Subject: [PATCH 01/15] docs(as-00): freeze AS baseline and document non-claims

Record the 1.2.0 admissibility-stack baseline, ADRs for boundary/pilot/reconstruction, and explicit non-claims in limitations and threat model so AS hardening cannot be read as truth or efficacy certification.

+# ADR 0001 — Admissibility boundary
+
+## Status
+
+Accepted (AKTA-AS-00)
+
+## Context
+
+AKTA sits between model output and scientific action. Integrators sometimes treat gate decisions as truth certification, SCOPE replacement, or a learning loop over pilot outcomes. The AS hardening workstream needs an explicit boundary before adding reconstructable artifacts and pilot modes.
+
+## Decision
+
+AKTA is an **admissibility boundary**: it admits, refuses, or routes a proposed scientific action under pinned policy, evidence context, and deployment profile.
+
+AKTA does **not**:
+
+1. Certify scientific truth, correctness, or institutional efficacy
+2. Replace SCOPE reviewer identity verification, grant lifecycle, or signing
+3. Replace PF-Core runtime enforcement or PCS-Core release packaging as sibling systems of record
+4. Run general reinforcement learning or update policy from pilot outcome metrics
+5. Authorize P7 fully autonomous scientific operator behavior (taxonomy-only; runtime refused)
+
+Pilot metrics (AS-07) are privacy-preserving operational aggregates for disagreement, blocking rates, and reconstruction completeness — not efficacy scores that feed back into policy learning.
+
+## Consequences
+
+- Docs and ADRs must restate these non-claims at release boundaries (AS-08).
+- New schemas/CLIs are additive; frozen PROTOCOL v1.0 required fields remain unchanged.
+- Fail-closed institutional pins (including placeholder release signers) stay fail-closed.

+# ADR 0002 — Pilot modes
+
+## Status
+
+Accepted (AKTA-AS-00; implemented in AS-05)
+
+## Context
+
+Pre-AS pilot stages (`stage1_shadow`, `stage2_draft_only`, `stage3_validation`) underspecify tool restrictions and do not match the five institutional pilot modes required for hardening. REST/MCP also use a separate “mode” namespace for deployment identity.
+
+## Decision
+
+Introduce five first-class `PilotMode` values:
+
+| Mode | Hard restrictions |
+|------|-------------------|
+| `retrospective_reconstruction` | No live tool execution; reconstruct/validate only |
+| `prospective_shadow` | Full evaluate + record; `shadow=true`; must not drive allow/execute side effects; comparison record required |
+| `read_only_support` | Mutating/execution tools blocked; analysis/query only |
+| `execution_adjacent` | Draft/propose/review tools allowed; direct execution tools blocked |
+| `bounded_execution` | Full stack profile + trust pins required; tool allowlist from policy; fail closed on missing trust |
+
+Legacy `PilotStage` / `AKTA_PILOT_STAGE` aliases map into these modes. Unknown values fail closed.
+
+### Policy profile binding
+
+Each mode loads a profile under `policy/pilot_modes/` validated by `pilot_mode_profile.schema.json`. Profiles declare tool-effect allow/deny classes and trust requirements.
+
+### Shadow isolation
+
+`prospective_shadow` decisions must set `operational_influence: false`. Shadow responses must never authorize execution via grant/export paths that enable side effects.
+
+### CLI naming
+
+- `akta gate --mode <pilot_mode>` — pilot mode (this ADR)
+- REST service `--mode` — deployment identity (unchanged; different namespace)
+
+Default without `--mode` preserves pre-AS-05 behavior (retrospective-compatible / current `stage1_shadow` env default).
+
+## Consequences
+
+- AS-05 enforces mode gates before tool-resolution side effects.
+- AS-07 metrics consume shadow comparison artifacts.
+- Documentation must disambiguate pilot mode vs REST deployment mode.

+# ADR 0003 — Artifact immutability and reconstruction
+
+## Status
+
+Accepted (AKTA-AS-00; implemented across AS-01/03/07/08)
+
+## Context
+
+Institutional pilots require that an admissibility decision can be reconstructed from frozen evidence and pinned policy. Outcome linkage must not rewrite the original verdict.
+
+## Decision
+
+1. **Pinned material inputs.** Decisions/records bind digests for question, evidence report, claim set, proposed action, VSA decision-time bundle, policy/overlay/tool-registry hashes, tool, action class, and IDs (AS-01 binding set).
+2. **Decision basis.** Structured `decision_basis` cites loaded policy clauses and evidence gaps; constructive `next_admissible_steps` must not be silently emptied on blocks (AS-03).
+3. **Immutable historical artifacts.** Original `admissibility` and binding digests are immutable after emission. Outcome links are append-only (`outcome_ref` events / `integrations.outcome_refs[]`) with `verdict_mutation: false` (AS-07). Attempts to rewrite admissibility fail closed (`policy_block` / schema failure).
+4. **Reconstruction.** `akta reconstruct --release …` rebuilds a reconstruction report from a release bundle using the same library as demo/verify scripts (AS-08). Frozen evidence + pinned policy must be sufficient to explain the decision.
+
+## Consequences
+
+- New artifact types get dedicated schema files; existing decision/record schemas gain optional additive fields only.
+- Exporters (SCOPE trigger, PF, PCS) bind `decision_id`/`record_id` and digests; tamper/mismatch fails closed when mode requires it.
+- Pilot metrics must not include raw private evidence text.

+# AKTA Admissibility-Stack (AS) Baseline Freeze

+| Field | Value |
+|-------|-------|
+| Package | `akta-protocol` |
+| Version | `1.2.0` |
+| Base commit | `4d23944657bb4a27f4056f03e4adbb9873d131a2` |
+| Protocol freeze | [`PROTOCOL_v1.0.md`](PROTOCOL_v1.0.md) |
+| Recorded at | 2026-07-24 |
+
+## Toolchain
+
+| Component | Version / command |
+|-----------|-------------------|
+| Python | `>=3.10` (baseline host: 3.13.11) |
+| Install | `make install` → `pip install -e ".[dev,security]"` |
+| Unit / contract tests | `make test` → `pytest tests/ skills/...` |
+| Default CI | `make ci` |
+| Bench regression | `make eval-bench-v1` |
+
+## Reproducible commands (clean checkout)
+
+```bash
+git checkout 4d23944657bb4a27f4056f03e4adbb9873d131a2
+python -m pip install -e ".[dev,security]"
+make ci
+make eval-bench-v1
+```
+
+Record stdout/exit codes in the PR body for AS-00. Default `make ci` is offline (no sibling repos required). Live SCOPE/PF/PCS conformance remains opt-in via sibling env vars.
+
+## Protocol / benchmark claims (snapshot)
+
+- Frozen protocol text: [`PROTOCOL_v1.0.md`](PROTOCOL_v1.0.md).
+- Decision/record schemas already allow `additionalProperties: true` — AS work adds optional fields and **new** schema files; it does not rewrite frozen required fields.
+- Bench failure classes remain F01–F15 in [`failure_class_taxonomy.md`](failure_class_taxonomy.md) / `evals/graders.py`.
+- **Known debt (AS-04):** historical reports and some fixtures use `F1_` vs `F01_` naming drift. Mapping normalizes in the uniform-failure layer only; historical eval reports are not rewritten.
+
+## Spine extended (not replaced)
+
+| Component | Location |
+|-----------|----------|

+| Release pins | `policy/release_pins.yaml` + `akta/release_pins.py` |
+| Pilot stages (pre-AS-05) | `akta/pilot_workflow.py` |
+
+## Non-claims (baseline)
+
+AKTA admits or refuses a proposed scientific action under pinned policy. This workstream does **not**:
+
+- Certify scientific truth or institutional efficacy
+- Replace SCOPE reviewer identity, grant lifecycle, or signing
+- Run general reinforcement learning or learn policy from pilot outcomes
+- Authorize P7 fully autonomous scientific operators
+- Weaken institutional fail-closed behavior for placeholder release signers
+
+See ADRs under [`adr/`](adr/) and updates in [`limitations.md`](limitations.md) / [`threat_model.md`](threat_model.md).

 # AKTA Limitations
 
+Package baseline: **1.2.0**. Historical sections below retain release-era limits for integrators on older docs paths.
+
+## Admissibility-Stack hardening (AS-00–08 / 1.2.x)
+The AS workstream hardens reconstructable admissibility, pilot modes, and outcome linkage. It explicitly does **not**:
+
+- Certify scientific truth, correctness, or institution-wide scientific efficacy
+- Replace SCOPE reviewer identity, grant lifecycle, or cryptographic signing
+- Learn or update policy from pilot outcome metrics (no RL / policy-learning loop)
+- Authorize P7 fully autonomous scientific operators
+- Claim that shadow-mode outputs may drive operational allow/execute side effects
+- Treat placeholder release signers or incomplete stack pins as institutional pass
+
+### AS non-claims (operator-facing)
+
+- **Admissibility ≠ truth**: gate decisions admit/refuse proposed action under policy; they do not validate scientific claims
+- **Reconstruction ≠ reproducibility of nature**: reconstruction verifies artifact/policy binding integrity, not experimental replication
+- **Pilot metrics ≠ efficacy**: aggregates cover sufficiency rates, block/allow/review rates, disagreement, and reconstruction completeness only
+- **Known debt**: bench F-class naming drift (`F1_` vs `F01_`) is normalized in the uniform-failure mapper only; historical eval reports are not rewritten (AS-04)
+
+See [`as_baseline.md`](as_baseline.md) and [`adr/`](adr/).

+## AS workstream non-claims (threat posture)
+
+The Admissibility-Stack hardening (AS-00–08) adds digest bindings, stack profiles, decision basis, uniform failures, pilot modes, outcome refs, and reconstruction CLI. It does **not** claim:
+
+- Defense against model prompt injection or model truthfulness
+- That pilot outcome linkage improves scientific quality or efficacy
+- That shadow evaluations may authorize execution
+- That incomplete institutional pins (placeholder signers, missing siblings) are acceptable under `bounded_execution` / institutional release
+- Replacement of SCOPE/PF/PCS as systems of record for identity, runtime proof, or release packaging
+
+Residual risk for forged records outside the AKTA export path, misconfigured production env, and incomplete sibling checkouts remains as below.
+
+## AS controls (1.2.x)
+
+- Binding digests on decisions/records; reconstruction CLI verifies release bundles
+- Stack profile validation against institutional pins (fail closed on placeholder signers / missing siblings when required)
+- Pilot-mode allowlists and shadow isolation (`operational_influence: false`)
+- Uniform failure surfaces additive to local reason codes
+- Append-only outcome refs; metrics exclude raw evidence text
+
+These controls harden reconstructability and pilot boundaries. They do not upgrade `runtime_observed` adapter results into cryptographic or institutional guarantees.

Subject: [PATCH 02/15] feat(as-01): add binding digests and harden VSA import

Introduce akta_binding_set schema and gate/record bindings so decisions carry reconstructable digests, and fail-close VSA import on digest mismatch or ambiguous evidence refs.

+# Stack Profile
+
+Machine-readable declaration of compatible VSA / AKTA / SCOPE / PF-Core / PCS / Scientific-Memory versions (AS-02). Package baseline: **1.2.0**.
+
+## Role
+
+| Artifact | Role |
+|----------|------|
+| `stack_profile.json` | Portable declaration of intended stack versions |
+| `policy/release_pins.yaml` | Institutional pin source of truth |
+| `policy/scope_compatibility_manifest.json` | SCOPE/contracts compatibility |
+| `policy/shared_contracts_pin.json` | Contracts wheel/manifest digests |
+
+Unsupported combinations fail closed. Incomplete institutional pins and placeholder release signers remain fail-closed under institutional / `bounded_execution` profiles. Validation does not imply sibling systems are live or certified.
+## Schema
+
+See [`schemas/stack_profile.schema.json`](../schemas/stack_profile.schema.json).
+
+## CLI
+
+```bash
+akta validate-stack-profile stack_profile.json
+```
+
+Exit non-zero when the profile is unsupported, missing required components, or disagrees with release pins / package `__version__`.
+
+## Python
+
+```python
+from akta.stack_profile import validate_stack_profile
+
+result = validate_stack_profile("stack_profile.json")
+assert result["ok"]  # or inspect result["errors"]
+```
+
+## Fixtures
+
+`tests/fixtures/as02/` — valid institutional, unsupported combo, missing components.

Subject: [PATCH 05/15] feat(as-04): map local reasons to uniform failure
 classes

Add a ten-class uniform failure surface (additive to local codes) and REST error mapping so integrators share a stable failure vocabulary without rewriting historical F-class reports.

+## Uniform mapping (AS-04)
+
+Bench F-classes (F01–F15) remain the regression taxonomy for AKTA-Bench and adversarial transitions. Runtime / API failures additionally map into ten **uniform classes** while preserving the local reason code:
+
+| Uniform class | Typical local sources |
+|---------------|----------------------|
+| `invalid_input` | schema validation, malformed requests |
+| `insufficient_evidence` | evidence rules, `F01_*` / legacy `F1_*` |
+| `policy_block` | profile refuse, pilot mode, policy integrity |
+| `review_required` | review gate |
+| `authorization_denied` | grant / authorization failures |
+| `runtime_constraint_violation` | tool registry / runtime limits |
+| `verification_failed` | digest / grant verification failures |
+| `verification_indeterminate` | inconclusive verification |
+| `external_dependency_failure` | sibling / external adapter failures |
+| `outcome_unresolved` | missing or pending outcome linkage |
+
+Mapping lives in `akta/failure_mapping.py`. Historical eval reports are **not** rewritten; `F1_` → `F01_` normalization happens in the mapper only. REST responses keep prior `error_code` and may add additive `failure` / `failures[]` fields.
+
+Uniform classes explain refusal/routing under policy. They do **not** certify scientific truth, replace local reason codes, or upgrade adapter `runtime_observed` results into institutional guarantees.
+
+Schema: [`schemas/uniform_failure.schema.json`](../schemas/uniform_failure.schema.json). Fixtures: `tests/fixtures/as04/`.

 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
+## [Unreleased] — Admissibility-Stack hardening (AS-00–08) on 1.2.0
+
+Additive hardening atop package **1.2.0**. Does not rewrite frozen PROTOCOL v1.0 required fields.
+
+### Added
+
+- Baseline freeze + ADRs (`docs/as_baseline.md`, `docs/adr/0001`–`0003`)
+- Binding set schema and decision/record `bindings` digests (AS-01)
+- `stack_profile` schema/validator and `akta validate-stack-profile` (AS-02)
+- `decision_basis` structured artifact (AS-03)
+- Uniform failure mapping + `failure` / `failures[]` surfaces (AS-04)
+- Five `PilotMode` values, `policy/pilot_modes/`, `akta gate --mode` (AS-05; distinct from REST deployment `--mode`)
+- SCOPE/PF/PCS binding hardening and AS-06 fixtures (AS-06)
+- Append-only `outcome_ref`, `akta link-outcome`, `akta export-pilot-metrics` (AS-07)
+- `akta reconstruct`, operator/reviewer pilot guides (AS-08)
+
+### Changed
+
+- VSA import prefers `vsa_bundle` and fail-closes on digest mismatch / ambiguous refs
+- Legacy `PilotStage` / `AKTA_PILOT_STAGE` map into PilotMode (unknown values fail closed)
+
+### Notes
+
+- Additive CLI/API only; default `gate`/`record`/`export`/`eval` remain compatible when new flags are omitted
+- Placeholder release signers remain fail-closed under institutional stack profiles
+- Pilot metrics are operational aggregates only — not institution-wide scientific efficacy scores
+- Admissibility decisions are not scientific truth certification (ADR 0001)
+
 ## [1.2.0] - 2026-07-23

+# Operator pilot guide
+
+How to run an institutional AKTA pilot without treating gate outputs as truth certification or execution authority.
+
+## Non-claims
+
+- AKTA admits/refuses proposed actions under pinned policy — it does not certify scientific truth or efficacy.
+- Shadow mode must not drive operational allow/execute side effects.
+- Pilot metrics are operational aggregates, not institution-wide scientific efficacy scores.
+
+## Pilot modes (AS-05)
+
+These are **PilotMode** values for `akta gate --mode`. They are not REST service deployment modes (`development-local` / `pilot-service` / `institutional-service`) and not legacy `PilotStage` enum names (those aliases map into PilotMode; unknown values fail closed).
+
+| Mode | Operator use |
+|------|----------------|
+| `retrospective_reconstruction` | Rebuild/validate historical releases only |
+| `prospective_shadow` | Evaluate + record with `shadow=true`; compare to human decisions; must not drive allow/execute side effects |
+| `read_only_support` | Analysis/query assistance; no mutations |
+| `execution_adjacent` | Draft/propose/review; no direct execution |
+| `bounded_execution` | Requires stack profile + trust pins; tool allowlist; fail closed |
+
+```bash
+akta gate --ai-text "..." --tool analysis.literature_summary --mode prospective_shadow --out decision.json
+akta record --decision decision.json --out akta_record.json
+akta validate-stack-profile stack_profile.json
+```
+
+## Release reconstruction
+
+```bash
+akta reconstruct --release action_release/ --out reconstruction.json
+```
+
+Expect `ok=true`, bindings present, and checksums for the bundle.
+
+## Outcomes and metrics
+
+```bash
+akta link-outcome --record akta_record.json --outcome-ref outcome_ref.json --out akta_record_linked.json
+akta export-pilot-metrics --records records/ --out metrics.json
+```
+
+Outcome links are append-only and must not change `admissibility`.
+
+## Checklist
+
+1. Pin policy / overlays / tool registry; record `bindings` digests
+2. Choose pilot mode explicitly; default without `--mode` preserves pre-AS-05 behavior
+3. For institutional / `bounded_execution`, run `akta validate-stack-profile` (incomplete pins and placeholder release signers remain fail-closed)
+4. Export SCOPE trigger → PF → PCS with binding fields intact
+5. Run `akta reconstruct` before treating a release as pilot-complete
+
+See [stack_profile.md](stack_profile.md), [adr/0001-admissibility-boundary.md](adr/0001-admissibility-boundary.md), [adr/0002-pilot-modes.md](adr/0002-pilot-modes.md), and [limitations.md](limitations.md).

+# Reviewer pilot guide
+
+Guidance for human reviewers consuming AKTA review triggers and shadow comparisons during pilots.
+
+## What to review
+
+1. **Decision reason + decision basis** — policy clauses, missing evidence, contradictions, next admissible steps
+2. **Bindings** — digests for evidence/VSA bundle, policy/overlay/tool registry, IDs
+3. **Uniform failure** (when present) — `uniform_class` plus preserved `local_reason_code`
+4. **Pilot mode flags** — `shadow` / `operational_influence` must be false for shadow paths that must not authorize execution
+
+## Shadow disagreement
+
+When AKTA runs in `prospective_shadow`, record a comparison artifact (human vs AKTA). Disagreement feeds pilot metrics; it does not auto-change policy.
+
+## SCOPE handoff
+
+Review triggers bind `decision_id` / `record_id` and policy hashes. Do not approve grants that omit these bindings in institutional pilots.
+
+## Non-claims
+
+- Reviewer approval via SCOPE is still required for authorization-gated actions
+- AKTA does not replace IRB/biosafety/EHS review
+- Reconstruction verifies artifact integrity, not experimental replication in nature
+- Uniform failure classes and local reason codes explain refusal/routing; they do not certify scientific truth
+
+## Acceptance questions
+
+- Can another operator reconstruct this decision from the release bundle (`akta reconstruct`)?
+- Are outcome links append-only without rewriting admissibility?
+- Did shadow outputs stay non-operational (`operational_influence: false`)?
+
+See [operator_pilot_guide.md](operator_pilot_guide.md), [failure_class_taxonomy.md](failure_class_taxonomy.md), and [adr/0003-artifact-immutability-and-reconstruction.md](adr/0003-artifact-immutability-and-reconstruction.md).

 Scientific authority transfer occurs when an AI output changes what a scientific system is more likely to believe, test, modify, prioritize, execute, or publish.

 ## The problem
 
 AI-for-science systems are crossing from reasoning to action. Models summarize literature, interpret evidence, draft protocols, recommend experiments, call tools, and prepare execution-adjacent workflows. Each of these outputs can change what science does next — even when the model frames the output as informal, preliminary, or "just a suggestion."
