Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Owner, 2026-10-13: "we need to implement this osc for our terminals along with osc 52 (anything else we are missing?)" — pointing at OSC 7501, the Program Status Protocol (spec: https://mitchellh.com/writing/program-status-osc7501).
OSC 7501 lets a program (AI agents first: Codex, Claude Code, others) tell the terminal its state deterministically:
ESC ] 7501 ; key=value:key=value STwith states idle / working / blocked (kind=permission|question|auth) / done / error / clear, optionalapp, base64msg,idfor one record per run (subtasks), and a queryESC ] 7501 ; ? STthat the terminal answers with the same body (programs treat no answer as unsupported).Why it matters more for infraternal than for a local terminal: our sessions live on hosts and keep running when nobody is attached. The shim can keep each session's status and the server can surface it everywhere: a badge on the window's machine pill, the Inbox and push when an agent is blocked on a permission or a question, "done" when a long run finishes — across machines.
Scope of the backend work (UI comes after a mockup the owner approves):
Started terminal-osc on branch
terminal-osc, base1f637cbb2b3948a301fa63f1fa8d9dbe42382b4e. Read #209 (no prior comments) and #206 (all 2 comments); #209 names no parent issue. First step: inventory existing shim/renderer/replay/query routing. Spec fetched: article links to normative revision 0.4 (2026-10-10), which includes title, progress, hierarchical clearing/app inheritance, and fixed capability-only query replies; queries do not return stored records. Backend only; no deploy. Push only this task branch as explicitly instructed in the brief.Inventory at base
1f637cbb(before implementation). “Replay” distinguishes retained raw ring bytes from a generated snapshot. No OSC has structured server status today; raw PTY output reaches the server/viewers.Evidence: scripts/build-vt pins a887df42; upstream src/terminal/{osc.zig,stream.zig,c/terminal.zig} separates effects from state; shim terminal_native.rs does not install effect callbacks. crates/infraternal-shim/native/snapshot.zig:22–26,126,527–563,813–823. apps/tracer/vendor/ghostty-web/README.md records the different browser VT pin (5714ed07), so #206’s “same VT” does not mean identical revision. dist/ghostty-web.js:1442 (OSC8),3308–3341 (replies/title regex); apps/tracer/src/terminal.ts replay fences suppress historical replies but live viewers all emit onData. No UI changes planned.
OSC 52 security model proposed before code: explicit per-session write permission defaults false; reads (payload ?) never access a viewer clipboard and receive no data reply. Accept clipboard c / empty selection only; reject other selections, invalid base64/non-UTF8, and decoded payloads over 64 KiB (encoded ceiling 87384). No clipboard payload persistence, logging, or snapshot/replay effects. Deliver each live operation only to the authenticated writer that most recently accepted new typing, never all peers; duplicate input cannot select a viewer. On disconnect or permission revocation discard pending operations; do not forward to a replacement peer or retry. Browser OS clipboard permission still applies. A backend-only delivery event prepares the eventual viewer wiring; actual browser clipboard integration must be reported separately if absent.
OSC 7501 grammar: normative revision 0.4, https://www.superlogical.com/rex/docs/build/program-status (linked from the requested article). OSC := ESC ]; ST := BEL or ESC . reports pairs := pair (: pair); pair := key = value; key := [a-z]+; value := [A-Za-z0-9_.,+/=-] with surrounding whitespace stripped. Skip malformed pairs; ignore unknown keys; last valid duplicate wins. Required recognized state idle/working/blocked/done/error/clear. id := segment (/ segment)*, segment [A-Za-z0-9_.+-]{1,32}; absent root. Reports replace records completely; subtree clear and nearest-ancestor app inheritance. kind permission/question/auth only blocked; progress integer 0..100 only working/blocked; app segment grammar. msg/title standard padded or unpadded base64 UTF8, no U+0000..001F,007F..009F. Whole report discarded atomically if any hard limit/base64/text validation fails. Limits: sequence 4096; key16; msg2732 encoded/2048 decoded; title256/192; app32; id128 and8 levels; choose64 records (minimum supported), evict least recently updated. RIS clears all; DECSTR preserves; OSC133 A / attached-process exit remove working/blocked, retain done/error and idle. Query replies once from shim with fixed ESC ]7501;?:states=idle,working,done,blocked,error:kinds=permission,question,auth ESC , never untrusted record contents. State lives in surviving shim across daemon/server restarts (D128); a shim/host crash is not session survival. No periodic work (D81).
Additive shim contract proposal before implementation (#209): reserve cap bit5 PROGRAM_STATUS, metadata-only Attach selecting exactly bit5 (no writer, output cursor, input, resize or backpressure). New 0x22 ProgramStatusRequest (empty) and 0x23 ProgramStatus (bounded JSON records) allowed only after bit5 negotiation. Metadata link emits an initial full snapshot and coalesces later changes by revision, retaining no notification queue; reconnect obtains authoritative shim state even without output ring coverage. Old shim layouts/caps unchanged. Record ownership is the surviving shim, not a browser or snapshot painter. Status watcher on the daemon control lane is intended for detached-session server delivery.
Reserve cap bit6 CLIPBOARD_WRITE for negotiated data writers. New 0x24 ClipboardPermission (canonical bool byte, host-to-shim) and 0x25 ClipboardWrite (UTF8 text, shim-to-host, 64KiB maximum). Permission defaults false and output never changes it. Only the last newly accepted typist with a live negotiated ordinary peer can receive a live operation; no shared/shadow peer, historical output, snapshot, disconnected successor or broadcast delivery. This backend wire seam does not itself implement browser clipboard writes; server authenticated action/focus binding and eventual viewer adapter must be wired before claiming end-to-end clipboard functionality.
Hard storage bounds chosen: 64 records, maximum stored text per record 2048+192 bytes, app32/id128; 50 sessions <=7,680,000 field bytes plus Rust containers. OSC scanner live storage bounded to 87,392 bytes (lazy capacity <=131,072), so 50 hostile streams <=6,553,600 capacity bytes; normal ground text stores nothing. A fixed query reply is shim-owned PTY input, independent of viewer Ack offsets. No heartbeats, polling or idle timer. Benchmark evidence must use the perf VM per the later explicit owner rule; no timing measured on this build host will be claimed as performance evidence.
Remaining OSC recommendations (#209 / #206), based on the inventory:
Additional parser finding: existing terminal.rs unfinished-carry storage is bounded, but its std-enabled vte::Parser owns a separate dynamically growing OSC buffer. The new effects scanner is bounded; it does not by itself fix the existing VT engine/parser allocation paths. This needs measured defensive handling without breaking native VT fidelity; do not advertise total terminal memory as bounded solely from the new scanner caps.
Mockup for the program-status UI (branch
mockup-program-status, head9d5e1120). Preview:?mock=1&proto=clusters&program=1(still scene, one window per state) or&program=live(plays in over time); add&theme=ink|paper; then fly to Console. Test double only: nothing parses OSC 7501 yet.Zoomed out (blocked and error flag themselves):










Console, ink / paper (working x2 subtasks, done x3, blocked permission with tooltip, question, error):

Live mode, a short run ending (tick, no inbox entry):
Step 1 committed and pushed:
1d1f94b8(workspace base64/serde/serde_json reuse plus typed existing byte assertion). Exact staged tree passed cargo fmt --all --check and cargo clippy -p infraternal-shim --all-targets -- -D warnings. Dependency regression run: 77 passed, 0 failed, 13 ignored, 2 filtered (the two large native smoke corpora remain in the final full gate). No new library version. Inventory, security model, normative grammar, additive contract proposal and remaining-gap recommendations are above. Implementation remains in progress; no API/MCP or clipboard viewer functionality is claimed yet.Program-status mockup reviewed and published to the clusters preview (combined with the access r3 mockup) at
e9d1ac42:Test double only; nothing parses OSC 7501 yet (backend job
terminal-osc). Deferred brotli margin now 101 B.Step 2 committed and pushed:
2ed26fd8, bounded OSC 7501 record parser/store. Exact commit tree passed fmt and shim all-target clippy. All 4 record-store tests passed (replacement, app inheritance, subtree clear, 64-record eviction, lifetimes, malformed/oversized/base64/control validation). No heartbeat/timer, no screen-based status inference. Next: streaming effects, negotiated shim framing and pump integration; server/API/MCP wiring still pending.Concrete malformed-output allocation finding: the carry observer uses std-enabled vte::Parser, so its raw OSC payload Vec can grow even after terminal.rs pending carry reaches MAX_FRAME. Added a failing production-configuration test before the fix: carry_parser_uses_fixed_osc_storage_in_production failed with Parser<1> and Parser<1024> both size 432 (generic capacity ignored under std). Fix under validation selects the same pinned parser's fixed-buffer mode for production; comparison examples explicitly retain ansi/std behind bench-vt. The new effects scanner remains independently capped. This changes dependency features, not the chosen VT engine. Full native engine allocation behavior is a separate remaining bound to review.
Steps 3–5 committed and pushed:
e215bfa1streaming scanner (3 tests);18972b74additive codec (10 frame tests passed, legacy golden unchanged);bb2c82ccfixed-buffer carry observer (44 native terminal regression tests passed, 8 ignored, 49 filtered; two large smoke corpora retained for full gate). Every exact commit tree passed fmt and shim all-target clippy. Failing test for the observer allocation configuration is recorded above. Next: commit shim pump integration/reattach and one-viewer tests, fuzz target and additive contract. Server/plugin/API/MCP delivery, actual daemon/server restart fixtures, performance VM measurements and static size delta remain unfinished. No deployment or UI changes.Shim integration and measured optimization committed/pushed:
fa7e6701(89 regression tests passed, 13 ignored, 2 large smoke corpora retained for full gate);0c39a739skips ground-state text runs (9 targeted OSC/native/socket tests passed);da577c58fixes malformed-id root fallback after a failing test (state=done:id=!, invalid-UTF8 clear id). All passed fmt and shim all-target clippy.Perf VM
infraternal-perf-test, x86_64, 4 vCPU; shared lock held only for each short run. Paired five-run load 0.13/0.72/0.94 before, 0.34/0.75/0.94 after. Same static harness, 50 parser instances, 100 MiB total plain text: bytewise median 740.404 ms / 135.061 MiB/s; run-skip median 45.372 ms / 2204.008 MiB/s (16.3x). Maximum records: 64 per session, 2048-byte msg and 192-byte title; incremental RSS about 9.18 MB over 50 sessions (~183.6 KB/session). This is only OSC storage/scan cost, excluding native VT, ring, sockets and terminal latency. It is not evidence that end-to-end budgets pass.Paired receipt: osc-scale-paired.log. Initial exploratory receipts: bytewise, run-skip.
Workspace fuzz target compiles and passes target clippy (pre-existing dependency warnings in server's no-SSH feature combination). Actual fuzz execution, full head gate, static size delta, real daemon/server restart fixtures and server/plugin/API/MCP/permission-focus/viewer wiring remain unfinished. No UI or deployment; keep this issue open.
Milestone full gate at
b0f7b379found a feature-unification regression in the new configuration test: workspace dev-dependency vt100 re-enables vte/std, so Parser<1> and Parser<1024> both remained heap-backed (432 bytes). Production package builds without that dev feature still select the fixed buffer, but the configuration alone is insufficient if std is later unified. Stopped only this job's verify process tree by its recorded PID after the known test failure; static measurement is incomplete and no size delta is claimed from that interrupted run.Added an actual payload-bound test with vte/std explicitly enabled; it failed before the fix on a completed 32-KiB OSC. Fix under validation keeps the original bytes in bounded snapshot carry while withholding printable OSC payload from the completion observer after 1 KiB; cancellation/termination controls still reach the pinned parser. This avoids relying on dependency feature isolation and preserves native VT input unchanged. The final full gate will be rerun on the corrected head.
Found and tested an exit-delivery race in the new seam: session.rs unowned retirement checked only peers with output cursors. A metadata-only peer could have final done/error records queued by Peer::status, then be closed before that frame flushed. Added a failing test final_status_must_drain_before_unowned_retirement with a real Unix socket and native terminal before the fix.
Proposed clarification of the additive #209 contract: final current metadata revision participates in the existing exit-delivery fence, including when an older revision was queued. Metadata links still do not own sessions, backpressure the PTY, add an idle timer, or extend the original maximum 600-second child-exit deadline. The correction is under validation. Server/API/MCP and authenticated clipboard permission/focus adapters remain absent; this is still a backend foundation, not completed end-to-end support.

Continuation r2 started on
terminal-osc, base/headedc9356412a2fb6800b5f3d7ab694a1f7688f027. Read all #209/#206 comments; neither names a parent. Resume the implemented shim seam; no rebase, deploy or UI. Next: removable D198 terminal metadata plugin, detached status delivery and D16 session actions, authenticated OSC52 permission/typing binding and browser consumption, real restart fixtures. Normative grammar/security remain as proposed above.scripts/verify iterateis absent at this head; use targeted per-commit gates and full fast at milestone/head. Inherited D243 static ceiling failures remain recorded; ceilings will not be raised.Additive D198/D16 proposal before code: generic node-plugin runtime hook receives authenticated live session identities through a coalesced watch and emits content-free invalidations on the existing plugin-event path. Plugin owns all metadata sockets/tasks and drops them when disabled. No output reader/backpressure or timer. New removable terminal-status plugin reads authoritative shim records; bounded paginated control reads fit the existing 8KiB action limit (full 64-record snapshots can exceed it). Server actions and subscriptions validate session ownership from terminal_sessions before reading any program-controlled text. Status cache is reconstructible from surviving shims across server restart, not a second authoritative database. OSC52 remains a live targeted stream event; permission is authenticated/session-scoped, never enabled by output. No permission is inferred from status kind=permission.
Steps committed/pushed:
b4de2474generic cancellable node-runtime API (23 tests);6d06ce96host worker/census integration (55 tests passed, 7 measurement tests ignored);359b1f49decoded record validation (5 tests). Each passed touched-crate all-target clippy and fmt. New plugin validation caught a too-small snapshot cap before commit: 64 valid records with JSON-escaped maximum messages/titles encode to 292855 bytes; the 256KiB proposed consumer cap refused them. A failing maximum-snapshot test precedes correction to bounded 384KiB; individual node pages remain below the existing 8KiB action limit. Integration remains in progress, no completion/deploy/UI claim.Progress: real-binary daemon/shim integrations now pass for status across detach, daemon restart, reattach and component disable/reconstruct, and for OSC52 with two writers: default deny, explicit allow, exactly stream 3 (last new typist) receives the write, reads and non-clipboard selections are refused, revocation denies subsequent writes. Seven plugin tests pass, including foreign-account no-node-call, stable revisions, maximum escaping, runtime reconstruction and stored clipboard consent at authenticated commit/delivery. Rust touched-crate clippy passes; browser clipboard consumption test is running. A first full server unit run passed 238 rows and failed the existing discovery-first-provider assumption after status was prepended; composition now appends the new plugin to preserve established ordering, targeted retest running. These are functional build-host tests, not performance evidence. Remaining: commit integration slices, real browser receipt, full head fast/static size delta, and review limitations including concrete MCP adapter availability. No deploy or new UI.
Milestone full fast completed: fmt/native fmt/compile-out/clippy/deny passed; Rust tests failed only two credit fixtures that assumed the next frame was a data Ack (new valid control invalidations interleaved). Fixed census classification/control draining; all 8 agent_review rows now pass. Static artifacts: x86_64 22549808 B, aarch64 19943240 B; ceilings unchanged (22204304 / 19638744). Compared with round-1 artifacts recorded above: +314208 / +277488 B; final exact baseline comparison and head gate still pending.
Additional runtime saturation finding: a pending-only coalescer still queued eight invalidations and could occupy action reply slots. New failing test expected one queued notice, observed eight.
ff60c3f4uses a delivery acknowledgement: one queued/in-flight notice plus one pending change; 57 node tests pass, 7 measurement rows ignored.Browser OS permission denial finding: the shared manual-copy helper retried rejected native writes through execCommand. Failing production browser test observed one legacy attempt after denial. The per-instance allowFallback option keeps manual-copy defaults while terminal automation refuses retry; focus, raw-OSC and denied-native cases now pass. Screenshot/receipts will be attached with final gate.
Interface limitation: contracts/plugin.md explicitly says MCP generation is not implemented in this checkout (existing paragraph around line 181). #209 supplies the single D16 action declaration and working WebSocket API read/subscription handlers, but no standalone MCP endpoint/device-session adapter is claimed. The shared MCP adapter must be supplied for literal end-to-end MCP delivery; no new authentication mechanism is chosen in this lane.
R2 measurement and item-4 recommendations at
b810000917.Dedicated perf VM (infraternal-perf-test, 4 vCPU / 7 GB), exclusive measurement lock; load averages 0.12 / 0.08 / 0.55. Real daemon/shims: 50 sessions × 64 records, each using maximum id/app/msg/title sizes. Node RSS grew 10,124 KiB (202.48 KiB/session), all shims grew 38,736 KiB (774.72 KiB/session). 100 private node page reads: median 0.701 ms, p99 1.064 ms, max 1.112 ms, injected RTT 0. These are retained-state deltas/private one-record reads, not whole-server/browser latency or total terminal-memory bounds. Readiness was outside the sample. Harness initially reused a stream before draining detach frames; the successful receipt fixes that boundary and avoids matching the echoed command marker.
Real PTY tests pass: status detach/daemon restart/reattach/disable-reconstruction; OSC 52 default deny, explicit enable, two writers with single last-typist delivery, refused reads/non-clipboard selections, revoke. Production browser functional test passes focused write, unfocused discard, raw/replayed OSC inertness and OS denial without legacy retry. Screenshot supplied for independent review; no visual quality verdict/new UI.
The original inventory remains correct for the other OSCs; this lane changes 7501 and 52 only. Updated recommendations:
7501 now has shim-authoritative retained records, metadata-only node reconstruction, authenticated session-owner WebSocket reads/subscription snapshots. 52 now has persisted per-session consent, bound-stream control, last-typist live delivery and focused client consumption; clipboard contents are never persisted/replayed. Standalone MCP delivery remains unimplemented because the shared generator/device-session adapter is absent (contracts/plugin.md); the D16 declaration alone is not an MCP endpoint. Whole server-process restart proof is still distinct from the passing real daemon restart plus server-source reconstruction tests.

Author review before handoff (
b8100009): checked declared action/topic bounds, legacy wire layouts, compile-out, role/worker lifetimes, ownership/authentication rechecks, replay/effect separation, clipboard default-deny/size limits, pagination consistency, module docs and licenses. Tests/receipts establish the covered cases, not all concurrency histories.Open recovery finding: crates/plugins/terminal-status/src/node.rs run() inserts observe() tasks with entry().or_insert_with; on socket failure observe clears the snapshot and exits, but the finished JoinHandle stays indexed. The run loop has only census/config watch wakeups, and unchanged sessions do not remove completed entries. Automatic retry after a transient metadata socket failure is therefore missing. This is a source-path finding; no runtime failing test or fix is claimed. Break-it review should add a failing reconnect test.
Completion limits: standalone MCP transport is absent (existing contracts/plugin.md paragraph), literal whole-server process restart integration is not covered (real daemon/shim restart and reconstructed Source are), static artifact budgets remain red. These are not green-gate waivers. The first head gate also hit remote_server failed_restart_endpoint HTTP startup timeout; exact targeted rerun passed. The final full rerun is still running; its actual verdict will be recorded without changing timeout or size ceilings. No deploy or issue close.

03ccd4ad: the final workspace feature combination exposed two Mesh refusal fixture failures (actual mesh unavailable, expected plugin unavailable). The status provider increases shared admission capacity; Mesh still rejects using its unchanged own bound and withdraws the subscription. Updated only the feature-dependent expected refusal text, retaining all queued-generation/unrelated-watch/withdrawal assertions.

Atomic module/adapter/test/docs commits are on the branch;
03ccd4adcorrects the final refusal fixture composition expectation. Functional production browser and real-PTY tests pass. Separate TypeScript fast checks (production build, transfer budget and protocol tests) pass; full fast stops at the Rust size failure.Not complete/merge-ready: no standalone MCP/device-session adapter (D16 declarations are not transport); full server-process restart integration is not proved (daemon/shim restart and Source reconstruction are); automatic metadata socket retry is missing as described above. Break-it review should cover these and disable/focus/query authority races. Other OSC recommendations and original inventory are posted above; #206 still owns global colour-query reply authority and synchronized paint scheduling.

Resume existing backend, first cargo-bloat attribution with identical static recipes, then cut growth and finish MCP/restart/reconnection. No deploy or UI; push only terminal-osc. scripts/verify iterate is absent at this head; targeted gates until full fast. Cargo.lock adds only the local terminal-status plugin, no third-party version changes. Size ceilings remain unchanged.Additive recovery/interface proposal before production edits (D16/D27/D63/D81/D128/D198): metadata observers will clear unavailable cache immediately and retry transient socket errors with bounded backoff only while disconnected; healthy observers keep no retry timer. Unsupported/malformed/foreign-peer handshakes stop rather than spinning. Disable, session withdrawal and runtime cancellation abort observers and any retry wait. Regression file crates/plugins/terminal-status/src/node_reconnect_tests.rs leaves census unchanged across a socket drop; failing run is queued, not yet claimed.
MCP: use standard newline-delimited stdio via a small Bun bridge and the already chosen WebSocket leg A as its documented custom upstream transport, not a new transport engine. The server adapter will use existing approved device API keys (terminal:connect scope), existing plugin read handlers and single action schemas; no browser-session privilege or clipboard control via that key. Generic session resource metadata will associate a read action/topic with a URI; read and subscribe are account-filtered through existing plugin workers. Bound requests, pending operations and subscriptions; recheck key authority before delivery and wake on revocation. Keep all status text untrusted, no new UI, no alternate status store. Full-server-process restart fixture will use isolated database/runtime directories and synthetic test capabilities only; it will exercise API reads/subscriptions and reattach against the same surviving shim. Size attribution remains in progress; no size or performance result claimed yet.

Diagnosis: no new third-party dependency/version/feature; OpenSSL, native unknown section, ring, rustls, regex tables unchanged. Diagnostic stripped binaries: base 22,235,208 B, head 22,551,176 B (+315,968); cargo-bloat enables diagnostic symbol settings, so these are not shipping artifacts (r2 shipping delta remains +320,320 B). Normalized nm text-symbol delta +260,925 B; whole .text section +263,232 B; remaining diagnostic file growth includes unwind/data/alignment. SQLx PoolInner.acquire has 3 base copies and 4 head copies; the new copy alone is 19,274 B. Other pooled-query/connection/drop/task instantiations grow too. Largest direct additions: status read 12,979 B, node runtime 11,781 B + observer 9,040 B, worker 7,988 B; record deserialize 5,813 B. Compiler closure indices were normalized to avoid mistaking renames for growth.
Next cut: retain SQL statements/authorization/storage behavior in the plugin, but use a generic boxed row-query bridge provided by the server, avoiding another crate-local instantiation of the SQLite pool runtime. Reuse existing serde JSON serialization directly and bound new task instantiations. No engine/dependency/profile/ceiling change.
Socket-loss regression failed before fixing production: 0 passed; 1 failed; 7 filtered; metadata socket loss must recover without a new census: Elapsed(()). This is a functional deadline, not a performance measurement.

SQL, owner/auth-at-commit and consent checks remain plugin-owned; statements are acknowledged only after completion. No new third-party dependency or profile/ceiling change. Shipping size after these cuts is not yet measured. Next: direct existing JSON encoding, device-key/native read adapter with stdio MCP bridge, and whole-server-process restart coverage. Full head gate remains required; no completion claim.First source cuts plus the read-only native device adapter produce a shipping x86_64 artifact of 22,476,016 B (+240,416 vs round-1 22,235,600; original r2 22,555,920). Still above the 16 KiB growth target and unchanged gate; no waiver claimed. Pool bridge/direct encoding/erased observer tasks remove duplicated machinery; no dependency or parser replacement.
Next measured size experiment: use size optimization for cold CLI/action metadata and the new terminal-status orchestration, consistent with the existing server package recipe. Keep the infraternal agent transport, protocol, shim/VT and cryptographic dependencies at their existing speed settings. Compare real 50-session node page reads, echo/flood and startup on the locked perf VM before accepting any profile change; reject a runtime-budget regression. All builds remain on the build host; no size ceiling increase.
The device-key revocation-wakeup regression failed before the fix (0 passed, 1 failed) and then passed; source auth/devices.rs now emits the existing committed-revocation notice when a key was actually deleted. MCP adapter unit tests: 3 passed (functional only, no build-host timing evidence). Real transport/server restart tests remain required.

Conservative existing-linker ICF=safe measured x86_64 at 22,458,928 B: -17,088 vs first source-cut artifact, still +223,328 vs round 1. Compiler speed profiles remain original. Next experiment emits LLVM address-significance metadata (--addrsig) so safe folding can recognize non-observable identical Rust sections. No unsafe/all folding, engine choice or runtime instruction optimization change. Pinned rustc exposes this LLVM option; upstream implementation: https://github.com/llvm/llvm-project/blob/main/lld/ELF/ICF.cpp and https://reviews.llvm.org/D48146 . Final functional gates/paired VM measurements remain required. The linker conservatively ignores invalid native archive address tables; no inference that these native sections are folded.
Completed real whole-server restart coverage on the 22,145,424-byte candidate: API read/subscription, stdio MCP tool/resource/subscription, foreign-account refusal, server SIGKILL/restart, surviving PTY reattach and retained records all pass. Fixture input now waits for replay-complete.

Gate finding: scripts/verify fast stops before Rust on a latency-proxy timing self-check measured on the shared build host (RTT=0: p50 45.17 ms / p99 783.47 ms). This is not performance evidence; owner instructions require all timing budgets on the perf VM. Proposed gate correction: fast retains real TCP byte-echo functional coverage with a bounded socket deadline, while scripts/verify latency retains the unchanged timing self-check/budgets for the perf VM. No production code or timing threshold changes. Add an explicit functional self-test switch, validate it locally and retain timed self-test validation on the locked VM.

Browser fixture now fails promptly on socket close rather than spending 100 read deadlines on a dead connection; no production timeout or authorization behavior was relaxed.Author review: checked account/scope isolation, revocation before work/delivery, bounded frames/records/stdout/subscriptions, parser/encoder reuse, no status-to-clipboard authority, no new dependencies or engines, plugin disable/observer cleanup/retry quiescence, module documentation and compile-out. #206 remains responsible for the other query and paint gaps. No new UI/deploy.

R3 implementation and verification finished on
terminal-osc, head83e820203143ce50077ed97ca3ebecc49969360a(pushed and remote SHA confirmed). Ready for independent break-it review; no deploy or UI. Issue remains open.Delivered actual authenticated native API + stdio MCP reads/resources/URI-only notifications from the existing plugin handlers; metadata socket retry after transient failure without healthy polling; whole-server SIGKILL/restart, same-PTY reattach and retained-record integration. Native restart and one-typing-viewer/write-only clipboard tests pass. Item-4 inventory/recommendations remain the R2 table above; #206 owns other query authority and synchronized-output paint gaps.
Both exact ceilings ratcheted down. No new native dependency or engine, no opt-level/LTO/unwind change. Attribution and rejected profile experiments are above. Conservative folding preserves observable identities; invalid native address tables are skipped, not unsafely folded.
Final
scripts/verify fastat this unchanged head:VERIFY_EXIT=0. All Rust rows PASS; MCP, production tracer/build/transfer and protocol checks PASS. Functional build-host checks used port 4299, RTT=0, one test thread and an owned CPUWeight=10000 scope; performance receipts use only the locked 4-vCPU VM. Full output is quoted verbatim below and attached.Measured limits: the maximum retained workload (50 sessions × 64 maximum-sized records) has full node RSS 18,060 KiB, above the 15 MiB target; no passing claim for that memory target or whole-server/browser latency. Existing echo/flood budgets pass. ARM key-memory runtime is not claimed on this x86 host. Author checklist and receipts are above.
Own temporary build targets, baseline archive, binaries, cancelled fixtures and perf-VM job directory removed; issue evidence retained. Stop here for break-it review.

Independent review started: branch review-terminal-osc, target
83e8202031; requested dev merge base8e7467c07c. #209 has no parent; reading #206 cross-reference as well. No push, deploy or perf VM use per review brief. Functional verification and failing tests only; performance claims cannot be independently remeasured under this restriction.Review step committed locally:
def0f072, OSC-R01 P2. Native successful Result with invalid JSON removes pending call before parsing; channel closes but request never settles, stopping sequential stdio handling. Real loopback wire testinvalid result JSON rejects the pending native call: 0 pass, 1 fail; result sent and channel closure asserted. Receipt: ~/.cache/codex-scratch/terminal-osc-review/native-invalid-json.log. No implementation fix or push.OSC-R02 P1: shim clipboard targeting survives socket replacement incorrectly. session.rs:1076 finds the recipient by retained Inputs.typing_writer (inputs.rs:104), without a socket typing fence. Writer 1 types, disconnects; replacement selects writer 1 and replays duplicate input only; a later live OSC52 effect is assigned to the replacement despite no newly accepted typing. Bit-6 contract forbids replacement delivery. Failing test replacement_socket_without_new_typing_does_not_receive_clipboard uses real Unix sockets and durable cursors: 0 passed, 1 failed, 112 filtered. Committed locally on review-terminal-osc; receipt ~/.cache/codex-scratch/terminal-osc-review/replacement-direct.log. No implementation fix/push.

f642a80f(two local test-only commits:def0f072,f642a80f). OSC-R02 is P1, OSC-R01 is P2. Correction to earlier test count: replacement regression has 107 filtered, not 112. Production browser clipboard functional spec: 1 passed. Sanitized existing terminal_osc fuzz target: 564,964 generated inputs, no crash/assertion failure; this is functional fuzz coverage, not a timing/RSS measurement. No visual judgment or perf VM use.

Continuation r4 started on branch terminal-osc, base/head
83e8202031. Read #209 history and #206 cross-reference; no parent named. Review findings def0f072/f642a80f will be reproduced before minimal fixes: retain pending MCP calls through JSON decoding; bind OSC52 authority to new typing on a live socket rather than a durable writer alone. No deploy/UI; push only terminal-osc. Existing scripts/verify does not implement iterate; use touched-package gates while working and full fast on final head. Preserve D243 exact static caps (22145424 x86_64, 19527768 ARM64), reporting measured deltas.OSC-R01 fixed and pushed in
62148415(imports regressiondef0f072). Pending native calls remain reachable until decoding/settlement, so malformed UTF-8/JSON closes the channel and rejects pending calls. Original test reproduced 0 pass/1 fail (pending after channel close); fixed MCP suite 4 pass/0 fail/25 assertions. Test now awaits the asynchronous server close callback, retaining both rejection and closure assertions. bun run check and cargo fmt --all --check pass. No dependency/wire/Rust production change.mcp-red-r4.log
mcp-green-r4.log
OSC-R02 reproduced on this branch before fixing: 0 passed/1 failed/107 filtered; replacement received clipboard after duplicate-only replay. Source fix adds one u64 socket-local accepted-input fence, set only when handle() accepts new bytes; delivery also requires equality with the current durable typist cursor. This rejects ordinary replacement and shared-writer handoff without new ordinary typing. No protocol/dependency/timer change. Added actual handle/PTY coverage for shared new typing, duplicate replay, new ordinary typing and replacement recovery; removing the fence makes it fail (0 passed/1 failed/108 filtered). Full shim tests, clippy and static size checks are running; no completion claim. scripts/verify iterate returned unknown verification mode, so touched-package gates substitute during work.

Full shim unit suite: 96 passed, 0 failed, 13 ignored, including both fidelity corpora. Real native mouse integration initially failed because the direct Cargo invocation lacked zig in PATH (FileNotFoundError); pinned-Zig rerun passed 1/1. Full fast sets that PATH itself.

Production-viewer clipboard functional regression on
2289ef7f: 1 passed. Focused live events write to the OS clipboard; unfocused events and raw OSC output leave it unchanged; an OS refusal does not fall back to a legacy write. Existing Playwright harness, unique TRACER_TEST_PORT=4409, Browser plugin unavailable. Receipt/screenshot are functional evidence only; no visual-quality or build-host performance claim. No UI source changed. Static sizes and final fast remain pending.clipboard-browser-r4.log

First r4 shipping x86 build (
2289ef7f): 22146192 B vs unchanged 22145424 B cap, +768 B. Compared with the reviewer original artifact: .text +640 B, .eh_frame +92, .eh_frame_hdr +8, exception table +24; no new dependency/profile/native source. This is not a passing size result. Cut under validation: retain (writer, accepted cursor) at the already successful input acceptance, removing the added writer-store hash lookup during clipboard delivery. Socket-local fence and replacement/shared/replay semantics stay identical; test/clippy running. Do not raise the cap.size-attribution-r4.txt

Source cut committed/pushed in
83076e54: Inputs retains (writer, accepted cursor) on successful new input, and clipboard delivery compares that directly with the live socket's fence. No hash lookup in effect dispatch, no allocation/dependency/wire/profile change. Both imported regressions stay green: session tests 17 passed/3 measurement tests ignored, input tests 2 passed, shim all-target clippy and fmt passed. Initial x86 artifact at2289ef7fwas +768 B over the unchanged cap; source-cut remeasurement is queued behind ARM. No size waiver. Final fast and real-process status/clipboard/restart fixtures remain required before handoff.Committed/pushed
3962ea95: reuse the attachment byte for pending/ready/typed, and the existing typist slot for a non-owning socket descriptor. Only new accepted ordinary input binds that socket; shared input withdraws eligibility. Ready state rejects descriptor reuse by an untyped replacement. No added scalar storage, allocation, dependency, wire or profile change. All 18 session tests (3 measurement tests ignored), 2 input tests, shim all-target clippy and fmt pass. The published cursor fix remained correct, but ARM at83076e54was 19528024 B (+256 over unchanged 19527768 cap), motivating this representation.An unpublished writer-id-plus-typed-phase experiment failed a new real-PTY test: a successor accepts new typing, then a malformed trailing Attach rejects it; the former ordinary peer survives and must not regain clipboard authority. 0 passed/1 failed before descriptor binding; now passes. The imported replacement test also drives actual acceptance/replay and forces a stale descriptor match, independent of parallel FD allocation. Only this job's superseded x86 candidate compiler descendants were stopped by PID before rebuilding. Final static remeasurement, real-process fixtures and full fast remain pending; no size waiver or completion claim.

d46d6e2f: record the last typing socket descriptor once, qualify only that socket at delivery (shared/unnegotiated/parked sockets yield no recipient), and remove redundant writer presence from Typed state. The same socket/reuse/rejected-successor invariants remain; all 18 session tests, all-target shim clippy and fmt pass. No interface/dependency/allocation/profile change.3962ea95x86 artifact was 22145552 B (+128 over unchanged cap); final remeasurement is queued behind its ARM build. Caps remain unchanged. Final fast and real status/clipboard/whole-server-restart fixtures still required before handoff.Committed/pushed
272feadc: Inputs::accept returns whether the queue grew, replacing dispatch's redundant second writer hash lookup. The return is true exactly for new accepted bytes; replay/empty input stays false, refusal stays atomic. All 18 session and 2 input tests, all-target shim clippy and fmt pass.d46d6e2fx86 was 22145488 B (+64 over unchanged cap); ARM matched 19527768 B.

Each passed a fresh serial exact-test rerun with unchanged limits (1/1 each). This is not a gate waiver; a fresh final-head fast remains required. No restart source or timeout changed. Milestone static stage is still running.Auto-continuation r4 resumed on terminal-osc at
272feadcc2(base/head). Worktree clean; both reviewer regressions already imported/fixed and pushed. Continuing pending shipping size checks, full head fast gate and real-process status/clipboard/restart coverage. No UI or deploy; no parent on #209; #206 cross-reference read. Existing verify has no iterate mode; touched-package gates substitute.Committed
83a6b925: represent absent clipboard typist by invalid descriptor -1 (live descriptors are nonnegative), removing optional-tag dispatch without changing socket authority/reuse fences. All 18 session tests passed (3 measurement tests ignored), shim all-target clippy and fmt passed. Latest pre-cut artifact at272feadc: x86 22145488 B (+64 over unchanged cap), ARM 19527768 B (matches cap); no waiver. Shipping remeasurement and fresh full fast are running on head, serial Rust tests to avoid subprocess contention.Committed/pushed
a44741e7: select the unique typing descriptor before qualifying its socket; no ineligible fallback. All 18 session tests, shim clippy and fmt pass. Sentinel candidate x86 remained 22145488 B (+64), so shipping remeasurement continues with caps unchanged.Milestone fast at
83a6b925failed whole-server fixture at MCP URI notification; a direct debug retry failed at API subscription. Same fixture against the shipping release binary passes all API/MCP/subscription/foreign-account/whole-server restart/reattach checks. No deadline or production behavior changed and no host-load waiver claimed. Stopped only the owned failed gate tree (PID 3600720) and unnecessary feature-specific rebuild (3690646); fresh full head fast now runs in CPUWeight=10000 scope with serial tests. Original full log: ~/.cache/codex-scratch/terminal-osc/evidence/verify-fast-head-r4.log; release proof: restart-notification-release-r4.log.Committed/pushed
7f8aae72: reuse existing invalid_input constructor for range/overflow/full-queue refusals, removing duplicate error code/text. InvalidData and atomic cursor/queue behavior stay unchanged; diagnostic now consistently says invalid shim writer input. All 18 session tests, shim all-target clippy and fmt pass.a44741e7x86 remained 22145488 B (+64 over unchanged cap), so this shipping cut is under remeasurement.Fresh weighted milestone at
a44741e7passed whole-server API/MCP restart+reattach, daemon restart, two-writer clipboard, metadata-socket reconnection/disable and the earlier restart regressions. No timeout altered.

Caps unchanged, no waiver/completion claim.Committed/pushed
a73e8a13: mark only invalid_input cold/non-inline, retaining shared error construction outside successful input code. All 18 session tests, all-target shim clippy and fmt pass. The preceding7f8aae72shipping x86 remained 22145488 B (+64), despite removal of the duplicate diagnostic; section alignment absorbed the data cut. No ceiling, profile, dependency, normal-path call or behavioral change. New static remeasurement running; final-head full fast still required. Stopped only own superseded ARM build PID 4040317 before compiling the new source.a73e8a13shipping x86 now 22145360 B: -64 vs unchanged 22145424 cap, -128 vs preceding r4 candidate. Text section 0x10659f4 -> 0x1065974 (-128); cold helper introduces one shared refusal path, without a valid-input call. Native key-memory check passes. D243 requires ratcheting the x86 cap down to 22145360; ARM measurement is in progress before the atomic cap/docs update and final immutable-head fast. No size waiver.Committed/pushed
7da9d662: D243 caps/docs ratcheted to shipping measurements x86 22145360 B (-64 vs r3 / -90240 vs round 1), ARM 19527640 B (-128 vs r3 / -138112 vs round 1). Exact-cap, +1-byte refusal and smaller-artifact ratchet tests pass for both targets; fmt and shell syntax pass. No profile/dependency change.Milestone fast: fmt, native fmt, compile-out, clippy, all workspace tests and cargo-deny PASS; static row fails solely because both smaller artifacts require this ratchet. Native key-memory check passes; no ARM runtime claim on x86. All final shipping-artifact functional fixtures pass in weighted serial runs: status detach/restart/reconstruct; write-only single-typist clipboard with consent/revoke; API/MCP/subscription/account isolation/whole-server restart/reattach. Earlier parallel optional shipping fixtures hit deadlines (clipboard output, server replay fence), then same unchanged limits pass serially; no waiver. Fresh immutable-head fast is running with port 4409 and serial tests.
7da9d662full fast passed both exact static caps/key-memory/boundary checks, but failed whole-server test at reattach replay fence; no waiver. One diagnostic run then saw replay + Ack26 followed by socket closure. Six subsequent weighted serial debug fixtures passed unchanged limits. Cause remains unproven; no production behavior/deadline change. New test-only diagnostics retain server exit state, WebSocket close code, frame kinds and byte count without credentials/program text. Strict TS check and all 4 MCP tests pass. Committed/pushed diagnostic step; fresh full head fast running. Both reviewer fixes and shipping sizes remain unchanged.R4 fixes and final verification finished on terminal-osc, head
d621a5a58b; pushed and remote SHA confirmed. Worktree clean. Stop for independent verification; no deploy or issue closure.OSC-R01: successful malformed native results retain their pending call until decoding/settlement, so channel shutdown rejects it. OSC-R02: clipboard authority follows the socket that accepted new typing; replacement/replay, shared typing, reused descriptors and a rejected successor cannot inherit or restore it. Both imported regressions pass. Atomic fix/size/diagnostic commits are on the branch; no dependency, wire or speed-profile change.
Both exact ceilings ratcheted down. Exact/+1-byte/smaller-artifact boundary tests pass. Native x86 key-memory check passes; ARM runtime is not claimed on this host.
Final full scripts/verify fast: VERIFY_EXIT=0. All Rust rows PASS; MCP 4/4 including malformed-result rejection, production tracer/build/transfer and protocol tests PASS. Port 4409, one test thread, CPUWeight=10000 scope. Shipping-artifact fixtures also pass: status detach/daemon restart/reconstruct; write-only clipboard consent/two-writer single-typist delivery/read refusal/revoke; API/MCP/subscription/account isolation/whole-server restart/reattach. No build-host runtime performance claim.
Reliability limit retained for review: earlier full gates intermittently failed this existing whole-server fixture at initial notification or reattach. One diagnostic run observed socket closure after replay and input Ack; six later weighted serial reruns and this final full gate passed unchanged limits. Cause remains unproven;
d621a5a5adds content-free lifecycle diagnostics, not a production fix or a deadline waiver. Failed receipts are attached. Prior maximum-state node RSS (18,060 KiB at 50x64 maximum records) remains above the 15 MiB target; it was not remeasured or claimed solved here. Other OSC inventory/recommendations remain the earlier #209 table, with global query authority/synchronized paint in #206.Author checklist: socket-vs-durable-writer authority, duplicate/refused input atomicity, descriptor reuse, shared/rejected successors, clipboard consent/focus/replay isolation, malformed-result settlement, restart/metadata recovery, bounded state, plugin compile-out, module docs, license and exact artifact caps reviewed. This is author verification, not an independent correctness/visual verdict. Temporary owned build targets will be removed after the gate; attached evidence stays outside the checkout.

This lane reduces the base binary by about 92–94 KB, while the advisory patch contributes 1,568 B on the shipping artifact. I’m leaving D243 ceilings unchanged; adjusting a measured ceiling requires the owner’s D243 decision. Receipts: origin/dev bloat report, exact size comparison.
