+# Sprint 20260220-016 - FE Pack 19 Exceptions Conformity Gap
+
+## Topic & Scope
+- Close the remaining pack conformity gap after full `pack-01..pack-21` Playwright verification.
+- Implement Pack 19 Exceptions screen semantics at canonical `Security & Risk` routes.
+- Preserve existing triage workflows while separating them from the Pack 19 Exceptions surface.
+- Working directory: `src/Web/StellaOps.Web`.
+- Expected evidence: focused unit tests, Playwright pack-conformance pass, and updated diff ledger.
+
+## Dependencies & Concurrency
+- Depends on current canonical route map in `src/Web/StellaOps.Web/src/app/routes/security-risk.routes.ts`.
+- Depends on Pack source-of-truth docs in `docs/modules/ui/v2-rewire/pack-19.md` and `docs/modules/ui/v2-rewire/source-of-truth.md`.
+- Safe concurrency: may run in parallel with non-security FE work if no edits touch `security-risk` routes/components.
+
+## Documentation Prerequisites
+- `docs/modules/ui/v2-rewire/pack-19.md`
+- `docs/modules/ui/v2-rewire/source-of-truth.md`
+- `docs/modules/ui/v2-rewire/pack-conformity-diff-2026-02-20.md`
+
+## Delivery Tracker
+
+### S19-EX-01 - Replace Pack 19 Exceptions route surface
+Status: TODO
+Dependency: none
+Owners: FE implementer
+Task description:
+- Replace `/security-risk/exceptions` route target so it renders a dedicated Exceptions screen aligned to Pack 19 section 19.10.
+- Keep route canonical and maintain existing breadcrumb/title behavior under `Security & Risk`.
+
+Completion criteria:
+- [ ] `/security-risk/exceptions` no longer resolves to triage artifact UI.
+- [ ] Exceptions list UI vocabulary reflects waiver/risk acceptance domain.
+- [ ] Sidebar navigation label/path behavior remains stable for `Security & Risk`.
+
+### S19-EX-02 - Add Exception detail workflow route
+Status: TODO
+Dependency: S19-EX-01
+Owners: FE implementer
+Task description:
+- Implement dedicated Exception detail surface for `/security-risk/exceptions/:id`.
+- Ensure drill-down links from Exceptions list use this route and preserve back navigation to Exceptions list.
+
+Completion criteria:
+- [ ] `/security-risk/exceptions/:id` resolves to an Exception detail view, not triage artifact detail.
+- [ ] Exceptions list has deterministic navigation to detail.
+- [ ] Detail view includes status, scope, expiry, approvals, and evidence pointers required by Pack 19 intent.
+
+### S19-EX-03 - Test coverage and pack-conformance verification
+Status: TODO
+Dependency: S19-EX-01
+Owners: FE implementer, QA
+Task description:
+- Add or update unit tests for the new Exceptions route wiring and core rendering assertions.
+- Re-run pack-conformance Playwright sweep against `pack-01..pack-21` and ensure zero mismatches.
+
+Completion criteria:
+- [ ] Unit tests pass for new Exceptions route/component behavior.
+- [ ] `tests/e2e/pack-conformance.scratch.spec.ts` passes with no mismatches.
+- [ ] Test commands and outputs recorded in this sprint `Execution Log`.
+
+### S19-EX-04 - Update pack difference ledger and close sprint
+Status: TODO
+Dependency: S19-EX-03
+Owners: FE implementer, Documentation author
+Task description:
+- Update `docs/modules/ui/v2-rewire/pack-conformity-diff-2026-02-20.md` from `DIFF` to resolved state when implementation lands.
+- Archive this sprint only after all tasks are `DONE`.
+
+Completion criteria:
+- [ ] Pack diff ledger updated to reflect resolved Pack 19 mismatch.
+- [ ] All tasks in this sprint are `DONE`.
+- [ ] Sprint moved to `docs-archived/implplan/` only after criteria are met.
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2026-02-20 | Sprint created from full Pack conformity run. Result: 61 checks, 1 mismatch at Pack 19 Exceptions route. | Planning |
+| 2026-02-20 | Reproduced mismatch with filtered run (`PACK_CONFORMANCE_FILTER='pack-19.*exceptions'`) to isolate route-level nonconformance. | QA |
+
+## Decisions & Risks
+- Decision: treat latest pack precedence as authoritative; Pack 19 section 19.10 governs Exceptions behavior.
+- Decision: keep this sprint FE-scoped with route/component separation first; backend enrichment can layer without blocking route conformance.
+- Risk: replacing current route target can break users relying on triage page at `/security-risk/exceptions`; mitigate by preserving triage under existing triage paths and adding redirects if needed.
+- Risk: pack-conformance run is sensitive to dev proxy path capture for `/integrations` and `/platform`; mitigate by using clean proxy config during conformity runs.
+- Evidence reference: `docs/modules/ui/v2-rewire/pack-conformity-diff-2026-02-20.md`.
+
+## Next Checkpoints
+- 2026-02-21: route/component implementation complete and unit tests green.
+- 2026-02-21: full Playwright pack-conformance rerun shows zero mismatches.
+- 2026-02-21: sprint ready for archive review.
