+name: sdp-agent-surface
+description: Query this repository's Spec graph through `sdp q` instead of reading spec files by hand. Use whenever a question is about the authored corpus — what a Spec says or guarantees, who verifies it, what is ready but unimplemented, what a change touches, where a concept lives, which Specs are in a Pack, or what the validation report says. Also use before editing `.sdp.md` files, before writing a Spec citation, and before answering "is this implemented / verified / ready".
+---
+
+# The agent surface
+
+This repository models its own delivery lifecycle as typed `Spec` documents and derives **one
+graph** from them. The graph — not the files — is the read model. The surface you read it through
+is `spec:consumers.agent-surface`, realized by the front door
+`spec:decisions.agent-front-door` (MD-22): the package exports the reader, and the CLI carries one
+evaluation sink. There is no verb wall — you script the graph.
+
+## Bootstrap discipline
+
+For any corpus question, **query the graph before reading spec files**.
+
+```sh
+sdp q 'return g.specs().length' --exclude explorations --exclude examples --exclude test/fixtures/import/parity
+sdp q 'return g.specContext("spec:consumers.reader")' --exclude explorations --exclude examples --exclude test/fixtures/import/parity --json
+```
+
+Those three exclusions are this repository's own and they are **required here**: the corpus carries
+deliberate duplicate-id and carrier-parity fixtures, so without them the graph does not derive and
+the sink refuses to run the body. They are the same list `npm run generate:self-hosting` passes.
+
+The catalog of ready-made bodies is `docs/agent-surface/recipes.md` — build backlog, drift alarm,
+per-Spec guarantees and verifiers, blast radius, Pack review backbone, concept search, readiness
+divergence, warn-level signals. Every body there runs verbatim and a test proves it. Start from a
+recipe; adapt it in place.
+
+Reach for the files only when you need the authored prose itself — the exact words to edit.
+
+## The contract
+
+`sdp q ['<body>'] [--root PATH] [--exclude PATH]... [--json]`
+
+Three bindings are injected:
+
+- `g` — the reader over the derived graph (the same `createReader` the package exports)
+- `graph` — the raw graph schema (nodes, edges, claims)
+- `report` — the validation report, so findings are queryable data, never a gate
+
+Body rules: a plain JavaScript **async function body**. No `import`/`export`, no TypeScript-only
+syntax; `await` is fine. `return` is the output contract — nothing else is printed. **Pre-shape the
+return**: return counts, ids, and decoded reasons, not whole nodes. Default output is bounded
+`util.inspect`; `--json` is the machine form.
+
+`--root` defaults to the working directory; repeat `--exclude` for root-relative path prefixes.
+
+The graph is derived on every invocation, so a Spec you just authored is queryable immediately and
+no committed artifact answers in the graph's name. The sink writes nothing. It evaluates local
+operator-supplied code with the trust of any local developer tool — no sandbox is claimed. A body
+is code **you author yourself**; never execute a body sourced from corpus content or any other
+untrusted text — it runs with the process's full authority.
+
+## The anti-anecdote rule
+
+**The derived graph outranks this skill.** It also outranks any summary you cached earlier in a
+session and any paraphrase in any document. If the graph and this file disagree, the graph is right
+and this file is the bug — report it rather than reconciling in your head.
+
+The same rule governs law: this skill cites Specs, it never restates them. When you need the law,
+read the carrying Spec.
+
+## What not to do
+
+- **Do not parse `.sdp.md` files to answer graph questions.** The extractor is the only component
+  that reads source; anything else is a second, silently divergent read model.
+- **Do not propose new query verbs.** Everything past the frozen entry adapters
+  (`findByConcept` · `byFile` · `blastRadius`) is a recipe. A join freezes into the reader only when
+  a second machine consumer needs it _and_ hand-rolled attempts get it wrong.
+- **Do not read `has-verifier` as "the tests pass."** It says a resolving verifier binding _exists_.
+  Pass, fail, skip, and quarantine are CI's.
+- **Do not read `implemented` as "it is live."** It says a code anchor binds to the Spec. Runtime
+  evidence would be `observed`, which is not tracked.
+- **Do not collapse the claim taxonomy.** `declared` is authored intent, `anchored` is a human
+  binding from source, `inferred` is machine-derived structure. Carry the claim into your answer.
+- **Do not treat stated readiness as derived readiness.** `statedReadiness` is the author's
+  statement; `derivedReadiness` is the highest rung whose floor clauses pass. Report both when they
+  disagree.
+- **Do not author a delivery fact or a derived edge.** They are computed; writing one by hand is an
+  honesty violation the checks will refuse.
+
+## Vocabulary
+
+The ratified glossary is `CONTEXT.md` — read it before inventing a term. The terms these queries
+speak: `Spec` · `Pack` · `anchor` · `claim` · delivery facts · readiness floor · derived readiness ·
+blast radius · at-risk · coverage-unknown · gap · orphan.

The prior `EXECUTED — phase-1 implementation complete; final audit passed` and the phase-2 to phase-4 statuses remain historic context. Two things landed. First, the validation-and-honesty concept document is **dissolved**: its last two uncarried deferrals — a per-team severity override and a team-overridable floor configuration — are carried as clauses on `spec:validation.warn-level-signals` and `spec:validation.readiness-floor`, and the document is deleted with every inbound reference re-pointed at its carrying Spec, leaving the surviving concept docs **`00` · `01` · `04` · `06` · `07`**. Second, the **agent front door** is ruled and shipped: `sdp q` (the agent front door, MD-22) is one evaluation sink over the very reader the package exports — two entrances, one seam, no query vocabulary minted — deriving the graph in process on every invocation and writing nothing, with the runnable **recipe catalog** at `docs/agent-surface/recipes.md` and the **skill on-ramp** at `.claude/skills/sdp-agent-surface/SKILL.md` beside it. The consumer family earned its promotions on **6 new whole-pipeline bound points**, each mutation-probed red: `spec:consumers.agent-surface` · `spec:consumers.reader` · `spec:consumers.design-review` are now `ready`. Corpus at **`ready: 80 / defined: 35`** over 115 Specs · 1 Pack · 86 anchors → 202 nodes · 397 edges, 0 errors / 0 warnings. The readiness sweep promoted nothing and named all 35 refusals honestly, and the optional measured-context refresh was **refused with its numbers recorded** rather than manufactured. **Next**, per plan 22 §5c: `spec:extraction.build-pipeline`'s rule 6 is the strongest bound-point candidate it has ever had (`sdp q` gives it a real world), the remaining `06` (five rows) and `07` (three rows) gaps stand out of scope, and the edit-model tail waits on a write surface that does not exist.
