+### §12.10 — Nova-idp Identity Layer (v1.28, current)
+
+Nova owns its identity layer end-to-end. Two (optionally three) Lambda
+functions + four DynamoDB tables + one KMS asymmetric signing key + one
+kyverno-json ABAC policy. **No Cognito, no IAM Identity Center (INV-15).**
+The `nova-cli` Lambda layer carries the Nova wheel + `argon2-cffi` +
+`cryptography` + `pyjwt` + the `kj` Go binary, making the same code
+importable in both the CLI and the Lambda (REQ-329 dual-use, NFR-7).
+
+**Components:**
+
+- `nova-idp-auth` Lambda — sign-up, sign-in, session creation. Argon2id
+  password hashing (D-228: bundled abi3 wheel; fail-closed on
+  `ImportError`, no pure-Python fallback). DynamoDB: `nova-users`
+  (PK `user_id`, Argon2id `password_hash`), `nova-sessions` (PK
+  `session_id`, TTL `expires_at`), `nova-password-resets` (PK
+  `reset_token`, TTL 15m). Function URL with IAM auth.
+- `nova-idp-token-vend` Lambda — accepts a PAT (or session token),
+  validates revocation (`nova-pats.GetItem(jti, ConsistentRead=True)` —
+  D-229, 60s SLO), evaluates the kyverno-json ABAC policy at
+  `platform/abac/token-vend.policy` (D-227, INV-17), KMS-signs an
+  ECDSA P-256 JWT (`ES256`), converts DER→raw ECDSA signature (RFC 7515
+  §3.1.3), returns the OIDC token. The `policy_version` (git SHA,
+  D-231) is recorded in every `token.vend.allowed/denied` audit event.
+- `nova-idp-jwks` Lambda (optional, separation of concerns) — function
+  URL with `AuthType: NONE` (public key only), `Cache-Control: max-age=3600`.
+  `kms.get_public_key` → DER SPKI → JWK via `cryptography`. Custom
+  domain + WAF via CloudFront is OPTIONAL (`--public-jwks-domain` flag
+  on `nova idp setup`, D-230).
+- `nova-pats` DynamoDB table — PK `jti`, GSI1 `sub` (list PATs for
+  user), GSI2 `pat_hash` (lookup by hash). Only the hash stored (not
+  raw PAT, REQ-343). Revoked PATs retained for audit.
+
+**CLI surface (`nova` package, greenfield):**
+
+- Entry point: `[project.scripts] nova = "nova.cli:main"` (argparse-only,
+  no click/typer — repo convention). `nova/cli.py` auto-discovers
+  `nova/<module>.py` subcommands via `pkgutil.iter_modules`, dispatches,
+  emits the `cli.invocation` audit event (INV-12) with `mode`,
+  `selection_reason`, `credential_type`, `command`, `args`.
+- Each `nova/<module>.py` is ≤50 lines, delegates to `core/` (CAP-034
+  AST scan). Subgroups: `nova auth login/revoke/status`, `nova idp
+  setup --check/--apply/--verify`, `nova init`, `nova apply --local`.
+- `core/mode_resolver.py` — flag → env (`NOVA_CLIENT_MODE`) → credential
+  type → `sys.stdin.isatty()` (D-226). CLI-only; Lambdas don't resolve
+  modes. Property-tested with `hypothesis` (REQ-349).
+- `core/env.py:+synthesize_local_env()` — synthesizes a local env dict
+  from a contract + `--local` flag (REQ-330). No cloud provisioning.
+
+**Packaging (NFR-6, CAP-035):**
+
+- CI publishes a wheel to CodeArtifact AND a Lambda layer with identical
+  version strings on every merge affecting `core/`/`adapters/`/`nova/`.
+  Version mapping recorded in SSM `/nova/layer/nova-cli/version`.
+  If either publish fails, the merge is blocked (REQ-323).
+- `nova cli-action` composite action at
+  `.github/actions/nova-cli/action.yml`, referenced by both GitHub +
+  Gitea (`uses: continuous-intelligence/acdl/.github/actions/nova-cli@v1.28`).
+  Python 3.12 pinned. Byte-identical behavior verified by CI matrix
+  (REQ-326, NFR-11).
+
+**Data flows:**
+
+1. Sign-up → `nova-idp-auth` → Argon2id → `nova-users` PutItem → session
+   → `nova-sessions` PutItem → return session token.
+2. Token vend (hot path) → `nova-idp-token-vend` → `nova-pats` strong
+   read (revocation) → kyverno-json ABAC eval → if allow → KMS sign →
+   DER→raw → return OIDC JWT. Audit at every step.
+3. JWKS fetch → `nova-idp-jwks` → `kms.get_public_key` → DER→JWK →
+   `{"keys":[...]}`. Cached 1h at CloudFront (if custom domain) / client.
+4. PAT revoke → `nova auth revoke --pat <jti>` → `nova-pats.UpdateItem(
+   status=revoked)` → audit. Strong read on next vend → 403 (within 60s).
+
+**`nova idp setup` (REQ-340, NFR-10):** generates a CloudFormation
+template (raw dict → JSON, no troposphere dep), presents for review
+(`$PAGER` + resource summary), requires explicit `y/N` approval before
+`cloudformation deploy --capabilities CAPABILITY_IAM`. `--check` reports
+prerequisites + IAM policy delta; `--verify` runs the KMS round-trip
+test. New IAM grants required: `cloudformation:*`, `codeartifact:*`.

-or a separate `.ciagent/` inside the consumer repo?

-matches `run.md` Step 0 multi-project mode.
 
-**Confidence:** 0.95. **Decision:** D-206.
+### Q-P2 — The spec's "locked inputs" (D-NEW-26, kj engine, Nova-idp, INV-63/64/65, CAP-025..030, REQ-001..031) don't exist in the repo. How to handle?
 
-### Q2 — Is the bootstrap `NOVA_AWS_*` key the root key or the spike-runner key?
+**Resolution:** Author them fresh in this milestone's CLARIFY/RESEARCH as
+**D-226..D-231, INV-12..17, CAP-033..038, REQ-323..353**. The `kj` engine
+is mapped to the existing **kyverno-json** engine (INV-4 swappable) — no
+new engine is built. CAP/INV/REQ IDs are re-allocated to avoid collisions
+with shipped history (CAP-025..032 and INV-1..11 are blockchain/pilot).
+**Confidence:** 1.0 (user-confirmed — "Re-map to v1.28"). **Decision:** D-227 (kj→kyverno-json), plus the ID-allocation block in REQUIREMENTS.md.

-(pilot scope).
-
-**Confidence:** 0.90. **Decision:** D-207.
-
-### Q3 — Which AWS account does the pilot use: `581513795199` (existing) or a dedicated pilot account?
-
-**Ambiguity:** The user said "assume 581513795199." But the env JSONs
-all show `account_id: "000000000000"` (placeholder). Does the pilot
-bind all env JSONs to `581513795199`, or only `dev` (with qa/prod/dr
-left placeholder until a real multi-account landing zone exists)?
-
-**Resolution:** Bind `dev` to `581513795199` for the pilot
-(D-203, established in SPECIFY). The `qa`/`prod`/`dr` env JSONs remain
-placeholder `000000000000` this milestone — the pilot runs in `dev`
-(autonomous, no HITL gate). Multi-account landing zone (qa/prod/dr on
-separate accounts) is a future milestone. REQ-319 (env-JSON wiring)
-updates `dev.json`'s `state_backend.bucket` to

-qa/prod/dr get the `state_backend.bucket` update but keep placeholder
-`account_id` (the pilot-readiness policy REQ-320 blocks apply on
-placeholder accounts — so qa/prod/dr apply is blocked by design until
-the accounts are bound).
-
-**Confidence:** 0.92. **Decision:** D-208.
-
-### Q4 — Does "all types of securities" mean all types in v1.26, or equities-only pilot with others deferred?
-
-**Ambiguity:** The user said "stock market built on homegrown blockchain
-offering all types of securities." This could mean equities + bonds +
-derivatives + options all in v1.26, or equities-only pilot with others
-deferred (the recommended scope from the plan).
-
-**Resolution:** Equities-only pilot (D-200, established in SPECIFY).
-Bonds/derivatives/options have very different settlement models (T+1
-for equities; T+2 for bonds; derivatives vary; options exercise
-models). A pilot should demonstrate the Nova platform's policy gates
-over a real estate — equities (T+1) is the simplest. "All types of
-securities" is the *product vision*; v1.26 is the *pilot* (equities
-first). The roadmap documents the deferral.
-
-**Confidence:** 0.85. **Decision:** D-200 (reaffirmed).
-
-### Q5 — Is the homegrown blockchain a real consensus protocol or a minimal PoA ledger?
-
-**Ambiguity:** "Homegrown blockchain" could mean a full consensus
-protocol (multi-validator BFT) or a minimal PoA ledger (single
-validator, append-only).
-
-**Resolution:** Minimal PoA ledger (D-201, established in SPECIFY).
-Single validator (config-driven), append-only blocks, SHA-256 hash
-chain, deterministic block production. Settlement finality = block
-commit. Multi-validator BFT is a future milestone. The pilot's purpose
-is to exercise the Nova platform's deploy/policy/attestation gates over
-a real consumer — the chain needs to be real enough to record
-transactions, not to solve Byzantine consensus.
-
-**Confidence:** 0.88. **Decision:** D-201 (reaffirmed).
-
-### Q6 — Does the pilot's `terraform apply` actually run, or is it `--plan-only`?
-
-**Ambiguity:** The platform's `run_platform.sh` defaults to
-plan-only (no apply). The `deploy.yml` workflow's `mode` input can be
-`full` (apply) or `plan-only`. Does the pilot actually `terraform apply`
-(creating real AWS resources for the blockchain exchange), or does it
-stop at plan?
-
-**Resolution:** The pilot runs `mode: full` (apply) for `dev` only.
-The apply creates real AWS resources (ECS for the matching engine,
-DynamoDB for the ledger, S3 for block storage) in account
-`581513795199`. `qa`/`prod`/`dr` are blocked by the pilot-readiness
-policy (REQ-320) until their accounts are bound (D-208). The apply is
-autonomous for `dev` (no HITL gate; confidence threshold 0.50). The
-`ai.decision.made` + `attestation.recorded` events land in the Decision
-Ledger — but `dev` attestation is autonomous (no human approver), so
-only `ai.decision.made` fires for `dev`.
-
-**Confidence:** 0.90. **Decision:** D-209.
-
-### Q7 — What AWS resources does the blockchain exchange contract declare?
-
-**Ambiguity:** The `contract.yaml` declares the exchange's
-infrastructure. What specific AWS resources? The platform's adapter
-maps contract infrastructure blocks to Terraform. What stack types
-does the blockchain exchange use?
-
-**Resolution:** The pilot contract declares 3 infrastructure blocks:
-(1) `ecs` (Fargate service for the matching engine + settlement
-service — the platform's existing `microservice` module pattern), (2)
-`dynamodb` (the ledger table — single-table, PK `block_index`), (3)
-`s3` (block storage — one object per block, key `blocks/{index}.json`).
-The adapter's `TYPE_MAP` already covers `aws_ecs_service`,
-`aws_dynamodb_table`, `aws_s3_bucket` (existing L1 primitives). No new
-adapter stack types needed for the pilot. The contract's
-`infrastructure` block references these by module name (`microservice`
-for ECS, `dynamodb` for the table, `s3` for the bucket).
-
-**Confidence:** 0.82. **Decision:** D-210.
-
-### Q8 — Does the outcome-backfill emitter (REQ-317) change the PCR schema?
-
-**Ambiguity:** REQ-317 wires `apply.completed`/`apply.failed` →
-`fact_decision.outcome`. Does this touch the `PolicyCheckResult` schema
-(PCR) — the v1.25 moat that must not change?
-
-**Resolution:** No. The outcome backfill touches the *metrics cold
-store* (`fact_decision` table in `metrics/nova_metrics.db`), not the
-PCR schema. The PCR schema (`schemas/policy_check_result.schema.json`)
-is unchanged. The backfill reads run-manifest events (not PCRs) and
-updates the decision's outcome column. This respects the v1.25 hard
-constraint: "DO NOT change `schemas/policy_check_result.schema.json`."
-
-**Confidence:** 0.95. **Decision:** D-211.
-
-### Q9 — Does the consumer repo need its own test suite + CI, or does the platform's CI cover it?
-
-**Ambiguity:** The consumer repo (`nova-blockchain-exchange`) has app
-code (blockchain, engine, settlement). Does it run its own tests in
-its own CI, or does the platform's `platform-test.yml` cover it?
-
-**Resolution:** The consumer repo runs its own tests in its own CI
-(`nova-blockchain-exchange/.github/workflows/ci.yml` — lint + pytest on
-the blockchain/engine/settlement code). The platform's
-`platform-test.yml` covers the *platform* repo only (it validates
-contracts against the schema, runs adapter tests, etc.). The consumer
-repo's `deploy.yml` invocation triggers the platform's deploy workflow
-(which runs `run_platform.sh`); the platform's policy + attestation
-gates apply over the consumer's apply. The consumer's unit tests
-(chain integrity, order matching, settlement) are the consumer's
-responsibility. REQ-310..312 include consumer-side tests
-(`test_block.py`, `test_order_book.py`, `test_settlement.py`).
-
-**Confidence:** 0.88. **Decision:** D-212.
-
-### Q10 — Is the milestone a feature milestone (tags on v1.25.x) or a major milestone (breaking schema changes)?
-
-**Ambiguity:** v1.26 introduces a 2nd project (multi-project mode) +
-new requirements. Does this break any schema (→ major milestone, tags
-on v1.26.x), or is it a feature milestone (tags on v1.25.x)?
-
-**Resolution:** Feature milestone. No schema breaks: the PCR schema is
-unchanged (D-211); the contract schema is unchanged (the consumer
-contract validates against the existing
-`schemas/contract.schema.json`); the env JSON gains a real
-`account_id` (data, not schema). Multi-project mode is a config
-change (not a schema break). Tags run on the **v1.25.x** patch line:
-`v1.25.0` (P0) → `v1.25.5` (P5 = milestone release). Per `run.md`
-versioning logic: "Feature milestone (at least one feat phase):
-progressive patches per phase. The final phase's patch IS the milestone
-release. No separate minor tag."
-
-**Confidence:** 0.92. **Decision:** D-213.

-- D-211: Outcome backfill touches metrics cold store, NOT the PCR schema (v1.25 moat preserved).
+CAP-036 covers end-to-end verification.
-- D-212: Consumer repo has its own CI + unit tests; platform CI covers platform only.
+**Confidence:** 0.85. **Rationale:** Bundled wheels are the standard
-- D-213: Feature milestone; tags on v1.25.x (no schema breaks).
+workaround for Lambda native deps; the pure-Python fallback is a safe
+degradation. Fargate is the escape hatch if Lambda's runtime is
+fundamentally incompatible. RESEARCH will validate wheel availability for
+Python 3.12 + the Lambda execution environment.
+**Impact if wrong:** Auth Lambda migrates to Fargate, adding ~1 week to P2.
+
+### Q2 — PAT revocation propagation latency
+
+The 60-second SLO (NFR-4) depends on whether the token-vend Lambda reads
+PAT revocation state from DynamoDB on every request (eventually
+consistent reads) or via a cached/denylist mechanism.
+
+**Resolution (D-229):** Read-on-every-request with strongly consistent
+reads on the PAT hash table. Cost is acceptable given expected request
+volume (token vending is not a hot path — it precedes a deploy, not every
+request). REV-351 verifies the SLO in CI.
+**Confidence:** 0.90. **Rationale:** Strongly consistent DynamoDB reads
+have single-digit-ms latency at expected volume; the 60s SLO has >10x
+headroom. A cache layer adds invalidation complexity that the SLO does
+not require.
+**Impact if wrong:** If read latency exceeds 60s under load, introduce a
+DynamoDB TTL + cache layer; SLO must be re-verified.
+
+### Q3 — JWKS endpoint: Lambda function URL vs. API Gateway
+
+A function URL is simpler and cheaper but lacks throttling, WAF, and
+custom domains out of the box.
+
+**Resolution (D-230):** Start with a Lambda function URL behind a custom
+domain; rate limiting configured at the DNS/CDN layer. API Gateway
+migration deferred to v1.19+ if throttling requirements grow.
+**Confidence:** 0.80. **Rationale:** The JWKS endpoint is public-key
+only (no secrets); the threat surface is low. Function URL + CDN rate-
+limiting covers the v1.28 volume. API Gateway is over-engineering until
+traffic patterns are known.
+**Impact if wrong:** If throttling becomes a requirement, API Gateway
+migration adds ~3-5 days.
+
+### Q4 — Mode resolver precedence with invalid `NOVA_CLIENT_MODE` value
+
+What happens if the env var is set to something other than `agent` or
+`interactive` (e.g., `NOVA_CLIENT_MODE=auto`)?
+
+**Resolution (D-226):** Invalid env var values are ignored, falling
+through to credential type. A warning is logged. Behavior is documented
+in the `nova-cli` README. This is a sub-clause of the mode-resolution
+priority decision.
+**Confidence:** 0.90. **Rationale:** Ignoring + warning is the least
+surprising behavior for an operator debugging mode issues. Failing hard
+would block legitimate workflows that set a stale/typo'd env var.
+**Impact if wrong:** Operators debugging mode issues may be confused;
+non-blocking.
+
+### Q5 — Service-account PAT vs. developer PAT in the same session
+
+What if both credential types are available (e.g., a developer explicitly
+exports a service-account PAT)?
+
+**Resolution (D-226):** The most recently acquired credential wins.
+Documented in `nova auth login` output. The credential type is what
+drives mode resolution (INV-14), so the operator sees which mode was
+selected and why.
+**Confidence:** 0.85. **Rationale:** "Most recent wins" is the simplest
+deterministic rule that matches operator mental models of "I just logged
+in as X." The audit event records the winning credential type, so the
+selection is traceable.
+**Impact if wrong:** Mode selection may surprise the operator; non-
+blocking, but `nova auth status` must make the active credential explicit.
+
+### Q6 — ABAC policy ownership and versioning
+
+`platform/abac/token-vend.policy` is referenced, but who owns changes?
+How are policy versions tracked in audit?
+
+**Resolution (D-231):** Policy changes require PR review; the policy
+version (git SHA) is recorded in every token-vend audit event. Owner:
+Platform Security. The policy file lives in the platform repo at
+`platform/abac/token-vend.policy` and is reviewed like any other
+production config.
+**Confidence:** 0.90. **Rationale:** Git SHA is the natural version
+identifier for a repo-resident policy; recording it in the audit event
+makes every allow/deny decision reconstructable to the exact policy text.
+**Impact if wrong:** Untracked policy changes could lead to unexpected
+allow/deny decisions in production, undermining audit defensibility.
+
+---
+
+## Grounding gaps surfaced in pre-flight (auto-resolved)
+
+### G1 — The `kj` engine does not exist; the spec treats it as locked.
+
+**Resolution (D-227):** The token-vend Lambda uses the existing
+**kyverno-json** engine (INV-4 swappable) as the ABAC evaluator. The
+policy at `platform/abac/token-vend.policy` is a kyverno-json policy.
+No new `kj` engine is built in v1.28. If a distinct `kj` engine is
+desired later, it is a separate research spike (not this milestone).
+**Confidence:** 0.95. **Rationale:** The repo already has a swappable
+policy engine (INV-4) implemented as kyverno-json. Building a second
+engine to do the same job violates the swappable-engine invariant's
+spirit. kyverno-json's `evaluate` semantics cover the spec's ABAC needs
+(subject, claims, resource, environment → allow/deny).
+**Impact if wrong:** If the user actually wants a new `kj` engine, v1.28
+scope expands significantly (engine design + implementation + migration).
+This was flagged as caveat #3 in the approved plan; the recommended path
+(kyverno-json) is locked here.
+
+### G2 — The spec's INV-18..21, INV-34, INV-63/64/65 don't exist.
+
+**Resolution:** Re-allocated as **INV-12..INV-17** (see REQUIREMENTS.md
+§v1.28 Invariants). The 1:1 mapping:
+- INV-63 (mode observability) → INV-12
+- INV-64 (mode determinism) → INV-13
+- INV-65 (credential type encodes role) → INV-14
+- INV-18..21 (attestation invariants) → INV-15 (no AWS-managed identity),
+  INV-16 (password storage), INV-17 (ABAC discipline). The spec's
+  attestation invariants INV-18..21 are partially covered by existing
+  invariants (INV-6 immutable audit) + INV-17; the JWS-from-PAT behavior
+  (REQ-332) is a requirement, not a separate invariant, in this mapping.
+- INV-34 (MFA enforcement) → deferred to v1.21+ (out of scope per §2.2);
+  no INV allocated in v1.28.
+**Confidence:** 0.85. **Rationale:** The mapping preserves the spec's
+intent without colliding with the repo's INV-1..11. INV-34 (MFA) is
+explicitly deferred per the spec's own §2.2 out-of-scope table.
+**Impact if wrong:** If the user wants the exact INV-18..21 semantics as
+separate invariants, INV-12..17 can be re-numbered; non-blocking.
+
+### G3 — The spec's CAP-025..030 collide with blockchain/pilot CAPs.
+
+**Resolution:** Re-allocated as **CAP-033..CAP-038** (see REQUIREMENTS.md
+§v1.28 + REQ-352). The 1:1 mapping:
+- CAP-025 (CLI subcommand surface) → CAP-033
+- CAP-026 (subcommand delegates to core/) → CAP-034
+- CAP-027 (layer matches wheel) → CAP-035
+- CAP-028 (Nova-idp auth flow) → CAP-036
+- CAP-029 (token-vend signs via KMS) → CAP-037
+- CAP-030 (PAT issuance + revocation) → CAP-038
+**Confidence:** 1.0. **Rationale:** Existing CAP-025..032 are
+blockchain/pilot capabilities (STATE.md); re-use would corrupt the
+capability registry. The re-allocated IDs are the next available.
+**Impact if wrong:** None — this is a numbering decision, not a semantic
+one.
+
+### G4 — The spec's REQ-001..031 collide / don't exist.
+
+**Resolution:** Re-allocated as **REQ-323..REQ-353** (1:1 with the spec's
+REQ-001..031). Full text in REQUIREMENTS.md §v1.28. Max existing REQ =
+REQ-322.
+**Confidence:** 1.0. **Rationale:** Same as G3 — avoid collision, use
+next available range.
+
+### G5 — `platform/abac/`, `nova/` subcommand dir, `nova-idp-*` Lambdas don't exist.
+
+**Resolution:** These are **greenfield deliverables** of v1.28 execution
+phases, not pre-existing "locked architectures." RESEARCH will design
+them; PLAN will sequence them; EXECUTE will build them. The spec's
+"Operating Principle 1" (incremental delivery) is honored — v1.28 is
+net-new work.
+**Confidence:** 1.0. **Rationale:** The spec itself describes these as
+new ("introducing Nova-idp"). The mis-framing was in calling them
+"locked" — they are locked in *scope*, not in *prior existence*.
+**Impact if wrong:** None — this is a framing correction.

+
+## Assumptions logged (full autonomy, no human escalation)
+
+1. **CodeArtifact is provisionable** in AWS account `581513795199` (the
+   pilot account). RESEARCH will confirm IAM permissions + repository
+   creation. If not, v1.28 falls back to a private PyPI server or a
+   Gitea-hosted wheel index; the CLI subcommand surface (REQ-324) and
+   identity layer (REQ-333+) are unaffected.
+2. **Python 3.12** is the target runtime for both the CLI wheel and the
+   Lambda functions (spec §4 REQ-004.3). The repo's current Python
+   version will be confirmed in RESEARCH; if it differs, the CLI pins
+   3.12 and Lambda uses the 3.12 runtime regardless.
+3. **KMS asymmetric signing** (RSA-2048 or ECDSA P-256) is available in
+   the target account. RESEARCH will confirm. If only symmetric KMS is
+   available, the token-vend Lambda uses symmetric signing + a public-key
+   publication step (less ideal, but functional); INV-15 is unaffected.
+4. **The Forge action** (REQ-326) is the existing `nova cli-action`
+   pattern, extended to both GitHub and Gitea marketplaces. The repo's
+   current Forge/Gitea workflow conventions (`.gitea/workflows/`,
+   `deploy.yml@v1.25`) are the baseline.
+5. **MFA/TOTP** code path ships in v1.28 (per spec §2.2) but enforcement
+   for prod/dr is deferred to v1.21+. This is a doc/test-only path in
+   v1.28 — no enforcement gate.

-PLAN.md. No work is blocked.
 
 ---
 
-## Challenges
+## Overall verdict: **PROCEED-WITH-CONDITIONS** · Confidence 0.76
 
-### G-Q1 — Is a homegrown PoA blockchain viable for a pilot, or is it reckless?
+The plan is fundamentally sound — architecture correct, re-mapping
+clean (no ID collisions), technical depth accurate (DER→raw, strong-
+read revocation, stdin TTY), highest-risk item (kj binary) has a
+Fargate fallback. Not unfeasible, not over-scoped beyond an agent-driven
+repo's capacity, not security-broken by design.
 
-**Challenge:** Authoring a blockchain (even a minimal PoA ledger) is a
+**3 critical conditions (must-fix before P1) + 16 tracked conditions.**
-non-trivial domain. A homegrown chain could have correctness bugs (hash
+No escalations (all axes ≥ 0.70 confidence).
-chain breaks, non-deterministic blocks, settlement-finality race
-conditions). Why not use a proven chain (Ethereum L2, Solana, Hyperledger
-Fabric)?
-
-**Verdict:** PROCEED (confidence 0.88). The pilot's purpose is to
-exercise the Nova platform's deploy/policy/attestation gates over a
-real consumer estate — not to build a production blockchain. A
-homegrown PoA ledger is the minimal viable chain: append-only blocks,
-single validator, SHA-256 hash chain, deterministic block production.
-This is ~200 lines of Python (block + ledger + validator). The chain
-needs to be real enough to record transactions + produce a settlement-
-finality signal for the kyverno-json policy (REQ-315) — not to solve
-Byzantine consensus. A proven chain (Ethereum/Solana/Hyperledger) would
-be the *consumer app's* choice, not the platform's; the platform is
-chain-agnostic. For the pilot, the homegrown chain avoids a heavyweight
-external dependency (a full node, smart contracts, gas models) that
-would obscure the platform-gates demonstration. REQ-310 tests cover
-chain integrity, hash determinism, genesis, append/verify — the
-correctness surface is bounded. Multi-validator BFT is a future
-milestone (D-201). No revision needed.
-
-### G-Q2 — Does "all types of securities" scope-explode the milestone?
-
-**Challenge:** The user said "offering all types of securities." Equities
-(D-200, pilot scope) is one type. Bonds (T+2), derivatives (varying),
-options (exercise models) have very different settlement models. Does
-the equities-only deferral betray the user's intent?
-
-**Verdict:** PROCEED (confidence 0.85). The user *chose* equities-only
-pilot (Q4 in the plan discussion, answer "A to all 3 questions" — the
-recommended scope). "All types of securities" is the *product vision*;
-v1.26 is the *pilot* (equities first). The roadmap documents the
-deferral. The pilot demonstrates the Nova platform's gates over the
-simplest settlement model (T+1); expanding to other security types is
-a straightforward extension (new settlement-service branches + new
-kyverno-json policies) once the platform-gates pattern is proven. No
-revision needed — the scope decision is the user's, not the grill's.
-
-### G-Q3 — Does the consumer-repo-as-2nd-project break single-project tooling?
-
-**Challenge:** CIAgent has been single-project since v1.0. v1.26
-activates multi-project mode (2 projects: `acdl` +
-`nova-blockchain-exchange`). Does this break assumptions in the
-CIAgent tooling (branch naming, `.ciagent/` paths, commit `---ci---`
-blocks)?
-
-**Verdict:** PROCEED (confidence 0.90). `run.md` Step 0 explicitly
-specifies multi-project mode: `projects[]` with length > 0,
-`active_projects` array, `.ciagent/<slug>/` subdirectory paths, branch
-prefixes `<slug>/`. The `---ci---` block gains a `project: <slug>`
-field (already in the v1.26 commits). The consumer's project files
-live in `.ciagent/nova-blockchain-exchange/`. The platform's existing
-flat `.ciagent/` files remain the primary set (the platform is the
-default project). Branch naming: the consumer's phases use
-`nova-blockchain-exchange/phase/01-...`; the platform's phases use
-`acdl/phase/03-...` (or flat `phase/03-...` for platform-level work).
-No tooling change needed — the multi-project spec is already in
-`run.md`. D-206 records this. No revision needed.
-
-### G-Q4 — Does the P2 contract reference a `dynamodb` module that doesn't exist until P3?
-
-**Challenge:** The original plan had REQ-322 (DynamoDB primitive) in
-P3, but the P2 contract (REQ-313) references `dynamodb` in its
-`infrastructure` block. If the primitive doesn't exist until P3, the
-P2 contract's `dynamodb` block can't resolve at registry time — only
-at schema time (the schema is open). Is this a vertical-slice
-violation (P2 ships a contract that can't fully resolve)?
-
-**Verdict:** REVISE (confidence 0.92). This is a real vertical-slice
-violation. PLAN.md already revised: REQ-322 moves to P2 W0 (before the
-contract). The revised mapping (PLAN.md "Revised: REQ-322 → P2 W0")
-makes P2 self-contained: the primitive + the contract + the deploy
-invocation all land in P2. This is a binding revision — the original
-P3 placement is superseded. ROADMAP.md is already updated (REQ-322 in
-P2). No further revision needed — the plan self-corrected.
-
-### G-Q5 — Does live-AWS pilot break the MTTR < 60s target?
-
-**Challenge:** NORTH_STAR.md MTTR target: < 60s p95. The pilot runs
-`terraform apply` (creating real AWS resources: ECS + DynamoDB + S3).
-Apply latency for a 3-resource stack is typically 2-5 minutes (ECS
-service creation is the slow step). Does this break the MTTR target?
-
-**Verdict:** PROCEED (confidence 0.86). The MTTR target is for
-*platform-detected + platform-remediated incidents* (apply.failed →
-successful retry), not for first-time apply latency. The pilot's
-first apply is a deployment, not an incident-remediation. The MTTR
-metric measures the retry path: if the apply fails (e.g. IAM
-permission), the platform retries — the retry MTTR is the time from
-`apply.failed` to `apply.succeeded`, which is < 60s for a retry (the
-resources are already partially created; the retry completes the
-remaining steps). The pilot's apply latency is a deployment metric
-(lead time), not an MTTR metric. RESEARCH §1.2 (v1.25 grill G-Q3)
-analyzed this same question for the kyverno-json pass — the same
-reasoning applies. No revision needed.
-
-### G-Q6 — Is the settlement-finality policy (REQ-315) over-engineering for a pilot?
-
-**Challenge:** A kyverno-json policy asserting settlement finality
-(`all_committed: true`) before promotion is a securities-specific
-extension of v1.25's policy engine. Is this over-engineering for a
-pilot that only runs in `dev` (autonomous, no promotion to qa/prod/dr
-in v1.26 per D-208)?
-
-**Verdict:** PROCEED (confidence 0.80). The policy is *authored* in
-v1.26 (P3) but its *enforcement* activates when a promotion to qa/prod
-happens — which is a *future* milestone (D-208: qa/prod/dr stay
-placeholder this milestone). The policy is tested (passing + failing
-fixtures; skip when `kj` absent) in P3, but it doesn't gate a `dev`
-apply (the pilot-readiness policy REQ-320 gates `dev`; the settlement-
-finality policy gates promotions). Authoring + testing the policy in
-v1.26 is the right thing: it (a) proves the kyverno-json engine can
-assert a domain invariant, (b) ships the policy artifact so a future
-milestone that binds qa/prod/dr can enable it without re-architecting,
-(c) extends v1.25's moat (the policy engine is swappable + extensible
-to new domains). The cost is ~1 policy file + 1 test file. No revision
-needed — but the POLICY IS NOT ENFORCED in v1.26 (it's authored +
-tested, enforcement is future). PLAN.md should note this. **Minor
-revision: PLAN.md P3 W4 Task 4.1 should note "policy authored + tested;
-enforcement deferred to the milestone that binds qa/prod/dr."** Already
-implicit in the plan (the policy gates promotions, not dev applies);
-making it explicit is a documentation refinement, not a scope change.
-
-### G-Q7 — Is D-083 deferral defensible for a pilot with real money-like flows?
-
-**Challenge:** The pilot is a stock exchange — securities trading. D-083
-(S3 Object Lock / JWS tamper-evident ledger) is deferred (D-204). The
-SQLite hash-chain + DynamoDB outbox is the audit record. Is this
-defensible for a domain where audit integrity is legally mandated?
-
-**Verdict:** PROCEED (confidence 0.82). The pilot is a *technical
-demonstration*, not a production trading system. No real money, no real
-securities, no real investors — the "securities" are test tokens on a
-homegrown chain. The audit integrity requirement (SEC Rule 17a-4, FINRA
-retention) applies to *production* trading systems, not to a pilot
-exercising a platform's deploy/policy/attestation gates. The SQLite
-hash-chain + DynamoDB outbox is a tamper-*evident* record (any tampering
-breaks the hash chain) — it's just not tamper-*resistant* (S3 Object
-Lock + JWS would make it tamper-resistant). For a pilot, tamper-evident
-suffices. D-083 lift is a future milestone (when the pilot becomes a
-production system). D-204 records this. No revision needed.
-
-### G-Q8 — Does the outcome-backfill emitter (REQ-317) touch the PCR schema?
-
-**Challenge:** REQ-317 wires `apply.completed`/`apply.failed` →
-`fact_decision.outcome`. The v1.25 hard constraint says "DO NOT change
-`schemas/policy_check_result.schema.json`." Does the backfill touch the
-PCR schema?
-
-**Verdict:** PROCEED (confidence 0.95). D-211 (CLARIFY) already
-resolved this: the outcome backfill touches the *metrics cold store*
-(`fact_decision` table in `metrics/nova_metrics.db`), not the PCR
-schema. The backfill reads run-manifest events (not PCRs) and updates
-the decision's outcome column. The PCR schema is unchanged. This
-respects the v1.25 hard constraint. No revision needed.
-
-### G-Q9 — Does the `NOVA_AWS_*` root-equivalent key create a security risk?
-
-**Challenge:** D-207 says `NOVA_AWS_*` has root-equivalent permissions
-(confirmed empirically: the bootstrap created the S3 bucket + DynamoDB
-table). Using a root key for the pilot's `terraform apply` is a
-security risk — a key compromise gives full account access. Should the
-pilot use a least-privilege key?
-
-**Verdict:** PROCEED (confidence 0.78). The risk is real but bounded:
-(a) the pilot runs in a single account (`581513795199`) with no
-production workloads (the v1.11 teardown left it empty; the pilot is
-the only workload), (b) the key is in `.env.secrets` (gitignored, never
-committed), (c) the deploy workflow uses OIDC by default (the static
-key is the override, not the primary path). A future hardening
-milestone should split `NOVA_AWS_*` into a root `NOVA_BOOTSTRAP_AWS_*`
-+ a least-privilege `NOVA_AWS_*` runner key (the spike-runner pattern).
-For v1.26, the single key suffices (pilot scope). D-207 records this.
-**Minor revision: PLAN.md should note the key-split as a future
-hardening item.** Already implicit in D-207; making it explicit in the
-plan is a documentation refinement.

+4. `nova apply --local` produces a JWS attestation verifiable with the
+   public key derived from the PAT (REQ-332).
+5. `nova idp setup --check` reports prerequisites + IAM policy delta;
+   `--apply` presents the CloudFormation template for review before any
+   resource is created (NFR-10); `--verify` confirms the KMS round-trip.
+6. The Forge action (`nova cli-action`) runs `nova apply` in
+   `mode=agent, selection_reason=credential:service_account_pat` with
+   no TTY dependency (Journey 3, INV-12).
+7. PAT revocation takes effect within 60s P95 (NFR-4, CAP-038).

-## Wave Ordering Rationale
+## Capability gate (CAP-033..CAP-038)
 
-- **P1 W1 → W2:** the chain core (block + ledger + validator) must land
+| CAP | Name | Phase | Gate rule |
-  before the order engine + settlement (they submit transactions to the
+|-----|------|-------|-----------|
-  ledger). W3 (CI) is cross-cutting + can land any time after W1.
+| CAP-033 | CLI subcommand surface exists | P1 | `nova --help` lists a subcommand for every `core/` module |
-- **P2 W1 → W2:** the contract must land before the deploy invocation
+| CAP-034 | Subcommand delegates to `core/` | P1 | Every `nova/<module>.py` ≤50 lines, no business logic, AST scan |
-  (the invocation references the contract). W3 (floating tag) is cross-
+| CAP-035 | Layer matches wheel | P1 | Lambda layer ARN version matches `nova-cli` wheel version (SSM mapping) |
-  cutting.
+| CAP-036 | Nova-idp auth flow works | P3 | E2E test (sign-up → sign-in → session) passes in CI |
-- **P3 W1 (DynamoDB) first:** the contract (P2) references `dynamodb` —
+| CAP-037 | Token-vend signs via KMS | P4 | KMS round-trip test (REQ-350) passes in CI |
-  the primitive must exist before P2's contract can resolve. **Risk:**
+| CAP-038 | PAT issuance + revocation | P4 | Issue → vend → revoke → 403 within 60s P95 (REQ-351) passes in CI |
-  P2's contract references a module that doesn't exist until P3. Resolution: P2's contract is authored but the `test_contract_validates.py` test only checks schema validity (not registry resolution) — the registry resolution test is in P3 (after the primitive lands). The contract's `dynamodb` block is schema-valid (the schema is open); the registry resolution happens at apply time (P4).
+**Release gate (§6 of the spec):** CAP-001..CAP-032 remain Verified;
-  - **Alternative:** move REQ-322 to P2 W0 (before the contract). This
+CAP-033..CAP-038 are Verified; all v1.28 release-gate criteria met.
-    avoids the P2→P3 dependency. **Decision: move REQ-322 to P2 W0.**
-    See revised mapping below.
-
-### Revised: REQ-322 → P2 W0
-
-REQ-322 (DynamoDB primitive) lands in P2 Wave 0 (before the contract)
-so the contract's `dynamodb` block resolves at registry time, not just
-schema time. This makes P2 self-contained: the primitive + the contract
-+ the deploy invocation all land in P2.

+## Cost envelope (C-3.1)
+
+Monthly estimate for the default (no CloudFront) Nova-idp deployment in
+account `581513795199`:
+
+| Resource | Quantity | Pricing | Est. monthly |
+|----------|----------|---------|-------------|
+| DynamoDB (on-demand) | 4 tables | $1.25/1M write, $0.25/1M read | ~$1 (pilot volume) |
+| DynamoDB PITR | 4 tables | $0.20/GB-month | ~$1 (small tables) |
+| KMS asymmetric key | 1 key | $1/key-month + $0.03/10k signs | ~$1 |
+| Lambda invocations | 3 Lambdas | $0.20/1M req + $0.000016/GB-s | ~$2 (low volume) |
+| Lambda layer storage | ~50 MB | $0.02/GB-month | <$1 |
+| CodeArtifact | 1 domain + 1 repo | $1/domain + $1/repo | $2 |
+| SSM Parameter | 1 | $0.05/param (advanced) | <$1 |
+| **Total (default)** | | | **~$9/month** |
+
+Optional CloudFront + WAF + ACM (if `--public-jwks-domain`): +~$3/month
+at pilot volume. ACM is free for CloudFront-attached certs.
+
+This is a pilot-scale cost envelope. Production scale (100x volume)
+would still be <$50/month. No hidden costs identified.

+
+### v1.28 ID allocations (re-mapped — no collisions with shipped history)
+
+- **Decisions:** `D-226..D-231` (authored in CLARIFY). Repo decision
+  namespace is `D-NNN` (max D-225); no `D-NEW-*` namespace exists.
+- **Requirements:** `REQ-323..REQ-353` (31 REQs, mapping the spec's
+  REQ-001..REQ-031 1:1). Max existing REQ = REQ-322.
+- **Capabilities:** `CAP-033..CAP-038` (mapping the spec's CAP-025..CAP-030).
+  Existing CAP-025..032 are blockchain/pilot — collision avoided.
+- **Invariants:** `INV-12..INV-17` (mapping the spec's INV-63,64,65,18..21,34).
+  Max existing INV = INV-11.
+- **`kj` engine → kyverno-json.** The spec references a `kj` engine; the
+  repo's actual policy engine is `kyverno-json` (INV-4 swappable). v1.28
+  uses kyverno-json as the ABAC evaluator for token-vend; no new `kj`
+  engine is built. This is a CLARIFY-grounded re-mapping, not a silent
+  assumption (D-229).
+
+### v1.28 Requirements
+
+New requirements REQ-323..REQ-353 — full text in
+`.ciagent/REQUIREMENTS.md` §v1.28. Summary by priority:
+
+- **P1 — CLI Substrate (REQ-323..REQ-328):** CodeArtifact wheel + Lambda
+  layer pipeline; CLI subcommand per `core/` module; `nova init`
+  scaffolding; `nova cli-action` published to GitHub + Gitea;
+  `mode_resolver.py` (flag → env → credential type → TTY); audit
+  emission with `mode` + `selection_reason`.
+- **P2 — Lambda Packaging + Identity Layer (REQ-329..REQ-344):** dual-use
+  `core/lambda/contract_ingestor.py`; local env synthesizer; JWS signing
+  key from PAT; `nova-idp-auth` Lambda (Argon2id, DynamoDB); DynamoDB
+  tables (`nova-users`, `nova-sessions`, `nova-password-resets`);
+  `nova-idp-token-vend` Lambda (KMS-signed OIDC, JWKS endpoint); kyverno-json
+  ABAC policy at `platform/abac/token-vend.policy`; `nova idp setup`
+  (`--check/--apply/--verify`); CloudFormation review; PAT issuance +
+  hashes in DynamoDB; `nova auth login/revoke/status`.
+- **P3 — Documentation (REQ-345..REQ-347):** operator guide for
+  `nova idp setup`; developer guide for `nova auth login`; identity-layer
+  threat model.
+- **P4 — Integration Testing (REQ-348..REQ-351):** E2E sign-up → sign-in →
+  token-vend → apply → audit; property tests for `mode_resolver`; KMS
+  round-trip test; PAT revocation SLO test (≤60s P95).
+- **P5 — Capability Gate (REQ-352..REQ-353):** CAP-033..038 verification
+  gates wired into CI.
+
+### v1.28 Hard constraints
+
+- DO NOT depend on Cognito, IAM Identity Center, or any AWS-managed
+  identity service for sign-up/sign-in/token-vending (NFR-5). Nova-idp
+  signs OIDC tokens directly via KMS. (Note: no Cognito exists in the
+  repo today — this is a greenfield build, not a "Cognito drop".)
+- DO NOT build a new `kj` engine — use kyverno-json (INV-4).
+- DO NOT enforce MFA/TOTP for prod/dr this milestone — ship the code path,
+  enforce in v1.21+ (deferred, INV scope).
+- DO NOT add WebAuthn/FIDO2, upstream IdP federation, or password breach
+  detection — deferred to v1.23+.
+- DO NOT add Lambda layer auto-update on `core/` changes — v1.18 ships
+  manual `nova layer update`; v1.19 adds CI-triggered auto-update.
+- The token-vend Lambda MUST evaluate the kyverno-json ABAC policy before
+  signing; allow/deny decisions MUST be emitted to the audit stream
+  (NFR-9, D-227).
+- `nova idp setup --apply` MUST present the CloudFormation template for
+  review before any resource is created (NFR-10).
+
+### v1.28 phase status (active — phase 0 in progress)
+
+- **P0** pre-execution (SPECIFY→CLARIFY→RESEARCH→PLAN→GRILL→MVP/UX) — in
+  progress, target tag `v1.27.0`.
+- **P1..PN** execution phases — planned in PLAN.md.
+- **P(N+1)** final review + audit + milestone ship — target tag
+  `v1.27.(N+1)` = the v1.28 release.

+
+### Decisions (locked in CLARIFY — full autonomy, load-bearing for v1.28)
+
+- **D-226 (Mode resolution priority):** flag → env (`NOVA_CLIENT_MODE`) →
+  credential type → TTY heuristic. Invalid env values are ignored + warned,
+  falling through to credential type. No silent fallbacks (NFR-1).
+- **D-227 (ABAC engine = kyverno-json):** the token-vend Lambda uses the
+  existing kyverno-json engine (INV-4 swappable) as the ABAC evaluator,
+  not a new `kj` engine. Policy at `platform/abac/token-vend.policy`.
+- **D-228 (Argon2id in Lambda):** `argon2-cffi` with bundled wheels; if
+  the C extension fails to load, fall back to the pure-Python
+  implementation; if both fail, document the Fargate migration path.
+- **D-229 (PAT revocation SLO):** strongly-consistent DynamoDB read on
+  every token-vend request; revocation takes effect within 60s P95 (NFR-4).
+- **D-230 (JWKS endpoint):** Lambda function URL behind a custom domain;
+  rate limiting at the DNS/CDN layer. API Gateway migration deferred to
+  v1.19+ if throttling requirements grow.
+- **D-231 (ABAC policy ownership + versioning):** Platform Security owns
+  `platform/abac/token-vend.policy`; changes require PR review; the
+  policy version (git SHA) is recorded in every token-vend audit event.
+
+### P1 — CLI Substrate
+
+#### REQ-323 — CodeArtifact wheel + Lambda layer pipeline
+**Journeys:** J3. **Priority:** High.
+**AC:** Given a merge to `main` affecting `core/`, when CI runs, then both
+the wheel and the Lambda layer are published to CodeArtifact with
+identical version strings; if either fails, the merge is rejected.
+
+#### REQ-324 — CLI subcommand per `core/` module
+**Journeys:** J3. **Priority:** High.
+**AC:** (1) Every module in `core/` has a corresponding `nova/<module>.py`
+subcommand. (2) Subcommand files are ≤ 50 lines and contain no business
+logic — they delegate to `core/`. (3) CAP-034 verifies delegation by AST
+scan.
+
+#### REQ-325 — `nova init` scaffolds project
+**Journeys:** J2. **Priority:** High.
+**AC:** Given a directory with no `.nova/`, when Dev runs `nova init`,
+then `.nova/`, `.nova/contract.yml.attestations/`, and `.gitignore`
+(excluding secrets) are created.
+
+#### REQ-326 — `nova cli-action` published
+**Journeys:** J3. **Priority:** High.
+**AC:** (1) Action is available on both GitHub and Gitea marketplaces.
+(2) Integration test verifies byte-identical behavior on both platforms.
+(3) Python 3.12 is pinned.
+
+#### REQ-327 — `mode_resolver.py` priority
+**Journeys:** J2, J3. **Priority:** High.
+**AC:** (1) Explicit `--mode=agent|interactive` flag always wins.
+(2) Otherwise `NOVA_CLIENT_MODE` env var. (3) Otherwise credential type
+default. (4) Otherwise TTY heuristic. (5) Property tests cover all four
+levels. (6) INV-13 (mode determinism) enforced at PR time.
+
+#### REQ-328 — Audit emission with mode + selection_reason
+**Journeys:** J3. **Priority:** High.
+**AC:** Given any CLI invocation, when the CLI runs, then the emitted
+`cli.invocation` audit event contains `mode`, `selection_reason`,
+`credential_type`, `command`, and `args`. INV-12 (mode observability)
+enforced.
+
+### P2 — Lambda Packaging + Identity Layer
+
+#### REQ-329 — Dual-use Lambda/CLI import
+**Journeys:** J2. **Priority:** High.
+**AC:** Given `core/lambda/contract_ingestor.py`, when imported from the
+Lambda handler, then it executes the Lambda path; when imported from the
+CLI, then it executes the local path; and the two paths share ≥ 80% of
+their code.
+
+#### REQ-330 — Local env synthesizer
+**Journeys:** J2. **Priority:** High.
+**AC:** Given a contract and a `--local` flag, when `nova apply --local`
+runs, then a local env is synthesized via `core/env.py:get_env()` without
+provisioning cloud resources.
+
+#### REQ-331 — Attestations directory scaffolded
+**Journeys:** J2. **Priority:** High.
+**AC:** Given `nova init` ran, when Dev lists
+`.nova/contract.yml.attestations/`, then the directory exists and is empty.
+
+#### REQ-332 — JWS signing key from PAT
+**Journeys:** J2. **Priority:** High.
+**AC:** Given a PAT, when Dev runs `nova apply --local --sign-local-review`,
+then a JWS attestation is produced; the JWS is HMAC-SHA256 with a key
+derived from the PAT via `HKDF-SHA256(PAT_bytes, salt='nova-local-attestation',
+info='jws-signing-key')` → 32-byte symmetric key (C-5.2 grill fix). The
+verification key is derived from the PAT via the same KDF (the PAT is
+the shared secret). INV-14..17 (attestation invariants) enforced.
+
+#### REQ-333 — `nova-idp-auth` Lambda
+**Journeys:** J1, J2. **Priority:** High.
+**AC:** (1) Lambda exposes sign-up, sign-in, and session creation
+endpoints. (2) Passwords are hashed with Argon2id. (3) Sessions are
+stored in DynamoDB. (4) CAP-036 verifies end-to-end auth flow.
+
+#### REQ-334 — Argon2id password hashing
+**Journeys:** J1, J2. **Priority:** High.
+**AC:** Given a sign-up request, when the user record is persisted, then
+the password is stored as an Argon2id hash; raw passwords never appear in
+logs, traces, environment variables, or DynamoDB records.
+
+#### REQ-335 — DynamoDB tables for identity
+**Journeys:** J1. **Priority:** High.
+**AC:** (1) Tables exist: `nova-users`, `nova-sessions`,
+`nova-password-resets`. (2) Tables are provisioned by `nova idp setup`.
+(3) Point-in-time recovery is enabled on each.
+
+#### REQ-336 — `nova-idp-token-vend` Lambda
+**Journeys:** J1, J2, J4. **Priority:** High.
+**AC:** (1) Lambda accepts a PAT (or session token) and returns a
+KMS-signed OIDC token. (2) Token claims include `sub`, `aud`, `iss`,
+`exp`, and role claims. (3) ABAC policy is evaluated before signing.
+
+#### REQ-337 — KMS-signed OIDC tokens
+**Journeys:** J1, J4. **Priority:** High.
+**AC:** (1) Signing key is a KMS asymmetric key (RSA or ECDSA).
+(2) Token signature is verifiable via the JWKS endpoint. (3) KMS
+round-trip test passes. CAP-037 verifies.
+
+#### REQ-338 — JWKS endpoint as Lambda function URL
+**Journeys:** J1, J4. **Priority:** High.
+**AC:** Given the identity stack is deployed, when a client GETs the JWKS
+URL, then the public key(s) for token verification are returned with
+`Content-Type: application/json`.
+
+#### REQ-339 — kyverno-json ABAC policy file
+**Journeys:** J1, J4. **Priority:** High.
+**AC:** (1) Policy at `platform/abac/token-vend.policy`. (2) Policy inputs
+include subject, requested claims, target resource, and environment.
+(3) kyverno-json `evaluate` returns allow/deny; the decision is emitted to
+the audit stream.
+
+#### REQ-340 — `nova idp setup` walks admin
+**Journeys:** J1. **Priority:** High.
+**AC:** (1) Command supports `--check`, `--apply`, and `--verify` modes.
+(2) `--check` reports missing prerequisites and the required IAM policy.
+(3) `--apply` generates a CloudFormation template and requires explicit
+approval. (4) `--verify` runs the KMS round-trip test.
+
+#### REQ-341 — CloudFormation template for review
+**Journeys:** J1. **Priority:** High.
+**AC:** Given `nova idp setup --apply`, when the template is generated,
+then the template is presented for review; resources are not created until
+the operator approves; `--dry-run` shows the resource list without writing.
+
+#### REQ-342 — PAT issuance via portal
+**Journeys:** J4. **Priority:** High.
+**AC:** (1) PAT is a signed JWT. (2) PAT hash is stored in DynamoDB.
+(3) PAT includes a unique `jti` and an expiry claim. (4) Revocation marks
+the `jti` as revoked.
+
+#### REQ-343 — PAT hashes in DynamoDB
+**Journeys:** J4. **Priority:** High.
+**AC:** (1) Only the hash (not the raw PAT) is stored. (2) Table supports
+lookup-by-hash and lookup-by-`jti`. (3) Revoked PATs are retained for
+audit, not deleted.
+
+#### REQ-344 — `nova auth` commands
+**Journeys:** J2, J4. **Priority:** High.
+**AC:** (1) `nova auth login` exchanges session → OIDC token, stores
+locally. (2) `nova auth revoke --pat <id>` marks a PAT revoked.
+(3) `nova auth status` shows current credential, mode, and
+selection_reason. (4) All commands emit audit events.
+
+### P3 — Documentation
+
+#### REQ-345 — Operator guide for `nova idp setup`
+**Priority:** High.
+**AC:** Guide published covering `--check`, `--apply`, `--verify`,
+prerequisite IAM policy, and the CloudFormation review flow.
+
+#### REQ-346 — Developer guide for `nova auth login`
+**Priority:** High.
+**AC:** Guide published covering signup, signin, login, mode resolution,
+and credential-type behavior at a TTY vs. piped stdout.
+
+#### REQ-347 — Identity-layer threat model
+**Priority:** High.
+**AC:** Threat model published covering Argon2id storage, KMS signing,
+JWKS exposure, PAT revocation SLO, ABAC token vending, and the no-AWS-
+managed-identity constraint (NFR-5).
+
+### P4 — Integration Testing
+
+#### REQ-348 — E2E integration test
+**Priority:** High.
+**AC:** Given a deployed Nova-idp, when the test runs, then sign-up →
+sign-in → token-vend → apply → audit completes successfully; the audit
+event chain is verifiable.
+
+#### REQ-349 — Property tests for `mode_resolver`
+**Priority:** High.
+**AC:** (1) Property tests cover all four priority levels. (2) Edge cases:
+TTY but piped stdout, missing credential, conflicting flag/env, invalid
+env value. (3) INV-13 enforced via test.
+
+#### REQ-350 — KMS round-trip test
+**Priority:** High.
+**AC:** Given a token signed by the token-vend Lambda, when the test
+fetches the JWKS and verifies the signature, then verification succeeds.
+
+#### REQ-351 — PAT revocation SLO test
+**Priority:** High.
+**AC:** Issue PAT → use to vend token → revoke → assert denial within 60s
+P95. Test passes in CI.
+
+### P5 — Capability Gate
+
+#### REQ-352 — CAP-033..038 gate rules wired into CI
+**Priority:** High.
+**AC:** (1) CAP-033 (CLI subcommand surface exists): `nova --help` lists a
+subcommand for every `core/` module. (2) CAP-034 (subcommand delegates to
+`core/`): every `nova/<module>.py` ≤ 50 lines, no business logic, AST
+scan. (3) CAP-035 (layer matches wheel): Lambda layer ARN version matches
+the `nova-cli` wheel version. (4) CAP-036 (Nova-idp auth flow works): E2E
+test (REQ-348) passes. (5) CAP-037 (token-vend signs via KMS): KMS
+round-trip (REQ-350) passes. (6) CAP-038 (PAT issuance + revocation):
+REQ-351 passes. Failure of any → merge blocked.
+
+#### REQ-353 — Capability gate GREEN for v1.28 release
+**Priority:** High.
+**AC:** CAP-001..CAP-032 remain Verified; CAP-033..CAP-038 are Verified.
+All v1.28 release-gate criteria in PLAN.md §6 met.
+
+### v1.28 Invariants (new — INV-12..INV-17)
+
+- **INV-12 (Mode observability):** Every CLI invocation emits a
+  `cli.invocation` audit event containing `mode`, `selection_reason`,
+  `credential_type`, `command`, and `args`.
+- **INV-13 (Mode resolution determinism):** Resolution priority is
+  flag → env (`NOVA_CLIENT_MODE`) → credential type → TTY. No silent
+  fallbacks. Deviations rejected at PR time.
+- **INV-14 (Credential type encodes role):** `developer_pat` /
+  `nova_oidc_token` + TTY present → `interactive`; TTY absent → `agent`.
+- **INV-15 (No AWS-managed identity in path):** Nova-idp MUST NOT depend
+  on Cognito, IAM Identity Center, or any AWS-managed identity service.
+- **INV-16 (Password storage):** Passwords hashed with Argon2id; raw
+  passwords never in logs/traces/env/DynamoDB.
+- **INV-17 (ABAC discipline):** The token-vend Lambda evaluates the
+  kyverno-json ABAC policy before signing; allow/deny + policy inputs
+  emitted to the audit stream.

-## 1. Domain — Homegrown PoA Blockchain for Securities Settlement
+## §1 — Codebase Inventory (grounding)
 
-### 1.1 Why a homegrown chain (not Ethereum/Solana/Hyperledger)
+### 1.1 `core/` modules (the REQ-324 subcommand surface)
 
-The pilot's purpose is to exercise the Nova platform's deploy/policy/
+19 Python files under `core/` (plus `core/lambda/`, `core/metrics/`).
-attestation gates over a real consumer estate — not to build a
+Two already have `_cli.py` companions (`contract_resolver_cli.py` 40
-production blockchain. A homegrown PoA ledger is the minimal viable
+lines, `regression_verify_cli.py` 32 lines) — the thin-delegate
-chain: append-only blocks, single validator (pilot), SHA-256 hash chain,
+precedent for `nova/<module>.py`. **No `nova/` dir, no `bin/`, no
-deterministic block production. It records every order, match, and
+`[project.scripts]` entry exists today.** The CLI is greenfield.
-settlement as transactions; settlement finality = block commit. This
-is sufficient to demonstrate that Nova's policy engine (kyverno-json)
-can assert settlement finality declaratively (REQ-315) and that the
-Decision Ledger captures the apply decision.
 
-A production chain (Ethereum/Solana/Hyperledger) would be the *consumer
+### 1.2 Existing Lambda pattern (`core/lambda/contract_ingestor.py`)
-app's* choice, not the platform's. The platform is chain-agnostic — it
-deploys whatever the consumer's `contract.yaml` declares. For the pilot,
-the homegrown chain is the simplest way to produce a real consumer
-estate without a heavyweight external dependency.
 
-### 1.2 PoA consensus — single validator (pilot)
+521 lines. Function URL + IAM auth (D-051). DynamoDB via lazy
+module-global `boto3.resource`. Secrets Manager for tokens. Schema
+validation in-Lambda. **`__main__` block already does CLI dispatch**
+(`--check-readiness` → `core.submission_readiness.cli_main`) — this is
+the dual-use precedent for REQ-329. Local testing via
+`core/local_emulators.py:LocalLambdaStub`.
 
-Proof-of-Authority with a single validator is the minimal consensus
+### 1.3 `core/env.py` — getter, not synthesizer
-model: the validator proposes + commits blocks. No Byzantine fault
-tolerance (single validator = no forks). Deterministic block
-production: same ordered transactions → same block (same hash). This
-makes the chain auditable (the hash chain is verifiable) and
-reproducible (a replay produces the same chain). Multi-validator BFT
-is a future milestone (D-201).
 
-### 1.3 T+1 settlement finality
+31 lines. `get_env(name, default)` reads `NOVA_<name>` from `os.environ`.
+**REQ-330 needs a NEW `synthesize_local_env()` function** added here.
+The closest existing pattern is `core/onboarding.py:generate_env_file()`.
 
-Equities settle T+1 (trade date + 1 business day). The pilot's
+### 1.4 `PolicyEngine` Protocol + `KyvernoJsonEngine` (the ABAC substrate)
-settlement service records matches as transactions on the chain; a
-settlement is final when its block is committed. The settlement-finality
-kyverno-json policy (REQ-315) asserts `all_committed: true` before any
-promotion (qa→prod) — the declarative gate that turns settlement
-finality into a policy artifact. This is the securities-specific
-extension of v1.25's policy engine: the same `KyvernoJsonEngine`
-evaluates a policy over a new payload shape (settlement-service status
-JSON).
 
-### 1.4 Equities-only scope (D-200)
+`core/policy_engine.py`: `PolicyEngine` Protocol with `evaluate(payload,
+policy_dir, contract_id) -> list[dict]`. `KyvernoJsonEngine` shells to
+`kj scan --policy <dir> --payload <file> --output json`. Policy shape =
+`ValidatingPolicy` (`apiVersion: json.kyverno.io/v1alpha1`) with
+`spec.rules[].assert.all[].check` using JMESPath. Severity from
+`metadata.annotations["nova.cloudinit.dev/severity"]`. **The payload
+can be ANY JSON** — not just contracts (the v1.25 design point). This
+is what makes kyverno-json usable for ABAC token vending (D-227).
 
-Bonds (T+2), derivatives (varying), and options (exercise models) have
+### 1.5 `pyproject.toml` state
-different settlement models. A pilot should demonstrate the Nova
+
-platform's gates over the simplest case (equities T+1) before
+name `nova`, version `1.14.0`, requires-python `>=3.10` (spec wants
-expanding. "All types of securities" is the product vision; v1.26 is
+3.12 — bump needed for REQ-326). setuptools build backend. No
-the pilot (equities first). Future milestones add other security types
+`[project.scripts]`, no `[tool.setuptools.packages.find]` — both needed.
-with their settlement models.
+Deps: `boto3`, `jsonschema`, `pyyaml`. No `argon2-cffi`, `cryptography`,
+`pyjwt`, `click`/`typer` — **argparse-only** is the repo convention.
+
+### 1.6 Forge conventions
+
+`.github/workflows/` + `.gitea/workflows/` kept byte-identical. Python
+3.12 already pinned via `actions/setup-python@v5`. No composite action
+exists yet — `nova cli-action` (REQ-326) is greenfield.
+
+### 1.7 IAM baseline (load-bearing for REQ-340)
+
+`.ciagent/IAM_POLICY.md` + `terraform/bootstrap/spike_runner_policy.json`.
+The `nova-spike-runner` principal already has KMS (incl. `CreateKey`,
+`Sign`, `GetPublicKey`), Lambda (incl. `PublishLayerVersion`), DynamoDB
+grants. **New grants needed:** `cloudformation:*` (for `nova idp setup
+--apply`) + `codeartifact:*` (for the wheel publish pipeline). Flagged
+for P1/P2.
 
 ---
 
-## 2. Nova Consumer Deploy Model
+## §2 — CodeArtifact + Lambda Layer Pipeline (REQ-323)
 
-### 2.1 The reusable `deploy.yml@v1.25` workflow
+**Recommendation:** single CI job on merge to `main` affecting
+`core/**`/`adapters/**`/`nova/**`/`pyproject.toml`. Build wheel
+(`python -m build --wheel`) → `twine upload` to CodeArtifact → build
+layer (`pip install --target layer/python/ dist/nova-*.whl argon2-cffi
+cryptography pyjwt`) → `aws lambda publish-layer-version` → record
+version mapping in SSM `/nova/layer/nova-cli/version` (CAP-035). If
+either publish fails, the job fails (merge blocked, REQ-323 AC).
 
-The platform's `.github/workflows/deploy.yml` is a `workflow_call` —
+**Atomicity:** wheel publish is idempotent (pin version to
-a reusable workflow that a consumer repo invokes via
+`<semver>+<sha7>`); layer publish retries on failure. CAP-035 reads the
-`uses: acdl/.github/workflows/deploy.yml@v1.25`. Inputs: `contract`
+SSM parameter to verify layer-version ↔ wheel-version match.
-(default `.nova/contract.yml`), `mode` (default `full`; enum
-`full|plan-only|check-only|decommission`), `environment` (override).
-The workflow checks out the consumer repo + the platform repo, runs
-`scripts/run_platform.sh`, and records the apply decision +
-attestation in the Decision Ledger. Secrets: `NOVA_AWS_*`
-(account + access key + secret) + `NOVA_LAMBDA_URL` (error reporting).
 
-The pilot consumer (`nova-blockchain-exchange`) invokes this workflow
+**Risks:** CodeArtifact not yet provisioned in `581513795199` (CLARIFY
-with `mode: full` for `dev` (D-209). The `.gitea/workflows/deploy.yml`
+assumption #1); `codeartifact:*` grant missing. Fallback: Gitea-hosted
-mirror is byte-identical (the platform's deploy workflow is
+wheel index. Layer `--compatible-architectures`: build x86_64 only for
-forge-agnostic — Gitea + GitHub).
+v1.28 (aarch64 only if Graviton Lambda needed).
-
-### 2.2 `run_platform.sh --apply` path (confirmed)
-
-`scripts/run_platform.sh:431-455` — the `--apply` (or `mode: full`)
-path runs `terraform apply -auto-approve` after the HITL gate
-(`:438`). For `dev` (autonomous, no HITL gate), the apply proceeds
-directly. The apply records the env via `core/env_transition.py record`
-(`:450`). The full pipeline (no `--apply` flag) continues to Step 7
-(confidence signal) + Step 8 (outbox write).
-
-**Gap (noted in RESEARCH §4):** the `--apply` path exits before the
-outbox write (Step 8). The pilot runs the full pipeline (not `--apply`
-alone), so the outbox write happens. The `run.completed` event lands in
-the JSONL Decision Ledger (not the DynamoDB outbox) — this is by design
-(the outbox is the platform-run evidence stream; the Decision Ledger is
-the cold store for metrics).
-
-### 2.3 Contract schema — multi-module manifest
-
-`schemas/contract.schema.json:7,24-48` — required fields: `id`,
-`name`, `environment`, `infrastructure`. The `infrastructure` block is
-`minProperties: 1` with `patternProperties` accepting any module name
-key. Multi-module manifest is supported: one contract can declare
-`infrastructure: { microservice: {...}, dynamodb: {...}, s3: {...} }`.
-The constraint is the `modules/registry.json` (the module must be
-registered), not the schema.
 
 ---
 
-## 3. Platform Module Readiness (the critical finding)
+## §3 — CLI Subcommand Architecture (REQ-324)
 
-### 3.1 The adapter is stateless (v1.11 rewrite)
+**Recommendation:** three-layer. `nova/__init__.py` (marker) →
+`nova/cli.py` (~80 lines, auto-discovers `nova/<module>.py` via
+`pkgutil.iter_modules`, dispatches, emits `cli.invocation` audit event)
+→ `nova/<module>.py` (≤50 lines each, exports `add_parser(subparsers)`
++ `run(args) -> int`, delegates to `core/`). Entry point:
+`[project.scripts] nova = "nova.cli:main"`. **argparse-only** (no
+click/typer — repo convention).
 
-`adapters/terraform/adapter.py:1-11` — the adapter is a "STATELESS
+**CAP-034 AST scan:** ≤50 lines; ≤3 function defs; every `ast.Call`
-ASSEMBLER" that owns no module content. There is **no `TYPE_MAP`**,
+resolves to a `core.` import; no conditionals beyond `if __name__`.
-`INPUT_MAP`, or `OUTPUT_MAP` (deleted in the v1.11 stateless rewrite;
-`modules/STANDARDS.md:212-214` confirms). A new stack type requires a
-new L1 module (`modules/l1/<name>/` with `interface.json` +
-`terraform/main.tf` + `README.md` + `instance.json`) + a
-`modules/registry.json` entry — not an adapter change.
 
-### 3.2 ECS — ready
+**Subcommand groups:** `nova auth`, `nova idp`, `nova metrics` =
+nested subparsers (same pattern, one level deeper).
 
-`modules/l1/ecs-service/terraform/main.tf:1,11` —
+**setuptools:** add `[tool.setuptools.packages.find]` including `nova`,
-`aws_ecs_task_definition` + `aws_ecs_service`. `interface.json:5-6` —
+`nova.*`, `core`, `core.*`, `adapters.*`.
-`type: aws:ecs:task_definition`. `registry.json:29-37` — registered.
-Tests: `test_adapter.py:164-185,257-360`, `test_contract_resolver.py:61-92`.
-The `microservice` L2 (`modules/l2/microservice/composition.json`)
-references 6 L1 children (ecs-cluster, ecr, iam-role, alb, ecs-service,
-kms-key) — the ECS pattern is fully wired end-to-end.
-
-### 3.3 S3 — ready
-
-`modules/l1/s3/terraform/main.tf:1` — `aws_s3_bucket` (+ versioning +
-SSE). `interface.json:5-6` — `type: aws:s3:bucket`. `registry.json:2-10`
-— registered. Tests: `test_adapter.py:56-110,241-257`,
-`test_contract_resolver.py:36-51,92-130`.
-
-### 3.4 DynamoDB — GAP (REQ-322)
-
-**No `modules/l1/dynamodb/` directory, no `registry.json` key, no
-`interface.json`, no `terraform/`, no tests.** The blockchain exchange's
-ledger table needs this primitive. REQ-322 authors it: `interface.json`
-(stack type `aws:dynamodb:table`), `terraform/main.tf`
-(`aws_dynamodb_table` with PK + optional SK, `PAY_PER_REQUEST` default,
-encryption + PITR enabled per v1.8 NFR defaults), `README.md`,
-`instance.json`, + `registry.json` entry. The adapter needs no change
-(stateless); the contract's `infrastructure.dynamodb` block references
-this primitive. This is the single platform-side module build-out for
-the milestone.
-
-### 3.5 Stale doc (not a blocker)
-
-`adapters/README.md:49-54` references the deleted `TYPE_MAP`/
-`INPUT_MAP`/`OUTPUT_MAP` — contradicts `adapter.py:1-11` +
-`modules/STANDARDS.md:212-214`. REQ-321 (docs) should fix this.
 
 ---
 
-## 4. Metric Pipeline Grounding (Post-Pilot targets)
+## §4 — Argon2id in Lambda Python 3.12 (REQ-334, D-228)
 
-### 4.1 AI Decision Accuracy — outcome backfill (REQ-317)
+**Findings:** `argon2-cffi-bindings` v25.1.0 ships `cp39-abi3`
+manylinux x86_64 + aarch64 wheels — **ABI-stable, compatible with
+Python 3.9..3.13**. Lambda Python 3.12 runs Amazon Linux 2023 (glibc
+2.34 ≥ 2.28 required). **The abi3 manylinux wheel loads cleanly.**
+Confidence: 0.92.
 
-`core/metrics/decision_ledger.py:210-211` documents the event chain:
+**D-228 AMENDMENT:** the "pure-Python fallback" clause is **weaker than
-`confidence.computed → ai.decision.made → attestation.recorded →
+stated** — there is no maintained pure-Python Argon2 implementation. A
-run.completed/failed`. `collector.py:262` inserts `fact_decision.outcome`
+pure-Python crypto fallback is a **liability** (weaker hashing,
-as `"pending"` — **there is no outcome-backfill step** wiring
+violates INV-16's spirit). Revised recommendation:
-`run.completed`/`run.failed` back into `fact_decision.outcome`. The AI
+1. **Primary:** bundled manylinux abi3 wheel in the `nova-cli` Lambda
-Decision Accuracy metric (`trust_snapshot.py:70-85`, `_get_ai_decision_accuracy`)
+   layer. Works. Confidence 0.92.
-reads `decisions WHERE outcome='succeeded' ÷ total` — so it reads 0%
+2. **Fallback:** detect `ImportError` at Lambda cold-start → **fail
-today (all pending). REQ-317 adds `core/metrics/outcome_backfill.py`
+   closed** (503, refuse sign-ups). The Lambda health check reports
-that reads run-manifest events and updates `fact_decision.outcome` +
+   C-extension status. **Do NOT ship a pure-Python fallback.**
-`fact_decision.backfilled_at`. The PCR schema is unchanged (D-211).
+3. **Escape hatch:** Fargate (~1 week, per CLARIFY Q1).
 
-### 4.2 Human Escalation Frequency — `reason='confidence'` tag (REQ-318)
+Lambda memory ≥ 512 MB (Argon2id memory_cost ~20 MB + overhead).
-
-`core/confidence_signal.py:184` — a `block` band sets
-`human_override=True` in the `ai.decision.made` event.
-`run_platform.sh:636` fails the pipeline on `block`. The Human
-Escalation Frequency metric (`docs/metrics/human_escalation_frequency.md:11-12`)
-is defined as `count(runs WHERE hitl_block=1 AND reason='confidence') ÷
-total runs`. The `reason='confidence'` discriminator is **not currently
-stored** — `hitl_block` is a boolean from the manifest. REQ-318 adds
-`escalation_reason: 'confidence'` to the `ai.decision.made` event when
-`band == 'block'` + persists it into `fact_run` via the collector.
-
-### 4.3 Touchless Resolution Rate — denominator activates post-pilot
-
-`docs/metrics/touchless_resolution_rate.md:12-15` — defined as a SQL
-query over `fact_run` (`runs WHERE hitl_block=0 ÷ total runs`). The data
-lands in `fact_run.hitl_block` via `collector.py:216-227`. No dedicated
-emitter computes the ratio — it's a downstream query. The denominator
-is 0 today (no consumer runs). The pilot run activates the denominator.

-## 5. kyverno-json Policy Extensibility
+## §5 — KMS Asymmetric Signing for OIDC Tokens (REQ-337)
 
-`adapters/kyverno-json/kyverno_json_engine.py:74-80` — the engine is
+**Recommendation: key spec = `ECC_NIST_P256`, alg = `ECDSA_SHA_256`
-**policy-dir agnostic**: it loads whatever subdir the caller passes.
+(JWS `ES256`).** RSA-2048 is larger + slower; P-256 is RFC 7518's
-Existing subdirs: `contract/`, `stack-ir/`, `plan-json/`, `meta/`,
+recommended JWT alg. Signature size 64 bytes (vs RSA 256). JWKS
-`regression/`. Adding a new subdir (e.g. `pilot-readiness/`,
+compactness matters (fetched often).
-`settlement-finality/`) requires: (1) `mkdir
-adapters/kyverno-json/policies/<name>/`, (2) drop `ValidatingPolicy`
-YAML/JSON files, (3) wire a caller. No engine code change needed.
-Test pattern: one test file per subdir (`tests/test_<name>_policies.py`).
 
-The pilot adds two new policy subdirs: `pilot-readiness/`
+**The #1 gotcha:** KMS returns DER-encoded ECDSA signatures; **JWS

+decode_dss_signature` → `r.to_bytes(32) + s.to_bytes(32)`. ~5 lines.
+Flagged for the threat model (REQ-347) + KMS round-trip test (REQ-350).
+
+**Flow:** validate PAT → ABAC eval → build JWT header/payload →
+`kms.sign(Message=signing_input, MessageType="RAW", SigningAlgorithm=
+"ECDSA_SHA_256")` → DER→raw → JWT. `kid` = KMS key alias.
+
+**Verification:** use `pyjwt` (`jwt.decode` handles JWK→key natively);
+`cryptography` only for SPKI→JWK in the JWKS Lambda.
+
+**Rotation:** manual, 90 days (matches D-069 CMK cadence). New key +
+re-point alias + JWKS serves both `kid`s during overlap.

+(not raw PAT). Revoked PATs retained for audit.
+
+**Revocation (D-229 CLARIFIED):** GSIs don't support strongly-consistent

+without verifying — signature verified separately) →
+`GetItem(PK=jti, ConsistentRead=True)` on the main table. Satisfies the
+60s SLO. Confidence 0.90.
+
+**CLI:** `nova auth login` (session→OIDC token, store locally),
+`nova auth revoke --pat <jti>`, `nova auth status` (active credential,
+mode, selection_reason). Local file `~/.nova/credentials.json` (0600,
+never to stdout, in `.gitignore`). "Most recent wins" (D-226 Q5) =
+`active_credential_jti` field.
+
+---
+
+## §9 — `nova idp setup` CloudFormation (REQ-340, REQ-341)
+
+**Template (raw dict → JSON, no troposphere dep):** 2-3 Lambdas, 4
+DynamoDB tables (`nova-users`, `nova-sessions`, `nova-password-resets`,
+`nova-pats`), KMS key `alias/nova-oidc-signing` (ECC_NIST_P256),
+function URLs, IAM roles, optional CloudFront/WAF/ACM.
+
+**`--check`:** validates prerequisites (AWS creds, CFN perms, KMS perms,
+layer exists via CAP-035). Prints required IAM policy delta.
+**`--apply`:** generate → print to temp file + resource summary →
+`$PAGER` → `Apply? [y/N]` → `cloudformation deploy --capabilities
+CAPABILITY_IAM`. NFR-10 satisfied by the explicit prompt.
+**`--dry-run`:** resource list only, no write.
+**`--verify`:** runs the KMS round-trip test (REQ-350).
+
+**New IAM grants needed:** `cloudformation:*`, `iam:CreateRole`/`PassRole`,
+`lambda:CreateFunction`/`CreateFunctionUrlConfig`,
+`dynamodb:CreateTable`, `kms:CreateKey`/`CreateAlias`, `ssm:PutParameter`.

+**Byte-identical test (REQ-326 AC2):** CI matrix runs the action on
+GitHub `ubuntu-latest` + Gitea `act_runner` with same inputs; assert
+same stdout/exit code.

+mirrors (`https://gitea.com/actions/...`). P1 test on the actual Gitea
+instance. Confidence 0.70.

+## §11 — `mode_resolver` Priority (REQ-327, D-226)
+
+**TTY detection: check `sys.stdin.isatty()`** (NOT stdout). Edge 3
+(`nova apply | tee log.txt`): stdout piped, stdin is TTY → user is
+present → `interactive` (correct). `sys.stdout.isatty()` would
+misresolve to `agent`. **`stdin` answers "is a human at a terminal?"**
+
+**Credential type detection:** read `~/.nova/credentials.json` →
+`active_credential_jti`'s `type` (`developer_pat`/`nova_oidc_token`).
+Both + TTY → `interactive`; + no TTY → `agent` (INV-14).
+
+**Property tests (REQ-349):** `hypothesis` with strategies for
+flag/env/cred/tty. Properties: deterministic (INV-13), flag-wins,
+invalid-env-ignored, no-silent-fallback (every resolution has a
+non-empty `selection_reason`).
+

+
+## How to use this file (PO)
+
+- Before writing a new REQ: search this file for the capability you
+  intend to spec. If it exists, extend it; do not re-spec it under a new
+  REQ-NNN.
+- Respect the **Invariants** below — they are load-bearing and
+  cross-cutting. A new REQ that violates an invariant requires a
+  `CLARIFY` decision recorded in PROJECT.md.
+- Anchor each new REQ to a **Domain**; new domains require a PO
+  decision recorded in CLARIFY.
+- When a capability is deprecated (replaced, removed, or
+  re-architecture), append a `Deprecated` row marking the milestone +
+  replacement; do not delete the original entry.
+
+## Invariants (PO-owned — do not violate in new REQs)
+
+> Distilled from `PROJECT.md` load-bearing decisions D-034..D-072 +
+> W1..BA + Q1.3. Cite the decision ID when an REQ touches one.
+
+- **INV-1 (Contract surface):** The only PDLC→Nova boundary is
+  `schemas/contract.schema.json` + `schemas/submission-readiness.schema.json`
+  (D-133). All consumer intent enters through one of these. Nova never
+  reaches into upstream PDLC.
+- **INV-2 (Confidence inputs):** Six canonical inputs — policy (0.30),
+  validation (0.25), freshness (0.10), source (0.15), history (0.10),
+  nfrs (0.10). Weights frozen for v1 (D-040). `critical` severity =
+  hard-block via `PENALTY["critical"]: None` (defense-in-depth behind the
+  declarative `block-on-any-critical` meta-policy).
+- **INV-3 (HITL gates):** dev = autonomous (≥0.50); qa = HITL (≥0.75);
+  prod = HITL (≥0.90); dr = HITL (≥0.95). Approver identity = Gitea
+  `gitea.actor` of the `workflow_dispatch` (D-042). Separation-of-duties
+  on prod reads `approver_qa` from the DynamoDB outbox.
+- **INV-4 (Engine is swappable):** The policy engine is behind the
+  `PolicyEngine` protocol (`core/policy_engine.py`, v1.25). Confidence
+  signal + pipeline import only the protocol, never a concrete engine.
+  `kyverno-json` is the v1.25 default; `OPA` (or other) implements the
+  same 3-method protocol to replace it.
+- **INV-5 (Adapter is stateless):** `adapters/terraform/adapter.py` owns
+  no module content — no `TYPE_MAP`/`INPUT_MAP`/`OUTPUT_MAP` (v1.11
+  rewrite). A new stack type requires a new L1 module
+  (`modules/l1/<name>/`) + `registry.json` entry, not an adapter change.
+- **INV-6 (Audit stream is immutable):** Outbox writes via SQLite
+  hash-chain today (D-083 deferred). S3 Object Lock / JWS tamper-
+  *resistant* ledger is a future milestone. Current stream is tamper-
+  *evident* (any tampering breaks the chain).
+- **INV-7 (PCR schema is the moat):** `schemas/policy_check_result.schema.json`
+  shape is frozen across adapter swaps (v1.25 hard constraint). The
+  `engine` enum already includes `"kyverno"` + `"opa"`; new engines add
+  no enum value.
+- **INV-8 (Long-lived creds forbidden):** §12.5. The D-039/D-047 per-run-
+  rotated-key waiver satisfies the *intent* (no *persistently* long-lived
+  key). Real OIDC federation is blocked on `go-gitea/gitea#36988`.
+- **INV-9 (Two consumer surfaces, one platform):** L3A (developer) +
+  L3B (citizen dev) converge on the same contract schema, the same
+  policy envelope, and the same evidence stream.
+- **INV-10 (Nova is downstream of PDLC):** Nova governs infra + delivery
+  only. Product backlog, code authorship, IDE workflows, application
+  business logic are upstream. Integration only via the validated
+  contract boundary (INV-1).
+- **INV-11 (Pilot scope, v1.26):** Equities only (D-200). Single-
+  validator PoA (D-201). D-083 (Object Lock/JWS) stays deferred. Hot
+  path deferred (D-126). Multi-cloud deferred. Multi-validator BFT
+  deferred. The pilot runs `mode: full` for `dev` only (D-209); qa/prod/dr
+  stay placeholder (D-208, blocked by the pilot-readiness policy).

+## Update discipline
+
+This file is updated **once per milestone, at the P-final milestone-ship
+wave** (Wave 3 "milestone ship" in `PLAN.md`), alongside
+`ROADMAP.md`/`NORTH_STAR.md`/`REQUIREMENTS.md`:
+
+1. Append new capability entries for each shipped REQ (one row per
+   capability; group by domain).
+2. Mark any deprecated capability with a `Deprecated` row citing the
+   milestone + replacement.
+3. Bump the "Last milestone ship" header.
+4. Do not rewrite existing entries (additive only).
+
+Enforcement: convention (the P-final ship step names this file). A
+drift-check gate (assert every REQ marked `complete` in
+`REQUIREMENTS.md` traceability appears in STATE.md) is a future option
+if the convention drifts.

+
+Multi-persona review across P1..P4 (lead-developer coordination;
+correctness / testing / security / maintainability axes). The spot-checks
+below confirm the P3/P4 commits deliver what their messages claim.
+
+### Correctness spot-checks (all PASS)
+
+- **kyverno-json substrate fix (59d837f):** the engine `_translate` parses
+  the real `kj` v0.0.3 bare-list output (not the v1.25-assumed
+  `{"results":[...]}` dict); `_materialize_yaml_policy_dir` mirrors `.json`
+  policies to `.yaml` twins (kj v0.0.3 ignores `.json`); the `validate`
+  wrapper was removed from all 16 policies + the check syntax fixed
+  (`expression: expected_value`). All 36 kj-dependent tests pass against
+  real `kj` (0 skips). The install script fixed
+  (`go install .../kyverno-json@latest` + symlink, not the broken
+  `cmd/kj@latest`).
+- **outcome backfill (51b886f, REQ-317):** `core/metrics/outcome_backfill.py`
+  updates `fact_decision.outcome` pending → succeeded/failed; idempotent +
+  terminal (no overwrite of a non-pending outcome); wired into the
+  collector. The P4 run evidence (6ced8ed) confirms
+  `nova.outcome.backfilled (pending->succeeded)`.
+- **Gitea adapter (P3 W0):** the consumer `deploy.yml` has no cross-repo
+  `uses:` — inline `actions/checkout@v4` of `acdl/acdl @ ref: v1.25` into
+  `platform/` then `bash platform/scripts/run_platform.sh`. SPEC §10 Q1
+  resolved by evidence.
+- **env-JSON state_backend (3300ed2, REQ-319):** the adapter reads
+  `env.state_backend.bucket` when present (fallback to the computed
+  `nova-tfstate-{account_id}-{region}` for backwards compat). `dev.json`
+  bound to `581513795199` + `nova-tfstate-581513795199-us-east-1`;
+  qa/prod/dr stay placeholder (account `000000000000` — the pilot-readiness
+  policy blocks apply, D-208).
+- **pilot policies (e22661a, REQ-315/320):** `no-placeholder-account.json`
+  passes on dev (581513795199), fails on placeholder;
+  `all-matches-committed.json` asserts `all_committed == true`. Both run
+  against real `kj` (not skipped).
+
+### Testing
+
+- 844 tests collected; **844 pass** (839 fast + 5 slow individually
+  re-run: 2 `test_run_local_e2e_*` + 3 `test_verify_regression_mode::*`).
+  0 failures, 0 skips that shouldn't skip.
+- New feature coverage confirmed: REQ-317 backfill test
+  (`test_outcome_backfill.py`), REQ-318 escalation_reason test
+  (`test_confidence_escalation_reason.py`), REQ-315/320 policy tests
+  (`test_settlement_finality_policy.py`, `test_pilot_readiness_policy.py`
+  — both real-kj), REQ-316 CAP-025 test (`test_regression_pilot.py`), Gitea
+  adapter tests (`test_deploy_workflow_invocation.py` +
+  `test_deploy_gitea_invocation.py` — assert no cross-repo `uses:`,
+  `ref: v1.25`, `secrets: inherit`), rotation workflow test
+  (`test_rotate_key_workflow.py`), CAP-025 test
+  (`test_deploy_workflow_env_input.py`).
+- The v1.25 `pytest.skip("kj not installed")` skips are gone — `_require_kj`
+  no longer skips (kj v0.0.3 installed). All kj-dependent tests exercise
+  the real engine.
+
+### Security
+
+- **No `NOVA_AWS_*` secrets in committed files.** `.env.secrets` is
+  gitignored and NOT tracked (`git ls-files` confirms). All `NOVA_AWS_*`
+  references in committed workflow files are `${{ secrets.* }}` placeholder
+  references — the correct pattern. The W6 fix (b237b3e) removed raw
+  `NOVA_AWS_*` from the shell env in `run_platform.sh`'s local fallback.
+- **No forge mentions in synced files.** `test_no_forge_mentions` PASS
+  (the REQ-230 guard). The W6/W7 fix (03edd82) renamed `NOVA_GITEA_TOKEN`
+  → `NOVA_FORGE_TOKEN` (forge-agnostic) after the guard tripped.
+
+### Maintainability
+
+- **No stale `TYPE_MAP` refs in active docs.** The P4 W2 fix (a0799f1)
+  fixed the stale `TYPE_MAP`/`INPUT_MAP` references in `adapters/README.md`
+  (IDEATE I8). Remaining `TYPE_MAP` mentions are in `.ciagent/archive/`
+  (historical, correct) + `.ciagent/{CLARIFY,IDEATE,RESEARCH}.md`
+  (decision records, correct context).
+- **No new TODOs/FIXMEs in P3/P4.** `grep` over `core/` for
+  `TODO|FIXME|XXX|HACK` returns 0 matches.
+- The P3 W0.5 fix (3735330) resolved pre-existing P2 drift (dynamodb
+  `simple.yaml` → `simple.yml`, sync_workflows re-sync, CAP-024 deck path
+  → `nova-autonomous-cloud-delivery-marp.md`).
+
+### Review verdict
+
+**0 P0 issues remain** after the one P0 fix applied this phase (see §3).
+**P1+ issues for post-hoc review (none blocking ship):**
+
+| # | Severity | Issue | Disposition |
+|---|----------|-------|-------------|
+| R-1 | P2 (cosmetic) | `CHECKPOINT.json` `phase_branch` field is stale (`phase/03-pilot-metrics-and-policies`) — should be `phase/04-pilot-run-and-docs` or cleared. | Post-hoc. The orchestrator's ship step overwrites CHECKPOINT entirely (`stage: complete, phase: 5, phase_role: final`), so this field is transient. Not fixed here to avoid touching CHECKPOINT outside the ship step. |
+| R-2 | P3 (historical) | The v1.26 consumer-repo merge commit (78da051) + the P0 merge (d391cdf) use `---/ci---` close markers; the v1.26 platform-repo commits (P3/P4) use `---ci---` only. Minor format inconsistency from the multi-project boundary. | Post-hoc. Cosmetic; both markers are recognized by the audit tooling. |
+| R-3 | P3 (future-hardening) | Single `NOVA_AWS_*` root-equivalent key (D-207). Documented in PLAN.md §Future Hardening — a future milestone should split into `NOVA_BOOTSTRAP_AWS_*` + least-privilege `NOVA_AWS_*` runner key. | Post-hoc. Out of v1.26 scope by design (D-207, G-Q9). |
+
+---
+
+## 2. Audit (ciagent-audit equivalent)
+
+### 2.1 Reconstruction test — **PASS**
+
+The git log `---ci---` blocks are consistent with the `.ciagent/` file
+states. The last 20 commits on `milestone/v1.26-pilot-activation` show the
+expected phase progression:
+
+- P0 (`d391cdf`, status: complete) → P1 ship (`2ee541f`) →
+  P2 reconcile (`d022ddc`) → P2 complete (`6a3d47e`) →
+  P3 W0.5 → W2 → W3 → W4 → W5 → W6 → W6/W7 → verify (`5d1a985`) →
+  docs (`732998b`) → merge+complete (`268f695`, `6b60c0c`) →
+  P4 W1 (`cec34ab`, `6ced8ed`) → W2 (`a0799f1`) → verify (`074ee05`) →
+  merge+complete (`6eb7af2`, `f266dcf`).
+
+Each phase follows the `execute → verify → complete` lifecycle. The
+CHECKPOINT `current_phase` (phase 4, status complete, tag v1.25.4) matches
+the latest commit (`f266dcf docs(ship): P4 complete → v1.25.4`). The
+`previous_phase` (phase 3, tag v1.25.3, complete) is consistent.
+
+All 4 merge commits on the milestone branch (d391cdf, 78da051, 268f695,
+6eb7af2) carry `---ci---` blocks with project/phase/milestone/status.
+
+### 2.2 `.ciagent/` file discipline — **CLEAN** (after the one P0 fix)
+
+- **CHECKPOINT.json:** `current_phase` (4/complete/v1.25.4) + `previous_phase`
+  (3/complete/v1.25.3) consistent with the git log. `waves` map + `pre_run`
+  map + `notes` accurately describe the P4 live apply + outcome backfill.
+  One stale field: `phase_branch` (R-1, post-hoc).
+- **REQUIREMENTS.md:** v1.26 traceability table now shows all 13 REQs
+  (310..322) complete. **One P0 fix applied:** REQ-316 row corrected from
+  "P4 live-verify pending" → "v1.25.4 — live-verify complete" (P4 is
+  complete; v1.25.4 tagged; the live apply against 581513795199 succeeded
+  per commit 6ced8ed + verify 074ee05). The v1.25 table (REQ-291..309) is
+  all-complete + consistent with ROADMAP.
+- **ROADMAP.md:** v1.26 phases P0..P4 marked complete; P5 marked "planned"
+  (correct — this phase is in progress, ship is next). v1.25 marked
+  complete. The phase descriptions match the commits.
+- **PLAN.md:** the active phase plan covers P0..P5 with wave ordering,
+  persona assignment, + the REQ-322→P2 W0 revision. Consistent with what
+  shipped.
+- **ARCHITECTURE.md:** §12.8 (Pilot Estate) + §12.9 (rotation) present
+  (P4 W2 docs).
+- **PROJECT.md:** v1.26 active milestone noted; multi-project mode
+  (`nova-blockchain-exchange`) reflected.
+
+### 2.3 Branch hygiene — **CLEAN**
+
+`git branch -a` (local):
+- `main`
+- `milestone/v1.26-pilot-activation`
+- `phase/05-final-review-ship` (current)
+
+P1..P4 phase branches are deleted (only milestone + P5 remain, as
+required). Remote: `origin/main` + `origin/milestone/v1.26-pilot-activation`
+mirror the local state.
+
+Tags: `v1.25` (floating) + `v1.25.0` + `v1.25.1` + `v1.25.2` + `v1.25.3` +
+`v1.25.4` all exist. `v1.25.5` is not yet present (correct — it's the
+orchestrator's ship step).
+
+### 2.4 Commit discipline — **CLEAN**
+
+Every v1.26-scope commit on the milestone branch carries a `---ci---`
+block with `project` + `phase` + `milestone` + `status` (and most carry
+`wave`). The 4 merge commits (d391cdf, 78da051, 268f695, 6eb7af2) all
+carry `---ci---` blocks. (Historical commits from v1.0-v1.18 predate the
+block convention — out of scope for this audit.)
+
+The consumer-repo merge (78da051) correctly carries
+`project: nova-blockchain-exchange` (multi-project boundary respected);
+the platform commits carry `project: acdl`.
+
+### Audit verdict
+
+| Check | Result | Detail |
+|-------|--------|--------|
+| Reconstruction test | **PASS** | git-log `---ci---` blocks ↔ `.ciagent/` consistent; phase 4/complete/v1.25.4 matches HEAD. |
+| File discipline | **CLEAN** | All 6 `.ciagent/` files consistent after the REQ-316 P0 fix. One stale `phase_branch` field (R-1, post-hoc). |
+| Branch hygiene | **CLEAN** | Only main + milestone + P5; P1-P4 deleted; v1.25.0..v1.25.4 tagged. |
+| Commit discipline | **CLEAN** | All v1.26 commits carry `---ci---` blocks; merge commits included. |
+
+---
+
+## 3. P0 fixes applied this phase
+
+| # | File | Fix |
+|---|------|-----|
+| P0-1 | `.ciagent/REQUIREMENTS.md` | REQ-316 traceability row: "P4 live-verify pending" → "v1.25.4 — live-verify complete". P4 is complete (v1.25.4 tagged, live apply against 581513795199 succeeded per commits 6ced8ed + 074ee05); the "pending" text was stale documentation drift that misstated the milestone state. |
+
+No code-level P0 issues found — the P3/P4 feat/fix commits deliver what
+they claim; the test suite is green; no secrets leaked; no forge mentions;
+no stale active-doc references.
+
+---
+
+## 4. Overall verdict — **PROCEED to milestone ship**
+
+- **Review:** 0 P0 issues remain (1 P0 fix applied: REQ-316 doc drift).
+  3 P1+ items flagged for post-hoc (R-1 stale CHECKPOINT field, R-2 close-
+  marker inconsistency, R-3 future key-split — none block ship).
+- **Audit:** reconstruction PASS; file discipline CLEAN; branch hygiene
+  CLEAN; commit discipline CLEAN.
+- **Tests:** 844 passed, 0 failed, 0 unexpected skips (5 slow tests
+  individually confirmed green: 2 local-e2e + 3 regression-mode).
+
+**Decision: PROCEED.** The orchestrator's next step (Wave 3 milestone
+ship: merge `phase/05-final-review-ship` → `milestone/v1.26-pilot-
+activation` → `main`; tag `v1.25.5`; Gitea release; delete milestone
+branches; final CHECKPOINT clear) is unblocked. Per the full-autonomy
+"never halt" directive, even if a P0 had been critical, the ship step
+would still proceed with the issue documented — but here the single P0
+was a cosmetic doc-drift, now fixed.

+**Result:** the check could not complete — no AWS credentials were
+available in the P1 execute environment (`Unable to locate credentials.
+You can configure credentials by running `aws configure`.`). This is
+the "fail gracefully" path documented in the task spec: provisioning is
+**not attempted** from this environment because the required IAM grants
+are not confirmed for the execute principal.
+
+**Classification:** P1 blocker for the CodeArtifact mode of the publish
+workflow's wheel-upload step. The workflow ships with a fallback mode
+(see §3) so the pipeline is not blocked on CodeArtifact provisioning —
+it can publish to a private wheel index instead.
+
+## 2. Required IAM grants (for a follow-up provisioning task)
+
+To provision + use CodeArtifact as the wheel index, the principal that
+runs the publish workflow (OIDC role `nova-publish-*` or the spike
+runner) needs the following grants in account `581513795199`:
+
+| Action | Scope (example) | Purpose |
+| --- | --- | --- |
+| `codeartifact:CreateDomain` | `arn:aws:codeartifact:us-east-1:581513795199:domain/nova` | create the `nova` domain |
+| `codeartifact:CreateRepository` | `arn:aws:codeartifact:us-east-1:581513795199:repository/nova/*` | create `nova-pypi` (pypi-format) |
+| `codeartifact:GetRepositoryEndpoint` | `arn:aws:codeartifact:us-east-1:581513795199:repository/nova/nova-pypi` | get the twine/pip endpoint |
+| `codeartifact:GetAuthorizationToken` | `arn:aws:codeartifact:us-east-1:581513795199:domain/nova/*` | mint short-lived upload token |
+| `codeartifact:ReadFromRepository` | `arn:aws:codeartifact:us-east-1:581513795199:repository/nova/nova-pypi` | pip install (consumers + the composite action) |
+| `codeartifact:PublishPackageToRepository` | `arn:aws:codeartifact:us-east-1:581513795199:repository/nova/nova-pypi` | twine upload |
+| `ssm:PutParameter` / `ssm:GetParameter` | `arn:aws:ssm:us-east-1:581513795199:parameter/nova/layer/*` | CAP-035 version↔ARN mapping |
+| `lambda:PublishLayerVersion` | `arn:aws:lambda:us-east-1:581513795199:layer:nova-cli` | Lambda layer publish |
+| `iam:CreateRole` / `iam:PassRole` (already held) | — | only if a dedicated publish OIDC role must be created |
+
+The domain + repository to provision:
+
+- **Domain:** `nova`
+- **Repository:** `nova-pypi` (format: `pypi`)
+- **Endpoint (twine/pip):**
+  `https://nova-581513795199.d.codeartifact.us-east-1.amazonaws.com/pypi/nova-pypi/`
+
+Once provisioned, set the repository secret `NOVA_CODEARTIFACT_DOMAIN=nova`
+on both forges and the publish workflow + composite action will switch
+to CodeArtifact mode automatically (see §3).
+
+## 3. Fallback: private wheel index (`NOVA_WHEEL_INDEX`)
+
+Both the publish workflow (`.github/workflows/publish.yml` and its
+byte-identical mirror on the dev forge) and the composite action
+(`.github/actions/nova-cli/action.yml`) support a **fallback mode** that
+does not require CodeArtifact. The selection is env/secret driven:
+
+| Mode | Trigger | Upload target | Install source |
+| --- | --- | --- | --- |
+| **CodeArtifact** | `NOVA_CODEARTIFACT_DOMAIN` env/secret is set | `aws codeartifact login --tool twine` → twine uploads to the CodeArtifact pypi endpoint | `aws codeartifact login --tool pip` → `pip install nova==<ver>` |
+| **Fallback index** | `NOVA_CODEARTIFACT_DOMAIN` unset; `TWINE_REPOSITORY_URL` + `TWINE_USERNAME` + `TWINE_PASSWORD` set | `twine upload` to `TWINE_REPOSITORY_URL` | `pip install --index-url $NOVA_WHEEL_INDEX nova==<ver>` |
+
+The fallback index can be any PEP 503-compliant simple index — e.g. a
+private package registry hosted on the dev forge, a self-hosted
+`pypiserver`, or a static S3-backed index. The workflow does not hardcode
+the index URL; it is supplied via the `NOVA_WHEEL_INDEX` env var (for
+consumers / the composite action) and `TWINE_REPOSITORY_URL` (for the
+publish step). This keeps the forge/registry choice deployment-specific
+and avoids baking any single hostname into the synced workflow files.
+
+### 3.1 Fallback index shape (when self-hosted)
+
+A minimal PEP 503 simple index served from a private registry is
+sufficient. The only required layout per package:
+
+```
+/nova/
+  index.html                         # links to each version's page
+  /nova-<version>-py3-none-any.whl   # the wheel (publish workflow uploads this)
+```
+
+The publish workflow uploads `dist/nova-<version>-*.whl` via `twine
+upload` to `TWINE_REPOSITORY_URL`; consumers install via
+`pip install --index-url "$NOVA_WHEEL_INDEX" nova==<version>`.
+
+## 4. CAP-035 invariant (unaffected by the index choice)
+
+Regardless of which wheel index is used, the Lambda layer ARN ↔ wheel
+version mapping is recorded in SSM and is the source of truth for
+CAP-035:
+
+```
+/nova/layer/nova-cli/version = "<wheel-version>:<layer-arn>"
+```
+
+e.g. `1.14.0:arn:aws:lambda:us-east-1:581513795199:layer:nova-cli:3`.
+The publish workflow writes this parameter atomically after both the
+wheel upload and the layer publish succeed; if either fails the job
+fails (merge blocked, REQ-323 AC).
+
+## 5. Open follow-ups
+
+1. Provision CodeArtifact domain `nova` + repository `nova-pypi` in
+   `581513795199` once the `codeartifact:*` grants in §2 are attached to
+   the publish OIDC role. Update this document with the confirmed ARN +
+   endpoint.
+2. Set the `NOVA_CODEARTIFACT_DOMAIN` repository secret on both forges
+   to switch the publish workflow + composite action from fallback-index
+   mode to CodeArtifact mode.
+3. Until §1 is done, the fallback index must be provisioned out of band
+   and its URL exposed to consumers via the `NOVA_WHEEL_INDEX` env var
+   (and to the publish workflow via the `TWINE_*` secrets).

+"""NFR-11 / REQ-326 AC: byte-identical Nova CLI composite action.
+
+This test verifies the structural invariants of the `nova cli-action`
+composite action at `.github/actions/nova-cli/action.yml`. The action is
+discovered by both the production forge (GitHub Actions) and the dev
+forge (act_runner) via the same `.github/actions/nova-cli/` path, so a
+single source file under test guarantees both platforms consume the
+same bytes — which is the byte-identical requirement (NFR-11).
+
+What this unit test can verify (structural invariants):
+  (a) action.yml is valid YAML
+  (b) name is present + non-empty
+  (c) inputs.command is required (the action's contract)
+  (d) inputs.contract / mode / version exist with their documented
+      defaults
+  (e) runs.using == "composite"
+  (f) a setup-python step pins python-version to "3.12" (REQ-326 AC3)
+  (g) an install step exists that installs `nova` (CodeArtifact default
+      or fallback-index path)
+  (h) a run step executes `nova ${{ inputs.command }}`
+
+What this unit test CANNOT verify (and intentionally does not):
+  The full byte-identical cross-platform verification (NFR-11,
+  REQ-326 AC2) requires running the action with identical inputs on a
+  production-forge ubuntu-latest runner AND a dev-forge act_runner, then
+  asserting identical stdout + exit code. That is a CI matrix job
+  (matrix over the two forges), not a unit test — it cannot be
+  reproduced in-process because it depends on two external runner
+  environments. The structural invariants below are the unit-testable
+  subset: if the single action.yml source is structurally correct and
+  both forges consume the same file path, the byte-identical guarantee
+  reduces to "the file does not branch on the forge identity" — which
+  the assertions below enforce (no forge-specific conditionals, single
+  install path selected by env, single run step).
+
+  The CI matrix job that completes the NFR-11 verification is defined
+  out-of-band (a workflow that invokes this action on both forges with
+  a fixed `command: --version` and asserts the outputs match). It is
+  not part of this pytest suite.
