Upgrade the existing libghostty-vt integration to its 1.0 release while retaining D94's engine choice.

Scope: inventory current extracted Zig sources, sed patches and adapter dependencies; use the stable public C API wherever it covers current behavior; build the signed source and dependency tarball offline in Nix; retain justified internal patches; compile out unused features; update Zig and Linux/macOS build paths; measure before/after throughput, snapshot cost, RSS at 1/50/200 sessions and static size for x86_64/aarch64; run terminal, real-server and shim process-per-user gates; audit the dependency SPDX licence manifest.

Constraints: branch libghostty-vt-1.0 from origin/dev; do not merge or deploy. Stop and ask on this issue if the release/API requires a foundational design choice. Do not change numbered decisions.

Starting J339 on branch libghostty-vt-1.0, based on origin/dev at 3644950b8e4b5dddeefba350f97a3892189ca193.

Plan and estimate: (1) inventory current Zig extraction, patches, adapter symbols and 1.0 C API coverage, and capture the before baseline (about 2 hours); (2) upgrade the signed source/deps inputs and offline Nix package, then migrate the adapter and remove only API-replaced patches (about 3–4 hours); (3) add compile-out flags and update Zig/Linux/macOS integration (about 2 hours); (4) run the paired performance, licence and requested terminal/server/shim test matrix, then the final gate (about 3–4 hours plus VM queue time). Estimated 10–12 active hours. Each source/API, patch-removal, feature-flag and Zig/Nix/macOS slice will be committed atomically and pushed to this branch.

If 1.0 cannot expose required behavior through its supported C API and continuing would require choosing a different engine or terminal-state design, I will record the evidence here and stop for kayg's decision. I will not change D94 or D213.

Finding 1 — upstream's package contract is more specific than the current source pin. The version-matched PACKAGING-LIBGHOSTTY.md at tag vt-1.0.0 says to use the signed source and matching -deps.tar.gz from https://release.files.ghostty.org/libghostty-vt/1.0.0/, verify Minisign signatures with the published key, unpack the deps in Zig's cache layout, and pass them through --system for a network-free build. It lists Zig 0.17.0 as the minimum for 1.0.0 (any 0.17.x), and documents -Dvt-features for compile-out. The GitHub tag page itself has only generated GitHub source archives; the version-matched packaging guide identifies release.files as the release source. Current D213/build pins are 0.15.2.

Reference mismatch: fj issue view 259 is currently titled “Sidebar account pill drifts up from the bottom; rename Mesh hosts by double-tap”; it contains no Zig/macOS SDK report. I will trace and reproduce the Mac build issue from the current build path and report its actual evidence here.

Progress — Rechecked both build-slot queues before the baseline. The architecture-neutral quick run is queued on dev-02-std (position 4; 86 GB free) in /home/claude/worktrees/j339-libghostty-vt-1.0 with CARGO_INCREMENTAL=0. Log: /home/claude/.cache/codex-scratch/j339/evidence/verify-quick-baseline.log. The earlier compute01 baseline was still waiting and was cancelled before it entered a slot.

Issue-reference check: the task mentions #259 for the Mac Zig failure, but Forgejo currently identifies #259 as the sidebar account-pill/Mesh rename request. The Mac Zig release failure is tracked as #366 (J243). I will use #366 and its receipts for the macOS build fix while keeping this upgrade scoped to #419.

Baseline quick pre-check attempt on dev-02 acquired a slot but exited before the gate with env: scripts/verify: No such file or directory; the launcher inherited /home/claude as its cwd. I am correcting the cwd, confirming the worktree base and both queues, then will rerun. No baseline build/test evidence was produced by this attempt.

Integration inventory (base bfe0b02f39): scripts/build-vt pins Git archive a887df42c56f6de86c0fe6da9c4eeca37931e083 / fb4b2f9f… and extracts src/lib_vt.zig, src/terminal/PageList.zig, src/terminal/page.zig, src/terminal/Screen.zig, src/terminal/compress/lz4.zig, src/terminal/compress/Page.zig, src/build/GhosttyLibVt.zig, and build.zig. Engine sed edits remove ghostty_sys_set and ghostty_sys_log_stderr, redirect the sys log callback, add function/data sections, and strip ReleaseFast objects. The Nix sed changing Cargo vendor paths is separate from the VT engine.

The Python edits route Linux page-pool allocations through our allocator; reduce preheat 4→1 and change pool geometry/ownership; check allocation headroom and evict history; bound wider-resize history before reflow; avoid touching freed cursor pins on resize failure; keep LZ4 bounds checks in release; and optionally add our exact cold-history codec to compress/Page.zig. The build patch avoids constructing the full benchmark/app graph, while the build-module patch enables section GC and stripping.

Rust currently calls ghostty_terminal_new/free/vt_write/resize, ghostty_terminal_mode_get, and ghostty_terminal_get; custom exports are infraternal_vt_approximate, _snapshot, _compare, _compact, and _screen_pages. The Zig adapter reaches terminal/c/terminal.zig (Terminal), terminal/main.zig (Terminal, Screen, Page, cell/row/style types), ScreenSet, PageList.Pin/row iterators, modes.Mode/ModeTag/ModeState, charsets and Unicode tables. 1.0 covers lifecycle, typed data via ghostty_terminal_get, configuration via ghostty_terminal_set (including scrollback max bytes), custom allocation and public compression. It does not provide our bounded approximate/faithful VT repaint format, test-only exact state comparator, or pre-construction page-floor geometry. Public screen/render getters do not expose all inactive-screen, saved-cursor, tabstop/charset and semantic state the D94 fixture contract checks. The new custom allocator also cannot intercept Linux page backing while PageList.pageAllocator selects std.heap.page_allocator; I verified that source path in 1.0. Mouse input encoding is used only by the native probe, so production can compile it out with a separate test opt-in.

Corrected baseline pre-check on dev-02: scripts/verify quick completed at base bfe0b02f39. Verbatim summary: QUICK pre-check passed. This is not the gate: run scripts/verify fast before reporting done. Its scope guard reported workspace=0, packages=[], tracer=0, so it was a clean no-diff pre-check.

Branch update: libghostty-vt-1.0 was fast-forwarded from bfe0b02f3 to current origin/dev af033d0b4 before implementation. The earlier x86_64 baseline build remains isolated on its BFE-based VM worktree and is queued on compute01 (PID 1624423). The allocator ABI red test is queued first on dev-02 (PID 3335225) behind the current Rust build.

Finding: the signed 1.0 source and deps archives recheck against their pinned SHA-256 values. The upstream package contract confirms Zig 0.17.0, --system for offline dependencies, and an empty ZIG_GLOBAL_CACHE_DIR. Receipt: /home/claude/.cache/codex-scratch/j339/evidence/upstream-contract.txt (SHA-256 1df6eafd38a7ae10f4d790a537dd54e09f5565d2e522c5255e090d4dbbfbec79). The 1.0 C API covers terminal lifecycle and I/O, option 28 for scrollback bytes, data 15 for history rows, and data 37 for mode state; the allocator vtable reserves four trailing null pointers. The source also guards GhosttyBench.init with config.emit_bench at build.zig:124-127, so the old benchmark-graph patch that fixed the Mac cold-fetch failure is unnecessary with this release.

Next: complete the red check, migrate the FFI and source pin, then remove patches one at a time, add release feature flags, and update the Zig/Nix/macOS path. The #366 evidence identifies the prior Mac failure as Zig resolving the unused app benchmark dependency graph; the 1.0 package contract and deps tarball let the same offline build path run on Linux and macOS.

Crash-safety checkpoint pushed: 7f426be94 (WIP: stage libghostty-vt 1.0 ABI migration (#419)). It contains the signed release artifact hashes/signature hashes and the allocator ABI assertion, still ahead of its implementation.

Correction from the first ABI test attempts: the test lives in terminal_memory, which lib.rs only compiles on Linux with process-per-user. The default-feature command therefore selected zero tests (122 filtered out). The properly feature-gated red run is now queued on dev-02 as PID 3345775; the x86 baseline static build is running in its separate BFE worktree on compute01. Neither result is claimed yet.

Finding: with the required process-per-user feature enabled, the new ABI test fails on the old allocator table: size_of::<Vtable>() is 32 bytes but the 1.0 allocator ABI requires 64 bytes for four callbacks plus four reserved pointers. The initial default-feature filter selected zero tests because terminal_memory is gated by process-per-user; the corrected filter ran exactly one test and failed at the intended assertion. See allocator-abi-red.log.

Finding: the focused process-per-user ABI build exposed one direct test-only caller still using the pre-1.0 creation options. cargo test --locked -p infraternal-shim --features process-per-user --lib allocator_vtable_includes_stable_reserved_slots -- --nocapture failed to compile at tests/unit/allocation.rs:106-114 with E0422/E0061 because the 1.0 C API takes cols, rows and applies scrollback through ghostty_terminal_set. I am migrating this allocator fixture to exercise the same stable path before rerunning it.

Finding — the partial 1.0 build recipe still references undefined $archive and pre-release archive member paths in the shared-host block (tar -xOf "$archive" "ghostty-$version/..."), even though the signed source is already unpacked at $source_dir. The local 1.0 tarball and PACKAGING-LIBGHOSTTY.md confirm the normalized paths are src/terminal/...; this prevents a shared-host build before Zig starts. Next I am aligning the recipe to the extracted 1.0 tree, validating each retained internal patch against the 1.0 source, then running the feature-gated ABI and terminal tests on the VM. The prior estimate remains 10–12 active hours total; roughly 6–8 remain, excluding VM queue time.

Finding — the new macOS VT build still calls sha256sum unconditionally while generating its cache key (scripts/build-vt:94,107). sha256_check has a shasum fallback, but the cache-key path does not; macOS ships shasum, not sha256sum. This will stop the requested Mac build before Zig runs. I will make cache hashing use the same portable helper and add a regression check before the Mac run.

Finding — the existing vt_compare Ghostty branch measures the registry wrapper libghostty-vt 0.2.2, not the shim adapter being upgraded. The harness constructs the old Rust Options/Terminal API and formats through Formatter; the new production path calls the stable C ABI directly from terminal_native.rs. I will adapt the requested throughput and snapshot measurements to exercise that production path so the after numbers are comparable to the same 1.0 build.

Correction to the cache-hash finding: the supported scripts/macos-build-check path runs inside nix develop, and the Nix build environment supplies GNU coreutils, so sha256sum is available there. I overstated this as a blocker for the requested Mac build. I will validate that supported path under the Mac lock and only change the hashing code if the Mac preflight demonstrates a failure.

Measurement-path correction: the existing ignored release probes in crates/infraternal-shim/tests/unit/terminal_budgets.rs (measured_parser and snapshot_200x60) exercise the shim's Terminal and native adapter, and crates/infraternal-shim/tests/vt_scale.py drives real shim sessions at a caller-selected count while reporting per-process RSS/PSS and socket snapshot latency. These are the requested production-path measurements, so I will use them instead of changing vt_compare or adding another benchmark API; vt_compare remains a comparison-only tool.

Base update: fetched origin/dev at 21b3c84ced, which had advanced 23 commits from the job base. Rebased the branch and pushed the checkpoint as c20d27e65 using force-with-lease. The implementation diff remains preserved locally. The queued quick attempt on dev-02 acquired a slot but stopped before checks because SSH left the command in /home/claude; log: /home/claude/.cache/codex-scratch/j339/evidence/verify-quick.log. I am correcting the worktree cwd and rerunning quick.

Finding: the rebased quick gate reached the signed 1.0 release build, then Zig 0.17.0 rejected the old --global-cache-dir build argument. The recipe already sets ZIG_GLOBAL_CACHE_DIR, which is the supported cache configuration; I will remove the obsolete CLI argument and pin that expectation in the build-recipe test. Evidence: /home/claude/.cache/codex-scratch/j339/evidence/verify-quick-lz4.log.

Evidence: /home/claude/.cache/codex-scratch/j339/evidence/verify-quick-lz4.log.

Finding: with the source recipe fixed, the pinned 1.0 build now reaches our snapshot adapter and reports three upstream-type errors: Zig 0.17 deprecates std.meta.fields, and Style.Color is now a packed struct with palette/rgb/value methods. The stable C ABI does not expose the faithful snapshot state, so this existing adapter remains necessary and must be ported to the 1.0 internal types. Evidence: /home/claude/.cache/codex-scratch/j339/evidence/verify-quick-zigflag.log.

Finding detail: the 1.0 snapshot compiler errors showed Zig 0.17 enum reflection has field_names and field_values, and the cell palette index is color_palette.data inside a packed record. The adapter now reads those exact fields; the build-recipe test pins these 1.0 compatibility points. Evidence: /home/claude/.cache/codex-scratch/j339/evidence/verify-quick-snapshot.log.

Adapter verification finding: the saved-mode reflection loop now binds name, value, but the body still references field.name at crates/infraternal-shim/native/snapshot.zig:74. The latest verify-quick-adapter2.log reports use of undeclared identifier 'field'. I added a focused assertion to scripts/test-build-vt-pinned.py and confirmed it fails on the current tree on dev-02 (exit 1 at that assertion). I am correcting the stale identifier to the bound name, then I will rerun the recipe check and native build.

Feature-flag finding: the pinned 1.0.0 Features.parse tests and PACKAGING-LIBGHOSTTY.md spell the option input-encode (the Zig struct field is input_encode), but scripts/build-vt currently passes +input_encode for the native mouse probe. The release source confirms this at src/terminal/build_options.zig:254 and the packaging guide at line 469 in /home/claude/.cache/codex-scratch/j339/libghostty-vt-1.0-inspect/source. I am adding a recipe assertion for the CLI spelling before changing it; the normal -all shipping build remains unaffected.

Quick-check finding: after the two native fixes, scripts/verify quick reached workspace clippy and stopped because TERMINAL_DATA_SCROLLBACK_ROWS in terminal_native.rs:24 is unconditional but its only reader, history_rows, is compiled only for tests or process-per-user. Rust reported constant ... is never used under -D warnings; the full evidence is /home/claude/.cache/codex-scratch/j339/evidence/verify-quick-fixed.log (QUICK_EXIT=1). I will add a recipe assertion for the matching cfg, demonstrate its red result, then cfg-gate the constant and rerun quick.

Finding — the Zig 0.17 native-target compatibility patch currently exists only in nix/package.nix’s Linux release-binary derivation. flake.nix gives the dev shell nix/zig.nix’s unmodified .unpacked compiler as INFRATERNAL_ZIG, scripts/build-vt copies that compiler unchanged, and scripts/macos-build-check runs under nix develop. The macOS build path therefore does not receive the patch. I will put the shared compiler patch in nix/zig.nix and use that result in both paths, then validate it on the Mac VM under the requested lock.

Correction — I conflated the package-only native-target workaround in nix/package.nix with the Mac failure. The #366 evidence identifies the Mac failure as a cold fetch of unused app/benchmark dependencies; libghostty-vt 1.0 gates that graph behind emit_bench, and scripts/build-vt uses the same signed --system dependency bundle for Linux and macOS. The package.nix Module.zig adjustment is for Nix build-host discovery and is not evidence of a Mac SDK failure. I will leave that compiler adjustment scoped to the Nix package path unless the locked Mac build reproduces a native-target error.

Process correction: the common brief says code is for editing only and all builds/tests run on the VMs. I stopped the local Cargo/Zig run after rereading it. Those results will not be used as verification; future build/test evidence will come from the assigned VMs.

Finding: source tracing in the pinned 1.0 Terminal.zig shows grapheme extensions return without updating previous_char, so the REP source remains the edge cell's base codepoint. The pending-wrap serializer had compared against the final grapheme extension; its extra wrap-disabled print then cleared pending_wrap. I changed the predicate to compare the base codepoint and removed temporary diagnostics. VM verification is pending.

Workspace/capacity blocker: compute01 has all five slots busy. Its existing worktrees/j339-libghostty-vt-1.0 is at af033d0 and has 13 modified files outside this task, so I will not reset or reuse it. dev-02 has its J339 checkout at c20d27e but only 37 GB free against the 40 GB floor. No VM build is queued; I will use a clean checkout when a VM has both a slot and headroom.

Finding: the VM-side scripts/test-build-vt-pinned.py red run exits 1 at the new shared-output assertion. crates/infraternal-shim/build.rs explicitly emits cargo:rustc-link-lib=static=ghostty-vt, so deleting the release .so/.dylib cache outputs is unnecessary and discards the 1.0 shared build. I am removing that cleanup while retaining static selection in Cargo.

Finding — history_rows() currently returns zero for every non-success status from stable C data getter 15. That includes GHOSTTY_UNSUPPORTED (-8), which result.zig in the signed 1.0 source defines explicitly; user_host.rs publishes this value as native_history_rows. The current behavior hides a missing getter or ABI mismatch as an empty history. I will propagate the error and test that unsupported stays distinct.

Finding: the 1.0 snapshot replay cases for an orphaned spacer head and charset-shifted wide text are representable. On dev-02, cargo test --locked -p infraternal-shim --lib fidelity reported both fidelity_orphaned_spacer_head_after_region_scroll_replays and fidelity_charset_shifted_wide_text_replays as ok; their old rejection expectations were stale.

The same run exposed the semantic-tail mismatch: 26 passed, 2 failed, 4 ignored. fidelity_semantic_validation_matches_exported_history_extent and one fidelity_extended_smoke case differed only at state code 6200001. libghostty-vt 1.0 retains Screen.semantic_prompt.seen after prompt output even when the marked row is outside the bounded export tail. The serializer now rejects click settings, live cursor semantics, and retained row/cell metadata while allowing that historical aggregate. The strict oracle has been narrowed to compare the full click union and live cursor fields, ignoring only seen; the green rerun is in progress.

Snapshot finding update: the strict oracle compares semantic_prompt.click with structural union equality and still checks live cursor semantics; it omits only the history-wide seen aggregate. The focused replay suite is now green on dev-02: cargo test --locked -p infraternal-shim --lib fidelity → 28 passed, 0 failed, 4 ignored, 91 filtered. This includes the 400-line omitted-history case, the extended corpus case that exposed the same aggregate mismatch, spacer-head replay through continuations/resizes, and charset-shifted wide-text replay.

Integration inventory, audited against the pre-upgrade recipe at 21b3c84ce:

  • The library-specific sed -i patches were: (1) in session-image builds, remove the ghostty_sys_set and ghostty_sys_log_stderr exports and redirect logFn to the shim logger; (2) add link_function_sections and link_data_sections; (3) in ReleaseFast, set root_module.strip. The stable 1.0 C API/build options make these unnecessary. The separate nix/package.nix sed only rewrites the temporary Cargo vendor-directory path; it does not patch libghostty.
  • After unpacking the revision archive, the old build re-extracted: src/lib_vt.zig, src/terminal/PageList.zig, src/terminal/page.zig, src/terminal/Screen.zig, src/terminal/compress/lz4.zig, src/terminal/compress/Page.zig, src/build/GhosttyLibVt.zig, and build.zig. The 1.0 path extracts the signed source and offline deps tarballs once.
  • Stable C API symbols used by Rust: ghostty_terminal_new, ghostty_terminal_free, ghostty_terminal_vt_write, ghostty_terminal_resize, ghostty_terminal_set, and ghostty_terminal_get. It covers lifecycle, VT input, resize, typed scrollback option 28, and data keys 15 (history rows) and 37 (test mode config); GHOSTTY_UNSUPPORTED maps to Rust ErrorKind::Unsupported.
  • Custom exports retained: infraternal_vt_snapshot, infraternal_vt_approximate, infraternal_vt_compare, infraternal_vt_screen_pages, and the feature-gated infraternal_vt_compact. They keep the VT escape-sequence resume format, approximate fallback, differential test oracle, shared-host reservation sizing, and optional cold-history experiment. The release's binary snapshot API cannot replace our existing VT wire format.
  • Direct snapshot types include vt.Terminal, vt.Screen, Screen.CharsetState, Screen.SavedCursor, PageList.Pin, page.Cell, Style, modes.Mode/ModeState/ModeTag, CharsetSlot, and terminal.hyperlink.Hyperlink. The memory adapter uses the C allocator, terminal.mem, and page.Page capacity/layout. The compact-history experiment uses page.Page/Cell/Row, PageList.compress, and the LZ4 codec. Remaining patches are guarded: shared-host allocation/accounting and resize bounds, runtime LZ4 safety for bounded restore, and compact-history encoding/driver because no C API operation exposes cold pages.

The separate `nix/package.nix` `sed` only rewrites the temporary Cargo vendor-directory path; it does not patch libghostty. - After unpacking the revision archive, the old build re-extracted: `src/lib_vt.zig`, `src/terminal/PageList.zig`, `src/terminal/page.zig`, `src/terminal/Screen.zig`, `src/terminal/compress/lz4.zig`, `src/terminal/compress/Page.zig`, `src/build/GhosttyLibVt.zig`, and `build.zig`. The 1.0 path extracts the signed source and offline deps tarballs once. - Stable C API symbols used by Rust: `ghostty_terminal_new`, `ghostty_terminal_free`, `ghostty_terminal_vt_write`, `ghostty_terminal_resize`, `ghostty_terminal_set`, and `ghostty_terminal_get`. It covers lifecycle, VT input, resize, typed scrollback option 28, and data keys 15 (history rows) and 37 (test mode config); `GHOSTTY_UNSUPPORTED` maps to Rust `ErrorKind::Unsupported`. - Custom exports retained: `infraternal_vt_snapshot`, `infraternal_vt_approximate`, `infraternal_vt_compare`, `infraternal_vt_screen_pages`, and the feature-gated `infraternal_vt_compact`. They keep the VT escape-sequence resume format, approximate fallback, differential test oracle, shared-host reservation sizing, and optional cold-history experiment. The release's binary snapshot API cannot replace our existing VT wire format. - Direct snapshot types include `vt.Terminal`, `vt.Screen`, `Screen.CharsetState`, `Screen.SavedCursor`, `PageList.Pin`, `page.Cell`, `Style`, `modes.Mode`/`ModeState`/`ModeTag`, `CharsetSlot`, and `terminal.hyperlink.Hyperlink`. The memory adapter uses the C allocator, `terminal.mem`, and `page.Page` capacity/layout. The compact-history experiment uses `page.Page`/`Cell`/`Row`, `PageList.compress`, and the LZ4 codec. Remaining patches are guarded: shared-host allocation/accounting and resize bounds, runtime LZ4 safety for bounded restore, and compact-history encoding/driver because no C API operation exposes cold pages. The signed release manifest is `deps/libghostty-vt-third-party.json`. Its six entries and SPDX expressions are `aro: MIT AND Unicode-3.0`; `highway: Apache-2.0 OR BSD-3-Clause`; `simdutf: Apache-2.0 OR MIT`; `translate_c: MIT`; `uucode: MIT AND Unicode-3.0`; `wuffs: Apache-2.0 OR MIT`. All are permissive and AGPL-compatible.

Progress: committed and pushed 7a5fd8809 on libghostty-vt-1.0 (original branch base 21b3c84ce). The snapshot fidelity gate on dev-02 passed: cargo test --locked -p infraternal-shim --lib fidelity → 28 passed, 0 failed, 4 ignored. The spacer-head, charset-shifted wide-text, semantic-tail, and extended replay cases are included.

The compact-history RED is confirmed: the feature test fails at link time because infraternal_vt_compact is absent. I added the internal PageList driver and feature-gated export; its green run is queued on dev-02. Next: finish the offline build fixture, capture paired measurements, run terminal and server gates, then rebase and split the remaining commits.

Finding: the black-box recipe fixture omitted scripts/zig.sha256 even though scripts/auth-toolchain reads that pin before accepting the fake compiler. The first dev-02 run failed with: awk: cannot open "/tmp/nix-shell.3hpOLx/build-vt-fixture-w667dgj2/repo/scripts/zig.sha256" (No such file or directory). The fixture now copies the pin.

Finding: the fixture wrote literal backslash-n sequences into release metadata, so the recipe could not find libghostty-vt-1.0.0.tar.gz in its generated checksum manifest. The rerun failed with no pinned checksum for libghostty-vt-1.0.0.tar.gz. I corrected the fixture line endings and made the bad-checksum case use a fresh target with corruption enabled before the first archive fetch, so a cached valid download cannot mask the check. Final fixture receipt: /home/claude/.cache/codex-scratch/J339/evidence/build-vt-fixture-green.log, which reports both expected PASS lines and exit=0.

Mac linker root cause (receipts: /Users/claude/.cache/codex-scratch/J339/evidence/mac-link-repro.log and mac-native-symbols.log): the release install contains both libghostty-vt.a and libghostty-vt.dylib; nm shows _infraternal_vt_approximate, _infraternal_vt_compare, and _infraternal_vt_snapshot in the archive but not the dylib. Rust emits -lghostty-vt with the combined library directory, and the focused test fails to resolve those adapter symbols. I will give Cargo a static-only search directory containing the .a, leaving the release lib/ outputs and pkg-config files intact.

Measurement correction: the first after parser sample used a process-per-user test binary (244 tests in its harness), while the baseline harness has 128 tests and was built with default features. That feature mismatch makes 119.82 MB/s non-comparable; I am rebuilding the after harness with the baseline feature set. Invalid sample is retained at /home/claude/.cache/codex-scratch/J339/evidence/perf-after-parser.log and will not be used in the before/after table.

Finding: libghostty-vt 1.0 changed the DCS payload boundary semantics (branch head before this fix: 34b8265a98).

The signed 1.0 source's terminal/parse_table.zig test explicitly requires every high byte 0x80–0xff in dcs_passthrough to stay payload data. Our terminal_limits currently normalizes C1 bytes whenever it is outside Ground or OSC, so it rewrites DCS payload bytes 0x90 and 0x80 as ESC P and ESC @. That ends the DCS and lets payload text become visible.

I added a focused regression for ESC 0x90 '^' '0' 0x90 0x80 'X' CAN ESC \. It compares the bounded terminal's native engine state with the same 1.0 engine fed the raw bytes and fails before the fix with engine-state difference 1. Evidence: /home/claude/.cache/codex-scratch/J339/evidence/c1-dcs-payload-red.log on dev-02.

I will update the limiter to distinguish DCS header bytes from DCS payload bytes, preserve C1 bytes once the DCS header's final byte is reached, and rerun this regression plus the short-control mixture suite.

Access blocker (2026-11-07): this shell cannot resolve infraternal-dev-02-compute01 (SSH reports “Name or service not known”); code-minipc01 is the only linked environment. Link requests for dev-02, the pinned performance VM, and the Mac VM are pending. I have not queued builds or changed remote worktrees. While waiting, python3 scripts/test-build-vt-pinned.py passes both signed offline input/feature/static-shared checks and conditional LZ4-patch checks; python3 scripts/test-vt-scale-rss.py passes; git diff --check is clean. I will recheck build-slot status and continue the paired measurements and requested Linux/macOS gates as soon as access is available.

Finding: the task note pointing to #259 does not match git.kayg.org issue #259, which is a sidebar and Mesh-host rename report. The matching Zig/macOS failure report is #366. Its evidence shows the old 0.15.2 source build resolving vaxis benchmark dependencies from GitHub even when benchmarks were disabled. The 1.0 signed source/deps tarballs and emit_bench guard remove that unused dependency graph through the same scripts/build-vt path on Linux and macOS. I will revalidate the full Mac path after the Mac link is available.

Inventory addendum: the allocation probe also reads stable C data keys GHOSTTY_TERMINAL_DATA_COLS=1 and GHOSTTY_TERMINAL_DATA_ROWS=2; Rust uses key 15 for scrollback rows and key 37 for mode tests. The Rust FFI also maps result values success 0, out-of-memory -1, invalid-value -2, and unsupported -8. The shared-host custom allocator is passed through ghostty_terminal_new as the stable allocator vtable (alloc/resize/remap/free plus four reserved slots). Internal imports still used by the adapters are terminal/c/terminal.zig (Terminal, zigTerminal), terminal/main.zig (Terminal, Screen, PageList.Pin, page.Cell, Style, CharsetSlot G0–G3, Screen.CharsetState, Screen.SavedCursor, modes.Mode/ModeState/ModeTag.fromMode), unicode table/UTF-8 helpers, terminal/lib.zig allocator/calling convention, terminal/mem.zig, page.Page capacity/layout, and the compact-history Cell/Row plus LZ4 HashTable/compress/decompress APIs. The 1.0 C API does not expose the cell metadata, host-wide page-budget accounting, or cold-page compaction hook these paths need.

Continuation progress: control-host SSH access works for compute01, dev-02, the perf VM and the Mac. The control worktree is clean at 8cbefb5639. compute01 has 2/4 slots free and 265 GB free; dev-02 has another job active and one queued, with 88 GB free. The old compute01 J339 checkout is detached and contains unrelated edits, so I will leave it untouched and build from a fresh checkout. Remaining: paired after measurements (throughput, snapshot and RSS), terminal/server and process-per-user tests, verify quick on dev-02, verify fast on compute01, locked Mac build with target cleanup, split commits, then report receipts and final gate output here. Estimate: about 4–6 active hours plus queue time.

Measurement finding: the fresh paired parser/snapshot runs completed on the perf VM under perf-run: throughput 244.91 MB/s (baseline 185.45); snapshot 200x60 plus 256-line tail p50 0.367 ms / p99 0.404 ms / 27,551 bytes (baseline 0.507 / 0.536 / 27,535). Receipts: /home/claude/.cache/codex-scratch/J339/evidence/perf-after-parser.log and perf-after-snapshot.log.

The first after RSS attempt was invalid: I passed the release Rust test harness to vt_scale.py, which expects the production infraternal executable. It exited with error: Unrecognized option: 'fd'; receipt: /home/claude/.cache/codex-scratch/J339/evidence/perf-after-rss-1.log. I will repeat RSS at 1/50/200 sessions with the current static production binary after the final gate has built it.

History update: rebased onto current origin/dev 7dc56b8e89ab8a9ccbfa59de3f1cfa8d776ba23f and pushed the atomic history to libghostty-vt-1.0 at 4da994ce9. The two WIP commits are gone. The source/version migration includes the signed 1.0 source and deps, stable C ABI migration, documented old-patch removals, Zig 0.17/Nix inputs and the dependency SPDX list in its message. Separate commits cover optional VT feature selection, owner-deduplicated RSS accounting, macOS static archive selection, and the DCS C1 payload fix.

The full Mac build is still running under /tmp/mac-bench.lock; the in-lock exit trap removes the worktree target before releasing the lock. Fresh after throughput and snapshot measurements are in the earlier comment. RSS and final Linux gates remain.

Mac verification: the full scripts/macos-build-check passed on the Mac VM under lockf -k /tmp/mac-bench.lock. It verified the pinned Zig 0.17.0 path, built the release executable, ran the portable crate suites and completed the shim session_shell suite (5 passed, 0 failed). Final output: macos-build-check: PASS. Receipt: /Users/claude/.cache/codex-scratch/J339/evidence/macos-build-check-final.log. The in-lock cleanup removed /Users/claude/worktrees/J339-libghostty-vt-1.0-macos/target before releasing the lock; df reported 21 GiB available afterward. This also exercises the #366 cold Mac build path and static adapter link.

Continuation update: final branch head is 4da994ce9a714424c5764352e07f274bf68bcdc6. scripts/verify quick passed on dev-02 inside the Nix shell; receipt: /home/claude/.cache/codex-scratch/J339/evidence/verify-quick-final.log. The Mac build receipt's source tree hash (da932e8c…) matches this final head exactly; macos-build-check: PASS and the Mac worktree target is absent. Its run was under /tmp/mac-bench.lock, covering #366's Zig/macOS path.

Next I am queuing the requested final verify fast on compute01 and will run the remaining final-head terminal and measurement checks. Current queue check: compute01 0/4 free, dev-02's single slot is occupied; free disk is 257G and 82G respectively. The earlier corrected quick setup failures did not modify code or create test evidence.

Finding — the compute01 verify fast workspace test real_binary_rootless_cleanup_survives_sender_disconnect_before_readiness failed once on the busy host. Its output shows cleanup_byte_written=true, sender_disconnected=true, and owned_shell_stopped=true, then the fixture's follow-up terminal.login.revoke returned resource_unavailable. The test/helper are unchanged from the merge base. An isolated run of the same test on this branch passed 1/1 on dev-02; receipt: /home/claude/.cache/codex-scratch/J339/rootless-cleanup-current-isolated.log. The test also failed on a separate isolated origin/dev comparison that is currently queued, so I have not classified the full-gate failure yet.

Correction to the preceding finding comment: the origin/dev comparison is queued and has not run yet. The sentence saying it failed was incorrect; no origin/dev result is claimed.

Compute01 scripts/verify fast on 4da994ce9a714424c5764352e07f274bf68bcdc6 completed with exit 1. The Rust gate summary has VT native fmt FAIL (1) and test FAIL (101); all other rows, including shim process-per-user and static builds, passed.

The Zig formatter named crates/infraternal-shim/native/memory.zig and snapshot.zig. Pinned Zig 0.17.0 zig fmt --check reproduces both; zig fmt rewrites them, including the 0.17 enum conversion spelling. I’m validating and committing that formatter fix.

The single workspace test failure is real_binary_rootless_cleanup_survives_sender_disconnect_before_readiness: the fixture observed cleanup byte written, sender disconnected, and owned shell stopped, then the next revoke got resource_unavailable. The isolated test passed on this branch and the base comparison passed on dev-02.

I’ll rerun verification after the formatter correction and report the full-suite result here.

Follow-up to the format finding: 17c9668e063f6533b7cb614c14aa7d52abe165e1 applies pinned Zig 0.17.0's formatter output to the two files; the corrected VT native fmt row is clean in the running final-head fast gate.

The Mac run on this SHA passed (macos-build-check: PASS, including the 5 session_shell tests) under lockf -k /tmp/mac-bench.lock; the script removed target before lock release. verify quick on dev-02 also exited 0.

Finding: the optional optimized bench-ghostty build first failed at libghostty-vt-sys build.rs:402 with failed to execute zig build: No such file or directory. Evidence: /home/claude/.cache/codex-scratch/J339/evidence/bench-build-final.log. The Nix shell has no zig on PATH, while this branch pins Zig 0.17 under the worktree target and invokes it directly from scripts/build-vt. The dependency supports GHOSTTY_SOURCE_DIR and GHOSTTY_ZIG_SYSTEM_DIR; I’m rerunning the harness with PATH set to the pinned Zig and both overrides pointed at the already signature-verified 1.0.0 release source and deps archives, so the measurement stays offline and on the requested release.

Finding: with the signed 1.0.0 source/deps and pinned Zig 0.17 available, the optional libghostty-vt-sys 0.2.2 harness build reaches Zig but its build script passes --global-cache-dir, which Zig 0.17 rejects (error: unrecognized argument: --global-cache-dir). Evidence: /home/claude/.cache/codex-scratch/J339/evidence/bench-build-final-offline.log. This repo’s 0.17 build path sets ZIG_GLOBAL_CACHE_DIR instead. I’ll adapt only the harness invocation in a scratch Zig shim that translates that flag to the environment variable; no repository source or selected dependency changes.

The VT throughput samples ran on the same perf VM under perf-run (cpus 1–3, 6 GiB). I report medians and ranges because the short parser probe varies between runs.

The real-server local-PTY terminal-links spec passed 1/1. The separate restart spec still has six cases that stop before restart or terminal assertions because the Hosts settings Unlock control is absent after sign-in; the evidence is in my earlier finding comment (real-server-terminal-final-green.log). No UI or fixture change was made for that unrelated setup failure.

J368 finding, P1: dependency SPDX compatibility is fine, but release licence texts are not shipped. At reviewed head, scripts/build-vt extracts the signed source/deps (including root MIT, simdutf MIT/Apache, and the dependency licence files) only under the disposable build target. scripts/package-release copies five executables and SHA256SUMS, and nix/package.nix copies that bundle plus web/SOURCE/VERSION. Neither copies the VT MIT notice, linked dependency licence/copyright texts, or deps/libghostty-vt-third-party.json into the distributed output. Nix's meta.license is metadata, not those required notices. The six SPDX expressions in the signed manifest are AGPL-3.0-only compatible (aro is build-only), but the manifest itself is not a substitute for licence texts. Please include the linked libraries' applicable notices in the release/Nix output, with a packaging assertion. I am preserving a release-fixture listing as additional evidence before the final verdict.

J368 independent perf reproduction finished: five alternating baseline/branch pairs per probe on perf VM, each under perf-run's exclusive lock/cpus 1–3/6 GiB, announced on #260. Baseline harness is J339's preserved shipped-engine artifact; shim production code/build-vt did not change between that dev baseline (6ffe37e) and frozen origin/dev except the unused comparison example.

Throughput MB/s, baseline: 174.69, 196.56, 196.69, 170.28, 191.76; branch: 227.75, 229.96, 233.12, 214.19, 230.73. Medians 191.76 → 229.96 (+19.9%). Every branch sample beats every baseline sample. This reproduces a real improvement; the exact +15.6% is sample-dependent.

Snapshot median-of-run p50: 0.509 → 0.358 ms (-29.7%); median-of-run p99: 0.535 → 0.377 ms (-29.5%). Branch's first p99 was 0.456 ms; all raw samples retained rather than discarded. Output 27,535 → 27,551 bytes.

Receipts: perf VM /home/claude/.cache/codex-scratch/j368/{1..5}-{baseline,branch}-{throughput,budgets}.log, accompanying per-run before/after machine snapshots; summary.json and binary-hashes.txt in the same directory. Source/harness feature equivalence checked against the reviewed diff. No performance assertions were run on build VMs.

J368 Mac evidence: the independent locked scripts/macos-build-check passed, including session_shell 5/5. I additionally ran the complete shim default-feature lib suite under that lock: 109 passed, 1 failed, 14 ignored.

This is an unclassified failure pending an isolated branch/dev comparison, not yet a branch regression claim. The retry will copy the child probe receipts out of target before its in-lock cleanup.

Separate measurement caveat under investigation: the preserved perf VM J339/bin/infraternal-baseline is 27,773,808 bytes, whereas the cited baseline static-build receipt says 27,662,256. Final preserved binary matches 28,237,080. I will distinguish the supplied historical size delta from my same-artifact section comparison rather than conflate these binaries.

J368 finding, P2: the section-splitting patch was dropped without equivalent upstream behavior. scripts/build-vt:176 says section layout is upstream, but signed 1.0's build graph does not set link_function_sections or link_data_sections. With the same signed source, pinned Zig, ReleaseFast x86_64-musl, -all feature set, snapshot adapter and C lifecycle/painter caller, restoring just those two flags shrinks the stripped linked probe from 1,346,096 to 1,131,696 bytes: 214,400 bytes saved. Both executables run successfully. This is a linked native probe delta, not a promised full Rust product delta.

Restore the section flags, or give a measured reason to retain their absence, and correct the upstream-equivalence comment. Without section splitting, linker GC retains unrelated exports sharing the native code section, including APIs the product does not call. All optional VT features are already disabled; toggling graphics/search/selection/input encoding off again saves zero. Logging and combined section/logging probes are still running.

J368 independent review: REQUEST CHANGES.

Reviewed libghostty-vt-1.0 at 17c9668e063f6533b7cb614c14aa7d52abe165e1 against frozen origin/dev f6f62a8759897a47f24031dd743bdedd062334f7. No merge or deployment; only the review reproducer branch was pushed.

P1: distribute the linked engine's licence notices. scripts/package-release emits five executables and SHA256SUMS, with no readable upstream copyright/permission notice. nix/package.nix also does not install these notices; Nix licence metadata is insufficient. The signed source/deps retain licence files only in disposable build inputs. The packaging reproducer fails with AssertionError: release omits the linked libghostty-vt MIT copyright and permission notice. Fix the binary and Nix distributions to carry the engine MIT notice and applicable linked-dependency notices, including Unicode text where required. This packaging gap may predate the upgrade, but it fails this task's explicit shipping requirement. Red test: review-j368 commit 76eccdfadbb928330d5884bb2e0b750435f1c1cb, scripts/test-vt-release-notices.py --binary <real-static-ELF>. Receipt attached to comment 86523.

The SPDX inventory itself is compatible with AGPL-3.0-only: aro (build-only) MIT AND Unicode-3.0; highway Apache-2.0 OR BSD-3-Clause; simdutf Apache-2.0 OR MIT; translate_c MIT; uucode MIT AND Unicode-3.0; wuffs Apache-2.0 OR MIT. Preserve the notices for the licence alternatives actually distributed. The core engine is MIT.

P2: restore or justify the dropped section/logging size controls. scripts/build-vt:176 incorrectly says section layout is handled upstream. Signed 1.0 does not set link_function_sections/link_data_sections. A controlled signed-release, pinned-Zig, ReleaseFast x86_64-musl C lifecycle/getter/painter probe, linked with GC and stripped, produced:

Native probe variant Bytes Saved versus minimal
Current minimal feature set 1,346,096 0
Function and data sections 1,131,696 214,400
Callback-free logging 1,196,288 149,808
Both 992,240 353,856

All four linked executables ran successfully; J368_SIZE_EXIT=0. The old section flags permit GC of unused exports and their dependencies. A null log callback preserves runtime silence but still leaves formatting code linked. These dropped patches are therefore not equivalent for size. Restore the flags and reconsider the logger patch, or document a measured reason for retaining the extra bytes. The probe is a controlled native comparison, not a full Rust product size saving; the two individual savings overlap. Receipt: compute01 /home/claude/.cache/codex-scratch/j368/evidence/size.log, per-variant sections/symbols under evidence/size/; measurement driver and raw log attached below.

Further optional feature savings from the current shipping configuration: graphics 0, search 0, selection 0, input encoding 0. All are already disabled by -Dvt-features=-all; render-state and the other optional VT APIs are also off. Input encoding is enabled only by the explicit native mouse test feature. These zeros mean no additional saving from disabling them again, not that those features would be free if enabled.

P3: reconcile the size baseline artifacts. The reported receipts are 27,662,256 → 28,237,080 bytes on x86 (+574,824, 2.1%) and 24,905,984 → 25,389,272 on aarch64 (+483,288, 1.9%). However, the preserved J339/bin/infraternal-baseline supplied with the perf artifacts is 27,773,808 bytes, 111,552 larger than that baseline receipt. The preserved final executable matches 28,237,080. Their direct delta is 463,272: .text +299,855 and .rodata +122,624 dominate it, with unwind tables and relocation data also growing. Label the historical baseline distinctly and retain source SHA/build recipe/binary hash together; do not attribute the whole quoted +575 KB to the engine from mismatched artifacts. I have not rebuilt a full frozen-dev static binary, so exact whole-product attribution remains unverified. The controlled native probe above demonstrates 353,856 avoidable bytes in that probe independently of this provenance gap. Receipts attached: preserved-static-sizes.txt and full-static-sections.txt.

Adapter and correctness. No demonstrated branch-specific correctness defect. Stable C lifecycle, scrollback-byte option and history/mode getters match the release headers/implementation; the painter's internal state access is covered by the fidelity suites. The allocator vtable's reserved slots are retained. The removed resize rollback patch is covered by upstream cleanup; allocation-refusal probes pass on Linux. The retained PPU allocator, page-pool, preheat, geometry, bounded history and LZ4 changes have rationale comments. Compact-history still needs its explicit internal export, which the branch supplies; it is not assumed to exist in the stable API. Orphaned spacer heads and charset-shifted wide text now replay faithfully rather than reject those fixtures. Semantic prompt metadata that changes replay remains checked; the omitted aggregate seen bit is not itself observable for the accepted prompt-free trimmed history. This is review evidence, not a proof for every terminal stream.

After exact launcher preflights, Linux runs used build-slot, nice and Nix:

  • dev-02: PPU shim lib 226 passed, 0 failed, 20 ignored, including user_screen_pool_resize; compact-history 5 passed, 0 failed, 3 ignored; session_retention 1 passed.
  • compute01: PPU shim lib 226 passed, 0 failed, 20 ignored; compact-history 5 passed, 0 failed, 3 ignored; session_retention 1 passed. Both logs end J368_TEST_EXIT=0.
  • macOS: scripts/macos-build-check passed under lockf -k /tmp/mac-bench.lock, including session_shell 5/5. The additional complete default-feature shim suite had 109 passed, 1 failed, 14 ignored. Its resize-refusal PTY continuation failure reproduces in isolated runs on both reviewed head and frozen dev, at the same child probe (session_resize.rs:210, PTY continuation did not finish). It is pre-existing, not demonstrated as an upgrade regression. Target removed before lock release. Attached comparison receipts: comment 86537.

Linux receipts: each VM /home/claude/.cache/codex-scratch/j368/evidence/linux-tests.log. Mac receipt /Users/claude/.cache/codex-scratch/j368/evidence/mac.log, plus mac-resize-{branch,dev}.log and preserved child-probe logs. All three build VM targets were removed; all owned test/build/measurement runs have finished. Raw evidence remains outside the targets.

Performance. Five alternating shipped-engine baseline/branch pairs per probe on the perf VM, each under perf-run's exclusive lock, CPUs 1–3 and 6 GiB cap; claim announced on #260. Throughput MB/s baseline: 174.69, 196.56, 196.69, 170.28, 191.76; branch: 227.75, 229.96, 233.12, 214.19, 230.73. Median 191.76 → 229.96, +19.9%. Every branch sample exceeds every baseline sample: the improvement is real; +15.6% is sample-dependent. Median-of-run snapshot p50 0.509 → 0.358 ms (-29.7%); p99 0.535 → 0.377 ms (-29.5%). All samples retained, including branch first-run p99 0.456 ms. Output 27,535 → 27,551 bytes. Raw runs, binary hashes and before/after machine receipts persist on perf VM under /home/claude/.cache/codex-scratch/j368/; summary attached to comment 86526. These use J339's preserved executable artifacts, whose production shim/build inputs were checked against frozen dev, rather than newly rebuilding a second benchmark harness. RSS was not independently rerun.

Restart spec. The first locked-authority case fails identically on a production build of frozen dev after successful sign-in: missing Hosts settings Unlock at restart-fixture.ts:130. The fixture does not open the lazily loaded Hosts settings body before querying it. This predates the upgrade; the six reported setup stops are not six independent VT failures. I stopped the baseline run after the first shared setup failure. Production-build screenshot and log attached to comment 86537. No deployed server was changed.

Author gate, read rather than rerun. Reviewer exception in BRIEF-COMMON prohibits rerunning quick/fast. I read /home/claude/.cache/codex-scratch/J339/evidence/verify-fast-final-17c9668.log; the Rust gate table below is verbatim. The receipt also ends with protocol tests 50 pass, 0 fail, 77253 expect() calls, Ran 50 tests across 13 files. [6.83s]. The new review test deliberately remains red; it is not represented as a green author gate.

verdict: REQUEST CHANGES
head: 17c9668e06

J368 independent review: **REQUEST CHANGES**. Reviewed `libghostty-vt-1.0` at `17c9668e063f6533b7cb614c14aa7d52abe165e1` against frozen origin/dev `f6f62a8759897a47f24031dd743bdedd062334f7`. No merge or deployment; only the review reproducer branch was pushed. **P1: distribute the linked engine's licence notices.** `scripts/package-release` emits five executables and SHA256SUMS, with no readable upstream copyright/permission notice. `nix/package.nix` also does not install these notices; Nix licence metadata is insufficient. The signed source/deps retain licence files only in disposable build inputs. The packaging reproducer fails with `AssertionError: release omits the linked libghostty-vt MIT copyright and permission notice`. Fix the binary and Nix distributions to carry the engine MIT notice and applicable linked-dependency notices, including Unicode text where required. This packaging gap may predate the upgrade, but it fails this task's explicit shipping requirement. Red test: `review-j368` commit `76eccdfadbb928330d5884bb2e0b750435f1c1cb`, `scripts/test-vt-release-notices.py --binary <real-static-ELF>`. Receipt attached to comment 86523. The SPDX inventory itself is compatible with AGPL-3.0-only: aro (build-only) MIT AND Unicode-3.0; highway Apache-2.0 OR BSD-3-Clause; simdutf Apache-2.0 OR MIT; translate_c MIT; uucode MIT AND Unicode-3.0; wuffs Apache-2.0 OR MIT. Preserve the notices for the licence alternatives actually distributed. The core engine is MIT. **P2: restore or justify the dropped section/logging size controls.** `scripts/build-vt:176` incorrectly says section layout is handled upstream. Signed 1.0 does not set `link_function_sections`/`link_data_sections`. A controlled signed-release, pinned-Zig, ReleaseFast x86_64-musl C lifecycle/getter/painter probe, linked with GC and stripped, produced: | Native probe variant | Bytes | Saved versus minimal | | --- | ---: | ---: | | Current minimal feature set | 1,346,096 | 0 | | Function and data sections | 1,131,696 | 214,400 | | Callback-free logging | 1,196,288 | 149,808 | | Both | 992,240 | 353,856 | All four linked executables ran successfully; `J368_SIZE_EXIT=0`. The old section flags permit GC of unused exports and their dependencies. A null log callback preserves runtime silence but still leaves formatting code linked. These dropped patches are therefore not equivalent for size. Restore the flags and reconsider the logger patch, or document a measured reason for retaining the extra bytes. The probe is a controlled native comparison, not a full Rust product size saving; the two individual savings overlap. Receipt: compute01 `/home/claude/.cache/codex-scratch/j368/evidence/size.log`, per-variant sections/symbols under `evidence/size/`; measurement driver and raw log attached below. Further optional feature savings from the current shipping configuration: graphics **0**, search **0**, selection **0**, input encoding **0**. All are already disabled by `-Dvt-features=-all`; render-state and the other optional VT APIs are also off. Input encoding is enabled only by the explicit native mouse test feature. These zeros mean no additional saving from disabling them again, not that those features would be free if enabled. **P3: reconcile the size baseline artifacts.** The reported receipts are 27,662,256 → 28,237,080 bytes on x86 (+574,824, 2.1%) and 24,905,984 → 25,389,272 on aarch64 (+483,288, 1.9%). However, the preserved `J339/bin/infraternal-baseline` supplied with the perf artifacts is 27,773,808 bytes, 111,552 larger than that baseline receipt. The preserved final executable matches 28,237,080. Their direct delta is 463,272: `.text` +299,855 and `.rodata` +122,624 dominate it, with unwind tables and relocation data also growing. Label the historical baseline distinctly and retain source SHA/build recipe/binary hash together; do not attribute the whole quoted +575 KB to the engine from mismatched artifacts. I have not rebuilt a full frozen-dev static binary, so exact whole-product attribution remains unverified. The controlled native probe above demonstrates 353,856 avoidable bytes in that probe independently of this provenance gap. Receipts attached: `preserved-static-sizes.txt` and `full-static-sections.txt`. **Adapter and correctness.** No demonstrated branch-specific correctness defect. Stable C lifecycle, scrollback-byte option and history/mode getters match the release headers/implementation; the painter's internal state access is covered by the fidelity suites. The allocator vtable's reserved slots are retained. The removed resize rollback patch is covered by upstream cleanup; allocation-refusal probes pass on Linux. The retained PPU allocator, page-pool, preheat, geometry, bounded history and LZ4 changes have rationale comments. Compact-history still needs its explicit internal export, which the branch supplies; it is not assumed to exist in the stable API. Orphaned spacer heads and charset-shifted wide text now replay faithfully rather than reject those fixtures. Semantic prompt metadata that changes replay remains checked; the omitted aggregate `seen` bit is not itself observable for the accepted prompt-free trimmed history. This is review evidence, not a proof for every terminal stream. After exact launcher preflights, Linux runs used build-slot, nice and Nix: - dev-02: PPU shim lib 226 passed, 0 failed, 20 ignored, including `user_screen_pool_resize`; compact-history 5 passed, 0 failed, 3 ignored; session_retention 1 passed. - compute01: PPU shim lib 226 passed, 0 failed, 20 ignored; compact-history 5 passed, 0 failed, 3 ignored; session_retention 1 passed. Both logs end `J368_TEST_EXIT=0`. - macOS: `scripts/macos-build-check` passed under `lockf -k /tmp/mac-bench.lock`, including session_shell 5/5. The additional complete default-feature shim suite had 109 passed, 1 failed, 14 ignored. Its resize-refusal PTY continuation failure reproduces in isolated runs on both reviewed head and frozen dev, at the same child probe (`session_resize.rs:210`, `PTY continuation did not finish`). It is pre-existing, not demonstrated as an upgrade regression. Target removed before lock release. Attached comparison receipts: comment 86537. Linux receipts: each VM `/home/claude/.cache/codex-scratch/j368/evidence/linux-tests.log`. Mac receipt `/Users/claude/.cache/codex-scratch/j368/evidence/mac.log`, plus `mac-resize-{branch,dev}.log` and preserved child-probe logs. All three build VM targets were removed; all owned test/build/measurement runs have finished. Raw evidence remains outside the targets. **Performance.** Five alternating shipped-engine baseline/branch pairs per probe on the perf VM, each under perf-run's exclusive lock, CPUs 1–3 and 6 GiB cap; claim announced on #260. Throughput MB/s baseline: 174.69, 196.56, 196.69, 170.28, 191.76; branch: 227.75, 229.96, 233.12, 214.19, 230.73. Median 191.76 → 229.96, **+19.9%**. Every branch sample exceeds every baseline sample: the improvement is real; +15.6% is sample-dependent. Median-of-run snapshot p50 0.509 → 0.358 ms (-29.7%); p99 0.535 → 0.377 ms (-29.5%). All samples retained, including branch first-run p99 0.456 ms. Output 27,535 → 27,551 bytes. Raw runs, binary hashes and before/after machine receipts persist on perf VM under `/home/claude/.cache/codex-scratch/j368/`; summary attached to comment 86526. These use J339's preserved executable artifacts, whose production shim/build inputs were checked against frozen dev, rather than newly rebuilding a second benchmark harness. RSS was not independently rerun. **Restart spec.** The first locked-authority case fails identically on a production build of frozen dev after successful sign-in: missing Hosts settings Unlock at `restart-fixture.ts:130`. The fixture does not open the lazily loaded Hosts settings body before querying it. This predates the upgrade; the six reported setup stops are not six independent VT failures. I stopped the baseline run after the first shared setup failure. Production-build screenshot and log attached to comment 86537.

J368 P1 reproduced before changes on compute01 using the static x86_64 artifact /home/claude/.cache/codex-scratch/j368/infraternal-final (28,237,080 bytes): nix develop /home/claude/worktrees/J339-libghostty-vt-1.0-resume -c python3 scripts/test-vt-release-notices.py --binary <artifact> exits 1 with AssertionError: release omits the linked libghostty-vt MIT copyright and permission notice. Its staged bundle contains only SHA256SUMS and the five executables. Nix copies that bundle, so its output also lacks notices.

I traced the missing files to the signed 1.0.0 source/deps being extracted under the disposable build cache, with no copy into either distribution. I will ship the engine MIT notice and the bundled dependencies' notices in licenses/libghostty-vt/, preserve the SPDX alternatives for Highway, simdutf, and Wuffs, include the uucode MIT and Unicode-3.0 texts, and expose the same directory from the Nix output. The build-only aro package is not a linked runtime dependency.

P1 fix committed as 665f1482a and pushed to libghostty-vt-1.0. scripts/package-release now ships the MIT and dependency texts under licenses/libghostty-vt/, includes them in SHA256SUMS, and the Nix output exposes the same tree at share/licenses/infraternal. The J368 scripts/test-vt-release-notices.py --binary <static-ELF> passes; scripts/test-package-release.py also passes with the same release bundle and checksum verification.

J368 P2 root cause and evidence: the pre-1.0 build patched src/build/GhosttyLibVt.zig to set lib.link_function_sections = true and lib.link_data_sections = true. The 1.0 GhosttyLibVt.zig static library block has neither setting, and scripts/build-vt now incorrectly says section layout is upstream. The prior logger override was also removed: session images no longer substitute a no-op std.log sink or remove the unused log setter/stderr exports.

J368's pinned native ReleaseFast x86_64 probe measured 1,346,096 bytes minimal; 1,131,696 with function/data sections (−214,400); 1,196,288 with callback-free logging (−149,808); and 992,240 with both (−353,856, with overlap). The four linked executables all ran successfully. I will restore sectioning for the static engine and restore callback-free logging only for the private session-image feature, which has no C logging callback consumer, then remeasure the shipped binaries and spot-check throughput.

P2 fix committed as 5f96a8e61. The pinned 1.0 static build now emits function/data sections for final-link GC. Only private session-image builds replace the runtime-switchable logger with a no-op and omit the two unconsumed logging callback exports; ordinary builds retain upstream logging behavior. The stale scripts/build-vt comment is corrected.

Focused recipe test on dev-02 passed at the same source tree:
nix develop /home/claude/worktrees/j339-libghostty-vt-1.0-dev02 -c python3 scripts/test-build-vt-pinned.py
PASS: signed offline inputs, pinned Zig, feature selection and static/shared artifacts
PASS: bounded LZ4 safety patch remains conditional

J368's native probe measured 214,400 bytes saved by sectioning and 149,808 by callback-free logging; the combined result was 353,856 bytes with overlapping reachability. The final product size and throughput spot-check are still pending.

P2 performance spot-check and size trade-off, measured on the pinned perf VM with perf-run (CPUs 1–3, 6 GiB; machine reports no competing process above 5% CPU and zero steal during each run).

The P2 x86_64 release test binary hash is c5d2c56ce417d88953ffbe8a89f814223dbc9b9a78b454dc4fa1071f153db69e; the pre-P2 17c9668e binary hash is b34f6e03c6736c070d6dc5cc5c3791b3b5016efbbf4bb5355f1154e92da1b669.

Five alternating parser samples per build:

  • pre-P2: 206.11, 202.12, 200.25, 200.45, 231.96 MB/s; median 202.12.
  • P2: 206.92, 201.63, 191.77, 201.74, 218.15 MB/s; median 201.74 (-0.19%).

Ten alternating snapshot samples per build, reversing run order for the second five:

  • p50 median: 0.3615 ms pre-P2 → 0.3735 ms P2 (+0.012 ms, 3.3%).
  • p99 median: 0.3865 ms pre-P2 → 0.3970 ms P2 (+0.0105 ms, 2.7%).
  • Snapshot output remained 27,551 bytes; all p99 samples are below 0.5 ms, against the test's 2 ms limit.

The restored final-link GC controls reduce the matched static product by 356,064 bytes x86_64 and 337,616 bytes aarch64. The direct paired throughput median is effectively unchanged; the measured snapshot increase is about 10–12 microseconds and remains well within its bound.

J339 review fixes complete. Branch libghostty-vt-1.0 is at 267d2c809d0aaaa80671c4aa664ce437ba64e1c5; the origin branch matches. No merge or deployment was performed.

Atomic commits:

  • 665f1482a ships the libghostty-vt MIT notice and linked dependency notices in release and Nix outputs. The notice test passes. The SPDX set is libghostty-vt MIT; Highway Apache-2.0 OR BSD-3-Clause; simdutf Apache-2.0 OR MIT; translate_c MIT; uucode MIT AND Unicode-3.0; Wuffs Apache-2.0 OR MIT; aro (build-only) MIT AND Unicode-3.0.
  • 5f96a8e61 restores function/data sections for final-link GC and callback-free logging for the private session-image feature, and corrects the stale build comment.
  • 267d2c809 records reproducible static-size provenance and hashes for the matched builds.

Matched dev-02 static build sizes (same Zig 0.17.0, scripts/static-cargo, Cargo.lock and flake.lock):

Target Pre-P2 P2 Change
x86_64-unknown-linux-musl 28,240,792 B 27,884,728 B −356,064 B (−1.26%)
aarch64-unknown-linux-musl 25,388,760 B 25,051,144 B −337,616 B (−1.33%)

This matched rebuild resolves the earlier baseline artifact mismatch; the old 27,662,256-byte x86 artifact is not used for attribution. In J368's controlled native probe, sectioning saved 214,400 B and callback-free logging saved 149,808 B; together they saved 353,856 B with overlap. All four probe executables ran successfully.

Perf-VM review-fix spot-check, five alternating throughput samples and ten alternating snapshot samples per build:

Measurement Pre-P2 P2 Change
Parser throughput median 202.12 MB/s 201.74 MB/s −0.19%
Snapshot p50 median 0.3615 ms 0.3735 ms +0.012 ms (+3.3%)
Snapshot p99 median 0.3865 ms 0.3970 ms +0.0105 ms (+2.7%)
Snapshot output 27,551 B 27,551 B unchanged

All P2 p99 samples remained below 0.5 ms against the 2 ms test bound. The earlier full upgrade comparison recorded 1/50/200-session RSS growth of 27,120 / 27,119.8 / 27,119.5 KiB before and 25,488 / 25,483.4 / 25,483.5 KiB after (about −6% at each point); those session-memory measurements were not rerun for the link-control review fix.

Verification:

  • scripts/test-vt-release-notices.py passed against the P2 x86_64 static artifact.
  • verify quick on dev-02: VERIFY_QUICK_EXIT=0; target removed.
  • Mac scripts/macos-build-check passed under lockf -k /tmp/mac-bench.lock, Zig 0.17.0, including session_shell 5/5; target removed before the lock was released.
  • verify fast on compute01: VERIFY_FAST_EXIT=0; target removed. Its output:

J390 P1: the release-publication path still drops the notices. scripts/package-release now stages them, but scripts/release/build:33 overwrites SHA256SUMS with ten fixed root names. scripts/release/publish:12,35 uploads only its fixed files list (plus component archives), so no licenses/libghostty-vt/* object reaches recipients. scripts/release/common:51 rejects such manifest paths, and the signer has its own fixed object inventory. The lower-level packager test cannot cover this path.

Reproduced on scratch merge 1b05ae8497 (reviewed head 267d2c809 + dev 9965911c8) on compute01, with Nix and the existing release-channel fixture modified only to feed real notice files from package-release into the real release/build script. The notice exists in the resulting bundle, but the manifest omits it. Command: nix develop . -c python3 ~/.cache/codex-scratch/j390/evidence/release-pipeline-red.py ReleaseScripts.test_version_grammar_and_explicit_build_channel. Exit 1: AssertionError: 'licenses/libghostty-vt/libghostty-vt-MIT.txt' not found ... : release/build dropped VT notices from SHA256SUMS.

Reproducer and full output: compute01 /home/claude/.cache/codex-scratch/j390/evidence/release-pipeline-red.{py,log}. No publication or deployment occurred. Fix the complete build/sign/publish/download contract to distribute and verify the notices, preserving bounded path allowlists, and add a publication-path regression test. This leaves J368's P1 unresolved for published releases; the local packager and Nix path are separate checks still underway.

J390 licence verification update: all 11 distributed .txt files exactly match files in the checksum/signature-verified 1.0 source/dependency extraction (license-check.log, LICENSE_EXACT_MATCH=PASS). SPDX inventory remains permissive and AGPL-3.0-only compatible: engine MIT; Highway Apache-2.0 OR BSD-3-Clause; simdutf and Wuffs Apache-2.0 OR MIT; translate_c MIT; uucode MIT AND Unicode-3.0; build-only aro MIT AND Unicode-3.0. No additional top-level dependency NOTICE files were found.

The actual package-release --built staging succeeds, every licence is in SHA256SUMS and passes strict checksum verification, and scripts/release/deploy.archive carries the notices in its transport tarball (18 members). Executing the installPhase evaluated from .#packages.x86_64-linux.default.installPhase against that real bundle exposes identical bytes at share/licenses/infraternal/libghostty-vt/*.

P1 from comment 86985 remains: signed public publication bypasses these working local bundle/install paths. Precision correction: the Worker signer is root-path-only, not a fixed filename inventory: apps/release-signer/src/index.js:121 explicitly skips every name containing /, so it would omit licenses/... even if the publisher uploaded those objects. The fix must cover that boundary too. No external publishing or deployment has been performed.

J390's minimal P1 regression is committed locally as 1f008bfb90873814eca70bfbbd1b7ae30630da52 on review-j390, with the patch attached to comment 86985 (p1-regression.zip). It extends the existing release-channel fixture rather than adding a separate harness. Replayed on compute01 against the unchanged scratch merge, it fails with all 12 licenses/libghostty-vt/* paths missing from final SHA256SUMS (release-notices-regression.log, exit 1). No review branch was pushed. Full quick/fast runs remain on unmodified scratch merge 1b05ae84971f71cab54f435264bbb9b67355c460, so the intentionally red review test does not contaminate the author's gate result.

J390 P2/P3 cross-check: independently hashed and sized the preserved matched pre-P2 and P2 artifacts on dev-02. All four binary hashes exactly match docs/verification/libghostty-vt-1.0-size-provenance.md. The source commits' Cargo.lock and flake.lock hashes also match each other. Verified recorded static reductions: x86_64 28,240,792 → 27,884,728 bytes (-356,064); aarch64 25,388,760 → 25,051,144 bytes (-337,616). Raw artifact receipt: compute01 /home/claude/.cache/codex-scratch/j390/evidence/p2-artifact-check.txt (original files remain on dev-02 under J339-review-fixes/evidence/). This confirms that the provenance record identifies real matching files; it is not presented as J390's fresh build or as the current-dev comparison, both still pending behind the required gate queue.

J390: fresh x86_64 static release build on the scratch merge finished. The gate reports:

PT_INTERP: absent; size: 28225752 bytes; baseline 22418256; delta +5807496 bytes (report only, D243 amended 2026-11-01)

The x86 key-memory check passed. aarch64 is compiling; fast has no final result yet. This recorded gate baseline is not the current-dev comparison. That comparison will rebuild frozen dev 9965911c8 in the same isolated checkout path after preserving branch outputs and finishing branch checks, then restore review-j390; exact source-SHA guards and a restore trap are in the scratch driver. This keeps source-path remap flags and unchanged dependency artifacts matched, avoiding an unnecessary rebuild caused by a second checkout path. Both ordinary daemon and private session executables are included in the size capture.

Evidence: /home/claude/.cache/codex-scratch/j390/evidence/fast.log, matched-build.sh, remaining.sh. P1 publication finding remains unchanged. No push, shared-branch merge, or deployment.

J390 measurement-plan correction before any baseline build: retain the separate frozen dev checkout (/home/claude/worktrees/j390-dev) rather than the same-path checkout proposed in 87631. The Zig pin also changes native C compiler inputs, and Cargo's cached build-script outputs must not obscure that distinction. Distinct checkout/remap/compiler paths force independent fingerprints for the static baseline, at the cost of rebuilding dependencies. Both checkouts still use the one physical J390 target directory. No baseline measurements or source checkout switches were made under the superseded approach. Exact SHA guards remain enabled.

J390 receipt-label correction to 87595: quick's stand-alone default shim lib suite was 115 passed / 0 failed / 14 ignored. Fast's workspace shim lib suite was 158 passed / 0 failed / 15 ignored, with Cargo workspace feature unification (including CLI/session features). The explicit process-per-user lib suite was 226 passed / 0 failed / 20 ignored. These are all passing receipts, but 158 should not be labeled the stand-alone default configuration. Full logs retain the exact commands/binaries. The forthcoming matched parser executables explicitly use --features session-image, matching the shipping executable engine configuration on both source revisions; the ordinary logger boundary is checked separately in compiled archives.

J390 follow-up: explicit release session-image lib tests passed 115 / 0 failed / 14 ignored, SESSION_IMAGE_EXIT=0.

Two initial review harness invocations were unsuitable and their failures are retained:

  • test-lib-vt in ReleaseSafe: upstream PageList tests require build_options.slow_runtime_safety (compile-time assertion), while the Zig-only module also reaches our C-only adapter exports with Zig ABI types. No shipping build failed. Upstream build.zig:489–496 explicitly documents that test-lib-vt-build -Demit-test-exe=true emits the C test binary containing every test from the Zig module plus the C tests. That documented superset is scheduled in Debug mode, with its result still pending.
  • I initially selected user_host from infraternal-shim; it belongs to infraternal. The corrected process-per-user integration command is scheduled with --no-default-features, since it exercises the standalone research-host command.

Evidence: /home/claude/.cache/codex-scratch/j390/evidence/{vt-suite,session-image,user-host}.log; corrected receipts will be vt-suite-c.log and user-host-corrected.log. Initial failures are not being counted as passing tests or attributed to #421. No product source changes were made.

J390 P2: the explicit native mouse continuation test was not fully ported to the 1.0 C API. On the clean scratch merge 1b05ae849 (reviewed 267d2c809), nix develop . -c cargo test --locked -p infraternal-shim --features vt-test-input --test mouse fails with exit 101. tests/native/mouse_probe.c:12,14 still calls ghostty_mouse_encoder_setopt_from_terminal and ghostty_mouse_encoder_setopt; neither is declared by the signed 1.0 headers, so the C probe cannot compile and never checks snapshot mouse continuations. This is repository test code, not the review harness. The main fast gate did not exercise this explicit feature.

Evidence: compute01 /home/claude/.cache/codex-scratch/j390/evidence/mouse.log and /home/claude/.cache/codex-scratch/infraternal-shim-tests/evidence/mouse-2545863/{mouse-build,stderr}.log. Compiler output: error: call to undeclared function 'ghostty_mouse_encoder_setopt_from_terminal' and the same error for ghostty_mouse_encoder_setopt. Port the remaining encoder calls and retain the exact-library probe selection. No runtime mouse regression is claimed from this compile failure.

J390 real branch-server smoke finished on compute01 using the retained x86 static binary and freshly built production tracer. A fresh private server/browser/passkey and real PTY were used, with cleanup in finally; no deployment or shared authenticator state was used. Vim saved exactly j390 界🙂 é\n, htop entered/exited its full-screen UI, and wide-char output reached the rendered terminal. Screenshots are attached. OSC 52 bytes were observed through the bridge, but the browser clipboard stayed unchanged despite granted permissions; this is a failed clipboard check, even though the harness process exits 0 after recording it. Baseline dev smoke remains pending before attribution.

J390 P3: the repaired artifact hashes match, but the size-control attribution still needs one correction. docs/verification/libghostty-vt-1.0-size-provenance.md:82–85 says the private session-image logger is checked separately and “does not change the ordinary product configuration.” Both pre-P2 17c9668e and P2 5f96a8e61 have crates/infraternal/Cargo.toml:22 unconditionally enabling infraternal-shim features ["session-image", "cli"]; infraternal-session enables session-image too. The stated static-cargo ... --package infraternal recipe therefore includes the logger change. Its -356,064 / -337,616-byte result is a combined P2 product delta, not an isolated sectioning measurement.

Correct the prose to label the combined controls, keeping J368's separate native-probe measurements distinct. The numerical sizes/hashes themselves are verified; no new isolated product measurement is claimed or required for that labeling fix. Source evidence: git show 17c9668e:crates/infraternal/Cargo.toml and git show 5f96a8e61:crates/infraternal/Cargo.toml contain the same feature selection. J390 parser executables already explicitly use session-image on both revisions, matching the shipping executable configuration.

J390 upstream VT suite is still running (beyond 2,700 / 3,671 cases). It has one observed failure so far: terminal.stream_terminal.test.full reset, stream_terminal.zig:3361, where expect(t.glyph_glossary.contains(0xE0A0)) runs BEFORE the RIS/reset command. Our tested -Dvt-features=-all configuration disables glyph registration, so that setup precondition cannot hold. The immediately adjacent glyph test guards if (comptime !build_options.glyph_protocol) return error.SkipZigTest; the full-reset fixture does not. This is not being counted as a passing suite or attributed to #421, and it does not demonstrate a reset runtime regression. Final counts remain pending.

J390 correction: my progress-count regex missed multiline Zig failures (expected ... on the test-name line, followed by FAIL on the next line). The earlier “one observed failure” count in 87779 and interim progress text is incorrect. The unedited vt-suite-c.log currently contains 221 failures: the glyph setup precondition plus C API cases for optional selection/search/input/formatter/render/color/cell facilities disabled by the test invocation's -Dvt-features=-all. The default-feature upstream C fixtures are not a passing oracle under that configuration. Full failure names are retained in compute01 /home/claude/.cache/codex-scratch/j390/evidence/vt-failure-summary.txt; raw output remains unchanged.

The run is still in the large hyperlink-map snapshot stress case. A focused enabled-feature recheck (terminal.c. plus full reset filters, omitting -Dvt-features=-all) is scheduled next before the dev build, so the feature-mismatch explanation can be tested without changing the shipping configuration or repeating the large internal fuzz/stress cases. That diagnostic has not run or passed yet. The repository-native mouse test failure in 87753 remains separate: it cannot compile due to removed C API names. P1/P3 findings are unchanged.

J390 enabled-feature C API recheck PASSED: All 549 tests passed, VT_ENABLED_DELTA_BINARY_EXIT=0, VT_ENABLED_DELTA_EXIT=0; no logged-error or leak summary. Comparing test names shows all 221 failures from the -all run pass in this enabled-feature diagnostic (vt-delta-coverage.json: covered_failures=221, uncovered_failures=[]). The raw minimal-feature run remains red and unchanged; its feature-unaware upstream fixtures are now accounted for rather than presented as engine regressions.

The corrected private process-per-user integration initially hit an environment-dependent fixture path of exactly 108 bytes with seven-digit PIDs (path must be shorter than SUN_LEN). Running its already-compiled binary with a fresh short HOME passed 2/2, USER_HOST_SHORT_HOME_EXIT=0, and the temporary HOME was removed. Logs: user-host-corrected.log (red), user-host-short-home.log (green).

Compiled native archive inspection PASSED (ARCHIVE_CHECK_EXIT=0): all completed variants emit function and data sections; ordinary archives retain ghostty_sys_set and ghostty_sys_log_stderr; only private-image archives omit them and contain the no-op source. Receipt archive-check.log. Fresh frozen-dev builds are now running in the existing reservation. Evidence root remains compute01 /home/claude/.cache/codex-scratch/j390/evidence/.

J390 progress: the initial frozen-dev (9965911c8) static build failed in native C dependency compilation while parsing Zig .o.d files. Both source pins remain unchanged: dev Zig 0.15.2 and reviewed branch Zig 0.17.0. Their C wrapper reused this job's auth-tools/cache. I preserved dev-build-initial-red.log and am retrying with only that job-local cache cold (old cache retained). This is a cache-isolation hypothesis, not yet a result. The retry is queued on compute01 (PID 3342046); fresh size deltas, paired perf measurements and dev OSC52 comparison remain pending. No gates rerun, no merge/push/deployment.

J390 re-review verdict: REQUEST CHANGES.

Reviewed libghostty-vt-1.0 at 267d2c809d0aaaa80671c4aa664ce437ba64e1c5; verification used the clean scratch merge 1b05ae84971f71cab54f435264bbb9b67355c460 with dev 9965911c8ac2848168f5947f623488c75631c320. No integration merge, push, or deployment was performed.

Findings:

  • P1: notices do not survive public signed publication (comment 86985). scripts/package-release and the transport tarball contain the notices, but scripts/release/build:33 overwrites SHA256SUMS with a fixed root inventory; scripts/release/publish omits the notices; the downloader allowlist and release signer exclude nested licence objects. The release/build fixture reproduces the missing manifest entries. Reproducer patch is attached in the earlier comment (local-only commit 1f008bfb90873814eca70bfbbd1b7ae30630da52). Carry notices through the complete signed publication/download path, with a regression covering that path.
  • P2: mouse probe still calls removed 1.0 APIs (comment 87753). cargo test --locked -p infraternal-shim --features vt-test-input --test mouse exits 101 because tests/native/mouse_probe.c:12,14 uses ghostty_mouse_encoder_setopt_from_terminal and ghostty_mouse_encoder_setopt. The new APIs are ghostty_mouse_encoder_set_from_terminal and ghostty_mouse_encoder_set. This is a compile regression; I am not claiming a runtime mouse regression.
  • P3: size provenance misattributes the combined control delta (comment 87761). docs/verification/libghostty-vt-1.0-size-provenance.md:82–85 treats private logging as a separate check, but the product enables session-image in both measured revisions. The direct pair includes section emission and logger removal; correct the attribution or provide an isolated comparison. The preserved binary hashes and reported sizes match.

Other verification:

  • Licence contents match the signed engine and dependency sources; MIT, Apache-2.0, BSD-3-Clause and Unicode-3.0 are compatible with AGPL-3.0-only. Local package SHA256SUMS covers all 12 notice objects. Transport tarball and evaluated Nix install-phase harness retain them at share/licenses/infraternal/libghostty-vt/. The Nix check is an install-phase harness, not a complete derivation build.
  • Native archives contain function and data sections. Ordinary builds retain logging exports; private session-image archives omit them. Preserved pre-P2/P2 product deltas are −356,064 B x86_64 and −337,616 B aarch64, representing the combined controls.
  • Shim, session-image, compact-history, replay, reconnect and process-per-user checks passed (logs attached). The process-per-user server integration passed 2/2 with a short HOME after the original fixture exceeded Unix socket path length.
  • Upstream VT minimal-feature Debug run: 3295 passed /155 skipped /221 failed, 37 logged errors and 3 leak reports. These fixtures assume optional APIs disabled by that invocation. The upstream-default enabled-feature diagnostic passed all 549 selected tests, including every one of those 221 failed test names; coverage is recorded in vt-delta-coverage.json. The minimal run is not represented as green.
  • macOS build/check and session-shell tests passed (macos-build-check: PASS, MAC_EXIT=0). Both Linux static architectures built without PT_INTERP.

Fresh size comparison (compute01, same physical target and scripts/static-cargo recipe; complete hashes in size-summary.json and both provenance receipts):

Payload Architecture dev bytes Reviewed merge bytes Delta
product x86_64 28,172,584 28,225,752 +53,168 (+0.189%)
product aarch64 25,305,312 25,341,656 +36,344 (+0.144%)
session image x86_64 2,316,720 2,369,560 +52,840 (+2.281%)
session image aarch64 2,037,856 2,070,504 +32,648 (+1.602%)

The first dev native-C build failed parsing cached dependency files. The retry with only the job-local C cache cold passed (MATCHED_dev_BUILD_EXIT=0, RETRY_DEV_EXIT=0); both attempts are retained. Sources and pins were unchanged. This comparison includes the engine/build-recipe changes and Zig 0.15.2 → 0.17.0, not an isolated engine attribution. The two source snapshots have identical Cargo.lock and flake.lock hashes.

Parser performance: production release session-image adapter, identical measured_parser workload (100 × 392,340 bytes of ASCII/CRLF output, 200×60 terminal), one warmup per executable followed by seven alternating pairs. On the perf VM under perf-run CPU 1–3 /6 GiB, dev median 207.77 MB/s (201.59–210.02), reviewed merge median 223.63 MB/s (211.27–228.52). Median paired gain 7.61%, paired range +4.80% to +9.92%; ratio of medians +7.63%. Every pair improved. Before/after quiet checks passed; steal during run was 0/1805 jiffies. PERF_PAIRS_EXIT=0. Raw samples, binary hashes, machine snapshots and summary JSON/CSV are in the perf evidence attachment. This is one parser workload, not a claim about every terminal operation.

Real compute01 branch-server smoke: vim saved the exact Unicode input, htop entered/exited, and wide-character/combining output passed on both branch and frozen dev. OSC 52 copy did not change the browser clipboard on either binary, although the escape sequence was delivered through the PTY. The smoke is not represented as wholly green and the comparison does not establish an upgrade regression. Both reports and real production-build screenshots are retained/attached. The harness deliberately reports per-check status even when its process exit is zero.

All requested checks have finished. The compute01 scratch merge remains clean. No job build target is retained on compute01 or the Mac; evidence and the copied measurement binaries remain outside the deleted target. No review-owned server/browser/build/benchmark remains running. The optional inline chart preview failed because the control host lacks browser libraries (including libnspr4.so/libnss3.so); this does not affect the recorded compute01 browser smoke.

J390: requested compute01 gates on clean scratch merge 1b05ae84971f71cab54f435264bbb9b67355c460 (reviewed 267d2c809, dev 9965911c8) both passed, through build-slot and nix develop -c. The full unedited logs are attached. No #421 red occurred.

Fresh size comparison (compute01, same physical target and `scripts/static-cargo` recipe; complete hashes in `size-summary.json` and both provenance receipts): | Payload | Architecture | dev bytes | Reviewed merge bytes | Delta | | --- | --- | ---: | ---: | ---: | | product | x86_64 | 28,172,584 | 28,225,752 | +53,168 (+0.189%) | | product | aarch64 | 25,305,312 | 25,341,656 | +36,344 (+0.144%) | | session image | x86_64 | 2,316,720 | 2,369,560 | +52,840 (+2.281%) | | session image | aarch64 | 2,037,856 | 2,070,504 | +32,648 (+1.602%) | The first dev native-C build failed parsing cached dependency files. The retry with only the job-local C cache cold passed (`MATCHED_dev_BUILD_EXIT=0`, `RETRY_DEV_EXIT=0`); both attempts are retained. Sources and pins were unchanged. This comparison includes the engine/build-recipe changes and Zig 0.15.2 → 0.17.0, not an isolated engine attribution. The two source snapshots have identical Cargo.lock and flake.lock hashes. Parser performance: production release `session-image` adapter, identical `measured_parser` workload (100 × 392,340 bytes of ASCII/CRLF output, 200×60 terminal), one warmup per executable followed by seven alternating pairs. On the perf VM under `perf-run` CPU 1–3 /6 GiB, dev median **207.77 MB/s** (201.59–210.02), reviewed merge median **223.63 MB/s** (211.27–228.52). Median paired gain **7.61%**, paired range **+4.80% to +9.92%**; ratio of medians +7.63%. Every pair improved. Before/after quiet checks passed; steal during run was 0/1805 jiffies. `PERF_PAIRS_EXIT=0`. Raw samples, binary hashes, machine snapshots and summary JSON/CSV are in the perf evidence attachment. This is one parser workload, not a claim about every terminal operation. Real compute01 branch-server smoke: vim saved the exact Unicode input, htop entered/exited, and wide-character/combining output passed on both branch and frozen dev. **OSC 52 copy did not change the browser clipboard on either binary**, although the escape sequence was delivered through the PTY. The smoke is not represented as wholly green and the comparison does not establish an upgrade regression. Both reports and real production-build screenshots are retained/attached. The harness deliberately reports per-check status even when its process exit is zero. All requested checks have finished. The compute01 scratch merge remains clean. No job build target is retained on compute01 or the Mac; evidence and the copied measurement binaries remain outside the deleted target. No review-owned server/browser/build/benchmark remains running. The optional inline chart preview failed because the control host lacks browser libraries (including libnspr4.so/libnss3.so); this does not affect the recorded compute01 browser smoke. J390: requested compute01 gates on clean scratch merge `1b05ae84971f71cab54f435264bbb9b67355c460` (reviewed `267d2c809`, dev `9965911c8`) both passed, through build-slot and `nix develop -c`.

J339 follow-up started. Existing branch libghostty-vt-1.0 is at 267d2c809d0aaaa80671c4aa664ce437ba64e1c5; fetched origin/dev is 0a5432d2c1347c57bf1a6c57e368877599d57587. I will rebase the feature branch onto that current dev head before edits, following the repository workflow; I will not merge the feature branch to dev.

Plan (estimate: 3–5 active hours plus build-slot queue): (1) add and run a red regression through signed release publication, then carry notices through its manifest/signing/download allow-lists; (2) reproduce the mouse probe compile failure and port it to the 1.0 setters if the probe still covers behavior; (3) correct the size-provenance wording so the measured product delta is labeled as the combined section/logger effect unless isolated evidence supports separate attribution. Commit the three findings separately, run verify quick then verify fast on compute01, and post final head/gate output here.

P1 finding confirmed with test-first regressions (no production edits yet). On dev-02, python3 scripts/release/test.py fails in four checks: the release builder's signed-root checksum list omits all 12 licenses/libghostty-vt/ notices; the local publication fixture observes 14 uploaded objects versus 26 expected; a bundle missing Unicode-3.0.txt is accepted for upload (exit 0); and the fixture's signed manifest omits the notice paths. Evidence: /home/claude/.cache/codex-scratch/j339-review-fixes/evidence/p1-release-red-final.log.

The release-signer Worker test is red too: entry.files contains only VERSION and the five binaries, and signing succeeds (HTTP 200) after the Unicode notice is removed (expected 409). Evidence: /home/claude/.cache/codex-scratch/j339-review-fixes/evidence/p1-worker-red-clean.log.

Next I am carrying the fixed notice inventory through build checksums, publisher uploads, signer requirements, and verified downloads; the test will also confirm missing or modified notice objects fail verification.

P1 fix committed and pushed as 8c2d66cca (fix: include VT notices in signed releases (#419)). The release builder now covers all 12 notice paths in the signed root checksums; publication uploads and compares them; the signer refuses new signatures when any is absent; and the verifier accepts only those nested notice paths, creates their download directories, validates complete notice sets when present, and checks their signed hashes. Old signed releases with no notice paths remain verifiable.

Green evidence on dev-02: scripts/release/test.py ran 9 tests and passed (/home/claude/.cache/codex-scratch/j339-review-fixes/evidence/p1-release-green2.log); bun test scripts/release/worker.test.ts ran 4 tests and passed (.../p1-worker-green.log); scripts/test-vt-release-notices.py passed with the preserved static x86 artifact (.../vt-local-notices-green.log). The regression checks exercise the signed manifest, public object list, required notice set, and missing/modified notice downloads.

P3 provenance correction committed and pushed as 80fb025b7 (docs: label the combined VT size controls (#419)). The direct pre-P2/P2 product pair includes restored function/data section emission and removal of the private session-image logger symbols; both product builds enable session-image. The document now states the reported -356,064/-337,616 byte deltas combine those controls and cannot be separately attributed. It also clarifies that the private-only archive symbol check is not an isolated product size measurement. Evidence is the updated “Direct P2 size-control comparison” paragraph in docs/verification/libghostty-vt-1.0-size-provenance.md.

P2 finding confirmed before editing. cargo test --locked -p infraternal-shim --features vt-test-input --test mouse exited 101. The native compiler reports ghostty_mouse_encoder_setopt_from_terminal and ghostty_mouse_encoder_setopt as undeclared at tests/native/mouse_probe.c:12,14; the captured compiler output also points to the 1.0 header's uint8_t * encode buffer. Evidence: /home/claude/.cache/codex-scratch/j339-review-fixes/evidence/p2-mouse-red-v2.log and /home/claude/.cache/codex-scratch/infraternal-shim-tests/evidence/mouse-856572/stderr.log.

The probe remains useful: it checks that faithful snapshot/replay preserves public mouse reports across tracking-mode changes. I will port it to ghostty_mouse_encoder_set_from_terminal and ghostty_mouse_encoder_set, retaining the 1.0 GHOSTTY_MOUSE_ENCODER_OPT_SIZE option and using the byte-buffer type declared by the API.

Base update before the final green run: after fetching, origin/dev is now 44e80ccc5e1462bc19ae34979c2edf23c525a967 (#438), four commits beyond this branch's current merge base 0a5432d2c1347c57bf1a6c57e368877599d57587. The P2 green test is still queued and has not started. I will rebase this branch onto 44e80ccc5, update the test worktree to that rebased head, then finish the P2 red/green pair and run the requested gates. No merge to dev.

P2 fix committed and pushed as 8cd1475ad9a8ce05fe9583bb5e669b356d105f5a. The retained probe still checks faithful snapshot/replay of public mouse reports across tracking-mode changes; libghostty-vt 1.0 does not make that behavior check redundant. It now uses ghostty_mouse_encoder_set_from_terminal, ghostty_mouse_encoder_set, and the declared uint8_t * output buffer. The current dev-02 quick gate is queued; I will post the fresh focused-test and gate results when they finish.

Gate finding: the first verify quick run stopped at doc comments on diff with scripts/release/worker.test.ts:23: fixture needs a doc comment (D345). The new release-signer fixture was added with the P1 notice regression and lacked the required function comment; the full log is /home/claude/.cache/codex-scratch/j339-review-fixes/evidence/verify-quick.log. I added the fixture comment and autosquashed it into the P1 notice-publication commit to keep one commit per review finding. The rewritten branch head is fbfd48c3b32647ce2aad7b9e10c8d168c613c77d; I am rerunning quick before the focused mouse test and fast gate.

J339c progress: J339's P1 (notices in signed publication, 79cac8148), P2 (mouse probe ported to 1.0, kept because it still checks snapshot/replay of mouse reports, e0d879000) and P3 (size provenance labelled as combined, 39a46de3d) were already on the branch.

I merged origin/dev (966c52e07) with no conflicts and pushed `36fef2b430f2e34fc625af0061ea0cb67a9b75c7` (confirmed with `git ls-remote`). I stopped J339's stale `verify fast` run on the old head (`e0d879000`) on compute01 and started a fresh one on `36fef2b43`. Log: `/home/claude/.cache/codex-scratch/j339-review-fixes/evidence/verify-fast-36fef.log`. `verify quick` follows.

J339c finish. Branch libghostty-vt-1.0, head ee7ab5db62e66f63dc217e93939207c962a7cb8a (pushed; git ls-remote agrees). origin/dev e34516d19 is merged.

J390's findings were already fixed by J339 and are on the branch: P1 notices in the signed publication (79cac8148, with a release-signer test), P2 mouse probe ported to 1.0 and kept (e0d879000; 1.0 does not make its snapshot/replay check redundant), P3 size provenance labelled as combined (39a46de3d). This job only merged dev and re-ran the gates; no code changed.

scripts/verify quick on dev-02: pass (115 shim unit tests passed, 14 ignored). Log: verify-quick-36fef.log.

scripts/verify fast on compute01: VERIFY_EXIT=0. All 24 rows PASS, including release component publication, shim process-per-user, privileged integration and static builds. Log: /home/claude/.cache/codex-scratch/j339-review-fixes/evidence/verify-fast-36fef.log.

Static sizes (report only, D243 amended 2026-11-01): x86_64 musl 28230744 bytes (baseline 22418256, +5812488); aarch64 musl 25346776 bytes (baseline 20453280, +4893496). These deltas are against the gate's stored baseline, not a same-day dev build, so they are not the 53 KB J390 measured; I did not re-measure that.

Both gates were killed twice while queued by something outside this job. I ran them as systemd user units with an explicit PATH.

Fix-check verdict: APPROVE for libghostty-vt-1.0 at ee7ab5db62e66f63dc217e93939207c962a7cb8a (git ls-remote origin libghostty-vt-1.0 shows the same SHA). I merged nothing, pushed nothing and deployed nothing.

1. The three fixes

  • P1, notices in the signed release: closed. 79cac8148 adds the 12 notice paths to scripts/release/common, and release/build now checksums them. release/publish uploads them, and the downloader allowlist accepts them and requires all 12 or none, so older signed releases still verify. The signer lists nested notice objects and refuses to sign when any is missing.
    • I copied ee7ab5db6 into scratch trees on compute01 and applied one mutation to each.
    • Green: bun test scripts/release/worker.test.ts gives 4 pass, 0 fail. python3 scripts/release/test.py gives 9 tests OK.
    • M1, signer refusal deleted: refuses to sign a release that omits any engine or dependency notice fails (3 pass, 1 fail). The signer would then sign a bucket without the notices.
    • M2, signer filter reverted to drop nested names: signs stable… and signs edge… fail (2 pass, 2 fail), because the notices are missing from the signed manifest.
    • M3, publish file list without the notices: test.py fails, 3 failures of 9 (the new missing-notice test is not among them; they are the existing publication cases).
    • The scratch trees are deleted.
    • Not mutated: the awk allowlist in verify_download. The Python tests do cover its behaviour end to end: they delete a signed notice and tamper with another, and each time verify must fail.
  • P2, mouse probe: closed at compile level. e0d879000 switches to ghostty_mouse_encoder_set_from_terminal and ghostty_mouse_encoder_set, checks both return codes, and uses a uint8_t buffer.
    • I downloaded the pinned libghostty-vt-1.0.0.tar.gz; its sha256 matches scripts/libghostty-vt.sha256.
    • Compiled with the nix-shell cc, -fsyntax-only -Wall -I include: the pre-fix probe (e0d879000~1) fails with two implicit-declaration errors (…setopt_from_terminal, …setopt), and the fixed probe compiles. The only warning is a misleading-indentation note on a line that was already there.
    • Gap: I did not run the runtime test cargo test -p infraternal-shim --features vt-test-input --test mouse. In the fast log, tests/mouse.rs ran "0 tests" because the feature is off, so verify fast never exercises this probe. J339's p2-mouse-green.log holds only a build-slot queue line (70 bytes), no result. compute01's queue was 9 deep, so I did not queue the run. Please run it once at merge.
  • P3, size provenance: closed. 39a46de3d only changes wording. The doc now says the −356,064 / −337,616 B pair combines section emission and logger-symbol removal, that both builds enable session-image, and that the private-only archive check is not a separate size measurement. That is the attribution J390 asked for, and it matches what J390 found. No isolated comparison was added.

2. Fast log

The log is ~/.cache/codex-scratch/j339-review-fixes/evidence/verify-fast-36fef.log on compute01. Line 4 prints ee7ab5db62e66f63dc217e93939207c962a7cb8a, and the last line is VERIFY_EXIT=0. All 24 rows of the Rust gate table are PASS, from Nix Cargo vendoring through static builds, including privileged integration and shim process-per-user. The log has 0 (fail) lines. The bun protocol tests ended at 50 pass, 0 fail.

  • The filename says 36fef but the run was at ee7ab5db6. The diff 36fef2b43..ee7ab5db6 is DECISIONS.md only (+46 lines).
  • The log shows nightly fuzz: could not take a build slot inside a row that still reports PASS; I read that as the reporter test's expected path.

3. Static size

  • The +5,812,488 B (x86_64) and +4,893,496 B (aarch64) are against a stale baseline. scripts/verify.d/rust.sh:116 has baseline_bytes=22418256, last ratcheted on 2026-11-02 in a8926703a.
  • The matched build is J390's on this issue (same physical target, same scripts/static-cargo recipe, dev 9965911c8 from 2026-11-08). Dev is already 28,172,584 B on x86_64, so dev alone grew about 5.75 MB over the baseline in seven days.
  • This branch is +53,168 B x86_64 (+0.189%) and +36,344 B aarch64 (+0.144%) against that dev build.
  • The fast log's branch binary is 28,230,744 B. Against 28,172,584 B that is +58,160 B (+0.21%), which is consistent with J390's +53,168 B plus later dev content.
  • The log's aarch64 binary is 25,346,776 B against J390's dev 25,305,312 B, +41,464 B (+0.16%), which is consistent with J390's +36,344 B.
  • J390 also noted that the engine/build-recipe changes and Zig 0.15.2 → 0.17.0 are included in the delta, not isolated.
  • I did not run a fresh dev build today. origin/dev is 106 commits past 9965911c8, mostly ssh plugin and UI, so another hours-long static build pair would only change the figures slightly. Per the 2026-11-01 owner rule the size is report-only.
  • Suggested follow-up for the orchestrator: ratchet the gate baseline when this merges.

Non-blocking, for the merge

  1. Run the mouse runtime test once.
  2. Ratchet the size baseline.
  3. The OSC 52 clipboard gap J390 saw is separate from this branch (the same on frozen dev), and the #440 commits on dev address it.

J430: static size baseline ratchet at 1a0be9343

Branch ratchet-size-baseline-419, one commit 5bca4c0b8 on base 1a0be9343 (not merged). It changes scripts/verify.d/rust.sh (both baseline_bytes) and the PROCESS.md §7 table. It is pushed; git ls-remote origin ratchet-size-baseline-419 returns 5bca4c0b8cfe82dfc751035ee1aee89331d811a1.

Build: scripts/auth-toolchain, then scripts/static-cargo build --locked --release --package infraternal --target <t> for both targets, on compute01 through build-slot (worktree ~/worktrees/j430, detached at 1a0be9343). Log: ~/.cache/codex-scratch/j430/static-1a0be9343.log.

Target Old baseline (2026-11-02) Measured at 1a0be9343 Delta
x86_64-unknown-linux-musl 22,418,256 28,268,440 +5,850,184
aarch64-unknown-linux-musl 20,453,280 25,378,504 +4,925,224

Both images have no PT_INTERP, and their ELF class and machine match the targets.

Gate's own size row, after the ratchet, on the same binaries (source scripts/verify.d/rust.sh; rust_check_static_binary <target>):

production trust: PASS (staging-trust authority absent)
target/x86_64-unknown-linux-musl/release/infraternal: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), static-pie linked, stripped

Note: the owner's brief put dev's growth at about 5.75 MB. The measured x86_64 growth is 5,850,184 B. The libghostty part is about 53 KB (x86_64) per the merge commit. The measured numbers are used here.
