harden PTY test timeouts (5s -> 20s)

The real-shell PTY tests gave a child + reader-isolate only 5s to
deliver first output; under transient scheduling latency that was
occasionally exceeded, flaking the pre-push gate (retry:2 usually but
not always absorbed it). A working PTY echoes in well under a second,
so 20s is pure headroom — a genuinely dead PTY still fails, just later.
Verified 5/5 clean runs after the bump.

Every `make` build/run/test target regenerates `lib/src/build_info.g.dart` (gitignored) and rewrites `assets/licenses.yaml` `self.version:` from it — so the Flutter app sees the current version everywhere without manual sync.

+**Architectural commitments (read these first):**
+- D-70 — socket path is `$XDG_RUNTIME_DIR/clide/<sha256(workspace-root)[:16]>.sock` on Linux, `$HOME/Library/Caches/clide/<sha256(workspace-root)[:16]>.sock` on macOS. No env override. Workspace root = git toplevel.
+- D-71 — socket file is `0600`, parent dir is `0700`. No token auth at this layer.
+- D-72 — multi-connection accept loop, serial dispatch on the main isolate. Per-handler isolate offload as needed; not the IPC layer''s concern.
+
+**Acceptance:**
+1. lib/src/ipc/server.dart exists; binds an AF_UNIX socket at the D-70 path; creates the parent dir with the D-71 perms.
+2. App boot starts the server; app shutdown closes the socket file cleanly and removes it.
+3. `socat - UNIX-CONNECT:$SOCK <<< ''{"command":"git.status"}''` returns a JSON-line response. Tests use a synthetic socket fixture (tempdir + XDG_RUNTIME_DIR override at the env level).
+4. Multi-connection accept loop — concurrent socat invocations interleave at the I/O level but serialise through DaemonDispatcher (per D-72) without failing each other.
+5. Stale socket on boot (left over from a crashed clide) is detected and unlinked before binding — same `live-daemon probe` pattern already used elsewhere in the codebase.
+6. No client yet — that lands in T-126.

+---
+Design resolved 2026-05-20 (see D-74). Co-registration model, NOT a central map:
+
+- The argv parser (lib/src/cli/argv_to_request.dart) only knows syntactic shape (identifier/flag charset, -- terminator); it has NO per-command argument knowledge. So this is build-fresh, not a lift — each handler currently hand-reads its own keys.
+- Extend the DaemonDispatcher registration API to carry an optional typed schema per command. The dispatcher accumulates a cmd->schema registry as commands register (built-in register*Commands modules supply theirs; extension CommandContributions carry their own — central static map rejected because it cannot see extension-contributed commands, D-46).
+- DaemonDispatcher.dispatch validates req.args against schema[cmd] BEFORE invoking the handler (hook at dispatcher.dart line 39, the `return h(req)` call). Violation -> userError (sysexit 64). Commands with no schema dispatch unvalidated (opt-in per command) until migrated.
+- Constraint vocabulary is hand-rolled (prefer-zero-deps): per-arg required/optional, kind, charset/regex, numeric range. Collapses the _ResizeArgs-style hand-lifts (panel_commands.dart, T-119) into schema.
+- KEEP existing T-104 checks as defense-in-depth: validateGitRef (lib/src/git/operations.dart:46) and the count/path caps (lib/src/daemon/git_commands.dart:18,23). The git client is callable directly from the Flutter UI, not only via the dispatcher — do not remove them.
+- OUT OF SCOPE: MCP tools/list generation from the registry — deferred to the T-130 track.
+
+Acceptance:
+1. Dispatcher validates req.args against a registered per-command schema before the handler runs; violations return userError.
+2. At least the security-relevant commands (git ref/remote/path args, panel.resize) carry schemas; argv-injection + caps still enforced (no regression vs T-104).
+3. validateGitRef + git caps retained as defense-in-depth.
+4. No third-party validation dep; no lint suppressions.
+5. Tests cover: schema accept/reject per constraint kind, dispatcher-level rejection, and that an unschema-d command still dispatches.

Adding a tap-driven assertion hung the 10-minute Flutter test timeout consistently (find.byTooltip, find.bySemanticsLabel, and find.byKey + tap variants all reproduced).
+
+Hypothesis: ClideTooltip wraps the toggle in a MouseRegion whose onEnter awaits Future.delayed(showDelay). Some path during tap simulation (or surrounding pump scheduling) keeps that timer pending, and the test runner waits the full 10-minute idle timeout before declaring it stuck.
+
+Next steps:
+- Reproduce in isolation against a stripped-down harness pumping just the _StickyToggle widget.
+- Determine whether the hang is the MouseRegion timer or another future (e.g., the welcome-tab activation, toolchain check).
+- Either fix the underlying cause or use fakeAsync.run() to drain the timers explicitly.
+
+Until then, ProjectManager unit tests in test/kernel/src/project_test.dart cover the sticky-startup logic (14 cases including round-trip, no-op, idempotent flip, ambiguity, and openStickyOrNothing).', 'T-115 follow-up: tap-driven widget test for sticky-startup toggle.
+
+Adding a tap-driven (or even render-only) test that pumps WelcomeView with a non-empty recents list hangs the Flutter test runner until timeout.
+
+Investigation 2026-05-22 (narrowed the cause):
+- The hang is SYNCHRONOUS: `flutter test --timeout 45s` never fires; only an external `timeout` kills it. So the Dart isolate event loop is blocked, not awaiting.
+- Reduced to a minimal repro: pumping two NESTED ClideTappable widgets under the shared test harness (test/helpers/widget_harness.dart) hangs. A SINGLE ClideTappable (as in _ActionRow) renders fine — that is why all existing WelcomeView tests pass (empty recents = no nested tappable). The recents path nests one: _RecentRow is a ClideTappable whose subtree contains _StickyToggle (a Semantics-wrapped ClideTappable).
+- The shared harness uses `Overlay(canSizeOverlay: true)` over a zero-size `MediaQuery`, which triggers an intrinsic-sizing pass. Strongly suspect the nested ClideTappable (Focus + MouseRegion + GestureDetector + DecoratedBox stack) diverges under intrinsic dimension computation.
+- Workarounds that did NOT help: setting tester.view.physicalSize; wrapping in SizedBox; wrapping in Center+SizedBox; a custom bounded MediaQuery harness (that custom harness hung even on a single tappable — likely its own confound, do not reuse it).
+- The prior ClideTooltip/MouseRegion-timer hypothesis is WRONG: the recents widgets pass no tooltip to ClideTappable, so no ClideTooltip is built, and _StickyToggle uses Semantics(tooltip:) (metadata only, no widget/timer).
+
+Next steps:
+- Decide whether this is a real ClideTappable bug (nested tappables would also hang the live app welcome screen with recents) or strictly a canSizeOverlay-intrinsic-sizing test artifact. Check the running app: open welcome with >=1 recent project and confirm it does NOT hang. If the app is fine, the fix is harness-side (give WelcomeView tight constraints so no intrinsic pass), and the shared harness or a welcome-specific harness needs adjusting. If the app DOES hang, ClideTappable has a real nested-layout bug — fix it (likely in lib/widgets/src/clide_tappable.dart intrinsic/layout handling) and this becomes higher priority.

The pre-T-137 terminal pane rendered each tab''s own PTY, so tabs were independent.
+
+Fix: bind each pane to a specific Claude session id.
+- claude CLI supports `--session-id <uuid>` (verified via --help). Spawn each pane''s claude with its own UUID; a transcript is named <session-id>.jsonl, so the pane''s transcript is <munged-cwd>/<uuid>.jsonl.
+- Reader targets that exact file via TranscriptReader''s `file:` param (added in T-139). Guard _tail against the file not existing yet (claude writes it shortly after spawn).
+- Each pane publishes/subscribes on a per-session MessageBus channel (conversation/<uuid>) so primary and secondary controllers don''t cross-talk.
+- UUID per pane, seeded by the tmux session name (the identity we already have): primary = deterministic from its stable session name (clide-claude-<slug>) so it RESUMES across restarts (D-41 continuity); secondary = random per spawn so each is a clean/fresh session (a deterministic secondary id would make starting a clean session impossible).
+
+Migration caveat: an existing tmux session created by the OLD code (no --session-id, claude picked its own id) won''t match the new deterministic id — it must be killed (claude.kill-all-sessions) once so the next spawn binds the controlled id.
+
+Open question to validate live: whether `claude --session-id <existing-uuid>` resumes vs. errors when re-spawned after the tmux session was killed (display works either way since the file is <uuid>.jsonl, but worth confirming claude starts).
+
+Acceptance: a secondary tab shows its OWN fresh conversation, independent of the primary; the primary keeps its conversation; both update live. Regression of T-137; relates to D-41.

+- Using the same registry to validate inbound IpcRequests at dispatch time (regex/charset constraints on branch/remote/path args).
+- Exposing the registry to the MCP server (T-130) so the `tools/list` payload is generated rather than hand-rolled.

+
+Adding a tap-driven (or even render-only) test that pumps WelcomeView with a non-empty recents list hangs the Flutter test runner until timeout.
+
+Investigation 2026-05-22 (narrowed the cause):
+- The hang is SYNCHRONOUS: `flutter test --timeout 45s` never fires; only an external `timeout` kills it. So the Dart isolate event loop is blocked, not awaiting.
+- Reduced to a minimal repro: pumping two NESTED ClideTappable widgets under the shared test harness (test/helpers/widget_harness.dart) hangs. A SINGLE ClideTappable (as in _ActionRow) renders fine — that is why all existing WelcomeView tests pass (empty recents = no nested tappable). The recents path nests one: _RecentRow is a ClideTappable whose subtree contains _StickyToggle (a Semantics-wrapped ClideTappable).
+- The shared harness uses `Overlay(canSizeOverlay: true)` over a zero-size `MediaQuery`, which triggers an intrinsic-sizing pass. Strongly suspect the nested ClideTappable (Focus + MouseRegion + GestureDetector + DecoratedBox stack) diverges under intrinsic dimension computation.
+- Workarounds that did NOT help: setting tester.view.physicalSize; wrapping in SizedBox; wrapping in Center+SizedBox; a custom bounded MediaQuery harness (that custom harness hung even on a single tappable — likely its own confound, do not reuse it).
+- The prior ClideTooltip/MouseRegion-timer hypothesis is WRONG: the recents widgets pass no tooltip to ClideTappable, so no ClideTooltip is built, and _StickyToggle uses Semantics(tooltip:) (metadata only, no widget/timer).
+
+Next steps:
+- Decide whether this is a real ClideTappable bug (nested tappables would also hang the live app welcome screen with recents) or strictly a canSizeOverlay-intrinsic-sizing test artifact. Check the running app: open welcome with >=1 recent project and confirm it does NOT hang. If the app is fine, the fix is harness-side (give WelcomeView tight constraints so no intrinsic pass), and the shared harness or a welcome-specific harness needs adjusting. If the app DOES hang, ClideTappable has a real nested-layout bug — fix it (likely in lib/widgets/src/clide_tappable.dart intrinsic/layout handling) and this becomes higher priority.
+- Once unblocked, this also unblocks lib/builtin/welcome/src/welcome_view.dart coverage (74 uncovered lines, the dominant lib/builtin/ gap toward the T-89 95% target).

+
+**Strategy — pure logic first, then UI:**
+
+1. **`core/buffer/`** (581 lines, biggest single chunk, all pure Dart) — line/segment/cell models, scrollback math, range queries. Unit tests exercise the data structure directly.
+2. **`core/escape/`** (473 lines, pure state machine) — feed ANSI/VT byte streams in, assert the resulting buffer/cursor state. Reusable corpus from xterm.js / xterm.dart upstream is fair game.
+3. **`core/input/`** (292 lines) — key + keytab tables; assert mapping from logical key to escape bytes per terminal mode.
+4. **`core/mouse/`** (51 lines) — encoder for SGR-1006 / X11 mouse protocols. Small, fast.
+5. **`utils/`** (251 lines) — circular buffer + helpers; trivial unit tests.
+6. **`(root)`** (`terminal.dart`, `terminal_view.dart`, 471 lines) — orchestration; some unit-testable, some needs widget tests.
+7. **`ui/`** (823 lines) — painters and render objects; widget + golden tests. Hardest, most pixel-sensitive.
+
+**Acceptance:**
+- `lib/src/terminal/` line coverage ≥ 95%.
+- All tests fast (<5 s for the area''s test files combined; no real PTY shell-out).
+- Helper fixtures live in `test/terminal/_helpers/` if they get reused across files.
+- Per D-66, no `// ignore:` directives or analysis_options excludes added to dodge coverage.
+- `coverage_floor:` in `pubspec.yaml` is bumped in lockstep — every commit that adds covering tests bumps the floor by the measured delta (rounded down to the integer below the new percentage).
+
+**Strategy on commit cadence:**
+Land tests in batches per sub-area (one commit per `core/buffer/`, `core/escape/`, etc.). Each batch:
+- Adds tests under `test/terminal/<sub-area>/`.
+- Re-measures coverage, bumps `coverage_floor:` to the new integer (or as high as the gate currently allows).
+- Documents in CHANGELOG under "Changed" (test-only changes can also fold into one CHANGELOG entry per area).

+**Out of scope:**
+- Refactoring `lib/src/terminal/` for testability — if a piece is genuinely untestable, surface it (don''t silence it). Code under `lib/` is owned regardless of upstream attribution; refactor to make it testable rather than carving it out.

+The dominant hole is `lib/src/terminal/` — the terminal emulator code. Header still credits xterm.dart upstream, but per CLAUDE.md ("Own the rendering stack") and the explicit guidance attached to this epic: in-tree code is owned, no carve-outs, same coverage bar.
+
+**End state:**
+- Total line coverage ≥ 95% (no per-area carve-outs).
+- Pre-push gate hard-fails on coverage drops via a committed floor (`coverage/floor.txt`); floor ratchets up only.
+- Per D-66 the gate lands at the *current* floor in the first child ticket; subsequent floor bumps come with the test-writing children.
+
+**Acceptance criteria for closing this epic:**
+1. `coverage/floor.txt` reads `95` (or higher).
+2. `flutter test --coverage --exclude-tags forkpty` produces ≥95% line coverage.
+3. The pre-push gate computes coverage and rejects pushes below the floor.
+4. No new `// ignore:` / `// ignore_for_file:` / analysis-options excludes were added to dodge the gate. Any suppression added during this campaign needs explicit approval and an inline reason at the suppression site.
+
+**Strategy / child shape:**
+The gate plumbing lands first so future test additions are visible as floor bumps. Then per-area sweeps — biggest holes first because they move the global number fastest, but each area is its own child ticket with its own scope.
+
+1. **Gate plumbing** (first child) — install the ratchet, lock in current floor, expose `make coverage-gate` and wire it into `make push-check`.
+2. **`lib/src/terminal/` sweep** (second child, by far the largest) — likely splits into sub-children once the area''s structure is mapped (parser, buffer, painter, gesture handling, mouse reporting, escape sequences, cell-grid measurement, etc.).
+3. **Per-area sweeps** — claim a child ticket when starting an area; close when the area hits 95%. Order by impact: terminal → widgets → pql → builtin → kernel → daemon → pty → git → ipc → files → extension → editor.
+4. **Final ratchet** — once total ≥ 95%, set floor to 95 and close the epic.
+
+**Out of scope:**
+- Branch coverage (lcov data is weak for branch on Dart; line coverage is the contract).
+- Integration / E2E coverage (only widget + unit feed lcov).
+- `lib/test_app.dart` exclusion: verify in the gate child whether Dart''s coverage tooling already excludes it; if not, decide explicitly rather than carve it out silently.

+
+Principle: Claude-centric first, CLI-first (D-6) a strong second. Accept isolated, version-pinned coupling to Claude Code internal contracts where it serves the Claude integration; preserve CLI/event surfaces where sensible.
+
+Acceptance: all child tickets done; D-record landed; Claude pane renders natively with working select+copy and no terminal; a tmux team surfaces as lead + auto-wrapping teammate tiles + meta sidebar; all fragile CC-internals parsing isolated and version-pinned.

+Refinement (2026-05-22, refinement-agent review):
+- Environment confirmed: tmux 3.6a; claude 2.1.148 (the version an-idea.md verified for tmux teammate spawning) -- PIN findings to 2.1.148. teammateMode absent from ~/.claude/settings.json (default auto) -> set teammateMode:tmux explicitly OR launch the lead inside tmux and rely on auto.
+- Check 3 ALREADY answered from a real ~/.claude/teams/*/config.json: {name,description,createdAt,leadAgentId,leadSessionId,members[]}; member = {agentId,name,agentType,model,joinedAt,tmuxPaneId (empty for lead, e.g. %154 for teammates),cwd,subscriptions,backendType:''tmux'',isActive,mode}. tmuxPaneId DOES populate -- spike just re-verifies on the pinned version.
+- Subagent path: <munged>/<session-uuid>/subagents/agent-<id>.jsonl (session UUID is a directory).
+- Check 5 (session-id) resolved by T-136: newest *.jsonl by mtime. Spike confirms only.
+- tmux -L clide socket may not exist unless the app is running; spike creates its own: tmux -L clide new-session -d -s teamhost ... claude.
+- Check 4 (paste): scope to @path file references (verifiable via send-keys headlessly). Clipboard-image needs an interactive display ($DISPLAY) -- note as interactive-only.
+- ACP directionality (an-idea.md s5) is OUT OF SCOPE: Zed-client concern; clide owns its GUI and does not use ACP.
+- Deliverable: findings note at docs/spikes/cc-team-internals-2.1.148.md (in-repo), feeding D-75 when authored (T-133). D-75 is claimed-but-unauthored (T-133''s job) -- the reference is forward-looking, not dangling.

 ### Added
 
+- tmux agent teams surface as native teammate tiles (T-139, T-140) —
+  when a Claude team is running, each teammate shows as a live
+  conversation tile beside the lead in a grid that wraps 1→2→3 columns,
+  with a resizable split. Identity and lifecycle come from the team
+  config; per-teammate content streams over the MessageBus.
+- Native composer in the Claude pane (T-138) — type below the
+  conversation and press Enter to send (Shift+Enter for a newline).
+  Submits via the tmux server (bracketed paste + Enter), so input
+  reaches Claude even when no tmux client is attached; multi-line goes
+  as one message.
+- File and image paste in the composer (T-138, T-142) — Ctrl/Cmd+V of a
+  copied file or clipboard image adds a removable chip (image thumbnail
+  or file icon) above the input; on send its `@path` is appended to the
+  message. Plain text pastes inline. Backed by a native `clide/clipboard`
+  channel (GTK + macOS).
+- Claude pane renders natively from the transcript (T-137, D-75) — the
+  conversation shows as native cards (user / assistant markdown /
+  thinking / tool-use / result) instead of a terminal, with text
+  selection + copy across cards. Claude still runs in tmux; the terminal
+  builtin stays for general use.
+- Multi-file editor tabs — the editor pane now shows one tab per open
+  buffer (filename + a dot when unsaved) via the shared tab strip;
+  opening a second file no longer replaces the first. Click a tab to
+  switch, × to close. Backed by the daemon's existing multi-buffer
+  model.
+- Typed IPC command-schema framework (T-119/T-120, D-74) — commands
+  register an argument schema beside their handler; the dispatcher
+  normalises argv into named args, coerces types, and validates
+  (charset, leading-dash, ranges, caps) before the handler runs.
+- `clide panel resize <slot>` CLI verb (T-119) — set an absolute size
+  with `--to` or nudge with `--by`; `editor` targets the split ratio.
+  Completes user/Claude parity (D-6) with T-111's keyboard resize.
+- Unix-domain IPC socket server in the Flutter app (T-99 / T-124).
+  Per-workspace path (D-70: `$XDG_RUNTIME_DIR/clide/<hash>.sock` on
+  Linux, `~/Library/Caches/clide/<hash>.sock` on macOS). 0600 socket
+  + 0700 parent (D-71). Multi-connection accept loop with serial
+  dispatch through `DaemonDispatcher` (D-72). Foundation for the C
+  `clide` client (T-126) and MCP (T-130). No client yet — testable
+  via `socat - UNIX-CONNECT:$SOCK`.
+- argv→IpcRequest translator (`lib/src/cli/argv_to_request.dart`) —
+  parses `clide SUBSYSTEM VERB [pos...] [--flag] [-- passthrough]` and
+  the umbrella commands (`status`, `tail`, `version`, `ping`) per D-6
+  into the wire envelope. Pure Dart; lets the C client (T-126) stay a
+  dumb pipe (T-99 / T-125).
+- `DaemonClient.reconnectAt(newPath)` — swap an active client onto a
+  different socket without restart (project switch in T-127).
+- Event streaming over the IPC socket (T-99 / T-129) — `clide tail
+  --events [--filter X]` opens a long-lived subscription, replays up
+  to 16 recent matching events per subsystem (D-6), and streams new
+  ones as JSON lines. C client loops on `data.streaming` ack. Slow /
+  broken subscribers drop themselves without blocking the bus.
+- MCP server over HTTP+SSE (T-99 / T-130, per D-68 / D-73). Localhost
+  HTTP listener advertises via `$HOME/.claude/ide/<pid>.lock` so
+  Claude Code's `/ide` discovers it. JSON-RPC 2.0 with the two
+  minimum `/ide` tools shipped as stubs
+  (`mcp__ide__getDiagnostics`, `mcp__ide__executeCode`); real
+  implementations follow.
+- C `clide` shell client at `native/clide-cli/clide.c`. Walks CWD up
+  to the git root, hashes to the per-workspace socket (D-70), ships
+  argv. `make clide-cli` builds it; on PATH, `clide status` works
+  from any clide-workspace directory once the app is up (T-99,
+  T-126).
+- Startup project picker — clide now opens to the welcome screen by
+  default instead of auto-opening the last project. A per-row
+  "always open this project on launch" checkbox in welcome's RECENT
+  list sets a sticky-startup flag; if exactly one project has it,
+  that one opens directly. Two or more, or none ⇒ picker (T-115).
+- CONTRIBUTING.md "Running clide from the shell" section — documents
+  the shell verbs, exit-code contract per D-68, and Claude Code
+  `/ide` MCP discovery via `~/.claude/ide/<pid>.lock` (T-131).
+
 ### Changed
 
+- The empty Claude pane now shows a native startup banner — clide logo,
+  session role, workspace, and tmux status — instead of a bare "Waiting
+  for Claude…" (T-149).
+- User and Claude turns in the conversation now render as distinct
+  accent-striped cards over a filled background — your prompts in the
+  theme focus colour, Claude's replies in Claude's brand orange
+  (T-143, T-144).
+- Claude conversation content now flows through the kernel MessageBus —
+  a reader tails the transcript and publishes items; the pane subscribes.
+  Decouples reading from rendering so the upcoming team panels can show
+  one lead plus a tile per teammate (T-137).
+- In-process IPC dispatch swapped for socket loopback (T-127). The
+  Flutter UI's `DaemonClient` now talks to its own `IpcServer` over
+  the same per-workspace Unix socket the C `clide` client uses — one
+  transport, one contract.
+- D-56 / D-68 amended with implementation notes — both decisions now
+  link out to T-99's eight slices (T-124–T-131) and the D-70/71/72/73
+  records they spawned (T-131).
+
 ### Deprecated
 
 ### Removed
 
+- `lib/kernel/src/ipc/in_process.dart` (`InProcessClient`) — replaced
+  by the socket-loopback `DaemonClient` (T-127).
+- `lib/kernel/src/backend.dart`, `lib/kernel/src/backend_entry.dart`,
+  `lib/kernel/src/ipc/isolate_client.dart` — the third unused IPC
+  path (a backend-isolate model that was never wired through). Only
+  the socket model survives now (T-128).
+
 ### Fixed
 
+- Claude secondary panes no longer flash a false "session exited" while
+  the session is alive (a transient tmux client exit is now verified
+  against the live session), and the tab and banner agree on the label
+  ("session N") (T-149).
+- Claude pane no longer gets stuck on "Waiting for Claude…" when its
+  session can't be bound (T-147) — e.g. a session left over from before
+  session-id binding, or a fresh machine. It now retires that stale
+  clide session and starts a clean one. Only clide's own `-L clide`
+  sessions are touched (never a terminal Claude, never transcript files).
+- Secondary Claude tabs showed the primary's conversation instead of
+  their own (T-146). Each pane now binds to its own session via
+  `claude --session-id`, so concurrent sessions in one workspace stop
+  colliding on the newest transcript — the primary keeps a stable id
+  (resumes), secondaries get a fresh one (clean session).
+- Claude pane no longer freezes the app on open — the transcript reader
+  caps its initial read to the recent tail, parses off the UI isolate,
+  and coalesces view notifications into one rebuild per burst (T-137).
+- Daemon-not-connected on startup — panels and the Claude pane raced
+  the socket loopback. Requests now wait briefly for an in-flight
+  connection, the server isn't restarted for the same workspace, and
+  the client connects once instead of twice.

+## The C `clide` shell client
+
+`clide` (the binary) is a ~250 LOC C program in
+[`native/clide-cli/clide.c`](native/clide-cli/clide.c) that talks to
+the running Flutter app's IPC socket so Claude (and you) can drive
+clide from any shell. It walks CWD up to the workspace's `.git`,
+computes the same FNV-1a 64-bit hash the Dart side uses (per D-70),
+opens the per-workspace socket, and sends argv across the wire under
+a sentinel `_argv` cmd. The argv parser lives in Dart
+([`lib/src/cli/argv_to_request.dart`](lib/src/cli/argv_to_request.dart)),
+so the C side stays a dumb pipe.
+
+Build it with `make clide-cli` — output lands at
+`native/<platform>/clide` (gitignored). Drop that on your PATH (or
+symlink) and `clide status` works from any directory inside a clide
+workspace once the app is running. Standard POSIX + libc only;
+pure C99; no third-party deps.
+
+The cross-language hash agreement is load-bearing — if the Dart
+server and C client disagree on the socket path, every shell
+invocation fails to connect. The test suite covers it:
+[`test/ipc/paths_test.dart`](test/ipc/paths_test.dart) pins
+FNV-1a vectors against the reference, and
+[`test/cli/clide_cli_e2e_test.dart`](test/cli/clide_cli_e2e_test.dart)
+compiles the C client and exercises the full round-trip.
+
+## Running clide from the shell
+
+Once the desktop app is running and `clide` is on your `$PATH`, every
+shell inside the workspace can drive it. The argv grammar is fixed by
+[D-6](governance/decisions/architecture.md#d-6-cli-and-event-surface-contract)
+— every UI affordance has a CLI counterpart, and every CLI verb has a
+UI affordance.
+
+```sh
+clide status                         # one-shot snapshot of pane state
+clide ping                           # round-trip health check
+clide tail --events                  # stream every subsystem event
+clide tail --events --filter git     # stream a single subsystem
+clide pane focus editor              # drive the running app
+clide panel toggle git               # show/hide a panel
+clide panel resize sidebar --to 320  # absolute width (px)
+clide panel resize context --by -40  # relative nudge (px)
+clide panel resize editor --to 0.5   # editor split ratio (0.15–0.70)
+```
+
+Output is JSON on stdout, one envelope per line. Streaming verbs
+(`tail --events`) keep the connection open and emit one event line per
+push; Ctrl-C cleanly closes the socket. Exit codes follow the pql
+convention ([D-68](governance/decisions/architecture.md#d-68-cli-and-mcp-surface-contracts)):
+
+| Code | Meaning                                              |
+|------|------------------------------------------------------|
+| 0    | success                                              |
+| 64   | user error — bad argv, unknown verb, malformed flag  |
+| 65   | data error — request well-formed but rejected        |
+| 69   | service unavailable — no running clide for this repo |
+| 70   | internal error — dispatcher threw                    |
+
+If `clide` exits 69, the desktop app isn't running for this workspace
+— start it with `make run` (during development) or launch the
+installed app pointed at this repo.
+
+### Claude Code's `/ide` and the MCP server
+
+The desktop app also runs an MCP companion server on a random
+localhost port (HTTP + Server-Sent Events, per
+[D-73](governance/decisions/architecture.md#d-73-mcp-server-transport-over-http-sse)).
+Discovery follows the Claude Code `/ide` contract: clide writes a
+JSON descriptor to `~/.claude/ide/<pid>.lock` containing the chosen
+port, the workspace root, and the protocol version. Claude Code's
+`/ide` command picks the lock for the workspace it's running in and
+connects automatically — no manual configuration. The lock is removed
+on graceful shutdown; stale locks from crashed processes are reaped
+on the next start. The implementation lives in
+[`lib/src/ipc/mcp_server.dart`](lib/src/ipc/mcp_server.dart).

+# Spike: Claude Code team / transcript internals (T-134)
+
+**Pinned to:** claude **2.1.148**, tmux **3.6a**. These are undocumented, version-drifting
+internal contracts (per D-75) — re-validate on a CC bump.
+
+**Method:** validated from real on-disk artifacts (42 past team `config.json`s, real
+team + Task-tool subagent transcripts, `.meta.json` written by the current version) plus
+a synthetic `tmux -L clide` control-mode test and the tmux manual. No live team run was
+needed to answer the questions — the existing artifacts are conclusive and cost no quota.
+
+---
+
+## Findings
+
+### 1. Teammates get tmux panes; transcripts live under `subagents/`
+- **Confirmed:** across real teams, **42 teammate members carry a populated `tmuxPaneId`**
+  (e.g. `%5`, `%120`); the lead's `tmuxPaneId` is `""`. So teammates spawn as panes and the
+  config records the pane id.
+- **Teammate transcript location:** `~/.claude/projects/<munged-cwd>/<session-id>/subagents/agent-<hex>.jsonl`,
+  with a sibling `agent-<hex>.meta.json`. `<munged-cwd> = absolutePath.replaceAll('/','-')`
+  (leading `-` kept). Note: a team's `<session-id>` dir held **0 top-level `*.jsonl`** and
+  **44 `subagents/agent-*.jsonl`** — teammate content is the subagent files, not top-level sessions.
+- Each subagent record carries `agentId` (the **hex**, e.g. `a2a3530` — matches the filename),
+  `sessionId` (the dir), `isSidechain: true`, `slug` (a random codename), `type`
+  (`user`/`assistant`/…). This is the same JSONL schema `TranscriptReader` (T-136) already parses.
+
+### 2. Lifecycle signal — control mode vs. polling
+- **tmux 3.6a control-mode notifications** (from `man tmux`): `%window-add`, `%window-close`,
+  `%window-pane-changed`, `%layout-change`, `%unlinked-window-add`, `%unlinked-window-close`,
+  `%session-changed`, `%sessions-changed`, `%pane-mode-changed`, `%exit`, `%output`/`%extended-output`, …
+  **There is NO `%pane-died`** (an-idea.md assumed one). Pane/teammate exit surfaces via
+  `%window-close` / `%layout-change` / `%window-pane-changed`.
+- **Driving control mode from code is finicky:** a `tmux -L clide -C attach` captured
+  `%session-changed`/`%exit` but the attach exited early under non-interactive Bash; reliably
+  consuming the stream needs a long-lived managed client.
+- **Polling `tmux -L clide list-panes -a -F '...'` works and is reliable** (validated: it
+  enumerated panes with pane-id/pid/title). **Recommendation for T-139: use polling as the
+  baseline lifecycle source**; treat control mode as a later optimization.
+
+### 3. Team config schema (`~/.claude/teams/<team>/config.json`)
+- Top keys: `name`, `description`, `createdAt`, `leadAgentId`, `leadSessionId`, `members[]`.
+- Member keys: `name`, `agentId` (=`<name>@<team>`), `agentType`, `model`, `cwd`,
+  `joinedAt`, `subscriptions`, `tmuxPaneId`. (Some runs also carry `backendType`/`isActive`/`mode` —
+  optional, version-varying.) The lead member has empty `tmuxPaneId`.
+
+### 4. ⚠️ Identity linkage — the real risk for T-139
+The pane/teammate identity in **config** does NOT share a key with the **transcript file**:
+- Config: `{name: gestalt, agentId: gestalt@control-interaction, agentType: gestalt, tmuxPaneId: %120}`.
+- Transcript: `agent-<hex>.jsonl` (records `agentId = <hex>`, `slug = <random>`) +
+  `agent-<hex>.meta.json = {agentType, description}`.
+- **The only join key is `agentType`** (config.member.agentType ↔ `.meta.json.agentType`).
+  This is **unambiguous only when teammates have distinct agentTypes** (e.g. `control-interaction`:
+  gestalt/ozzie/tyre/…). For **same-type teammates** (e.g. `art-requirements`: 3× `general-purpose`)
+  agentType is ambiguous → need a disambiguator: spawn order / `joinedAt` timestamp vs. file mtime,
+  or parse the **lead transcript's** teammate-spawn records (likely carry both ids). **T-139 must
+  handle this**; recommend: join on agentType, fall back to ordering by `joinedAt`/mtime, and
+  investigate the lead transcript's spawn events for an explicit hex↔name link.
+
+### 5. Resolved elsewhere
+- **Session-id discovery (check 5):** Claude doesn't expose its session id; pick newest `*.jsonl`
+  by mtime — already implemented in `TranscriptReader` (T-136).
+- **Paste (check 4):** scope to `@path` file references over `send-keys` (text channel). Clipboard
+  image paste needs an interactive display ($DISPLAY) and is out of scope for headless validation;
+  decide the composer's image handling in T-138/T-006.
+
+## Recommendations for the team tickets
+- **T-139 (observer):** poll `list-panes -a` for lifecycle; read team `config.json` for the roster
+  + pane ids; tail teammate transcripts at `<munged>/<sid>/subagents/agent-<hex>.jsonl`; resolve
+  pane→transcript via `agentType` join with a `joinedAt`/mtime tiebreaker (and confirm whether the
+  lead transcript gives an explicit link). Isolate all of this behind the one module (D-75).
+- **Re-validate on any CC version bump** — key off the transcript `version` field.
+
+## Not done
+- A **live, real-time** team run (watching a pane + transcript appear live) was not executed —
+  the static artifacts answer every question and a live run costs quota without adding certainty.
+  The one item a fresh run would pin precisely: whether the **lead transcript** records an explicit
+  teammate hex↔name mapping (would remove the same-type ambiguity). Worth a short observed run when
+  T-139 is implemented.

 - **Rationale:** One package means one `pubspec.yaml`, one `flutter analyze`, one `flutter test`, no `cd` gymnastics, no cross-package import barriers. The IPC server running in-process eliminates the daemon lifecycle (start, stop, reconnect, pid file). If the app crashes, tmux sessions survive; the app re-attaches on restart. The CLI client in C is ~100 lines (socket connect + JSON exchange) with the same contract as pql.
 - **Cost:** If the Flutter app is not running, Claude's `clide` commands fail. In practice this is acceptable — the IDE being closed means the user isn't working. A future "headless mode" could start the Flutter engine without a window if needed.

-- **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.
+- **Amendment (2026-05-19):** Both surfaces implemented in T-99. CLI lands as `IpcServer` over the unix socket (T-124, per D-70/71/72) with the C client at `native/clide-cli/clide.c` (T-126); the argv grammar lives in `lib/src/cli/argv_to_request.dart` (T-125). MCP lands as `McpServer` over HTTP+SSE (T-130, per D-73) — the transport choice closed Q-33. The two `/ide` minimum tools ship as stubs; real implementations follow as Q-32 resolves the broader tool-surface question.
+- **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 closed by [D-73](#d-73-mcp-transport-for-ide-is-sse-over-http) — SSE over HTTP. 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.
 - **Cross-reference:** [D-1](#d-1-cli-first-not-mcp) (amended — see amendment line there), [D-6](#d-6-cli-and-event-surface-contract), [D-56](#d-56-dissolve-daemon-process-flutter-app-hosts-ipc-server), [Q-32](../questions/architecture.md#q-32-mcp-tool-surface-minimum-slash-ide-or-extended-clide-tools), [Q-33](../questions/architecture.md#q-33-mcp-transport-sse-websocket-stdio-or-all).
 - **Raised by:** 2026-05-15 — consultant review (`consultants.md`) flagged the absent socket server (D-56 unimplemented) as the highest architectural drift; user chose option (a) "implement the server" and asked for MCP coverage alongside.
 
+### D-70: IPC socket path is per-workspace, deterministic
+- **Date:** 2026-05-18
+- **Decision:** The Unix-domain IPC socket served by the Flutter app (per [D-56](#d-56-dissolve-daemon-process-flutter-app-hosts-ipc-server) / [D-68](#d-68-dual-integration-surface--bash-cli-primary-mcp-secondary)) lives at `$XDG_RUNTIME_DIR/clide/<hash(workspace-root)>.sock` on Linux and `$HOME/Library/Caches/clide/<hash(workspace-root)>.sock` on macOS. The workspace root is the git toplevel (the same path the Flutter app resolved on boot). The hash is **FNV-1a 64-bit, lower-case hex (16 chars)** — deterministic, dependency-free (no `package:crypto`), matches the existing `session_naming.dart` `_hash` shape so users see one hashing pattern across clide's process boundaries. No env override. The C client (T-126) and any other consumer resolves its target socket by walking CWD up to the git toplevel and computing the same hash.
+- **Rationale:** "Repo-is-the-workspace" (CLAUDE.md guardrail) means clide instances are per-repo, so the socket must be too — a per-user-global socket would force one running clide per user and break the multi-repo workflow. The same hash on both sides ensures the shell client + the running app always agree without configuration. No env override because the deterministic path is the contract; the only reason to override is a test fixture, and tests can set `XDG_RUNTIME_DIR` to a tempdir directly. FNV-1a over a crypto hash: collision resistance isn't a security need (workspace paths are user-supplied; the path is `0600`-readable only by that user anyway); 64 bits is overkill for the cardinality (a user with 65k workspaces would still see negligible birthday collisions). Aligns with [D-41](#d-41-claude-panes-one-primary-per-repo-tmux-backed)'s tmux-socket-per-repo convention so users see one consistent pattern.
+- **Cost:** The 16-char hex prefix means socket paths aren't human-readable at a glance — `ls $XDG_RUNTIME_DIR/clide/` won't tell you which one is which repo. Acceptable; the C client never asks the user to type the path, and debugging can use a sibling `.path` file next to each socket if it becomes painful.
+- **Cross-reference:** [D-41](#d-41-claude-panes-one-primary-per-repo-tmux-backed), [D-56](#d-56-dissolve-daemon-process-flutter-app-hosts-ipc-server), [D-68](#d-68-dual-integration-surface--bash-cli-primary-mcp-secondary), `lib/kernel/src/files.dart` (workspace root resolution).
+- **Raised by:** 2026-05-18 — T-99 design pass; locked in before T-124 starts so the server + client agree on path strategy.
+
+### D-71: IPC socket access gated by chmod 0600 on socket + parent
+- **Date:** 2026-05-18
+- **Decision:** The IPC socket file and its parent directory ([D-70](#d-70-ipc-socket-path-is-per-workspace-deterministic)) are created with permissions `0600` (owner read/write only) and `0700` respectively. No token-based auth at the IPC layer; the Unix file-permission check is the only gate. Capability-scoped auth for third-party Lua/Dart extensions is a separate concern and remains tracked by [Q-1](../questions/architecture.md#q-1-authorisation-granularity) for when extensions actually need it.
+- **Rationale:** clide's threat model on a developer workstation is "another user on the same host should not be able to drive my IDE." File perms cover this exhaustively — the kernel enforces the check on every `connect(2)`, no userspace token comparison can match that. Adding a session token on top would be belt-and-suspenders without expanding the threat model. Capability tokens become useful when extensions can publish their own dispatcher routes and we want to gate which third-party code can reach which subsystem — but that's a Tier-6 concern.
+- **Cost:** Doesn't defend against same-uid attacks (a malicious process running as the user can connect). Accepted — same-uid is outside this layer's threat model; that's a sandboxing / capability concern that lives further out. Doesn't work on shared multi-user dev hosts where one socket needs to be reachable by multiple uids — clide isn't targeted at that workflow today.
+- **Cross-reference:** [D-70](#d-70-ipc-socket-path-is-per-workspace-deterministic), [Q-1](../questions/architecture.md#q-1-authorisation-granularity).
+- **Raised by:** 2026-05-18 — T-99 design pass.
+
+### D-72: IPC server is multi-connection with serial dispatch on the main isolate
+- **Date:** 2026-05-18
+- **Decision:** The IPC server ([D-70](#d-70-ipc-socket-path-is-per-workspace-deterministic)) is a multi-connection accept loop over `ServerSocket.listen`. Multiple clients (one-shot `clide <verb>` calls, a long-lived `clide tail --events` subscriber, the MCP adapter) can hold simultaneous connections. Each connection reads its own JSON-line stream asynchronously. **Dispatch through the existing `DaemonDispatcher` is serial on the main Flutter isolate** — the dispatcher walks one request at a time. Individual handlers are free to offload heavy or blocking work to short-lived worker isolates (the pattern `NativePty` and `SchedulerService` already use); the IPC layer doesn't impose that choice.
+- **Rationale:** Multi-connection at the socket layer is what every other concurrent operation in the codebase needs — `clide tail --events` (T-129) is structurally a long-lived subscription, the MCP adapter (T-130) lives on a separate connection from the CLI's one-shot requests, and parallel CLI invocations from a developer's shell shouldn't serialise on the I/O level. Serial dispatch on the main isolate is forced by the architecture, not chosen: subsystem handlers (PaneRegistry, FilesService, EditorRegistry, GitClient, PqlClient) hold mutable Dart objects + `ChangeNotifier`s the UI rebuilds from, and Dart isolates don't share heaps. A worker-isolate-per-connection design would have to ferry every request back to the main isolate via `SendPort` to actually execute — pure overhead with no parallel-dispatch gain. Per-handler isolate offload solves the only real problem (a slow handler janking the UI) without paying the isolate-safety tax across every subsystem.
+- **Cost:** A genuinely slow handler that doesn't offload to an isolate blocks the dispatch queue for all other connections until it returns. Mitigated by the per-handler offload pattern already in the codebase. Doesn't fit a future world where clide hosts headless workers (CI, batch jobs) that want true parallel dispatch — that's a different product shape and would warrant rethinking this decision.
+- **Cross-reference:** [D-56](#d-56-dissolve-daemon-process-flutter-app-hosts-ipc-server), [D-70](#d-70-ipc-socket-path-is-per-workspace-deterministic), `lib/src/pty/native_pty.dart` (per-handler isolate offload example), `lib/kernel/src/scheduler.dart` (same pattern).
+- **Raised by:** 2026-05-18 — T-99 design pass; user explicitly considered worker-isolate-per-connection and confirmed serial dispatch on main is the right shape given the shared-state architecture.
+
+### D-73: MCP transport for /ide is SSE over HTTP
+- **Date:** 2026-05-19
+- **Decision:** The `/ide`-compatible MCP server clide ships per [D-68](#d-68-dual-integration-surface--bash-cli-primary-mcp-secondary) uses **HTTP + Server-Sent Events** as its transport. The Flutter app binds an HTTP server on a random localhost port at startup, advertises itself via a discovery file at `$HOME/.claude/ide/<pid>.lock` (the format Claude Code's `/ide` command discovers), and serves: a `GET /sse` endpoint that opens a long-lived SSE stream for server-to-client JSON-RPC responses + events, and a `POST /messages` endpoint that accepts client-to-server JSON-RPC requests. Closes Q-33.
+- **Rationale:** clide's Flutter app is always-running and user-launched — the agent connects to it, not the other way around. That rules out stdio (which assumes the agent spawns the server as a subprocess). Between SSE and WebSocket, SSE wins on three counts: (a) Claude Code's existing `/ide` discovery already uses HTTP servers advertised via lock files, (b) SSE is trivially implementable on `dart:io`'s `HttpServer` (long-lived response + `data: <json>\n\n` per message — no upgrade dance, no framing), (c) JSON-RPC is fundamentally client-pushes-requests / server-pushes-responses-and-events, which maps cleanly to "POST in / SSE out." WebSocket buys bidirectional symmetry we don't need. Per [D-72](#d-72-ipc-server-is-multi-connection-with-serial-dispatch-on-the-main-isolate) the MCP layer is just another transport that wraps the same `DaemonDispatcher` — no second source of truth.
+- **Cost:** SSE requires a long-lived HTTP response. Browsers cap concurrent SSE connections per origin at 6, but the consumers here are Claude Code instances (not browsers) and one-per-workspace is the expected fan-out. Adds an HTTP listener alongside the unix socket — a small surface increase, but the alternatives are worse. Each running clide grabs a random localhost port; no contention.
+- **Cross-reference:** [D-68](#d-68-dual-integration-surface--bash-cli-primary-mcp-secondary), [D-72](#d-72-ipc-server-is-multi-connection-with-serial-dispatch-on-the-main-isolate), `lib/src/ipc/mcp_server.dart` (this transport's implementation lands in T-130).
+- **Raised by:** 2026-05-19 — T-130 design pass; user picked SSE over HTTP after weighing against WebSocket and stdio.
+
+### D-74: IPC command schema is co-registered with the handler, validated at dispatch
+- **Date:** 2026-05-20
+- **Decision:** Each IPC command may declare a **typed argument schema** (per-arg charset/regex/range constraints, required/optional, kind). The schema is **registered alongside the handler**, not authored in a central file: the `DaemonDispatcher` registration API carries an optional schema per command, and the dispatcher accumulates a `cmd → schema` registry as commands register. `DaemonDispatcher.dispatch` validates `req.args` against the command's schema **before** invoking the handler (`lib/src/daemon/dispatcher.dart`), returning a `userError` (sysexit 64) on violation so no handler sees malformed input. Built-in command modules (`registerPaneCommands`, `registerGitCommands`, …) supply their schemas at registration; extension-contributed commands ([`CommandContribution`](../../lib/extension/src/contribution.dart), Tier 6 / [D-46](tooling.md)) carry their own. The pre-existing T-104 spot-checks — `validateGitRef` in `lib/src/git/operations.dart` and the count/path caps in `lib/src/daemon/git_commands.dart` — stay in place as **defense-in-depth** below the dispatcher, because the git client is also callable directly from the Flutter UI (not only through the dispatcher). MCP `tools/list` generation from this registry is **out of scope** here — deferred to the T-130 track.
+- **Rationale:** clide's command surface is open, not fixed: every `register*Commands()` module already contributes a *set* of commands, and the extension framework lets plugins contribute more at runtime. A central static schema map (`command_schema.dart` keyed by every known cmd) cannot see extension-contributed commands and would fight the plugin model — it was considered and rejected for exactly that reason. Co-registration keeps the schema next to the code that owns the command's meaning, supports any number of independent registrants (the normal case, not an edge case), and still yields a single validation lookup at dispatch time. Validating at the dispatcher (rather than per-handler) is what makes the constraint a contract instead of a convention: a new command can't forget to validate, and the `_ResizeArgs`-style hand-lifts scattered through handlers (see `panel_commands.dart`, T-119) collapse into the schema. No third-party validation library — the constraint vocabulary is hand-rolled per the prefer-zero-deps guardrail.
+- **Cost:** A schema must be authored for each command (build-fresh — the argv parser at `lib/src/cli/argv_to_request.dart` only knows syntactic shape, never per-command argument names, so there is nothing to "lift"). Keeping `validateGitRef` + caps as well as the schema is deliberate redundancy on the git path; the alternative (single gate at the dispatcher) would leave the UI→client call path unvalidated. Until every command has a schema, validation is opt-in per command — commands with no registered schema dispatch unvalidated, same as today.
+- **Cross-reference:** [D-6](#d-6-cli-and-event-surface-contract) (CLI/Claude parity the schema enforces), [D-68](#d-68-dual-integration-surface--bash-cli-primary-mcp-secondary) / [D-72](#d-72-ipc-server-is-multi-connection-with-serial-dispatch-on-the-main-isolate) (the dispatch path being gated), [D-46](tooling.md) (extension model the central-map alternative would have broken), `lib/src/daemon/dispatcher.dart` (the validation hook), `lib/src/git/operations.dart` + `lib/src/daemon/git_commands.dart` (the T-104 checks kept as defense-in-depth).
+- **Raised by:** 2026-05-20 — T-120 design pass; user rejected the central registry as misaligned with the extensions/plugins model and confirmed co-registration with multiple command-set registrants.
+
+### D-75: Claude rendered natively from transcripts; terminal retained as general tool only
+- **Date:** 2026-05-22
+- **Decision:** clide renders the Claude conversation as **native Flutter widgets** driven by Claude Code's transcript JSONL (`~/.claude/projects/<munged-cwd>/<session-id>.jsonl`; teammate agents under `<session-id>/subagents/agent-<id>.jsonl`). The PTY/terminal emulator is **not** used to scrape or render Claude's TUI output. Claude still runs under tmux (`-L clide`) for process and session persistence per [D-41](#d-41-claude-panes-one-primary-per-repo-tmux-backed), but its *content* is sourced from the transcript file, not from the PTY stream. The terminal emulator (`builtin.terminal`) is retained and fully functional as a general-purpose IDE tool — shell sessions, build output, REPL — but it is not the Claude rendering surface. All transcript parsing is isolated behind a single reader/observer module (`lib/builtin/claude/src/transcript/`) keyed off the transcript `version` field; coupling to Claude Code internal contracts (transcript JSONL schema, `~/.claude/teams/*/config.json`, tmux control mode) is **isolated and version-pinned** (initially claude 2.1.148). **Principle ordering:** Claude-centric first; CLI-first (D-1, D-6) is a strong second. D-6 CLI/event surfaces are preserved where sensible; CLI-first no longer blocks the Claude integration.
+- **Rationale:** (a) Native Flutter rendering gives cross-widget text selection and copy — the one meaningful advantage of a terminal emulator for plain-text output, recovered in a more flexible form. (b) Removes OS-variant PTY/TUI rendering fragility (xterm escape sequences, tmux passthrough, font-metric alignment) from the Claude display path. (c) It is the substrate for surfacing tmux agent teams as real GUI panels: once the transcript reader exists, each subagent's `.jsonl` file feeds its own panel with no extra IPC. (d) Structured transcript data enables features that scraped terminal text cannot: message-level copy, per-message actions, cost/token annotation, search, diff highlighting. Accepting version-drifting coupling to CC internals is mitigated by isolation + version-pin + fixture tests: the reader module is the only file that knows the JSONL shape; bumping Claude means updating one module and running the fixture suite.
+- **Cost:** Depends on undocumented and potentially version-drifting Claude Code internals (transcript JSONL schema, subagent path conventions, `~/.claude/teams/*/config.json`). Mitigated by: (1) isolation — all parsing behind `lib/builtin/claude/src/transcript/`, nothing else touches the schema; (2) version-pinning — initial target claude 2.1.148, bumps are deliberate and tested; (3) fixture tests — golden JSONL snapshots at each pinned version exercise the reader. If the schema drifts beyond the reader's tolerance, the Claude pane degrades gracefully (shows a parse-error banner with the raw transcript path) rather than crashing.
+- **Cross-reference:** [D-1](#d-1-cli-first-not-mcp) (CLI-first preserved as strong second), [D-6](#d-6-cli-and-event-surface-contract) (CLI/event surfaces preserved), [D-41](#d-41-claude-panes-one-primary-per-repo-tmux-backed) (tmux process persistence unchanged), [D-56](#d-56-dissolve-daemon-process-flutter-app-hosts-ipc-server) (Flutter app hosts in-process). Implemented by epic T-132.
+- **Raised by:** 2026-05-22 — native Claude integration epic (T-132); user set Claude-centric > CLI-first ordering.

+///   correlating live pane ids with `tmuxPaneId` gives a dependable
+///   joined/left signal and full identity — no transcript needed.
+/// - **Fragile — per-teammate transcript join.** A teammate's transcript is
+///   a subagent file `<munged-cwd>/<leadSessionId>/subagents/agent-<hex>.jsonl`
+///   whose only ids are a random hex (the filename) and a `slug`; it carries
+///   no `name`/`agentType`. The config's `agentId` is `<name>@<team>` — a
+///   different namespace — so there is no shared key. We join via a sibling
+///   `agent-<hex>.meta.json` (`{agentType}`) when present, else fall back to
+///   zipping members-by-`joinedAt` against files-by-mtime. This is the part

+/*
+ * clide — thin C client for the in-process IPC server hosted by the
+ * Flutter app (T-99 / T-126). Third slice of D-56 path (a).
+ *
+ * What it does:
+ *   1. Walks CWD up to a directory containing `.git` (the workspace
+ *      root, same definition the Flutter app uses on boot).
+ *   2. Hashes that path with FNV-1a 64-bit and resolves the per-
+ *      workspace socket path per D-70 (Linux: $XDG_RUNTIME_DIR/clide/
+ *      <hash>.sock; macOS: $HOME/Library/Caches/clide/<hash>.sock).
+ *   3. Connects, sends `{"v":1,"type":"request","id":"<pid>",
+ *      "cmd":"_argv","args":{"argv":[...]}}` (the server runs
+ *      parseArgv on it per T-125), reads the JSON-line response,
+ *      writes payload to stdout, error message (if any) to stderr,
+ *      exits with the response's exit code.
+ *
+ * Design notes:
+ *   - No third-party deps. Standard POSIX + a minimal JSON writer
+ *     (string-escape only — we never PARSE JSON, just emit argv into
+ *     it; the response is read whole then printed as-is to stdout).
+ *   - The argv→IpcRequest translator lives in Dart (T-125). We just
+ *     ship argv across the wire under a sentinel cmd `_argv`; the
+ *     server unpacks it.
+ *   - Workspace-root discovery: we look for `.git` (dir OR file —
+ *     submodules use a file). If we don't find one walking upward,
+ *     exit with EX_USAGE.
+ *
+ * Build: `make clide-cli` (see Makefile). Pure C99, builds with
+ * any gcc / clang / cc.
