Subject: [PATCH 01/36] fix: auto-find free CDP port when default 9334 is busy

Electron main process now probes if the preferred CDP port is
available before starting. If busy (zombie process, etc.), it
auto-finds a free port in the 9335-9399 range. Also added timeouts
to lsof/kill calls to prevent hangs on zombie processes.

Subject: [PATCH 02/36] feat: per-actor colored cursors with auto-palette

- Replaced hardcoded alice/bob/narrator palette with rotating
  8-color auto-palette (coral, sky, lime, violet, amber, teal, rose, indigo)
- First actor gets classic white cursor, subsequent actors get colored
- Cursors start hidden, appear on first moveCursor call
- Non-default cursors show a colored label with the actor name
- Each actor gets cursorId from pane title (e.g. 'boss', 'worker')
- Cursor overlay injected once for all actors (lazy creation)
- Cursors fully cleaned up on scenario switch

Subject: [PATCH 03/36] fix: stop button, cursor colors, cache button, CDP port
 fallback

Stop button:
- Added _aborted flag to Executor, checked between steps in runTo()
- Wrapped runAll loop in try/catch to handle abort cleanly
- Cancel now sends 'cancelled' to client on abort

Cursor improvements:
- Removed cursor labels (colors-only differentiation)
- First cursor appearance teleports without transition (no corner slide)
- Cursors start hidden until actor's first interaction

UI:
- Cache button text: 'Clear cache (2.5 MB)' format
- CDP port auto-fallback when default 9334 is busy

jabterm v0.1.4 adds:
- accessibilitySupport prop (populates .xterm-rows text natively)
- Resize deduplication (skips WS resize when cols/rows unchanged)

Cleanup:
- Removed data-b2v-output polling hack from TerminalPane
- Removed jabtermRef (no longer need readAll() capture buffer)
- Removed data-b2v-output fallback from waitForText/waitForPrompt
- Added accessibilitySupport="on" to JabTerm component

Subject: [PATCH 05/36] fix: xterm v6 accessibility tree + cursor first-use
 teleport

TUI timeout fix:
- xterm v6 puts accessible text in .xterm-accessibility-tree, not .xterm-rows
- Updated waitForText, waitForPrompt, isBusy, and grid prompt wait
  to check .xterm-accessibility-tree first, .xterm-rows as fallback

Cursor positioning:
- Added _cursorInitialized flag to Actor class
- First cursor movement teleports to target instead of windMouse from (0,0)
- Applied to both moveCursorTo() and private moveTo() (used by click/hover/type)
- Prevents cursors appearing at edge of player window

Subject: [PATCH 06/36] feat: improve chat scenario + xterm v6 test selectors

Chat scenario:
- Split intro into 'Introduction' (narration) + 'Meet the actors' (circleAround)
- Alice and Bob type concurrently via Promise.all
- Added Web Audio API notification beep when Bob sees Alice's message
- Removed emoji chars from typed messages (caused rendering artifacts)

E2E tests:
- Added XTERM_TEXT_SELECTOR constant for xterm v6 compatibility
- Updated all .xterm-rows selectors to check .xterm-accessibility-tree first

CSS buttons scenario: works with xterm-accessibility-tree fix in terminal-actor

Subject: [PATCH 07/36] fix: resolve keyboard contention in concurrent actor
 typing

All actors share one page.keyboard, so Promise.all interleaves chars.
Fix: Bob types a slow-output bash script first (sequential keyboard),
then Alice types while Bob's script runs in the background producing
progressive 'compiling module N...' output. Visually concurrent
without keyboard conflict.

 etc.)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Command panes (type=terminal with cmd) show their own TUI,
not a shell prompt. Previously the grid creation wait checked
for $/#/% chars in xterm content — this would timeout for mc/htop.

Now: command panes wait for any non-empty xterm content,
shell panes (no cmd) still wait for prompt characters.

Subject: [PATCH 13/36] feat: replace github-mobile test with external-website
 test

New test visits alexn.pro portfolio, finds Three Charts project,
navigates to the demo page (holiber.github.io/three-charts/demo/),
and interacts with the chart: switches line/bars view, changes
timeframes (5m, 30m, 1h), and toggles trend overlays.

Deleted: github-mobile.scenario.ts, github-mobile.test.ts
Added: external-website.scenario.ts, external-website.test.ts

Subject: [PATCH 14/36] fix: skip Electron-only tests in headless mode

collab and all-in-one tests require Electron CDP for
createTerminalGrid(). Marked as test.skip in headless
Playwright runner. They pass via apps/player E2E tests.

Full test results:
- 7 passed, 4 skipped, 0 failed (headless)
- 3 passed (Electron E2E: all-in-one, collab, tui-terminals)

Subject: [PATCH 15/36] fix: add cursor movement to external-website scenario

The cursor overlay is only visible after its first moveCursorTo()
call. scroll() alone doesn't trigger cursor visibility. Added
explicit moveCursorTo() before scrolls and after page transitions
so the cursor is visible throughout the scenario.

createGrid was waiting for shell prompt chars ($/#/%) in ALL
terminal panes, including mc and htop which are TUI apps that
never show prompts. Now: command panes (pc.cmd set) wait for
any non-empty xterm content, shell panes still wait for prompts.

TUI E2E test now passes in 18.8s instead of hanging.

Subject: [PATCH 19/36] fix: register cursor overlay as init script for
 reliable cross-navigation cursor

The cursor overlay was only injected via page.evaluate() which gets
wiped on navigation. The framenavigated listener tried to re-inject
but raced with page load (catch swallowed errors).

Now CURSOR_OVERLAY_SCRIPT is registered as addInitScript so it
persists across all navigations automatically. framenavigated
listener kept as belt-and-suspenders fallback.

Subject: [PATCH 20/36] fix: make cursor overlay script safe for init-script
 (body-deferred)

CURSOR_OVERLAY_SCRIPT now guards all document.body/head operations:
- getCursorEl() returns null if body not ready
- Ripple container lazy-created via ensureRippleContainer()
- Animation style deferred to DOMContentLoaded if head not ready
- moveCursor/clickEffect gracefully no-op when body unavailable

Eliminates 'Cannot read properties of null (appendChild)' errors
when script runs as addInitScript before DOM is ready.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added Session.abort() that immediately closes all browser pages
and contexts, interrupting any running Playwright operations.
Unlike finish(), it skips video composition entirely.

Added Executor.abort() that calls session.abort() and resets state.
Server cancel handler now uses executor.abort() instead of
executor.reset() which previously tried to gracefully finish.

The running step's Playwright operation (goto, waitForSelector, etc.)
throws when the page is force-closed, which propagates up through
runTo() → runAll catch handler → sends 'cancelled' to UI.

Added E2E test: loads basic-ui, clicks Play All, waits for Stop
button, clicks Stop, verifies Play All button returns.

Subject: [PATCH 22/36] feat: add InjectedActor for in-page cursor injection
 and player self-test

- New InjectedActor class (packages/browser2video/injected-actor.ts)
  - Injects visible cursor overlay + typing into any page via page.evaluate()
  - Reuses CURSOR_OVERLAY_SCRIPT, WindMouse cursor paths, real mouse.click()
  - API: click, type, pressKey, waitFor, scroll, goto, breathe

- Player self-test E2E (apps/player/tests/player-self-test.e2e.test.ts)
  - InjectedActor drives the player's own studio UI
  - Tests: cursor injection, + placeholder, Browser popup, URL dialog, iframe

- Human-mode demo runner (apps/player/tests/human-mode-demo.ts)
  - Captures screenshots at each step for visual verification

- Export InjectedActor from browser2video package

Subject: [PATCH 23/36] feat: player-tests-player scenario via defineScenario

- New tests/scenarios/player-self-test.scenario.ts
  - Setup spawns inner Electron player on port 9581
  - session.openPage() connects to inner player's web UI
  - InjectedActor drives the studio UI with visible cursor
  - 5 steps: verify ready, open picker, click +, Browser, URL confirm

- Fixed electron binary resolution via createRequire from player pkg
- All 5 steps pass in ~6.6s

Subject: [PATCH 24/36] feat: comprehensive player self-test scenario (15
 steps, 6 phases)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Phase 1: Split screen horizontally, add terminal
- Phase 2: Launch demo vite server in terminal, open todo app
- Phase 3: Todo CRUD — add 8 todos, reorder, scroll, delete
- Phase 4: Close terminal, verify todo app stops working
- Phase 5: Load basic-ui scenario, play/stop, step through slides
- Phase 6: Assert no unexpected console errors

Also adds data-testid attributes to controls (ctrl-play-all, ctrl-stop,
ctrl-next, ctrl-prev, ctrl-reset), scenario-picker (picker-select,
picker-switch), and step-graph (step-card-{i}).

Subject: [PATCH 25/36] fix: make player-self-test work inside the Electron
 player app

Three fixes for running the self-test inside the Player's Executor:

1. Viewport tracking: add page.setViewportSize({width:1280,height:720})
   after setup. Electron's WebContentsView starts at 0x0 and is later
   resized via IPC, but Playwright's CDP-side viewport tracking keeps
   the initial 0x0 value, causing all elements to be reported as
   'outside of the viewport'.

2. Electron binary resolution: require('electron') returns the module
   object (not the binary path) inside Electron's runtime. Fixed by
   reading electron/path.txt or falling back to process.execPath.

3. Port conflict: changed inner player ports from 9581/9385 to
   9591/9395 to avoid collision when the root player is running.

Subject: [PATCH 26/36] fix: hide inner player window when running embedded

When the player-self-test scenario spawns an inner player, set
B2V_EMBEDDED=1 so the inner player's Electron window is hidden.
The inner player's UI is rendered inside the root player's scenario
WebContentsView, so showing a second window was incorrect.

Subject: [PATCH 27/36] fix: hide inner player window + add cleanup assertions
 (16 steps)

- Inner player window: off-screen (-10000), 1x1 size, show:false,
  skipTaskbar:true via B2V_EMBEDDED=1 env var.

- New step 'Inner player shuts down cleanly': sends SIGTERM, waits for
  exit (10s timeout), verifies exit code, probes port 9591 is freed.

- addCleanup is now a safety-net that only kills if process is still alive.

- 16/16 steps pass both standalone and inside the Player app.
  All steps produce screenshots for the step graph.

Subject: [PATCH 28/36] feat: CDP screencast video recording for Electron/human
 mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When running in Electron mode (CDP endpoint), Playwright's recordVideo is
unavailable because the session connects to existing pages rather than
creating new browser contexts. Added CdpScreencastRecorder class that:

1. Starts Page.startScreencast via CDP to capture JPEG frames
2. Pipes frames to ffmpeg (image2pipe -vcodec mjpeg) → raw webm
3. Stops screencast and waits for ffmpeg to finish in finish()

The raw webm is then processed by the existing composeVideos pipeline.

Also fixed libx264 'height not divisible by 2' error by adding
pad=ceil(iw/2)*2:ceil(ih/2)*2 to reencodeToMp4 and the fallback path.

Verified: 5203 frames captured, 1.4MB MP4 output, 16/16 steps pass.

Single-file runner that:
1. Launches the Player Electron app
2. Connects via WS and loads the player-self-test scenario
3. Runs all 16 steps with progress reporting
4. Reports pass/fail, video path, and duration
5. Cleanly shuts down the Player

Run: node --experimental-strip-types --no-warnings apps/player/tests/run-self-test.ts

Removes the old test-player-ws.ts helper.

Subject: [PATCH 30/36] fix: aggressively hide inner player window + add
 overlap assertion

Electron embedded window hiding:
- type: 'toolbar', focusable: false, hasShadow: false
- mainWindow.hide() + minimize() after creation
- Re-hide after each loadURL() call (macOS can show windows)

Self-test: new 'Inner player window is hidden' step uses osascript
to enumerate all Electron windows and flag any large windows near
origin that could overlap the parent player.

17/17 steps pass, 123.5s, video produced.

Subject: [PATCH 31/36] fix: embedded player rendering, custom cursor colors,
 startup time

- Disable electronView when B2V_EMBEDDED=1 to fix black background
- Enable CDP screencasting in executor for embedded mode
- Add __b2v_setCursorColor() for custom per-actor cursor colors
- Add cursorColor option to InjectedActor (coral for self-test tester)
- Add port cleanup before spawning inner player (kills stale processes)
- Reduce post-waitForPort delay from 3s to 1s
- Add 'Verify scenario screenshots are not blank' assertion step
- Remove broken React CursorOverlay from screenshot mode

+# Player Self-Test
+
+## Running
+
+```bash
+# Fast mode (CI, headless, ~2.5 min)
+pnpm self-test
+
+# Human mode (headed, visible cursor + 1s breathe pauses, ~3 min)
+pnpm self-test:human
+
+# Headed but fast (visible window, no animation delays)
+pnpm self-test -- --headed
+```
+
+`--human` sets `B2V_HUMAN=1` which:
+- Enables human mode (visible cursor animations, 1s breathe pauses between actions)
+- Auto-enables `--headed` (Electron window is visible on screen)
+
+`--headed` alone shows the window but keeps fast mode (no delays).
+
+## Architecture
+
+The self-test **uses the player to test the player**:
+
+1. Playwright launches the outer player (Electron)
+2. Selects `player-self-test` scenario via the picker
+3. Clicks "Play All"
+4. Monitors all steps until completion
+
+The actual test logic lives in `tests/scenarios/player-self-test.scenario.ts` which:
+- Spawns an **inner** player (Player B) as a child process
+- Opens Player B's web UI in the outer player's session
+- Uses `InjectedActor` to drive Player B's UI (cursor visible in-page)
+
+## Test Steps
+
+- actor should split screen horizontally and open the terminal in bottom pane
+- actor launches our demo app in terminal and once it ready actors create a browser page with todo app
+- ensure we can add todos, reorder them and scroll when there are too many todos (looks like we need to inject another actor to work there)
+- after that player closes the terminal, and make sure the todo app doesn't work anymore
+- after that player opens basic ui scenario and play it
+- once it's played it replay it and click stop after first slide, and go through all slides one by one
+- we should ensure we don't have errors in consoles
+
+## Mode Behavior
+
+| Feature | Fast mode | Human mode |
+|---------|-----------|------------|
+| `breathe()` | Always 0ms (instant) | 1000ms pause |
+| Cursor movement | Instant teleport | Smooth wind-mouse animation |
+| Click effects | Instant | 25ms ripple + 300ms after-click |
+| Typing | Instant | 35ms per keystroke |
+| `--headed` | Optional | Auto-enabled |

  *
- * This validates both:
- * 1. The InjectedActor API (cursor injection, clicking, typing)
- * 2. The player UI (studio mode, pane popups, URL dialog)
+ * This is "using our player to test our player".

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove fixed 1s post-waitForPort delay
- Switch from networkidle to domcontentloaded (faster)
- Reduce studio-react retry attempts from 5 to 3 (with 15s timeout)
- Add timing instrumentation to setup phases
- Total time: 2.6m → 2.4m

Subject: [PATCH 33/36] feat: custom cursor colors for player and scenarios

- Add cursorColor to SessionOptionsSchema, Session, and Actor
- Session reads from opts or B2V_CURSOR_COLOR env (format: fill,stroke)
- Actor.injectCursor() applies color via __b2v_setCursorColor
- Session adds cursor color init script for navigation persistence
- Self-test: pink tester cursor, orange scenario Actor cursor
- Both cursors visually distinct during self-test playback

- Increase cursor from 20x20 to 32x32px for visibility in screencast JPEGs
- Add drop shadow filter for contrast against any background
- Tester cursor: hot pink (#ff69b4) — unmistakably distinct
- Scenario cursor: orange (#fb923c) via B2V_CURSOR_COLOR env

Subject: [PATCH 35/36] fix: move addInitScript before page.goto for cursor
 color to work
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Root cause: addInitScript calls were placed AFTER page.goto() in
session.ts openPage(). Playwright addInitScript only fires on
*subsequent* navigations — so the cursor overlay script ran (via
framenavigated fallback), but the cursor color init script never
executed on the initial page load.

Diagnostic confirmed: inner player showed cursors=0 colors={} before
fix, and cursors=1 colors={default:{fill:#fb923c}} after fix.

Also removed temporary diagnostic code from executor.ts and
player-self-test.scenario.ts.
