CL-002: Priority 1 Refactor (Phase 1) — actions/index.js split foundation

date: 2026-03-12
author: Cline
scope: actions/index.js, actions/core/*, actions/services/legacyActionsService.js, actions/clients/README.md, memory-bank/*
type: change
rationale: Reduce coupling in the actions monolith by extracting core helpers while keeping backward-compatible exports for existing consumers.
impact: Lower regression blast radius for future actions-related changes; no intended functional behavior change.
status: completed

Summary: Extracted helper concerns from actions/index.js into focused actions/core modules (env, logger, hash, token, headers). Replaced actions/index.js with a compatibility barrel and moved operational wrappers into actions/services/legacyActionsService.js with imports from core helpers.

Validation:

• Branch created: 0000-update-actions-monolith.
• Compatibility preserved by re-exporting legacy service functions plus core exports from actions/index.js.
• Lint run for regression check.

Follow-ups:

• Phase 2: split legacyActionsService by domain into dedicated service/client modules.
• Add helper-focused automated tests for core modules and export parity checks.

---

CL-003: Priority 1 Refactor (Phase 2) — service grouping via compatibility layer

date: 2026-03-12
author: Cline
scope: actions/services/*, actions/index.js, memory-bank/*
type: change
rationale: Continue reducing monolith risk by introducing domain service boundaries while preserving public action exports.
impact: Maintains backward compatibility for existing ../actions imports; improves maintainability and safer future migration to targeted imports.
status: completed

Summary: Added grouped service modules (searchService, caseService, accountService, portalService, documentService, referenceDataService, notifyService, adminService, integrationService) plus actions/services/index.js barrel. Updated actions/index.js to export from ./services (and core modules), keeping legacy function names/signatures available.

Validation:

• Service export coverage check confirms all legacy exports are represented in grouped services.
• npm run lint still fails due legacy Next/ESLint option incompatibility (tooling issue, unchanged by this refactor).

Follow-ups:

• Incrementally migrate high-churn consumers to direct service imports.
• Add automated export-parity and helper unit tests.

---

CL-004: Priority 1 Refactor (Phase 3) — targeted consumer import migration

date: 2026-03-12
author: Cline
scope: components/case/summary.js, pages/api/email/notify.js, selected pages/api/endpoint/*, memory-bank/*
type: change
rationale: Begin replacing broad actions barrel imports with focused service/core module imports in high-churn and representative endpoint areas.
impact: Lower coupling to monolithic action entrypoint while preserving behavior and public compatibility.
status: completed

Summary: Migrated targeted consumers to direct imports from actions/services/* and actions/core/* without changing function signatures or route contracts.

Validation:

• Lint still blocked by repository ESLint/Next option compatibility issue (pre-existing tooling configuration).
• Manual testing remains required for search/case/myportal/auth/notify/file matrix.

Follow-ups:

• Continue phased import migration for additional pages/api/endpoint/** handlers.
• Add export-parity and helper-level tests as planned.

---

CL-005: Priority 1 Refactor (Phase 4) — helper hardening + redacted logging baseline

date: 2026-03-12
author: Cline
scope: actions/core/{guards,logger}.js, actions/index.js, selected API handlers
type: change
rationale: Introduce low-risk guard and redaction primitives, then apply them to sensitive/high-churn API paths to reduce injection/privacy risk while preserving behavior.
impact: Better input hygiene and safer diagnostics in selected notify/login/contact flows; no intended contract changes.
status: completed

Summary: Added guards helper module (isNonEmptyString, sanitizeString, escapeODataString) and logger redaction utility (redactSensitive). Adopted these helpers in notify, getpreferredlanguage_api, and createcrmtask_api handlers.

Validation:

• npm run lint remains blocked by existing Next/ESLint options incompatibility in repository tooling.
• Targeted diff review confirms changes are scoped to helper hardening and selected handlers.

Follow-ups:

• Continue Phase 4 adoption for additional sensitive file/email/auth handlers.
• Add focused unit tests for guards and redactSensitive behavior.

CL-006: Priority 1 Refactor — consumer migration pass (portal/form/admin utilities)

date: 2026-03-12
author: Cline
scope: components/admin/*, components/case/*, components/myportal/*, components/elements/index.js, components/utils/index.js, lib/*, memory-bank/*
type: change
rationale: Continue Phase 3-style decoupling by replacing broad actions barrel imports with focused service/core imports in high-use consumer files while preserving behavior.
impact: Lower coupling to monolithic action barrel and clearer dependency boundaries; no intended functional behavior change.
status: completed

Summary: Migrated a targeted set of portal/form/admin utility consumers from ../../actions/../../../actions to explicit imports from actions/services/* and actions/core/*. Also resolved migration-side compile issues in components/myportal/topthree_reps.js (duplicate import source and invalid res.status usage in client context).

Validation:

• In-scope consumer files now have no broad from "../../actions" / from "../../../actions" imports.
• npm run lint re-run; result unchanged and blocked by pre-existing Next/ESLint option incompatibility.

Follow-ups:

• Continue migrating remaining broad actions imports in components/myportal/viewall.js, components/search/addresssearchresults.js, unsubscribe flows, and selected API endpoints.
• Add focused manual smoke checks for myportal representations and awaiting-submission deletion/edit flows after this import migration.

author: Cline
scope: components/myportal/viewall.js, components/search/addresssearchresults.js, pages/unsubscribe/[watchlistid].js, pages/unsubscribeall/[watchlistid].js, memory-bank/*
type: change
rationale: Continue Phase 3 decoupling by removing additional broad actions barrel imports in high-use myportal/search/unsubscribe flows and replacing them with focused service/core imports.
impact: Reduced coupling to monolithic action barrel with intended behavior parity; no API contract changes intended.
status: completed

Summary: Migrated four additional consumers away from ../../actions:

• components/myportal/viewall.js -> actions/services/documentService, actions/services/portalService, actions/core/logger
• components/search/addresssearchresults.js -> actions/services/portalService
• pages/unsubscribe/[watchlistid].js -> actions/core/{hash,token,headers,logger}
• pages/unsubscribeall/[watchlistid].js -> actions/core/{hash,token,headers,logger}

Validation:

• Regex verification confirms these four files no longer import from the broad actions barrel.
• Repository-wide broad-import scan now reports 11 matches total, including comment-only occurrences and remaining endpoint/file handlers pending migration.

Follow-ups:

• Migrate remaining non-comment broad imports in selected pages/api/endpoint/* and pages/api/file/* handlers.
• Run focused manual smoke checks for myportal view-all watch/unwatch + unsubscribe routes (EN/CY path sanity and negative paths).

date: 2026-03-12
author: Cline
scope: pages/api/endpoint/*, pages/api/file/* (selected handlers), memory-bank/*
type: change
rationale: Continue Phase 3 migration by replacing broad actions barrel imports in selected endpoint/file proxy handlers with focused actions/core/* and service module imports.
impact: Further reduces monolithic import coupling in API paths while preserving existing request/response behavior and hash/token/header patterns.
status: completed

Summary: Migrated these handlers away from broad ../../../actions imports:

• pages/api/endpoint/getmylpacases_api.js
  • getLPA -> actions/services/referenceDataService
  • azureHeaders, consoleLogger, getToken, hashAPIPath -> actions/core/*
  • removed local duplicated hashAPIPath implementation

• pages/api/file/getrepsblobproxy.js
• pages/api/file/getbloblistproxy.js
• pages/api/file/createappealcompletemessageproxy_api.js

Validation:

• Regex scans over pages/api/endpoint and pages/api/file show 0 remaining broad from "../../../actions" imports.
• git status --short confirms this chunk is isolated to the targeted endpoint/file handlers.

Follow-ups:

• Run focused manual smoke checks for touched endpoint/file flows (paged search APIs, LPA case retrieval, blob proxy endpoints).
• Continue hardening pass for sensitive handlers with guard/redaction helpers where not yet applied.

  • invalid/missing hash for all 4 handlers -> 400
  • missing required key params where tested -> 400
  • valid-hash spot-check (getportallogin_api) still returned 400 due upstream relay/CRM behavior in local env (hash gate passed, downstream dependency failed)

Follow-ups:

• Investigate local relay/CRM dependency behavior for getportallogin_api happy path in integrated environment.
• Continue incremental hash/negative-path hardening for other sensitive pages/api/file/** handlers still carrying commented bypass patterns.

Rollback plan:

• Removed legacy commented debug traces in touched handlers.
• Added focused phase-11 tests:
  • tests/phase11/service-behaviour.test.cjs
  • includes negative-path coverage and one valid-hash mocked happy path.

Validation:

• node tests/phase6/service-parity.test.cjs -> pass

• Manual HTTP checks (localhost:3000):
  • missing/invalid hash for selected phase-11 handlers -> 400
  • valid-hash getbloblist spot-check -> 500 due local downstream/storage dependency constraints

Follow-ups:

• Continue next incremental slice for remaining sensitive handlers with commented/bypassed hash checks.

Rollback plan:

• Revert the 3 hardened API handlers.
• Remove tests/phase11/service-behaviour.test.cjs if rolling back full phase-11 slice.
• Re-run phase6/7/8/9/10/11 tests + lint to confirm rollback parity.

CL-024: Phase 14 fix — authenticated server-side hash signing for browser callers

date: 2026-03-13 author: Cline scope: actions/services/{documentDirectService,portalDirectService}.js, pages/api/endpoint/gethash_api.js, tests/phase14/service-behaviour.test.cjs, memory-bank/* type: change rationale: Fix runtime break in authenticated new-appeal journey where client-side hash generation attempted to use server-only HASHKEY. impact: Restores browser flow while preserving hash-guard posture by moving hash generation to authenticated server endpoint; no intended external API contract changes. status: completed

Summary:

• Added gethash_api endpoint to sign allow-listed API paths server-side.
• Endpoint enforces authenticated session and rejects unsupported paths.
• Updated direct services to fetch hash from signer endpoint for browser calls.
• Added server-side fallback hashing only when HASHKEY exists (non-browser contexts).
• Added phase-14 tests for missing-path, invalid-path, unauthenticated, and happy-path signer behavior.

Validation:

• node tests/phase6/service-parity.test.cjs -> pass
• node tests/phase6/service-behaviour.test.cjs -> pass
• node tests/phase7/service-behaviour.test.cjs -> pass
• node tests/phase8/service-behaviour.test.cjs -> pass

• node tests/phase13/service-behaviour.test.cjs -> pass
• node tests/phase14/service-behaviour.test.cjs -> pass (4/4)
• npm run lint -> warnings only (pre-existing warnings)

Follow-ups:

• Keep signer allow-list tight and expand only for explicitly required browser-side hash use cases.
• Continue removing legacy client-side direct hash assumptions as encountered.

CL-025: Phase 14 closeout follow-up — portal-login signer adoption + contract alignment fixes

date: 2026-03-13 author: Cline scope: actions/services/accountDirectService.js, pages/api/endpoint/gethash_api.js, tests/phase7/service-behaviour.test.cjs, tests/phase14/service-behaviour.test.cjs, pages/api/file/getrepsblob.js, components/elements/index.js, memory-bank/* type: change rationale: Extend browser-safe hash signing to portal-login call path, keep signer allow-list explicit, and align an over-tightened file guard with actual endpoint contract discovered during runtime verification. impact: Removes remaining browser-side hash risk in portal login path; preserves API response contracts while restoring route-accurate parameter validation and resolving Quill runtime import issue. status: completed

Summary:

• Updated accountDirectService.getPortalLogin to use /api/endpoint/gethash_api for signed hash retrieval in browser contexts.
• Added /api/endpoint/getportallogin_api to signer endpoint allow-list in gethash_api.js.
• Updated tests to reflect signer-driven behavior and allow-list coverage:
  • tests/phase7/service-behaviour.test.cjs
  • tests/phase14/service-behaviour.test.cjs
• Applied follow-up runtime/contract fixes confirmed during manual verification:
  • pages/api/file/getrepsblob.js: removed casefolderID hard requirement and pass-through argument to align with route usage (container + hash).
  • components/elements/index.js: restored missing updateLinks import required by Quill-related flow.
• Branch pushed with follow-up commits:
  • 6094874
  • b8fa514

Validation:

• node tests/phase6/service-parity.test.cjs -> pass
• node tests/phase6/service-behaviour.test.cjs -> pass
• 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)

Follow-ups:

• Keep signer allow-list expansion minimal and task-driven.
• Continue replacing remaining browser-side direct hash assumptions only where flows require it.
• Confirm work-item/branch naming alignment for any subsequent phase slices if strict tracker continuity is required.

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.
