From e0971cc72c1535eb92a3f2c0737a3792c07f8022 Mon Sep 17 00:00:00 2001 From: "Claude Opus 4.8" Date: Sat, 6 Jun 2026 08:05:36 +0000 Subject: [PATCH 01/58] =?UTF-8?q?P0.1=20=E2=80=94=20app=20skeleton=20&=20s?= =?UTF-8?q?eeded=20config?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Foundation for Vector (Next.js App Router + TS strict, Bun toolchain): - Single source of truth: lib/config/constants.ts — every scoring/routing/ timing/signal/policy/capital/chain constant, zod-validated at load and deeply frozen (mutation throws; invalid values crash startup). - Server-only env: zod schema + pure parser (env.schema.ts) with redacted, value-free error messages; eager server-only entry (env.ts). Secrets never reach the client bundle. - Neon client: server-only pool singleton; checkDb() is a total function that collapses every failure (refused/TLS/disconnect/timeout) to 'down'. - /api/health: real SELECT 1, returns { ok, db, config_loaded, commit } (200 up / 503 down). Pure formatter in lib/health.ts. - SWR provider polling at the single ui_poll_ms cadence (no sockets). - Tests (~10% happy / ~90% edge): unit, fuzz (seeded), integration (gated on DATABASE_URL), e2e single-source invariant. 54 pass. - Docs: config.md, env.md, ADR 0001; .env.example; README. Verified: tsc --noEmit, eslint, prettier --check, bun test, next build — all clean. --- .env.example | 21 + gitignore => .gitignore | 3 +- .prettierignore | 5 + .prettierrc.json | 7 + README.md | 49 ++ app/api/health/route.ts | 18 + app/health/page.tsx | 30 + app/layout.tsx | 20 + app/page.tsx | 28 + app/providers.tsx | 39 + bun.lock | 786 ++++++++++++++++++ .../adr/0001-seeded-config-and-swr-polling.md | 58 ++ docs/config.md | 109 +++ docs/env.md | 36 + eslint.config.mjs | 18 + lib/config/constants.schema.ts | 167 ++++ lib/config/constants.ts | 101 +++ lib/config/derive.ts | 22 + lib/config/env.schema.ts | 110 +++ lib/config/env.ts | 15 + lib/db/client.ts | 55 ++ lib/health.ts | 41 + lib/utils/deep-freeze.ts | 26 + next.config.mjs | 20 + package.json | 44 + tests/e2e/single-source.e2e.test.ts | 88 ++ tests/fuzz/config.fuzz.test.ts | 63 ++ tests/fuzz/env.fuzz.test.ts | 74 ++ tests/integration/db.integration.test.ts | 51 ++ tests/unit/config.test.ts | 107 +++ tests/unit/env.test.ts | 106 +++ tests/unit/health.route.test.ts | 64 ++ tests/unit/health.test.ts | 43 + tsconfig.json | 30 + 34 files changed, 2452 insertions(+), 2 deletions(-) create mode 100644 .env.example rename gitignore => .gitignore (97%) create mode 100644 .prettierignore create mode 100644 .prettierrc.json create mode 100644 README.md create mode 100644 app/api/health/route.ts create mode 100644 app/health/page.tsx create mode 100644 app/layout.tsx create mode 100644 app/page.tsx create mode 100644 app/providers.tsx create mode 100644 bun.lock create mode 100644 docs/adr/0001-seeded-config-and-swr-polling.md create mode 100644 docs/config.md create mode 100644 docs/env.md create mode 100644 eslint.config.mjs create mode 100644 lib/config/constants.schema.ts create mode 100644 lib/config/constants.ts create mode 100644 lib/config/derive.ts create mode 100644 lib/config/env.schema.ts create mode 100644 lib/config/env.ts create mode 100644 lib/db/client.ts create mode 100644 lib/health.ts create mode 100644 lib/utils/deep-freeze.ts create mode 100644 next.config.mjs create mode 100644 package.json create mode 100644 tests/e2e/single-source.e2e.test.ts create mode 100644 tests/fuzz/config.fuzz.test.ts create mode 100644 tests/fuzz/env.fuzz.test.ts create mode 100644 tests/integration/db.integration.test.ts create mode 100644 tests/unit/config.test.ts create mode 100644 tests/unit/env.test.ts create mode 100644 tests/unit/health.route.test.ts create mode 100644 tests/unit/health.test.ts create mode 100644 tsconfig.json diff --git a/.env.example b/.env.example new file mode 100644 index 0000000..1d949ce --- /dev/null +++ b/.env.example @@ -0,0 +1,21 @@ +# Vector — environment variables (P0.1) +# Copy to `.env.local` and fill in real values.

charset=UTF-8 Content-Transfer-Encoding: 8bit What - Full §7.1 schema as SQL DDL (lib/db/migrations/0001_*): agents, rounds, intents, policy_events, executions, outcomes, scores, capital_allocations, attestations, kill_switch — uuid PKs, timestamptz, numeric-only money/scores. - Enum domains named separately (agents.status vs executions.status; etc.). intents.action {open,close,modify,transfer}; capital_allocations.trigger widened to {settle,attestation,crash,operator} per §6.2. - Invariants in SQL: kill_switch singleton (id=1 + CHECK); attestations unique (agent_id, round_id); intents.target_address only on transfer; outcomes. execution_id nullable (seeded arc); value bounded to int128, value_decimals to uint8; feedback_hash/tx_hash hex-format checks; weights/CaR/fees ranges. All FKs ON DELETE RESTRICT (no dangling rows). Read-path indexes for P1.5. - Migration runner (lib/db/migrate.ts): paired up/down SQL, schema_migrations ledger, per-migration transaction (atomic), pg_advisory_lock (serializes concurrent runners), idempotent. No ORM (see ADR 0002). - Typed repository layer (lib/db/repos/*): parameterized insert/select per table over an injected Queryable; zod row validation; numeric as string to preserve precision. Parameter binding only — no SQL string concatenation. - Smoke seed (one idempotent row per table) + data reset; CLI scripts db:migrate / db:rollback / db:seed / db:reset. - docs/data-model.md (tables, enum domains, truth map §7.2, mermaid ER, migration runbook) + ADR 0002 (tooling rationale). Tests - unit: SQL builder + identifier guard (injection), migration plan/apply (BEGIN/COMMIT/ROLLBACK), repo mapping/param-binding/enum/zod-reject. - fuzz: assertIdent accepts iff safe pattern; buildInsert never inlines values. - integration (real Neon, throwaway schema): every table+index present, happy FK joins + leaderboard, singleton, unique attestation, FK violation, bad enum, NOT NULL, target-only-on-transfer, numeric/int128/uint8/negative guards, RESTRICT on delete-with-children, reset + re-seed, repo round-trip. - e2e (real Neon): idempotent re-apply, full down→up integrity, atomic rollback on mid-migration failure, two concurrent migrators serialize. Verification - tsc --noEmit, eslint, prettier: clean. - next build: ok (DATABASE_URL set, unchanged P0.1 behavior). - 105 tests pass / 0 fail across unit+fuzz+integration+e2e. - `test` script now runs suites as separate processes: bun's mock.module is process-global, so mock-based unit tests must not share a process with the real-DB suites. --- docs/adr/0002-migration-tooling-and-no-orm.md | 43 ++++ docs/data-model.md | 207 +++++++++++++++ lib/db/migrate.ts | 200 +++++++++++++++ lib/db/migrations/0001_data_model.down.sql | 29 +++ lib/db/migrations/0001_data_model.up.sql | 211 ++++++++++++++++ lib/db/repos/_shared.ts | 57 +++++ lib/db/repos/agents.ts | 43 ++++ lib/db/repos/attestations.ts | 58 +++++ lib/db/repos/capital-allocations.ts | 46 ++++ lib/db/repos/executions.ts | 38 +++ lib/db/repos/index.ts | 15 ++ lib/db/repos/intents.ts | 70 ++++++ lib/db/repos/kill-switch.ts | 32 +++ lib/db/repos/outcomes.ts | 54 ++++ lib/db/repos/policy-events.ts | 46 ++++ lib/db/repos/rounds.ts | 27 ++ lib/db/repos/scores.ts | 37 +++ lib/db/schema.ts | 184 ++++++++++++++ lib/db/seed.ts | 115 +++++++++ lib/db/sql.ts | 50 ++++ lib/db/types.ts | 14 ++ package.json | 8 +- scripts/db/_pool.ts | 15 ++ scripts/db/migrate.ts | 25 ++ scripts/db/reset.ts | 26 ++ scripts/db/rollback.ts | 44 ++++ scripts/db/seed.ts | 21 ++ tests/e2e/data-model.e2e.test.ts | 145 +++++++++++ tests/fuzz/sql.fuzz.test.ts | 70 ++++++ .../data-model.integration.test.ts | 238 ++++++++++++++++++ tests/unit/migrate.test.ts | 108 ++++++++ tests/unit/repos.test.ts | 204 +++++++++++++++ tests/unit/sql.test.ts | 62 +++++ 33 files changed, 2540 insertions(+), 2 deletions(-) create mode 100644 docs/adr/0002-migration-tooling-and-no-orm.md create mode 100644 docs/data-model.md create mode 100644 lib/db/migrate.ts create mode 100644 lib/db/migrations/0001_data_model.down.sql create mode 100644 lib/db/migrations/0001_data_model.up.sql create mode 100644 lib/db/repos/_shared.ts create mode 100644 lib/db/repos/agents.ts create mode 100644 lib/db/repos/attestations.ts create mode 100644 lib/db/repos/capital-allocations.ts create mode 100644 lib/db/repos/executions.ts create mode 100644 lib/db/repos/index.ts create mode 100644 lib/db/repos/intents.ts create mode 100644 lib/db/repos/kill-switch.ts create mode 100644 lib/db/repos/outcomes.ts create mode 100644 lib/db/repos/policy-events.ts create mode 100644 lib/db/repos/rounds.ts create mode 100644 lib/db/repos/scores.ts create mode 100644 lib/db/schema.ts create mode 100644 lib/db/seed.ts create mode 100644 lib/db/sql.ts create mode 100644 lib/db/types.ts create mode 100644 scripts/db/_pool.ts create mode 100644 scripts/db/migrate.ts create mode 100644 scripts/db/reset.ts create mode 100644 scripts/db/rollback.ts create mode 100644 scripts/db/seed.ts create mode 100644 tests/e2e/data-model.e2e.test.ts create mode 100644 tests/fuzz/sql.fuzz.test.ts create mode 100644 tests/integration/data-model.integration.test.ts create mode 100644 tests/unit/migrate.test.ts create mode 100644 tests/unit/repos.test.ts create mode 100644 tests/unit/sql.test.ts diff --git a/docs/adr/0002-migration-tooling-and-no-orm.md b/docs/adr/0002-migration-tooling-and-no-orm.md new file mode 100644 index 0000000..74f06f5 --- /dev/null +++ b/docs/adr/0002-migration-tooling-and-no-orm.md @@ -0,0 +1,43 @@ +# ADR 0002 — Migration tooling: a thin SQL runner, no ORM + +- Status: accepted (P0.2) +- Context: §7 needs the full Neon schema with forward + rollback migrations, a + typed repository layer, and idempotent seed/reset. + +## Decision + +Use a **minimal SQL-file migration runner built on the Neon client the repo +already uses**, and a **hand-written typed repository layer** — no ORM and no +external migration framework. + +- Migrations are paired `NNNN_name.up.sql` / `.down.sql` files applied by + `lib/db/migrate.ts`, which keeps a `schema_migrations` ledger, runs each + migration in its own transaction, and takes a `pg_advisory_lock` so concurrent + runners serialize. +- Repositories (`lib/db/repos/*`) build parameterized statements and validate + rows with the zod schemas already in the stack. + +## Why (reuse-check) + +We considered `drizzle-kit` and `node-pg-migrate` first, per the brief. + +- **drizzle / any ORM** contradicts the brief's explicit "no superfluous ORM + abstractions" for the repo layer, and would add a second schema source of + truth alongside the SQL DDL. +- **node-pg-migrate** is built around the `pg` TCP client; the repo standardized + on `@neondatabase/serverless` in P0.1 (ADR 0001).

charset=UTF-8 Content-Transfer-Encoding: 8bit Implement Vector's single trust boundary: a typed, signed Intent and an ordered validation pipeline that is independent of agents and the referee. Only a structurally valid, authentic Intent crosses B1, so a prompt-injected agent cannot bypass the gate — free-form model output is never executed. What - lib/intent/schema.ts: zod discriminated union on `action` (open/modify/close/transfer), .strict(); JSON Schema export; Intent/ UnsignedIntent types derived via z.infer/z.input (single source of truth, no drift under exactOptionalPropertyTypes). - lib/intent/canonical.ts: numeric-as-string normalization (1 == 1.0 == "1"), ISO-8601 ttl + nonce normalization, deterministic key-sorted serialization, intent_hash = keccak256(canonical payload). Precision cap rejects absurd literals without panic. - lib/intent/sign.ts + verify.ts: EIP-191 personal_sign over the canonical payload via viem; recovery/verification never throw on malformed input — a failed auth is a deterministic reject. ERC-1271 left as the single seam in verify.ts (out of scope for EOA seed agents). - lib/intent/validate.ts: first-failing ordered checks schema → signature → nonce → ttl → bounds → target_address, returning a typed {ok,stage,code}. Nonce single-admission via an atomic reserve guard; ttl skew/horizon opt-in. Policy (whitelist, caps, drain detection) is the referee's job (P1.1), not this boundary. - docs/intent-contract.md + docs/examples/signed-intent.json: normative spec and a pinned, byte-stable conformance vector. Reuse-first: crypto via viem (keccak256/EIP-191), JSON Schema via zod-to-json-schema — no hand-rolled primitives. Tests - Happy ~10% / edge ~90%; unit + seeded fuzz (deterministic PRNG) + e2e + integration (full path → real Neon `intents`, isolated schema). - Golden/regression vectors pin payload, hash, and signature. - lib/intent coverage: 100% functions / 100% lines. Verification - tsc, eslint, prettier clean; `bun run test` (unit+fuzz+integration+e2e) green incl. DATABASE_URL; `next build` green. --- bun.lock | 30 +++ docs/examples/signed-intent.json | 18 ++ docs/intent-contract.md | 170 +++++++++++++++++ lib/intent/canonical.ts | 130 +++++++++++++

Implements architecture.txt §8. + +An autonomous agent in Vector earns the right to move capital, but it never holds +the keys to do so. The **Intent** is the only thing that crosses from the agent's +world (untrusted reasoning, possibly prompt-injected) into Vector's world +(execution against real markets). This document is the normative reference for +that contract: its shape, how it is canonicalized, how it is signed, and the +exact order in which the referee validates it. + +If it isn't a typed, signed Intent, it does not cross the boundary. That single +rule is why prompt injection cannot drain the system (boundary **B1**, §5.3): +free-form model output is never executed — only a structurally valid, authentic +Intent is. + +--- + +## 1. Where P0.3 sits + +``` + agent.decide(context) ──▶ UnsignedIntent ──▶ harness signs ──▶ Intent ──▶ validateIntent ──▶ referee policy + (untrusted) (proposal) (lib/intent/sign) (signed) (lib/intent/validate) (P1.1) + └────────── P0.3 ends here ──────────┘ +``` + +P0.3 owns **authenticity and well-formedness**. It answers: *is this a +syntactically valid Intent, genuinely signed by the agent it claims, fresh, and +within absolute sanity bounds?* It deliberately does **not** answer *should we +allow it?* — market whitelisting, per-agent trade caps, fresh-wallet/drain +detection, and budget enforcement are **referee policy (P1.1)**, layered on top. + +## 2. Intent shape (§8.2) + +An Intent is a discriminated union on `action`. All fields are strings on the +wire (see §4 on numerics). The schema is `lib/intent/schema.ts`; the JSON Schema +is exported via `intentJsonSchema` / `unsignedIntentJsonSchema` for external +conformance. + +| field | open | modify | close | transfer | notes | +| ---------------- | :--: | :----: | :---: | :------: | ---------------------------------------- | +| `action` | ✓ | ✓ | ✓ | ✓ | the discriminant | +| `agent_id` | ✓ | ✓ | ✓ | ✓ | the claimed issuer | +| `nonce` | ✓ | ✓ | ✓ | ✓ | unique per `(agent_id, nonce)` | +| `ttl` | ✓ | ✓ | ✓ | ✓ | ISO-8601 UTC expiry | +| `size` | ✓ | ✓ | ✓ | ✓ | canonical decimal string | +| `market` | ✓ | ✓ | ✓ | | symbol, e.g. `BTC-PERP` | +| `side` | ✓ | ✓ | | | `long` \| `short` | +| `leverage` | ✓ | ✓ | | | canonical decimal string | +| `max_slippage` | ✓ | ✓ | ✓ | | fraction in `[0, 1]` | +| `tp` / `sl` | ? | ? | | | optional take-profit / stop-loss | +| `target_address` | | | | ? | **only** valid on `transfer` | +| `signature` | ✓ | ✓ | ✓ | ✓ | EIP-191 sig over the canonical payload | + +The schema is `.strict()`: unknown keys are rejected. Types are derived from the +schema with `z.infer` / `z.input` (single source of truth) so the runtime +contract and the TypeScript types can never drift. + +### Conditional obligation + +`target_address` is the load-bearing conditional: it is **structurally permitted +on every action** by the schema but **only legal on `transfer`**, enforced as the +last validation step (§6f) and backstopped by a DB `CHECK` (P0.2). This is +intentional: keeping it a distinct, observable validation step (rather than a +schema rejection) makes the failure reason explicit and auditable, and prevents a +malformed-but-injected `target_address` from being silently dropped. + +## 3. Canonicalization (`lib/intent/canonical.ts`) + +A signature is only meaningful if both signer and verifier agree, byte-for-byte, +on *what was signed*. The canonical payload is the deterministic serialization of +all **present** Intent fields **except `signature`**: + +- keys sorted lexicographically at every depth (`stableStringify`); +- absent optional fields are **omitted**, never serialized as `null`; +- all numerics normalized to a single canonical decimal string (§4); +- `ttl` normalized to ISO-8601 UTC (`...000Z`); +- `nonce` normalized to its string token. + +`intent_hash = keccak256(utf8(canonical_payload))`, a `0x`-prefixed 32-byte hex +string. The hash is stored in the `intents` table and is the stable external +identifier of an Intent. + +## 4. Numerics: string end-to-end + +Floating point cannot represent prices and sizes exactly, so the contract is +**numeric-as-string end-to-end**. On input a field may be a JS `number` *or* a +string; it is immediately normalized to a canonical decimal string: + +``` +1 → "1" 1.0 → "1" "1.500" → "1.5" +.5 → "0.5" "1e3" → "1000" "-0.0" → "0" +``` + +Consequence: `size: 1`, `size: 1.0`, and `size: "1.000"` produce an **identical +canonical payload, hash, and signature**. `NaN`, `Infinity`, and non-decimal +strings are rejected at the schema layer. There is a precision cap on literal +length to bound work and reject absurd inputs without panicking. + +## 5. Signing convention (`sign.ts` / `verify.ts`) + +Signing uses **EIP-191 `personal_sign`** (`viem`'s `signMessage`) over the UTF-8 +canonical payload: + +```ts +const intent = await signIntent(unsignedInput, privateKey); // adds `signature` +const signer = await recoverIntentSigner(intent); // EIP-191 recovery +const ok = await verifyIntentSignature(intent, expected); // checksum-insensitive +``` + +- The agent holds no key and cannot sign; the harness signs on behalf of the + agent's registered address. The agent can only *propose* an `UnsignedIntent`. +- Recovery/verification never throws on a malformed signature or address — they + return `false` (a failed auth is a deterministic *reject*, not an exception). +- **ERC-1271 (smart-contract signers)** is intentionally **out of scope for + P0.3**: seed agents use EOAs. When contract-account agents are introduced, + `verifyIntentSignature` is the single seam to extend (EOA `ecrecover` → + `isValidSignature` fallback); nothing else in the pipeline changes. + +## 6. Validation order (§8, normative) + +`validateIntent(input, opts)` runs these checks **in order and stops at the first +failure**, returning `{ ok: false, stage, code, message }`. Order matters: a +cheaper/more fundamental failure must mask a later one so the reported reason is +stable and an attacker can't probe later checks by satisfying earlier ones. + +| # | stage | rejects when… | example code | +| - | ---------------- | ---------------------------------------------------- | ------------------------- | +| a | `schema` | shape/type invalid, unknown key, bad numeric | `invalid_schema` | +| b | `signature` | signer unauthorized, or signature ≠ canonical payload | `unknown_signer`, `bad_signature` | +| c | `nonce` | `(agent_id, nonce)` already seen (replay) | `replayed_nonce` | +| d | `ttl` | expired (with optional clock-skew / max-horizon) | `expired`, `ttl_too_far` | +| e | `bounds` | size/leverage ≤ 0, slippage ∉ [0,1], tp/sl ≤ 0 | `nonpositive_size`, … | +| f | `target_address` | present on a non-`transfer` action | `target_only_on_transfer` | + +On success it returns `{ ok: true, intent, intent_hash }`. + +Notes on the seams the caller wires in: + +- **Nonce (c)** is checked via an injected `isNonceUsed(agentId, nonce)`. The + validator is *pure*; it cannot by itself prevent a concurrent double-spend. + Single-admission under a replay storm is enforced by an **atomic reserve** — + `createNonceGuard()` in-process, or a unique constraint / `INSERT … ON + CONFLICT` on `(agent_id, nonce)` in the DB. `reserve` wins exactly once. +- **TTL (d)** defaults to *no* future horizon and *no* skew; both are opt-in + (`maxTtlHorizonMs`, `clockSkewMs`). `now === ttl` is still valid (expiry is + exclusive of the boundary by `<` comparison after skew). +- **Signer authority (b)** is resolved by an injected `resolveSigner(agentId)` + returning the agent's authorized address (or `null` → `unknown_signer`). + +## 7. What P0.3 is **not** + +These belong to the referee (P1.1) and later phases, *not* this boundary: + +- market whitelist, per-trade and per-round size caps, leverage caps; +- fresh-wallet / drain heuristics on `transfer` targets (a signed transfer to any + address is structurally valid here — see the e2e tests); +- budget/allocation enforcement; +- ordering/fairness across agents within a round. + +A signed `transfer` to `0x…dead` **passes** P0.3. That is correct: P0.3 proves it +is well-formed and authentic; the referee decides it is not *allowed*. + +## 8. Reference example + +See [`docs/examples/signed-intent.json`](./examples/signed-intent.json) — a +pinned, byte-stable signed Intent (signer = Anvil account #0) with its canonical +payload and `intent_hash`. It is asserted by `tests/unit/intent.golden.test.ts`, +so any change to canonicalization, hashing, or the signing convention fails CI +loudly.

charset=UTF-8 Content-Transfer-Encoding: 8bit Security audit of the P0.3 boundary found one real, exploitable issue in normalizeDecimal: the MAX_DECIMAL_DIGITS cap counted only significant digits, not the positional expansion from a scientific-notation exponent. A tiny literal such as `size: "1e999999999"` therefore slipped past the cap and was materialized into a multi-gigabyte string via `'0'.repeat(...)`, hanging or OOM-ing the process. This fires at the schema stage (a) of validateIntent — on attacker-controlled numeric fields (size/leverage/max_slippage/tp/sl) and *before* any signature verification — so it is an unauthenticated amplification DoS (~12 input bytes → gigabytes). Reproduced: "1e8000000" expanded to an 8 MB string; larger exponents hung the process. Root cause / fix: bound the full positional span (leading integer + trailing fractional places) by the same MAX_DECIMAL_DIGITS cap and reject in O(1) before any allocation. This is the minimal extension of the existing precision guard — no new dependency, consistent with the module's canonical-string approach. The cap sits at the same boundary as the digit cap (1e79 is the largest accepted power of ten; 1e80 is rejected); all legitimate financial magnitudes pass unchanged. Tests - unit: exponent bombs (±) throw `/maximum precision/` in <100ms each; 1e79 passes, 1e80 rejected (boundary). - e2e: an exponent bomb routed through validateIntent fails at stage `schema` in O(1) (no allocation), proving the gate cannot be hung pre-auth. Verification: tsc / eslint / prettier clean; full `bun run test` (unit+fuzz+integration+e2e, with DATABASE_URL) green; `next build` green; lib/intent coverage remains 100% functions / 100% lines. Audit notes (reviewed, no change needed): - signature binds agent_id + nonce (mutation breaks recovery); cross-agent replay is rejected at the signature stage. - ECDSA s-malleability is not exploitable: dedup keys on intent_hash / (agent_id,nonce), neither of which includes the signature. - nonce TOCTOU between read and durable reserve remains the caller's responsibility (DB unique index / createNonceGuard.reserve), as documented. --- lib/intent/canonical.ts | 12 ++++++++++++ tests/e2e/intent.e2e.test.ts | 23 +++++++++++++++++++++++ tests/unit/intent.canonical.test.ts | 14 ++++++++++++++ 3 files changed, 49 insertions(+) diff --git a/lib/intent/canonical.ts b/lib/intent/canonical.ts index 00107cc..f634f73 100644 --- a/lib/intent/canonical.ts +++ b/lib/intent/canonical.ts @@ -54,6 +54,18 @@ export function normalizeDecimal(input: number | string): string { // Position of the decimal point within `digits`, shifted by any exponent. const pointPos = intDigits.length + (m[4] ? parseInt(m[4], 10) : 0); + // Guard against exponent-driven expansion: a tiny literal like "1e8000000" + // has few significant digits (so it slips past the digit cap above) yet would + // expand to millions of positional zeros below, allocating gigabytes from a + // handful of input bytes.

No change to the accepted happy-path wire shape; golden vectors unchanged. What - canonical.ts `normalizeTimestamp`: reject lenient/ambiguous date strings. String input must now be a strict ISO-8601 instant with an explicit timezone (`Z` or `±HH:MM`/`±HHMM`); `number` is epoch-ms. Previously any string went to `new Date(...)`, so a timezone-less datetime was parsed in the *host's local zone* — making the canonical payload host-dependent (signature verification fails across hosts with different TZ, and ttl meaning shifts ±offset), and garbage like "2031" / "Jan 1 2030" / "01/02/2030" was silently accepted as a valid expiry. Determinism is the whole point of the canonical payload. - validate.ts `inUnitInterval`: compare on the canonical decimal string instead of `Number(d)`. A float comparison rounds e.g. "1.0000000000000001" down to 1 and admits a max_slippage strictly > 1; the gate must honour the exact bytes it signed/hashed (numerics are canonical strings end-to-end). - canonical.ts `normalizeNonce`: reject numeric nonces beyond Number.MAX_SAFE_INTEGER. Past 2^53 a JSON number has already lost precision, so two distinct nonces (2^53 vs 2^53+1) alias to one canonical token in the anti-replay key and wrongly reject a legitimate Intent as a replay. Use a string nonce for large/opaque values. Why these only - Domain separation (cross-instance/chain signed-Intent replay) and the published JSON-Schema↔parser fidelity gap are real but change the signed wire format / are architecture decisions — escalated separately, not auto-fixed. - maxTtlHorizon/isNonceUsed fail-open defaults are by-design opt-in (referee / durable store own them); left as-is. Tests - canonical: normalizeTimestamp rejects tz-less, bare year, locale dates, digit-string, out-of-range fields; accepts Z and numeric offset. normalizeNonce rejects unsafe-integer numbers, keeps string nonces of the same magnitude. - validate: max_slippage "1.0000000000000001" rejected; 0 / 1 / "0.5" accepted.

The SQL-injection posture (parameterized binds + assertIdent) and the SQL↔zod schema mapping were already sound and are unchanged. What - repos/_shared.ts `num()`: reject a JS `number` that is not an exactly representable safe integer. A non-integer (`0.1 + 0.2` → "0.30000000000000004") or an integer past 2^53 (an int128 `attestations.value` or a bigint block number passed as a number) has already lost precision before `num()` runs; coercing it via `.toString()` silently persisted a corrupted money/score/on-chain value into a `numeric` column, violating the project's "numeric is exact, never through a float" invariant. Safe integers (e.g. `score_r: 50`) and exact strings/bigints still pass; bad inputs now throw so the caller supplies an exact string. - migrate.ts `assertSessionConnection` (new, run at the start of `migrate()`): fail closed when the connection does not preserve session state across statements — i.e. a transaction-pooled endpoint (Neon `-pooler` / PgBouncer transaction mode). The runner relies on two session-scoped guarantees, the `pg_advisory_lock` migration mutex and `SET search_path`; on a pooled endpoint both silently no-op, so migrations would not be serialized and DDL could land in `public` instead of the target schema. Detected generically by setting a session GUC and reading it back on a separate statement. - migrate.ts `loadMigrations`: throw on a duplicate version+direction instead of letting readdir order silently pick a winner — completes the documented "a malformed set throws before any SQL runs" invariant (only missing-half was caught before). - migrate.ts error handling: a failing ROLLBACK no longer masks the original migration error (the real root cause), and a failing advisory-unlock in `finally` no longer turns an already-committed migration into a thrown error. - seed.ts `resetData`: refuse the destructive TRUNCATE-all when current_schema is `public`. The helper is exported from `lib/` with no guard; this blocks a `public`/production-bound connection being passed in by mistake. Legitimate callers run inside a dedicated non-public schema via search_path. Why these only - Schema CHECK gaps flagged by the audit (tp/sl ≥ 0, delta ∈ [-1,1]) are intentionally omitted per the data-model spec (referee owns intent validation) — left as-is. assertIdent reserved-word quoting / 63-byte bound and the health-probe in-flight-connection retention are defense-in-depth with no current exploit; not changed here. Tests - num: rejects non-integer / >2^53 / NaN / Infinity; accepts safe int, string, bigint (incl. int128-scale). - loadMigrations: throws on a duplicate up for a version. - applyMigration: a failing ROLLBACK still surfaces the original error. - assertSessionConnection: resolves on a persistent session, throws when state is dropped between statements. - resetData: refuses on `public`, truncates inside a non-public schema.

The wall-clock Promise.race is kept only as a backstop on the HTTP response time. Why - The probe's timeout was a *racing promise*, not cancellation. When the timer won, checkDb returned 'down' but the losing `getPool().query('SELECT 1')` kept running on its acquired connection with no driver-level bound (the Pool has no connectionTimeoutMillis / statement_timeout). Under a slow or hung backend each in-flight probe pinned one of the pool's connections for as long as the underlying op took — far beyond the 2s the caller was promised. /api/health is unauthenticated and force-dynamic, so a burst during a DB blip (or a flood) could pin every connection in the shared process-wide pool and amplify a transient slowdown into a full outage. The advertised "bounded by 2s" was illusory for resource holding. - Now statement_timeout cancels the query server-side and the `finally` releases the client promptly, so 'down' is reported AND the connection is freed. The result stays a total function (every failure → 'down', never throws). Scope - Only the health probe is touched. The shared getPool() config is left as-is to avoid changing connect semantics for the repo/migration pools; bounding a hung *connect* (vs query) via Pool connectionTimeoutMillis is noted as an optional follow-up. Other audit findings (missing baseline HTTP security headers; the health page rendering the fetcher error instead of the db:down payload; deepFreeze robustness on frozen/cyclic graphs; explorerTxUrl URL-encoding) are defense-in-depth / non-security / latent-until-later-stage and were filtered, not fixed. Tests - Updated tests/unit/health.route.test.ts: the Neon fake now models the connect → client.query → release shape the probe uses (behavioral assertions — 200/up, 503/down on reject, down on slow — unchanged). Verification - tsc --noEmit, eslint, prettier --check: clean. - bun test per suite (the project's test command runs them as separate processes): unit 63, fuzz 18, integration 17 (real Neon, incl. checkDb up/concurrent/timeout), e2e 8 — all green. - next build: ok. --- lib/db/client.ts | 33 ++++++++++++++++++++++++--------- tests/unit/health.route.test.ts | 9 +++++++-- 2 files changed, 31 insertions(+), 11 deletions(-) diff --git a/lib/db/client.ts b/lib/db/client.ts index 8fbef75..522b954 100644 --- a/lib/db/client.ts +++ b/lib/db/client.ts @@ -32,21 +32,36 @@ const DEFAULT_PROBE_TIMEOUT_MS = 2_000; * timeout — collapses to `'down'`.

When the suite runs with DATABASE_URL set, the gated db.integration test primes that singleton with the real driver and then calls getPool().end() without clearing the cached reference. The next file, health.route.test, relies on mock.module('@neondatabase/serverless') to keep checkDb hermetic, but getPool() hands back the stale (ended/real) pool instead of one built from the mock, so the probe fails and the route returns 503 -> the "returns 200" test fails. It passed in isolation and pairwise, which masked the cross-file leak; it reproduces deterministically on main once DATABASE_URL is set. Fix at the root: add a test-only resetPool() that drops the cached singleton, and call it in the health test's beforeAll (so checkDb rebuilds a pool from the mocked driver) and afterAll (so this file's mock pool never leaks to later files). No production path uses resetPool; connection lifecycle stays the creator's job.

Fix: evaluate in two phases. - BLOCKING_RULES (HALT/REJECT) run first; first fire decides. drawdown_breaker and the zero-budget spend reject move ahead of the soft caps so a terminal decision can never be skipped. - CLIPPING_RULES run only if nothing blocked and now *accumulate*: every breached cap is clamped in one CLIP (size -> min(max_trade_size, remaining), leverage -> max_leverage), so clipping one field can't let another through. - spend_cap split into spendCapRejectRule (blocking) + spendCapClipRule (clipping); both still report rule_fired='spend_cap'. A lone clip is reported verbatim; multiple join rule ids with '+' and record each in detail.clips[]. Also: runReferee now fails closed — an unexpected error during validate/evaluate records a terminal internal_error REJECT policy_event (err.name only, no message) before re-throwing, preserving the one-event-per-decision audit invariant. Tests: rewrote the ordering tests that encoded the bug; added regressions (drawdown HALT and zero-budget REJECT beat an over-size clip; size+leverage both clamped; size clamped to the smaller of cap/budget). Strengthened the fuzz invariant so ANY clip result satisfies ALL caps, not just the rule that fired. docs/referee.md: two-phase decision matrix + caller-contract / non-guarantees. --- docs/referee.md | 91 ++++++++++++++++++++++------- lib/referee/evaluate.ts | 60 ++++++++++++++++--- lib/referee/index.ts | 2 +- lib/referee/record.ts | 46 +++++++++++---- lib/referee/rules/index.ts | 48 +++++++++------ lib/referee/rules/spend-cap.ts | 69 +++++++++++++--------- tests/fuzz/referee.fuzz.test.ts | 23 ++++++-- tests/unit/referee.evaluate.test.ts | 56 ++++++++++++++---- tests/unit/referee.rules.test.ts | 39 ++++++++++--- 9 files changed, 321 insertions(+), 113 deletions(-) diff --git a/docs/referee.md b/docs/referee.md index 8bb44ad..d65bbc2 100644 --- a/docs/referee.md +++ b/docs/referee.md @@ -10,24 +10,41 @@ decision. inputs always yield the same decision and the same `policy_event`.

charset=UTF-8 Content-Transfer-Encoding: 8bit Pre-P1.2 hardening of audit findings, on a dedicated branch. #1 nonce-replay (durable): migration 0002 adds UNIQUE(agent_id, nonce) on intents so a replayed Intent insert fails atomically in the DB, independent of process-local state (P0.3 had only an in-memory guard). New repo primitives insertIntentReserving (INSERT ... ON CONFLICT DO NOTHING; null = replay) and isNonceUsed (durable read); buildInsert gains an onConflictDoNothing option and insertOneOrNull backs it. NULL nonces stay exempt (NULLs distinct). #3 statement_timeout leak: checkDb now scopes the probe timeout to a transaction (set_config(..., is_local=true) inside BEGIN/COMMIT) so it is discarded on commit and never leaks onto the pooled connection. #4 pool error handler: getPool attaches an idle-client error listener so a Neon idle-connection drop no longer crashes the process; logs only err.name. #5b numeric scale guard: the validator rejects a numeric field with finer fractional scale than its numeric(p,s) column can store (silent-rounding / integrity guard). Magnitude is intentionally NOT bounded here — the firewall clips over-large size/leverage (§6.5). schema: .max() length bounds on agent_id/market/target_address (pre-signature DoS guard). Tests: +ON CONFLICT/insertOneOrNull, +scale-guard & magnitude-pass cases, +schema length bounds, +checkDb transaction-shape and pool-error-swallow regressions, +intents anti-replay integration on live Neon.

Mixing a `[0,1]` term +(`perf·w`) with point-scale penalties inside a `[0,1]` clamp is only coherent if +the penalties are read as points, i.e. + +``` +raw_r = clamp(100·perf·w + policy_pts − dd_pts, 0, 100) + ≡ 100·clamp(perf·w + policy_pts/100 − dd_pts/100, 0, 1) +``` + +which is the implemented form. This is the only reading consistent with §6.1's +own note that an ordinary (non-drain) `hard` is a **dominant penalty in +`policy_r`** — *not* a forced collapse. Under the literal `[0,1]` clamp a single +`hard` (−40) would drive `raw_r` to 0, i.e. *below* `crash_cap = 7`, erasing the +deliberate distinction between an ordinary `hard` and a floor-crash +(`halt`/drain). The point-scale form keeps a `hard` as a large dominating +subtraction while reserving collapse-to-`crash_cap` for `halt`/drain, and it is +what lets the anti-Sybil weight `w_r` actually bite (a clean low-capital agent +does not saturate to 100). + +## Constants (`CONFIG.scoring`, §6.1) + +| Constant | Default | Meaning / range | +| ----------- | ------- | ---------------------------------------------------------------------------- | +| `k_perf` | 0.5 | Performance sensitivity; with `tanh`, keeps `perf_r ∈ [0, 1]`. | +| `s_roc` | 0.05 | Expected per-round RoC scale inside `tanh(roc/s_roc)`. | +| `c_floor` | 1000 | Capital floor in `w_r`; concavity here is the anti-Sybil lever. | +| `b_clean` | 5 | Bonus (pts) for a clean round (zero `hard`). | +| `p_soft` | 3 | Penalty (pts) per `soft`. | +| `p_hard` | 40 | Penalty (pts) per `hard` — dominates positive performance. | +| `p_halt` | 60 | Penalty (pts) per `halt`. | +| `p_dd` | 20 | Drawdown penalty coefficient (pts). | +| `dd_tol` | 0.15 | Drawdown tolerance band before `dd_pen_r` applies. | +| `epsilon` | 1e-9 | `~0` denominator guard in `roc_r`. | +| `alpha` | 0.4 | EWMA weight on the current round; `∈ (0, 1)`. | +| `score_0` | 20 | Low prior for a new agent. | +| `crash_cap` | 7 | Floor-crash ceiling on `halt`/drain. | + +## Floor-crash invariant + +> `#halt > 0 ∨ drain_r ⇒ Score_r ≤ crash_cap`, applied **after** the EWMA, so a +> catastrophe collapses reputation regardless of a strong prior or a strong raw +> round. `min()` means it only lowers — a score already below `crash_cap` is not +> raised to it. + +An ordinary (non-drain, no-halt) `hard` does **not** floor-crash. It applies a +large dominating penalty in `policy_r` (−`p_hard`) and nothing more. This keeps a +recoverable bad round (e.g. a whitelist REJECT) distinct from an unrecoverable +catastrophe (kill-switch `halt` or a confirmed fund drain). + +## Anti-Sybil / anti-wash + +- **Anti-Sybil.** `w_r = car_r / (car_r + c_floor)` is increasing in capital, so + splitting the same capital across `N` identities gives each clone a strictly + smaller `w_r` — hence a strictly lower score — than the consolidated honest + agent.

Root cause: Bun links static imports eagerly, so the top-level `mock.module('@neondatabase/serverless', …)` in the route/e2e/health tests is process-wide and cannot be undone — it replaced the real driver the integration suites `import { Pool }` from. (The canonical runner sidesteps this by running each suite as its own process; a single-process run did not.) Fix — stop module-mocking the driver; inject the fake pool instead: - lib/db/client.ts: add a test-only `setPoolForTest(pool)` seam beside `resetPool`. Routes call `getPool()`, so injecting there fakes the Neon round-trip without touching the module graph. - api.routes / read-api.e2e: inject a `MockPool` via the seam; drop the driver mock (keep the harmless `server-only` no-op). - health.route: inject the fake for the probe/route tests; the idle-error test now exercises the *real* driver (a real neon `Pool` is a lazy EventEmitter, so `getPool().emit('error', …)` asserts the production construction wiring with no connection opened). Also fix two latent env leaks that surfaced once integration ran in-process: - The route/e2e/health tests used `??=` so they never clobber a real DATABASE_URL (overwriting froze the singleton `ENV.DATABASE_URL` to a fake and broke the real-Neon connectivity probes); the fake is still set when none is present, and restored in afterAll. - .prettierignore: exclude the generated docs/openapi.json so the `api:openapi` generator owns its (byte-deterministic) formatting and Prettier stops reflowing it — `format:check` was failing on the committed file. Verified on real Neon: single-process `bun test` 545 pass / 0 fail; no-DB `bun test` 507 pass / 59 skip / 0 fail; canonical `bun run test` (unit 431 / fuzz 37 / integration 39+2skip / e2e 38) all 0 fail; typecheck, lint, format:check clean. --- .prettierignore | 3 ++ lib/db/client.ts | 15 +++++++ tests/e2e/read-api.e2e.test.ts | 28 ++++++++----- tests/unit/api.routes.test.ts | 35 ++++++++++------ tests/unit/health.route.test.ts | 71 ++++++++++++++++----------------- 5 files changed, 92 insertions(+), 60 deletions(-) diff --git a/.prettierignore b/.prettierignore index d988e1f..4710c2f 100644 --- a/.prettierignore +++ b/.prettierignore @@ -3,3 +3,6 @@ node_modules/ coverage/ bun.lock *.md +# Generated by `bun run api:openapi`; that script owns its formatting (and keeps +# it byte-deterministic for CI diffing), so Prettier must not reflow it. +docs/openapi.json diff --git a/lib/db/client.ts b/lib/db/client.ts index 835a258..16e3e40 100644 --- a/lib/db/client.ts +++ b/lib/db/client.ts @@ -57,6 +57,21 @@ export function resetPool(): void { pool = undefined; } +/** + * Inject a pre-built pool so a test can supply a fake Neon client.

No backend changes. All animations are derived client-side by diffing consecutive P1.5 read-API polls (SWR, no sockets): - capital-flow: diff allocation; greedy outflow->inflow arcs; duration scaled by move size vs router.max_step. - reputation-drop: diff score; crash = cross down to scoring.crash_cap or a status flip out of active; crashed rows redden and fall (FLIP). - red-flash: new REJECT/HALT from the feed, de-duped by event id across polls and within a noisy page (fixes a double-flash on duplicated rows); bounded seen set (pruned to the page, safe on an append-only feed). Precision: exact decimal strings for display/compare (truncate, never round); floats only for geometry. Reduced-motion, error, empty, loading all handled. Tests: lib/arena pure logic ~96% line cov; fuzz over random data + jittery polling; Playwright browser e2e in tests/browser/ (network-scripted, no DB, separate from the bun-test tests/e2e suite).
