feat(P53): local emulating adapters (D-092) — full local E2E, no AWS

The platform is now fully locally testable without cloud credentials.
The headline E2E (contract -> resolver -> adapter -> S3 state -> ECS
service -> DynamoDB outbox -> contract-ingestor Lambda) runs end-to-end
against the local emulating tier (D-092, REQ-113).

Four local emulating adapters in core/local_emulators.py:
- FlatFileOutbox: flat-file DynamoDB outbox emulator (hash-chained JSONL;
  resumable across instances; chain verification).
- LocalEcsEmulator: local ECS Fargate HTTP 200 emulator (free-port
  binding on 127.0.0.1; 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_platform.sh gains a --local flag that short-circuits to the local
emulating tier (no AWS, no Checkov, no DynamoDB).

Regression gate (D-091) now covers 12 capabilities (was 10): +CAP-011
(local E2E microservice) + CAP-012 (local E2E static-assets).

Verified: 513 fast tests pass (was 502; +11 new). 2 slow local E2E
tests pass. run_regression.sh reports 12/12 Verified. run_platform.sh
--local exits 0 with LOCAL E2E OK. No AWS credentials required.

# Phase 52 — Verify (v1.10) — Pipeline Regression-VERIFY Fix
# Phase 53 — Verify (v1.10) — Local Emulating 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).
**VERIFY PASS**the platform is now fully locally testable without
cloud credentials (D-092). The headline E2E runs end-to-end against the
local emulating tier: contract -> resolver -> adapter -> local S3 backend
-> local ECS (HTTP 200) -> flat-file outbox (chain verified) -> local
Lambda (200). 513 offline tests pass; the regression gate covers 12
capabilities including the local E2E. No AWS required for Phase 53.

"""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).
