J337: reproduce the a8926703a and origin/dev static x86_64-musl sizes with the same release profile on compute01; attribute growth across first-parent dev merges, inspect crate/symbol contributions, and implement only measured, safe cuts on size-trim-337. No baseline ratchet, merge, deployment, or unbenchmarked optimization-profile change.

J337 start: branch size-trim-337, base fba745051416c60a8523f0fe529c2aee6bbe0dd0 (origin/dev).

Plan: (1) reproduce a8926703a and pinned dev with identical static profile; (2) bisect first-parent merge intervals, then measure the dominant merges individually and inspect crate/symbol sizes; (3) test dependency/feature cuts one at a time, retaining only worthwhile behavior-preserving reductions; (4) atomic commits pushed immediately, quick then fast gate, final merge-byte table and raw logs. Baselines and release optimization settings remain untouched.

Estimate: 4 hours of execution plus the shared build queue, which currently has five occupied slots and 22 queued jobs. Stop and report if execution exceeds 8 hours. All builds foreground through build-slot on compute01, -j4, nice -n10. Exactly one target: /home/claude/.cache/codex-scratch/J337/target; evidence /home/claude/.cache/codex-scratch/J337/evidence and control-host /home/kayg/.cache/codex-scratch/J337/evidence.

J337 source/dependency finding (not yet byte attribution): pinned dev's Linux normal dependency tree contains ring, rustls and vendored OpenSSL, but no AWS-LC/native-tls. The GotaTun reverse feature tree enables only device, socket, and ring; its manifest disables default features explicitly. GotaTun uses RustCrypto XChaCha20Poly1305 in noise/rate_limiter.rs and noise/handshake.rs, so those older crypto dependencies are live cookie-protocol code, not obviously redundant implementations to delete.

Historical receipts are leads only: #260 records x86 size 24,768,176 B at follow-up c361c357d based on efbd863e2; #221 records 25,553,008 B on the mesh SSH branch. Different bases prevent assigning their differences to individual merges. The matched endpoint build is foreground-queued behind 22 jobs; launcher check passed with cargo 1.99.0. No code changed and no size-saving claim yet.

Artifacts: compute01 /home/claude/.cache/codex-scratch/J337/evidence/{normal-tree-dev.txt,duplicates-dev.txt,gotatun-features.txt}; control host /home/kayg/.cache/codex-scratch/J337/evidence/{issue-260-comments.txt,issue-221-comments.txt,first-parent-merges.txt}.

J337 evidence attachments: current Linux feature selection, normal dependency tree, and duplicate-name inventory. These establish the enabled dependencies, not their linked byte cost. The matched static-size run is still foreground-queued; no product code changed.

J337 ~30-minute preservation update: no repository code changed; branch still size-trim-337 at base fba745051416c60a8523f0fe529c2aee6bbe0dd0. The single foreground request (remote build-slot PID 1723403) remains queued on compute01; the queue is moving as older jobs finish. No extra slot or build host used.

Resume material is outside the checkout: control /home/kayg/.cache/codex-scratch/J337/ and compute01 /home/claude/.cache/codex-scratch/J337/ hold measure.sh, symbols.sh, symbol-diff.py, and bisect.py. The run performs untouched-dev quick precheck, matched baseline/dev shipping static builds, symbol retention without changing opt-level/LTO, and largest-first first-parent interval measurements. Raw logs go in evidence/; the one target is target/ there. merge-measurements.json and merge-table.md are written after every completed bisection measurement. Initial queue status is preserved in evidence/queue-status.txt. No byte-saving or gate-pass claim yet.

J337 resource update: same foreground request PID 1723403 remains at queue position 16 (23 queued total). compute01 free disk is now 33 GB, down from 104 GB at start; build-slot floor is 25 GB. No J337 Rust build has started and its target has not been populated. Queue snapshot artifact: /home/claude/.cache/codex-scratch/J337/evidence/queue-status.txt. I am leaving other jobs and their targets untouched and continuing the foreground wait.

J337 blocked on build admission: compute01 now has 6 GB free against build-slot's 25 GB floor. Slots 3 and 5 are free, but the same J337 foreground request PID 1723403 remains at queue position 16 (24 total queued). No J337 build or target allocation has started. The previous snapshot had 33 GB free; it is preserved separately.

Raw artifacts: compute01 /home/claude/.cache/codex-scratch/J337/evidence/queue-status.txt (6 GB), queue-status-33g.txt (33 GB). Recommendation for the orchestrator: have finished jobs clean their own targets under the common brief; I will not remove or alter other jobs' files. No repository changes, no new run submitted, no claimed static measurement or gate pass. Continuing the existing foreground wait.

J337 admitted at 06:29 IST (2026-11-07): the original foreground request acquired slot 4/5. Exact launcher again reports cargo 1.99.0 (5f94df478 2026-08-27). Untouched-dev quick precheck is now running, followed by the pinned baseline/dev builds and merge attribution. Logs: /home/claude/.cache/codex-scratch/J337/evidence/endpoints.log and quick-initial.log. One target, one slot, -j4, nice -n10; no source changes.

J337 dependency finding: matched Linux normal graphs contain 318 crate names / 343 name-version pairs / 21 duplicated names at a8926703a, versus 347 / 380 / 29 at pinned dev. Exactly 37 name-version pairs were added and none removed. Additions include GotaTun plus its older aead/cipher/curve25519/chacha/poly1305 stack, proxy flate2/tar/xattr support, and qrcodegen. OpenSSL and rustls already occur at baseline; no newly added AWS-LC/native-tls appears in the Linux graph. This is dependency visibility, not a linked-byte estimate. Raw artifact: /home/claude/.cache/codex-scratch/J337/evidence/dependency-diff.json, with both normal-tree files beside it.

J337 matched endpoint result: +5,367,936 bytes (+23.94%), confirming the reported growth.

Revision	Stripped static x86_64-musl bytes	SHA-256
`a8926703ae`	22,419,344	b9b856894d55498f9e16b1ebdcedaeaeeee50224793e1714c5b965a2a902e69b

Both file results are static PIE, x86-64, stripped. Same compute01 worktree, Cargo 1.99.0, existing release profile, scripts/static-cargo build --locked --release --package infraternal --target x86_64-unknown-linux-musl -j4, one target and one foreground slot, nice -n10. No code, optimization, LTO, or baseline changes.

Baseline symbolic diagnostic validation: .text, .rodata, .eh_frame, .gcc_except_table and .data.rel.ro have identical byte hashes between the shipping image and the symbol-retaining diagnostic after GNU strip. Only the non-runtime ELF bookkeeping differs (8 bytes). Thus the diagnostic has the same optimized code/data/unwind bytes for attribution. Raw validation: baseline-symbol-layout.json.

The stored D243 reference was measured from 502d0fc7e, not the requested a8926703a tree; production remote-WebSocket files differ between them. The fresh a892 build is 1,088 bytes above the stored 22,418,256-byte value. The growth above uses fresh matched measurements.

Raw evidence: compute01 /home/claude/.cache/codex-scratch/J337/evidence/ holds endpoints.log, both build-*.log endpoint logs, sections-*.txt, exact endpoint binaries infraternal-*, baseline symbols, baseline-symbol-layout.json, and normal dependency inventories. Control copy: /home/kayg/.cache/codex-scratch/J337/evidence/; stored-baseline-source-diff.txt records the different comparison trees.

Next in the same foreground run: retain dev symbols, then bisect largest first-parent intervals and inspect the two largest isolated merge symbol diffs. No byte savings or final gate pass claimed yet.

J337 attribution blocker/fix: both requested endpoints and optimized symbol listings completed. The first midpoint 7bbbd0e52 fails unchanged static compilation with Rust E0063: missing field proxy_containment in initializer of MeshNodePlugin, crates/plugins/mesh/src/node_actions.rs:258. The foreground run exited 1 and released its slot; this is not a size result. Raw failure: compute01 evidence/build-7bbbd0e52*.log, traceback/exit marker in evidence/endpoints.log.

History proves the fix is merge 070c9a0b6, which adds exactly proxy_containment: None to that initializer. Intervening merges da02013c8 and 990022655 retain the unfixed source. Only 7bbbd0e52 was compiled; its two successors will be explicitly labeled unbuilt source skips, not falsely reported as tested failures.

The measurement driver now checkpoints/resumes completed sizes, records Rust source errors as skips, and stops on infrastructure errors. It chooses a buildable neighboring midpoint without patching history. Same target, profile, pinned endpoints, VM and foreground launcher; no repeated endpoint builds and no repository edits. The initial precheck is preserved. Endpoint symbol diff is already available at compute01 /home/claude/.cache/codex-scratch/J337/evidence/symbol-growth-endpoints.md (top new symbols include mesh SSH signing/server dispatch, fixed-base curve tables, remote recovery, and GotaTun worker/packet code). No merge byte attribution is claimed before the resumed measurements.

J337 resumed the saved attribution run. Both endpoint diagnostic symbol images now match all 24 allocated ELF sections of their shipping binaries exactly (addresses, sizes and contents): symbol-layout-a8926703a.json and symbol-layout-fba745051416c60a8523f0fe529c2aee6bbe0dd0.json under compute01 ~/.cache/codex-scratch/J337/evidence/.

The corrected bisection driver is queued once, in the foreground, through the required compute01 build-slot launcher. Exact launcher preflight passed: cargo 1.99.0 (5f94df478 2026-08-27). Current queue is long (17 queued jobs, five occupied slots); no duplicate submission or second target. Existing target: /home/claude/.cache/codex-scratch/J337/target.

The historical 7bbbd0e52 compilation failure is retained as evidence. Its two successors are explicitly labelled source-inspected, unbuilt skips until the proxy_containment: None fix at 070c9a0b6. The driver will preserve unresolved intervals rather than attribute an interval's bytes to one unmeasured merge.

No repository edits or cuts selected yet. Endpoint symbol growth includes SSH signing/verification and mesh SSH server code as well as GotaTun. Removing broad SSH algorithm support would alter compatibility and is not an acceptable blind feature trim. OpenSSL/rustls coexistence predates this growth; GotaTun's RustCrypto cookie encryption is used. Final merge attribution and measured safe-cut assessment remain pending.

Its two successors are explicitly labelled source-inspected, unbuilt skips until the `proxy_containment: None` fix at `070c9a0b6`. The driver will preserve unresolved intervals rather than attribute an interval's bytes to one unmeasured merge. No repository edits or cuts selected yet. Endpoint symbol growth includes SSH signing/verification and mesh SSH server code as well as GotaTun. Removing broad SSH algorithm support would alter compatibility and is not an acceptable blind feature trim. OpenSSL/rustls coexistence predates this growth; GotaTun's RustCrypto cookie encryption is used. Final merge attribution and measured safe-cut assessment remain pending.

J337 verified endpoint symbol evidence: retaining symbols for the final-crate diagnostic relink preserves every allocated ELF section of both stripped shipping binaries exactly (24 sections each, matching addresses, sizes and byte hashes). Thus the diagnostic text-symbol diff is evidence for the measured shipping images, despite GNU strip making the diagnostic file's nonallocated headers 8 bytes smaller.

Of the +5,367,936-byte artifact growth, .text adds 4,146,046 B; .eh_frame, .gcc_except_table and .eh_frame_hdr together add 606,432 B; .rodata adds 327,808 B; .data adds 199,712 B. No release debug sections are present. Disabling unwinding would change task panic isolation and is not an eligible trim.

Endpoint symbol additions include mesh SSH's russh server reply (62,912 B), the generic SSH keypair signer (55,966 B), primeorder basepoint-table initialization for p256/p384/p521 (114,693 B combined), remote TCP handling (44,565 B), and GotaTun's worker (35,763 B) and incoming packet processing. These are symbol observations across the complete interval, not isolated merge costs. First-parent builds are still needed for causal attribution.

One safe feature experiment is prepared: disable tar's default xattr support in both proxy dependency sections. Production extraction reads entries directly and does not call unpack APIs; direct cgroup xattr reads remain enabled. Its byte saving is not yet measured, and LTO may already remove all unused code. No change is retained without a worthwhile measured saving.

Infrastructure blocker: the single foreground resumed run is queued on compute01; five slots occupied and 20 GB free, below the 25 GB start floor. No second submission or target exists. The existing endpoint reports, logs and binaries remain under /home/claude/.cache/codex-scratch/J337/evidence/; the target is /home/claude/.cache/codex-scratch/J337/target. No repository edits.

J337 checkpoint: the one resumed foreground run remains queued on compute01. No additional target, build-slot submission or repository edit. Endpoint and symbol validation reports are attached in comment 83437. Source trim audit is saved at /home/kayg/.cache/codex-scratch/J337/evidence/cut-audit.md and mirrored to compute01's evidence directory.

Correction/clarification to the exploratory SSH hypothesis: production host-access sessions use external SSH, not the russh client. Production russh calls are the mesh SSH server. That server inherits the default KEX preferences, which offer NIST P-256/P-384/P-521; these curves therefore remain live independent of its Ed25519 host keys. Dropping curve dependencies would change negotiated support. A specialized host-signing API is a separate security-sensitive follow-up, not a blind safe feature trim.

The only prepared low-risk experiment is disabling tar's default xattr feature, preserving the direct cgroup xattr dependency. try-tar-xattr.py runs after bisection in the same slot, saves a paired-size receipt, and restores both manifest and lockfile. No saving is claimed yet. The resumable bisection driver now also saves/validates the allocated ELF sections around each isolated large-merge symbol diff.

Run: recorded build-slot PID 3920575, foreground session still held. Launcher: ~/infraternal-ops/build-slot nice -n10 nix develop ~/worktrees/J337 -c bash /home/claude/.cache/codex-scratch/J337/resume.sh. Target remains /home/claude/.cache/codex-scratch/J337/target; eventual log is evidence/bisect-resume.log beside it. Queue time is excluded from the previously posted execution estimate.

J337 infrastructure update: compute01 build-slot --status now reports 9 GB free, below the mandatory 25 GB launch floor. All five slots remain occupied and J337 is still queued (recorded PID 3920575; no duplicate submission). No resumed bisection build has started.

Our single target was inspected for safe cleanup: auth-tools 463 MB, host release 302 MB, vt-tools 971 MB, musl release 1.8 GB; no target/debug exists. These are the cached static-build inputs required for attribution, not a leftover full debug gate. No other job's files were touched. Evidence directories and endpoint attachments are preserved.

The foreground wait continues. New attribution and tar-feature byte results remain pending shared disk/slot availability; no repository edits, commits, saving claim, baseline ratchet, merge or deployment.

J337 90-minute queue checkpoint: the resumed foreground run is now first in the queue, but all five slots remain occupied and free disk is 11 GB, below the 25 GB launch floor. Receipt: /home/kayg/.cache/codex-scratch/J337/evidence/queue-90min.txt. No resumed bisection or tar-xattr build has started. One submission (PID 3920575), one small static-build target, no repository edits; foreground polling continues.

Additional source checks are saved in evidence/cut-audit.md: russh unconditionally calls ssh-key's feature-gated from_ppk and decrypt, so disabling those features requires matching engine API changes rather than a manifest-only edit. Also verified that requested baseline a8926703a and its dev merge a479a8760 share exact Git tree 56632d90092a92447f20273f3561cc6c15c36f1c; receipt evidence/baseline-dev-join.txt on both hosts. The bisection report explicitly labels that initial source-equivalent bridge and keeps unresolved interval totals distinct from isolated merge costs.

J337 resumed bisection has acquired compute01 slot 1/5 after roughly 100 minutes in the foreground queue. The exact launcher again reports cargo 1.99.0 (5f94df478 2026-08-27). First buildable midpoint is c06d1ce63, immediately before the known broken initializer interval. It is building unchanged historical source with the same release profile, shipping static recipe, target directory and -j4/nice policy as the endpoint builds.

Live receipts: compute01 /home/claude/.cache/codex-scratch/J337/evidence/bisect-resume.log, build-c06d1ce63*.log, and checkpointed merge-measurements.json / merge-skips.json / merge-table.md. No repository edits or cuts retained. The foreground run continues through attribution, selected large-merge symbol diffs and the reversible tar-xattr experiment.

J337 first resumed midpoint completed: unchanged c06d1ce63b6a84a7f136aba3ea8800fdbaadbcc0 builds to 23,385,200 bytes with the matched x86_64-musl shipping recipe. This milestone is +965,856 B above requested baseline a8926703a, before the Linux GotaTun merge efbd863e2. Therefore the Linux engine switch cannot explain the entire endpoint increase. This is an interval result, not a claim that the c06d1ce63 documentation merge itself added those bytes.

The remaining c06d1ce63..fba745051 interval is +4,402,080 B. The driver is now measuring midpoint 3e659eb78 inside that interval.

J337 midpoint 810dc1e04ee88b3cc93667d542b37f93c5cae5d7 measures 23,601,712 B, or +216,512 B from c06d1ce63 and +1,182,368 B from requested baseline a8926703a. This milestone precedes the Linux GotaTun and live mesh SSH integration merges. The next large interval, 810dc1e04..3e659eb78, is +3,573,760 B.

J337 integration-boundary milestone: unchanged f332ffed36e410f879d6497555907f65d929418a, after Linux GotaTun and before mesh SSH, measures 24,768,176 B. Matched interval accounting:

J337 additional generic-bloat candidate, still unmeasured/unretained: production mesh_authority::Guard::open_files always returns Err(Refusal::LoginAccess), as documented for slice 1. Its associated handler is nevertheless an inhabited unit struct, NoFiles. The optimized shipping symbols retain SFTP service cleanup code instantiated for that handler:

russh_sftp::server::serve_with_config<..., mesh_authority::NoFiles>
russh_sftp::server::process_request<mesh_authority::NoFiles>
russh_sftp::server::process_handler<mesh_authority::NoFiles, ...>
REFUSED_FILE_SERVICE_SYMBOLS=3

The external linked-code exclusion check was run against the untouched dev diagnostic and failed as expected (exit 1); receipt: compute01 evidence/nofiles-symbol-red.log, with exact sizes/addresses in nofiles-baseline-symbols.txt. This proves retained generic machinery, not the number of bytes a source change will save.

Prepared paired experiment: change the documented never-constructed handler to an empty enum so generic code can see that a successful file open is impossible. Keep the refusal implementation unchanged; keep generic SFTP support and its separate MemoryFiles fixtures. Workspace search finds no constructor use. Risk: source-level constructor availability narrows to the existing documented invariant; runtime file access continues to refuse. No profile, engine algorithm or protocol capability change.

try-nofiles.py will run after attribution and the restored tar experiment in the current foreground slot, record shipping before/after bytes, validate diagnostic allocated sections and run the linked-code check. It restores source before returning. No saving or implementation-complete claim yet. If worthwhile, the retained cut will get focused real-engine/refusal checks and the final gate on its commit.

The f332ffed3..e6cf46615 interval is +2,408,064 B; e6cf46615..3e659eb78 is −768 B. Thus the previously located 2.4 MB jump is already present at this earlier post-SSH milestone.

The current build is 19737d86d, the immediate first parent of mesh SSH merge 5f156b809. A build of the merge itself will provide the adjacent-parent measurement needed for individual attribution. No individual merge cost is claimed before both sides are measured.

J337 first isolated dominant merge: mesh SSH 5f156b80999c5afcb4a768f2cb7217dd653821d6 adds 2,266,144 B versus immediate first parent 19737d86d9eac6d556d769ee6e4bb7457a4353a9 (24,768,368 → 27,034,512 B). This is 42.22% of the full matched +5,367,936 B growth. The two following steps to e6cf46615 add a further 141,728 B together.

This is an adjacent-parent measurement, unlike earlier multi-merge intervals. It disproves attribution of the entire jump to the earlier Linux engine switch. Same shipping recipe/profile/host/target; optimized symbol diagnostics around the largest isolated merges follow bisection.

J337 exact adjacent-parent attribution: Linux GotaTun merge efbd863e2cc8ed064daa2c09bf11fbf0634aeb9d adds 871,584 B, from immediate parent c02bf3cdc3b1ec03258a439e00be05a670d2c252 23,896,528 B to 24,768,112 B. Parent c02bf3cdc has identical measured size to eb0684cbf; subsequent engine follow-ups through f332ffed3 add 64 B.

This is 16.24% of the full matched +5,367,936 B. Mesh SSH independently adds 2,266,144 B (42.22%). Together the two individually measured merges account for 3,137,728 B (58.45%). Thus GotaTun contributes, but is not the largest merge. Optimized symbol comparisons of the largest isolated boundaries follow bisection, so crate/function attribution remains pending those diagnostics.

J337 mesh SSH parent diagnostic is validated: shipping rebuild of 19737d86d remains 24,768,368 B; GNU-stripped diagnostic is 24,768,360 B, and all 24 allocated ELF sections have identical addresses, sizes and content hashes.

J337 isolated mesh SSH symbol attribution is validated. Both parent and merge diagnostics match all 24 allocated ELF sections (address, size, content hash) of their respective shipping images; only non-runtime ELF bookkeeping differs by 8 B after GNU strip. Whole-binary merge growth is 2,266,144 B; deduplicated optimized text symbols grow 1,684,044 B (18,753,602 → 20,437,646 B).

Artifacts (mirrored to control): `evidence/symbol-growth-efbd863e2cc8ed064daa2c09bf11fbf0634aeb9d.md`, `symbol-layout-c02bf3cdc3b1ec03258a439e00be05a670d2c252.json`, `symbol-layout-efbd863e2cc8ed064daa2c09bf11fbf0634aeb9d.json`; full listings/images and `bisect-resume.log` on compute01. Attribution completed **BISECT_EXIT=0**. The same foreground run restored pinned dev and started the tar-default-xattr experiment; NoFiles follows. No retained source edits or baseline changes.

J337 transport checkpoint: the long-lived foreground SSH session exited 255 after attribution completed. The remote build continued under the original build-slot PID 3920575 (one slot, no replacement submission). Its tar experiment child 3930081 / cargo 3930418 / rustc 3937876 were confirmed active; source changes were exactly the temporary proxy manifest and lockfile.

The original SSH-owned output pipe was not reopenable as claude; a foreground reader now follows the build-owned output pipe, saving any reconnected output in evidence/reconnected-output.log, while a foreground PID/log monitor waits for the original run to exit. The experiment JSONs and build logs remain authoritative. BISECT_EXIT=0, both validated merge function reports, all four layout validations, and the completed merge table are preserved; selected reports are mirrored to control. No repository edit retained or new heavy run launched.

J337 tar default-xattr experiment completed with no saving: 27,787,280 → 27,787,344 B, +64 B (saved_bytes = −64). The feature was disabled in both dependency declarations, direct cgroup xattr remained, and the package/version/source set was asserted unchanged. Both manifest and lockfile were restored before NoFiles began. Not retained: no binary-size benefit; not worth carrying a manifest-only change for this task. Source inspection found low functional risk because installation reads allowlisted entries instead of using tar unpack APIs.

Receipts: compute01 J337 evidence/trim-tar-xattr.json, trim-tar-xattr.patch, trim-tar-xattr-build.log, exact experiment image infraternal-trim-tar-xattr. JSON/patch mirrored to control. The original foreground-monitored run is already compiling NoFiles; no replacement build or new slot submission.

J337 retained the single safe cut and pushed atomic commit b91728d3ba on size-trim-337, based on current dev 3644950b8 (decision-document-only advance from the pinned attribution head). The source blob exactly matches the measured patch: 578523434e4b474cb64926aaf6b9196f9f5c08e1.

Measured saving: 72,704 B, shipping x86_64-musl 27,787,280 → 27,714,576 B. Optimized text symbols shrink 64,027 B. Both SFTP packet codecs disappear (23,821 + 18,501 B), along with a 9,032 B unreachable subsystem body and related serialization/cleanup. The NoFiles service symbol check changes from 3 (red) to 0 (green); all 24 allocated diagnostic sections match the trimmed shipping image.

The production authority still returns Err(Refusal::LoginAccess) for every file open. Only its documented never-constructed handler becomes an empty enum; generic file support and separate MemoryFiles fixtures remain. Risk: source constructor availability narrows to that existing invariant; workspace search found no constructor use. No runtime algorithm, protocol preference, optimization/LTO, panic setting, dependency version or D243 baseline changed. Tar default-xattr was rejected after growing 64 B.

Receipts mirrored to control J337 evidence: trim-nofiles.json, trim-nofiles.patch, symbol-layout-trim-nofiles.json, nofiles-symbol-green.log, symbol-diff-trim-nofiles.md; raw build logs and images preserved on compute01. Original measurement run finished RESUME_EXIT=0 and both foreground monitors exited.

Verification pending: quick plus existing real-engine SSH/SFTP/stock-client integration tests, then a separate verify fast run. Both host capacities were checked: compute01 8 queued / 5 slots, 52G free with our existing target; dev-02 4 queued / 1 slot, 43G free against 40G floor. Compute01 has lower queued work per slot and avoids a second target. The VM is synced to the exact commit, and the exact Nix launcher preflight is running before submission. No merge/deploy or baseline ratchet.

J337 verification admission is blocked by compute01 disk: 7G free / 25G floor, down from 52G at submission. Original single quick/focused request PID 70830 remains fifth in queue; no duplicate submission. All five slots are occupied. Dev-02 is also occupied, with five queued and 50G free / 40G floor.

Receipts on control: evidence/quick-capacity-compute.txt and quick-capacity-arm.txt; the exact launcher preflight passed cargo 1.99.0 before submission. Head b91728d3ba is already pushed. The measured static cut and linked-code check passed; quick/focused and final fast remain pending, not claimed green.

Recommendation: completed jobs clean their own targets under the common brief. J337 will not remove other jobs files. Its one existing target remains /home/claude/.cache/codex-scratch/J337/target; all raw evidence is outside it and preserved. Continuing foreground wait and checking both hosts; queue time is excluded from the execution leash.

J337 verification progress: pushed head remains b91728d3ba on size-trim-337. Fresh fetch confirms origin/dev remains 3644950b8e. The running quick + focused-test slot is still compiling a native dependency under workspace clippy, with active compiler children; no failure or success reported yet. Log: /home/claude/.cache/codex-scratch/J337/evidence/verify-quick-focused.log. Existing single target: /home/claude/.cache/codex-scratch/J337/target. After it exits, submit verify fast separately on compute01 per the latest brief correction (dev-02 privileged nf_tables gap). No additional cut, merge, deploy, or baseline change.

J337 verification finding: quick passed all rows; changed-package unit tests: 120 passed, 0 failed, 6 ignored. Focused mesh_requests_review (5), mesh_server (9), mesh_sftp (1), and mesh_stock_clients (1) all passed: QUICK_FOCUSED_EXIT=0. The complete log is attached. Final verify fast is now queued separately on compute01; current head b91728d3ba. Both hosts checked: dev-02 is free but the latest common brief (10:20 IST correction) excludes it as a merge-gate host due to privileged nf_tables environment failures. Attribution and trim receipts are attached here for preservation.

J337 gate finding, not yet attributed: workspace test row failed in infraternal-plugin-ssh --test install: 96 passed, 9 failed, 2 ignored. Seven failures report synthetic remote exit 73 or “Setup is already running”; two hit the existing 300-second INSTALL_HANG bound. Failed cases: earlier_binary_cache_is_refreshed_before_owned_recovery; earlier_control_socket_receipt_recovers_before_a_new_setup; known_failed_setup_finishes_without_a_second_confirmation; restart_recovers_partial_stage_retirement; review_restart_recovers_cleanup_after_base_retirement; review_restart_recovers_cleanup_after_owner_retirement; stale_previous_attempt_socket_can_be_retired_without_manual_cleanup; start_fresh_resumes_the_same_attempt_after_owner_confirmation; turning_off_paused_host_provisioning_preserves_earlier_leftovers.

The gate continues through all rows: shim feature tests passed (217/0/20), selected privileged install checks all 5 passed, release-probe exclusion passed, nightly-fuzz reporter checks passed. Static builds currently running. Full diagnostics: compute01 /home/claude/.cache/codex-scratch/J337/evidence/verify-fast.log, to be attached when complete. Do not count the gate as green. A focused unmodified-dev reproduction of these nine cases is prepared and will run in a separate slot after the gate ends. The production file-handler diff does not touch these paths, but baseline reproduction is still required before claiming an existing failure. Head unchanged: b91728d3ba.

Final gate result on b91728d3ba: VERIFY_FAST_EXIT=1. All rows passed except workspace tests (nine SSH install cases documented above). Static checks passed: x86 27,714,576 B, arm64 24,944,008 B; x86 exactly matches the measured cut. Full verify-fast.log is attached verbatim, alongside the section-layout validation receipts. Focused unmodified gate-base dev reproduction is queued separately; no regression/baseline conclusion yet.

J337 baseline reproduction is first in compute01 queue but blocked by the shared disk floor: 19 GB free / 25 GB required. No baseline test result yet. Gate log and exact summary are attached in comment 84255; every row passed except workspace tests (the nine install failures). To help capacity, preserved both shipping images and hashes under evidence/final-*, deleted our completed static/release target artifacts, then removed 215 completed debug test executables (26,537,369,096 B, receipt evidence/debug-executable-cleanup.json). Kept libraries and recovery helper for the focused reproduction. Other builds have since consumed the reclaimed space. No other jobs’ files touched. Remaining target is still the single J337 target; full removal follows the reproduction. Head unchanged b91728d3ba.

J337 final research report

Branch: size-trim-337. Head: b91728d3ba726b55b4ba0879701c441b5d8e7b3b. Base: 3644950b8e4b5dddeefba350f97a3892189ca193 (only decision-document changes after pinned research head). No merge, deploy, or baseline ratchet.

Matched builds on compute01, foreground build-slot, Nix launcher preflight, same toolchain and unchanged release profile: scripts/auth-toolchain then scripts/static-cargo build --locked --release --package infraternal --target x86_64-unknown-linux-musl -j4.

revision	stripped bytes
`a8926703ae`	22,419,344
`fba7450514`	27,787,280
retained cut	27,714,576

Growth: 5,367,936 B (+23.94%). Retained saving: 72,704 B. The stored 22,418,256 B D243 measurement came from 502d0fc7e; the requested a892 source measures 1,088 B larger in this matched run. No arm64 paired measurement is claimed.

The five isolated merges account for 4,474,560 B, 83.36% of the net growth:

merge	growth bytes
mesh SSH `5f156b8099`	2,266,144
Linux GotaTun `efbd863e2c`	871,584

key-rotation trust `363d954687`	380,544
API-key actions `8d3207cc84`	287,232

Full first-parent interval table follows. Multi-step rows are net interval totals, not individual-merge attribution; offsetting growth/shrinkage may exist inside them. Largest unresolved interval: 218,048 B. Historical broken commits were skipped without source patches: 7bbbd0e52 failed for missing proxy_containment initialization; da02013c8 and 990022655 were source-inspected unbuilt skips before fix 070c9a0b6.

The requested baseline a8926703a is the second parent of the first dev merge a479a8760; both have identical Git tree 56632d9009. The initial interval bridges that source-equivalent baseline onto dev; subsequent entries follow dev first parents. Multi-step rows are interval totals, not individual merge attributions.

Symbol attribution: the largest contributor is mesh SSH, not GotaTun. Parent/merge diagnostic images for both boundaries match all 24 allocated ELF sections against their shipping images. LTO symbol attribution does not equal a promised crate-removal saving.

Mesh SSH adds 1,684,044 B in text symbols: russh::server::reply (SharedAuthority) 62,912 B; ssh_key generic KeypairData signer 55,966 B; primeorder P256/P384/P521 basepoint setup 114,693 B combined; server_read_authenticated 38,210 B; MeshSshPlugin::push 34,852 B; EcdsaPublicKey::verify 33,139 B; SFTP packet codecs 42,322 B combined; serve_stream poll 21,422 B; MeshSshNode::call 21,157 B. See attached symbol-growth-5f156b80999c5afcb4a768f2cb7217dd653821d6.md.

GotaTun adds 691,487 B in text symbols: gotatun_node::run_worker 35,763 B; DeviceState::handle_incoming 29,461 B; PeerState::handle_incoming_packet 27,309 B; Engine::start 23,102 B; Connection::set_up task 19,995 B; UDP send task 16,533 B; initialize 13,445 B; timers 13,369 B; build_device 11,914 B; write_queued 7,980 B; handshake initiation 5,482 B. See attached symbol-growth-efbd863e2cc8ed064daa2c09bf11fbf0634aeb9d.md.

Retained cut: express the documented never-constructed NoFiles handler as an empty enum. Production open_files still returns Refusal::LoginAccess. Generic SFTP support and separate MemoryFiles fixtures remain. This removes unreachable production service code without changing runtime refusal, algorithm preferences, panic behavior, profile, dependencies, or baseline. Risk: constructor availability narrows to the existing invariant; workspace search found no constructor use. 27,787,280 → 27,714,576 B. Text symbols shrink 64,027 B; the two packet codecs shrink 23,821 + 18,501 B and unreachable subsystem body 9,032 B. Linked-code exclusion check changes from three NoFiles service symbols (red) to zero (green). All 24 allocated diagnostic sections match the trimmed shipping image.

Rejected paired cut: disabling tar default xattr in both declarations while preserving direct cgroup xattr grows the binary 64 B (27,787,280 → 27,787,344). Restored, not committed.

Audit: 37 dependency name-version pairs added, none removed; duplicate names 21 → 29. Both OpenSSL and rustls already existed at baseline. No Linux AWS-LC/native-tls was added; russh/GotaTun defaults are already disabled. Remaining crypto generations have live protocol uses. Removing NIST KEX changes supported negotiation; ssh-key encryption/PPK needs engine API changes. Generic signer specialization is a follow-up needing security/compatibility review, not a measured safe cut. Shipping is already stripped. Panic unwinding preserves task isolation; unwind section growth is 606,432 B. No opt-level/LTO change attempted. Details: attached cut-audit.md.

Verification and cleanup results follow below.

Final gate on retained head: VERIFY_FAST_EXIT=1, workspace test row FAIL (101); every other Rust row PASS. Full output is preserved verbatim in attached verify-fast.log; its final summary is quoted verbatim below. The static row confirms x86 27,714,576 B and arm64 24,944,008 B. Arm64 key-memory execution is explicitly skipped on x86. The nine failed SSH install cases did not reproduce in uninterrupted full install-suite reruns on unmodified gate-base dev 3644950b8 or retained head b91728d3b; both passed 105 tests with 2 ignored. The original full gate remains red; these reruns do not replace it, and the original failure cause is unproven. Origin/dev advanced during the gate to af033d0b4 (UI and SELinux login changes); these measurements and gate are for the stated branch/head, not that later dev revision.

VERIFY_FAST_EXIT=1

Focused validation receipts: quick passed every row and the changed-package unit suite (120 passed, 0 failed, 6 ignored). Existing real-engine mesh_requests_review (5), mesh_server (9), mesh_sftp (1), and mesh_stock_clients (1) all passed, including stock-client certificate exec/PTY/SFTP negotiation. QUICK_FOCUSED_EXIT=0; full log attached in comment 84122.

Gate failure follow-up on compute01, same target/toolchain/environment: rebuilt the recovery helper and ran cargo test --workspace --locked --test install -j4 on unchanged dev 3644950b8e4b5dddeefba350f97a3892189ca193, then separately on retained head. Both uninterrupted runs passed 105 passed, 0 failed, 2 ignored, including all nine original failures. Receipts: attached baseline-install-full.log (BASELINE_FULL_EXIT=0) and head-install-full.log (HEAD_INSTALL_FULL_EXIT=0). This does not establish that the full-gate failure exists on baseline; it did not reproduce. Cause remains unproven, and the full gate remains red pending orchestrator resolution. No unrelated test/setup code was changed. An earlier cancelled reproduction is excluded because cancellation restored the branch while its child was still running; its exit marker is not used as evidence. No work or target was started on dev-02.

Shipping images and hashes retained on compute01 under J337 evidence as final-x86_64-infraternal, final-aarch64-infraternal, and final-gate-images.sha256. Full build/symbol logs remain there; selected raw receipts and reports are attached to comments 84122 and 84255. Control mirror: /home/kayg/.cache/codex-scratch/J337/evidence/.

Cleanup: completed static/release artifacts and 215 completed debug executables (26,537,369,096 B) were removed to relieve shared disk pressure before the focused reruns. After both uninterrupted reruns, the remaining single target and private J337 test state were removed; evidence and worktrees retained. The discovered fixture shell/sleep pairs exited naturally before the exact-PID termination command reached them; both foreground SSH streams then closed. Final cleanup receipt attached. Control and VM branch are clean at pushed head b91728d3ba. Issue intentionally left open. No merge, deploy, or baseline ratchet.

See attached symbol-growth-efbd863e2cc8ed064daa2c09bf11fbf0634aeb9d.md. Retained cut: express the documented never-constructed NoFiles handler as an empty enum. Production open_files still returns Refusal::LoginAccess. Generic SFTP support and separate MemoryFiles fixtures remain. This removes unreachable production service code without changing runtime refusal, algorithm preferences, panic behavior, profile, dependencies, or baseline. Risk: constructor availability narrows to the existing invariant; workspace search found no constructor use. 27,787,280 → 27,714,576 B. Text symbols shrink 64,027 B; the two packet codecs shrink 23,821 + 18,501 B and unreachable subsystem body 9,032 B. Linked-code exclusion check changes from three NoFiles service symbols (red) to zero (green). All 24 allocated diagnostic sections match the trimmed shipping image. Rejected paired cut: disabling tar default xattr in both declarations while preserving direct cgroup xattr grows the binary 64 B (27,787,280 → 27,787,344). Restored, not committed. Audit: 37 dependency name-version pairs added, none removed; duplicate names 21 → 29. Both OpenSSL and rustls already existed at baseline. No Linux AWS-LC/native-tls was added; russh/GotaTun defaults are already disabled. Remaining crypto generations have live protocol uses. Removing NIST KEX changes supported negotiation; ssh-key encryption/PPK needs engine API changes. Generic signer specialization is a follow-up needing security/compatibility review, not a measured safe cut. Shipping is already stripped. Panic unwinding preserves task isolation; unwind section growth is 606,432 B. No opt-level/LTO change attempted. Details: attached cut-audit.md. Verification and cleanup results follow below. Final gate on retained head: **VERIFY_FAST_EXIT=1**, workspace test row FAIL (101); every other Rust row PASS. Full output is preserved verbatim in attached verify-fast.log; its final summary is quoted verbatim below. The static row confirms x86 27,714,576 B and arm64 24,944,008 B. Arm64 key-memory execution is explicitly skipped on x86. The nine failed SSH install cases did not reproduce in uninterrupted full install-suite reruns on unmodified gate-base dev 3644950b8 or retained head b91728d3b; both passed 105 tests with 2 ignored. The original full gate remains red; these reruns do not replace it, and the original failure cause is unproven. Origin/dev advanced during the gate to af033d0b4 (UI and SELinux login changes); these measurements and gate are for the stated branch/head, not that later dev revision. ```text +---------------------------+--------------+ | Rust gate | Result | +---------------------------+--------------+ | Nix Cargo vendoring | PASS | | fmt | PASS | | migration names | PASS | | migration tooling tests | PASS | | VT native fmt | PASS | | CLI plugin compile-out | PASS | | clippy | PASS | | SSH runtime test helper | PASS | | real-binary fixture paths | PASS | | Traefik component manifest | PASS | | release component publication | PASS | | test | FAIL (101) | | SSH inode reuse fixture | PASS | | shim process-per-user | PASS | | cargo-deny | PASS | | gate architecture | PASS | | doc coverage ratchet | PASS | | shape lints off (D351) | PASS | | doc comments on diff | PASS | | fixed test waits | PASS | | privileged integration | PASS | | probe release exclusion | PASS | | nightly fuzz reporter | PASS | | static builds | PASS | +---------------------------+--------------+ VERIFY_FAST_EXIT=1 ``` Focused validation receipts: quick passed every row and the changed-package unit suite (120 passed, 0 failed, 6 ignored). Existing real-engine mesh_requests_review (5), mesh_server (9), mesh_sftp (1), and mesh_stock_clients (1) all passed, including stock-client certificate exec/PTY/SFTP negotiation. `QUICK_FOCUSED_EXIT=0`; full log attached in comment 84122. Gate failure follow-up on compute01, same target/toolchain/environment: rebuilt the recovery helper and ran `cargo test --workspace --locked --test install -j4` on unchanged dev `3644950b8e4b5dddeefba350f97a3892189ca193`, then separately on retained head. Both uninterrupted runs passed **105 passed, 0 failed, 2 ignored**, including all nine original failures. Receipts: attached `baseline-install-full.log` (`BASELINE_FULL_EXIT=0`) and `head-install-full.log` (`HEAD_INSTALL_FULL_EXIT=0`). This does not establish that the full-gate failure exists on baseline; it did not reproduce. Cause remains unproven, and the full gate remains red pending orchestrator resolution. No unrelated test/setup code was changed. An earlier cancelled reproduction is excluded because cancellation restored the branch while its child was still running; its exit marker is not used as evidence. No work or target was started on dev-02. Shipping images and hashes retained on compute01 under J337 evidence as `final-x86_64-infraternal`, `final-aarch64-infraternal`, and `final-gate-images.sha256`. Full build/symbol logs remain there; selected raw receipts and reports are attached to comments 84122 and 84255. Control mirror: `/home/kayg/.cache/codex-scratch/J337/evidence/`. Cleanup: completed static/release artifacts and 215 completed debug executables (26,537,369,096 B) were removed to relieve shared disk pressure before the focused reruns. After both uninterrupted reruns, the remaining single target and private J337 test state were removed; evidence and worktrees retained. The discovered fixture shell/sleep pairs exited naturally before the exact-PID termination command reached them; both foreground SSH streams then closed. Final cleanup receipt attached. Control and VM branch are clean at pushed head b91728d3ba726b55b4ba0879701c441b5d8e7b3b. Issue intentionally left open. No merge, deploy, or baseline ratchet.

J346 starting on size-mesh-ssh-346, base fd0cbee18 (origin/dev). Plan: reproduce first-parent SSH merge static sizes and crate/symbol attribution; inspect negotiated algorithms and dependency features against D235/D289/D319; make only behavior-preserving feature/version cuts in atomic measured commits; run quick on dev-02, mesh/real-binary fixtures, cargo-deny and fast on compute01; report GotaTun/proxy candidates without changing them. Estimate: 4 hours including shared build queues. No merge or deployment. Evidence: ~/.cache/codex-scratch/j346/evidence on control host and compute01; one target per VM.

J346 finding: direct russh defaults are already disabled (ring only; no flate2/RSA/AWS-LC). Contrary to J337 cut-audit.md, SAFE_KEX_ORDER at both 5f156b809 and current dev does NOT include NIST ECDH; the full factory still registers/instantiates P256/P384/P521 ECDH. Candidate: opt-in feature-gate these never-advertised implementations, retain ECDSA key support and all current default negotiation names, and measure. This does not switch crypto implementations or change D235/D289/D319 authentication/access rules. Will verify both the factory exclusion and unchanged preferences plus stock-client fixtures.

J346 finding: the SSH merge itself changes NO Cargo manifests or Cargo.lock entries against first parent 19737d86d9. The 2,266,144 B step makes previously unlinked SSH engine/runtime paths live, rather than introducing 37 dependencies at that boundary. J337’s 21→29 duplicate-name count is a five-day endpoint comparison, not a per-SSH-merge dependency addition. Evidence: git diff 5f156b809^1 5f156b809 -- Cargo.toml crates/infraternal/Cargo.toml crates/infraternal-server/Cargo.toml crates/plugins/ssh/Cargo.toml is empty; compute01 ~/.cache/codex-scratch/j346/evidence/ssh-lock-diff.json records zero added/removed lock pairs. Initial dev-02 quick exited 0; the new red exclusion test fails precisely because ecdh-sha2-nistp256 is still registered, while the existing complete transport-offer test passes (red-algorithms.log).

J346 parent attribution completed: first parent 19737d86d9eac6d556d769ee6e4bb7457a4353a9 freshly reproduces 24,768,368 B with the pinned static release recipe on compute01. cargo bloat --crates used the same recipe through a child-cargo wrapper that retains only final-executable symbols (cargo rustc ... -- -C strip=none), avoiding cargo-bloat’s profile-wide strip override. All 24 allocated ELF sections match byte-for-byte between the new J346 shipping and diagnostic images. The helper initially pointed at J337 images; this was caught, corrected, and rerun against J346 images; validate-parent.log and the attached layout JSON are the corrected evidence. GNU strip changes only non-allocated metadata by -8 B, not a saving. Initial dev-02 quick exited 0; the red test fails precisely on registered NIST ECDH. Raw receipts attached. SSH merge attribution is queued (PID 3648899), with no other J346 slot held. One compute01 target: /home/claude/worktrees/j346/target.

J346 checkpoint: head 4a953627e on size-mesh-ssh-346. Three isolated WIP cuts are pushed: unoffered NIST ECDH, AES-CBC/AES128-GCM transport factories, and legacy SHA-1/none transport factories. No backend or offered algorithm change. Red linkage receipts find 39 AES-CBC transport symbols and 9 SHA-1 transport symbols in the historical SSH image. These commits are explicitly unmeasured and not ready to merge.

Fresh parent attribution reproduces 24,768,368 B with all 24 allocated sections matching the diagnostic image. The SSH-merge cargo-bloat build is running in compute01 slot 1, PID 3648899; log /home/claude/.cache/codex-scratch/j346/evidence/attribute-merge.log. Next: complete crate/symbol deltas, then measure each cut and run green compatibility/quick/fast gates. One target per VM: /home/claude/worktrees/j346/target.

J346 finding: same-profile attribution complete for 5f156b809 versus first parent 19737d86d. Shipping size 24,768,368 -> 27,034,512 B, +2,266,144 B. Fresh cargo-bloat diagnostic builds match all 24 allocated sections of each shipping image. GNU strip is 8 B smaller in nonallocated metadata; that is not claimed as a saving.

Leading section deltas: text +1,691,224; data +197,856; rodata +102,400; data.rel.ro +33,184; unwind/exception sections +239,988 B. Crate attribution is text only and heuristic under LTO; it does not assign the full file delta to crates. Leading text deltas: infraternal_plugin_ssh +316,320; russh +315,875; ssh_key +180,466; infraternal_server +160,228; aes +58,673; num_bigint +54,665; russh_sftp +52,734; curve25519_dalek +32,579; sha2 +30,469; primeorder +20,302; ecdsa +19,203; crypto_bigint +17,009; ssh_encoding +16,771; p521 +14,368; p384 +12,519; p256 +10,426; ed25519_dalek +9,329; ml_kem +7,628. OpenSSL text delta is zero, ring +860 B.

The merge changes no Cargo manifests or lockfile package/version pairs. It makes existing SSH code live. Russh already has defaults disabled and only its ring feature enabled: no AWS-LC, RSA feature or SSH compression. Big integers remain for the advertised SHA-2 finite-field DH exchanges, so they cannot be treated as removable RSA. Key decoding/signing, certificates, ECDSA and SFTP are material contributors. The ring feature does not replace every RustCrypto implementation; switching those primitives is outside J346's authorization. The parent already has 29 duplicated production crate names; its version splits are incompatible semver generations, not candidates for a compatible cargo-update unification.

Evidence attached: paired cargo-bloat delta, deduplicated symbol diff, merge bloat output, allocated-section equivalence and attribution run log. Full parent/merge JSON and nm receipts remain under /home/claude/.cache/codex-scratch/j346/evidence on compute01.

Current branch head 2870bad73 is rebased onto dev 21b3c84ce. Quick initially found the removed ECDH feature needs a lockfile refresh (unused hkdf 0.13 removed); that fix is now in the first atomic WIP cut. Changed quick is running on dev-02. Cuts remain unmeasured and not merge-ready.

J346 later candidates, no cuts made here:

GotaTun merge efbd863e2: +871,584 shipping B, including +697,401 text B (retained J337 paired images). In the freshly measured pre-SSH image, gotatun owns 404,390 text B and the shared mesh plugin 870,093 B. Supporting crate footprints: blake2 12,523; poly1305 7,559; chacha20 5,242; chacha20poly1305 2,551 B. Retained paired symbols show the new mesh worker loop +35,763, engine start +23,102, device receive path +29,461, peer incoming handling +27,309 and connection setup +19,995 B. Candidate work: inspect the mesh worker/device task and packet-path specializations, preserving the owner-selected engine and algorithms. These shared whole-crate footprints are not the attributable merge delta or removable savings.
Reverse-proxy merge 91112e9da: +669,056 shipping B, including +563,872 text B (retained paired section receipts). Fresh pre-SSH crate footprints: infraternal_plugin_proxy 269,248; miniz_oxide 15,038; tar 14,076; flate2 7,838; crc32fast 3,696; xattr 3,195 B. Candidate work: inspect proxy orchestration and archive/install reachability. No claim that these entire shared footprints are removable, and no proxy or GotaTun code changed in J346.

The footprint basis is J346's same-profile cargo-bloat of 19737d86d, after both merges and before SSH. An isolated crate-by-crate attribution for these older boundaries would require additional historical builds; the figures above deliberately distinguish retained per-merge section/symbol deltas from current whole-crate text footprints.

Static x86 measurement batch 1 is queued on compute01, PID 4151882: current dev then NIST-ECDH cut d06f3bfc4. Log /home/claude/.cache/codex-scratch/j346/evidence/measure-cuts-1.log. Subsequent AES/legacy cuts will use a separate slot run. No second J346 slot is held. Final full gate and real-binary SSH fixtures remain pending; branch is still WIP.

J346 measurement scheduling update: compute01 queue remained deep, so queued PID 59351 was cancelled before acquiring a slot. Per the task's allowed dev-02 option, paired x86 musl measurements now run on dev-02 through build-slot, j3, unchanged static profile and scripts/static-cargo recipe. PID 3767324 has acquired its slot and is building base 21b3c84ce then cut d06f3bfc4. Log /home/claude/.cache/codex-scratch/j346/evidence/measure-cuts-1.log on dev-02. Comparison will be within the same host; final compute01 gate sizes will be reported separately. Final verify fast remains on compute01 as requested. Only one J346 slot held.

J346 second measured cut: unoffered AES transport factories, 0e71f907a. Same-host dev-02 x86 musl static release, unchanged profile/backend: 27,769,008 -> 27,723,088 B, saving 45,920 B. The batch has advanced to the legacy-transport cut. Partial receipt attached with both source hashes and the completed AES image hash; final batch exit is still pending.

AES128/192/256-CBC and AES128-GCM transport factories are excluded. All five advertised ciphers, initial clear transport and key-file CBC support remain. Earlier changed quick and 28-test mesh compatibility suite pass, including stock-client certificate exec/PTY/SFTP. Cumulative measured saving so far: 75,936 B. No advertised algorithm removed.

Attached provenance verifies identical source trees between all measured checkpoints and their finalized commits. Attached ELF validation confirms all four dev-02 measurement images are stripped x86-64 static PIEs, with no PT_INTERP and no DT_NEEDED.

This matches the earlier dev-02 compatibility receipt. The previous-attempt shell matrix completed after its >60s notice and the gate advanced normally.

J346 gate finding, not a green gate: the full workspace test row failed four enrollment cases. Every failure is PoolTimedOut at crates/infraternal-server/tests/enrollment.rs:42, the fixture's initial SqlitePoolOptions::connect_with await, before migrations or enrollment assertions. Four cases failed together; the fifth live case passed. Exact failure block attached.

The branch changes no enrollment/server source or database crate versions. This is not yet proven to reproduce on baseline, and no cause or fix is claimed. After the current gate exits, a prepared short slot run will execute the full enrollment integration target with workspace features and four test threads, first on unchanged dev 21b3c84ce, then on head 335cde8e1, same target/toolchain/environment. No checkout while the current gate has live children, and no speculative fixture or timeout edits.

The current gate continues its later rows so their results and shipping images are preserved. Full log /home/claude/.cache/codex-scratch/j346/evidence/verify-fast.log on compute01; PID 239544. Mesh compatibility remains green on both hosts (28 focused tests each). Real-binary SSH fixtures and enrollment reproductions remain pending; final head stays 335cde8e18.

J346 enrollment comparison: unchanged base 21b3c84ce and final head 335cde8e1 each passed all five live enrollment tests (one ignored), same target/toolchain, workspace features and four test threads. ENROLLMENT_EXIT=0 in each attached log. The original full-gate PoolTimedOut failure is unreproduced, not a proven baseline failure and not a green gate. No enrollment code or timeout changes.

The stock real-binary session fixture failed waiting for shim-test, before its handover assertions. Environment evidence: claude passwd shell is /bin/bash, while that readiness marker is supplied by a .zshrc; /home/claude/worktrees is also group-writable, so the shim correctly refuses that ZDOTDIR ancestor. No production security policy is being weakened. A scratch driver replaces only readiness with an explicit printf through the actual shell, retaining all existing session/writer/replay and single-shell assertions. It is queued through build-slot, PID 4097916, log /home/claude/.cache/codex-scratch/j346/evidence/real-ssh-native-shell.log. Initial failing fixture log and exact scratch driver attached for audit.

Head stays 335cde8e18. origin/dev advanced during the gate with the macOS SOCK_CLOEXEC fix (6b1bdb81b); the measured/tested branch base remains 21b3c84ce, refreshed before the original final gate. No merge/deploy.

J346 real-binary session fixtures passed with the explicit native-shell readiness canary described in 84787/84788. All original assertions run against the unmodified x86 shipping binary: shim-owned early shell, same session/writer across transport retry and handover, pending input exactly once, resumed output, and exactly one live shell on rebridge. REAL_NATIVE_SHELL_EXIT=0, full log attached. The original unadapted fixture failure remains preserved; no production code or security policy changed to accommodate this VM shell.

A separate full verify fast retry at the same head 335cde8e18 has now started on compute01 (PID 549109; log /home/claude/.cache/codex-scratch/j346/evidence/verify-fast-retry.log). Both slot statuses checked, compute01 had a free slot, launcher cargo 1.99.0. The first red gate remains attached in 84723, and enrollment passed on both base and head in 84787; the original timeout remains unreproduced. No merge/rebase/deploy or extra source changes.

J346 second full gate workspace test failure: five SSH install recovery cases failed (102 passed, 5 failed, 2 ignored), with synthetic remote exit 73 / SetupRunning. Exact failures attached. These cases passed in the first full gate; the branch changes no installer/recovery code. They use local synthetic commands, not mesh SSH negotiation. No cause or baseline reproduction is claimed yet. After the current gate and children exit, a prepared short slot run will compare the full install integration target at unchanged base 21b3c84ce and head 335cde8e1 with four test threads. No checkout while this gate is active, and no speculative installer edit.

The second gate continues its remaining rows; log /home/claude/.cache/codex-scratch/j346/evidence/verify-fast-retry.log, PID 549109. Real-binary session/rebridge assertions passed with the documented explicit shell-readiness canary (84826). Both gate failures remain recorded, with no green full gate claim.

J346 second compute01 full gate finished exit 1. All rows except workspace tests passed, including cargo-deny, all 101 privileged cases and both static builds. Failure is the five synthetic install recovery cases documented in 84855. No green full gate claim. The x86 image remains exactly 27,705,552 B. Full log attached.

The install base/head comparison is now queued on compute01, PID 1188876, log /home/claude/.cache/codex-scratch/j346/evidence/install-repro-batch.log. Both slot statuses checked; same compute01 target/environment retained for a causal comparison. dev-02 target was already cleaned and its slot is busy. No other J346 heavy work is running. Head remains 335cde8e18.

J346 final implementation handoff, 22:45 IST. Branch size-mesh-ssh-346, pushed head 335cde8e18, measured/tested base 21b3c84ced. Worktrees are clean. No merge, deployment or issue closure.

Measured cuts, separate atomic commits:

commit	cut	before B	after B	saved B
`d5741392e`	unoffered NIST ECDH	27,799,024	27,769,008	30,016
`79f519659`	unoffered AES transport	27,769,008	27,723,088	45,920
`335cde8e1`	unoffered legacy transport	27,723,088	27,702,896	20,192
total		27,799,024	27,702,896	96,128

These are paired dev-02 x86 musl shipping builds with unchanged static profile/backend. Measurement logs, ELF validation and identical-tree provenance are attached in 84525/84571. Native compute01 final/retry images are both 27,705,552 B x86 and 24,934,128 B arm64; their hashes are unchanged between gates. Do not substitute those native absolute sizes into the dev-02 paired delta.

Attribution: SSH merge 5f156b809 vs first parent 19737d86d is +2,266,144 B; cargo-bloat and symbol diff are attached in 84465. Largest attributed text increases are SSH plugin +316,320, russh +315,875, ssh_key +180,466, server +160,228, AES +58,673, num_bigint +54,665 and russh_sftp +52,734 B. LTO crate attribution is heuristic and text-only. Correction to the earlier prose: the Rust openssl crate is +868 B, not zero, as its attached table already shows; ring is +860 B. The merge introduces no manifest or lockfile package/version pairs: it makes existing code reachable. Russh already used defaults off plus ring, with RSA and compression off. No production rsa crate; num-bigint 0.5 supports live DH, while 0.4 comes through der-parser. No compatible duplicate-version unification was available, and no primitive backend was replaced.

Negotiation/security: no advertised algorithm changed. KEX remains mlkem768x25519-sha256, both Curve25519 names, GEX-SHA256, groups 18/17/16/15-SHA512 and group14-SHA256, plus role extension/strict markers. Ciphers remain chacha20-poly1305, AES256-GCM and AES256/192/128-CTR; MACs remain SHA2-512/256 and their ETM forms; compression none; server host keys Ed25519 certificate/plain. The removed factories were unoffered NIST P-256/384/521 ECDH; AES128/192/256-CBC and AES128-GCM transport; GEX/group1/group14-SHA1, none KEX and SHA1/SHA1-ETM MACs. ECDSA signing/verification, key-file encryption, hashed known-host support and the internal clear/AEAD machinery remain. D235/D289/D319 behavior is preserved.

Checks: dev-02 changed quick passed; 28 focused mesh SSH tests passed on both hosts, including stock-client certificate exec/PTY/SFTP and on-wire offer snapshots. Real-binary session/rebridge assertions passed with the documented explicit bash readiness canary (84826); the unadapted zsh-prompt fixture failure remains preserved (84787/84788). Cargo-deny, privileged integration (101/101), static builds and every non-workspace-test gate row passed in both full compute01 runs. The inode-reuse row could not induce reuse after 256 attempts and ignored that environment-dependent case.

Full gate remains red. First run: four enrollment initial-pool timeouts; enrollment then passed on both base and head (5 live tests each). Second run: five synthetic install recovery failures; the entire install target now passed on both base and head (107 passed, 0 failed, 2 ignored each, INSTALL_EXIT=0). Those exact comparison logs are attached here. Neither failure reproduced; no root cause or proven baseline failure is claimed. No speculative installer/database edits were added. Orchestrator: please scope a separate fixture-instability investigation (45–90 minute estimate) if needed before integration; the common brief's scope leash requires asking before expanding into unrelated fixture work. A green full gate remains the blocker.

Later candidates only: GotaTun merge +871,584 B: gotatun 404,390 B text and shared mesh plugin 870,093, with blake2/poly1305/chacha20 contributions. Reverse-proxy merge +669,056 B: proxy plugin 269,248 B, miniz_oxide 15,038, tar 14,076, flate2 7,838, crc32fast 3,696, xattr 3,195. These are retained whole-crate footprints, not isolated merge deltas or removable savings; exact section/symbol evidence is in 84478. Neither area was cut.

Cleanup: no J346 binary/fixture processes remain and no J346 work is queued/running. compute01 target (44G) and private fixture state removed; dev-02 target removal independently rechecked. Evidence and shipping images retained outside targets at /home/claude/.cache/codex-scratch/j346/evidence/; cleanup receipts attached. origin/dev advanced during the gate with the macOS SOCK_CLOEXEC fix (6b1bdb81b); no silent rebase changed this measured head.

Final full-gate output, verbatim (complete logs attached in 84723 and 84873):

A green full gate remains the blocker. **Later candidates only:** GotaTun merge +871,584 B: gotatun 404,390 B text and shared mesh plugin 870,093, with blake2/poly1305/chacha20 contributions. Reverse-proxy merge +669,056 B: proxy plugin 269,248 B, miniz_oxide 15,038, tar 14,076, flate2 7,838, crc32fast 3,696, xattr 3,195. These are retained whole-crate footprints, not isolated merge deltas or removable savings; exact section/symbol evidence is in 84478. Neither area was cut. **Cleanup:** no J346 binary/fixture processes remain and no J346 work is queued/running. compute01 target (44G) and private fixture state removed; dev-02 target removal independently rechecked. Evidence and shipping images retained outside targets at `/home/claude/.cache/codex-scratch/j346/evidence/`; cleanup receipts attached. origin/dev advanced during the gate with the macOS SOCK_CLOEXEC fix (6b1bdb81b); no silent rebase changed this measured head.

J353 checkpoint: source review found no correctness/security regression so far. The J337 cut is the uninhabited NoFiles type (not a crypto cut); production open_files remains LoginAccess. J346 removes only factories absent from the unchanged preferences, and negotiation intersects preferences rather than the factory catalogue; internal clear/NONE and ECDSA remain. Runtime/size verdicts are pending, not assumed. Compute01 launcher preflight passed, queue wait was about 16 minutes, and PID 1836755 now holds one slot for the pinned-dev focused run. Helper built successfully; suite targets are compiling. Evidence: /home/claude/.cache/codex-scratch/J353/evidence/, one target /home/claude/worktrees/J353/target. Scratch harness captures both KEXINIT directions over TCP and authenticates against the production authority, including a stock ssh client, production SFTP refusal, every advertised KEX fallback and all cipher/MAC pairings. Still to do: finish 3 runs per suite per revision, branch capture diffs, matched original-base/head static builds, report and cleanup. No full gate rerun, no live mesh claim, no merge/deploy/push.

J353 runtime checkpoint, no final verdict until paired sizes finish. Pinned dev 6b1bdb81b: enrollment 3/3 clean (5 passed, 1 ignored each); install 3/3 clean (107 passed, 2 ignored each). J337 b91728d3b: enrollment 3/3 clean (5 passed, 1 ignored each); install 3/3 clean (105 passed, 2 ignored each). No failed suite run in either revision. J337 completed all 31 TCP handshake configurations against the production Authority and mesh_server: stock ssh, default, every advertised KEX, and every cipher/MAC pairing. All 62 ordered peer-offer files match dev exactly (ten name-lists plus flags/reserved). Direct production open_files returns LoginAccess and authenticated SFTP gets SSH_MSG_CHANNEL_FAILURE throughout. Existing mesh_server, mesh_startup and stock-client exec/PTY/SFTP tests also passed. This does not turn the authors' red full gate green or prove its original cause. J346 focused checks are queued, PID 2815161. Same one target and evidence directory; no live mesh claim. Attached J337 phase evidence includes raw initial SSH packets, normalized lists, harness results and the three suite logs. Dev receipts remain at /home/claude/.cache/codex-scratch/J353/evidence/dev-* and the control mirror. Full raw-packet decoder comparison and static-profile base/head builds are still pending.

J353 checkpoint: all requested enrollment/install repeats have finished clean, three per suite on each exact head and pinned dev (18 suite runs, zero failed suite runs). Install: dev 107/0/2, J337 105/0/2, J346 107/0/2 passed/failed/ignored per run. Enrollment: 5/0/1 per run throughout. Both branches completed the 31-case TCP handshake sweep and all 62 peer-offer files per branch compare equal to dev; production LoginAccess and authenticated SFTP channel-failure behavior is unchanged. J346 registry/ECDSA and existing mesh suites passed. Source and runtime evidence remain on compute01, /home/claude/.cache/codex-scratch/J353/evidence/; phase archives are mirrored on control. Original full gates remain red; no full-gate pass or original cause is inferred.

Both slot statuses were checked after focused tests: dev-02 was free while compute01 was busy. Removed the completed compute01 target, preflighted cargo in the exact Nix launcher on dev-02, and moved only the requested same-host static measurement there (CARGO_INCREMENTAL=0, -j3, one target /home/claude/worktrees/J353/target). J337 matched original-base/head pair finished: 27,779,344 -> 27,706,640 B, saving exactly 72,704 B. These dev-02 absolute sizes are not substituted into the authors' native measurements. J346 base build finished and exact head is building, PID 1144842. Receipts/images: dev-02:/home/claude/.cache/codex-scratch/J353/evidence/. No compute01 J353 work remains queued/running. Remaining: finish J346 pair; independent raw-packet decode and profile/ELF receipt validation; final verdict comment and cleanup. No repository changes, merge, deploy or push.

J353 independent correctness/security review: APPROVE both branches. No correctness or security findings in the reviewed changes.

APPROVE size-trim-337 at b91728d3ba726b55b4ba0879701c441b5d8e7b3b.
APPROVE size-mesh-ssh-346 at 335cde8e18dfc272a2767686c655128c4a58eeea.

Pinned comparison dev: 6b1bdb81b3d8eb90716643e7d1bd03f61ce37827. Read the common brief, CLAUDE.md, architecture/process, D243/D235/D289/D319, reports 84315/84896, and the original failed gate logs. Scope clarification: J337 makes the never-constructed production NoFiles type uninhabited; J346 removes unoffered transport factories.

1. Negotiation and security: unchanged.

Built and exercised each exact revision on compute01. The isolated TCP fixture uses the production mesh_authority::Authority, mesh_server::config plus a host certificate (the same assembly as mesh_node), and mesh_server::serve. It relays actual SSH bytes, captures the initial KEXINIT in both directions, completes certificate authentication, then observes the production file refusal. No live unit, interface or deployment was changed.

Each revision completed 31 handshake configurations: default, the host's actual ssh client, all nine advertised KEX algorithms, and all five cipher/four MAC pairings. This includes every finite-field fallback and all 12 CTR/SHA-2 MAC combinations. Existing mesh server, startup/rekey/optimistic fallback, and stock-client certificate exec/PTY/SFTP suites also passed on all three revisions. J346's registry exclusion and P-256/P-384/P-521 ECDSA signing/verification checks passed.

Independent Python decoding of the raw initial SSH packets confirms 62 peer offers per branch compared with dev, zero differences. All ten ordered name-lists, first-kex-packet-follows and reserved fields match. Random cookies and packet padding are excluded from the semantic diff, and retained in the raw packets. Both trim-wire.diff and mesh-wire.diff are empty. Stock-client negotiated algorithms are also identical: ML-KEM/X25519, Ed25519 host certificate, chacha20-poly1305, no compression.

The server offer remains:

KEX: mlkem768x25519-sha256; both Curve25519 names; GEX-SHA256; groups 18/17/16/15-SHA512; group14-SHA256; server extension/strict markers.
Host keys: Ed25519 certificate, then plain Ed25519.
Both cipher directions: chacha20-poly1305, AES256-GCM, AES256/192/128-CTR.
Both MAC directions: SHA2-512/256 ETM, then SHA2-512/256.
Both compression directions: none; languages empty.

Source review confirms selection intersects the unchanged preferences, rather than falling back through the factory catalogue. Removed-but-known names becoming unknown still preserve optimistic first-choice accounting. Internal clear/NONE machinery, ECDSA, key-file encryption and hashed-known-host support remain. The sole production russh consumer still uses defaults off plus ring. No foundational engine/backend/profile choice changed.

Evidence: j353_wire.rs, focused.sh, report.py, {dev,trim,mesh}-wire/, the three *-raw-decoded.json files, *-wire-tests.log, source-audit.md/log, and final-verification.log in the attached bundle.

2. J337 production refusals: unchanged.

On dev and both heads, an authorized production guard returns exactly Err(Refusal::LoginAccess) from open_files. After successful real SSH certificate authentication, the SFTP request receives SSH_MSG_CHANNEL_FAILURE; no file handler is constructed. The existing separate in-memory file-runtime tests still negotiate and transfer SFTP successfully, so generic SFTP support remains. The workspace has no construction of production NoFiles; its constructor availability narrows to the documented invariant. The error/refusal path and panic/unwind policy are unchanged.

3. Byte savings: both reproduce exactly.

Matched original-base/head pairs, all on dev-02, with the exact Nix cargo launcher preflighted before queueing, one build slot, nice -n10, CARGO_INCREMENTAL=0, -j3. Recipe: scripts/auth-toolchain, then scripts/static-cargo build --locked --release --package infraternal --target x86_64-unknown-linux-musl -j3.

branch	original base	base bytes	head bytes	saved
size-trim-337	`3644950b8e4b5dddeefba350f97a3892189ca193`	27,779,344	27,706,640	72,704 B
size-mesh-ssh-346	`21b3c84ceddd571e1580f679009860e32b37beb9`	27,799,024	27,702,896	96,128 B

Compiler versions, complete profile JSON and static compiler/config script fingerprints match within each pair. The unchanged profile retains LTO, one codegen unit, stripping, unwind, and existing package optimization overrides. All four images are stripped x86-64 static PIEs, with no PT_INTERP or DT_NEEDED. These paired dev-02 absolutes are not mixed with earlier native compute01 measurements. No combined/additive saving is claimed.

Evidence: all four *-static-{build,provenance,receipt}.log groups, launcher/host logs, static-image-hashes.log, static.sh, pair.sh, and review-summary.json/txt. Actual images remain outside targets on dev-02 at /home/claude/.cache/codex-scratch/J353/evidence/{trim-base,trim,mesh-base,mesh}-static-image.

4. Red-gate follow-up: zero failed runs in the requested matrix.

For each exact revision, rebuilt its recovery helper, then ran cargo test --workspace --locked --test enrollment --test install --no-fail-fast -j4 three times, without forcing serial test execution and using the same compute01 target/environment. No fixture or production test source was changed. --no-fail-fast ensures both suites run even if one fails.

revision	enrollment runs failed / total	enrollment per run (pass/fail/ignore)	install runs failed / total	install per run (pass/fail/ignore)
dev `6b1bdb81b`	0/3	5/0/1 each	0/3	107/0/2 each
J337 `b91728d3b`	0/3	5/0/1 each	0/3	105/0/2 each
J346 `335cde8e1`	0/3	5/0/1 each	0/3	107/0/2 each

All nine cargo commands exit 0: 18 suite runs, zero failed suite runs. The historical failures did not reproduce. This does not establish their root cause, prove a baseline full-gate failure, or recreate full-workspace contention. It does not make the original full gates green. Per the common brief's reviewer rule, I ran focused tests rather than verify quick/fast; the orchestrator still owns the integration gate.

Evidence: {dev,trim,mesh}-suites-{1,2,3}.log, helper/provenance logs and review-summary.json/txt. Original raw gates remain attached in comments 84255, 84723 and 84873.

Recipe: `scripts/auth-toolchain`, then `scripts/static-cargo build --locked --release --package infraternal --target x86_64-unknown-linux-musl -j3`. | branch | original base | base bytes | head bytes | saved | |---|---|---:|---:|---:| | size-trim-337 | `3644950b8e4b5dddeefba350f97a3892189ca193` | 27,779,344 | 27,706,640 | **72,704 B** | | size-mesh-ssh-346 | `21b3c84ceddd571e1580f679009860e32b37beb9` | 27,799,024 | 27,702,896 | **96,128 B** | Compiler versions, complete profile JSON and static compiler/config script fingerprints match within each pair. The unchanged profile retains LTO, one codegen unit, stripping, unwind, and existing package optimization overrides. All four images are stripped x86-64 static PIEs, with no PT_INTERP or DT_NEEDED. These paired dev-02 absolutes are not mixed with earlier native compute01 measurements. No combined/additive saving is claimed. Evidence: all four `*-static-{build,provenance,receipt}.log` groups, launcher/host logs, `static-image-hashes.log`, `static.sh`, `pair.sh`, and `review-summary.json/txt`. Actual images remain outside targets on dev-02 at `/home/claude/.cache/codex-scratch/J353/evidence/{trim-base,trim,mesh-base,mesh}-static-image`. **4. Red-gate follow-up: zero failed runs in the requested matrix.** For each exact revision, rebuilt its recovery helper, then ran `cargo test --workspace --locked --test enrollment --test install --no-fail-fast -j4` **three times**, without forcing serial test execution and using the same compute01 target/environment. No fixture or production test source was changed. `--no-fail-fast` ensures both suites run even if one fails. | revision | enrollment runs failed / total | enrollment per run (pass/fail/ignore) | install runs failed / total | install per run (pass/fail/ignore) | |---|---:|---|---:|---| | dev `6b1bdb81b` | 0/3 | 5/0/1 each | 0/3 | 107/0/2 each | | J337 `b91728d3b` | 0/3 | 5/0/1 each | 0/3 | 105/0/2 each | | J346 `335cde8e1` | 0/3 | 5/0/1 each | 0/3 | 107/0/2 each | All nine cargo commands exit 0: **18 suite runs, zero failed suite runs**. The historical failures did not reproduce. This does not establish their root cause, prove a baseline full-gate failure, or recreate full-workspace contention. It does not make the original full gates green. Per the common brief's reviewer rule, I ran focused tests rather than `verify quick/fast`; the orchestrator still owns the integration gate. Evidence: `{dev,trim,mesh}-suites-{1,2,3}.log`, helper/provenance logs and `review-summary.json/txt`. Original raw gates remain attached in comments 84255, 84723 and 84873.

All captures, logs, decoder/reproducer scripts, source diffs and cleanup receipts are attached in `J353-review-evidence.tar.gz`. Control mirror: `/home/kayg/.cache/codex-scratch/J353/evidence/`. Runtime originals remain on compute01 under `/home/claude/.cache/codex-scratch/J353/evidence/`; static originals/images remain at the same path on dev-02. Cleanup verified: both J353 targets removed, private test state removed, zero remaining J353 fixture/worktree processes, no J353 heavy work queued/running. Worktrees/evidence retained. No repository code changed, no merge/deploy/push, issue left open. **Final verdicts: APPROVE b91728d3ba726b55b4ba0879701c441b5d8e7b3b; APPROVE 335cde8e18dfc272a2767686c655128c4a58eeea.** Evidence downloads: [J353-review-evidence.tar.gz](https://git.kayg.org/attachments/20679c42-1d4c-4db2-b715-d9b0bd9b59e6), [J353-review-summary.txt](https://git.kayg.org/attachments/56ebc519-36e2-4eda-adc5-0d86de1b1e40).
