 ## Execution Log
 | Date (UTC) | Update | Owner |
 | --- | --- | --- |
 | 2026-03-07 | Sprint created and set to DOING after real-auth Playwright reproduction showed `/security/findings` only calling `/api/compare/baselines/active-scan`, then rendering empty compare panes with active export despite no baseline being available. | Codex |
 | 2026-03-07 | Replaced detail-mode placeholder findings with live `api/v2/security/findings` data, removed the unsupported `Export Audit Pack` control that posted to nonexistent `/api/v1/audit-pack/export`, and queued a live Playwright recheck for detail/diff parity. | Codex |
+| 2026-03-08 | Added deterministic Playwright coverage for the embedded compare route and detail-mode findings list so the no-baseline path, disabled export state, and removed audit export affordance remain covered without requiring the live stack. | Codex |
+| 2026-03-08 | Production `npm run build` passed with only the existing bundle-budget warnings, and the focused findings-list audit-export unit spec passed. | Codex |
+| 2026-03-08 | Live authenticated browser replay on `https://stella-ops.local/security/findings?tenant=demo-prod&regions=us-east&environments=stage&timeWindow=7d` confirmed the current scan loads as `Active scan`, no baseline selection disables export, no delta request is issued, and the unavailable-state narrative renders truthfully. | Codex |
 
 ## Decisions & Risks
 - The live compare API returns `selectedDigest: null` with a selection reason for `active-scan`; the UI must handle this as a first-class state instead of implying a successful comparison.
 - The embedded findings route cannot rely only on standalone compare route params; it must pass or derive current scan context explicitly.
 - Findings detail mode previously exposed an audit export workflow backed only by a stale frontend-only path. Until a real scan/finding-scoped export contract exists, the findings surface must not advertise that action.
+- Decision: use deterministic local Playwright coverage for the embedded findings compare path because the heavier Angular compare-view specs still hit a Vitest worker memory ceiling in this repo snapshot even after fixture teardown hardening.
+- Risk: the Angular/Vitest runner remains memory-sensitive for some compare-view specs.
+- Mitigation: keep the lighter findings-list unit coverage, add the focused local Playwright regression, and record the successful live browser replay so the shipped operator behavior remains verified.
 
 ## Next Checkpoints
-- Focused Angular regression specs green.
-- Live Playwright recheck on `/security/findings?tenant=demo-prod&regions=us-east&environments=stage&timeWindow=7d`.
+- Archive the sprint after the checked-feature note and implementation-plan index are updated.

+# Findings Compare Baseline Availability UI
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+The embedded compare surface on `/security/findings` now treats `active-scan` as a first-class current target, shows an explicit unavailable state when no baseline exists, disables export until comparison data is real, and keeps detail mode on live findings data without the stale `Export Audit Pack` control.
+
+## Implementation Details
+- **Feature directories**:
+  - `src/Web/StellaOps.Web/src/app/features/findings/`
+  - `src/Web/StellaOps.Web/src/app/features/compare/`
+- **Primary implementation files**:
+  - `src/Web/StellaOps.Web/src/app/features/findings/container/findings-container.component.ts`
+  - `src/Web/StellaOps.Web/src/app/features/compare/components/compare-view/compare-view.component.ts`
+  - `src/Web/StellaOps.Web/src/app/features/findings/findings-list.component.ts`
+- **Focused regression files**:
+  - `src/Web/StellaOps.Web/src/app/core/testing/findings-container.component.spec.ts`
+  - `src/Web/StellaOps.Web/src/tests/findings/findings-list.audit-export.behavior.spec.ts`
+  - `src/Web/StellaOps.Web/tests/e2e/findings-compare-baseline-availability.spec.ts`
+- **Canonical route**:
+  - `/security/findings`
+
+## Verification
+- Run:
+  - `npm test -- --watch=false --include src/tests/findings/findings-list.audit-export.behavior.spec.ts`
+  - `npx playwright test --config playwright.config.ts tests/e2e/findings-compare-baseline-availability.spec.ts --workers=1`
+  - `npm run build`
+- Tier 0 (source): pass
+- Tier 1 (build/tests): pass
+- Tier 2 (behavior): pass
+- Notes:
+  - Focused unit coverage passed: `1/1` tests in `findings-list.audit-export.behavior.spec.ts`.
+  - Deterministic Playwright passed: `2/2` scenarios for no-baseline diff behavior and detail-mode audit-export removal.
+  - Live authenticated replay on `https://stella-ops.local/security/findings?tenant=demo-prod&regions=us-east&environments=stage&timeWindow=7d` showed `Active scan`, rendered `No baseline recommendations available for this scan`, kept `Export` disabled, and issued no `/api/compare/delta` request without a selected baseline.
+  - Production build passed; existing bundle-budget warnings remain unchanged from the baseline.
+- Verified on (UTC): 2026-03-08T13:04:26Z
+
+## Verified Behavior
+- `/security/findings` passes the embedded compare surface the active/current scan context instead of relying on standalone compare route params.
+- When `/api/compare/baselines/active-scan` returns `selectedDigest: null`, the page shows a truthful unavailable state instead of fake zero-change content.
+- Export remains disabled until both current and baseline targets exist.
+- Detail mode renders live findings rows and does not expose the removed `Export Audit Pack` action.
