+# Clide Claude-Code skills
+
+Skills are reusable instruction packs Claude Code loads on demand. Each one
+lives in its own directory with a `SKILL.md` (frontmatter + body) and any
+helper scripts. This index is for humans skimming what's available; Claude
+discovers skills automatically from the directory structure.
+
+| Skill | Purpose |
+|---|---|
+| [`d2-diagram`](d2-diagram/SKILL.md) | Generate technical diagrams from `.d2` source with the d2 CLI; renders to PNG. |
+| [`frame0-wireframe`](frame0-wireframe/SKILL.md) | Author UI wireframes as local JSON and sync to the Frame0 desktop app for rendering + export. |
+| [`git-commit`](git-commit/SKILL.md) | Commit conventions for this repo — message style, CHANGELOG discipline (40/60 word cap), attribution trailer, safety rules. |
+| [`pql`](pql/SKILL.md) | Query and plan against the markdown vault via the `pql` CLI (decisions, tickets, structural queries). |
+| [`skill-create`](skill-create/SKILL.md) | Guidance for creating new skills — SKILL.md structure, bundling scripts, packaging. |
+| [`testmode`](testmode/SKILL.md) | Run and interpret the `ClideTestApp` platform integration harness; smoke-test after toolchain / IPC / theme / native changes. |
+| [`ui-design`](ui-design/SKILL.md) | Visual design guide — surface tokens, control geometry, Phosphor icons. |
+| [`whats-next`](whats-next/SKILL.md) | Dependency-driven batch selection against the pql backlog. Walks the initiative/epic tree, filters unblocked work, refines, optionally activates. |
+
+## Adding a skill
+
+Use the `skill-create` skill (or follow its SKILL.md by hand). Add a row to
+the table above so the inventory stays accurate; the index is otherwise just
+a directory listing.
@@ -53,6 +53,35 @@ This repo follows [Keep a Changelog 1.1.0](https://keepachangelog.com/en/1.1.0/)

 Entries should be short imperative phrases that describe user-facing impact — not implementation detail. "Added sidecar PTY support for terminal pane" beats "Added `internal/pty/session.go`."

+### Be concise — this is the rule, not a suggestion
+
+CHANGELOG entries must be **one or two short sentences**. Hard cap: **60 words per bullet** (enforced by `ci/changelog_gate.sh`). Aim for 30 or under; if you can't say it in one line wrapped at ~75 columns, you're writing the wrong document.
+
+The CHANGELOG is read by humans scanning for what changed between two versions. It is **not** the place for the rationale, the probe results, the implementation detail, the behavior-change deep dive, or the "see also" cross-references. Those belong in:
+
+- the **commit message body** — explain *why*, list evidence, name the trade-offs;
+- a **D-record / decision document** — durable architectural rationale;
+- the **ticket / PR description** — work-context and review notes.
+
+Hard rules:
+
+- **No multi-paragraph bullets.** One paragraph max. If you reach for a blank line inside a bullet, stop and split or trim.
+- **No "Behavior change:" / "Side benefit:" / "Note:" sub-headers inside a bullet.** Those are essay structure; put them in the commit message.
+- **No probe numbers, latency stats, or %-coverage deltas in entries.** ("hit 95% target" is fine; "0 hangs in 300 spawns vs ~5% before" is commit-body material.)
+- **No nested function/file lists inside parentheses.** If you find yourself writing `(foo, bar, baz, …)` for more than 3 items, just say "several X" and trust the diff.
+- **Don't restate the title in the body.** A bullet is its own title.
+
+Calibration — match the **existing entries** in `CHANGELOG.md`. Open it, look at five recent bullets, write to that length. If your draft is visibly bigger than its neighbors, trim until it isn't.
+
+Good:
+> - Mouse wheel scrolling in Claude pane — converts scroll events to PgUp/PgDown so TUI apps scroll naturally.
+
+Bad (verbose; commit-body material leaked in):
+> - **PTY spawning switched from `forkpty()` to `posix_openpt()` + `posix_spawn()`** (T-96). `forkpty` calls `fork()` underneath, which is unsafe in the multithreaded Dart VM: about 5% of spawns deadlocked in the child before `execve` because libc locks held by ghost-threads remained "locked forever" in the forked child. `posix_spawn` uses `vfork` (glibc/musl/macOS), keeping the parent suspended until `execve` completes — no Dart code runs in the child. Probed: zero hangs in 300 sequential spawns vs ~5% before. **Behavior change:** missing executable / missing workingDirectory now surface as a `PtyException`…
+
+Better:
+> - PTY spawning uses `posix_openpt` + `posix_spawn` instead of `forkpty` — closes a ~5% deadlock window in the multithreaded Dart VM (T-96). Missing exe/cwd now throw `PtyException` at spawn time.
+
 **What skips the changelog:** pure bookkeeping commits that have no user-visible effect (typo fix in internal comment, `.gitignore` tweak, lint config change, reformatting). When in doubt, add an entry — the harm of an extra line is zero.

 When a commit spans multiple entries (e.g. a feature that adds one thing and fixes another), add a line under each applicable subsection rather than cramming both into one.

Probed: 2 hangs out of 30 sequential `/bin/sh -c "printf hello-pty"` spawns over a 30s/spawn timeout.
+
+**Symptom:** test sees zero `pane.output` events and no `pane.exit`; the reader isolate sits in `poll(pfd, 1, 100)` returning 0 forever. The hang is per-spawn; a fresh `NativePty.start` recovers cleanly.
+
+**Workaround in place:** `retry: 2` on every PTY-output-dependent test in `test/pty/session_test.dart` and `test/panes/registry_test.dart`. Three combined attempts at ~5% per-spawn fail rate ≈ 99.99% success. Comments at the test sites point back here.
+
+**Acceptance:**
+- Identify why a fresh master fd sometimes never delivers ready events. Candidates to investigate: a race between `forkpty()` and `Isolate.spawn` (the new isolate may see an FD table snapshot from an awkward moment), a missing fcntl flag on the master fd, lazy `DynamicLibrary.process()` symbol resolution in a freshly-spawned dart isolate, GC interference, or wasmtime/tree-sitter signal handlers (unlikely — the probe ran in a clean dart isolate with no wasmtime).
+- Fix the underlying race so a single spawn delivers reliably.
+- Remove the `retry: 2` decorations and the explanatory comments in both test files.
+
+**Out of scope:** changing the PTY threading model or the reader-isolate architecture. The fix should keep `Isolate.spawn(_readLoop, ...)` as the I/O primitive.
+
+**Cross-references:** D-5 (Dart core + sidecar dissolution; PTY is owned via FFI), `lib/src/pty/native_pty.dart#L235-262` (`_spawnReaderAsync`), `lib/src/pty/native_pty.dart#L265-293` (`_readLoop`).', 'The reader isolate spawned by `NativePty._spawnReaderAsync` (`lib/src/pty/native_pty.dart`) hangs intermittently — about 5% of fresh spawns — with poll() on the master fd never returning POLLIN or POLLHUP, even when the child has clearly written and exited. Probed: 2 hangs out of 30 sequential `/bin/sh -c "printf hello-pty"` spawns over a 30s/spawn timeout.
+
+**Root cause — found 2026-05-17 via forensic probe:**
+
+The "child" never reaches `execve`. `/proc/<child-pid>/stat` reports comm `(DartWorker)` (the Dart VM worker thread name) instead of `sh`, with state `S` (sleeping). The pty master fd is a real pty (tty-index assigned, fcntl flags 0x8002 = O_RDWR|O_NOCTTY), but `poll(fd, 500ms)` from the main isolate returns 0 — nothing was ever written.
+
+This is **`fork()` in a multithreaded process** — a textbook async-signal-safety violation. The Dart VM runs multiple worker threads that hold libc locks (notably `malloc`). When `forkpty()` calls `fork()`, only the calling thread survives in the child, but the locks held by ghost-threads remain "locked forever." The child deadlocks before it can complete its post-fork → pre-execve setup.
+
+Why not always? Lock state at fork() time is timing-dependent. ~95% of the time no Dart worker happens to hold a problematic lock, and execve proceeds. ~5% of the time it deadlocks.
+
+**Workaround in place (test-only):** `retry: 2` on every PTY-output-dependent test in `test/pty/session_test.dart` and `test/panes/registry_test.dart`. Three combined attempts at ~5% per-spawn fail rate ≈ 99.99% combined success. Comments at the test sites point back here.
+
+**Proper fix:** replace `forkpty()` with `posix_openpt()` + `unlockpt()` + `grantpt()` + `posix_spawn()` (with file actions wiring the pty slave to stdin/stdout/stderr). `posix_spawn` uses `vfork()` under glibc/musl, which keeps the parent suspended until execve completes — no Dart code ever runs in the child, no lock-deadlock possible. Linux and macOS both support this API.
+
+**Immediate hardening alternative (Linux-only, simpler):** after spawn, sample `/proc/<pid>/comm` after ~250ms. If it equals the parent process''s comm, execve never ran → kill the child, surface `PtyException(''execve-deadlock'', ...)`, let the caller retry. This catches the deadlocked state deterministically instead of waiting for a poll timeout. It doesn''t fix the bug, but turns silent hangs into reportable errors.
+
+**Acceptance for closing this ticket:**
+1. Replace forkpty path with posix_openpt + posix_spawn (or implement the comm-check hardening as an interim).
+2. Probe (200 sequential `printf hello`-and-exit spawns) reports zero hangs.
+3. Remove the `retry: 2` decorations + explanatory comments in `test/pty/session_test.dart` (6 tests) and `test/panes/registry_test.dart` (1 test).
+
+**Out of scope:** changing the reader-isolate architecture itself. `Isolate.spawn(_readLoop, ...)` for output stays.

+The consultant findings here — single root `KeyboardListener` will conflict with text-input fields; `KebindingResolver.fromKeyEvent` keys off layout-dependent `logicalKey.keyLabel` — are both addressed by the keystroke mapper layer (T-117):
+
+- Keymap-driven dispatch uses `LogicalKeyboardKey.keyId` (stable across layouts), not `keyLabel`.
+- Root `KeyboardListener` now hands events straight to `KeymapService.resolveEvent`, which dispatches resolved Intents via `Actions.maybeInvoke` against the focused context — Actions providers per feature (palette, editor, etc.) handle their own intents; the root only handles global ones (text scale, generic command bridge). This is the scoped Shortcuts/Actions model the consultant prescribed.
+
+Remaining cleanup (deletion of the now-vestigial `KeybindingResolver` class + the legacy `KeyboardListener` wrap once Flutter Shortcuts widget integration is on every feature) is small and lands as part of T-100 or its own follow-up.

Probed: 2 hangs out of 30 sequential `/bin/sh -c "printf hello-pty"` spawns over a 30s/spawn timeout.
+
+**Root cause — found 2026-05-17 via forensic probe:**
+
+The "child" never reaches `execve`. `/proc/<child-pid>/stat` reports comm `(DartWorker)` (the Dart VM worker thread name) instead of `sh`, with state `S` (sleeping). The pty master fd is a real pty (tty-index assigned, fcntl flags 0x8002 = O_RDWR|O_NOCTTY), but `poll(fd, 500ms)` from the main isolate returns 0 — nothing was ever written.
+
+This is **`fork()` in a multithreaded process** — a textbook async-signal-safety violation. The Dart VM runs multiple worker threads that hold libc locks (notably `malloc`). When `forkpty()` calls `fork()`, only the calling thread survives in the child, but the locks held by ghost-threads remain "locked forever." The child deadlocks before it can complete its post-fork → pre-execve setup.
+
+Why not always? Lock state at fork() time is timing-dependent. ~95% of the time no Dart worker happens to hold a problematic lock, and execve proceeds. ~5% of the time it deadlocks.
+
+**Workaround in place (test-only):** `retry: 2` on every PTY-output-dependent test in `test/pty/session_test.dart` and `test/panes/registry_test.dart`. Three combined attempts at ~5% per-spawn fail rate ≈ 99.99% combined success. Comments at the test sites point back here.
+
+**Proper fix:** replace `forkpty()` with `posix_openpt()` + `unlockpt()` + `grantpt()` + `posix_spawn()` (with file actions wiring the pty slave to stdin/stdout/stderr). `posix_spawn` uses `vfork()` under glibc/musl, which keeps the parent suspended until execve completes — no Dart code ever runs in the child, no lock-deadlock possible. Linux and macOS both support this API.
+
+**Immediate hardening alternative (Linux-only, simpler):** after spawn, sample `/proc/<pid>/comm` after ~250ms. If it equals the parent process''s comm, execve never ran → kill the child, surface `PtyException(''execve-deadlock'', ...)`, let the caller retry. This catches the deadlocked state deterministically instead of waiting for a poll timeout. It doesn''t fix the bug, but turns silent hangs into reportable errors.
+
+**Acceptance for closing this ticket:**
+1. Replace forkpty path with posix_openpt + posix_spawn (or implement the comm-check hardening as an interim).
+2. Probe (200 sequential `printf hello`-and-exit spawns) reports zero hangs.
+3. Remove the `retry: 2` decorations + explanatory comments in `test/pty/session_test.dart` (6 tests) and `test/panes/registry_test.dart` (1 test).

+- **Keys**: `LogicalKeyboardKey.keyId` (layout-independent, not the locale-aware keyLabel the consultant flagged) + modifier set.
+- **When-clauses**: VS-Code-style boolean expressions over a named context bag (`palette.open && !textInputFocused`). Tiny recursive-descent parser.
+- **Preset format**: YAML under `assets/keymaps/<preset>.yaml`. Ships `default.yaml`; vim/vscode/jetbrains land as separate tickets.
+- **Layering**: preset (asset) → user file (`~/.clide/keybindings.yaml`) → settings JSON overlay (`app.keymap.overrides`). Later layers replace bindings with the same (chord, when) tuple.
+- **Service**: `KeymapService` kernel service holding active layered keymap, scope context, resolver, and a Shortcuts/Actions wrapper.
+- **Settings keys**: `app.keymap.preset` (default `default`); `app.keymap.overrides` (list).
+
+## Acceptance
+
+1. `KeymapService` registered as a kernel service.
+2. `assets/keymaps/default.yaml` ships and parses; preset switching changes effective bindings.
+3. When-clause parser handles `a`, `!a`, `a && b`, `a || b`, parens, with unit tests covering precedence + identifier resolution.
+4. Root `KeyboardListener` in `app.dart` removed in favor of `Shortcuts`/`Actions` driven by the service (closes T-110).
+5. Existing `KeybindingResolver` callers migrate to the new path; old class either deleted or marked deprecated with a removal date.
+6. Tests: preset YAML round-trip, layering precedence, when-clause evaluator, scope-context updates, resolver picks the correct intent for chord+context.
+
+## Out of scope (deferred)
+
+- Vim/VSCode/JetBrains preset *data* (T-64/T-65/T-66 — this ticket lands the mechanism).
+- A settings UI for editing bindings (file editing + preset switching is enough for v1).
+- ClideTappable/Palette widget integration (T-100 — comes immediately after this lands).

No `Focus`, no Enter/Space handler, no focus ring. None of these widgets can be reached by Tab or activated from the keyboard. The keyboard-traversal test passes only because it externally wraps in a `Focus` node — it tests non-blocking, not operability.
+
+`ClidePalette` (`lib/widgets/src/clide_palette.dart`) is similarly broken: `onSubmitted` only ever invokes `filtered.first`; no up/down handling, no selected index, no selection highlight, no Escape handler.
+
+**Fix:**
+1. Wrap `ClideTappable`''s child in `Focus` + `Shortcuts`/`Actions` so Tab focuses it and Enter/Space invokes `onTap`. Render a focus ring via the token system.
+2. Add arrow-key navigation + selected-index + Escape + Enter-on-selected to `ClidePalette` (model after `_ProjectSwitcherDropdown.onKeyEvent` at `app.dart:446-452`).

+## [2.1.0] — 2026-05-18
+
+### Added
+
+- Contrast gate split — baseline `canonicalPairs` every theme passes,
+  strict `extendedPairs` (muted/status/syntax/focus-border) gated to
+  `-hc` / `-cb` variants. Ships `clide-hc`, `midnight-hc`, `paper-hc`,
+  `terminal-hc` siblings of the named themes (D-69, T-114, T-118).
+- Pre-push coverage gate — `make push-check` runs `ci/coverage_gate.sh`,
+  which fails if total line coverage drops below `coverage_floor:` in
+  `pubspec.yaml`. Floor ratchets up only; target 95% (D-66).
+- Pre-push changelog gate — `ci/changelog_gate.sh` fails on any
+  `## [Unreleased]` bullet over 60 words. Enforces the Keep-a-Changelog
+  conciseness rule in the git-commit skill.
+- Keymap layer (`KeymapService`) — typed Intents, YAML presets,
+  VS-Code-style when-clauses, layered preset → user file → settings
+  overlay. Default preset ships; vim/vscode/jetbrains unblocked
+  (T-117, supersedes T-110).
+- Keyboard operability — `ClideTappable` is now Tab-focusable with a
+  focus ring and Enter/Space activation; `ClidePalette` adds arrow
+  nav, Escape dismiss, and selection highlight (T-100).
+- Panel-to-panel focus traversal — each `SlotHost` wraps in a
+  `FocusScope` + `FocusTraversalGroup`; `F6` / `Shift+F6` cycle
+  sidebar → workspace → context. `FocusTracker` integrates with
+  Flutter focus rather than paralleling it (T-105).
+- Event-driven test waits — PTY + watcher tests await stream events
+  instead of fixed sleeps; `onTimeout` callbacks now `fail()` loudly
+  with diagnostic context. `RecordingEventSink` exposes a broadcast
+  stream for the same pattern (T-108).
+- Code-quality cleanups — `TreeSitterLib` exposes a last-error
+  diagnostic instead of swallowing dlopen failures; `ExtensionManager`
+  surfaces a `failedExtensions` map for UI degradation; PTY constants
+  consolidated in `libc.dart` + `PosixErrno`; `test_app.dart` gated
+  behind `kDebugMode` (T-112).
+- Test sweep — `keybindings`, `toolchain_paths`, and several
+  `widgets/src/` primitives (tooltip, palette, multitab, markdown).
+- `tree_sitter_service` sweep — fake-FFI + real-library smoke,
+  17% → 96%. Crosses the 95% global target (T-91).
+- Staged `dart doc` CI job — generates and uploads an HTML API
+  reference for the public `lib/` surface. The step wraps
+  `dart doc --validate-links` and grep-fails the build on any warning.
+  Inert with the rest of the workflow until Gitea Actions activates.
+- Mouse wheel scrolling in Claude pane — converts scroll events to
+  PgUp/PgDown so TUI apps scroll their history naturally.
+- Welcome screen Tips card — six common keybindings shown below the
+  START / RECENT row when the viewport is tall enough.
+- `MultitabPane` widget + `MultitabController` for panes that host
+  N runtime tab instances of the same kind. Generic over a payload
+  type, supports pinned/non-closeable tabs, drag-reorder, close × on
+  hover, and an optional `+` add button.
+- `MultitabPane.keepAlive` mode — entry bodies stay mounted via
+  IndexedStack so switching tabs preserves their state (PTY
+  connections, scroll position, etc.).
+- `CONTRIBUTING.md` — human-addressed contributor guide covering
+  clone / build / test / DQR / tickets / commit conventions. The
+  `[Unreleased]` section is reorganised to one subsection per kind
+  per Keep a Changelog 1.1.0 (T-109).
+- `make verify` — no-tests sweep (analyze + format + decisions +
+  changelog gate). For mid-edit checks; `make push-check` stays the
+  full pre-push pipeline.
+
+### Changed
+
+- Window-control close-button red, white close glyph, and palette
+  ambient shadow are now tokens (`windowControl.closeHover*`,
+  `shadow.ambient`) instead of hard-coded hex. Light themes get a
+  softer ink-tinted shadow (T-114).
+- Text-zoom (Ctrl +/-/0) is now a kernel `TextZoom` service and shows
+  up in the palette as `View: Zoom In/Out/Reset Zoom` (T-114).
+- Panel splitters (sidebar / context / editor-split) are tab-focusable;
+  arrow keys nudge by 10 px, Shift+arrow by 50 px (2% / 10% for the
+  editor split). Exposed as slider Semantics nodes so screen readers
+  announce the current size. CLI verb deferred to T-99 (T-111).
+- Changelog gate is binary — dropped the soft 40-word warning, kept
+  the 60-word hard cap. Warnings that never blocked just normalised
+  drift.
+- PTY spawning uses `posix_openpt` + `posix_spawn` instead of
+  `forkpty` — closes a ~5% deadlock window in the multithreaded Dart
+  VM (T-96, D-5 amended). Missing exe/cwd now throw `PtyException` at
+  spawn time. Drops the `libutil.so.1` dependency.
+- Coverage floor ratcheted to 95% — D-66 target hit.
+- `TreeSitterService` and `TreeSitterLib` accept injectable FFI + asset
+  loaders for fake-driven tests; production paths unchanged.
+- Tidied test imports flagged by `unnecessary_import`.
+- `README.md` rewritten to match current architecture;
+  `docs/initial-plan.md` bannered as historical; new
+  `docs/architecture.md` describes today's shape (T-101).
+- `SchedulerService._stopTicker` now awaits the in-flight isolate spawn
+  before killing — closes the same race shape we fixed in PTY (T-106).
+- `make push-check-full` added — runs `push-check` plus integration +
+  smoke for pre-release checks. Integration tests skip the hanging
+  theme_picker case until that's fixed (T-103, T-116).
+- Governance bookkeeping: D-66 amended (floor at `coverage_floor:` in
+  `pubspec.yaml`); `licenses.yaml` reconciled with `pubspec.yaml`;
+  Q-1/Q-2/Q-3/Q-25 triaged; `.claude/skills/README.md` inventory
+  added; `--no-fatal-infos` dropped from `ci/test.sh` (T-113).
+- Terminal panes render bold attributes with a real bold weight —
+  bundled JetBrainsMono Bold + BoldItalic registered with the
+  `JetBrainsMono` family at `weight: 700`. The painter's bold
+  suppression workaround is gone.
+- Claude pane uses `MultitabPane` for primary + secondaries — drops
+  ~100 lines of bespoke tab-strip code, gains drag-to-reorder.
+- UI spacing constants live in `lib/widgets/src/spacing.dart` —
+  `clideInset*` for paddings, `clideGap*` for sibling distances,
+  `clideIcon*` / `clideControlHeight` for control sizes.
+- Tagline reads "IDE for Claude Code CLI" everywhere (welcome
+  subtitle, README, CLAUDE.md, pubspec, web manifest, CLI banner).
+- Inline terminal emulator based on xterm.dart v4.0.0 — replaces the
+  pub.dev dependency with owned code under `lib/src/terminal/`. Drops
+  three transitive dependencies (xterm, quiver, zmodem).
+- Bundle clide-specific tmux.conf for Claude pane sessions: no status
+  bar, 50k scrollback, mouse on, zero escape delay, isolated socket.
+- Claude pane spawns `claude` directly inside tmux with
+  `CLAUDE_CODE_NO_FLICKER=1` to enable Claude's fullscreen TUI mode.
+- PTY read buffer increased from 4 KB to 64 KB.
+- Terminal view 2 px padding on all sides.

-  "Callback for when the user taps on the terminal" was a no-op
-  for every caller. Routes through `TerminalGestureHandler.onSingleTapUp`

 - `BufferLine.eraseRange` no longer panics when called with `end == 0`.

-  which threw a `RangeError`. Real trigger path: `Terminal.eraseDisplayAbove`
-  with the cursor at column 0 — common after `ESC[H\x1b[1J`

- Terminal selections no longer silently disappear when the terminal is
-  resized narrower. Reflow's tail-anchor handler used to reparent
-  anchors past the source's trimmed-content range onto a builder line
-  that was never emitted, leaving them detached from the visible
-  buffer; the selection controller's `extent.attached` check then
-  returned null and the highlight vanished. Common trigger paths:
-  Ctrl+A (select-all) followed by a width change, and mouse drag
-  selections that extended past the end of a partially-filled line
-  (T-92).

-  surfaced by unit tests added under T-91. Anchors disposed inside
-  the loop were unhooking themselves from the same list the loop was

+- IPC: `git.checkout`, `git.push` reject branch/remote args starting
+  with `-` (closes the `--upload-pack=...` argv-injection vector).
+  `files.read` rejects files over 10 MB. `git.log` caps `count` at
+  1000; `git.diff` / `git.stage` cap paths at 256 (T-104).
+- Toolchain no longer resolves the dugite git binary against the open
+  workspace — a malicious repo could plant `native/dugite/bin/git`
+  and clide would run it on auto-fired `git.status`. Dugite now
+  resolves against the install dir + `CLIDE_DUGITE_DIR` env override
+  only (T-98).

+# Contributing to clide
+
+clide is an IDE for the Claude Code CLI, built as a single Flutter
+package at the repo root. This guide is for people working on clide
+itself.
+
+For day-to-day model-driven work in the codebase, see
+[`CLAUDE.md`](CLAUDE.md) — it documents the same guardrails from the
+agent's point of view and is the place to look for "why is the code
+shaped like this?"
+
+## One-time setup
+
+```
+git clone git@github.com:postmeridiem/clide.git
+cd clide
+make hooks && flutter pub get
+```
+
+`make hooks` installs the repo's git hooks (pre-commit + post-merge).
+Flutter must be on the stable channel and on `$PATH`.
+
+If you haven't used [pql](https://github.com/postmeridiem/pql) before,
+install it and run `pql init` once in the repo root. pql is a hard
+dependency for the governance + ticket workflow described below.
+
+## The five commands you'll actually use
+
+```
+make run           # launch the desktop app
+make verify        # no-tests sweep — analyze + format + decisions + changelog gate
+make test          # fast suite — analyze + format + unit + widget + golden
+make test-a11y     # WCAG-AA contrast + keyboard traversal contracts
+make push-check    # the pre-push gate; what CI runs
+make build-linux   # release artefact for the host platform
+```
+
+`make verify` is the lightweight "are the gates green?" check for
+mid-edit iteration. `make push-check` is the full pre-push pipeline
+(verify + every test suite + coverage gate).
+
+`make` with no target prints the full list. `make test-integration`
+boots a real app process and is slow; reserve it for the rare change
+that touches startup wiring.
+
+The pre-push hook runs `make push-check` automatically. Don't bypass
+it with `--no-verify` — fix the underlying issue and create a new
+commit. Pre-push includes:
+
+- `flutter analyze` (zero warnings)
+- `dart format --set-exit-if-changed`
+- the fast unit/widget/golden suites
+- accessibility contract tests
+- a coverage floor read from `coverage_floor:` in `pubspec.yaml`

+clide tracks architectural commitments as durable records under
+[`governance/`](governance/):
+
+- `decisions/<domain>.md` — confirmed decisions (`D-NNN`)
+- `questions/<domain>.md` — open questions (`Q-NNN`)
+- `rejected/<domain>.md` — rejected proposals (`R-NNN`)
+
+When you make a non-trivial architectural choice, write it down:
+
+```
+pql decisions claim D <domain> "short title"
+```
+
+This reserves a fresh ID and tells you where to add the record. The
+[governance/README.md](governance/README.md) explains the format and
+the recommended domain list.
+
+Pre-push validates that every `D-NNN` / `Q-NNN` / `R-NNN` link in
+the docs and code resolves to an actual record (`pql decisions
+validate`). Broken references fail the build.
+
+## Tickets
+
+All non-trivial work is tracked in `pql ticket`:
+
+```
+pql ticket list --status in_progress
+pql ticket show T-NNN[,T-NNN…]      # batch form on pql 1.4.33+
+pql ticket new task "title" --parent T-NNN --priority medium
+pql ticket status T-NNN in_progress
+pql ticket status T-NNN done
+```
+
+A ticket exists for any change a reviewer might want to ask "why?"
+about. Bug fixes, refactors, and consultant findings all become
+tickets before the diff lands. Trivial typo fixes don't need one.
+
+## Commit conventions
+
+See [D-37](governance/decisions/process.md#d-37) and the bundled
+[`git-commit` skill](.claude/skills/git-commit/SKILL.md). In short:
+
+- Imperative subject ≤ 70 chars, no Conventional Commits prefix
+  (this isn't a Conventional Commits repo — the archived Python
+  predecessor under [`legacy/`](legacy/) is, but the rebuild isn't).
+- One logical change per commit. If the subject needs "and", split it.
+- Every user-visible commit adds an entry to `CHANGELOG.md` under
+  `[Unreleased]` in the right subsection (Added, Changed, Deprecated,
+  Removed, Fixed, Security). Keep entries to one or two short
+  sentences — the 60-word cap is enforced by `ci/changelog_gate.sh`.
+- Co-author trailer:
+  `Co-Authored-By: Claude <noreply@anthropic.com>` when Claude wrote
+  any of the diff.
+
+Never `--amend` a commit unless explicitly asked. Never force-push
+to `main`. Never `git add -A` / `git add .` when staging — name
+files explicitly so stray secrets or build artefacts don't sneak in.
+
+## Cutting a release
+
+A release is a single commit:
+
+1. Move all `## [Unreleased]` entries under a new `## [X.Y.Z] —
+   YYYY-MM-DD` heading.
+2. Leave an empty `## [Unreleased]` skeleton at the top.
+3. Bump `pubspec.yaml` `version:` to `X.Y.Z` (no `-dev` suffix on
+   the release tag; add it back on the next development commit if
+   you like).
+4. Commit subject: `release vX.Y.Z`.
+
+`pubspec.yaml` is the single source of truth for the version — the
+Makefile reads it for ldflag stamping and the app reads it for build
+info.
+
+## What goes where
+
+- **Bug, feature, sweep:** file/claim a ticket, branch, code, test,
+  commit, push. Push triggers `make push-check`.
+- **Architectural decision:** `pql decisions claim`, write the
+  record, then file the implementation ticket linked via
+  `decision_ref`.
+- **Open question:** drop a `Q-NNN` under
+  `governance/questions/<domain>.md`. Triage later.
+- **Rejected proposal:** drop an `R-NNN` under
+  `governance/rejected/<domain>.md`. Future-you (or a reviewer)
+  will be glad it's written down.

+# clide — External Consultant Review
+
+**Date:** 2026-05-14
+**Scope:** Full-repository assessment of clide at `main` (commit `9030e56`).
+**Method:** Six independent specialist reviewers, each given read-only access and a
+brief covering best practice, clean code, architecture, usability, stability,
+expandability, style, consistency, and general quality. Reviewers did not see each
+other's findings; cross-cutting themes below are genuine independent agreement.
+
+**Panel:**
+| Lens | Reviewer |
+|---|---|
+| Architecture | Software Architect |
+| Tests & quality gates | Test / QA Analyst |
+| UX & accessibility | UX & Accessibility Expert |
+| Code quality & craft | Senior Dart/Flutter Engineer |
+| Security & supply chain | Security Engineer |
+| Docs, governance & DX | TPM / Developer-Experience Consultant |
+
+---
+
+## Overall verdict
+
+clide is, for a solo-dev pre-v2.0 project, **unusually disciplined** — every reviewer
+said so independently. The governance system is alive, the core subsystems are small
+and well-typed, the FFI/PTY layer shows real systems-programming care, and the quality
+gates are genuine rather than ornamental. The codebase is in good shape.
+
+The weaknesses cluster into a handful of themes, and several are **load-bearing**: a
+central guardrail (CLI-first IPC) has no runtime implementation, keyboard operability —
+the core requirement of a power-user dev tool — is largely unbuilt, an untrusted
+workspace can achieve code execution, and the two primary onboarding documents describe
+an architecture that no longer exists.
+
+None of these are fatal; all are fixable; most have quick-win first steps. But they
+should be addressed before a public v2.0.
+
+---
+
+## Cross-cutting themes (independent agreement)
+
+These were each flagged by **two or more** reviewers who did not coordinate:
+
+1. **The IPC layer is mid-migration and contradicts itself.** The Architect found no
+   Unix-socket *server* anywhere in `lib/` — D-56's "app hosts an in-process IPC server"
+   and D-1's "CLI-first, not MCP" have no runtime path; three IPC clients
+   (`DaemonClient`, `InProcessClient`, `IsolateClient`) coexist with two duplicated
+   service-wiring sites. The Security reviewer independently noted `DaemonClient`'s
+   socket code is still live as an unvalidated attack surface. **Pick one IPC model,
+   implement or amend D-56, delete the other two.**
+
+2. **The "no pre-existing excuse / clean board" guardrail is being violated right now.**
+   `flutter analyze` reports 9 `unnecessary_import` issues in `test/`; `ci/test.sh` runs
+   analyze with `--no-fatal-infos`, which silently tolerates them. Flagged by the
+   Architect, Code Quality, and Test reviewers. The repo's own rules say fix-first.
+
+3. **`lib/src/terminal/` is in an undeclared middle state.** ~7k LOC forked from
+   xterm.dart, carrying commented-out `print`s, dangling TODOs, a 1137-line `parser.dart`,
+   and the only `invalid_use_of_protected_member` suppression in the repo. MEMORY says
+   "code under `lib/` is owned, not vendored" — so it must either be formally vendored
+   (frozen, documented, decision-recorded) or cleaned to the project bar. Flagged by
+   Code Quality; the Architect's "consistency" deduction points at the same seam.
+
+4. **Documentation describes a dissolved architecture.** `README.md` and
+   `docs/initial-plan.md` still describe a Go sidecar, `ptyc/` C helper, `app/`
+   subdirectory, and a separate `clide --daemon` process — all removed by D-5, D-56, and
+   the FFI pivot. A new contributor's first read builds a wrong mental model.
+
+---
+
+## Consolidated scorecard
+
+Scores are each reviewer's, 1–5, on their own dimensions.
+
+| Domain | Dimension | Score |
+|---|---|---|
+| **Architecture** | Layering & dependency direction | 4 |
+| | Separation of concerns | 4 |
+| | Expandability | 5 |
+| | Consistency | 4 |
+| | Guardrail adherence | 3 |
+| **Tests** | Coverage quality | 4 |
+| | Test reliability / flakiness | 3 |
+| | Gate trustworthiness | 3 |
+| | Test maintainability | 5 |
+| | Regression-catching power | 4 |
+| **UX / a11y** | Interaction model | 2 |
+| | Accessibility | 3 |
+| | Visual consistency | 4 |
+| | Discoverability | 2 |
+| | State coverage (loading/error/empty) | 3 |
+| **Code quality** | Idiomatic Dart | 4 |
+| | Error handling | 4 |
+| | Naming & readability | 4 |
+| | Consistency across subsystems | 3 |
+| | Resource / lifecycle safety | 4 |
+| **Security** | Subprocess safety | 2 |
+| | IPC input validation | 3 |
+| | Path / filesystem safety | 3 |
+| | Dependency / supply-chain hygiene | 3 |
+| | Secrets & sandboxing | 3 |
+| **Docs / governance** | Governance discipline | 4 |
+| | Documentation accuracy | 2 |
+| | Changelog hygiene | 3 |
+| | Contributor onboarding | 2 |
+| | Convention adherence | 4 |
+
+**Highest marks:** expandability (5), test maintainability (5). The extension contract
+and test-helper design are genuine standouts.
+**Lowest marks:** interaction model (2), discoverability (2), subprocess safety (2),
+documentation accuracy (2), contributor onboarding (2).
+

+
+## Prioritized action list
+
+Synthesized across all six reviews. Severity is the highest any reviewer assigned.
+
+### Critical — address before public v2.0
+
+1. **Fix untrusted-workspace code execution.** `toolchain_paths.dart:79` resolves
+   `native/dugite/bin/git` relative to the *workspace root*; a malicious repo can plant
+   an executable there that clide runs on the first auto-fired `git.status`. Resolve
+   `native/dugite` against `Platform.resolvedExecutable`'s directory, never the
+   workspace. *(Security)*
+2. **Resolve the IPC story.** Either implement the in-process Unix-socket server per
+   D-56 so the `clide` CLI / C client actually works, or amend D-56 to make in-process
+   direct dispatch the design and delete `DaemonClient`'s socket code, `IsolateClient`,
+   `Backend`, and `backend_entry.dart`. Today the code claims three models and runs one,
+   and a load-bearing guardrail (D-1/D-6) is unmet. *(Architecture, Security)*
+3. **Make the tool keyboard-operable.** `ClideTappable` (base of nearly every
+   interactive widget) is mouse-only — no `Focus`, no Enter/Space. The command palette
+   has no arrow-key navigation and no Escape. For a keyboard-first dev tool this is a
+   functional gap, not a polish item. *(UX)*
+4. **Fix the onboarding docs.** Rewrite `README.md`'s `ptyc/` / `make ptyc-build`
+   sections, fix its dead `decisions/` link, and banner `docs/initial-plan.md` as
+   historical (or split out a current `docs/architecture.md`). *(Docs)*
+
+### Major — should land soon
+
+5. Add symlink re-resolution + containment re-check in `files.read` / `files.ls` — a
+   repo symlink `config -> /etc/shadow` currently passes path-safety. *(Security)*
+6. Add `test-integration` (and ideally `smoke-bundle`) to `make push-check` — the gate
+   that catches "app won't boot" is currently omitted from the pre-push gate. *(Tests)*
+7. Schema-validate the IPC argument surface; reject `-`-prefixed `branch`/`remote`/`path`
+   values; add size/count bounds. *(Security)*
+8. Establish a real focus-traversal model (`FocusTraversalGroup` per slot, a documented
+   "focus next panel" keybinding) and integrate `FocusTracker` with Flutter's focus
+   system instead of paralleling it. *(UX)*
+9. Fix the `SchedulerService._startTicker` isolate-spawn race — a `_stopTicker()` before
+   the spawn future resolves leaks a forever-ticking isolate. Mirror `NativePty`'s
+   `_readerReady` pattern. *(Code quality)*
+10. Decide the status of `lib/src/terminal/` — formally vendor (and decision-record) it,
+    or do the cleanup sweep. *(Code quality)*
+11. Replace fixed wall-clock `Future.delayed` sleeps in `watcher_test.dart` /
+    `session_test.dart` with event-driven waits; make swallowed `onTimeout` callbacks
+    `fail()` loudly. *(Tests)*
+12. Write a human-facing `CONTRIBUTING.md`; cut an interim release to drain the ~80-commit
+    `[Unreleased]` backlog; merge duplicate changelog subsection headings. *(Docs)*
+13. Single global `KeyboardListener` → scoped `Shortcuts`/`Actions`; move
+    `KeybindingResolver` off layout-dependent `keyLabel`. *(UX)*
+
+### Quick wins — hours each

+## 1. Architecture — Software Architect
+
+### Executive summary
+
+clide is an unusually disciplined solo-dev codebase. The governance system (67
+D-records, tracked Q/R) is real and largely honored in code, the kernel/extension split
+is coherent, and the feature-first layout with barrel files is consistently applied. The
+single biggest strength is the **extension contract**: every built-in — including layout
+itself — passes the same `ClideExtension` + `ContributionPoint` contract, which is the
+best possible proof the contract is usable. The single biggest risk is **architectural
+drift in the IPC layer**: D-56 mandates the Flutter app host an in-process IPC server
+reachable by a thin C client over a unix socket, but no socket server exists anywhere in
+`lib/` — the "CLI-first, not MCP" guardrail (D-1) has no runtime path today. Compounding
+this, three parallel IPC client implementations (`DaemonClient` socket,
+`InProcessClient`, `IsolateClient` + `Backend`) coexist with two competing
+service-wiring sites (`main.dart` and `backend_entry.dart`), suggesting an unfinished
+migration.
+
+### Strengths
+
+- **Extension contract is clean and scales** — `lib/extension/src/extension.dart` +
+  `contribution.dart`: sealed `ContributionPoint` hierarchy, `ClideExtensionContext`
+  lists services explicitly (deliberately avoiding a `KernelServices` import cycle —
+  `extension.dart:50-52`). `ExtensionManager` does dependency topo-sort,
+  dependency-gated activation, and contribution apply/remove symmetrically
+  (`extensions_manager.dart:164-202`). Adding a pane = new extension file + one
+  `register()` line in `main.dart`.
+- **Kernel admission rule is enforced, not aspirational** — D-12's "mandatory shared
+  singleton" test visibly shaped `KernelServices` (`facade.dart:38-93`); ~25 services,
+  each defensibly cross-cutting. The two-tier disable model (D-14) is honored:
+  `default_layout` is itself an extension.
+- **Feature-first layout with barrel discipline** (D-8) is consistent — every
+  `builtin/<name>/` and `kernel/` has a barrel; builtins import
+  `package:clide/kernel/kernel.dart`, not deep paths. Only one leak found.
+- **Governance-to-code traceability is genuine** — `WidgetsApp` root (D-7) at
+  `app.dart:38`, `ChangeNotifier`/`ListenableBuilder` state (D-10) everywhere, git
+  hardcoded in toolchain/project loader (D-13), terminal correctly tagged
+  `inlined-source` in `licenses.yaml` with modifications documented.
+- **Git subsystem cohesion** — `lib/src/git/` cleanly split into `client` / `status` /
+  `diff` / `operations` (~250 lines each), each a single responsibility.
+
+### Findings
+
+- **[Critical] No IPC socket server exists** — D-56 specifies the app hosts an
+  in-process IPC server with a C client connecting over a unix socket. `grep` for
+  `ServerSocket`/unix-domain `bind` in `lib/` returns nothing. `DaemonClient._connect`
+  (`client.dart:72-94`) *connects* to a socket, but nothing *serves* one. Today the only
+  working path is `InProcessClient` (`in_process.dart`), which calls the dispatcher
+  directly in-process. **Claude cannot drive clide via `clide ...` — the CLI-first
+  guardrail (D-1, D-6) has no implementation.** This is the load-bearing contract of the
+  whole project and it is absent.
+- **[Major] Three IPC clients + two wiring sites = unfinished migration** —
+  `DaemonClient` (socket), `InProcessClient`, and `IsolateClient`+`Backend`/
+  `backend_entry.dart` all coexist. `main.dart:76-113` wires subsystems via
+  `buildDispatcher`; `backend_entry.dart:40-110` wires the *same* five subsystems again
+  inside an isolate. `Backend.spawn` is referenced only by `facade.dart` but `main.dart`
+  uses `autoStartDaemonClient: false` + `daemonClientFactory` (the in-process path).
+  Dead-or-dormant isolate infrastructure with duplicated registration logic — pick one
+  and delete the others.
+- **[Major] `main.dart` (production entry) imports `test_app.dart`** — `main.dart:2` and
+  `:51-55`. The production binary carries the test harness and branches on
+  `CLIDE_TESTMODE`. Test scaffolding should not be reachable from the shipping entry
+  point; gate it behind a separate entrypoint or `kDebugMode`.
+- **[Minor] `flutter analyze` reports 9 issues** — all `unnecessary_import` in `test/`,
+  but CLAUDE.md's "no pre-existing excuse" / "clean board" guardrail makes this a
+  fix-first item.
+- **[Minor] Barrel leak** — `lib/builtin/files/src/file_tree_view.dart:8` imports
+  `package:clide/src/files/listing.dart` directly instead of via
+  `package:clide/clide.dart` (which already re-exports `FileEntry`).
+- **[Minor] `clide.dart` barrel exports the daemon dispatcher** — `clide.dart:15`
+  exports `src/daemon/dispatcher.dart`. The barrel is described as "shared types"; the
+  dispatcher is server-side machinery.
+- **[Minor] `ExtensionManager.activate` swallows exceptions** (`extensions_manager.dart:
+  141-143`) — a failed `activate()` logs and continues, leaving the extension
+  un-activated but `_known`, with no surfaced "degraded" state for the UI.
+
+### Recommendations
+
+**Quick wins:** clear the 9 analyzer issues; fix the `file_tree_view.dart` barrel leak
+(consider a CI grep gate for `package:clide/src/` imports outside their feature); move
+`test_app.dart` out of the production import graph; drop the `dispatcher.dart` export
+from `clide.dart`.
+
+**Larger efforts:** resolve the IPC story (implement the socket server per D-56, or
+amend D-56 and delete `DaemonClient`/`IsolateClient`/`Backend`/`backend_entry.dart`);
+collapse subsystem wiring into one `registerAllSubsystems(...)` function; give
+`ExtensionManager` a surfaced failure state so the UI can show degraded built-ins.
+
+### Scorecard
+
+| Dimension | Score | Justification |
+|---|---|---|
+| Layering & dependency direction | 4/5 | Kernel→extension direction clean, context-vs-aggregate split avoids cycles; docked for the `src/`↔`kernel/src/` barrel leak and the dispatcher export. |
+| Separation of concerns | 4/5 | Feature-first layout, single-responsibility subsystems; duplicated subsystem registration is the blemish. |
+| Expandability | 5/5 | New pane = one extension file + one `register()` line; sealed contribution hierarchy; layout itself is data and extension-shaped. |
+| Consistency | 4/5 | Barrels, naming, D-record back-references uniform; three coexisting IPC clients and 9 analyzer issues break the bar. |
+| Guardrail adherence | 3/5 | `WidgetsApp`, single-process, no-Material, governance, zero-deps all honored — but D-1/D-6/D-56 (CLI-first via socket server) have no runtime implementation. |

+
+## 2. Tests & quality gates — Test / QA Analyst
+
+### Executive summary
+
+The clide test suite is, for a solo-dev pre-2.0 project, in genuinely good shape. ~104
+test files against 276 lib files, ~92.75% line coverage, and — critically — the coverage
+was *not* bought with assertion-free filler. Even the alarmingly-named files
+(`coverage_trivials_test.dart`, `zero_coverage_widgets_test.dart`,
+`services_stubs_test.dart`, `mop_up_test.dart`) contain real behavioral assertions. The
+biggest strength is a sensibly layered pyramid with a real boot-path integration gate
+and a startup smoke test that catches the "tests pass but app won't launch" class. The
+biggest risk is **flakiness from wall-clock-dependent tests** — fixed `Future.delayed`
+sleeps in file-watcher and PTY tests will eventually produce intermittent CI failures,
+and the PTY tests are run via `dart test` so they are **excluded from the coverage
+measurement entirely**.
+
+### Strengths
+
+- **Test pyramid is sound.** Pure-Dart unit, widget tests with a shared harness, golden
+  tests (Alchemist), an a11y contract layer, and 3 real-boot `integration_test/` files —
+  correctly separated by runner (`ci/test.sh` vs `ci/test_core.sh` vs
+  `ci/test_integration.sh`).
+- **Helpers are well-designed.** `test/helpers/kernel_fixture.dart` boots a real
+  `KernelServices` with in-memory themes/i18n and `autoStartDaemonClient: false` — no
+  real socket, temp-dir scoped, proper `dispose()`. `FakeDaemonClient` is a clean stub.
+- **Error-branch discipline.** `pql_commands_errors_test.dart` /
+  `git_commands_errors_test.dart` deliberately point the toolchain at a non-existent
+  binary to drive catch-branches the happy path can't reach — table-driven, with
+  `reason:` tags.
+- **OS-dialog avoidance is handled correctly.** `welcome/dialog_test.dart` mocks the
+  `clide/window` MethodChannel to throw `MissingPluginException`, exercising the fallback
+  path *without* spawning a native file picker.
+- **Startup gate.** `ci/smoke_bundle.sh` builds the real release bundle and runs it
+  under xvfb for 5s, correctly interpreting `timeout` exit codes (124/143 = healthy).
+- **Coverage gate is honest.** `ci/coverage_gate.sh` is a self-contained awk parser (no
+  `lcov` dependency), ratchets only upward, and `exit 2` distinguishes "missing data"
+  from "below floor."
+
+### Findings
+
+- **[Major] PTY tests are excluded from coverage.** `ci/test.sh:13` runs
+  `flutter test --coverage --exclude-tags forkpty`; the `forkpty` tests run separately
+  via `dart test` with no `--coverage`. So `lib/src/pty/native_pty.dart` — the
+  highest-risk native code in the repo — is barely in the measured denominator. The
+  92.75% number overstates coverage of the riskiest file.
+- **[Major] Wall-clock sleeps will flake.** `test/files/watcher_test.dart:67-82` uses
+  fixed `Future.delayed`; `test/pty/session_test.dart:71` polls 50×100ms and `:65` uses a
+  bare `500ms` settle. `session_test.dart`'s `timeout(5s, onTimeout: () {})` (`:48`)
+  *swallows* the timeout — a never-producing PTY proceeds to a confusing assertion
+  failure rather than a clear timeout.
+- **[Major] `make push-check` does not run integration tests.** `push-check:
+  decisions-validate test-core test test-a11y coverage-gate` — `test-integration` and
+  `smoke-bundle` are omitted. A boot-order regression sails through.
+- **[Minor] `flutter analyze --no-fatal-infos` in `ci/test.sh:9`** contradicts the
+  stated "fail-on-warning, clean board" discipline.
+- **[Minor] Integration tests run one-file-at-a-time** to dodge a batch "Unable to start
+  the app" error — each invocation re-boots the engine (slow), and the workaround masks
+  whether the batch failure is environmental or a real teardown leak.
+- **[Minor] Golden CI config disabled.** Only platform goldens run; a Linux-only CI
+  never validates the macOS goldens, and stale `test/goldens/failures/*.png` artifacts
+  are committed to the repo.
+- **[Minor] `test_core.sh` timeout kill is best-effort** — the `pkill -9 -f` pattern
+  match is redundant noise next to the real `setsid` + `timeout --kill-after` safety net.
+- **[Minor] `git/client_test.dart` depends on the ambient `git` binary**, not the
+  vendored dugite — the suite passes/fails on the host git version.
+
+### Recommendations
+
+**Quick wins:** add `test-integration` (and `smoke-bundle`) to `push-check` — the single
+highest-value change; run the `forkpty` tests with `--coverage`; drop `--no-fatal-infos`;
+gitignore `test/goldens/failures/`; make `onTimeout` callbacks `fail()`.
+
+**Larger efforts:** replace fixed sleeps with event-driven waits
+(`expectLater(stream, emits(...))`); add a macOS golden CI matrix entry or document
+goldens as advisory; consider a coverage-exclusion allowlist for genuinely-unreachable
+defensive branches rather than chasing the last lines with filler tests.
+
+### Scorecard
+
+| Dimension | Score | Justification |
+|---|---|---|
+| Coverage quality | 4/5 | Tests are meaningful even in "mop-up" files; docked because PTY/FFI is outside the measured number. |
+| Test reliability / flakiness | 3/5 | Fixed wall-clock sleeps and a swallowed timeout are latent intermittent failures. |
+| Gate trustworthiness | 3/5 | Coverage gate and smoke bundle are well-built, but `push-check` omits integration tests. |
+| Test maintainability | 5/5 | Shared fixtures, consistent structure, table-driven error suites, clear doc comments. |
+| Regression-catching power | 4/5 | Real boot-path integration + smoke + a11y + goldens; weakened by single-OS goldens and PTY coverage gaps. |

+## 3. UX & accessibility — UX & Accessibility Expert
+
+### Executive summary
+
+clide has an unusually disciplined *foundation* for a solo pre-v2.0 project: a coherent
+semantic design-token system, a WCAG-AA contrast gate wired into CI, and i18n/semantic
+contract tests. That foundation is the biggest strength. The biggest risk is that
+**keyboard operability is largely unimplemented below the foundation** — the project's
+own core interaction primitive (`ClideTappable`) is mouse-only, the command palette has
+no arrow-key navigation or Escape, and there is no focus-traversal wiring across panels.
+For a keyboard-first power-user dev tool, this is a critical gap that the a11y test suite
+does not catch because the tests assert *structural* presence (Semantics nodes exist)
+rather than *operability* (can you actually drive it from the keyboard).
+
+### Strengths
+
+- **Semantic token system is real and enforced.** `lib/kernel/src/theme/tokens.dart`
+  defines ~65 named surface tokens; widgets consume `ClideTheme.of(context).surface`
+  rather than raw colors. The resolver provides defaults so partial themes still produce
+  a complete `SurfaceTokens`.
+- **Contrast gate is genuine WCAG math, run per-theme.** `lib/kernel/src/theme/
+  contrast.dart` implements real relative-luminance ratio with alpha pre-compositing
+  against neutral grey (`contrast.dart:31-37`) — semi-transparent tokens can't spuriously
+  pass.
+- **Semantics are present on composed widgets.** `ClideButton` wraps
+  `Semantics(button: true, enabled:, label:, hint:, onTap:)`; panels set
+  `container: true, explicitChildNodes: true` with landmark labels.
+- **State coverage exists in data panels.** `git_panel_view.dart:86-104` handles error,
+  loading, and empty ("working tree clean") states distinctly; `file_tree_view.dart`
+  handles error + loading.
+- **Manual a11y discipline is documented.** `docs/testing/a11y-manual.md` prescribes a
+  per-tier Orca/VoiceOver pass and is honest about why prose quality can't be automated.
+- **Disabled state is handled at the cursor level.** `clide_button.dart:41` switches to
+  `SystemMouseCursors.forbidden` and drops the semantic `onTap` when `onPressed == null`.
+
+### Findings
+
+- **[Critical] `ClideTappable` is mouse-only — no `Focus`, no keyboard activation.**
+  `lib/widgets/src/clide_tappable.dart:37-54` is `MouseRegion` + `GestureDetector` only.
+  It is the base for `ClideButton`, `_WinBtn`, `_RecentProjectRow`, `_ActionRow`, and
+  most builtin list items. None can receive Tab focus or be activated with Enter/Space.
+  The keyboard-traversal test only passes because it manually wraps the button in an
+  external `Focus` node — it tests that the widget doesn't *block* focus, not that it
+  *accepts* it.
+- **[Critical] Command palette is not keyboard-navigable.** `clide_palette.dart` —
+  `onSubmitted` only ever invokes `filtered.first` (`:77-80`); no up/down handling, no
+  selected index, no selection highlight, no Escape handler.
+- **[Major] No focus-traversal wiring between panels.** `FocusTracker`
+  (`lib/kernel/src/focus.dart`) tracks an active *contribution id* for the `clide active`
+  CLI, but is not Flutter `FocusScope`/`FocusTraversalGroup` integration. Nothing
+  establishes Tab order across sidebar → workspace → context.
+- **[Major] Drag-resize handles have no keyboard equivalent — parity gap.**
+  `drag_resize.dart` and `app.dart:870-912` are pure `Listener` pointer handlers, with no
+  Semantics node at all. Per "User/Claude parity", panel sizing should have a CLI
+  affordance; none is evident.
+- **[Major] Single global `KeyboardListener` is a fragile keybinding architecture.**
+  `app.dart:90-148` routes all shortcuts through one root `KeyboardListener` — no
+  per-context scoping, will conflict with text-input fields.
+  `KeybindingResolver.fromKeyEvent` keys off layout-dependent `logicalKey.keyLabel`.
+- **[Major] Text scale is the *only* in-app a11y accommodation, and it's hidden.**
+  `app.dart:122-138` implements Ctrl +/-/0 text scaling but it's undiscoverable. No
+  high-contrast toggle, no reduced-motion handling, no focus-ring rendering anywhere.
+- **[Minor] Contrast gate covers only 11 token pairs** — omits `globalTextMuted` (muted
+  text is everywhere), the `status*` foregrounds, syntax tokens on `panelBackground`, and
+  `panelActiveBorder`.
+- **[Minor] ~43 hardcoded-color sites bypass the token system** — some defensible (ANSI
+  palette), but the modal/palette shadow and window-control colors won't adapt to the
+  `paper` light theme.
+- **[Minor] Hover state is inconsistent and not paired with focus** — every interactive
+  widget reimplements its own `_hover` bool; none render a focus indicator.
+- **[Minor] `_LeftHatContent` is dead code** — `app.dart:281-292` always returns
+  `SizedBox.shrink()`.
+
+### Recommendations
+
+**Quick wins:** add a `Focus` + `Actions`/`Shortcuts` (Enter/Space → onTap) wrapper and
+a focus-ring inside `ClideTappable` — fixes the [Critical] for every button/list-item at
+once; add arrow-key + Escape + selected-index to `ClidePalette` (copy the existing
+`_ProjectSwitcherDropdown` `onKeyEvent` pattern at `app.dart:446-452`); expand
+`canonicalPairs`; surface text-zoom and theme switching in the palette; tokenize the
+modal shadow and window-control colors.
+
+**Larger efforts:** establish a real focus-traversal model and integrate `FocusTracker`
+with Flutter's focus system; replace the root `KeyboardListener` with scoped
+`Shortcuts`/`Actions` and move off `keyLabel`; add keyboard operability + Semantics to
+drag-resize handles plus a `clide panel resize` CLI; add an a11y test tier that asserts
+*operability*, not just Semantics presence.
+
+### Scorecard
+
+| Dimension | Score | Justification |
+|---|---|---|
+| Interaction model | 2/5 | Coherent slot/panel structure and good drag-resize *with a mouse*, but keyboard operability is largely unbuilt. |
+| Accessibility | 3/5 | Genuine contrast gate, Semantics on composed widgets, i18n contract tests — but keyboard operability and focus order are not implemented. |
+| Visual consistency | 4/5 | Strong semantic token system consumed consistently; a few hardcoded-color sites are real theme-adaptation bugs. |
+| Discoverability | 2/5 | Command palette isn't keyboard-navigable; accommodations are undiscoverable; no in-app keybinding reference. |
+| State coverage | 3/5 | Data panels and dialogs handle loading/error/empty; but no focus states anywhere and no reduced-motion handling. |

+
+## 4. Code quality & craft — Senior Dart/Flutter Engineer
+
+### Executive summary
+
+clide is, for a solo pre-v2.0 project, in genuinely good shape. The core subsystems (IPC
+envelope, daemon dispatch, git client, PTY) are small, single-responsibility,
+well-typed, and consistent. `flutter analyze` is clean for `lib/` — the 9 reported issues
+are all in `test/`, none are suppressions. The biggest strength is the FFI/PTY layer:
+`lib/src/pty/native_pty.dart` shows real systems-programming discipline (pre-fork
+allocation, errno captured before `free`, isolate-teardown ordering documented and
+correct). The biggest risk is concentrated in two places: a genuine isolate-leak race in
+`SchedulerService`, and the large vendored-but-owned `lib/src/terminal/` xterm.dart fork
+(~7k LOC) which carries a different style, commented-out `print`s, and dangling TODOs
+that the project's own "lib is owned, not vendored" rule says must be held to the same
+bar.
+
+### Strengths
+
+- **PTY/FFI layer is excellent.** `native_pty.dart:129-145` force-resolves FFI
+  trampolines and pre-allocates *all* native memory before `forkpty()`.
+  `native_pty.dart:171-177` captures `errno` before `_freeAll` because `free()` can
+  clobber it. `close()` (367-397) documents and implements the kill→EOF→close ordering
+  to avoid fd-reuse races. The child branch touches no Dart heap.
+- **IPC envelope is clean and idiomatic** — `lib/src/ipc/envelope.dart` uses a `sealed`
+  class hierarchy, named constructors, a private unifying constructor, and conditional
+  map keys. Decode is total over the type discriminant.
+- **Typed, meaningful errors.** `PtyException` carries `op` + optional `errno`;
+  `GitException` carries `stderr`; `errnoToIpcError` maps POSIX errno to actionable IPC
+  error kinds. Errors are values, not strings.
+- **Resource lifecycle is taken seriously across most subsystems.** `FileWatcher.stop()`
+  cancels the subscription *and* closes the controller; `withBuffer`/`setWinsize` in
+  `libc.dart` use `try/finally` around every native allocation. 45 files define
+  `dispose`/`close`.
+- **The `DaemonEventSink` interface** keeps the dependency graph pointing the right way
+  (server→subsystems) and is documented as such.
+- **The one `ignore_for_file` (`libc.dart:11-27`) is exemplary** — textbook FFI case,
+  multi-paragraph justification exactly as CLAUDE.md requires.
+
+### Findings
+
+- **[Major] Isolate-leak race in `SchedulerService._startTicker`** — `scheduler.dart:71`:
+  `Isolate.spawn(...).then((iso) => _isolate = iso)`. If `_stopTicker()` runs before the
+  spawn future completes, `_isolate` is still null, nothing is killed, and the
+  just-spawned isolate (with its `Timer.periodic`) leaks. `native_pty.dart` solved
+  exactly this with `_readerReady`.
+- **[Major] `lib/src/terminal/` held below the project's own bar.** Carries
+  commented-out `print()` debugging (`custom_text_edit.dart:244-275`), dangling TODOs
+  (`parser.dart:110-113`, `keytab.dart:91`), a 1137-line `parser.dart`, and the only
+  `// ignore: invalid_use_of_protected_member` in the repo (`terminal_view.dart:363`).
+  Either it's genuinely vendored (belongs in `native/` or documented as frozen) or it's
+  owned (needs the cleanup pass).
+- **[Minor] Empty `catch (_) {}` swallows in `tree_sitter_ffi.dart:197,206`** —
+  `DynamicLibrary.open` failures silently discarded; caller gets a bare `null` with no
+  diagnostic about *why*. Syntax highlighting silently not working is a support
+  headache.
+- **[Minor] Empty `catch (_) {}` in `test_app.dart:271,311`** — `:271` swallows a
+  theme-load failure the harness exists to detect.
+- **[Minor] Dead alias in `libc.dart:201-202`** — `typedef Cmsghdr = CmsghdrLinux;`
+  flagged "backward compatibility"; CLAUDE.md forbids backwards-compat hacks in a solo
+  repo.
+- **[Minor] `// ignore: unused_field` in `editor_controller.dart:25`** "kept for future
+  subscription changes" — speculative retention; the no-suppression rule wants it fixed,
+  not silenced.
+- **[Minor] Magic numbers in hot FFI paths.** `native_pty.dart` inlines `0x0001
+  // POLLIN`, `28 /* SIGWINCH */`, `4 /* EINTR */`, `9 /* EBADF */` — but `libc.dart`
+  already has a constants section and `errno_mapping.dart` has `PosixErrno.ebadf`.
+- **[Minor] `git_commands.dart` has ~16 near-identical handler bodies** — a
+  `_guarded(req, () async {...})` helper would remove ~60 lines of structural
+  duplication. Borderline.
+
+### Recommendations
+
+**Quick wins:** fix the `SchedulerService` spawn race (track the spawn future like
+`NativePty._readerReady`); replace the three silent `catch (_)` in `tree_sitter_ffi.dart`
+with a logged last-error; delete the `Cmsghdr` alias and the `unused_field` suppression;
+have the PTY layer consume `libc.dart` constants / `PosixErrno` instead of inline hex.
+
+**Larger efforts:** decide the status of `lib/src/terminal/` — formally vendor it
+(freeze, document, decision-record) or do the cleanup sweep; optionally a `_guarded`
+helper for `git_commands.dart` (check whether `files_commands` / `editor_commands` share
+the shape).
+
+### Scorecard
+
+| Dimension | Score | Justification |
+|---|---|---|
+| Idiomatic Dart | 4/5 | Sealed classes, named ctors, records, `const`, immutability used well; the vendored terminal tree pulls the average down. |
+| Error handling | 4/5 | Typed errors with context everywhere in core; a few silent `catch (_)` in the FFI loader and test harness cost the 5th point. |
+| Naming & readability | 4/5 | Clear, intention-revealing names; comments earn their place; inline magic numbers are the main blemish. |
+| Consistency across subsystems | 3/5 | IPC/git/files/pty are uniform; `lib/src/terminal/` is a different codebase in style; PTY duplicates constants `libc.dart` owns. |
+| Resource/lifecycle safety | 4/5 | `try/finally` around native allocs, controllers closed, subscriptions cancelled; the one real defect is the `SchedulerService` race. |
+
+---
+
+## 5. Security & supply chain — Security Engineer
+
+### Executive summary
+
+clide's security posture is **above average for a solo pre-v2.0 project**. All
+subprocess calls use `Process.run`/`Process.start` with argument *lists* (no shell
+interpolation), the IPC transport is a per-user Unix socket (not a TCP port), and there
+is an explicit `path_safety` module with a containment check. The single biggest strength
+is the disciplined no-shell subprocess layer. The single biggest risk is
+**untrusted-workspace code execution via toolchain resolution**
+(`toolchain_paths.dart:79`): a malicious repo can ship a `native/dugite/bin/git`
+executable that clide will resolve and run. Secondary real issues: path-safety does not
+defend against symlink escape, and IPC command args are largely unvalidated/un-bounded.
+Supply-chain hygiene is mostly good but `licenses.yaml` has drifted from `pubspec.yaml`
+and native binaries are committed without SHA pinning.
+
+### Strengths
+
+- **No-shell subprocess execution.** `GitClient._run` (`client.dart:210`),
+  `PqlClient._run` (`client.dart:165`), and the PTY layer all pass `List<String>` args
+  directly. Classic command injection is structurally prevented.
+- **Toolchain uses resolved absolute paths** — git/pql/tmux resolved once to absolute
+  paths and reused.
+- **Path containment check exists and is used.** `resolveUnderRoot`
+  (`path_safety.dart:21`) collapses `..`/`.` without touching the filesystem and enforces
+  a prefix check with a separator guard. `files.read`/`files.ls` both call it.
+- **IPC is a per-user Unix socket, not a network listener.** No `ServerSocket` over TCP
+  anywhere; the default runtime path is in-process, eliminating the socket attack
+  surface in the shipped app.
+- **PTY FFI memory discipline** — all native memory allocated before `forkpty()`, `errno`
+  captured before `free()`, freed on every path.
+- **`pubspec.lock` is committed**, deps use exact pins (no carets), `licenses.yaml`
+  exists with per-dep purpose/license.
+
+### Findings
+
+- **[Critical] Malicious workspace can plant a git binary that clide executes.**
+  `toolchain_paths.dart:79-84` builds `'$workspaceRoot/native/dugite/bin'` and runs
+  `_firstExisting(['$dugite/git'])`; if that file exists it becomes the git binary for
+  all `GitClient` calls, **before** falling back to PATH. An attacker commits an
+  executable at `native/dugite/bin/git`; clide runs it on the first `git.status` (which
+  fires automatically on workspace open). Arbitrary code execution from merely opening a
+  repo. The `native/dugite` convention should resolve relative to the *clide install
+  dir*, never the workspace root.
+- **[Major] Path-safety does not defend against symlink escape.** `path_safety.dart:
+  35-51` explicitly does not resolve symlinks, and the filesystem layer
+  (`files_commands.dart:81-85`) never does either. A repo symlink `config -> /etc/shadow`
+  passes the containment check (the *link path* is under root) and clide reads the
+  target. Fix: after `resolveUnderRoot`, `resolveSymbolicLinksSync()` and re-verify
+  containment.
+- **[Major] IPC command arguments are unvalidated and unbounded.**
+  `DaemonDispatcher.dispatch` (`dispatcher.dart:26`) and `IpcRequest.fromJson`
+  (`envelope.dart:49`) do no schema validation. No size limit on `files.read`, no count
+  cap on `git.log`, no check that `git.checkout`'s `branch` (`git_commands.dart:240`)
+  isn't a `-`-prefixed flag. `git diff`/`stage` use `--` separators (good), but
+  `checkout(branch)` and `push(remote, branch)` do not — argument injection
+  (`git checkout --upload-pack=...`) is possible.
+- **[Minor] macOS entitlements disable library validation.**
+  `macos/Runner/Release.entitlements` sets `disable-library-validation` = true with no
+  App Sandbox entitlement. Arguably needed for the `dlopen` of `libtree-sitter.so`, but
+  combined with no sandbox a compromised process has full user-level filesystem access.
+- **[Minor] `licenses.yaml` has drifted from `pubspec.yaml`.** Lists dev-dep `test` at
+  `1.25.8` but `pubspec.yaml:60` pins `1.30.0`; lists a `lints 5.0.0` not in
+  `pubspec.yaml` at all. The two-step-commit guardrail is being violated.
+- **[Minor] Native binaries committed without SHA pinning.** `native/linux-x64/` has
+  `libtree-sitter.so` (24 MB) and `ptyc` (22 KB) committed with no `SHA256SUMS` manifest.
+  CLAUDE.md says native deps are "pinned by SHA"; that pinning is not evidenced.
+- **[Informational] No secrets service** — clide stores no tokens; git auth is delegated
+  to the system credential helper. The right call; noted so the absence reads as
+  deliberate.
+- **[Informational] Lua runtime is a stub** — `lib/lua/src/host.dart` is Tier-0. Design
+  intent (strip `io`/`os.execute`/`package.loadlib`/`debug`) is sound; re-assess at Tier
+  6 — sandbox-escape via FFI re-entry will be the concern.
+
+### Recommendations
+
+**Quick wins:** fix toolchain resolution to resolve `native/dugite` against
+`Platform.resolvedExecutable`'s directory, never `workspaceRoot` (closes the Critical);
+add symlink re-check in `files.read`/`files.ls`; reconcile `licenses.yaml` with
+`pubspec.yaml`; reject `-`-prefixed values for `branch`/`remote`/`path` args (or use
+`--` everywhere, including `checkout`).
+
+**Larger efforts:** schema-validate the IPC surface with typed arg schemas + size/count
+bounds; add a committed `native/SHA256SUMS` verified by `make` and CI; revisit macOS
+sandboxing (App Sandbox with explicit exceptions); security-review the Lua FFI boundary
+and capability table before Tier 6 ships.
+
+### Scorecard
+
+| Area | Rating | Justification |
+|---|---|---|
+| Subprocess safety | 2/5 | No-shell arg lists are excellent, but the workspace-relative dugite path is a real RCE; argument-injection on `checkout`/`push` unmitigated. |
+| IPC input validation | 3/5 | Per-user Unix socket + in-process default sharply limits exposure, but zero arg-schema validation and no size/count bounds. |
+| Path/filesystem safety | 3/5 | Real containment check that's actually wired in, undermined by the unhandled symlink-escape gap. |
+| Dependency/supply-chain hygiene | 3/5 | Exact pins, committed lockfile, documented deps — but `licenses.yaml` drift and missing SHA manifest for committed native binaries. |
+| Secrets & sandboxing | 3/5 | Correctly delegates secrets; Lua sandbox is only a stub; macOS runs with library validation off and no App Sandbox. |

+
+## 6. Docs, governance & DX — TPM / Developer-Experience Consultant
+
+### Executive summary
+
+clide runs an unusually disciplined governance system for a solo-dev pre-v2.0 project:
+67 decision records across six domains, with a parser-validated DQR structure, anchored
+cross-references, and a `make decisions-validate` gate wired into pre-push. The biggest
+strength is that the DQR system is genuinely *alive* — questions get resolved with dated
+amendments, superseded decisions are marked, and decisions cite the commits that
+implement them. The biggest risk is **documentation drift in the narrative docs**:
+`README.md` and `docs/initial-plan.md` describe an architecture (Go sidecar, `ptyc/` C
+helper, `app/` subdirectory, separate daemon) that three major decisions (D-5, D-56, the
+FFI pivot) have since dissolved. A new contributor reading the README first would build
+a wrong mental model.
+
+### Strengths
+
+- **DQR system is maintained, not ornamental.** Resolved questions carry dated
+  resolution lines pointing to the deciding D-record (`questions/architecture.md:39`
+  Q-6→D-57). D-40 carries a `[SUPERSEDED]` tag and an amendment line.
+- **Decisions are linked to code and commits.** D-67 (`decisions/process.md:61`) cites
+  implementing commits `01a99ed`, `d162ba2`. D-66 references `ci/test.sh` by path.
+- **Governance migration was done cleanly** — the `decisions/` → `governance/`
+  restructure updated cross-references and the auto-generated index.
+- **Commit discipline is real.** `git log` shows imperative subjects, no Conventional
+  Commits prefixes, ticket refs, logical scoping — exactly what `git-commit/SKILL.md`
+  prescribes.
+- **`licenses.yaml` is thorough** — all six runtime Dart deps present, plus fonts/native
+  libs, with purpose justifications. *(Note: the Security reviewer found version drift
+  in this file — see Finding above; the two reviewers examined different rows.)*
+- **Makefile is self-documenting** (`##` help annotations) and matches `CLAUDE.md`.
+
+### Findings
+
+- **[Critical] `docs/initial-plan.md` is badly stale.** The "north-star" doc (linked
+  from `CLAUDE.md:14` and `README.md:44`) still describes a Go sidecar
+  (`initial-plan.md:4,55,189`), `clide --daemon` long-running process (`:162-164`),
+  `app/` subdirectory layout (`:184-204`), and `project.yaml` (`:172`) — all contradicted
+  by D-5, D-56, and the single-package-at-root reality. Nothing flags it as historical.
+- **[Critical] `README.md` describes a dissolved architecture.** `README.md:10`
+  documents `ptyc/` as a live component; `README.md:36` lists `make ptyc-build`. The
+  `ptyc/` directory does not exist, the Makefile has no such target, and the CHANGELOG's
+  own Unreleased section records ptyc's removal.
+- **[Major] `README.md:44` links to `decisions/`** — a directory that no longer exists
+  (migrated to `governance/`). Dead link in the primary onboarding doc.
+- **[Major] CHANGELOG has duplicate subsection headings in `[Unreleased]`.** Three
+  `### Changed` blocks (`CHANGELOG.md:100, 114, 168`), two `### Fixed`, two `### Removed`
+  in the 2.0.0 section. Keep a Changelog 1.1.0 expects one of each per release.
+- **[Major] No `CONTRIBUTING.md` or onboarding doc.** For a project "intended to ship
+  publicly to other developers," there is no contributor guide; the build/test story is
+  scattered across `CLAUDE.md` (Claude-oriented), `README.md` (partly wrong), and
+  Makefile help.
+- **[Major] Coverage-floor governance contradicts itself.** D-66 (`testing.md:65`) says
+  the floor lives at `coverage/floor.txt` starting "≈35%"; `CHANGELOG.md:44-46` says it's
+  in `pubspec.yaml` `coverage_floor:` starting at 34%; the latest commit is `9030e56
+  hold coverage_floor fixed at 90`. Three sources, three mechanisms/values. D-66 was
+  never amended.
+- **[Minor] `ci/release.sh` is a stub that still references goreleaser/sidecar** — Go
+  tooling for a project with no Go.
+- **[Minor] CHANGELOG `[2.0.0] — 2026-05-03` dating** — the v2.0.0 tag is dated
+  2026-05-03 but the enormous Unreleased section represents ~80 commits of post-tag work
+  with no interim version.
+- **[Minor] Stale-ish open questions** — Q-25 (body text face) is de facto resolved by
+  D-43/D-44 and the shipped impl; Q-1/Q-2/Q-3 ("defer until Tier 1 is in real use") are
+  due for triage now that Tier 1 has shipped.
+- **[Minor] Skills system is coherent but undocumented as a set** — eight skills under
+  `.claude/skills/`, no index.
+
+### Recommendations
+
+**Quick wins:** rewrite `README.md`'s `ptyc/` sections and fix the `decisions/` link;
+banner `docs/initial-plan.md` as historical (or split out a current
+`docs/architecture.md`); merge the duplicate changelog subsection headings; amend D-66 to
+reflect the floor's actual location/mechanism/value with a dated amendment line; triage
+Q-1/2/3/25.
+
+**Larger efforts:** write a human-facing `CONTRIBUTING.md` (clone →
+`make hooks && flutter pub get` → `make test` → DQR workflow → commit conventions); cut
+an interim release to drain the ~80-commit Unreleased backlog; add a
+`.claude/skills/README.md` inventory; establish a periodic governance sweep (the repo
+even has a `clean-house` skill for exactly this).
+
+### Scorecard
+
+| Area | Score | Justification |
+|---|---|---|
+| Governance discipline | 4/5 | DQR system genuinely maintained — but D-66 drift and untriaged Tier-1-era questions show the sweep cadence lags the code. |
+| Documentation accuracy | 2/5 | Both primary onboarding docs describe a dissolved Go-sidecar/ptyc/daemon architecture; `CLAUDE.md` is accurate by contrast. |
+| Changelog hygiene | 3/5 | Per-commit discipline is followed, but duplicate subsection headings violate the standard and an 80-commit Unreleased backlog undermines the format. |
+| Contributor onboarding | 2/5 | No `CONTRIBUTING.md`; build story split across three docs, one wrong; `CLAUDE.md` is Claude-addressed, not human-addressed. |
+| Convention adherence | 4/5 | Commit style, DQR claiming, `licenses.yaml` two-step rule demonstrably followed; docked for the changelog defects and the README gap. |

+its finishing is incomplete.** The extension contract, test helpers, FFI discipline,
+governance system, and token system are all things most projects never get right. The
+gaps — IPC not wired, keyboard not operable, docs describing a dead architecture, a

+solo project's implementation outruns its connective tissue. They are concentrated, not
+diffuse, and the quick-win column above would close most of the critical ones in a few

+
+## Shape
+
+clide is a **single Flutter package at the repo root**. There is no
+sidecar process, no separate daemon, no Go binary. One `flutter run`
+boots the whole IDE.
+
+```
+flutter desktop app  (lib/main.dart)
+  ├── kernel services (lib/kernel/)        — theme, i18n, settings, panels,
+  │                                          commands, focus, scheduler, …
+  ├── core subsystems (lib/src/)           — ipc, daemon dispatch, panes,
+  │   │                                      pty, editor, files, git, pql

+  ├── built-in extensions (lib/builtin/)   — claude, editor, files, git, terminal,
+  │                                          welcome, … each a ClideExtension
+  └── extension framework (lib/extension/) — contract + dependency-gated activation
+```
+
+### Process model
+
+One OS process. The Flutter app hosts:
+
+- the IPC dispatcher (`DaemonDispatcher` in `lib/src/daemon/`),
+- every subsystem handler (pane/files/editor/git/pql),
+- the extension manager and all built-in extensions.
+
+`tmux` is the only external long-lived process — it owns Claude
+session persistence so panes survive app restarts (D-41). The app
+re-attaches via `tmux new-session -A` on boot.
+
+PTYs are spawned natively from Dart. `lib/src/pty/native_pty.dart`
+calls `posix_openpt()` + `posix_spawn()` via FFI; the child inherits
+the slave PTY as stdin/stdout/stderr. No C helper binary.
+
+### Native dependencies
+
+Vendored under [`native/`](../native/) with per-platform subdirectories
+(`linux-x64/` today). Currently:
+
+- `libtree-sitter.so` — wasmtime-embedded tree-sitter for syntax
+  highlighting. Loaded via `dart:ffi`. See
+  `lib/kernel/src/syntax/tree_sitter_ffi.dart`.
+
+Each entry is listed in [`assets/licenses.yaml`](../assets/licenses.yaml)
+with version + SHA expectation (D-42).
+
+### External tools
+
+clide shells out to two binaries at runtime:
+
+- **`git`** — vendored as `dugite-native` if present at the install
+  directory; otherwise `PATH` `git`. Resolution happens at
+  `lib/kernel/src/toolchain_paths.dart`. **Never resolves against the
+  open workspace** (T-98).
+- **`pql`** — the [pql](https://github.com/postmeridiem/pql) project
+  query language; supporter tool, wrapped in `lib/src/pql/`. Clide
+  never re-implements pql features (D-3).
+
+## Surfaces
+
+### Claude-facing — `clide` CLI
+
+Per D-1 and D-6, Claude talks to clide exclusively via Bash. Every
+state-changing command emits one or more events on a long-lived
+event stream; every UI affordance has a matching CLI verb. See D-6
+for the subsystem/verb/event contract.
+
+> **Caveat (2026-05):** the Unix-socket server that exposes the
+> dispatcher to a thin `clide` C client is currently unimplemented.
+> Today's working path is in-process direct dispatch. See **T-99**
+> (IPC server implementation) and **D-68** (dual integration surface
+> — Bash CLI primary, MCP secondary).
+
+### User-facing — Flutter desktop
+
+Three-column layout (sidebar / workspace / context) with collapsible
+panels, a custom title bar, and per-panel "hats" for branding +
+window controls. The interaction model is documented in D-47 and
+neighboring decisions.
+
+## Subsystems at a glance
+
+| Subsystem | Location | Owns |
+|---|---|---|
+| IPC envelope + dispatcher | `lib/src/ipc/`, `lib/src/daemon/` | request/response framing, command registration, broadcast events |
+| Pane registry | `lib/src/panes/` | spawn/list/write/resize/close, event emission |
+| PTY | `lib/src/pty/` | `posix_openpt` + `posix_spawn`, reader isolate, signal forwarding |
+| Editor | `lib/src/editor/` | buffer registry, open/save/setContent |
+| Files | `lib/src/files/` | ls / read / watch, path-safety containment check |
+| Git | `lib/src/git/` | client (no shell), status/diff/operations parsing |
+| Pql wrapper | `lib/src/pql/` | shell-out only; never re-implements pql |
+| Kernel services | `lib/kernel/src/` | theme, i18n, settings, panels, commands, focus, syntax |
+| Extensions | `lib/extension/`, `lib/builtin/` | dependency-gated activation, contribution points |
+
+## Build + test
+
+```
+make hooks && flutter pub get   # one-time setup
+make run                        # launch app
+make test                       # analyze + format + unit + widget + golden

+make test-integration           # real-app boot tests
+make push-check                 # the full pre-push gate
+```
+
+The pre-push gate enforces a 95% line-coverage floor (D-66), a
+40-word soft / 60-word hard CHANGELOG bullet cap, all unit/widget
+tests, and the a11y contract.

 ## Status: Root cause found

 The PTY master fd is valid (`isatty=1`), SCM_RIGHTS transfer is correct, all struct layouts are correct. The problem is **timing**: the reader isolate starts too late and the shell has already exited by the time `read()` is called on the master fd. macOS returns EOF (n=0) immediately when the slave side is closed — unlike Linux which buffers data.

 ## 1. Executive Summary

 Previous attempts to fix the PTY functionality on macOS have failed, even after correcting a deadlock in the Dart code. The core of the problem appears to be a fundamental mismatch in how the C helper (`ptyc`) constructs a control message and how the Dart FFI layer is trying to parse it.

+### D-69: published themes are user contracts; ship -hc variants for a11y
+- **Date:** 2026-05-17
+- **Decision:** The four bundled themes that ship under a recognisable name — `clide`, `midnight`, `paper`, `terminal` — are user contracts. Their palette colours (including syntax tokens, status colours, and borderHi) MUST NOT be retuned to satisfy contrast gates. When a stricter contrast check would fail one of them, the fix is one of: (a) ship a sibling theme with `-hc` (high-contrast) or `-cb` (colour-blind) in the name and enforce the strict pair set only there, or (b) split `canonicalPairs` into a *baseline* set every theme must pass and an *extended* set that only the `-hc`/`-cb` variants must pass.
+- **Rationale:** Users pick `midnight` because it looks like VS Code, `paper` because it reads as a drafting sheet, `terminal` because of the amber-on-near-black tmux feel. Quietly darkening `paper`'s success/warning/info or boosting `midnight`'s `borderHi` to pass a WCAG-AA check changes what they got and what they signed up for. A11y is a Tier-0 contract ([D-20](#d-20-a11y-is-a-tier-0-contract)), but it's served by *offering* an accessible variant, not by overwriting the aesthetic ones. VS Code itself ships `Default Dark+` and a separate `Default High Contrast` for exactly this reason.
+- **Cost:** Two extra theme files per "named" theme when we add a11y variants. The bundled-theme contrast gate ([D-22](#d-22-wcag-aa-contrast-gate-on-bundled-themes)) needs a baseline/extended split so the named themes don't fail the strict pairs.

 ### D-1: CLI-first, not MCP
 - **Date:** 2026-04-20 (was ADR 0001; ported from the claudian lineage)
+- **Amendment (2026-05-15):** D-1's intent — the CLI is the *primary* agent-facing surface, with the same contract as pql — stands. An additional `/ide`-compatible MCP surface is added per [D-68](#d-68-dual-integration-surface-bash-cli-primary-mcp-secondary); both wrap the same in-process dispatcher. The escape-hatch line in this record's Cost ("nothing here precludes adding [MCP] later that shells out to the same CLI") is realised — the MCP server does not bypass the CLI's surface, it offers a second transport to it.
 - **Decision:** Claude talks to clide exclusively via Bash (`clide …`). No MCP server. No protocol layer in Claude's face. The CLI uses the same exit-code + stderr-JSON contract as pql.
 - **Context:** The two mainstream options for the agent-facing surface were an MCP server or a plain Bash CLI matching pql's contract.
 - **Rationale:** Same mental model as pql for the agent — one tool-use pattern covers both. No MCP runtime to host, authenticate, or keep in sync with client versions. User/Claude parity is easier to enforce: every CLI subcommand must have a UI affordance in the Flutter app and vice versa ([D-6](#d-6-cli-and-event-surface-contract)). Claude Code's `Bash(clide *)` allow rule is the only configuration clide needs on the agent side.

 - **Amendment (2026-04-23):** The separate daemon process and two-package layout are dissolved per [D-56](#d-56-dissolve-daemon-process-flutter-app-hosts-ipc-server). Dart-core principle survives; the daemon binary does not.
 - **Amendment (2026-05-07):** `ptyc` retired. PTY spawning moved to Dart FFI `forkpty()` (`lib/src/pty/native_pty.dart`). The `ptyc/` source tree, `PtySession`, and `scm_rights.dart` are removed. `pql` remains the sole external supporter tool.
+- **Amendment (2026-05-17):** `forkpty()` replaced with `posix_openpt()` + `posix_spawn()` (T-96). `forkpty` calls `fork()` underneath, which is unsafe in the multithreaded Dart VM: ~5% of spawns deadlocked in the child before `execve` due to libc locks held by ghost-threads at fork time. `posix_spawn` uses `vfork` under glibc/musl/macOS, keeping the parent suspended until `execve` completes — no Dart code runs in the child. Side benefit: dropped the `libutil.so.1` dynamic dependency; PTY now resolves entirely against libc via `DynamicLibrary.process()`.
 - **Decision:** Three moves. **(1) Dart is the core language.** Everything that used to live under `sidecar/` — IPC server, CLI dispatch, process management, file watching, git shell-outs, pql wrapper — is written in Dart. Two execution modes of one Dart AOT binary: `clide <subcommand>` (one-shot, pql-style) and `clide --daemon` (long-running, owns PTYs and subprocesses, survives app restarts). The Flutter app imports the Dart core as a library *and* connects to the daemon over IPC. **(2) The sidecar directory dissolves.** Layout is `app/` (Flutter UI), `lib/` (Dart core), `bin/clide.dart` (AOT entry), `ptyc/` (C helper), no `sidecar/`, no Go module. **(3) `ptyc` is a pql-peer supporter tool.** Small C binary that does `posix_openpt` + `fork` + `exec` + fd-passing via `SCM_RIGHTS`; clide wraps it the same way it wraps pql. Shells out for every PTY (terminal pane, tmux session, Claude, LSP server, debug adapter — one code path). Consumers other than clide can use `ptyc` standalone.
 - **Context:** [R-2](rejected.md#r-2-go-sidecar) picked Go for the sidecar/CLI on two premises: (a) the heavy work belongs in a language separate from the UI layer, and (b) pql is Go so the muscle memory transfers. On reassessment, both premises broke: the "heavy work" is I/O-bound glue that `dart:io` covers cleanly — the real choice was **separate process vs shared language**, and separate-process is what matters. PTY is the one place Dart is genuinely weak (multi-threaded VM can't safely `fork()`), and once you accept a small native helper, *nothing else* needs to be in the same language.
 - **Rationale:** One toolchain for the IDE proper (Flutter + Dart). C toolchain needed only to build `ptyc` — tiny, rarely-changing. Session persistence stays because PTY master fds live in the Dart daemon process, not the app. `ptyc` naming: **p** for *project* (parallel to pql's *project query language*), **ptyc** reads as both "PTY + child" (domain vocabulary) and "PTY + C" (implementation language). Usable from Dart, Python, Go, shell — anywhere a subprocess can be spawned and a fd received.

+### D-68: Dual integration surface — Bash CLI primary, MCP secondary
+- **Date:** 2026-05-15
+- **Decision:** clide exposes two integration surfaces over the same in-process `DaemonDispatcher`. **(1) Bash CLI over Unix socket — primary.** Per [D-1](#d-1-cli-first-not-mcp) and [D-56](#d-56-dissolve-daemon-process-flutter-app-hosts-ipc-server), a thin C client (`clide …`) connects to a per-user Unix socket served in-process by the Flutter app, exchanges JSON-lines, and exits. This is the surface Claude-Code-in-a-pane uses; it is also the surface for human shell use, scripts, and external editor integrations. Full action surface — `pane.*`, `files.*`, `editor.*`, `git.*`, `pql.*`, …. **(2) `/ide`-compatible MCP server — secondary.** clide additionally serves an MCP endpoint compatible with Claude Code's `/ide` integration (the same protocol VS Code and JetBrains plugins serve). Minimum tools: `mcp__ide__getDiagnostics`, `mcp__ide__executeCode`. Optional `mcp__clide__*` namespace exposing high-leverage clide tools is deferred to [Q-32](../questions/architecture.md#q-32-mcp-tool-surface-minimum-slash-ide-or-extended-clide-tools). Transport choice deferred to [Q-33](../questions/architecture.md#q-33-mcp-transport-sse-websocket-stdio-or-all). The MCP server wraps the *same* `DaemonDispatcher`; there is no second source of truth.
+- **Context:** [D-1](#d-1-cli-first-not-mcp) chose CLI-first over MCP-only because MCP alone doesn't cover the action surface clide needs — Claude Code's `/ide` MCP exposes only two narrow tools (`getDiagnostics`, `executeCode`), enough for Claude to read diagnostics and run Jupyter cells but not enough to *drive* an IDE. The CLI surface gives full reach. But for users who run Claude Code *outside* clide and connect via `/ide`, MCP is the only path Claude Code knows; not serving it means clide is invisible to that workflow. The two surfaces are complementary, not alternatives. Reinforced by the [2026-05-14 consultant review](../../consultants.md): the architect flagged the absent socket server as the most critical drift; user confirmed the socket server (D-56 path a) plus an MCP companion.
+- **Rationale:** Both surfaces wrap the same dispatcher, so neither becomes a second source of truth. CLI remains the contract user/Claude parity ([D-6](#d-6-cli-and-event-surface-contract)) is enforced against. MCP is added because the `/ide` ecosystem is real and growing — VS Code, JetBrains, Cursor, Windsurf all serve compatible MCP — and clide should be a peer there. The implementation cost is a protocol adapter + tool definitions, not duplicate business logic.
+- **Cost:** Two transports to maintain. Mitigated by both wrapping the same dispatcher: the MCP adapter is the only thing that has to track `/ide` protocol evolution. If `mcp__clide__*` tools are added (pending Q-32), surface bloat is the obvious risk — every CLI verb invites an MCP twin; resist by default, justify on user need.

 ### D-66: Line coverage gate at 95%, ratcheted from current
 - **Date:** 2026-05-06
+- **Amendment (2026-05-17):** Floor location consolidated — the committed floor lives at `coverage_floor:` in `pubspec.yaml` (single source of truth); `coverage/floor.txt` is no longer used. The 95% target was reached on 2026-05-17; floor is **95** as of that date (T-91 closed). A pre-push **CHANGELOG concision gate** (`ci/changelog_gate.sh`) runs alongside the coverage gate; both live under `make push-check`. A separate `make push-check-full` adds `test-integration` + `smoke-bundle` for pre-release checks (T-103).
 - **Decision:** The pre-push gate runs `flutter test --coverage --exclude-tags forkpty`, parses `coverage/lcov.info`, and hard-fails if total line coverage drops below a committed floor at `coverage/floor.txt`. The floor starts at the actual current coverage (≈35%, dragged down by `lib/src/terminal/`'s 0.4%) and only ever ratchets up. The end target is 95%; getting there is tracked as a campaign of deliberate floor bumps under one epic ticket. **No carve-outs** — code under `lib/` is owned regardless of file-header attribution, including the terminal emulator port. Branch coverage is not gated (Dart's lcov output models it weakly). Lint suppressions to dodge the gate are never acceptable.
 - **Rationale:** A flat 95% threshold today blocks every push; an informational coverage report rots into noise. The committed-floor ratchet makes "don't make it worse" the durable rule and turns the journey to 95% into explicit, reviewed bumps rather than a single overnight cliff. Excluding `forkpty`-tagged tests matches `ci/test.sh` (forkpty + flutter test runner are incompatible — see `test/pty/session_test.dart`).
 - **Cost:** Pre-push wall time grows by `flutter test --coverage` (currently ≈11 s on this tree). Acceptable within D-29's < 90 s budget; reassess if it slips. Floor bumps require an explicit edit to `coverage/floor.txt` in the same commit that adds tests — so contributors can't silently raise it.

+- **Status:** Open
+- **Question:** [D-68](../decisions/architecture.md#d-68-dual-integration-surface-bash-cli-primary-mcp-secondary) commits clide to an `/ide`-compatible MCP server. The minimum surface is the two tools Claude Code's `/ide` integration currently expects: `mcp__ide__getDiagnostics` (lint/diagnostics for a file) and `mcp__ide__executeCode` (run code in a Jupyter kernel). Do we stop there, or also expose a `mcp__clide__*` namespace with higher-leverage tools (`open_file`, `goto_symbol`, `pql_query`, `pane_spawn`, `git_status`, …) so MCP clients other than Claude Code (Cursor, Windsurf, VS Code Copilot) can drive clide as a real backend?
+- **Context:** The minimum surface keeps clide a good citizen in the `/ide` ecosystem and avoids duplicating the CLI in MCP form. The extended surface would let non-Claude-Code MCP clients integrate richly, but invites surface bloat (every CLI verb tempted to gain an MCP twin) and a maintenance second front. Note that for *Claude-Code-in-a-clide-pane*, the CLI surface already covers this — extended MCP tools serve external MCP clients only.

+### Q-33: MCP transport — SSE, WebSocket, stdio, or all?
+- **Status:** Open
+- **Question:** Claude Code's `/ide` integration connects via SSE-IDE or WS-IDE (URL passed at startup). MCP also supports stdio for process-spawn clients. Which transport(s) should clide's MCP server expose — SSE only (the most common `/ide` server pattern), SSE + WS (broader compatibility), or all three including stdio?
+- **Context:** Transport choice affects discovery and lifecycle. SSE/WS need a port and a published URL, which collides with the `XDG_RUNTIME_DIR` Unix-socket model used for the CLI; we'd likely publish the URL alongside the socket path (env var or `XDG_RUNTIME_DIR` discovery file). stdio is process-per-client and works for clients that prefer process-spawn over network. Decision interacts with [Q-32](#q-32-mcp-tool-surface-minimum-slash-ide-or-extended-clide-tools) — if the surface stays at the `/ide` minimum, SSE alone is sufficient.
