### Phase 53 — local-emulating-adapters
- **Description:** Build local emulating adapters so the platform is fully locally testable without cloud credentials: flat-file DynamoDB outbox, local ECS emulator (synthetic HTTP 200 from local shell), local S3 state backend (flat-file tfstate), local Lambda stub (in-process handler invocation). Same interfaces as the live adapters.

## Structural
-- `core/regression_verify.py` — new module implementing regression-class
- VERIFY (D-091). 10 seeded local-tier capability checks (CAP-001..CAP-010).
-- `scripts/run_regression.sh` — shell wrapper invoking the module; writes
- `.ciagent/REGRESSION_REPORT.md` + `.json`; exits non-zero on any
- non-Verified capability (fails closed).
-- `tests/test_verify_regression_mode.py` — 11 tests (8 fast + 3 slow).
-- `pyproject.toml` — `slow` marker registered; `run_ci.sh` excludes slow
- tests to avoid recursion.
-- Existing diff-scoped VERIFY artifacts (`run_ci.sh`, `run_platform.sh`,
- `.ciagent/VERIFY.md` per-phase record) preserved unchanged in behavior.
+- `core/local_emulators.py` — new module with four local emulating
+ adapters (D-092, REQ-113):
+ - `FlatFileOutbox` — flat-file DynamoDB outbox emulator (hash-chained
+ JSONL; resumable across instances; chain verification).
+ - `LocalEcsEmulator` — local ECS Fargate HTTP 200 emulator (free-port
+ binding; health check; clean destroy).
+ - `LocalS3StateBackend` — rewrites the terraform S3 backend to a local
+ backend (per-stack tfstate in a temp folder).
+ - `LocalLambdaStub` — invokes the contract_ingestor handler in-process
+ (patches `_get_dynamodb` / `_get_secrets_client` / `urllib.urlopen`;
+ DynamoDB writes redirected to the FlatFileOutbox).
+ - `run_local_e2e()` — runs the full headline E2E against the local tier.
+- `scripts/run_platform.sh` — `--local` flag added; short-circuits to the
+ local emulating tier (no AWS credentials, no Checkov, no DynamoDB).
+- `tests/test_local_emulating_adapters.py` — 13 tests (11 fast + 2 slow).
+- `core/regression_verify.py` — CAP-011 + CAP-012 added (local E2E for
+ microservice + static-assets stacks).
+- `scripts/run_regression.sh` — now covers 12 capabilities (was 10).
**PASS.**
## Behavioral
-- `pytest tests/ -m "not slow"`: 502 passed, 3 deselected (was 493 at
- v1.9; +9 new fast tests). No regressions.
-- `pytest tests/test_verify_regression_mode.py -m slow`: 3 passed
- (integration: seeded registry runs honestly; regression mode is
- additive; decay-surfacing confirms the gate fails closed).
-- `bash scripts/run_regression.sh`: all 10 seeded local-tier
- capabilities Verified against current code; gate passes; report
- written to `.ciagent/REGRESSION_REPORT.{md,json}`.
-- Decay-surfacing test (`test_regression_surfaces_decay_when_seeded_with_broken_check`)
- injects a deliberately-broken cloud-backed check and confirms the run
- tags it Broken and fails closed. **PASS.**
+- `pytest tests/ -m "not slow"`: 513 passed, 5 deselected (was 502 at
+ Phase 52; +11 new fast local-emulator tests). No regressions.
+- `pytest tests/test_local_emulating_adapters.py -m slow`: 2 passed
+ (headline E2E: microservice + static-assets against the local tier).
+- `python3 core/local_emulators.py contracts/microservice.yaml`: full
+ local E2E runs end-to-end (contract -> resolver -> adapter -> local S3
+ backend -> local ECS HTTP 200 -> flat-file outbox chain verified ->
+ local Lambda 200). No AWS credentials required.
+- `bash scripts/run_platform.sh --local contracts/microservice.yaml`:
+ exits 0 with "LOCAL E2E OK".
+- `bash scripts/run_regression.sh`: 12/12 capabilities Verified (was
+ 10/10; +2 local E2E checks). **PASS.**
## Security
-- No new credentials, network calls, or cloud mutations introduced.
-- The regression module runs subprocess checks in the local shell only;
- the live-AWS tier is deferred to Phase 54 (D-093).
-- No secrets logged; subprocess output is truncated to 200/300 chars in
- report detail fields. **PASS.**
+- No AWS credentials, network calls, or cloud mutations introduced.
+- The local ECS emulator binds to 127.0.0.1 only (loopback; no external
+ exposure). The HTTP server is daemon-threaded and shut down on destroy.
+- The local Lambda stub patches `urllib.urlopen` to a fake response so
+ the `report_error` action does not hit the GitHub/Gitea API.
+- No secrets logged; the secrets stub returns a static "local-stub" token.
+ **PASS.**
## Quality
-- `test_verify_regression_mode.py` covers: all-Verified passes;
- one-Decayed blocks; one-Broken blocks; check-raising is Broken;
- report serialization; md+json output; broken-subprocess is Broken;
- missing-executable is Broken; seeded registry runs honestly;
- regression mode is additive (diff-scoped behavior preserved);
- decay-surfacing (gate fails closed on injected Broken). **PASS.**
+- `test_local_emulating_adapters.py` covers: outbox write + chain link +
+ broken-chain detection + cross-instance resume; ECS HTTP 200 + destroy
+ stops server; S3->local backend rewrite + per-stack state path; Lambda
+ stub happy path + missing-field 400; `is_local_tier` flag; the full
+ headline E2E for both stacks (microservice with ECS, static-assets
+ without). **PASS.**
## Verdict
-**VERIFY PASS** — regression-class VERIFY (D-091) implemented and tested.
-The gate catches decay (fails closed). Existing diff-scoped VERIFY
-behavior preserved. 502 offline tests pass; no AWS required for Phase 52.
-
-## Diff-scoped VERIFY defect (recorded for traceability)
-
-The prior VERIFY stage was diff-scoped: it checked the phase diff only
-and never re-runs underlying platform capability. This let 8 NFR-patch
-phases (v1.9.1→v1.9.8, deck rework) pass VERIFY while the platform they
-described decayed underneath. The defect is recorded as D-091 and
-remediated by `core/regression_verify.py`. The regression run is now a
-milestone-completion gate (D-091). Cloud-backed capability re-verification
-(live ECS, DynamoDB writes, Lambda invocation) lands in Phase 54 (D-093).

+"""Local emulating adapters (D-092, REQ-113).
+
+The platform must be fully locally testable without cloud credentials.
+These adapters emulate the four cloud-backed interactions the platform
+uses, so the headline E2E (contract submission -> service live ->
+evidence event) runs end-to-end against the local tier with no AWS:
+
+ 1. FlatFileOutbox - emulates the DynamoDB outbox (core/outbox_writer.py)
+ 2. LocalEcsEmulator - emulates an ECS Fargate service returning HTTP 200
+ 3. LocalS3StateBackend - rewrites the terraform S3 backend to a local backend
+ 4. LocalLambdaStub - invokes the contract_ingestor handler in-process
+
+Each adapter exposes the same interface as the live counterpart so the
+caller code path is unchanged; only the I/O target swaps. Selection is
+gated on the ACDL_LOCAL_TIER env var (set by run_platform.sh --local).
