Owner 2026-10-12: start cutting size; never rebaseline upwards. Live
1f77a449: x86 20,093,808 B / arm 17,910,064 B. deve4942e4c: ~21.7 MB / 19.2 MB. Gate max still 16,404,816 / 13,817,816. Job: size-cut.Starting on branch size-cut from base
e4942e4c1f. Issue #175 has no prior comments and no parent issue is referenced in its body.Finding:
cargo tree --locked --package infraternal --target x86_64-unknown-linux-musl -d --edges normalshows duplicate production versions: base64 0.21.7/0.22.1, rand 0.8.8/0.9.5/0.10.3, thiserror 1.0.69/2.0.21, and syn 2.0.119/3.0.6. The routes split across WebAuthn, Quinn, and CLI/macro dependencies inCargo.lock; no safe direct unification is established yet, so none is changed.Finding: the #57 baseline commit
ac03b191has nocrates/infraternal-shim/build.rsand keepslibghostty-vtoptional; currentcrates/infraternal-shim/build.rsbuilds and links it in production. The pinned x86_64 static archive in this run is 16,166,236 bytes. This is a likely growth source; the shipped binary section contribution is pending the current link and bloat report. I will measure the existing engine build mode before considering any change.Completed x86_64 musl baseline at
e4942e4c: stripped static PIE is 21,709,776 bytes, +5,567,104 versus the #57 measurement (16,142,672).size -Areports .text 16,674,607 B, .rodata 1,867,248 B, .data.rel.ro 887,352 B, and .data 55,824 B; PT_INTERP is absent. SHA-256: d074ff3e9a1b69017ba14ae38024985054a828c59a89eaf90c24bc490426bd32.cargo bloatattribution is still rebuilding its unstripped diagnostic artifact.Completed x86
cargo bloatattribution (--release --target x86_64-unknown-linux-musl -p infraternal):infraternal_serveris 2.5 MiB of .text versus 501.9 KiB in #57;[Unknown]is 3.5 MiB, including Ghostty symbols such asterminal.osc.Parser.end(35.0 KiB),terminal.stream_terminal.Handler.apcEnd(28.7 KiB), andterminal.PageList.resizeCols(18.8 KiB). Other current large crates areopenssl_sys1.9 MiB,infraternal_plugin_mesh503.6 KiB,quinn_proto431.4 KiB,infraternal_agent363.9 KiB, andinfraternal_plugin_ssh204.6 KiB. The top two OpenSSL AES-GCM AVX-512 symbols are 329.7 KiB each (659.4 KiB combined).cargo bloatmarks these as estimates. Full crate and top-100-symbol tables are being recorded indocs/verification/size-175.md.Finding: the x86 feature-off matrix measures the
remotegroup at 17,922,432 B versus 21,709,776 B with defaults, a 3,787,344 B delta. The feature is required and will remain enabled; this is attribution only. The delta is non-additive with other feature groups.Finding: disabling the
sshfeature group (including its impliedplugin-ssh) produces a 21,060,464 B x86 binary, 649,312 B below defaults. This is attribution only; SSH remains enabled per the no-feature-removal constraint.Completed x86_64 feature-off attribution at
e4942e4c(default binary 21,709,776 B): release -242,560 B; remote -3,787,344 B; SSH plus implied plugin-ssh -649,312 B; host-facts -61,888 B; backup -7,264 B; mesh -1,329,984 B; relay -7,264 B. Each variant disables one group from the same default set and is independently linked, so deltas are not additive. Server/agent support features are transitively required by other groups. Product capabilities remain enabled.Finding: the experimental ReleaseSmall native archive is 1,963,286 B versus the existing ReleaseFast archive at 16,166,236 B (14,202,950 B smaller). This archive-level change is only a candidate: final linked x86/arm sizes and PTY echo performance are pending before acceptance.
Rejected the ReleaseSmall trial and reverted
scripts/build-vt: linked x86 size fell 21,709,776 -> 21,104,528 B (605,248 B saved), but real PTY same-session flood echo p99 across 3 interleaved 100-sample runs was 624.86/474.80/425.83 ms before versus 690.90/735.86/848.00 ms after (median 474.80 -> 735.86 ms). Host load ranged about 35–66, so the result is noisy, but the consistent same-session regression fails D243's hot-path bar. No trial change is retained.Rejected the
clap_builderopt-levelstrial: x86 size fell by 78,272 B, but three interleaved server-startup samples had median readiness 373 ms before versus 786 ms after (RSS medians 11,853,824 B versus 11,911,168 B). Host load ranged about 31–52 and the individual candidate times varied from 123 ms to 2,029 ms, so neutral startup latency was not established. The Cargo profile override is being removed.Cold action profile trial (
infraternal-plugin-releaseandinfraternal-plugin-host-facts, opt-levels): x86 stripped size 21,709,776 -> 21,538,736 B (171,040 B smaller). Three local interleaved server runs undersystemd-run --user --scope -p CPUWeight=10000had startup readiness median 566.81 -> 501.26 ms and idle RSS median 13,459,456 -> 13,664,256 B; load at start was 1/5/15-minute 15.82/30.25/39.96. Real PTY no-flood and other-session echo passed on both; same-session flood failed on both, with median PTY echo p99 46.12 -> 47.63 ms (+1.51 ms). This points to a neutral terminal path under host load, while the same-session gate remains red for both binaries.Completed aarch64-unknown-linux-musl baseline at
e4942e4cwith the original release profiles: stripped static PIE size is 19,224,296 B. Build usedscripts/auth-toolchainand pinned Zig 0.15.2 for the native terminal library. Candidate arm size is pending.Cold-action profile runtime result: three interleaved 100-sample real-PTY runs on infraternal-dev (12 logical CPUs, Intel i9-9900K), under systemd CPUWeight=10000; 1/5/15-minute load at the startup/RSS run began at 15.82/30.25/39.96. Baseline and candidate both fail the native same-session flood latency gate in all three echo runs. Median same-session PTY p99 was 46.12 ms before and 47.63 ms after (+1.51 ms), while no-flood and other-session metrics passed for both. Host load made p99 variable (before 34.88–70.12 ms; after 38.85–204.63 ms), so this does not establish a regression; repeating at lower load before final acceptance. Evidence: $HOME/.cache/codex-scratch/size-cut/echo-cold-plugins.log and runtime-cold-plugins.log.
Aarch64 static candidate built with only
infraternal-plugin-releaseandinfraternal-plugin-host-factsat opt-levels: 19,102,424 B vs 19,224,296 B at basee4942e4c(121,872 B saved). x86_64 candidate is 21,538,736 B vs 21,709,776 B (171,040 B saved). Arm section deltas: .text -105,088 B, .rodata 0 B, .data.rel.ro -912 B; x86: .text -149,440 B, .rodata -4,096 B, .data.rel.ro -928 B. Arm SHA-256 dfd7d62440d4f00faff6f4941a9ea3d855c4ab36caa9d510fa08fc417e9b90e0. Evidence artifacts and commands are in $HOME/.cache/codex-scratch/size-cut; both builds use the pinned Zig static toolchain.Static x86_64 musl attribution at base
e4942e4c(stripped PIE, 21,709,776 B), compared with oldest measured #57 artifactac03b191(16,142,672 B; growth +5,567,104 B).Feature deltas are independent and non-additive; product capabilities remain enabled.
[Unknown]includes Ghostty and other native symbols, so it is not attributed wholly to the terminal engine. The full 138-crate table and cargo-bloat top 100 symbol table are indocs/verification/size-175.md.Committed the profile cut as
720c1d2043. x86_64: 21,709,776 -> 21,538,736 B (-171,040); aarch64: 19,224,296 -> 19,102,424 B (-121,872). Touched-crate clippy passed; tests passed: host-facts 13, release 7, release restart integration 1, plus doc tests (2 existing ignores). Interleaved local startup, attach, and PTY results are recorded in docs/verification/size-175.md; same-session flood remained over budget on both artifacts.Rejected removing Axum's unused

As expected, savings exceed their 659.4 KiB attributed size because no-asm removes other assembler paths too. Product worktree is clean.S2 finding:
quinn-proto0.11.19 keeps direct ring calls insidesrc/crypto/rustls.rsfor Retry Integrity tag verification and generation (lines 194-198, 555-560);configured_provider()(lines 582-587) only selects ring or AWS-LC. A rustls-openssl provider feature alone therefore does not compile without ring. The scratch build confirmed unresolvedaeadreferences. The minimum prototype must replace those fixed AES-128-GCM calls and add an OpenSSL default-provider branch in a scratch Quinn patch. No product source changed.S2 follow-up finding: the ring path is not confined to Rustls. In
quinn-proto0.11.19src/config/mod.rs,EndpointConfig::newconstructs its reset-key HMAC with ring (around lines 177-189), andServerConfig::with_cryptoderives handshake-token keys with ring HKDF (around lines 391-406); both APIs are gated onringor AWS-LC features. The scratch rustls-openssl provider build therefore needs Quinn'sringfeature for the existing QUIC token/reset implementation. The minimum viable provider prototype changes TLS crypto but retains ring, so it cannot meet “one crypto library” without a wider Quinn fork. I am measuring that retained-ring variant's binary delta and QUIC timings.S2 size step complete (scratch only): the rustls-openssl 0.4.2 provider prototype built as a static x86_64 musl app at 21,151,056 B versus the base 21,542,832 B (−391,776 B, −1.82%).

No product source changed.The first HTTPS smoke exposed a loopback harness artifact: its 1 MiB body took 8.53 s (0.117 MiB/s, 8.83 ms process CPU). The accepted socket already used NoDelayAcceptor; the client socket did not set TCP_NODELAY. I am correcting the scratch harness and will discard this timing before the paired sweep.
After setting TCP_NODELAY on both loopback endpoints, the 1 MiB smoke is now 4.86 ms / 205.6 MiB/s (base) and 9.03 ms / 110.7 MiB/s (no-asm), a 46.2% no-asm throughput loss on the AVX2-only perf VM. Load average was 0.09. These are fixture checks, not the five-run results; they confirm the earlier 8.53 s sample was invalid and will be discarded.
I re-ran
cargo tree --offline --locked -i ringon the branch: ring 0.17.14 is pulled directly by quinn-proto 0.11.19 and rustls 0.23.45 (rustls-webpki also depends on it); quinn 0.11.12 reaches agent, server, and remote-plugin builds. In the provider scratch tree, rustls and rustls-webpki no longer pull ring, but quinn-proto still does. This confirms the measured provider switch cannot remove ring from the shipped graph without replacing Quinn's own HMAC/HKDF use.Functional QUIC smoke found that filtering the provider to AES-256 or ChaCha alone removes the AES-128 suite Quinn needs for QUIC Initial packets (
NoInitialCipherSuite). I retained AES-128 as the Initial fallback and ordered the requested TLS suite first in the scratch harness. The non-timing smoke now passes for AES-128-GCM, AES-256-GCM, and ChaCha20-Poly1305; measured artifacts are being refreshed before those cases run.S1 sweep complete: 150 interleaved process runs (5 repeats per variant/path/cipher/workload), raw output at
/root/infraternal-bench/size-crypto/s1-runs.raw. Perf VM is i9-9900K, AVX2 present and AVX-512 absent; the build host also lacks AVX-512. HTTPS echo p50/p99 medians across repeats were base/no-asm: AES-128 56/181 vs 55/180 us; AES-256 54/183 vs 57/195 us; ChaCha 55/184 vs 56/185 us, with overlapping repeat ranges. On this AVX2-only VM, HTTPS AES-GCM throughput fell 75.5% (AES-128: 495.1 to 121.3 MiB/s) and 83.6% (AES-256: 633.2 to 104.0 MiB/s); QUIC AES-GCM losses were 0.8% and 0.4%. Since no AVX-512 machine was available, D257's required AVX-512 throughput criterion cannot be shown; the no-asm option is a FAIL pending evidence, despite echo staying within observed noise. OpenSSLno-asmdisables more than AVX-512 and the pinned source has no selective no-AVX-512 Configure option.S2 AES-128-GCM QUIC handshake path completed five interleaved process runs, 200 fresh mutual-TLS handshakes each, on the perf VM. Base p50 median/range was 803 us (779–820); per-process p99 median/range was 1,838 us (1,314–3,152). The full OpenSSL no-ring candidate was 2,154 us (2,091–2,354) p50 and 7,067 us (4,040–10,303) p99: 2.68x and 3.85x the base medians. This cipher path is slower and cannot satisfy D257's no-slower condition. The remaining ciphers and passkey repetitions are still running; the full option decision follows those results.

The exact output is in the scratch gate log until the milestone result is recorded.S2 AES-256-GCM QUIC handshake path completed five interleaved process runs, 200 fresh mutual-TLS handshakes each, on the perf VM. Base p50 median/range was 814 us (811–868); per-process p99 median/range was 1,462 us (1,258–3,035). The full OpenSSL no-ring candidate was 2,305 us (2,228–2,685) p50 and 5,982 us (3,674–7,688) p99: 2.83x and 4.09x the base medians. This cipher also fails D257's no-slower condition.

No product source or dependency files changed; timed S2 results are still running.S2 sweep complete on the perf VM: five interleaved process runs per variant/cipher, 200 fresh mTLS QUIC handshakes per process. Full no-ring app is 21,088,336 B vs 21,542,832 B base (−454,496 B, −2.11%). Process-level handshake p50 medians (base → no-ring) were AES-128 803 → 2,154 µs (2.68×), AES-256 814 → 2,305 µs (2.83×), and ChaCha 783 → 2,073 µs (2.65×); p99 medians were 1,838 → 7,067 µs, 1,462 → 5,982 µs, and 1,256 → 4,580 µs respectively. Passkey fixture ran five interleaved processes × 500 actual finish_passkey_authentication calls: p50 86 → 86 µs, p99 181 → 182 µs (candidate range 163–496 µs). The same passkey binary/verifier is used for both labels because WebAuthn already uses OpenSSL and is unchanged by ring removal. Raw run/load/unit/invocation data is in docs/verification/size-crypto-options-runs.csv; the full scratch candidate tree has no normal ring dependency. S2 fails D257: QUIC is 2.65–2.83× slower at p50 and passkey p99 is 1 µs higher. No product files changed.
S1 actual terminal echo probe completed on the perf VM, five interleaved base/no-asm processes with 100 keystrokes each at RTT=0. Real PTY echo p50 median/range was 0.19 ms [0.17–0.22] base and 0.19 ms [0.14–0.21] no-asm; p99 was 0.67 ms [0.33–1.04] and 0.61 ms [0.36–0.82]. Ranges overlap, so the echo result is unchanged within run-to-run variation. All ten runs passed the 34 ms fixture budget and exited 0. The measurement uses the real PTY fixture and excludes the fixture's flood workload. Raw output is in docs/verification/size-crypto-options-runs.csv. S1 remains FAIL under D257 because no AVX-512 machine was available and the broader no-asm build lost 75.5%/83.6% HTTPS AES-GCM throughput on the available AVX2 CPU.

Across five 200-handshake processes per cipher, QUIC p50 was 2.65–2.83× higher and p99 3.65–4.09× higher. Passkey p50 tied at 86 µs; p99 rose 181→182 µs. The MIT provider has three releases from 2026-08-14 through 2026-10-02, a concentrated maintainer base, no open issue marked security-related, and no published advisory listed.

234195bfcf0fde25c488453d772d31b33097beb2. The x86 static release gate now inspects the linkedlibcrypto.aobject, bounds its text to 16 bytes, and checks all 8 fallback symbols. The candidate check passes with 8 text bytes; the baseline control fails at 696,040 bytes.bash -n scripts/verify.d/rust.shandgit diff --checkpass. The checked candidate uses OpenSSL 3.6.3 from the pinned source dependency.The clean
origin/devcontrol build atb182529fcc38ed65c53ad323b55e444beaa4e2a7is stripped and static, but measures 22,275,888 bytes, 71,584 bytes above the existing 22,204,304-byte x86_64 ceiling. I will set the new ceiling from the measured candidate binary, not derive it from the old ceiling. Evidence: baseline build log, binary size and SHA.Perf VM comparison completed on the 4-vCPU i9-9900K (no AVX-512 flags), pinned to CPU 1. Load average moved from 0.34 to 1.31 during the run. Five samples used 8 GiB per AES-GCM sample and 1,000 handshakes per TLS/QUIC sample. Paired candidate/baseline median deltas: AES-128-GCM +12.4% (3,579 vs 4,253 MiB/s medians), AES-256-GCM -6.2% (3,447 vs 3,188 MiB/s); TLS p50 -12.5% and p99 -9.8%; QUIC p50 -3.2% and p99 -5.8%. Raw ranges overlap broadly, so these short local results show no consistent regression but do not resolve small changes. On this CPU, AES-GCM dispatch cannot select AVX-512 code.
Evidence: raw pinned measurements, summary. The exact shipping binary size is still pending.
Step 3 committed and pushed:
e35112f6c78a3406b1d4101299ffc107384d3331. The archive gate now resolves the repositorytarget/whenCARGO_TARGET_DIRis unset. The no-env check reaches the intended missing-archive message instead of raisingKeyError; with the candidate archive configured, the gate passes at 8 text bytes with all 8 fallback symbols.git diff --checkpasses.The full branch product build has generated its candidate archive, and the release gate passes: the AES-GCM AVX-512 object has 8 text bytes and all 8 fallback symbols. Product
libcrypto.ais 39,876,556 bytes versus 40,891,356 baseline (-1,014,800 bytes). The standalone candidate harness archive differs from the product archive by 28,600 bytes, so I am relinking the candidate harness to the exact product archive and will replace the earlier perf comparison before reporting performance. Evidence: product archive gate, product/harness archive hashes.Exact-product perf VM sample completed on the i9-9900K (4 vCPU, AVX-512 absent), pinned to CPU 1; load average rose 0.92 to 1.43. Each variant used five 8-GiB AES-GCM samples and five batches of 1,000 TLS/QUIC handshakes, linked to the product archives.
Candidate vs baseline medians: AES-128 2,207.58 vs 2,393.97 MiB/s (-7.8%); AES-256 2,074.82 vs 2,035.23 MiB/s (+1.9%). TLS p50/p99 2,676/5,573 vs 2,702/5,345 us; QUIC p50/p99 1,446/3,428 vs 1,511/2,663 us. Sample ranges overlap and vary materially between runs, so this series does not resolve small differences or establish a p99 regression. I will collect an additional exact-product series before closing the performance measurement.
Raw results: perf-results-final.txt
Summary: perf-summary-final.txt
Completed the exact-product perf comparison: ten samples per variant, on the i9-9900K (4 vCPU, no AVX-512), pinned to CPU 1. Candidate and baseline harnesses link the respective product OpenSSL archives. Candidate archive SHA-256 is 4bb6923dbc9cbe1c6bf743854de9c9fcb9a6531e10a708d300d7119728574d42.
Candidate vs baseline pooled medians: AES-128 2,409 vs 2,548 MiB/s (-5.4%); AES-256 2,166 vs 2,146 MiB/s (+1.0%). TLS p50/p99 2,556/5,693 vs 2,630/5,573 us (-2.8%/+2.2%). QUIC p50/p99 1,416/3,095 vs 1,523/3,242 us (-7.0%/-4.5%). Per-variant ranges overlap materially; there is no consistent handshake regression. AES-128 is 5.4% lower at the pooled median, within broad observed run-to-run spread. This supports no material measured change at this precision, not a formal equivalence bound.

scripts/verify iteratestopped at the latency-proxy self-test after its other completed rows passed. It reported configured RTT 300 ms, p50 312.49 ms, p99 369.20 ms; the self-test allows p99 through 360 ms and p50 through 345 ms for the default 30 ms jitter. No latency-proxy code was changed in this lane. I am checking whether this is a transient scheduling outlier by reproducing the check before continuing.Gate output: verify-iterate-final.log
Correction to my previous gate note:
scripts/verify iterateuseslatency_proxy.py self-test --samples 3at scripts/verify:106 (the 31-sample check belongs to a separate release verification path). The first three-sample result failed the 360 ms p99 ceiling at 369.20 ms (p50 312.49 ms). A rerun passed at p50 301.98 ms / p99 357.56 ms, with no code changes. This is consistent with one timing outlier; the iteration gate is continuing through its Rust rows.Correction: the latency self-test outputs noted above came from
scripts/verify iterateon the shared build host. The environment rules require timing and latency evidence to come from the perf VM, so those outputs are gate diagnostics only and are not performance evidence. My earlier suggestion that the discrepancy indicated a scheduler outlier was unsupported. The rerun proceeded past that self-test with no source changes; I will use only perf VM measurements for performance conclusions.scripts/verify iteratefailed one Rust test:real_shell_reconnect_resize_and_delivered_exitincrates/infraternal/tests/shim.rs. The failure wasWouldBlockfromread_exactin the shared frame-read helper (shim.rs:270);Session::connectinstalls a read timeout. The same test binary had 23 other tests pass. No shim test or runtime code changed in this lane. The exact failure excerpt is attached; I am rerunning this single test before deciding whether the failure reproduces.Evidence: iterate-shim-failure.txt
The shell reconnect test passed when isolated, and rerunning the complete shim test binary passed all 24 tests. The earlier
WouldBlockhas not reproduced; no source changes were made. I am rerunning the full iteration gate to confirm the workspace passes end to end.Rerun receipt: shim-suite-rerun.log
Ran the latency-proxy self-test on the perf VM under the shared measurement lock. On x86_64 / 4 vCPU (load 0.23, 0.92, 1.12), its configured 300 ms RTT check passed: p50 307.41 ms, p99 313.11 ms. This is test-fixture timing evidence only; the build-host outputs above remain gate diagnostics and are not used as performance measurements.
Receipt: perf-vm-latency-check.log
The scoped iteration retry passed latency, fmt, compile-out, clippy and the main unit tests, then
agent_queuesfailed on its first terminal open withresource_unavailable. No code in this lane changes that test or terminal admission. Running the existingagent_queuestest binary alone passed. I will run the full iteration gate again to confirm this does not recur in the full suite.Failure excerpt: agent-queues-failure.txt
Isolated rerun: agent-queues-rerun.log
The scoped iteration run failed one
infraternal-serverunit test:saturated_native_control_queue_does_not_hide_primary_terminal_output. It had already established an active full control queue, a live primary, and no shadow output, but the primary terminal output was not observed before the test deadline. 422 server tests passed; 46 were ignored. This is not one of the documented host-load baseline exceptions. I am reproducing this single timing-sensitive test on the perf VM and will rerun it in the normal suite afterward.Failure excerpt: server-control-queue-failure.txt
The exact server control-queue test passed on the perf VM under
/var/lock/perf-bench.lock: 1 passed, 468 filtered, on x86_64 / 4 vCPU, pinned to CPU 1. Perf VM load average was 3.14 / 2.42 / 1.83 at both start and finish. This supports (but does not prove) that the worktree-suite failure was host scheduling contention; no server code changed. I will rerun the worktree gate with test concurrency capped so unrelated tests do not compete for the same local resources.Perf VM receipt: server-control-queue-perf-vm.log
Exact server control-queue test on the perf VM passed 1/1 (468 filtered) on x86_64, 4 vCPU; load average 3.14/2.42/1.83. Receipt: https://git.kayg.org/attachments/fa377db7-bafa-4800-9d6c-93283be064d0. This confirms the isolated timing-sensitive case only; the worktree iteration gate remains outstanding.\n

The stripped static baseline and branch image are both 19,704,712 bytes (65,968 above the existing 19,638,744 cap); the D268 wrapper condition is x86_64-only, so no aarch64 cap was changed.

The same fast run exposed a stale static-size test parser (max Nversus gatecap: N bytes). The parser is corrected in the worktree; synthetic exact-cap/plus-one/shrink tests pass for x86_64 (21,491,152) and aarch64 (19,638,744), plus unsupported-target rejection.

The final fast gate still has two failures. The aarch64 image is 19,704,712 bytes, 65,968 above the existing 19,638,744 cap; a clean origin/dev build produces the same size.
