add panel.resize CLI verb (T-119)

The keyboard half of panel resizing landed in T-111 (arrow-key
splitters); this completes D-6 user/Claude parity with a CLI verb now
that T-99's IPC dispatch path exists. `clide panel resize <slot> --to N`
sets an absolute pixel size, `--by N` nudges relative to current, and
the reserved `editor` slot drives the editor/bottom-panel split ratio.

The handler lives in panel_commands.dart and stays Flutter-free (so
test/daemon/ keeps running under `dart test`) by talking to an abstract
PanelResizer; the kernel bridge in panel_resizer_kernel.dart wraps
LayoutArrangement and reuses T-111's bumpedSlotSize so the CLI's
relative deltas honour the same right-edge sign-flip as the drag/arrow
handlers. Arguments are lifted from both the direct call shape and the
argv-translator's positional/flags shape pending the typed schema in
T-120. The daemonClientFactory now receives the LayoutArrangement so
the dispatcher can reach it.

+`pubspec.yaml` is the single source of truth for the version. 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.

+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.

+
+Re-scope (2026-05-19, post T-99): the wire contract is now real — IpcRequest envelopes flow over the unix socket (per D-70/71/72) and through the C clide client which serialises raw argv under the `_argv` sentinel (per D-72/D-6). The argv parser (lib/src/cli/argv_to_request.dart) is the de-facto schema today; T-120 should formalise it by:
+
+- Lifting the per-cmd grammar from argv_to_request.dart into a typed registry keyed by cmd, sharing it with both the argv parser and the dispatcher.
+- 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.

+
+- Lifting the per-cmd grammar from argv_to_request.dart into a typed registry keyed by cmd, sharing it with both the argv parser and the dispatcher.
+- 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.

+- Where the schema lives (per-handler? central registry?).
+- Whether it generates handler boilerplate or wraps existing handlers.

 ### Added
 
+- `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,

+## 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

+### 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).

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.

 ### 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.
+- **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.

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.

+/*
+ * 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.
