Keep replay-share redaction helper-owned and treat copied URLs as redacted local artifacts, not public-safe or hosted replay links. 2. Keep scan-root failures compact in broad UI and route errors. The UI can mention the allowlist rule and `FACTIONOS_SCAN_ROOTS`, but must not echo unapproved absolute roots from server failures. 3. Keep export UX tied to the local server, local auth header helper, schema headers, privacy headers, no-store behavior, and bounded failure messages. 4. Keep browser notifications opt-in and local-only. The UI must not imply push backend delivery. 5. Keep reset work scoped to settings, seed data, and replay controls. Unified erasure remains Phase 08 release hardening. *** ## Validation Plan * Run focused web tests for settings store, scan helper/UI, notifications, replay share, export helper, and privacy boundaries. * Run focused server tests for LLM scan route and export route privacy envelopes. * Run focused Biome checks on touched app, server, test, and doc files. * Run `git diff --check`. * Run ASCII validation for spec-system output files and LF validation for touched text outputs. *** ## Deferred-Erasure Risk Log * Unified erasure across archives, memory, browser settings, replay buffers, PID/workspace files, and server session state is still deferred to Phase 08. * Session 06 reset controls must clearly reset only current in-browser preferences or seeded UI state. * Docs must continue to state that redacted archives, replay buffers, settings, and memory findings remain local retention surfaces until trusted erasure ships. *** ## Task Log ### Task T001 - Verify prerequisites, Session 06 rows, and current coverage **Started**: 2026-05-29 09:33 IDT **Completed**: 2026-05-29 09:35 IDT **Duration**: 2 minutes **Notes**: * Confirmed Sessions 01-05 are completed in `.spec_system/state.json`. * Read the Session 06 PRD stub and the Phase 02 product surface gap matrix rows for settings preferences, browser notifications, replay share links, session export, and scan-root UX. * Reviewed existing coverage in web tests for settings storage, scan UI, notifications, replay links/share, export helper, WebSocket privacy, and server tests for LLM scan/export routes. * Confirmed implementation scope is cross-cutting and package context remains null. **Files Changed**: * `.spec_system/specs/phase02-session06-settings-replay-notifications-and-scan-ux/implementation-notes.md` - captured baseline evidence and T001 log. *** ### Task T002 - Create implementation notes **Started**: 2026-05-29 09:35 IDT **Completed**: 2026-05-29 09:36 IDT **Duration**: 1 minute **Notes**: * Created the session implementation notes file with baseline commands, privacy-boundary decisions, validation plan, and deferred-erasure risk log. * Captured the current dirty worktree observation without reverting pre-existing state changes. **Files Changed**: * `.spec_system/specs/phase02-session06-settings-replay-notifications-and-scan-ux/implementation-notes.md` - initialized the required implementation evidence log. *** ### Task T003 - Audit stable docs before implementation **Started**: 2026-05-29 09:35 IDT **Completed**: 2026-05-29 09:37 IDT **Duration**: 2 minutes **Notes**: * Reviewed `apps/web/README_web.md`, `apps/server/README_server.md`, `docs/api/README_api.md`, `docs/privacy-and-security.md`, and `docs/development.md`. * Current server/API/privacy docs already mention scan-root allowlists, local LLM fallback, export privacy headers, redacted archives, and local retention risk. * Web README lacks a specific settings/replay/notifications/export/scan section, and stable docs need Session 06 UX language for browser localStorage recovery, local-only notification delivery, replay-share copy, export feedback, and Phase 08 erasure deferral. **Files Changed**: * `.spec_system/specs/phase02-session06-settings-replay-notifications-and-scan-ux/implementation-notes.md` - captured doc audit findings before code changes. *** ### Task T004 - Create scan-codebase UI helpers **Started**: 2026-05-29 09:37 IDT **Completed**: 2026-05-29 09:38 IDT **Duration**: 1 minute **Notes**: * Added helper-owned scan-root normalization, request construction, response summary parsing, header reporting, and compact failure mapping. * Mapped empty root, filesystem-root, unapproved root, invalid directory, server offline, HTTP, and unreadable response paths without echoing absolute roots. * Preserved local auth headers through the scan request helper. **Files Changed**: * `apps/web/src/lib/scanCodebase.ts` - created testable scan request, response, sanitization, and failure-copy helpers. **BQC Fixes**: * Trust boundary enforcement: scan response bodies and failure details are schema-checked before UI summary use (`apps/web/src/lib/scanCodebase.ts`). * Failure path completeness: offline, bad response, invalid root, denied root, and filesystem-root outcomes return explicit user-visible failures (`apps/web/src/lib/scanCodebase.ts`). * Error information boundaries: broad scan failure copy sanitizes paths, URLs, bearer values, and token-like fragments (`apps/web/src/lib/scanCodebase.ts`). *** ### Task T005 - Harden settings localStorage hydration **Started**: 2026-05-29 09:38 IDT **Completed**: 2026-05-29 09:39 IDT **Duration**: 1 minute **Notes**: * Added persisted snapshot normalization for malformed, non-object, partial, stale, and invalid enum values. * Normalized severity filters by known keys only, preserving defaults for missing or non-boolean entries. * Reset now writes a fresh default snapshot rather than sharing mutable nested default state. * Storage read/write failures still degrade to defaults and do not crash app import or settings updates. **Files Changed**: * `apps/web/src/store/useSettingsStore.ts` - added normalization helpers, cloned defaults, stricter enum checks, and safer reset persistence. **BQC Fixes**: * State freshness on re-entry: settings hydration and reset now revalidate persisted values into a fresh bounded snapshot (`apps/web/src/store/useSettingsStore.ts`). * Failure path completeness: unavailable or throwing storage falls back to cloned defaults without impossible state (`apps/web/src/store/useSettingsStore.ts`). * Contract alignment: persisted severity and enum fields now match declared TypeScript unions before entering store state (`apps/web/src/store/useSettingsStore.ts`). *** ### Task T006 - Normalize notification outcome helpers **Started**: 2026-05-29 09:39 IDT **Completed**: 2026-05-29 09:40 IDT **Duration**: 1 minute **Notes**: * Exported notification result typing and added copy helpers for permission status and notification fire results. * Covered unsupported, default, denied, granted, local-blocked, revoked, throttled, delivered, and constructor-failure outcomes. * Added a helper for whether the test notification action is eligible. **Files Changed**: * `apps/web/src/lib/notifications.ts` - added normalized notification copy, outcome, and eligibility helpers. **BQC Fixes**: * Failure path completeness: every notification suppression reason now maps to visible local copy (`apps/web/src/lib/notifications.ts`). * Contract alignment: notification UI outcomes are derived from the same `NotifyResult` and permission union used by delivery helpers (`apps/web/src/lib/notifications.ts`). *** ### Task T007 - Tighten replay-link helper outcomes **Started**: 2026-05-29 09:40 IDT **Completed**: 2026-05-29 09:42 IDT **Duration**: 2 minutes **Notes**: * Added detailed replay hash inspection while keeping the existing `readReplayHash` null-return contract. * Added local-only share success/failure copy helpers for redacted URL-fragment replay links. * Updated boot replay handling to strip malformed replay hashes, warn visibly, and avoid repeated replay attempts. * Preserved existing event caps, per-event size rejection, redaction, and replaying flag feedback-loop guard. **Files Changed**: * `apps/web/src/lib/replayLink.ts` - added detailed hash inspection, share-copy helpers, and malformed boot-hash feedback. **BQC Fixes**: * Failure path completeness: malformed and empty replay hashes now produce explicit user feedback at boot (`apps/web/src/lib/replayLink.ts`). * State freshness on re-entry: malformed replay hashes are stripped before returning so refreshes do not repeat the same invalid attempt (`apps/web/src/lib/replayLink.ts`). * Error information boundaries: share copy states that replay links are redacted local URL fragments without implying hosted/public safety (`apps/web/src/lib/replayLink.ts`). *** ### Task T008 - Bound export helper failure copy **Started**: 2026-05-29 09:42 IDT **Completed**: 2026-05-29 09:43 IDT **Duration**: 1 minute **Notes**: * Added a timeout-backed fetch path for local session exports. * Mapped network failures to local-server dependency copy instead of raw exception strings. * Sanitized HTTP, blob-read, and browser-download failures for paths, URLs, bearer values, and token-like fragments. * Kept schema/privacy header reporting in success toasts and made local-server provenance explicit. **Files Changed**: * `apps/web/src/lib/exportSession.ts` - added timeout handling, sanitized failure mapping, and stronger success copy. **BQC Fixes**: * External dependency resilience: export requests now have a bounded timeout and offline failure path (`apps/web/src/lib/exportSession.ts`). * Failure path completeness: fetch, HTTP, blob, and browser download failures map to caller-visible failures (`apps/web/src/lib/exportSession.ts`). * Error information boundaries: export failure copy sanitizes sensitive values before toasts (`apps/web/src/lib/exportSession.ts`). *** ### Task T009 - Wire SettingsDrawer preference controls and reset feedback **Started**: 2026-05-29 09:43 IDT **Completed**: 2026-05-29 09:45 IDT **Duration**: 2 minutes **Notes**: * Added drawer focus on open and kept Escape/click-outside dismissal. * Added accessible labels for severity toggle actions. * Added visible reset feedback for seed-data and settings reset actions. * Kept replay entry through the existing controlled replay panel state. * Added local auth affordance copy for scan/export requests without exposing token values. **Files Changed**: * `apps/web/src/components/SettingsDrawer.tsx` - wired reset toasts, focus management, severity labels, replay entry preservation, and local auth copy. **BQC Fixes**: * Accessibility and platform compliance: drawer receives focus on open and controls expose clearer accessible names (`apps/web/src/components/SettingsDrawer.tsx`). * Error information boundaries: local auth UI mentions header behavior without rendering token values (`apps/web/src/components/SettingsDrawer.tsx`). *** ### Task T010 - Wire SettingsDrawer scan UX through helpers **Started**: 2026-05-29 09:43 IDT **Completed**: 2026-05-29 09:45 IDT **Duration**: 2 minutes **Notes**: * Replaced inline scan fetch and error handling with `runCodebaseScan`. * Scan toasts no longer echo the requested absolute root path. * Added visible error summary copy for empty root, invalid root, denied root, filesystem-root, offline, and compact HTTP failures. * Preserved duplicate-trigger prevention by disabling the action while scanning. * Success copy surfaces issue count, file count, privacy, and provider-transfer headers when present. **Files Changed**: * `apps/web/src/components/SettingsDrawer.tsx` - wired scan UI to helper-owned request, response, and error copy. **BQC Fixes**: * Duplicate action prevention: scan action remains disabled while a scan is in-flight (`apps/web/src/components/SettingsDrawer.tsx`). * Failure path completeness: scan failures render a visible summary and toast for each helper outcome (`apps/web/src/components/SettingsDrawer.tsx`). * Error information boundaries: broad scan toasts and summaries avoid displaying raw absolute roots (`apps/web/src/components/SettingsDrawer.tsx`). *** ### Task T011 - Wire SettingsDrawer notification feedback **Started**: 2026-05-29 09:43 IDT **Completed**: 2026-05-29 09:45 IDT **Duration**: 2 minutes **Notes**: * Reused normalized notification copy helpers for the toggle, permission status, and test action. * Added a busy guard around the permission request path so repeated toggle clicks cannot spawn overlapping permission flows. * Test notification feedback now distinguishes delivered, unsupported, default, denied, throttled, and constructor-failure outcomes. * Permission status refreshes when the drawer opens or settings change. **Files Changed**: * `apps/web/src/components/SettingsDrawer.tsx` - wired notification state/copy helpers and permission-request guard. **BQC Fixes**: * Duplicate action prevention: permission request handling ignores duplicate toggle work while busy (`apps/web/src/components/SettingsDrawer.tsx`). * State freshness on re-entry: drawer refreshes browser permission state on open and after notification tests (`apps/web/src/components/SettingsDrawer.tsx`). * Failure path completeness: all notification helper outcomes route to visible toasts/status text (`apps/web/src/components/SettingsDrawer.tsx`). *** ### Task T012 - Update ReplayPanel status and share feedback **Started**: 2026-05-29 09:45 IDT **Completed**: 2026-05-29 09:46 IDT **Duration**: 1 minute **Notes**: * Added visible local-only replay-share copy. * Added a sharing guard and disabled state while clipboard work is in-flight. * Reused replay share copy helpers for empty windows, encode failures, copied links, and clipboard fallback. * Added clear-buffer feedback and reset transient share state when the panel opens or clears. **Files Changed**: * `apps/web/src/components/ReplayPanel.tsx` - wired replay share copy helpers, in-flight guard, clear feedback, and local-only status copy. **BQC Fixes**: * Duplicate action prevention: share action is disabled while clipboard/export of the URL is in-flight (`apps/web/src/components/ReplayPanel.tsx`). * State freshness on re-entry: transient share state resets when the panel opens and when the buffer is cleared (`apps/web/src/components/ReplayPanel.tsx`). * Error information boundaries: share copy describes redacted URL fragments without public-hosted claims (`apps/web/src/components/ReplayPanel.tsx`). *** ### Task T013 - Preserve share-replay boot feedback and malformed handling **Started**: 2026-05-29 09:40 IDT **Completed**: 2026-05-29 09:46 IDT **Duration**: 6 minutes **Notes**: * Boot-time replay now distinguishes absent hashes from malformed or empty replay hashes. * Malformed replay hashes are stripped before returning, preventing repeated refresh attempts. * Valid replay boot copy states redacted local events and retains the replaying flag guard that prevents capture feedback loops. * Existing event cap and per-event payload cap behavior remains unchanged. **Files Changed**: * `apps/web/src/lib/replayLink.ts` - added detailed hash inspection and malformed boot-hash feedback while preserving caps and redaction. **BQC Fixes**: * State freshness on re-entry: consumed malformed replay hashes are stripped from the URL (`apps/web/src/lib/replayLink.ts`). * Failure path completeness: invalid replay links produce warning toasts instead of silent no-ops (`apps/web/src/lib/replayLink.ts`). * Contract alignment: boot replay still drives events through the declared `ServerEvent` sink and replaying flag contract (`apps/web/src/lib/replayLink.ts`). *** ### Task T014 - Keep export commands honest **Started**: 2026-05-29 09:46 IDT **Completed**: 2026-05-29 09:47 IDT **Duration**: 1 minute **Notes**: * Added command-palette export in-flight tracking with duplicate-start feedback. * Export commands now use the hardened helper path that includes local-server dependency copy, local auth headers, privacy/schema headers, and bounded failures. * Palette footer shows an in-flight export indicator when the palette is open during a running export. **Files Changed**: * `apps/web/src/components/CommandPalette.tsx` - added export in-flight guard and routed export commands through the guarded runner. **BQC Fixes**: * Duplicate action prevention: repeated CSV/JSON export commands are rejected while an export is already running (`apps/web/src/components/CommandPalette.tsx`). * Failure path completeness: command-triggered exports route through bounded helper failures and toasts (`apps/web/src/components/CommandPalette.tsx`). *** ### Task T015 - Verify scan-root and export route envelopes **Started**: 2026-05-29 09:47 IDT **Completed**: 2026-05-29 09:48 IDT **Duration**: 1 minute **Notes**: * Added server route tests for non-directory scan roots, malformed scan bodies, and invalid export body format values. * Locked in compact validation envelopes that do not echo raw invalid roots, token-like strings, or raw invalid export format values. * Existing filesystem-root, unapproved-root, malformed scan option, privacy header, invalid query format, and malformed JSON body tests remain in place. **Files Changed**: * `apps/server/tests/llm.test.ts` - added scan-root privacy envelope coverage. * `apps/server/tests/exportRoute.test.ts` - added invalid body format privacy envelope coverage. **BQC Fixes**: * Error information boundaries: tests now assert scan/export validation envelopes avoid sensitive raw input echoes (`apps/server/tests/llm.test.ts`, `apps/server/tests/exportRoute.test.ts`). * Trust boundary enforcement: malformed scan and export inputs are locked to compact validation responses (`apps/server/tests/llm.test.ts`, `apps/server/tests/exportRoute.test.ts`). *** ### Task T016 - Update package READMEs **Started**: 2026-05-29 09:48 IDT **Completed**: 2026-05-29 09:50 IDT **Duration**: 2 minutes **Notes**: * Added a web README contract for settings persistence, reset scope, local notifications, replay share links, exports, and scan-root UX. * Updated server README scan and export sections to state compact failure envelopes and no raw requested-root or invalid-format echo. * Reconfirmed hosted replay, push backend, hosted accounts, analytics, and unified erasure remain deferred. **Files Changed**: * `apps/web/README_web.md` - documented shipped Session 06 web UX contract and Phase 08 erasure deferral. * `apps/server/README_server.md` - documented scan/export failure envelope privacy boundaries. *** ### Task T017 - Update stable API, privacy, and development docs **Started**: 2026-05-29 09:49 IDT **Completed**: 2026-05-29 09:50 IDT **Duration**: 1 minute **Notes**: * Updated API docs for scan-root refusal cases, symlink/generated-artifact behavior, file/content caps, provider-transfer headers, export headers, and compact invalid-format envelopes. * Updated privacy docs for replay hash stripping, settings localStorage normalization, notification fallback states, and local-only no-push behavior. * Updated development docs with concrete localStorage keys, scan-root behavior, and notification development guidance. **Files Changed**: * `docs/api/README_api.md` - refreshed scan/export API privacy behavior. * `docs/privacy-and-security.md` - refreshed settings, replay, and notification posture. * `docs/development.md` - refreshed localStorage, scan-root, and notification development notes. *** ### Task T018 - Add settings and scan tests **Started**: 2026-05-29 09:50 IDT **Completed**: 2026-05-29 09:52 IDT **Duration**: 2 minutes **Notes**: * Added scan helper tests for empty root, request body, success summaries, approved-root failures, offline mapping, and sanitization. * Updated SettingsDrawer scan tests for redacted approved-root summaries and bounded offline copy. * Added settings store tests for stale partial snapshots, invalid enum fallback, ignored unknown severity keys, malformed notification values, and throwing storage reads. **Files Changed**: * `apps/web/tests/scanCodebase.test.ts` - added focused scan helper tests. * `apps/web/tests/SettingsScan.test.tsx` - updated scan UI assertions for redacted copy. * `apps/web/tests/useSettingsStore.test.ts` - added malformed/stale/storage-unavailable coverage. *** ### Task T019 - Extend notification tests **Started**: 2026-05-29 09:52 IDT **Completed**: 2026-05-29 09:52 IDT **Duration**: 1 minute **Notes**: * Added notification copy helper coverage for unsupported, default, denied/revoked, granted, local-blocked, delivered, throttled, constructor-failure, and test eligibility states. * Existing settings notification persistence and `useNotifications` baseline/no-retroactive-delivery tests remain in place. **Files Changed**: * `apps/web/tests/notifications.test.ts` - added normalized notification outcome helper tests. *** ### Task T020 - Extend replay/export privacy tests **Started**: 2026-05-29 09:52 IDT **Completed**: 2026-05-29 09:52 IDT **Duration**: 1 minute **Notes**: * Added replay hash inspection tests for absent, malformed, empty, and valid hashes plus local redacted share copy. * Added boot malformed-hash coverage to prove hash stripping, warning feedback, and no event dispatch. * Updated export tests for bounded offline copy, timeout mapping, sanitized failure text, and local-server success copy. **Files Changed**: * `apps/web/tests/replayLink.test.ts` - added detailed replay hash and malformed boot tests. * `apps/web/tests/exportSession.test.ts` - added timeout/sanitization tests and updated offline copy expectations. *** ### Task T021 - Run focused tests and quality gates **Started**: 2026-05-29 09:53 IDT **Completed**: 2026-05-29 09:55 IDT **Duration**: 2 minutes **Notes**: * Ran the full root Vitest suite after the final ASCII cleanup: 104 test files passed, 1 skipped, 1837 tests passed, 1 skipped. * Ran focused Biome format and lint checks on touched source/test files: passed with no fixes required after the final patch set. * Ran `git diff --check`: passed. * Ran ASCII validation for touched files and spec-system outputs: passed after replacing remaining non-ASCII punctuation and literals in replay and notification surfaces. * Ran LF validation for touched text outputs: passed. * Ran `npm --workspace apps/server run typecheck`: passed. * Ran `npm --workspace apps/web run typecheck`: first pass caught the new `ToggleRow.disabled` prop type; patched it and reran successfully. **Files Changed**: * `.spec_system/specs/phase02-session06-settings-replay-notifications-and-scan-ux/implementation-notes.md` - recorded final verification results. *** --- # Agent Instructions This documentation is published with GitBook.
