The UI's backend client connected straight to the workspace unix
socket, hard-coding the local shape. It now talks JSON-lines through a
DaemonTransport (new lib/src/ipc/transport.dart, Flutter-free), with
LocalSocketTransport reproducing today's connect byte-for-byte — zero
behavior change, proven by the untouched client test suite plus new
seam tests driving the client over an in-memory transport.
This is the slot the SSH-remote backend (T-329/Q-23) plugs into:
request correlation, reconnect/backoff, and event forwarding live
above the seam and won't change when the endpoint is remote.
main.dart's swapIpcServer becomes swapBackend per the same plan.

The async onData handler never paused its subscription, so pipelined
requests interleaved mid-handler — violating D-72's serial-dispatch
contract — while the shared StringBuffer could re-frame underneath an
in-flight await and the per-chunk utf8.decode corrupted runes split
across reads. One `await for` over a persistent Utf8Decoder +
LineSplitter fixes framing, decoding, and serialization at once.
Tests: two frames pipelined in one write dispatch strictly in order;
a frame split mid-rune across writes decodes intact.

D-71's threat model — another user on the same host must not drive my
IDE — was enforced with 0600 on the unix socket and then bypassed
wholesale by the unauthenticated localhost SSE port, which since D-86
serves every clide verb as a tool. The server now mints 32 bytes of
CSPRNG token per start, publishes it via the /ide discovery lock
file's authToken slot (the field Claude Code's client reads), chmods
the lock to 0600, and rejects any request that doesn't present the
token in x-claude-code-ide-authorization with 401.

Raise the declared minimums in pubspec.yaml to what our deps already
require: Flutter >=3.35.0 / Dart >=3.9.0 (was 3.19.0 / 3.5.0). alchemist
0.12 needs Flutter 3.32; Dart 3.9 first ships in Flutter 3.35, so 3.35 is
the binding floor. Pin the exact build toolchain in .fvmrc (Flutter
3.44.1).
Moving to the Dart 3.9 language level switches `dart format` to the new
"tall" style and enables two new lints. This commit is the resulting
mechanical churn, isolated from any behaviour change:
- whole-tree `dart format` reformat (tall style)
- `dart fix` for unnecessary_underscores + use_null_aware_elements
No runtime behaviour change; `make test` green.

External MCP clients (Cursor, Windsurf, Copilot) can now drive clide. The
MCP server's tools/list is generated from the co-registered command+schema
registry (D-74) that already feeds the CLI and palette — the full
mcp__clide__* namespace with no hand-maintained second surface (D-86). Each
command's CommandSchema maps to a JSON-Schema inputSchema; tools/call routes
mcp__clide__<cmd> to dispatcher.dispatch and renders the IpcResponse as MCP
content (data as JSON, errors with isError).
register() gains a mcpExpose flag (default true); pane.tail opts out as a
poor request/response fit. tail/events are server-intercepted so they're
naturally absent. The two /ide stubs (getDiagnostics, executeCode) are left
as stubs — making them real (analyzer hook, Jupyter eval) is out of scope
per the ticket. Transport unchanged (SSE, D-73).

The one-shot request/response complement to the never-returning
`tail --events` stream — what an agent poll loop wants. The IPC server now
keeps a single global, arrival-ordered event log keyed by a monotonic
cursor (alongside the per-subsystem replay ring), bounded by eventLogDepth
with drop-oldest back-pressure (D-85: producer never blocks).
`clide events [--since <cursor>] [--filter X]` returns events after the
cursor, a high-water `cursor` to poll from next, and `gap: true` (+
oldestCursor) when the requested cursor predates the retained window so a
caller detects loss instead of silently missing dropped events. Repeated
polls neither drop nor duplicate. No on-disk persistence.
`events` is handled in the IPC server like `tail` (not the dispatcher);
added to the argv umbrella set. bindingWhen/CommandContribution untouched.

Per D-74: commands register an argument schema beside their handler
instead of hand-validating args inline. DaemonDispatcher accumulates a
cmd->schema registry and, before invoking a handler, normalises the
argv-translator shape ({positional, flags}) into named args, coerces
types, and checks per-arg constraints (charset/pattern, leading-dash
rejection, numeric range, list caps). Violations return userError so no
handler sees malformed input. Schema adoption is opt-in per command —
unschema'd commands dispatch unchanged.
panel.resize adopts a schema (dropping the _ResizeArgs hand-lift from
T-119); git.checkout and git.push gain schemas that reject leading-dash
refs at the dispatcher and, via positional ordering, fix the C-client
CLI path — `clide git checkout <branch>` now reaches the handler, where
the positional token previously never mapped to `branch`. The T-104
validateGitRef + count/path caps stay in place as defense-in-depth
because the git client is reachable directly from the UI, not only
through the dispatcher.

Seventh slice of T-99. clide now advertises itself to Claude Code's
/ide command and serves a working MCP endpoint over HTTP+SSE per
D-73 (the Q-33 transport decision, locked in this commit).
What lands:
* D-73 — MCP transport for /ide is SSE over HTTP. Resolves Q-33;
references D-68 + D-72.
* lib/src/ipc/mcp_server.dart — McpServer class. localhost HTTP
listener on a random port; GET /sse opens a long-lived SSE stream
with an initial endpoint event carrying the session id; POST
/messages?sessionId=... accepts JSON-RPC requests and replies via
the matching SSE stream. JSON-RPC handlers for initialize,
tools/list, tools/call.
* Discovery file at $HOME/.claude/ide/<pid>.lock with the workspace
+ url so `/ide` can find us. Removed on stop.
* The two /ide minimum tools (mcp__ide__getDiagnostics,
mcp__ide__executeCode) ship as stubs — real implementations need
the analyzer integration / a clide eval surface, both follow-ups.
* main.dart starts the MCP server alongside the unix IPC server on
daemonClientFactory and project switch. Failure non-fatal — the
UI runs without MCP.
* 12 server tests cover lifecycle (start/stop, lock file), unknown
paths, full JSON-RPC round-trip for all four methods, error
responses, and edge cases (unknown session, malformed JSON,
notification without id).
The "Claude Code's /ide discovers and connects" smoke is deferred to
T-131 wrap-up since it needs a real Claude Code session against the
running app — out of scope for unit/widget tests.

Two extra cases at the server layer that the dispatcher-level tests
don't reach: _argv carrying tail --events should route into the
streaming check, and _argv with non-list args should surface a
userError via the server's write path (not the dispatcher's). Lifts
coverage back over 95.

Sixth slice of T-99. Long-lived event subscription path, the second
half of D-6.
Wire shape:
- Client sends `{cmd:"tail", args:{flags:{events:true, filter:X}}}`.
- Server responds with `{ok:true, data:{streaming:true, filter:X}}`.
- Server pushes `{type:"event", subsystem, kind, ts, data}` lines
until the client closes.
Server (lib/src/ipc/server.dart):
- Takes a DaemonBus, subscribes to DaemonEvent on start.
- Per-subsystem ring buffer (replayDepth=16 per D-6) populated on
every emit.
- `tail --events` connection: send ack, replay matching events from
ring, register the client for future fanout.
- _argv envelope now unwrapped at the server layer so the streaming
check sees the inner `tail` cmd (not just `_argv`).
- Broken subscriber writes drop the subscriber cleanly; the bus
doesn't block on a stalled client.
Client (native/clide-cli/clide.c):
- Sniffs `data.streaming:true` in the ack. If set, loops reading
JSON-line events to stdout (with fflush per line) until EOF.
Tests:
- test/ipc/server_streaming_test.dart — 8 cases covering ack shape,
filter, replay buffer (size + ordering), multi-subscriber fanout,
broken-subscriber cleanup.
- test/cli/clide_cli_e2e_test.dart gets a tail --events test that
spawns the C client, emits two events on the bus, asserts they
print on stdout.
T-99 children remaining: T-130 (MCP), T-131 (wrap-up).

Third slice of T-99. After this `clide status` actually does
something when typed in a shell.
* native/clide-cli/clide.c — ~250 LOC C. Walks CWD up to .git,
hashes the workspace root with FNV-1a 64-bit (byte-for-byte
identical to the Dart side, pinned via reference vectors in
paths_test.dart), opens the per-workspace socket, and ships argv
across the wire as `{cmd:"_argv", args:{argv:[...]}}`.
* lib/src/cli/argv_dispatch.dart — registers the `_argv` sentinel
command on the dispatcher. The handler runs the T-125 parser on
the embedded argv and either re-dispatches the unwrapped request
through the same dispatcher or returns the pre-built error
response. Keeps the parser in Dart so the C side stays dumb.
* lib/src/ipc/paths.dart — fnv1a64Hex hoisted to a public helper +
fixed to format as unsigned (Dart `int` is signed int64; the high
bit lit a leading minus that broke the cross-language compare).
Reference-vector tests added against the FNV reference.
* `make clide-cli` builds it via the host `cc`; output lands at
native/<platform>/clide and is gitignored. Test
test/cli/clide_cli_e2e_test.dart compiles + exercises the full
round-trip; skips cleanly when no cc is on PATH.
* CONTRIBUTING.md gets a "C clide shell client" section.
T-128 (delete legacy IPC) unblocked.

Previous follow-up only proved the existing-dir branch on this host
because the dir was already there. Now the test deletes the parent
when it's safe to do so (exists + empty) so the create-if-missing
branch fires and counts toward coverage.

socketPath-before-start + prepareParentDir-creates-missing — adds

Net new uncovered lines in lib/src/ipc/server.dart from the T-124
commit (handler-throw → toolError, non-request → userError, in-flight
client teardown on stop, multi-request on one connection) are covered
here so the coverage gate holds at 95%.

First slice of T-99 (the D-56-path-a IPC server). What this lands:
* lib/src/ipc/paths.dart rewritten — `workspaceSocketPath(root)`
returns the per-workspace path per D-70 (FNV-1a 64-bit hash, hex,
no crypto dep — D-70 amended in this commit to record the hash
choice). Old `defaultSocketPath()` removed; the lone fallback in
facade.dart kept with a clear placeholder pending T-127.
* lib/src/ipc/server.dart — IpcServer class. ServerSocket.listen
accept loop (D-72), 0600 socket + 0700 parent (D-71), stale-node
probe + unlink on start, refuses to clobber a live listener.
* lib/main.dart — IpcServer started after the first dispatcher is
built and swapped on project open (workspace path changes).
Failure logged but non-fatal so the UI still works without IPC.
* 11 server tests + 5 path tests cover socket modes, multi-conn,
stale unlink, live-conflict, idempotent start/stop.
T-99 children downstream of T-124 (T-125 / T-126 / T-127 / T-130)
are now unblocked.

pane.spawn (via PtyException.errno) and editor.open (via
FileSystemException.osError.errorCode) now route ENOENT to
not_found, EACCES/EPERM to user_error with a permissions hint,
EISDIR/ENOTDIR/EEXIST to distinct user-error/conflict, and
EMFILE/ENFILE to tool_error with a "fd limit hit" hint. The
mapping lives in lib/src/ipc/errno_mapping.dart so other handlers
can adopt the same surface as they pick up errno-bearing failures.

First real content for the `clide` Dart package at the repo root.
One AOT-compiled binary (ADR 0005) with two modes:
* `clide --daemon` long-running unix-socket server; listens on
`$XDG_RUNTIME_DIR/clide-$USER.sock` with stale-socket
reclaim, accepts JSON-lines request/response traffic, clean
SIGTERM shutdown unlinks the socket file.
* `clide <subcommand>` one-shot; opens the socket, sends a
request, writes the response JSON to stdout, exits with the
dispatcher's error code per ADR 0006 (0/1/2/3/4). Unknown
subcommands forward to the daemon so extensions can register
their own without CLI changes.
Tier 0 handlers: `ping` (returns pong + version + UTC ts) and
`version`. Both are covered by `test/ipc/` + `test/daemon/`; the
subprocess test builds `bin/clide`, starts it, pings it, SIGTERMs
it, and asserts the socket file disappears.
