0.15.37: harden Chrome input targeting

0.15.37: clarify README installation instructions (#4)

Clarify README installation instructions (#4)

0.15.36: richer chrome_snapshot + chrome_find/chrome_inspect

- chrome_snapshot returns a concise observation (layout, hints, actions, forms,
  page map, query matches, diff) with mode/query/maxTextChars params
- new chrome_find (query -> ranked uids) and chrome_inspect (deep element context,
  with page.inspect fallback)
- includeSnapshot on click/type/fill/key now embeds the formatted snapshot
- snapshot/inspect logic shipped as eval-free packaged snapshot_injected.js,
  sharing window.__PI_CHROME_STATE__ (el- uid scheme) with existing input helpers

0.15.35: persist /chrome authorize grant across /reload (re-register chrome_* tools on session_start)

0.15.34: tabs Pi uses join session group; fix punctuation dropped by chrome_type/chrome_key (US-layout keymap)

0.15.33: default background mode on (chrome_* run without focusing Chrome)

0.15.32: session tab-group title uses 'Pi Session: <name-or-id>' (colon)

0.15.31: per-session tab groups named 'Pi Session <name-or-id>'

0.15.30: chrome_tab grouping — auto-group Pi tabs, group/ungroup actions, merge by title

0.15.29: CSP bypass via CDP Runtime.evaluate for evaluate/snapshot/waitFor/initScript

- evaluateInTab/executeInTab now run through CDP Runtime.evaluate instead of
  new Function() in MAIN world, so chrome_evaluate/chrome_snapshot work on pages
  that block unsafe-eval (github.com, many bank/SaaS apps). Preserves value
  markers (undefined/function/symbol/bigint/Error), DOMRect expansion, and the
  expression/statement fallback; keeps {ok,value} error envelope.
- page.waitFor polls via service-worker-side CDP evaluation.
- chrome_navigate initScript uses Page.addScriptToEvaluateOnNewDocument.
- Add npm test (test-suite/unit/csp-eval.test.mjs) and in-browser regression
  challenge 42 strict-csp-evaluate; update challenge 39 notes + docs/primer.

0.15.28: bridge self-heal, timeout diagnostics, pressKeyInPage helper, DOMRect serialization, stale-target errors, pageMutated wording

chore: release v0.15.27

chore: standardize gitignore

0.15.26: update docs for benchmark gates

0.15.25: fix reload after stale singleton

0.15.24: unload Chrome tools when locked

0.15.23: attribute fork features

0.15.22: pull fork improvements

feat: lazy-register chrome tools until /chrome authorize

Defer all pi.registerTool() calls until /chrome authorize fires.

Previously, 18 chrome_* tool definitions + chrome-profile-bridge
primer consumed ~5K tokens/turn even when Chrome control locked.

Changes:
- Add chromeToolsRegistered flag (default false)
- Wrap all pi.registerTool() calls in registerChromeTools(pi)
- Only register tools when authorizeFor() runs
- Make before_agent_start conditional: primer injected only when
  tools registered AND authorized
- No tools exist in context until user explicitly allows it

Saves ~5,000 tokens/turn when Chrome control is locked.

silence startup notify + dynamic status bar

- Remove startup notification about companion extension
- Remove static 'Chrome bridge :17318' status bar entry
- Add updateChromeStatus() helper: shows green dot + 'Chrome Bridge'
  only when authorized, clears otherwise
- Call from session_start, authorizeFor, revokeHandler

fix: capture early console/network messages at document_start

Adds an early-capture script injected at document_start on every
navigation via webNavigation.onCommitted + injectImmediately:true.

Wraps console.*, fetch, and XMLHttpRequest before page JS runs, so
console messages, errors, unhandled rejections, and network requests
during page load are captured in window.__PI_CHROME_STATE__.

Sets __piChromeWrapped flags so the existing post-hoc
installPiChromeInstrumentation() is idempotent (checks instrumentationInstalled).

Fixes chrome_list_console_messages returning empty for errors
that fire during React render / initial API calls.

0.15.21: version bump

Tree-equivalent to v0.15.20 (preceded by the revert commit). Bumping
to 0.15.21 sets the package up for normal patch releases on the 0.15.x
line going forward — no version-number collisions with the unpublished
0.16/0.17 work.

Revert 0.16.x and 0.17.x: restore tree to v0.15.20 state

Reverts the pairing + signed-envelopes work (0.16.0-0.16.1), the
standalone daemon refactor (0.17.0-0.17.3), and assorted patches.
These were unpublished from npm; this commit restores the working
tree to match the v0.15.20 release so the branch tip and the npm
'latest' dist-tag are consistent again.

Tags v0.16.0 through v0.17.3 are preserved as recovery anchors;
the work is reachable via 'git checkout v0.17.3' if ever needed.

Tree-equivalent to v0.15.20.

0.17.3: daemon self-heal on missing-daemon fetch failure

In 0.17.x the daemon is a separate process that can idle-shut-down
(10 min idle) or be killed externally while Pi sessions are running.
Without self-heal, the next /chrome onboard or chrome_* call surfaces
'fetch failed' instead of recovering.

bridge.admin() now catches the failed fetch, re-runs ensureDaemonRunning
(probe -> spawn if missing), and retries once.

bridge.sendViaOwner() pre-probes /status and spawns the daemon if missing
before issuing the signed /command.

Net effect: a missing daemon transparently respawns instead of bubbling
fetch failed up to the user.

0.17.2: fix /next lastSeenAt + strict daemon version match

Bugs surfaced in real-world 0.17.0/0.17.1 testing:

1. Daemon /next only recorded lastSeenAt AFTER the auth/pair checks. Pre-pair
   the daemon returns needsPairing early without recording the poll, so
   connected stayed false even though the extension was polling. /chrome
   onboard's wait-for-poll loop spun forever on a healthy extension.

   Fix: record lastSeenAt at the top of /next for any chrome-extension
   origin, before auth checks. Onboard now correctly detects 'extension
   alive but unpaired' which is the precise state during pair step.

2. Daemon compatibility was checked at major.minor match. Result: a patch
   release fixing a daemon bug (like #1) couldn't replace the running
   daemon — new Pi client joins old buggy daemon as client.

   Fix: exact version match. Patch releases auto-kill+respawn the daemon.

0.17.1: fix /chrome onboard stuck on 'Waiting for the extension to wake up'

0.17.0 made the daemon own the HTTP listener, but the Pi client's
bridge.status().connected still reflected the local Pi's lastSeenAt
(which is never updated in the daemon model). Onboard's connect-wait
loop spun forever even when the extension was polling the daemon.

Fix: new ChromeProfileBridge.daemonStatus() async helper that fetches
the daemon's /status. onboard, doctor, and status now query that for
the 'connected' flag instead of reading stale Pi-side state.

0.17.0: standalone daemon, no more owner-vs-client topology

The Chrome bridge is now a separate detached daemon at
~/.cache/pi-chrome/<version>/daemon.cjs. Every Pi session is a uniform client;
daemon lifecycle is decoupled from any Pi session. Killing a Pi never breaks
Chrome control, and pi update followed by any new Pi session auto-replaces
an incompatible daemon.

Architecture:
- New extensions/chrome-profile-bridge/daemon.cjs: ~700 LOC, zero deps, runs
  detached. Owns the HTTP listener, BridgeAuth state, command queue, /pair
  handshake. Idle-shuts-down after 10 min of no activity.
- ChromeProfileBridge on Pi side becomes a pure client: start() probes /status,
  spawns daemon if missing/incompatible, kills+respawns if version mismatch.
  send() always uses signed /command. No more server-mode branch.
- New signed /admin RPC for pair-window/reset/status state mutations the
  daemon owns. Pi clients sign with broker key (same contract as /command).
- New /heartbeat for daemon idle-timer keepalive.
- daemon.log at ~/.cache/pi-chrome/<version>/daemon.log.

/chrome pair, /chrome unpair, /chrome onboard now go through /admin RPCs
instead of mutating in-process bridge state.

Removed the foreign-owner takeover dance from /chrome onboard (auto-handled
at session_start now).

Wire protocol is byte-identical to 0.16.x; existing paired extensions don't
need to re-pair. See docs/DESIGN-0.17-daemon.md for the full write-up.

0.16.1: idempotent /chrome onboard + automatic stale-owner takeover

User pain: machines stuck in broken state after pi-chrome upgrades because an old
pi-chrome process kept holding :17318 and /chrome onboard trusted confirm() clicks
without verifying anything. Both fixed.

Idempotent /chrome onboard recovery flow:
- Always resets Pi-side pairing state first (kills half-paired ghosts).
- Step 1 covers both first-install AND v0.15->v0.16 reload (extension service worker
  must reload to gain the /pair logic).
- Actively verifies progress at each step rather than trusting clicks:
  - polls bridge.status().connected (15s window) to confirm the extension polls /next,
  - polls bridge.bridgeAuth.paired to confirm the /pair handshake completed,
  - round-trips a real tab.version command to confirm the signed-envelope path works.
- /chrome install is now an alias of /chrome onboard.

Automatic stale-owner takeover at bridge.start():
- /status now includes bridgeVersion.
- On EADDRINUSE, probe /status with 1s timeout. If unresponsive OR major.minor
  mismatches, locate the owner PID via lsof and kill it (SIGTERM -> SIGKILL),
  then re-bind. Same-version owners are joined as clients (multi-Pi sharing).
- Eliminates the 'stale Pi session holding bridge' class of bugs that broke
  upgrades from 0.15.x.

/chrome status / doctor / onboard no longer hang:
- New probeExtension() short-circuits before bridge.send when the bridge can't
  round-trip (unpaired, or extension hasn't polled recently). Returns immediately
  with an actionable message instead of waiting 5-35s.

0.16.0: mandatory pairing + signed envelopes + cross-process state coherence

Major security hardening of the Chrome bridge driven by red-team findings.

- Mandatory pairing via /chrome onboard (one-time per machine). Bridge pins exact
  chrome-extension:// origin and derives HMAC keys via HKDF. Until paired, the
  bridge returns idle responses and refuses to deliver commands.
- Signed envelopes on /next, /result, /command. HMAC-SHA256 over protocol version,
  direction, method, path, extension ID, bridge ID, timestamp, fresh nonce, and
  SHA-256 of the body. +/-30s clock window; 5-min LRU nonce replay defense on
  both request and response directions; constant-time MAC compare.
- Peer Pi sessions sharing the bridge sign each /command with a broker HKDF key
  (no bearer token transmitted) and verify the owner's signed response.
- Global loopback enforcement. PI_CHROME_BRIDGE_HOST=0.0.0.0 ignored unless
  PI_CHROME_BRIDGE_DANGEROUS_REMOTE=1; loopback check still applies per-endpoint.
- Cross-process state coherence: fs.watch + per-request mtime check on
  ~/.config/pi/chrome-bridge.json. A peer Pi's unpair (or any external rm/edit)
  propagates to the owner's in-memory state before the next privileged verify;
  replay caches reset on key rotation.
- Body cap 1 MiB -> 413. Queue/pending/waiter caps. Malformed JSON -> 400.
  Non-object JSON bodies -> 400 instead of being trusted.
- page.navigate initScript: try/finally around tabs.update, per-call onCommitted
  listener with bounded commit-wait window, one-shot delete in global onCommitted.
  No more stale init scripts firing on later unrelated navigations.
- crypto.randomUUID() command IDs.
- Manifest diet (dropped activeTab); added popup.html/popup.js for the pair UI.

UX:

- /chrome onboard runs install + pair in one interactive flow.
- /chrome help reorganized into First-time / Day-to-day / Maintenance.
- Status bar lights up as green dot only when authorized.
- Early console/network capture at document_start so boot-time React errors and
  initial API calls aren't dropped (ported from DaniBedz/pi-chrome fork).

Docs:

- SECURITY.md threat model rewritten with in-scope / out-of-scope sections.
- README rewritten with the install-then-pair flow front and center.
- CHANGELOG 0.16.0 entry with full patch list.

Make chrome_* tools interruptible via AbortSignal (#1)

Thread the harness AbortSignal through authorizedBridgeSend, the
ChromeProfileBridge send/sendLocal/sendViaOwner paths, and every
chrome_* tool's execute(). Pressing Esc now rejects the in-flight
bridge call immediately (most visibly fixing chrome_wait_for, which
would otherwise block for the full timeoutMs).

pi-chrome 0.15.0: README rewrite — top-3 recipes, sharper comparison table, section reorder

pi-chrome 0.14.9: trusted-mode primer + auto-sync manifest version

- Primer teaches agents the trusted:true escape hatch for CSP-locked pages
  (github.com, banks, many SaaS) where chrome_evaluate/chrome_snapshot throw
  EvalError due to missing 'unsafe-eval'. Agents now self-escalate instead
  of giving up and asking the user.
- Corrects stale primer claim that chrome_evaluate works without 'unsafe-eval'.
- scripts/sync-manifest-version.js wired to npm version + prepublishOnly
  lifecycle hooks; kills the recurring browser-extension manifest version
  drift (cf. 0.14.4, 0.14.8).

pi-chrome 0.14.2: recover from foreign-extension input overlays

When a different Chrome extension (password manager, autofill popup,
etc.) anchors an overlay to the focused input, Chrome's CDP refuses
our Input.dispatchMouseEvent with 'Cannot access a chrome-extension://
URL of different extension'. The CDP target list shows the foreign
chrome-extension:// URL as type:'other' attached to the same tab.

New behaviour in cdp() wrapper:
1. On that specific error for any Input.* call, snapshot CDP targets
   to identify the offending extension id and log it (foreign-ext-
   detected event added to ring buffer).
2. Send Esc via Input.dispatchKeyEvent (key dispatch routes by focus,
   not coordinates, so it bypasses the overlay) to dismiss the popup.
3. Retry the original Input.* call once.
4. If retry still fails, throw a clear error naming the foreign
   extension id and listing three concrete workarounds: disable that
   extension on the page, use Tab-to-focus instead of clicking, or
   run /chrome quiet off.

pi-chrome 0.14.1: harder attachDebugger retry + trusted.debug diagnostic

attachDebugger now:
- Calls chrome.debugger.getTargets() first and force-detaches any stale
  CDP session this extension already owns on the target tab before
  attaching. Stale sessions (left over from SW reloads or sibling
  detach failures) often surface on the next attach as 'Cannot access
  a chrome-extension:// URL of different extension'.
- Retries up to two more times (180ms + 500ms) instead of once. The
  500ms back-off lets Chrome's content-script registration drain on
  fresh navigations.
- Records every attach event (attached, stale-target-found, attach-
  failed, retry-failed) in a 20-entry ring buffer for inspection.

New diagnostic action 'trusted.debug' returns extension version,
trusted mode, attached tabs, the inspected tab's URL/status, current
chrome.debugger.getTargets() output, and the recent attach-event log.
Use to investigate when a specific URL refuses to attach.

pi-chrome 0.14.0: bare /chrome opens SettingsList dialog (space=cycle, enter=save)

Bare /chrome no longer opens a sequential picker. It now opens an inline
SettingsList from pi-tui with two rows:

  Click realism   auto / on / off
  Quiet mode      on / off

Up/Down navigate, Space or Enter cycles the value of the focused row,
Esc closes. Each row's description updates live to match the current
value, so users always see what the active setting means.

When the Chrome extension hasn't been granted the debugger permission
(real-looking clicks unavailable), the Click realism row stays locked
on its current value and the description points to the fix.

Direct subcommands unchanged:
  /chrome status / doctor / onboard
  /chrome clicks [auto|off|on|status]    (no-args still cycles)
  /chrome quiet  [on|off|toggle|status]  (no-args still toggles)

pi-chrome 0.13.0: flatten /chrome tree, cycle-on-pick for clicks/quiet, status header

Reorganises the /chrome command surface:

  /chrome status   - one-line snapshot of connection + click mode + quiet mode
  /chrome doctor   - full health check (unchanged)
  /chrome onboard  - install extension (unchanged)
  /chrome clicks   - cycles auto -> on -> off -> auto when called with no args.
                     Explicit args (auto|off|on|status) still work.
  /chrome quiet    - toggles on/off when called with no args.
                     Explicit args (on|off|toggle|status) still work.

Removes the nested 'settings' wrapper. /chrome settings background/trusted
still functions as a hidden legacy alias but is no longer advertised.

Bare /chrome opens a picker with a one-line status header and cycle-target
labels: 'clicks: auto -> switch to on' / 'quiet: off -> switch to on'. No
second picker; one keypress flips the setting.

Argument autocomplete now returns full-path values (e.g. 'clicks auto') so
pi-tui's whole-argument replacement applies correctly. Top-level suggestions
show clicks / quiet / status / doctor / onboard with descriptions.

User-visible names match the descriptive copy:
  - 'trusted' -> 'clicks' (matches 'real-looking clicks' / 'quiet clicks')
  - 'background' -> 'quiet' (matches 'quiet mode' / 'watch mode')

README + agent prompt primer + internal hint strings updated.

pi-chrome 0.12.1: fix 07/13/21/27/28 anti-automation regressions

- 07 pointer-properties: pass force: 0.5 on every CDP mousePressed so
  PointerEvent.pressure reports 0.5 for trusted clicks (was 0,
  inconsistent with real mouse behaviour).
- 13 focus-order: after a CDP-driven click on a focusable target,
  re-focus with focusVisible: false so :focus-visible matches pointer
  focus semantics (CDP press leaves :focus-visible=true otherwise).
- 21 keyboard-modifiers: chrome.debugger.attach occasionally rejects
  with 'Cannot access a chrome-extension:// URL of different
  extension' immediately after navigation. attachDebugger now waits
  180ms, verifies the tab URL isn't privileged, and retries once.
- 27 scroll-momentum + 28 intersection-visibility: replace gentle
  ~1.25%/step linear taper with a ramp-up (~15%) + geometric decay
  (~12% drop/step). Sizes n adaptively so peak event stays ≲22px so
  small visibility targets get low-ratio IO samples while a clear
  momentum tail remains for decay-pattern detectors.
- trustedDrag mousePressed also gets force: 0.5 (consistency).

pi-chrome 0.12.0: unify slash commands under /chrome

Replaces /chrome-doctor, /chrome-onboard, /chrome-background,
/chrome-trusted with a single /chrome command that takes subcommands:

  /chrome doctor                            (was /chrome-doctor)
  /chrome onboard                           (was /chrome-onboard)
  /chrome settings background [on|off]      (was /chrome-background)
  /chrome settings trusted [auto|off|on|status]   (was /chrome-trusted)

Running /chrome with no arguments opens a picker. Argument auto-
completion walks the tree (e.g. type '/chrome se<Tab>' to land on
'settings', then '/chrome settings t<Tab>' to land on 'trusted').

All user-visible references (notify messages, doctor output, agent
prompt primer, README) updated to the new paths.

pi-chrome 0.11.5: plain-English audit pass for /chrome-doctor, /chrome-background, /chrome-onboard, README

Replaces remaining jargon in every user-facing string:

- /chrome-doctor: 'Local bridge: mode=server, url=...' -> 'This pi
  session is running the Chrome connection for this machine.'
  'EXTENSION VERSION MISMATCH ...' -> 'The Chrome companion extension
  is on an old version (X); this pi-chrome is Y.'
  'chrome_evaluate("1+1") = 2' -> 'pi-chrome can run code in the
  active Chrome tab.'
  'navigator.webdriver=true on current tab — site fingerprinting may
  flag automation.' -> 'Your Chrome is reporting itself as automated
  to websites. Some sites use this signal to block sign-ins or bot
  checks.'
- /chrome-background description + notify: drops 'silent/background
  mode', frames as 'quiet mode' vs 'watch mode'.
- /chrome-onboard: walks through the click-by-click steps instead of
  saying 'Developer mode -> Load unpacked'.
- session_start notify: drops 'Chrome profile bridge'; says 'pi-chrome
  connected' / 'waiting for the Chrome companion to connect'.
- README 'Trusted-input mode (CDP)' section rewritten as 'Click modes'
  with plain prose explaining quiet vs real-looking clicks and when
  each fails.

Tool descriptions (seen by the agent) keep precise terminology.

pi-chrome 0.11.4: drop 'yellow' from banner copy; quote exact banner text

Banner is themed by the user's Chrome (dark mode → dark grey for many
users), not always yellow. Use 'banner' alone or quote the actual
banner text 'Pi Chrome Connector started debugging this browser'.

pi-chrome 0.11.3: plain-English copy in /chrome-trusted + /chrome-doctor

User-facing strings rewritten in layman's terms — no more 'CDP',
'isTrusted', 'user-activation gates', 'synthetic events', 'debugger
API'. /chrome-trusted picker now explains each mode by what users
actually experience: yellow banner, which sites work, when to use it.
/chrome-doctor reports 'Click mode' instead of 'Trusted-input mode'.
Tool descriptions (read by the agent) keep precise terminology.

pi-chrome 0.11.2: cap trustedScroll per-event delta so IO threshold gradient lands

pi-chrome 0.11.1: chrome_tap (CDP touch), smoother trustedScroll, cdp auto-recover

- chrome_tap tool: real browser-trusted touchstart/touchend via
  Input.dispatchTouchEvent for sites that gate on TouchEvent (mobile-
  first PWAs, swipe carousels). Always uses CDP; banner appears.
- trustedScroll: per-step delta capped at ~80px, n=6..60 steps with a
  bell-shaped weight curve, 22-52ms sleep between events so IntersectionObserver and rAF samples get gradient updates (fixes
  intersection-visibility / smooth-scroll tests).
- cdp() wrapper auto-detects stale debugger sessions (tab nav,
  DevTools toggle, manual cancel) and re-attaches+retries once
  instead of throwing 'Debugger is not attached'. Fixes intermittent
  failures during automated test sweeps.

pi-chrome 0.11.0: smart-auto trusted mode default + rename to Pi Chrome Connector

Trusted-input mode default flips from 'off' to 'auto':
- Synthetic events still run first for every chrome_* call.
- If a click produced no page change AND the target's label looks like a
  user-activation-gated affordance (play/copy/share/sign-in/etc), or the
  page just emitted NotAllowedError / 'transient activation required',
  the call is silently retried via chrome.debugger (CDP).
- Typing auto-retries when the input value didn't change at all
  (editor rejected synthetic input).
- Result carries autoRetried=true + autoRetryReason + syntheticAttempt
  so callers / agents see the upgrade happened.
- Yellow debugger banner now appears only for the retry, not every call.

Companion extension renamed 'Pi Existing Chrome Profile Bridge' →
'Pi Chrome Connector' (manifest, action title, SW client name, README,
slash-command notify strings). One-time chrome://extensions reload
needed to pick up the new name; auto-reload mechanism handles the rest.

/chrome-doctor explains the active mode and what smart-retry does.
/chrome-trusted picker shows 'auto (current)' first; on-mode now warned
as 'banner permanently visible'.
chrome_click / chrome_type tool descriptions explain auto-retry.

pi-chrome 0.10.2: interactive /chrome-trusted picker

- No-arg /chrome-trusted now shows ui.select picker with current mode +
  tradeoff for each option (on/off/auto/status)
- First-time on transition asks ui.confirm with banner warning
- Permission missing emits a clear ui.notify with fix instructions
- Direct args (/chrome-trusted on|off|auto|status) still work

pi-chrome 0.10.1: chrome_key modifiers param for trusted chords (Cmd+V etc)

pi-chrome 0.10.0: trusted-input mode via chrome.debugger (CDP)

Add opt-in CDP path so chrome_* tools can dispatch browser-trusted input
(isTrusted=true, satisfies user-activation gates: clipboard, fullscreen,
file picker, autoplay). Default remains synthetic events; no behavior
change unless trusted mode is enabled.

Companion extension:
- new "debugger" permission in manifest (one-time re-approval prompt in
  chrome://extensions on update)
- attach/detach lifecycle per tab with idle-detach (15s) and listener
  for onDetach (incl. canceled_by_user)
- trustedClick / trustedHover / trustedType / trustedFill / trustedKey /
  trustedScroll / trustedDrag use Input.dispatchMouseEvent +
  Input.dispatchKeyEvent through chrome.debugger.sendCommand, reusing
  humanized timing, in-rect coord variance, pointer continuity, Shift
  chord for uppercase, per-key cadence
- trusted.mode / trusted.status bridge actions

Pi side:
- /chrome-trusted slash command (on / off / auto / status)
- trusted=true param on chrome_click, chrome_type, chrome_fill,
  chrome_key, chrome_hover, chrome_drag, chrome_scroll
- /chrome-doctor probes chrome.debugger availability and reports current
  trusted mode + attached tabs
- README documents trusted-input mode and tradeoffs

pi-chrome: humanize synthetic input + anti-automation test suite

Bump 0.8.0 → 0.9.1.

Companion extension (service_worker.js):
- humanise pointer paths: easing Bezier-ish interpolation w/ wobble, 12–42
  steps, 4–18 ms gaps; pointer position persisted across calls
- click point picked inside element rect, not dead center
- pointer events fill movementX/Y, screenX/Y, pressure (0.5 on down),
  pointerId, width/height, tilt, composed
- click sequence: humanMoveTo → pointerdown → focus → 45–140 ms hold →
  pointerup → mouseup → click
- per-character typing: keydown → keypress → beforeinput → value mutate
  (or execCommand for contenteditable) → input → keyup, with 25–95 ms
  hold + 35–140 ms inter-key; auto Shift chord for uppercase/symbols
- pressKeyInPage emits same cadence + handles printable insert / Backspace
- hoverPage: humanised path + 80–220 ms dwell
- dragPage: full HTML5 sequence (dragstart/drag/dragenter/dragover/
  dragleave/drop/dragend) with shared DataTransfer + pointer continuity
- new scrollPage: wheel events with front-loaded momentum-shaped deltas
- self-reload on version drift: SW reads x-pi-chrome-version header,
  reloads when older than pi-chrome

Pi side (index.ts):
- new chrome_scroll tool
- PI_CHROME_VERSION read from package.json (and re-read on every /next
  so future bumps take effect without pi restart)
- /chrome-doctor escalates version mismatch to top-line ✗ error and
  skips downstream capability probes when stale
- /next response carries x-pi-chrome-version header for SW self-heal

Test suite (test-suite/):
- 28 challenge pages each catching a different synthetic-event tell:
  isTrusted, webdriver/fingerprint, mouse entropy/timing/coords,
  pointer pressure/continuity, per-char cadence + framework invariants,
  user activation, honeypots, focus order, wheel scroll, drag+
  DataTransfer, contenteditable+Selection, paste/clipboard, native
  select, hover dwell, React valueTracker, keyboard modifiers, touch
  events, stack-trace fingerprint, viewport-edge clicks, mousemove
  rate, scroll momentum, IntersectionObserver visibility
- shared _lib.js exposes window.__verdict + writes localStorage so
  index.html dashboard aggregates results
- notes/bypass-ideas.md documents fixes still needed per challenge
