Roadmap: Mokosh

Overview

The Mokosh codebase is a partially-broken first attempt at SPEC Тз расширение фаза1.md. An external audit identified 7 P0 defects that prevent SPEC §10 acceptance. This roadmap therefore frames Phase 1 as stabilization to spec, not greenfield: phases 1–3 each remediate a tightly-grouped subset of the P0 defects along sensible commit boundaries; phase 4 runs the SPEC §10 smoke pass end-to-end. An optional phase 5 absorbs the P1/P2 follow-ups (SW state persistence, fetch interception fix, meta.json field hardening, generate-icons.js ESM/CJS, dead-code cleanup).

The journey: broken-but-installable → playable video → masked DOM + log → working export → green §10 smoke → harden + clean up.

Phases

Phase Numbering:

• Integer phases (1, 2, 3): Planned milestone work.
• Decimal phases (2.1, 2.2): Urgent insertions (marked with INSERTED).

Decimal phases appear between their surrounding integers in numeric order.

• Phase 1: Stabilize video pipeline — Collapse offscreen duality, fix MediaRecorder shadow, fix WebM ring buffer playability, replace chrome.tabCapture with offscreen getDisplayMedia (AMENDED from original DEC-003). Closed 2026-05-15 then REOPENED 2026-05-16: the 2026-05-15 closure was based on insufficient operator playback verification; D-13's concat-of-self-contained-segments architecture produces a multi-EBML WebM that plays only ~9 s instead of ~30 s in standards-compliant parsers (mpv, ffmpeg, Chrome HTMLMediaElement). UAT Test 3 retest on 2026-05-16 confirmed via byte-level EBML probe. SPEC §10 #7 not actually satisfied. Plan 01-08 (WebM remux via ts-ebml + webm-muxer) replaces mergeVideoSegments's file-concat with a real single-EBML remux. See .planning/debug/d13-multi-ebml-concat-unplayable.md. Option C port-lifecycle refactor (debug session empty-archive-port-race) DID land cleanly and is retained. Phase 1 will additionally absorb whole-desktop + auto-start UX work (Plans 01-09/01-10) per the 2026-05-16 amended charter.
• Phase 2: Stabilize DOM + event capture privacy — Migrate rrweb to v2 maskInputFn, plug content/index.ts setupInputLogging password leak
• Phase 3: Stabilize export pipeline — Restore user-activation gesture in popup, delete dead permissions.request, replace base64 data: URL with Blob URL minted in offscreen
• Phase 4: SPEC §10 smoke verification — End-to-end install-and-record-and-export pass against all 9 acceptance criteria
• Phase 5: Harden + clean up (optional) — P1/P2 follow-ups: SW state persistence, fetch interception, meta.json fields, generate-icons.js ESM/CJS, dead-code

Phase Details

Phase 1: Stabilize video pipeline

Goal: The video ring buffer captures the most recent 30 s of the active tab's video continuously across tab switches, with a playable WebM header retained — so that on export the assembled last_30sec.webm will play.

Depends on: Nothing (first phase). Operates on the existing offscreen/ directory + vite.config.ts inline string + src/background/.

Requirements: REQ-video-ring-buffer

P0 defects addressed:

• P0-1: Collapse the offscreen duality (offscreen/index.ts + inline string in vite.config.ts) into a single source of truth; fix the mediaRecorder shadow that breaks stopRecording.
• P0-2: Fix WebM ring buffer playability — single continuous MediaRecorder, 2000 ms timeslice per spec (CON-video-codec), cluster-timestamp-based rolling window honouring the WebM header retention rule (DEC-009).
• P0-3: Make capture always-on with chrome.tabs.onActivated / chrome.tabs.onUpdated re-attachment; start on onInstalled / onStartup, not on popup open (CON-tab-capture-binding, REQ-video-ring-buffer).

Success Criteria (what must be TRUE):

1. There is exactly one source of truth for the offscreen document; rebuilding vite.config.ts does not regenerate a divergent inline duplicate, and stopRecording runs without mediaRecorder is undefined shadow errors.
2. With the extension loaded and an operator session active, a MediaRecorder is running on the operator-selected screen/window source. AMENDED 2026-05-15 (D-13 fix-a3 activation): the recorder cycles in 10 s self-contained segments (stop+restart on the same MediaStream) instead of a single continuous recorder — replaces D-09..D-11 to fix VP9 keyframe orphan-P-frame freezes. Recording continues unchanged across tab switches (no tab re-attach logic; AMENDED from the original wording).
3. The in-memory video ring buffer at any instant contains at most 3 of the most recent 10 s WebM segments (3 × 10 s = 30 s window, no more, no less); concatenating segments sequentially yields a multi-EBML-header WebM that Chrome plays end-to-end (SPEC §10 #7 — operator confirmed clean playback 2026-05-15; ffmpeg -v warning -i fixture -f null - exit 0 with zero decoder errors, only expected muxer DTS-monotonicity warnings at segment join boundaries).

Plans: 14 plans (01-01 through 01-14). All 14 functional plans complete; Phase 1 final-closure marker flip pending.

• 01-01-PLAN.md — Doc cascade: amend DEC-003 / DEC-010 / RETIRE constraints / swap manifest permissions (D-A1..D-A6)
• 01-02-PLAN.md — Wave-0 test infrastructure: Vitest install + 4 RED test files + fixtures placeholder

• 01-07-PLAN.md — Manual smoke + ffprobe D-12 acceptance gate + A3 empirical-playback gate; D-12 + A3 debug sessions resolved mid-execution via pre-staged base64 wire format + D-13 restart-segments; regression fixture committed; SPEC §10 #2/#3/#7 functionally green (Closed 2026-05-15)
• 01-08-PLAN.md — WebM remux via ts-ebml + webm-muxer (replaces D-13 file-concat; closes SPEC §10 #7 playability per debug d13-multi-ebml-concat-unplayable.md)
• 01-09-PLAN.md — Toolbar onClicked direct flow + monitor-only picker + onStartup notification + 3-state badge state machine; closure-by-harness Amendment 2 (Plan 01-13 PASS substitutes for operator UAT). Closure-cycle follow-up debug a2dfc8c (startVideoCapture no-tab cleanup; D-01 dead-code removal) + 4bba679 (notifStartup text split into notifStartupCta + notifRecordingStarted) landed during Plan 01-10 closure 2026-05-20.
• 01-10-PLAN.md — Welcome tab (Hero + Loom dial per D-02; first-install onboarding; chrome.runtime.onInstalled + chrome.storage.local flag-gating + chrome.tabs.create + canonical mokosh-mark.svg via Vite ?url import + canonical src/shared/tokens.css @import + chrome.i18n.getMessage for welcomeHeroRu + welcomeHeroEn; harness A15-A17 with A17.7 --mks-rec probe + A17.8 mark-bundling invariant; D-16-toolbar charter preserved). Closure 2026-05-20 via cycle-2 operator ack "All good" + 5 inter-cycle debug fixes (89e1e09 → 49f087f → 8f329d8 → b112cb7 → 4bba679 → d48a715 → 0854baf → a2dfc8c → d21ed17) + brand-rename follow-up "AI Call Recorder" → "Mokosh"; 153/153 vitest + 24/24 UAT GREEN.

• 01-12-PLAN.md — Design integration (R2 Lora self-host, src/shared/tokens.css canonical, 16 i18n keys across en+ru, branded Loom icons replacing Bug A placeholders, manifest i18n + default_locale='en', BADGE_REC_COLOR madder #b2543d, chrome.i18n.getMessage with || <const> fallback, harness A18-A22; operator brand-fit ack 2026-05-20 'all good')
• 01-13-PLAN.md — UAT harness via Approach B (extension-internal-page driver + offscreen synthetic stream; 15/15 GREEN; Plan 01-09 functional closure)
• 01-14-PLAN.md — Picker narrowing via monitorTypeSurfaces:'include' (Chrome 119+ picker enhancement; A23 harness regression)

Phase 2: Stabilize DOM + event capture privacy

Goal: rrweb captures DOM events on typical pages and the user-event log captures clicks/navigation/network errors — and in neither stream do password values appear.

Depends on: Phase 1 (no functional dependency, but Phase 1 establishes the "capture is always-on" baseline that this phase plugs into).

Requirements: REQ-rrweb-dom-buffer, REQ-user-event-log, REQ-password-confidentiality

P0 defects addressed:

• P0-5: rrweb data-sensitive leak — migrate to rrweb v2 maskInputFn (the legacy maskInputSelector is gone in v2.0.0-alpha.4 per package.json); fix the parallel leak in src/content/index.ts setupInputLogging so password field values are dropped at logger entry, not just at rrweb level.

Success Criteria (what must be TRUE):

1. On a page containing <input type="password"> and elements with data-sensitive="true", rrweb snapshots for that page mask the value of both kinds of fields (verified by inspecting exported rrweb/session.json).
2. On the same page, typing into a password field produces no input event entry containing the typed value in the user-event log (logs/events.json).
3. On a typical page with forms, tables, and a modal, rrweb records DOM events without throwing in the Content Script console; the event log captures clicks, navigations (popstate/hashchange), and network errors (fetch / XHR >= 400).

Plans: TBD UI hint: yes

Phase 3: Stabilize export pipeline

Goal: A click on "Сохранить отчёт об ошибке" produces a SPEC-conformant ZIP archive on disk in under 5 s, containing a screenshot taken at click time, laid out per CON-archive-layout, with meta.json per CON-meta-json-schema, and declared by a manifest carrying exactly the permission set in DEC-011.

Depends on: Phase 1, Phase 2 (export consumes the video + rrweb + event-log buffers established by phases 1 and 2).

Requirements: REQ-popup-ui, REQ-screenshot-on-export, REQ-archive-layout, REQ-meta-json-schema, REQ-archive-export-latency, REQ-manifest-permissions

P0 defects addressed:

• P0-4: Restore the user-activation gesture for getMediaStreamId by moving the call to the popup-click handler; delete the dead permissions.request dance that was masking the missing gesture (REQ-popup-ui, CON-tab-capture-binding).
• P0-6: Replace the base64 data: URL download with a Blob URL minted in the offscreen document — the Service Worker lacks URL.createObjectURL (DEC-006, REQ-archive-export-latency).

Success Criteria (what must be TRUE):

1. Opening the popup shows a button reading "Сохранить отчёт об ошибке" with sub-label "Последние 30 сек видео + 10 мин лога"; clicking it transitions idle → "Сохраняю..." → "Готово! ✓" → idle (with 3 s revert) and triggers a chrome.downloads download.
2. The downloaded file lands in the user's Downloads folder, named session_report_YYYY-MM-DD_HH-MM-SS.zip, in under 5 seconds from click; opening it reveals exactly the layout in REQ-archive-layout (video/last_30sec.webm, rrweb/session.json, logs/events.json, screenshot.png, meta.json at the root) with no extra entries.
3. meta.json validates against the verbatim CON-meta-json-schema (all 7 fields present, types correct, timestamp is ISO-8601 with Z).
4. manifest.json in dist/ after npm run build declares exactly the permission set in DEC-011 with no additional or missing entries; loading unpacked into Chrome produces no permission-related warnings or errors in chrome://extensions/.

Plans: TBD UI hint: yes

Phase 4: SPEC §10 smoke verification

Goal: All 9 SPEC §10 acceptance criteria pass against an unpacked load of the build into a real Chrome instance.

Depends on: Phase 1, Phase 2, Phase 3.

Requirements: REQ-install-clean (and end-to-end verification of all preceding REQs)

P0 defects addressed:

• P0-7: End-to-end smoke verification against §10. This is a verification phase, not a new implementation — it confirms the cumulative output of phases 1–3 actually satisfies the SPEC.

Success Criteria (what must be TRUE):

1. The extension installs into Chrome via "Load unpacked" against dist/ with no errors or warnings in chrome://extensions/.
2. With the extension loaded and a normal browsing session under way, the video buffer runs continuously across tab switches and never holds more than 30 s of footage (confirmed by inspecting the SW console / a debug export).
3. On a typical page (form + table + modal) rrweb records without throwing, the event log captures clicks/navigation/network errors, and passwords are absent from both streams.
4. A click on the popup button produces a ZIP in Downloads in under 5 s; the ZIP opens; video/last_30sec.webm plays in a browser.
5. Background RAM consumption (measured via Chrome Task Manager) does not exceed 50 MB during a sustained recording session (CON-ram-ceiling).

Plans: TBD

Phase 5: Harden + clean up (optional)

Goal: Eliminate the P1/P2 follow-ups identified in the audit so that the codebase is not just spec-conformant but maintainable. This phase has no new v1 requirements — it improves robustness and removes technical debt around already-shipped behaviour.

Depends on: Phase 4 (do not harden until §10 is green).

Requirements: none (no new v1 REQs; all v1 REQs are covered by phases 1–4)

P1/P2 items addressed (informative list from the audit, exact scope finalized at plan time):

• SW state persistence around the 30 s idle unload edge cases.
• fetch interception fix in the network-error path of REQ-user-event-log.
• meta.json field hardening (timestamp source, version source, totalEvents derivation).
• generate-icons.js ESM/CJS compatibility with the rest of the toolchain.
• Dead-code cleanup (the permissions.request dance removed in Phase 3 may have stranded helpers; the offscreen duality removed in Phase 1 may have stranded shims).
• getDisplayMedia cursor visibility constraint (video: { cursor: 'always' }) — refines capture quality for diagnostic UX; surfaced during Phase 1 smoke (2026-05-15) as a user observation. Operator's screen cursor was absent from captured frames despite being the highest-signal cue when reproducing pointer-driven bugs. Constraint is opt-in per the getDisplayMedia spec and Chrome implements it via the CursorCaptureConstraint enum (always / motion / never).

Success Criteria (what must be TRUE):

1. After running the extension idle for >5 minutes, then exporting, the archive still contains a non-empty video buffer (proves SW state persistence works across one or more SW unload/reload cycles).
2. A page that issues a failing fetch (response code >= 400) produces a network_error entry in events.json; a failing XMLHttpRequest does too.
3. npm run build and node generate-icons.js both succeed under the project's module setting ("type": "module" in package.json) with no require is not defined or Cannot use import statement outside a module errors.
4. A repo grep for the symbols deleted in phases 1 and 3 (permissions.request, the duplicate offscreen inline string) returns no live references.

Plans: TBD
