+# Public archive agent v0.1
+
+`POST /v0/archive/query` is a deterministic, PUBLIC-only archive query path for
+the Axiom shell. It performs four bounded steps:
+
+```text
+question
+-> frozen public evidence index
+-> deterministic candidate
+-> existing SemeAI Gate
+-> exact candidate for SHOW, otherwise null
+```
+
+It does not call an LLM, network service, private archive, raw archive, or
+online-ingestion source.
+
+## Request
+
+```json
+{
+  "question": "What is the Gate release authority?",
+  "routeContext": "gate",
+  "limit": 5
+}
+```
+
+`question` is required and limited to 256 characters. `limit` is optional and
+must be from 1 through 8.
+
+## Authority boundary
+
+- Retrieval is not truth.
+- Retrieved evidence is marked `UNTRUSTED_DATA`.
+- Generation creates a candidate, not a released answer.
+- The existing SaC/PoR Gate remains the final release authority.
+- Public actions remain `SHOW`, `REVIEW`, and `BLOCK`; their internal states
+  remain `PROCEED`, `NEEDS_REVIEW`, and `SILENCE`.
+- `SILENCE` means release denied, execution withheld, and audit preserved.
+- `releasedAnswer` is the exact candidate only for `SHOW`; it is `null` for
+  `REVIEW` or `BLOCK`.
+- No fallback or warning text substitutes for a held candidate.
+- The release-decision receipt ID is returned as both `decisionReceiptId` and
+  legacy-compatible `receipt_id`.
+- The persisted decision receipt carries an allowlisted `candidate_trace` with
+  candidate ID/hash, route context, and public source IDs. This trace metadata
+  is explicitly not Gate authority and stores no raw question or answer.
+- `executionReceiptId` remains separate and `null` because this endpoint does
+  not execute a downstream action.
+
+When retrieval finds no matching evidence, no candidate is generated and the
+Gate is not invoked. The response states that condition without manufacturing
+an answer or receipt.
+
+## Frozen index
+
+The packaged `semeai_gate_basic/data/axiom_public_evidence.json` mirrors the
+public-site index with SHA-256
+`b2c681a99141ca69125cf3704f3517a00ef8770575cf7ac69371f0ae7a29b9cf`.
+Runtime validation rejects private entries, raw-archive inclusion, online
+ingestion, duplicate source IDs, incomplete provenance, or authority drift.
+
+The public endpoint shares the process-local public-demo abuse guard. It does
+not count against Workspace quota and stores only a short hash of the client
+identity in memory for the active rate-limit window.

+# Axiom public archive pilot v0.1
+
+The first bounded pilot has two deliberately separate layers.
+
+## Local contract dry run
+
+Run:
+
+```powershell
+python tools\run_public_archive_pilot.py `
+  --json-output outputs\axiom_public_pilot.json `
+  --markdown-output outputs\axiom_public_pilot.md
+```
+
+The six fixed tasks cover Gate authority, Skill Forge admission state,
+Repository Evidence Benchmark, Engineering Book receipts, Genesis historical
+admission, and truthful no-evidence behavior. The runner measures local latency,
+source coverage, citation identity, exact candidate/released-answer equality,
+Gate mapping, decision-receipt creation, and absence of an execution receipt.
+
+The output is explicitly labeled `DRY_RUN_NOT_HUMAN_EVALUATION`. It makes no
+claim about production deployment, real-user usability, or private Workspace
+behavior.
+
+## Human pilot (held for release and participants)
+
+After both draft PRs pass independent release authority and production smoke,
+run the same tasks with 3–5 participants. Record:
+
+- whether the participant finds an evidence-backed answer;
+- whether they can identify the cited source and its provenance;
+- whether they correctly distinguish the candidate, Gate decision, and release;
+- whether they understand that `SILENCE` preserves the audit;
+- completion time and any route-context ambiguity;
+- every no-evidence, wrong-source, stale-context, or citation failure.
+
+Do not retain raw participant questions beyond the approved pilot retention
+contract. A human pilot result must remain a separate admitted artifact; the
+local dry run does not auto-admit it.
