- Response-shape contract stability preserved for touched handlers/services.
- Remaining risk is primarily external dependency behavior on valid-hash happy paths in local environments (relay/storage), not hash-bypass behavior.
## Phase 15 hardening status (2026-03-13)
- Working branch created from `origin/SIPS-Development`:
- `TASK22028-phase15-hardening-slice`
- Delivered consistency-only hardening across 4 additional sensitive file handlers:
- `pages/api/file/upload.js`
- `pages/api/file/uploadsinglefile.js`
- `pages/api/file/createappealcompletemessage_api.js`
- `pages/api/file/setupcontainer.js`
- Hardening posture updates:
- standardized explicit early 400 on missing hash where validation was already required
- standardized early hash-mismatch return path style in `setupcontainer`
- preserved response-shape/signature contracts (no intended contract changes)
- Added focused phase-15 tests:
- `tests/phase15/service-behaviour.test.cjs`
- negative-path checks for missing/invalid hash across all selected handlers
- required-input negative-path checks where applicable
- one valid-hash mocked happy-path check (`setupcontainer` response shape)
### Phase 15 validation evidence snapshot
- `node tests/phase6/service-parity.test.cjs` -> pass
- `node tests/phase6/service-behaviour.test.cjs` -> pass (8/8)
- `node tests/phase7/service-behaviour.test.cjs` -> pass (10/10)

- `node tests/phase13/service-behaviour.test.cjs` -> pass (7/7)
- `node tests/phase14/service-behaviour.test.cjs` -> pass (5/5)
- `node tests/phase15/service-behaviour.test.cjs` -> pass (5/5)
- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps` warnings)
### Phase 15 manual HTTP snapshot
- Dev server run on `http://localhost:3002`.
- Missing/invalid hash negative-path checks for selected handlers -> **400**.
- Missing required params where applicable -> **400**.
- Valid-hash spot-check:
- `GET /api/file/setupcontainer?ident=c1&hash=<valid>` -> **200**.
## Likely next steps
1. Stabilize and simplify breadcrumb/back-link decision logic with focused regression checks.

### CL-026: Phase 15 hardening — consistency guards for additional hash-sensitive file handlers
date: 2026-03-13
author: Cline
scope: `pages/api/file/{upload,uploadsinglefile,createappealcompletemessage_api,setupcontainer}.js`, `tests/phase15/service-behaviour.test.cjs`, `memory-bank/*`
type: change
rationale: Deliver a small reversible consistency-only hardening slice by standardizing missing/invalid hash negative paths and required input handling in additional sensitive file handlers.
impact: Consistent early 400 behavior for missing/invalid hash and missing required params while preserving existing response shapes/signatures.
status: completed
Summary:
- Started new branch from `origin/SIPS-Development`: `TASK22028-phase15-hardening-slice`.
- Applied minimal hardening updates:
- `upload.js`: explicit missing-hash guard before hash comparison.
- `uploadsinglefile.js`: explicit missing-hash guard before hash comparison.
- `createappealcompletemessage_api.js`: added missing-hash guard to existing required-input guard block.
- `setupcontainer.js`: standardized to early-return on hash mismatch; contract and status behavior preserved.
- Added focused tests:
- `tests/phase15/service-behaviour.test.cjs`
- covers missing-hash negative paths for all selected handlers
- includes required-input negative paths and one valid-hash happy-path shape check.
Validation:
- `node tests/phase6/service-parity.test.cjs` -> pass
- `node tests/phase6/service-behaviour.test.cjs` -> pass (8/8)
- `node tests/phase7/service-behaviour.test.cjs` -> pass (10/10)
- `node tests/phase8/service-behaviour.test.cjs` -> pass (5/5)
- `node tests/phase9/service-behaviour.test.cjs` -> pass (5/5)
- `node tests/phase10/service-behaviour.test.cjs` -> pass (5/5)
- `node tests/phase11/service-behaviour.test.cjs` -> pass (4/4)
- `node tests/phase12/service-behaviour.test.cjs` -> pass (4/4)
- `node tests/phase13/service-behaviour.test.cjs` -> pass (7/7)
- `node tests/phase14/service-behaviour.test.cjs` -> pass (5/5)
- `node tests/phase15/service-behaviour.test.cjs` -> pass (5/5)
- `npm run lint` -> warnings only (pre-existing hook dependency warnings)
- Manual checks on `localhost:3002`:
- invalid/missing hash for each selected handler -> 400
- missing required params where applicable -> 400
- valid-hash spot-check (`setupcontainer`) -> 200
Follow-ups:
- Continue small-batch consistency hardening for remaining sensitive handlers where guard patterns are still inconsistent.
- Keep manual happy-path checks constrained to feasible local dependencies; document downstream/environment-caused failures separately.

## Latest update (2026-03-13 — Phase 15 hardening slice)
- New branch created from `origin/SIPS-Development` with confirmed work item prefix:
- `TASK22028-phase15-hardening-slice`
- Delivered a small consistency-only hardening slice across 4 additional sensitive file handlers:
- `pages/api/file/upload.js`
- `pages/api/file/uploadsinglefile.js`
- `pages/api/file/createappealcompletemessage_api.js`
- `pages/api/file/setupcontainer.js`
- Scope delivered:
- standardized explicit early 400 handling for missing hash in handlers where hash validation was present but missing-hash guard was inconsistent
- standardized guard style in `setupcontainer` to early-return on hash mismatch (same status/contract)
- standardized missing required hash handling in `createappealcompletemessage_api`
- preserved response shapes and signatures (no contract changes)
- Added focused phase-15 tests:
- `tests/phase15/service-behaviour.test.cjs`
- negative-path coverage for missing hash across all 4 handlers
- additional required-input checks where applicable
- one valid-hash happy-path contract check (`setupcontainer` -> 200 with existing response shape)

## Safe execution mode for migration chunks (required)
To reduce terminal hangs during bulk migration work, run refactor chunks in **safe stepwise mode** instead of long chained commands.
