F-13** — Thresholds (`kt`, `nt`, `bt`) unvalidated at structural level. A malformed `kt=5, |k|=1` passes today. + +### P1 — Dual-index CESR signatures + true removal (Epic 1) + +Per `docs/architecture/multi_device_accepted_risks.md § Epic 1`. Adds `prior_index: Option` to `IndexedSignature`. Implements code-directed attachment parser. Enables shrink-`k` rotations and unblocks Epic 2. + +### P2 — Threshold upgrade `kt ≥ m` of `n` (Epic 2) + +Multi-sig signing protocol with partial-signature collection. Threshold-aware validators replacing every `simple_value().unwrap_or(...)`. Recovery semantics under `kt ≥ 2`. Migration of any existing `kt=1` KELs to upgraded thresholds. + +### P3 — Witness infrastructure (Epic 3) + +Wire receipt ingestion into the verifier path. KAWA threshold validation. Witness discovery (OOBI). Witness diversity policy enforcement per `docs/security/witness-diversity.md`. First-seen replay handling under realistic witness flows. + +### Cross-cutting (in parallel with P0–P3) + +- **`sign_p256` on `CryptoProvider` trait.** Six call sites construct `p256::ecdsa::SigningKey` directly today. Any FIPS swap is structurally inert until this lands. Documented in `docs/security/primitive-inventory.md § 6`. +- **`rand::random()` → `OsRng`** in `crates/auths-pairing-protocol/src/sas.rs:98`. Add the clippy deny rule with the fix. +- **`cargo deny` in CI.** No RUSTSEC, license, dup-version, or source check today. Add `deny.toml` and a CI gate. +- **Exact-pin crypto deps.** Caret ranges on `p256`, `chacha20poly1305`, `sha2`, `hkdf`, `ecdsa`, `signature`. Pin to `=x.y.z`. +- **`auths backup export / import`.** Single-device users today lose identity if `~/.auths` is lost. Pre-rotation does not help — same Keychain. Argon2id + AES-256-GCM (or ChaCha20-Poly1305) sealed bundle. +- **Disable Git GC on `~/.auths`** at init time. Lost objects = lost identity. +- **Cross-impl interop CI gate.** Round-trip auths-produced KELs through KERIox (Rust, tractable). Without this, you'll fix compliance findings and silently drift away again. +- **Decide Rekor trust-root.** `crates/auths-transparency/src/lib.rs:190-215` has `[0u8; 32]` placeholder. Either embed Sigstore's production Rekor public key or remove the integration until ready. +- **Rebuild `auths-mobile-ffi`** after F-14 lands. The current duplicate is a drift accelerator. + +### Deferred to post-launch + +- Mixed-curve controller sets (Epic 5) +- External federation (Epic 6) +- SCIM integration (`auths-scim`) +- Radicle integration (`auths-radicle`) +- Full multi-witness diversity (start with 1 witness at launch) + +--- + +## 6. Conventions you MUST follow + +These are project rules, not preferences. CI enforces several; the user enforces the rest by rejecting PRs that violate them. + +### Code conventions (from `CLAUDE.md`) + +- **Dependency direction is one-way.** Core/Id never imports SDK/API/CLI. Run `grep -r "use auths_api" crates/auths-sdk/src/` to spot violations. +- **`Utc::now()` is banned** in `auths-core/src/` and `auths-id/src/` outside `#[cfg(test)]`. Inject `ClockProvider`. +- **Collapsible `if`** — always use `&&` chains, never nested `if let`.

What NOT to do + +In order of how badly each would derail the project: + +1. **Do not propose forking the KERI wire format.** The user has rejected this direction. The work is to comply, not escape. +2. **Do not propose dropping witnesses.** They're how KERI achieves verifier convergence. Drop the witness *complexity* by starting with one witness; do not drop the *concept*. +3. **Do not weaken to `kt=1`** for shared identities anywhere in the production path. +4. **Do not bundle Rekor / Sigstore submission as a workspace crate.** Auths produces signed files; users submit them via `cosign` / `rekor-cli` / curl with standard tools. `auths-infra-rekor` should be deleted, not enhanced. +5. **Do not add `Utc::now()` to domain code.** Clippy will block it, but more importantly the discipline matters. +6. **Do not bypass the `CryptoProvider` trait.** Direct `p256::ecdsa::SigningKey::sign` is a bug; clippy will block it once the rule lands. +7. **Do not add `Default` to `Said` or `Prefix`.** F-10 is fixed by sealing, not preserved. +8. **Do not add backwards-compat shims.** None are owed. +9. **Do not introduce dependencies without checking `deny.toml`** (once it lands; until then, check the existing `Cargo.toml` patterns). +10. **Do not write commentary on code you didn't change.** A PR that "cleans up" unrelated files burns review attention. + +--- + +## 9. First-session checklist + +Before you propose your first concrete change, complete this checklist: + +- [ ] Read CLAUDE.md, SECURITY.md, ARCHITECTURE.md. +- [ ] Read `docs/architecture/identity-model.md` and `docs/architecture/cryptography.md`. +- [ ] Read `docs/architecture/multi_device_accepted_risks.md` end to end. +- [ ] Skim `docs/plans/keri_compliance.md` and identify which finding(s) the user's request touches. +- [ ] Run `git status` and `git log -10 --oneline` to see what work is in flight. +- [ ] Verify the user's request is consistent with the strategic posture in § 4. If they ask you to do something that contradicts those decisions (e.g., "let's fork KERI after all"), confirm before doing. +- [ ] Identify the specific files that will change. State them before editing. +- [ ] Plan the minimum coherent diff. No drive-by cleanups, no unrelated refactors. + +When in doubt: read more code before suggesting changes. The codebase is dense and well-structured; skimming produces confidently wrong advice. The user values precise, narrow, correct changes over broad, vague, plausible-sounding ones. + +--- + +## 10.

If Y is on a planned-swap row (FIPS/CNSA), defer to the planned swap.
