# Progress — PEDW FrontEnd

## Completed / evidenced milestones

- Bilingual routing structure is established with extensive Welsh rewrites and locale namespace mapping.
- Next-auth + Prisma SQL Server persistence is integrated for user/session lifecycle.
- Broad API surface exists for search, case, portal, admin, and file/document operations.
- CRM/relay hash pattern is implemented across many endpoint handlers.
- Recent shipped updates focused on:
    - search/case back-navigation and breadcrumb behavior,
    - DNS/view-all navigation logic,
    - preferred-language handling for notify template selection,
    - PDF formatting/hyperlink fixes,
    - upload validation character updates.

## Work in progress signals

- Ongoing iterative fixes in breadcrumb/case-summary flows suggest navigation consistency is still being tuned.
- Mixed proxy/non-proxy endpoint implementations continue to evolve in parallel.
- Priority 1 refactor plan execution started for `actions/index.js` split (Phase 1 foundation complete).

## Planned / partially implemented (inferred from code state)

- Partial migration or coexistence of deployment/runtime patterns (Next runtime plus custom server artifacts).
- Continued refinement of document/email workflow behavior (template/language and formatting quality).
- Prioritized structural refactor backlog documented in `memory-bank/refactor-backlog.md`.

## Known technical debt

- `actions/services/legacyActionsService.js` still holds broad domain wrappers after Phase 1 extraction (core helpers now separated).
- Significant duplication of token/hash/relay logic across endpoint files.
- Inconsistent security/hash guard enforcement in some file routes.
- Sparse automated test coverage (`tests/` currently empty).
- Verbose logging in sensitive flows (auth/email/actions/file) increases privacy risk.

## Latest update (2026-03-12)

- Branch `0000-update-actions-monolith` created from development branch for Priority 1 refactor implementation.
- `actions/index.js` reduced to a compatibility barrel.
- New core helper modules added under `actions/core/`:
    - `env.js`
    - `logger.js`
    - `hash.js`
    - `token.js`
    - `headers.js`
- Existing action wrappers moved to `actions/services/legacyActionsService.js` and continue to be exported via the barrel for compatibility.
- `actions/clients/` scaffolded for upcoming client extraction phase.
- Phase 2 service grouping completed with dedicated service files and `actions/services/index.js` barrel.
- Export parity check confirms grouped service modules cover all legacy exported action names.
- Phase 3 migration started by moving selected high-churn consumers and representative endpoint handlers to direct `actions/services/*` and `actions/core/*` imports.
- Phase 4 hardening baseline added with new guard helpers and redacted logging, adopted in selected notify/login/contact API handlers.
- Additional Priority 1 consumer migration pass completed for high-use portal/form/representation helpers:
    - Updated direct service/core imports in:
        - `components/admin/tabs/documents.js`
        - `components/admin/tabs/storage.js`
        - `components/admin/utils/serverside.js`
        - `components/case/documents.js`
        - `components/case/representation/representationComplete.js`
        - `components/case/representation/representationElements.js`
        - `components/elements/index.js`
        - `components/myportal/awaitingsubmissionfromblob.js`
        - `components/myportal/topthree.js`
        - `components/myportal/topthree_reps.js`
        - `components/utils/index.js`
        - `lib/myportal/loadMyPortalAppealPage.js`
        - `lib/newappeal/loadNewAppealPage.js`
- Additional Priority 1 consumer migration pass completed for view-all/search/unsubscribe flows:
    - Updated direct service/core imports in:
        - `components/myportal/viewall.js`
        - `components/search/addresssearchresults.js`
        - `pages/unsubscribe/[watchlistid].js`
        - `pages/unsubscribeall/[watchlistid].js`
- Broad `actions` barrel import count reduced again; remaining non-comment usages are now concentrated in selected `pages/api/endpoint/*` and `pages/api/file/*` handlers.
- Additional Priority 1 endpoint/file proxy migration chunk completed:
    - Updated imports in:
        - `pages/api/endpoint/getmylpacases_api.js`
        - `pages/api/endpoint/getbasicdnssearchpaged_api.js`
        - `pages/api/endpoint/getsearchdocumentdetailspaged_api.js`
        - `pages/api/endpoint/getbasicsearchpaged_api.js`
        - `pages/api/file/getawaitingsubmissionfromblobproxy.js`
        - `pages/api/file/getrepsblobproxy.js`
        - `pages/api/file/getbloblistproxy.js`
        - `pages/api/file/createappealcompletemessageproxy_api.js`
    - Migrated from broad `../../../actions` imports to focused `actions/core/*` + service imports.
    - Removed duplicated local hash helper in `getmylpacases_api.js` and reused `actions/core/hash`.
- Broad `actions` import scan now reports only comment-only references (no active broad imports in `.js` files).
- Lint check re-run outcome unchanged: `next lint` fails due legacy/unsupported ESLint options in repo tooling config (not introduced by this refactor pass).

## Handover update (2026-03-13)

- Priority 1 import-migration wave has been checked in and completed via pull request.
- Recent migration commits captured in this wave:
    - `f0202bb`
    - `fa98535`
    - `bef8f25`
- Active broad `.../actions` imports are now eliminated from live `.js` code paths.
- Next refactor phase will begin on a **new branch** and focus on splitting `actions/services/legacyActionsService.js` into smaller direct implementation modules.
- Recommended decomposition order for the new branch:
    1. reference/search extraction
    2. portal/document extraction
    3. compatibility layer slimming + dead wrapper removal

## Latest update (2026-03-13 — Phase 5 kickoff)

- New branch created from `SIPS-Development`: `TASK21997-phase5-legacyactions-split`.
- Completed first Phase 5 decomposition slice from `legacyActionsService`:
    - Added `actions/services/searchDirectService.js`
    - Added `actions/services/referenceDataDirectService.js`
    - Updated `actions/services/searchService.js` to source from `searchDirectService`
    - Updated `actions/services/referenceDataService.js` to source from `referenceDataDirectService`
- Compatibility approach preserved: public grouped service exports and function signatures remain unchanged for callers.
- Validation status unchanged:
    - `npm run lint` still fails due pre-existing Next/ESLint option incompatibility in repo tooling configuration.

## Latest update (2026-03-13 — Phase 5 document slice)

- Continued on branch `TASK21997-phase5-legacyactions-split`.
- Completed second decomposition slice from `legacyActionsService`:
    - Added `actions/services/documentDirectService.js`
    - Updated `actions/services/documentService.js` to source from `documentDirectService`
- Compatibility approach preserved:
    - grouped service export names/signatures unchanged for consumers.
- Verification:
    - service import scan now shows remaining legacy-backed grouped modules are:
        - `portalService`, `accountService`, `caseService`, `adminService`, `notifyService`, `integrationService`
    - `npm run lint` passes with warnings only (no blocking errors).

## Latest update (2026-03-13 — Phase 5 completion)

- Continued decomposition and completed all remaining slices on `TASK21997-phase5-legacyactions-split`:
    - portal direct extraction
    - account + case direct extraction
    - admin + integration + notify direct extraction
    - legacy cleanup/removal
- New direct modules now in place:
    - `portalDirectService.js`
    - `accountDirectService.js`
    - `caseDirectService.js`
    - `adminDirectService.js`
    - `integrationDirectService.js`
    - `notifyDirectService.js`
- `actions/services/legacyActionsService.js` removed after import parity checks.
- Validation evidence:
    - `actions/services` import scan: zero `./legacyActionsService` references
    - `npm run lint`: warnings only, no blocking errors
    - `npm run build`: successful production build

## Latest update (2026-03-13 — Phase 6 post-Phase-5 hardening, in progress)

- Branch created from `SIPS-Development`: `TASK21998-phase6-postphase5-hardening`.
- Added focused parity checks for grouped/direct service stability and service index barrel stability:
    - `tests/phase6/service-parity.test.cjs`
    - validates grouped service import/export parity across:
        - search, referenceData, document, portal, account, case, admin, integration, notify
    - validates `actions/services/index.js` export list stability/order.
- Added shared service error helper:
    - `actions/services/httpServiceUtils.js`
    - centralizes common `consoleLogger + return error.response` and `ErrResponse` shape patterns.
- Applied low-risk duplication reduction in direct services (no signature/shape changes intended):
    - `searchDirectService.js`
    - `referenceDataDirectService.js`
    - `caseDirectService.js`
    - `adminDirectService.js`
- Logging cleanup/redaction-oriented hardening (sensitive-flow noisy logs removed):
    - removed debug `console.log` statements from:
        - `searchDirectService.js`
        - `documentDirectService.js`
        - `portalDirectService.js`
        - `caseDirectService.js`
        - `adminDirectService.js`

### Validation snapshot (Phase 6)

- `node tests/phase6/service-parity.test.cjs` -> **pass**
- `node tests/phase6/service-behaviour.test.cjs` -> **pass** (8/8)
- `npm run lint` -> **warnings only** (same pre-existing warnings)

### Decision captured (Phase 6)

- Agreed approach: keep parity guard tests **and** add focused behavioural unit tests in the current refactor stream (instead of deferring all behavioural checks to long-term roadmap).
- Implemented now:
    - `tests/phase6/service-behaviour.test.cjs`
    - mocked-axios behavioural checks for critical success/error contracts across search/reference/case/admin direct services.
- Wider behavioural expansion remains on roadmap for additional domains/functions.

### Targeted smoke snapshot (local dev server)

- Search flow:
    - `GET /searchresults` (EN/CY) -> **500** in local env due existing serialization issue (`initialState.search.searchString` undefined in SSR payload), observed in `/tmp/phase6-dev.log`.
    - `GET /advancedsearch` and `GET /cy/advancedsearch` -> **200**
- Case flow:
    - `GET /case` and `GET /cy/case` -> **200**
- My Portal flow (negative-path):
    - `GET /myportal` and `GET /cy/myportal` -> **307** redirect to `/auth/signin` (expected unauthenticated behavior)
- Document flow (negative-path):
    - `GET /api/file/getbloblistproxy?container=test&casefolderID=test` -> **400**
- Notify flow (negative-path):
    - `POST /api/email/notify` with `{}` -> **400**

## Latest update (2026-03-13 — Phase 8 hardening slice)

- New branch created from `origin/SIPS-Development` with work item prefix:
    - `TASK22017-phase8-hardening-slice`
- Hardened four sensitive API handlers with minimal reversible guards:
    - `pages/api/file/deleteblobcase.js`
    - `pages/api/file/deleteblobrep.js`
    - `pages/api/file/createappealcompletemessage_api.js`
    - `pages/api/endpoint/getportallogin_api.js`
- Scope delivered:
    - re-enabled/enforced hash checks where bypassed/commented
    - standardized early 400 negative paths for missing/invalid required query inputs
    - reduced noisy sensitive-path logging and routed errors through `consoleLogger`
    - preserved function signatures and existing response-shape contracts
- Consumer parity updates (required to preserve behaviour after hash enforcement):
    - `actions/services/documentDirectService.js`
        - append hash for delete-blob-case/delete-blob-rep calls
    - `actions/services/portalDirectService.js`
        - append hash for create-appeal-complete-message call (hash path preserved to existing API contract)
- Added focused tests:
    - `tests/phase8/service-behaviour.test.cjs`
    - covers negative paths for all 4 handlers (missing/invalid hash and missing key params as applicable)
    - includes one happy-path check for `getportallogin_api` with valid hash via mocked dependencies

### Validation snapshot (Phase 8)

- `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)
- `npm run lint` -> **warnings only** (pre-existing react-hooks dependency warnings; no new lint errors)

### Manual HTTP checks (Phase 8)

- Local dev server on `http://localhost:3001`.
- Negative-path checks:
    - `GET /api/file/deleteblobcase?...` missing hash -> **400**
    - `GET /api/file/deleteblobcase?...&hash=bad` -> **400**
    - `GET /api/file/deleteblobrep?...` missing hash -> **400**
    - `GET /api/file/deleteblobrep?...&hash=bad` -> **400**
    - `GET /api/file/deleteblobrep?...` missing `repfile` -> **400**
    - `GET /api/file/createappealcompletemessage_api?...` missing hash -> **400**
    - `GET /api/file/createappealcompletemessage_api?...&hash=bad` -> **400**

    - `GET /api/endpoint/getportallogin_api?...&hash=bad` -> **400**
    - `GET /api/endpoint/getportallogin_api?...` missing `emailAddress` -> **400**
- Valid-hash spot-check:
    - `GET /api/endpoint/getportallogin_api?...&hash=<valid>` reached handler with valid hash but returned **400** from upstream relay/CRM call in local environment (expected environmental dependency risk, not hash-guard bypass).

## Latest update (2026-03-13 — Phase 9 hardening slice)

- New branch created from `origin/SIPS-Development` with work item prefix:
    - `TASK22019-phase-9-hardening`

    - `pages/api/file/upload.js`
    - `pages/api/file/uploadsinglefile.js`
    - `pages/api/file/setupcontainer.js`
- Scope delivered:
    - re-enabled/enforced hash validation where bypassed/commented
    - added/standardized early 400 negative paths for missing/invalid hash and missing key parameters
    - reduced noisy logging in sensitive file-upload/message paths
    - preserved handler signatures and external response-shape contracts
- Consumer parity updates:
    - `actions/services/portalDirectService.js`
        - append hash for `createrepcompletemessage_api` call
    - `actions/services/documentDirectService.js`
        - append hash for `upload` and `uploadsinglefile` calls
- Added focused tests:
    - `tests/phase9/service-behaviour.test.cjs`
    - covers negative paths across all 4 phase-9 handlers

- Valid-hash happy-path spot-check:
    - Completed using `.env.local` runtime key: `POST /api/file/uploadsinglefile?hash=<valid>` -> **200**

### Rollback plan (Phase 9)

1. Revert the four hardened API handlers.
2. Revert direct-service hash append changes in `documentDirectService` and `portalDirectService`.
3. Remove `tests/phase9/service-behaviour.test.cjs` if full slice rollback required.
4. Re-run phase6/7/8/9 baseline tests + lint after rollback.

    - `pages/api/file/getprogressobjblob.js`
    - `pages/api/file/getbloblist.js`
    - `pages/api/file/getrepsblob.js`
- Scope delivered:
    - added explicit early 400 handling for missing/empty required inputs (`container`, `casefolderID` where applicable, `hash`)
    - standardized hash-mismatch negative-path checks to early return 400
    - removed legacy/noisy commented debug blocks from touched handlers
    - preserved existing handler signatures and response-shape contracts
- Caller parity impact:
    - no new caller changes required in this slice because direct-service consumers already append hash for these APIs.
- Added focused tests:
    - `tests/phase10/service-behaviour.test.cjs`
    - covers negative paths for all 4 selected phase-10 handlers
    - includes one valid-hash contract-preserving happy-path check (`getbloblist` via mocked dependencies)

    - added explicit early 400 handling for missing/empty required query/body inputs (`hash`, `contactid`, `incidentid` as applicable)
    - standardized hash-mismatch negative-path checks for delete-blob handlers
    - removed noisy body/query logging in involvement handlers
    - preserved existing function signatures and response-shape contracts
- Added focused tests:
    - `tests/phase13/service-behaviour.test.cjs`
    - covers negative paths for selected phase-13 handlers
    - includes valid-hash/valid-body contract-preserving happy-path checks via mocked dependencies

### Validation snapshot (Phase 13)

- `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)
- `npm run lint` -> **warnings only** (pre-existing react-hooks warnings; no new lint errors)

### Manual HTTP checks (Phase 13)

- Negative-path checks on `localhost:3000`:
    - `GET /api/file/deleteblobcase?container=test&casefolderID=case-1` (missing hash) -> **400**
    - `GET /api/file/deleteblobcase?container=test&casefolderID=case-1&hash=bad` -> **400**
    - `GET /api/file/deleteblobrep?container=test&casefolderID=case-1&repfile=r.pdf` (missing hash) -> **400**
    - `POST /api/file/createcaseinvolvement_api` with `{}` -> **400**
    - `POST /api/file/createrepinvolvement_api` with `{}` -> **400**
- Valid-hash happy-path spot-check:
    - `GET /api/file/deleteblobcase?container=test&casefolderID=case-1&hash=<valid>` -> **500**
    - expected due local storage/upstream dependency constraints, while confirming hash gate is no longer the failing check.

### Rollback plan (Phase 13)

1. Revert the four hardened API handlers.
2. Remove `tests/phase13/service-behaviour.test.cjs` if full phase-13 rollback required.
3. Re-run phase6/7/8/9/10/11/12/13 baseline tests + lint after rollback.

## Latest update (2026-03-13 — Phase 14 client-hash signing fix)

- Continued on branch:
    - `TASK22019-phase-9-hardening`
- Fixed authenticated user-journey runtime error during new appeal flow where client-side hashing tried to use server-only `HASHKEY`.
- Added authenticated server-side hash signer endpoint:
    - `pages/api/endpoint/gethash_api.js`
    - requires session (`getSession`), allow-lists supported API paths, returns `{ hash }`.
- Updated direct services to request hash from server signer for browser calls, with server-side fallback only when `HASHKEY` exists:
    - `actions/services/documentDirectService.js`
    - `actions/services/portalDirectService.js`
- Preserved existing API contracts and response shapes in file handlers.
- Added focused tests:
    - `tests/phase14/service-behaviour.test.cjs`
    - covers signer endpoint negative paths + authenticated happy path.

### Validation snapshot (Phase 14)

- `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/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** (4/4)
- `npm run lint` -> **warnings only** (pre-existing hook dependency warnings)

### Rollback plan (Phase 14)

1. Revert `pages/api/endpoint/gethash_api.js`.
2. Revert direct-service hash signer usage in `documentDirectService.js` and `portalDirectService.js`.
3. Remove `tests/phase14/service-behaviour.test.cjs` if rolling back full phase-14 slice.
4. Re-run phase6–phase14 tests + lint.

## Latest update (2026-03-13 — Phase 14 closeout follow-up)

- Continued on branch:
    - `TASK22019-phase-9-hardening`
- Completed follow-up hardening and contract-alignment after runtime verification:
    - `actions/services/accountDirectService.js`
        - `getPortalLogin` now uses authenticated signer endpoint (`/api/endpoint/gethash_api`) for browser-safe hash generation
        - retains server-only fallback to local `hashAPIPath` when `HASHKEY` is available
    - `pages/api/endpoint/gethash_api.js`
        - allow-list expanded for `/api/endpoint/getportallogin_api`
    - `pages/api/file/getrepsblob.js`
        - removed enforced `casefolderID` guard and argument pass-through to align with route contract (`/api/file/getrepsblob?container=...`)
    - `components/elements/index.js`
        - added missing `updateLinks` import from `components/utils` to resolve Quill runtime error
- Tests updated:
    - `tests/phase7/service-behaviour.test.cjs`
        - updated `getPortalLogin` expectations for signer endpoint behavior
    - `tests/phase14/service-behaviour.test.cjs`
        - added allow-list coverage for signer path `/api/endpoint/getportallogin_api`

### Validation snapshot (Phase 14 follow-up)

- `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)
- `npm run lint` -> **warnings only** (pre-existing hook dependency warnings)

### Risks + mitigations (follow-up)

- Risk: signer endpoint over-expansion could broaden hash issuance.
    - Mitigation: strict allow-list retained; only required `getportallogin_api` path added.
- Risk: tightened/changed guards could break existing caller contracts.
    - Mitigation: `getrepsblob` guard aligned back to actual route contract; response shape unchanged.
- Risk: UI runtime dependency regressions during hardening verification.
    - Mitigation: missing `updateLinks` import restored with minimal diff.

### Rollback plan (follow-up)

1. Revert signer-path migration commit `6094874` (or files: `accountDirectService.js`, `gethash_api.js`, `tests/phase7`, `tests/phase14`).
2. Revert contract/import alignment commit `b8fa514` (or files: `getrepsblob.js`, `components/elements/index.js`).
3. Re-run phase6–phase14 tests and lint to confirm rollback parity.

### Rollback plan (Phase 8)

1. Revert the four hardened API handlers.
2. Revert direct-service hash append changes in `documentDirectService` and `portalDirectService`.
3. Remove `tests/phase8/service-behaviour.test.cjs` if full slice rollback required.
4. Re-run phase6/7 baseline tests + lint after rollback.

    - `pages/api/file/createappealcompletemessage_api.js`
    - `pages/api/file/setupcontainer.js`
- Scope delivered:

    - 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)

## Latest update (2026-03-19 — TASK22168 endpoint account contract consistency slice)

- New branch created from `origin/SIPS-Development` with required work item prefix:
    - `TASK22168-endpoint-account-contract-consistency`
- Delivered next coherent low-risk `pages/api/endpoint/**` slice after TASK22109 across:
    - `pages/api/endpoint/getaccounts_api.js`
    - `pages/api/endpoint/getemailaccountcheck_api.js`
    - `pages/api/endpoint/getpreferredlanguage_api.js`
- Scope delivered:
    - removed dead/noisy code in touched handlers (unused imports and commented debug remnants)
    - standardized structured negative-path handling for:
        - missing required `emailAddress`
        - catch/failure paths
    - preserved success response contracts by returning unchanged upstream `data`
- Added focused phase21 endpoint contract coverage:
    - `tests/phase21/endpoint-handler-contract.test.cjs`
    - extended `tests/phase21/api-contract-slice1.test.cjs` runner

### Validation snapshot (TASK22168)

- `node tests/phase21/api-contract-slice1.test.cjs` -> **pass**
    - helper: 4/4
    - file-handler: 11/11
    - email-handler: 12/12
    - endpoint-handler: 7/7
- `npm run lint` -> **warnings only** (pre-existing `react-hooks/exhaustive-deps` warnings)

### Risks + mitigations (TASK22168)

- Risk: endpoint contract drift in success payloads.
    - Mitigation: success responses kept as upstream `data` payload via `respondSuccess`.
- Risk: over-broad behavior change in account/login adjacent APIs.
    - Mitigation: scoped to 3 low-risk handlers only; no auth/session/security flow changes.
- Risk: regression in negative-path status/shape expectations.
    - Mitigation: added explicit phase21 missing-input and catch-path assertions for each touched endpoint.

### Rollback plan (TASK22168)

1. Revert endpoint files:
    - `pages/api/endpoint/getaccounts_api.js`
    - `pages/api/endpoint/getemailaccountcheck_api.js`
    - `pages/api/endpoint/getpreferredlanguage_api.js`
2. Revert phase21 test updates:
    - `tests/phase21/endpoint-handler-contract.test.cjs`
    - `tests/phase21/api-contract-slice1.test.cjs`
3. Re-run:
    - `node tests/phase21/api-contract-slice1.test.cjs`
    - `npm run lint`

## Latest update (2026-03-19 — TASK22168 Bundle C extension on same branch)

- Continued same branch with user-approved larger bundle:
    - `TASK22168-endpoint-account-contract-consistency`
- Added contract-consistency coverage for login/portal/account-adjacent endpoints:
    - `pages/api/endpoint/getlogin_api.js`
    - `pages/api/endpoint/getportallogin_api.js`
    - `pages/api/endpoint/getportalloginproxy_api.js`
    - `pages/api/endpoint/getpersonalaccount_api.js`
- Scope delivered:
    - removed dead imports/commented debug/noisy logging remnants
    - standardized structured 400 errors for required-input negative paths and catch/failure paths
    - preserved success payload contracts via `respondSuccess` pass-through
- Phase21 endpoint suite expanded in:
    - `tests/phase21/endpoint-handler-contract.test.cjs`
    - test count grew from 7 to 18 for endpoint handler coverage

### Validation snapshot (TASK22168 Bundle C)

- `node tests/phase21/api-contract-slice1.test.cjs` -> **pass**
    - helper: 4/4
    - file-handler: 11/11
    - email-handler: 12/12
    - endpoint-handler: 18/18
- `npm run lint` -> **warnings only** (pre-existing `react-hooks/exhaustive-deps` warnings)

### Risks + mitigations (TASK22168 Bundle C)

- Risk: contract drift from broad endpoint touch surface.
    - Mitigation: constrained to login/account adjacency group only and preserved success pass-through behavior.
- Risk: hash-path behavior regression in `getportallogin_api`.
    - Mitigation: explicit tests for missing hash, invalid hash, and catch path.
- Risk: inconsistent required-input behavior across adjacent handlers.
    - Mitigation: standardized explicit required-input envelopes in all four newly touched handlers.

## Latest update (2026-03-13 — myportal + i18n follow-up)

- Branch: `TASK22028-phase15-hardening-slice`
- Delivered follow-up fixes:
    - myportal representation delete calls now use `caseRef` in top-three and view-all flows
    - missing `myportal` namespace added for `/newappeal/[appealtypes]` in `i18n.js`

### Validation snapshot (myportal + i18n follow-up)

- `node tests/phase7/service-behaviour.test.cjs` -> **pass** (12/12)
- `npm run lint` -> **warnings only** (pre-existing)

## Outstanding risks / gaps

- Navigation regressions across EN/CY + route query combinations.
- Drift between rewrite config and component-level locale path logic.
- Deployment ambiguity due to multiple CI/CD artifacts (Azure pipeline, Jenkins, Docker) with unclear active source of truth.
- Security posture variability where hash checks are bypassed/commented in selected handlers.

## Latest update (2026-03-13 — Phase 7 post-Phase-6 hardening)

- New branch created from `origin/SIPS-Development` with required work item prefix:
    - `TASK21988a-phase7-postphase6-hardening`
- Fixed known pre-existing SSR serialization issue on search results route:
    - `pages/searchresults.js`
    - updated SSR dispatch fallback from `setSearch(query.q)` to `setSearch(query?.q || "")`
    - result: `/searchresults` and `/cy/searchresults` now return 200 in local smoke checks (no 500 observed in this run).
- Added expanded behavioural coverage for remaining direct-service domains:
    - new test file: `tests/phase7/service-behaviour.test.cjs`
    - includes document, portal, account, notify, integration behavioural checks
    - includes negative-path assertions for relay/hash/token-sensitive behaviors where feasible:
        - hashed URL append checks (`hashAPIPath`)
        - error handling contracts (undefined/error string/rethrow depending on existing function contract)

### Validation snapshot (Phase 7)

- `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)
- `npm run lint` -> **warnings only** (pre-existing hook dependency warnings; no new lint errors)

### Targeted smoke snapshot (local dev server)

- Note: dev server auto-started on `http://localhost:3001` because port `3000` was in use.
- Search flow:
    - `GET /searchresults` and `GET /cy/searchresults` -> **200**
- Case flow:
    - `GET /case` and `GET /cy/case` -> **200**
- My Portal flow (negative-path):
    - `GET /myportal` and `GET /cy/myportal` -> **307** redirect to `/auth/signin`
- Document flow (negative-path):
    - `GET /api/file/getbloblistproxy?container=test&casefolderID=test` -> **400**
- Notify flow (negative-path):
    - `POST /api/email/notify` with `{}` -> **400**
