* fix(renderer): raise renderer V8 heap toward the 4GB pointer-compression cage
Renderer OOM ('renderer crashed'/'oom', exit 5 / 0xE0000008 / SIGTRAP) is the
dominant crash in the crash channel: the renderer JS heap reaches Chromium's
default V8 old-space ceiling (~RAM/4) and V8 aborts. Two adversarial leak hunts
(13 agents across every renderer subsystem) found no unbounded GB-scale leak, so
this is a capacity ceiling, not a leak.
Chromium sizes the renderer heap at ~RAM/4, leaving 8-15GB machines well under
V8's ~4GB pointer-compression cage (an 8GB machine caps near 2.2GB). Reclaim that
unused headroom via --max-old-space-size in a focused startup module, gated on
physical RAM (>=8GB, ~40% of RAM, floor 3072MB, capped at the real 4096MB cage).
16GB+ machines are already at the cage so this is a no-op for them; low-RAM
machines keep the default to avoid trading a clean OOM for OS memory-pressure
kills.
Overridable with ORCA_RENDERER_HEAP_MB (number to force, default/off/0 to opt
out). Verified on Electron 42.3.3: the main-process js-flags switch propagates to
the renderer V8 and is honored up to the 4096MB cage (5000/12288 -> 4096).

* fix(renderer): address CodeRabbit — floor-to-0 override + Linux 8GB gate
- parseRendererHeapOverrideMb: a fractional override in (0,1) floored to 0 and
emitted an invalid --max-old-space-size=0; treat floored-to-0 as an opt-out.
- Lower the RAM gate from 8 to 7.5 GiB: os.totalmem() on Linux reports MemTotal
(excludes kernel/firmware-reserved RAM), so a real 8 GB box reports ~7.7 GiB
and was wrongly excluded from the headroom — the exact crashing population.
7.5 still cleanly excludes 6 GB machines (report ~5.7 GiB).

110 files carried an eslint/oxlint-disable max-lines directive but are
already under the default max-lines budget (300 .ts / 400 .tsx / 600 .mjs
/ 800 test), so the suppression is dead. Removing it restores real
max-lines coverage on these files with zero behavior change.
Each removed directive had max-lines as its only rule; verified via a
full oxlint run (0 max-lines violations, 0 new errors). Diff is pure
deletions (200 lines, 0 additions) — no code touched.

Bump marketing version 0.0.22 -> 0.0.24 and Android versionCode 4 -> 5.
The 0.0.22 base was never committed after prior releases, so the Jul 6
builds carrying the show-all-worktrees fix (#7500) regressed below the
0.0.23 already on TestFlight (iOS) and collided with the existing
0.0.22/versionCode 4 APK (Android, no upgrade signal). Committing the
bump makes app.json authoritative again so 0.0.24 supersedes both.

Two independent pieces, no behavior change to terminal handling:
1. Daemon lifecycle file log. The detached daemon runs with stdio
ignored, so field failures have zero daemon-side evidence. The daemon
now writes rotated NDJSON lifecycle events (startup/ready/hello
accept+reject/session create/attach/exit/kill/shutdown/uncaught
exceptions) to logs/daemon.log via a new optional --log-file fork arg.
Fail-open (any fs error disables logging), adoption-neutral (old
daemons without the arg keep working, protocol untouched), and the
diagnostic bundle collector now includes the file, bounded by the same
lookback window as trace spans.
2. tools/win-update-e2e: a packaged NSIS update proof harness. Installs
version N, drives the installed app (isolated userData), plants a
canary marker session, silently updates to N+1, relaunches, and
asserts an explicit expectations profile: --expect cold-restore
(today's behavior) or --expect survival (the Phase 1 target). Window
flashes are detected by baseline-diffed window enumeration with
canary-title attribution; daemons are identified by command-line
marker, never exe name. Refuses to run when a pre-existing Orca app is
running or (without --allow-existing-install) installed, and only
uninstalls an install it fully owns.
Ensure agent CLI startup and draft launch commands use the correct quoting
format based on the user's configured local Windows shell (e.g., cmd.exe).
This avoids using host settings for remote/SSH targets where local shell
preferences do not apply.
Issue #7236 reported that any non-empty worktree Setup Script failed on
Windows PowerShell with a "missing terminator" parser error, regardless
of content. Root cause: in pre-encoded builds the setup-runner command
(`cmd.exe /c "<runner>"`) was typed into PowerShell as raw stdin, where a
dropped/unbalanced double quote got re-parsed as an open string.
Encoded-command delivery (base64 UTF-16, shipped in v1.4.81) already
fixes this by passing the command as a shell argument with quotes intact.
This adds a regression test tying resolveSetupRunnerCommand to
resolveWindowsShellLaunchArgs: the real setup-runner command must reach
PowerShell via -EncodedCommand (startupCommandDeliveredInShellArgs),
never raw stdin, with its quotes preserved verbatim.

* Clarify Orca orchestration tool boundary and sidebar lineage
Add a "Tool Boundary" section to the orchestration skill, requiring
explicit Orca runtime state instead of generic subagent tools or
chat-only parallel workers. Also add tests to verify the tool boundary
and clarify sidebar lineage for same-worktree workers.
* Clarify worktree lineage guidance and parent-child boundaries
Update orchestration guidance and tests to clarify when to use child versus
top-level worktree lineages, and when to prefer same-worktree workers.
* Require stating the desired Orca lineage before creating a worktree from
an active feature branch.
* Limit child worktrees to conceptually stacked or dependent tasks.
* Prefer same-worktree workers unless isolated checkouts are explicitly
needed and do not require uncommitted changes.
getProcessTableSnapshot deduped the ps fork (#6288/#6667) but cached only the
raw stdout string on POSIX, so every concurrent agent pane re-ran parsePsRows
over the identical output within each 500ms TTL window — O(M*P) redundant
tokenization + row allocation. The Windows reader already caches parsed rows;
this makes the POSIX default reader do the same by parsing inside the deduped
scan and returning ProcessTableRow[]. Collapses the duplicate parsePsRows in
the main and relay foreground resolvers into one shared parseProcessTableRows.

* fix(emulator): remove destroyed listener on stream stop to stop webContents leak
Both emulator stream IPC handlers register owner.once('destroyed', ...) per
start but never remove it on stop. .once only self-removes when the event
fires (window close), so every emulator tab show/hide cycle leaked a closure
on the long-lived main-window webContents — ~11 cycles trips Node's
MaxListenersExceededWarning and the closures grow unbounded until the window
dies. Store the handler on the session/subscription and removeListener on stop.

* chore(emulator): trim why-comment to 2 lines, drop no-op afterEach
Review polish: honor AGENTS.md 1-2 line comment guidance and remove a
vi.clearAllTimers() that is a no-op without fake timers.

The empty-state copy chooser only handled idle PR-refresh statuses inside the
ambiguous-hosted-review guard. When a background PR refresh went active
(queued/in-flight) or errored, it fell through to the publish-branch branch and
rendered 'Branch not published' on a no-upstream branch. As the refresh cycled,
the panel flip-flopped between the two messages (most visible on Windows, where
local git latency widens the active window).
Resolve the whole empty state inside the ambiguous guard so the copy is stable
across the entire refresh lifecycle: 'error' -> 'Could not refresh pull request',
every other status -> 'Pull request status unavailable'. The ambiguous state can
no longer surface publish guidance.

Enable three unicorn rules — one correctness, two performance — and fix every
existing violation repo-wide so the rules pass as errors.
prefer-number-properties (76 sites)
- parseInt/parseFloat/NaN -> Number.* : safe aliases (autofixed).
- isNaN -> Number.isNaN (12 sites, hand-converted): global isNaN coerces its
argument, Number.isNaN does not. Verified every call site already passes a
number (Number.parseInt results, number-typed fields, Date.getTime()), so the
conversion is behavior-preserving today and guards against a future non-numeric
argument silently coercing.
prefer-array-find (26 sites)
- .filter(pred)[0] -> .find(pred); .filter(pred).at(-1) / .pop() -> .findLast(pred).
Drops the intermediate array and short-circuits.
prefer-array-index-of (5 sites)
- .findIndex(x => x === v) -> .indexOf(v).
Verified: typecheck (node/cli/web) clean, 53 affected suites pass (1679 tests),
oxlint clean repo-wide. mobile/ uses findLast safely (already ships ES2023
.toReversed()); config scripts and e2e helpers run on Node 24.
