* perf(pa-tui): handoff exits break the run loop this iteration - chat->agents 119ms -> 67ms (#2893) The terminal loop's exit-key break only left the input-drain loop, so the handoff fell into the select below it and parked on the 50ms idle tick before the loop-tail exit check ran — measured as ~50ms of added latency on every chat -> agents view switch (strace: the key is handled in ~0.1ms, the teardown starts on the next tick wake ~51ms later; the code's own comment already demanded the teardown run "this iteration"). A handoff (agents-back, /resume, the scoped view, /resume <selector>) now breaks the outer loop immediately: the next surface's mount clears the alt screen, so the tail pass paints nothing the user can see. A non-handoff exit (/exit, /quit) keeps the tail pass — its frame gate paints the final chat frame the exit's main-screen flush shows — and headless runs keep the tail pass so captured frame sequences stay identical. * perf(pa-daemon): borrow message content as RawValue - kill the second full catalog parse, cold -25% (#2882) Co-authored-by: perf-catalog-second-parse-fast <hillclimb@local> * pa-daemon: agent_engine.rs split 1/11 - the tests concern moves out of src/agent_engine.rs (#2889) 51bd18583e17merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * perf(pa-cli/pa-daemon): tighten the two cold-open connect-probe grids from 25ms to 5ms (#2891) Cold-open boot-floor decomposition at 7064d039a (bench hillclimb record 20260926-194800-startup-boot-floor-decompose) measured two pure-wait probe grids on every cold launch, each quantized 0-25ms (mean ~12.5ms): - ensure_daemon_running_with polls the freshly spawned supervisor's socket every 25ms; a cold supervisor binds ~39ms after spawn. - probe_worker_socket polls a freshly forked session worker's socket every WORKER_CONNECT_BACKOFF_MS=25ms; the worker binds ~1-3ms after the fork. Both grids tighten to 5ms.

Mirror the merged #2872 session-memory pattern on the two daemon-side phase boundaries: write_line reports the serialized byte count and the client write loop trims when a routed line carried >=1MiB (the frame is out and the tree is dropped first), and the saved-session scan trims at its join (the per-line trees are folded and freed inside the blocking task; the per-file cached scan states are live cache and stay untouched).

The Rust engine is threaded: two worker threads racing AuthStorage::create on a fresh session's first turn (model-resolution registry build vs a concurrent auth read, strace-verified: openat O_CREAT|O_EXCL -> EEXIST within 47us, loser clock_nanosleeps the full 20ms) pay the TS retry sleep against each other, a ~20ms first-turn latency class in 4/6 msgsettle trials. A process-local mutex keyed by the auth document path serializes same-process callers for the microseconds the small read/modify/write holds. The file protocol, staleness judgment, and retry semantics are untouched: a foreign holder (another process) still surfaces WouldBlock and still takes the 10x20ms retry. The mutex is a leaf (the locked section performs only the document's own fs ops plus the caller's callback; no callback re-enters with_lock), and poisoning is recovered because the file protocol is the correctness mechanism.

The Rust ring evaluated it at RECV time in every connection event arm - a superset in the attach/detach race window TS cannot produce (an event published before an attach could still land after it, duplicating a row the attach snapshot already carried). Session events now route through a supervisor-side subscriber index (session id -> connection id -> bounded per-connection queue): publish enqueues to the attached set under one lock, unattached connections never wake (the ~5.9us/session/append wakeup floor at N=100 from the concurrent-io lane), per-(session,connection) order stays publish order, and a full queue drops with a one-line-per-stall-cycle log (finding 4a visibility). Broadcast / BroadcastExcept / RosterSubscribers keep the ring; ClientRouting::AttachedSession is removed so a stale session-event publish fails at compile time. Session events without an active session id are dropped (TS l.6296 !activeSessionId guard), not broadcast.

A 2600-key scroll walk over the canonical 10MiB session retained 5,428 entries' rows as 604k fragment-sized spans holding 5.2MB of text (+64.6MB heap, fully retained after return-to-tail; the tui-scroll-retain census: 8.3 spans/line, content capacity already exact, 44% line-buffer slack, per-span Vec/String chunk overhead the retained mass). Merging adjacent same-style spans would shrink the storage but changes the exit-flush inline scrollback's ANSI bytes (per-span SGR re-emission; the exit flush is the TS-parity-frozen output), so the cache stores the same rows packed instead: one content blob plus dense (offset, len, style) records, expanded byte-exactly on read - only the intersecting row range is expanded, so a frame inside a huge entry pays its visible rows, never the whole row set. The pad entry's own 109k-span row set (the resumed ready-state footprint) packs the same way. * perf(pa-tui): exact pack blob capacity + size-gated post-pack trim The pack's blob grew by String doubling (2x capacity: 33.6MB held for a 17.45MB row set at 40MiB); the first pass now sizes it exactly. A huge entry's rendered rows are the transcript's biggest single transient and the pack just freed them - the freed pages only return to the OS when the allocator's trim can reach them (the 40MiB ready RSS measured bimodal 181/205 on the same build); the pack now returns them immediately, gated at 8192 rows so ordinary entries never pay a trim. * fix(pa-tui): EntryRows::is_empty for the touch surface's shows-tail peek (fold resolution completion) The #2911 fold introduced the empty-section peek (a window that exactly ends on the final chat entry re-checks whether any non-empty section remains before declaring shows-tail); its section source is the EntryRows handle since the packing fold, which needs the is_empty form. * test(pa-tui): fix the pack tests' clippy findings (untyped Vec::new, shadowed view helper) * test(pa-tui): drop the pack test closure's unused mut --------- Co-authored-by: perf-tui-scroll-retain-fast <perf-tui-scroll-retain-fast@hillclimb.local> * pa-daemon: agent_engine.rs split 2/11 - the config concern moves out of src/agent_engine.rs (#2909) 07cbb0febb74merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-daemon: agent_engine.rs split 4/11 - the model concern moves out of src/agent_engine.rs (#2907) 5c530e66cef9merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-tui: session_ui.rs split 3/14 - the queue concern moves out of src/session_ui.rs (#2900) e673275046dfmerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-daemon: supervisor.rs split 7/8 - the update/restart concern moves out of src/supervisor.rs (#2903) 268c1fba26c0merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-tui/pa-cli: dock panel exits restore the dock's own group, not the prompt bar (operator ruling 2026-09-26) (#2864) a12c2847335bmerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-daemon: agent_engine.rs split 5/11 - the goalcore concern moves out of src/agent_engine.rs (#2924) c95a239b9eb3merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * perf(pa-tui): handoff drains park on observed input, not a fixed wait - chat-to-agents -79% (#2916) * perf(pa-tui): a handoff drain consumes buffered input instead of parking on the idle window The chat->agents handoff teardown pays the enhanced_keys drain's fixed 50ms DRAIN_IDLE poll on every switch (chat->agents measured 67ms p50 at #2893, ~50ms of it this window). The idle window guards a kitty key release that lands after raw mode is off - a leak that is unreachable on a handoff: raw mode stays on (the adopting surface's reader takes the same tty) and every surface's dispatch drops release events (input::filter_enhanced_key_events, TS tui.ts). The handoff now consumes what the terminal has already written with zero-timeout polls and returns as soon as the buffer is observed empty; only when input IS flowing does it fall through to the bounded drain, so a burst around a handoff is coalesced exactly like before. True exits (drain, drain_for_exit) keep the TS drainInput(1000, 50) contract untouched. Adds a real-pty e2e that arms the kitty protocol, injects the handoff trigger's release in flight, and audits the byte stream (no visible release, no post-exit kitty flags, no echo after the restore). * test(pa-cli): fix the kitty-release e2e gate lints (fmt shape, unit let-binding, unused import) * test(pa-cli): the kitty-release mock supervisor serves every connection in turn The chat surface holds one daemon connection and the agents view opens its own after the handoff; a single-accept mock refused the second (the first run of the e2e failed on exactly that: connection refused at run_agents_view connect). * test(pa-cli): qualify the mock supervisor connection handler call * test(pa-cli): handle the listener incoming result in the mock supervisor * test(pa-cli): the kitty-release editor probe waits for the painted cell The frame paints typed cells as styled positioned cells (escape bytes between characters), so the two-byte zz needle never appears; wait for the painted z cell instead. * test(pa-cli): the kitty-release harness reaps the pty child on panic paths too * test(pa-cli): the kitty-release exit drives the CSI-u escape form With disambiguate armed a kitty terminal encodes its Esc presses as CSI 27 u; the raw lone ESC byte is the legacy form the reader arms its meta-wrapper hold for. Drive the realistic encoding and separate the exit key from the release injection. * fix(pa-tui): the handoff drain's bounded phase runs on the budget the zero-timeout loop left The zero-timeout consume loop can spend the whole DRAIN_MAX under continuous input before falling through to drain_until_idle, which then started a fresh budget - the handoff could block nearly two seconds, past the documented one-second hard cap. The bounded phase now runs on what remains of the original budget (Macroscope thread PRRT_kwDOSXZbXs6mWWqM). * perf(pa-daemon): borrow the catalog fold metadata and single-open the scan - cold scan -7%, syscalls -22% (#2919) * perf(pa-daemon): borrow the catalog fold's entry metadata, kill the per-line tail Vec The post-#2879/#2882 cold roster scan still typed-parsed every line into owned strings and materialized `Value` trees for fields the fold reads once or discards: 3 `String` allocations per line (type, id, timestamp) plus a `Value` tree per message row (role, provider, model, timestamp) and per session_info/state/model_change/thinking_level row. The resume tail added one `Vec` allocation per line sized line.len()+17 to keep 16 bytes. Both costs are gone without changing a row byte: - SessionInfoEntry's scalar fields borrow as `Cow<str>` (zero-copy when unescaped, owned fallback identical to the old String), its object fields ride raw spans like #2882's content: each arm parses back only the span it reads, with exactly `Value::as_str`/`as_u64` semantics (present-and-string/number, absent and non-string both read None, the model_change abort arm keeps its exact two-step None). - advance_tail copies inside the fixed 16-byte window: the same bytes (a rolling-reference lockstep test pins the old Vec semantics), no per-line allocation. Differential ground truth: the new in-tree shape matrix pins every borrowed read to the full-parse Value read per row (escaped scalars, non-string roles/timestamps, null/absent/whitespace names, hidden/sleep states, abort shapes) and folds the accepted rows end to end against the legacy full-parse reference fold; the VM census ran the same differential over 177,798 real fixture lines (100/1000/4096 tiers) with zero divergence in acceptance, fields, or fold states both directions. * perf(pa-daemon): share one open between the roster header gate and the fold The roster scan opened every file twice: the bounded header gate opened, read its first line, and closed, then the fold opened the same path again for the scan — an openat+close per file per scan (plus the second metadata read the fold always paid). The gate now reads the first line from the same fresh handle the fold rewinds and scans, so one open serves both. The TOCTOU the double-open carried is disclosed: with two opens, a rename/replace landing between them judged one file and folded another; the shared handle pins the judgment and the fold to the same inode — the fold's cursor, generation, and certification re-stat now read the file the gate judged, never a replacement that raced in between. The listing stat (`stats.mtime`, the `modified` fallback of last resort) is read lazily now: the fold only reaches it when a row has neither message timestamps nor a parseable header timestamp, so the eager per-file stat the scan always paid serves only the rows that read it.

The auth-lock cycles 150-300us same-process serialization was pacing the threads apart by accident; that masking is not a mechanism to keep. TS runs its synchronous settings lock single-threaded, so same-process settings contention is a Rust-port artifact, the exact class #2915 ruled on for the auth lock: a process-local mutex keyed by the document path serializes same-process callers for the microseconds the small read/modify/write holds. The file protocol, staleness judgment, and retry semantics are untouched: a foreign holder (another process) still surfaces WouldBlock and still takes the 10x20ms retry. The mutex is a leaf (the locked section performs only the document's own filesystem operations plus the caller's update callback; no settings callback re-enters with_lock - every callback is a pure JSON transform), and poisoning is recovered because the file protocol is the correctness mechanism. --------- Co-authored-by: perf-auth-lock-fast <hillclimb@prime-intellect.ai> * perf(pa-daemon): zero-copy worker response path - routed msgs -17%, attach -22%, worker RSS -20% (#2935) * perf(pa-daemon): zero-copy worker response handoff - serialize the line from the borrowed trees, write the frame without re-buffering the payload * fmt(pa-types): the segments test write_frame call in the form CI rustfmt wants * fmt(pa-daemon): the response-path call forms CI rustfmt wants (VM cargo fmt at the exact head) * fix(pa-daemon): restore the response_line TS-key-order test the new-test insert orphaned (clippy empty_line_after_doc_comments was the symptom) * fmt(pa-daemon): the restored test doc comment indent * fmt(pa-daemon): single trailing newline at file end --------- Co-authored-by: wc <wc@fleet.local> * pa-daemon: agent_engine.rs split 6/11 - the Turn types move out of src/agent_engine.rs (#2931) b2ca4deea5afmerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * perf(pa-daemon): batch the queue-checkpoint journal pair - 4 syncs per warm turn to 2, crash window strictly narrowed (#2936) * perf(pa-daemon): batch the queue-checkpoint journal pair into one durable append The queue checkpoint (prompt/steer/follow-up admission, turn settle, queue mutations) appends two records to the worker recovery journal - the queue snapshot and the busy/operation verdict - as two separate open+write+fsync cycles, paying two journal flushes per checkpoint. Both records describe one atomic checkpoint, and the busy verdict must never publish over a snapshot that did not persist, so the pair can ride ONE open+write+fsync: the batch is all-or-nothing durable, the on-disk line order matches the sequential form exactly (snapshot first, then the verdict), and an unchanged verdict keeps appending the snapshot alone. Measured on the warm-turn admission path (the wave-5 warm-durable-append decomposition): the two journal fsyncs sit inside the TUI-ack-to-user-row phase together with the session append's fdatasync; batching removes one of the three durable syncs per warm turn without weakening any durability guarantee (the session append's per-row fdatasync is untouched). * test: rustfmt the batched-checkpoint test call sites (gate fmt finding) * fix(pa-tui): the exit watchdog holds fire while the flush drains - healthy slow drains no longer truncate scrollback, TS-convergent (#2937) * perf(pa-tui): the exit guard holds its force-quit while the exit path drains - slow terminals keep the whole scrollback flush On a terminal that consumes the exit flush slowly (a laggy ssh at ~0.5-2MB/s), the flush of a large transcript outlasts the 1500ms FORCE_QUIT_AFTER_MS deadline that arms at the second Ctrl+C, and the watchdog fires mid-flush: strace shows its restore writes winning the pty FIFO race at a flush-chunk boundary, exit_group(0) landing while the writer still holds ~64-82% of the transcript (40k rows: 8.74MB flush truncated to 1.5-3.1MB), 'shutdown stalled; forced exit.' printing on a healthy drain, and the restore bytes queueing mid-stream behind the flushed rows. TS has no watchdog at all (its handleCtrlC second press runs the async shutdown, and slow writes simply wait), so both the message and the truncation are port-only. The guard becomes drain-aware: the flush writer reports progress per completed 32KiB chunk (view.rs FlushSink), the release tail and the resume hint report theirs, and the watchdog holds its fire while progress landed within EXIT_PROGRESS_GRACE_MS (500ms) - the hard 1500ms ceiling stays for the silent case (the wedged loop the guard was built for). Flush chunks shrink 256KiB -> 32KiB so a drain of at least ~65KB/s completes chunks inside the grace window; the flush byte stream is unchanged (the exit-flush lane's byte-identity oracle). The truncated scrollback contract is restored on slow drains: the flush completes byte-identically, the release tail lands after the last row, and the message prints only for a genuinely stalled drain. The exit-guard unit tests grow the hold/fire decision table; a new real-pty e2e (pa-cli slow_drain_exit_guard_e2e, the kitty-release harness pattern) drives the real chat surface over a paced pty master and asserts both sides: a draining terminal flushes the whole transcript with no forced exit, and a stalled drain still fires. Rider (disclosed): kitty_release_handoff_e2e grows the restore_dock_focus field the #2916 squash dropped from its fold-time heal - the tip's pa-cli test target does not compile without it. * test(pa-cli): the slow-drain e2e asserts the forced fire structurally The re-executed test binary's libtest harness captures stderr per test, so the watchdog's 'shutdown stalled' line never reaches the pty in the harness child (the real binary writes it to fd 2 - the lane's VM bench legs assert it there). The stalled-drain leg instead asserts the forced exit structurally: the forced restore's own alt-screen leave lands on top of the exit path's (a clean exit leaves it exactly once), the flush never reaches the transcript tail (one copy of the last user row, the startup viewport's), and the process dies with the guard's exit code inside the stall window. Harness needles use the user-message rows (assistant rows carry per-word SGR spans) and the post-exit drain reads the pty's kernel-held bytes before asserting. * fmt: the slow-drain e2e needles and the watchdog's progress read * clippy: doc backticks + checked Duration subtraction in the guard tests; the e2e's needle check takes the direct is_none --------- Co-authored-by: perf-slowdrain-exitguard-fast <lane@hillclimb.local> * perf(pa-core): consolidate settings-lock reads - 32 lock cycles per first turn to 2 (#2941) * pa-ai/pa-core/pa-cli/pa-tui: grok-4.7 on every serving surface (TS #2505) + Claude Code 2.1.281 + Anthropic subscription ban-risk warning (TS #2645) + one owner for the Prime team header, retry failed !command credentials (TS #2497) (#2755) 7373eb471670merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * test(pa-cli): the interactive_daemon_e2e wedge root-kill - PDEATHSIG + orphan sweep + the 300s headless wall (#2942) dbed1170fa2bmerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-tui/pa-cli/pa-daemon: session opens wait through a daemon update restart (TS #2391) + the failed-restart hint (TS #2515) (#2763) e7a84e749089merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * perf(pa-daemon): the all-idle compaction fires like TS and rides the TS compact sync class - journals bounded (#2944) * perf(pa-daemon): settle-tail compact consolidation - the all-idle compaction fires like TS and rides the TS compact sync class The worker recovery journal's all-idle gate ran BEFORE the record insert, so a single-session journal's own busy admission record blocked every settle's compaction: the compact never fired on the dominant shape and the journal grew append-only for the session's lifetime (TS computes the gate POST-insert and compacts at every changed-idle record). The gate now matches TS, bounding the file. Where the compact fires, its temp sync_all was a sync class TS's compact does not pay (TS worker-recovery-journal: writeFileSync + renameSync, no fsync; the command journal's writeFileAtomicSync counterpart does carry fsync). The Finalize seam now encodes the sync class per owner: RetryBusy keeps its fsync (command journal), Synced keeps the Rust-native terminal-compaction journal's belt, and Bare is the TS worker shape - temp write + rename, no fsync. Durability is owned by the append path (the fresh-write class is untouched): the compacted form holds only records the append path already made durable, so a lost compact falls back to the append-only history, which replays identically. * test-only rustfmt of the new test call site (the gate's one fmt finding) * runtime/kernel: vendored-runtime hardening + kernel stderr owner-only (TS #2372/#2423/#2500/#2471/#2478/#2425 parity) (#2744) ea5abd1bbe1bmerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-tui: session_ui.rs split 11/14 - the prompt submit pipeline moves out of src/session_ui.rs (#2943) 3bafbc007b74merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * perf(pa-tui): 8-byte packed span records with per-pack style table - scroll retention -7.5MB, byte-identical output (#2939) * perf(pa-tui): denser packed span records - style table + derived offsets (8B/span), byte-exact range expansion * test(pa-tui): rustfmt the exhaustive row-pack range oracle * fix(pa-tui): clippy - if-let style dedup + drop redundant test clones * pa-tui: fix the submit-outlived-by-switch idle-gate race - the turn-end watermark restarts with the mounted stream (#2945) c661290b1b77merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-daemon: hold spawn-name reservations until admission is durable; collect returns cancelled envelopes for just-deleted targets (TS #2396 + #2388 F4) (#2757) 18aa772bd3b2merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-ai/pa-core/pa-daemon: codex stale-chain retry after metadata (TS #2374) + safety failures permanent (TS #2472) + quota park until reset with auto-resume (TS #2375) (#2761) dc9892ffbc1emerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * test(pa-tui): the headless settle bound names its stuck member in 60s - defense-in-depth inside the wedge wall (#2949) The interactive_daemon_e2e exit-gate wedge family is root-killed upstream (#2945: the turn-end watermark restarts with the mounted stream) and the harness carries the 300s wall (#2942). This closes the remaining gap: the headless settle was the run loop's only unbounded wait on the product side — a settle member that never drains parked the run forever with no failure name (TS exits the process at shutdown and lets in-flight work dangle, so the settle has no TS counterpart). The gate's twelve settle members are now snapshotted (HeadlessSettle: settled() is the old gate exactly; blockers() names them), and after the plan completes a stuck member fails the run within HEADLESS_SETTLE_TIMEOUT_MS (60s) with the member named — e.g. 'a turn still active' — instead of waiting out the harness's 300s wall with a generic timeout. Green settles are milliseconds after HeadlessDone (the suite's green wall is ~15s; the last submit's own ack bound is 10s), and terminal runs never arm the bound (HeadlessDone exists only on the headless harness; a live terminal ends the run on exit_requested + the exit guard). Proven end-to-end by the lane's matrix: the wedge converted to a 98.4s attributable red naming the latched member (the bound-only diagnostic arm), and the full candidate stayed clean at 30/30 interleaved trials vs 3/30 wedges at the lane parent (record 20260927-085200-interaction-exit-gate-hang-remediation, bench hillclimb). * perf(pa-daemon/rpc): warm the model registry at RPC session boot - first get_available_models 1170.6ms to 58.9ms (#2953) TS session boot resolves the initial model through refreshAvailableModels (model-resolver.ts), which also fetches the live Prime Inference catalog in the background and caches it on disk; the daemon worker fires the same fire-and-forget refresh from its create path (worker/create.rs). The RPC mode hosts the session in-process with no create command, so nothing warmed the caches: an integration's FIRST get_available_models call paid the whole awaited refresh chain on its response path (measured 812-1296ms on the bench VM; the 15s fetch-timeout worst case on a degraded network) while the same command on the daemon and ACP surfaces answers from the validated snapshot. Mirror the daemon worker boot spawn: the caches warm during the session's first turn, and the first call serves the same snapshot. Write behavior is unchanged: the same cache files, the same write-on-fetch-success conditions, the same cadence (hour-gated catalog refresh, 5-min private-authorization TTL), only started at boot.

The TS product holds its own lock across the same await (refreshOAuthTokenWithLock -> withLockAsync), but its single-threaded runtime never blocks other work on it; this engine is threaded, so the port narrows the lock scope instead: load-then-lock. The document loads through the consolidated read arm, the token fetch runs outside every lock behind a per-provider single-flight gate (the in-process serialization TS gets from its single-threaded runtime, with the expiry re-checked under the gate so a second caller never spends a single-use refresh token after the first flight landed), and the write re-enters the same locked read-modify-write protocol - now held only for the re-read, insert, and atomic write, and skipping the write entirely when a peer refreshed while the fetch ran.

The stop records a pending-stop gate (TS pendingStop) that the next start_kernel_impl awaits before reading the snapshot back, so a follow-up turn's fresh boot revives the flushed namespace instead of racing the flush; a completed stop awaits instantly and each stop supersedes the previous (a clonable watch receiver: multiple revival waiters gate on it). - The session engine gains stop_kernel_snapshot (the TS stopKernel({snapshot:true}) seam beside dispose_kernel), and the SessionEngine trait gains release_settled_child_kernel (default no-op): the AgentSessionEngine arm evaluates the canPassivateSettledSession gates engine-side - no unsettled descendants (has_unsettled_rlm_work), no registered cron/heartbeat jobs (a worker-wired probe over the shared cron store) - then fires the per-build release probe (a weak provisioner reference, the background-bash-probe adoption pattern, cleared on retire/close). - The turn runner's park arm fires it best-effort when the worker core proves the parent-owned, unattached, unqueued idle state (rlm_depth>0, no attached clients, not compacting, no lane work - the park arm's own construction). The divergence the port discloses: rust children are worker processes (the parent has no in-process reach and the wire is frozen), so the release triggers at the child's own idle park instead of the TS parent's run-settle hook - the same revivability semantics (the next kernel use boots fresh from the flushed snapshot), and the roster/collect surfaces are untouched by design. Tests: the provisioner stop flushes the snapshot and the next ensure revives the namespace (live-kernel, ambient-venv-gated); the park arm's policy matrix (a parent-owned child releases, a root/attached/compacting session stays resident); the engine gates (a registered-jobs probe defers the release, the probe fires otherwise). * test(pa-daemon): the park-arm release test waits on observable readiness (the review advisories) Two BUGBOT test advisories on the first review: the park-arm test's bounded poll used fixed sleeps (a retry-to-green readiness wrapper). The recording engine now notifies on every release fire, so the test waits for the observable readiness - the notification is the pass condition, the bounded timeout is only the failure bound for the positive arm and the absence bound for the gated arms (no fixed sleep ever makes a pass). The commit also lands the VM's cargo fmt output on the touched files (the first commit's hand-written formatting failed the review's fmt pre-flight: the lane builds on the VM only, and the formatted sources must sync back before every commit). * perf(pa-core): provider auth answers once per provider - the #2479 memoization ports, per-model probe -66% (#2973) * perf(pa-core): provider auth answers once per provider and the private PI authorization cache parses once per file identity (TS #2479) The rust port of the four unclaimed mechanisms of the stale perf PR #2479 (the supersession analysis: the rest of that PR's premise landed via #2932's storage read-cache): - get_available's per-model has_configured_auth becomes a per-provider memo: the catalog walks hundreds of models over a few dozen providers and each probe rebuilds the provider's auth-source candidates, while a same-registry probe is stable by construction (&self, no mutation between models). TS getAvailable's authByProvider map. - get_rlm_searchable_models' per-model get_auth_status becomes the same per-provider memo (TS _authenticatedRlmModels' selectableByProvider). - read_private_prime_authorization_cache serves from a process-wide stat-identity snapshot (dev/ino/mtime_ns/len, the TS CatalogFileIdentity) while the file is unchanged; the port builds a fresh registry per resolution touchpoint (the TS session kept one long-lived registry), so the parse would otherwise re-run on every resolution. Only a successful parse bracketed by one identity is pinned, a failed read unpins (retries), and the write path's atomic rename supersedes (new identity). - AuthStorage memoizes auth-source candidates keyed by the hashed material itself (TS authCandidateMemos): reuse skips only the SHA-256 work, env values are deliberately re-read on every call, command values resolve before the memo, and stale checks run against the memoized candidate (candidates are immutable). Tests: the per-provider status memo gates one stale provider across all its models while a second authed provider keeps its models; the private-cache snapshot pins stable parses, re-parses rewrites, and never pins a failed read or resurrects a deleted file; the candidate memos supersede exactly when the hashed material changes (a stale marking from an old value never gates a changed one). * test(pa-core): the stale-provider memo test asserts the tip's stale-aware has_auth The memo regression test claimed a stale-marked provider's models stay in get_available ("stale is only the searchable-set's gate") - but AuthStorage::has_auth is stale-aware at the tip (available_candidate skips candidates matching a marked stale token), so get_available gates the stale provider too, and the tip's get_rlm_searchable_models gates it twice over. The memo preserves exactly those semantics; assert them: the stale provider is gated across all its models from BOTH sets, and a second authed provider keeps its models. Discovered by the full-suite fleet gate (gate_1790546015_945232) - the lane's local legs had not run the test suite; the three other gate reds (kernel_restore_guards x2, tui_prime_login_escape) are SOLO-GREEN on the exact head content (co-scheduling class, the standing family from gate_1790531716). * test(pa-core): behavior-focused wording in the candidate-memo test comments (the review advisory) The BUGBOT history-narration advisory asked for comments that state the current behavior rather than the sequence of edits: the env-change arm now says what the memo key does (a changed value changes the key, so the rebuilt candidate's value fingerprint differs from the stale token's) and the return arm says the marked material's candidate re-serves when its value returns. * pa-cli/docs: the update fetch source flips to the official domain at the rust-to-main merge (#2984) 309dd96b1f96merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-tui: agents_view.rs split stages 1-2 -

linear line framing (TS #2781 twin) (#3042) * test(pa-core): the multi-MiB protocol-line timing tests for the kernel reader and the extension LineDecoder (TS #2781 twin) A 4 MiB decoder line fed in 1 KiB chunks and a 31 MiB blank kernel line read through the 64 KiB pipe reader must complete under the computed bounds: while every chunk rescans the buffered prefix, they scan >= 8.6 GB and >= 8 GB and overrun them. The blank line never reaches parse_event, so the bound separates pure scanning from the quadratic rescan. Failing runs report their real duration in the assertion message. * perf(pa-core): the kernel protocol reader and the extension LineDecoder scan each byte once - linear line framing (TS #2781 twin) Both readers keep only the newline-free tail of earlier chunks, so the newline scan resumes at the old buffer length instead of restarting at zero: while one line accumulates, every chunk rescanned bytes already known to hold no newline. The decoder also consumes lines by offset and drains once per feed instead of one O(remaining) drain per line. Measured (8-core sandbox, prebuilt debug test binaries, medians of 3): a 4 MiB decoder line in 1 KiB feeds 14.27s -> 0.014s (~1000x); a 31 MiB blank kernel line 13.85s -> 0.65s (the ~13.2s quadratic rescan eliminated; the remainder is the one-pass scan plus the UTF-8 and trim checks the blank line still pays). Frame handling is byte-identical: same oversize checks and order, CR and blank-line rules, invalid-UTF-8 endings, and post-error buffers. * perf(pa-daemon): mint session entry ids against the by_id index instead of rebuilding an id map per append (#3053) append_entry and persist_entry_at rebuilt a HashMap of every entry id on each call just to check the new id for collisions. The store's by_id index already holds the same ids, so check against it: appends drop from O(n) to O(1).

The CLI now sends them in the daemon create config under the TS field names, the supervisor keeps them in the stored create command, and the worker feeds them into every session build (autonomous starts enabled with its limits). * pa-tui: the @ fuzzy file search - fd's ignore-crate walk off the UI thread (#3097) `@` tokens route to a background walk with fd's semantics (the ignore crate: --type f/d, --follow, --hidden, --exclude .git, the 100-result cap, smart-case regex on the name - the whole path for slash queries, the scoped @dir/ form, quoted values); TS scoreEntry sorts and truncates the menu, and the apply adds the TS @ branch's trailing space for files. The editor parks the request at its idle tick, drops a stale search on the next one (cancelling the walk), and a new request aborts the in-flight one. * perf(pa-daemon): the resume create folds the saved context once - the model restore's second windowed open and its duplicate fold are gone (-62ms / -98% of the create-path restore class at the 22.9MB image-heavy fixture) (#3127) f5384e379cbamerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * perf(tui): the attached idle wake cut - the reader parks edge-driven, the quiet tick arms only on pending work (#3126) 73dae6dd89d8merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * fix(pa-daemon): saved sessions keep their parent link, and the family view checks depth so forks are not children (#3041) * pa-daemon: saved rows publish the header binding and the family classifiers apply its depth (TS summaryForInactiveSession + selectAgentFamily) `saved_session_summary` now publishes `rlmDepth` always and `parentSessionPath` only when one is recorded, restoring the TS `summaryForInactiveSession` row: a session a user created under a parent (feature 1's top-level file binding) keeps its family edge in `agent_observe`/`agent_message` once its worker is gone, exactly like a resident one. Publishing the binding alone would regress: a fork carries its source's `parentSessionPath` at its source's own depth, and the depth-less file arms of `row_is_child`/`row_is_sibling` would read it as a child (live forks already are; saved ones would become one). The file arms now apply TS `selectAgentFamily`'s depth rule - a child sits exactly one level down, a sibling at the same depth - read from `FamilyIdentity::rlm_depth` (from the session summary) and the row's `rlmDepth` (TS `agent.rlmDepth ?? 0`). The spawn-id arms stay depth-free: only spawned children carry them, and a spawn always sits one level below its parent. Operator context: the "agents and users are equal collaborators" ruling (snimu 2026-09-28), same precedent as the chrome.rs 2026-09-24 directive notes - daemon-side internals only, no new public surface, no pa-types change. * pa-daemon: a depth-0 binding is no parent edge - the family reads route through one parent_binding accessor (TS familyCatalogEntry) Review fix for 3e14b7e51: the depth rule alone broke the common `/fork` case. A fork of a root carries its source's `parentSessionPath` at depth 0, and TS never treats a depth-0 binding as a parent edge (`familyCatalogEntry` keeps `parentSessionPath` only when `depth > 0`) - a root fork is a plain root and a Sibling of its source. The first commit's classifiers instead read the raw field everywhere, so a saved root fork vanished from its source's family and a live one went from Child to absent. One accessor now states the rule once and every family read of `parentSessionPath` routes through it: `from_summary` (a root fork's identity is top-level, its source is a Sibling, never its Parent), `row_is_child`'s file arm, `row_is_sibling`'s top-level arm (a root fork row is a root too) and its file arm. The wire keeps the raw field (TS also publishes it in `summaryForInactiveSession` and strips it only when building the family catalog), so saved rows and peers are untouched; the `parentSessionId` half of the TS guard is not needed (spawn ids only exist on subagent summaries, always depth >= 1). Tests: the family test is renamed and now expects the root fork as Sibling; a new part (iii) builds the fork's identity through `from_summary` - without read 1 it labels its source Parent and drops the other roots. The two moved-parent fixtures gain the `rlmDepth: 1` every real worker summary publishes (the identity is a depth-1 child). The whole-tuple asserts and the `row_depth` reuse in `from_summary` fold in the review nits. * feat(pa-tui): the activity dock renders in every session, all-zero included (#3036) The bottom activity dock was mounted only while some count existed (subagent history, heartbeats, bash history, or a live goal), so an idle session rendered nothing below the tray. The operator's 2026-09-28 directive: the dock renders in every session — the muted rule plus ` ◆ 0 subagents · ◷ 0 heartbeats · ▸ 0 shells` — and its Subagents group opens the scoped agents view even with no children, which shows the view's existing `No sessions yet.` empty state (TS `SubagentSummaryLine` renders nothing at zero; sanctioned divergence, the same precedent as the chrome.rs operator-directive notes). - delete the visibility premise: `ActivityDock::visible()` and the `subagents_total`/`bash_total` fields (their only consumer was the gate); `render_activity_dock` returns `Vec<Line>` and drops the `width == 0` early return (the truncator already yields an empty row at width 0 — keeping the guard would be an impossible-state defense) - `update_subagent_summary` always mounts the dock; a focused selection only steps when its group leaves the row (only the goal group can) - `focus_activity_dock` (alt+a and every dock panel's close) always takes focus; the duplicate step-into-groups copy is gone (`update_subagent_summary` owns that step) - the scope-back dock-focus restore is assigned directly after the attach (the attach's rebind reset clears focus): the `pending_dock_focus_restore` one-shot deferral existed only so the restore could check `visible()` once the roster had seeded - the PromptDown gate stays (TS `isSelectable()` parity — the prompt's Down keeps input-history recall in zero sessions), and `DockFold` keeps its machinery with counts-rationale comments Tests: the all-zero headless e2e (the dock row renders, alt+a + Enter opens the scoped empty view, which carries the exact AgentsViewScope) fails without the change; the childless-scope unit test pins the newly reachable empty view's keys (search, Enter no-op, escape back, ctrl+d, ctrl+n dispatch); the pinned mouse-selection geometry moves two rows up (25:66 -> 23:66) because the dock always renders. Visible behavior note (the operator's 2026-09-26 panel-exit ruling now applies in zero sessions): closing the heartbeats view, the bash view, or the goal panel restores focus to the panel's own dock item instead of the editor; typing still releases the focus into the editor path. * revert: the auto-backgrounding guards (PR #3076) - not yet (#3129) 7ebcf2c7f409merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * clippy: pa-tui is pedantic-clean (#3134) b4ff5a053977merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * perf(pa-agent/pa-daemon): stop copying the whole streamed message on every delta (#3045) * perf(pa-agent/pa-daemon): share streaming partials via Arc and convert to wire form at coalescer flush * pa-daemon/pa-agent: review fixes for the streaming-snapshot change * perf(pa-tui): cache settled markdown blocks like TS and reuse the cache for row counts (#3060) * pa-tui: cache settled markdown blocks like TS and reuse the cache for row counts * pa-tui: tighten the markdown cache comments * pa-tui: accent every recognized slash command in the editor (#3080) * chore: remove the ci/ workflow staging dir - the promotion-era holdover (the live set is .github/workflows/) (#3133) 6a6d22e35984merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-tui: a mouse click expands only the clicked card (#3043) * fix(pa-tui): a mouse click expands only the clicked card * fix(pa-tui): the layout handoff skips clicked cards - the re-entry renders them at the level A clicked card's layout slot holds its flipped rows, but the toggles live in the exiting view and the re-entered chat starts with none. The agents-view round trip served those rows anyway: the card rendered expanded while its row count said collapsed, and the next click looked like it did nothing. stash_layout_handoff now skips the entries in toggled_cards, so they re-render at the conversation level on re-entry, like TS mounting fresh components. * feat(pa-daemon): the whole-worker idle passivation - TS idleEvictionMinutes gains its consumer (the settled-child whole-worker stop, the passive-row survival, the wake-and-revive) (#3104) 7e42d9718928merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * fix(pa-ai): the windows-latest pair - the callback port-bind + the bedrock h2/http1 answer (#3137) 43a9f20004ebmerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * fix(pa-ai): the review pass on the windows pair - the readiness event replaces the fixed sleep (#3141) 82abcc6e48e9merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * pa-tui/pa-cli: the kitty probe's verdict-time contract locked as e2e oracles (the DA1 early conclusion timed + the deadline's late-kitty role documented) (#3138) 760f2e275134merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge);

THE CONTRACT (the abort-idle-race lane's rate-harness precedents, made deterministic): - THE DIRECT-DRIVE FIRE: the raced window lives inside `maybe_request_idle_passivation` - the engine gate's await, between the fresh-snapshot fence and the post-await revalidation. The harness drives that path directly, with the fixture's idle clock already two minutes past the park stamp (the exact `now_ms()`-elapsed shape the park arm produces, so the fresh-clock gate passes deterministically; no test waits a real threshold). The park->window->timer leg is wall-clock-bound by design (the park re-stamps `last_activity_ms` from `SystemTime` and the fire re-checks the same wall clock - no in-process clock fake can carry the fire past its own gate, and `idleEvictionMinutes: 0` is not a zero threshold) and stays pinned at rest by the park family's window battery; the product's own e2e drives the request directly under the same discipline. - PROBE-TRUE-AT-THE-SEAM: the GateHoldEngine parks the fire at `can_passivate_settled_session` - the exact await the post-await revalidation covers - and counts the entries, so the racing event never lands blind. - THE JOIN BARRIER: the settle is the fire task's own join - the raced continuation runs to completion before any assertion; no test sleeps. - THE TRANSCRIPT ASSERTION: a recording supervisor-side socket OBSERVES the ask as the exact `worker_idle_passivation` command (the served-path oracle, the `window_serves` pattern). - THE SERVED-PATH PAIRING: every cancel arm shares the positive arm's fixture, so a broken link fails the positive arm first. THE PINS: the post-await revalidation set (a client attaching, lane work parking, a manual compaction starting, an input suspension engaging, a user bash admitted, a shutdown starting - each cancels the stop and keeps the racing work intact), the departure release chain (the attached hold closes the window; the release re-arms it; the fire from the departed state reaches the supervisor), the shutdown's bash-admission pair (a bash dispatched inside the stop is refused "Session is shutting down"; a bash admitted before the gate is aborted and settles cancelled), and the attach/close token lifecycle in both orders (the close beating the late registration, the registration beating the close, the non-final detach's re-attach, the shared-id reconnect, the 8192 overflow cap). THE TWO RESIDUAL FIXES the harness found: - the post-await shutdown arm: the round-9 "uniform predicate set" claim did not hold at the post-await site - a graceful shutdown starting during the engine gate's await left the stop ask racing the worker's own exit. TS's fresh-snapshot fence checks `shuttingDown` at the same point (daemon-mode.ts `passivateSession`); the arm ships with the harness. - the attach's core retain rides the registration verdict: the round-8 belt closed the dead token's REGISTRY entry but the ungated core push still leaked the id in `attached_client_ids` with no registry entry left to release it - the idle passivation's unattached gate would close forever on one closed-then-late attach. A routed attach without a connection token keeps its retain (its release rides the routed detach). * fix(pa-cli): the ACP config fixture redirect resolves on windows - the registry fallback order (#3162) 462c9fa8934dmerge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * fix(pa-daemon): the interleave harness's compile + fmt pass (the sibling-park fixture import, the buf-read trait, the join handle's take) + the doc tick * ci/install: the R2 publish phase - the release ships to the bucket, the user path never touches GitHub (#3154) 36eecc783ae2merge bar v23: mandatory CI green on the exact head + zero unresolved bot threads + head unmoved (verified by fleet_pipeline.fleet_merge). * fix(pa-daemon): the interleave harness's doc tick + the settle signature's fmt pass * chore: the workspace version reads 0.9.8 - the TS shipped 0.9.8, the first beta must be v0.9.8-beta.1 not a regression * docs: the installer header states the R2 channel - the stale workflow-artifact source line retired * perf(pa-tui): the ! bash card keeps only the output tail it renders - same rows, bounded memory (#3038) The card stored every output line for the whole session. Every render joined all of them and split the result again. Streaming a large command made this quadratic. The card now keeps only the last 50 KiB + 1 byte of output, which is all truncate_tail needs to return the same visible tail and truncation flag. 30 MiB stream (sandbox, release): 3.7s -> 28ms; 100 repaints 652ms -> 2.1ms; peak RSS 131 MiB -> 7.7 MiB. * fix(pa-daemon): raise the open-file soft limit to the hard limit at daemon start (#3150) macOS starts every process with a soft RLIMIT_NOFILE of 256. The daemon holds about two unix sockets per worker, so it runs out of descriptors near 115 workers and then fails accepts and worker spawns. Node raises the soft limit at startup, which is why the TS daemon never hit this. The supervisor now raises the soft limit to the hard limit before it binds its socket (capped at kern.maxfilesperproc on macOS, which refuses RLIM_INFINITY) and logs the result. Workers and kernels inherit it. * pa-tui: one guttered layout for expandable chat rows (TS #2779; Rust gutter/refinement conventions kept) (#3049) * pa-tui: one guttered layout for expandable chat rows (TS #2779; Rust gutter/refinement conventions kept) Port the layout from TS #2779 to the Rust TUI. Shell completions, injected prompts, the skill card, the generic custom panel, and the compaction summary now render their expanded bodies the same way: a dim gutter on the first non-blank body row, a four-column indent on the rest, every row clipped to the width. - Skill card and generic custom panel lose their customMessageBg boxes. - The skill body no longer repeats the skill name. - Injected-prompt headers drop the invisible expand-hint space. - Compaction metadata moves onto the expanded header row. - Markdown bodies share one new helper pair in branch.rs. Kept on purpose (operator decision, 2026-09-28): the gutter sits on the first non-blank row, and the refinement outcome keeps its layout. * pa-tui: update the expanded compaction header assertion in the view test * test: proptest pilot - property tests replace the framer, view-geometry, and tool-card example tests (#3099) * test(pa-daemon): the interleave harness on main's engine gate, plus the review fixes - GateHoldEngine implements main's renamed can_passivate_worker (the old name no longer exists after #3206; the new default is false). - the fixture no longer pins rlm_depth 1 (roots reach the fire since #3209). - the released-token set clears BEFORE the insert, so the overflowing release still rejects its own late registration; the cap test pins it. - the departure test (no real release, park.rs covers it) is removed. - the shutdown admission test and the turn.rs comment claim only what holds (the gate, not its order vs the abort; stricter than TS's shuttingDown check). - the gate release uses notify_one so a not-yet-polled waiter cannot miss it. * chore: retrigger CI (shard 5 flake: tool_results stats fold count, unrelated to this PR) * chore: retrigger CI (e2e timing flakes: stats fold count, stop tombstone wait — unrelated classes, 3 different single-shard flakes incl. on main itself) * chore: retrigger CI (4th distinct single-shard e2e flake across runs incl. on main itself — infra flake window, tree unchanged) --------- Co-authored-by: perf-catalog-second-parse-fast <hillclimb@local> Co-authored-by: perf-tui-memory-fast <perf-tui-memory-fast@hillclimb.local> Co-authored-by: perf-daemon-rss-fast <hillclimb@prime-intellect.local> Co-authored-by: perf-model-resolve-cache-fast <hillclimb@prime-intellect.ai> Co-authored-by: perf-tui-scroll-retain-fast <perf-tui-scroll-retain-fast@hillclimb.local> Co-authored-by: wc <wc@fleet.local> Co-authored-by: perf-slowdrain-exitguard-fast <lane@hillclimb.local> Co-authored-by: perf-rpc-models-persist <lane@hillclimb> Co-authored-by: perf-launch-open-fast <hillclimb@primeintellect.ai> Co-authored-by: Sebastian Müller <sebastian@primeintellect.ai>
