The TUI keyless smoke exposed the wrong idle signal: /plan submitted while
the driver is between turns still saw status running (checkpointing), so
the selection queued and the immediate copy never appeared. The commit
gate is now the log's own open-turn fold — plan/mode commits at once
whenever no turn is open, and queues only inside one. Specs drive the
distinction through explicit turn/start / turn/end events instead of a
fake status; the keyless smoke pins the new idle copy on both /plan and
/plan off; regenerated cordis/service catalogs ride along.
The idle /plan and /plan off command paths pin the immediate-commit copy;
the chip's dead leaving/locked guard is deleted (both states disable the
button, so no click reaches the handler); the multi-turn TUI golden is
re-recorded keyless over the idle-commit wording and the standalone
plan/mode narration ordering.
set() on an idle agent appends plan/mode at once — no request boundary
would arrive until the next prompt, so a queued intent used to hang as
pending forever (the composer showed a dead pending target). A running
agent keeps the boundary-flush path unchanged. set() now reports which
branch ran (committed/queued/cancelled/noop); the /plan handler's copy
follows the branch (idle: "Plan mode on/off", mid-turn: the next-step
wording), and both commit paths share the header-delta narration. The
invariant drops turn enclosure: plan/mode is a standalone whole-value
event (the synthetic log-only turns removal already established the
between-turns append shape). The fixture mirrors the idle commit.
CommandService.execute now returns a CommandExecution — the normalized
result plus the commandId minted for its command/run/command/done records —
and the wire admission value carries commandId exactly when matched, so the
issuing client can correlate its RPC acknowledgment with the flow node the
lifecycle events produce. apiproxy api/schema/handler, the connection
fixture, and the TUI/plan/goal consumers follow the new shape.
CommandService.execute appends the log-only pair around every resolved
handler — run before invocation, done at settlement, including thrown and
aborted handlers (kind:'error'); admission misses log nothing. commandId is
minted monotonically per instance; per-session appends serialize through a
tail queue over SessionStore.appendOutOfBand (zero-step wrap on an idle log,
direct join inside an open turn). The invariant companion now asserts the
pairing relation (unique run ids; a done requires a prior in-log run).
CommandSource is a minimal merge-extensible map (user variant only).
Dependent benches mount SessionStore; TUI/e2e snapshots re-recorded for the
executor's durable-append timing and the /status event counts.
Prompt admission runs before any turn opens, so the agent/prompt-submit
flush listener could only ever append plan/mode outside an open turn —
invariant-vetoed and retried at agent/step when the session invariant is
mounted, silently out-of-turn in the durable log when it is not. agent/step
fires inside the open turn before every request derivation (including
turn 1 step 1), so it is the sole flush point and no behavior is lost: a
pending idle switch lands as the first step's in-turn plan/mode. Tests pin
the new contract: admission never appends; the first step boundary flushes.
run_code gains a required bash-style description parameter: presentCall
titles the card with it and moves the program to rawInput, so every
surface gets a readable label. tool/code-dispatch now logs each
sub-call's complete content/isError (the tool/result vocabulary),
replacing the bounded resultSummary and deleting the summarize/cwd
machinery — a UI renders sub-calls through the identical path as native
results. The dsh config tree mounts the worker code runtime and reads
DSH_TOOLS_MODE (temporary seam until per-session mode selection lands).
Session format stays v0 (pre-release churn). Code-mode ACP/TUI fixtures
re-recorded; TUI presenter pin refreshed; catalogs regenerated. Keyless
web smoke pins the code-mode wire contract (tools=[run_code] + SDK
prompt section).
Replace send/steer/inject with one Agent.send primitive over the
(target × wakeup) matrix; followup/steer/inject become fixed-preset
alias methods on the now-abstract Agent class. Coalesce context/message
into user/message (injected context is a non-user source). Replace
agent/queued with agent/inbox/enqueue/dequeue/discard, add cancel
keepInbox, and add a FIFO-conservation invariant.
