Browser terminal floods receive 1013 stream closes and automatically reconnect on a healthy local link. Found while measuring #260; this issue is for the product bug, separate from the research harness. No fix is included in the research branches.

Reproduction: research-head-to-head at 78ccce47e744 plus the research-only browser-flood.ts driver; production aarch64 musl server, production tracer build, real embedded infraternal agent, shim and PTY, Chromium 155.0.8059.79 on std02. No packet loss or injected delay. The existing real-server fixture supplies a lean TLS/WebSocket front; it does not record or concatenate output text. A software passkey signs up through the production UI. Each of three runs cats 75,000,000 random bytes encoded as base64 with 120-column wrapping, then prints a marker absent from echoed input.

Run	Final marker visible	Stream closes	Socket recovery
1	yes	control 1001 (connection replies stopped), two stream 1013 (attachment ended)	three replacement sockets
2	yes	two stream 1013 (attachment ended)	two replacement sockets
3	yes	none	no replacement

These are build-host functional reproductions, not perf timing evidence. Completion after automatic recovery does not prove uninterrupted delivery or preservation of every output byte. Runs 1/3 delivered approximately 101.67 MB including PTY newline expansion; run 2 delivered only approximately 49.06 MB before the final marker after recovery.

Confirmed code path for the generic 1013: crates/infraternal-server/src/websocket.rs forwards an attachment receiver until it ends, then synthesizes TerminalOutput::Closed { code: 1013, reason: "attachment ended" }. In embedded.rs, Incoming::Output calls retire_stream on a sequence gap or failed bounded output admission; retire_stream removes the attachment/sender before sending a close to the infraternal agent. This loses the precise local retirement reason at the browser boundary. The output queue is bounded to 256 events, while byte credit is independently bounded. Temporary content-free instrumentation is being used to distinguish queue exhaustion from sequence gaps in this reproduction; the 1001 control close is a distinct liveness path, not a 1013 liveness code.

Minimal proposal, pending diagnostic attribution: preserve the precise retirement reason, add a failing production-browser flood regression, and make output admission/forwarding honor the outstanding byte grant without retiring a healthy viewer on a burst of small frames. Keep per-viewer isolation and resource bounds. Investigate the independent control-reader admission/liveness stall if the diagnostic trace confirms it. Do not merely raise the keepalive timeout or globally remove backpressure.

Local source/evidence: /home/kayg/.cache/codex-scratch/j20/evidence/browser-flood; remote equivalents are under /home/claude/.cache/codex-scratch/j20/evidence/ on std02.

J20 diagnostic follow-up: the 1013 trigger is confirmed as bounded output queue admission failure, not a sequence gap or a keepalive timeout.

An instrumented rebuild of the same production baseline on std02, with Chromium 155.0.8059.79 and the same three ~100 MB terminal floods, emitted J20_OUTPUT_ADMISSION_FAILED capacity=0 closed=false four times. There were four corresponding stream-1 1013 closes across the runs (1 / 2 / 1). There were no J20_OUTPUT_SEQUENCE_GAP markers. Each run reached its final screen marker, but delivered only 88,062,697 / 33,018,364 / 69,027,559 protocol output bytes, so completion does not prove full output delivery after snapshot recovery. Build-host durations are functional reproduction evidence only.

Code path at research-head-to-head baseline 78ccce47e7:

• embedded.rs, Incoming::Output: attachment.output.try_send(...) fails while the receiver is open because the 256-message queue is full. Byte credit and message capacity are separate bounds.
• retire_stream removes the attachment and its output sender, then sends a close toward the infraternal agent.
• websocket.rs's output forwarder drains/ends and synthesizes stream close 1013, reason attachment ended, losing the local retirement reason.

One diagnostic run also had a separate control-stream 1001 (the server stopped receiving connection replies). The application-admission diagnostic emitted no >100 ms stalls, so this trace does not establish the cause of that separate liveness expiry. The original roughly 500 ms keepalive observation does not explain the confirmed stream-1013 path.

Minimal follow-up proposal only: preserve the precise retirement reason at the browser boundary; add a production-browser flood regression that checks continuity, closes and recovery; investigate aligning queue admission with granted byte credit so a healthy reader is not retired merely because many small output frames exhaust the message bound. Retain explicit memory bounds and per-attachment isolation. Increasing keepalive timeouts would not address this confirmed 1013 trigger. No product fix is included in J20.

Temporary diagnostics were confined to the remote scratch checkout and have been restored. Attached diagnostic log/JSON/screenshots preserve the observation; no diagnostic source change will be pushed.

J20 browser-triage handoff: reproducible production-Chromium harness committed as c42c3f103 on research-head-to-head, final branch head ad8eb0c318, pushed. The confirmed queue-admission finding and minimal proposal remain above; no product fix or diagnostic instrumentation is included. The separate control-stream 1001 cause remains unconfirmed.

The unchanged full scripts/verify fast shared workspace gate passed on compute01 with both research slices and exact final-source hash proof. Final evidence and verbatim summary: #260 (comment).

J20 common final gate exit=0

Browser/diagnostic processes are stopped; original std02 source/binary was restored and J20 build caches are removed. This issue remains open for the product fix.

Finding: J20 instrumented production runs confirmed try_send admission failure with capacity=0 closed=false and no sequence-gap markers. On this base, embedded.rs caps each output queue at 256 events; a full queue immediately calls retire_stream, removes that attachment, and sends 1013. Valid byte credit and event slots are independent, and the WebSocket forwarder can pause behind its separate four-event connection queue. This makes a busy downstream look stalled. The ~500 ms liveness lease does not trigger this 1013; the separate control 1001 remains unproven. The fix will preserve D13 raw bytes and the existing 8 MiB credit bound, with bounded contiguous-frame coalescing so queue pressure applies backpressure instead of retiring the viewer.

J38b start: continuing on branch fix-flood-1013-270, based on origin/dev at 105b1a28d3b3ea86487c457249ab3f953a4c27d3. I am reviewing J38’s two uncommitted regressions, reading the referenced decisions and J20 evidence, then will run failing-first Rust and production Chromium checks on the assigned build VM. I will preserve D13 raw-byte semantics and the existing credit/memory limits unless the documented decision requires an owner question. Next: identify a bounded admission strategy, measure it on the perf VM, run scripts/verify fast, and post the evidence and head.

J38b progress: committed and pushed WIP 2e8465224 on fix-flood-1013-270. I kept J38’s real-server Chromium spec and the retirement-reason regression, and expanded the Rust credit-window case from exactly 256 events to the full 8 MiB window as 4 KiB frames. The Rust test now requires the route and all raw bytes to survive; the browser test checks no stream 1013 and no discontinuous output offsets. These are regression tests only. Next: run them against this unmodified dev behavior on compute01 through build-slot, then implement a byte-bounded coalescing queue if the expected failures reproduce.

J38b progress: reviewed the pushed regression and traced both queue stages: the per-attachment output channel holds 256 events and the WebSocket forwarder channel holds 4; credit is 1 MiB initially and capped at 8 MiB. No production edits yet. From the code host, SSH to claude@infraternal-dev-01-compute01 currently fails DNS resolution, so the queued baseline logs on that VM are not verifiable from here. Retrying the required host path before implementation. Branch fix-flood-1013-270 is at 2e84652246.

Build-host progress: stopped the stale J38 duplicate baseline waiting in build-slot for 37 minutes (PIDs 220476/220486; detached base worktree with only the same two regression files). It was running the same test and had no result, so it would duplicate and delay J38b. The J38b Rust and Chromium baseline jobs remain queued; their logs still show four busy slots and no exit files.

Baseline artifact provenance: compute01 built the test-only J38b head into a 21,431,472-byte static binary, SHA-256 b527c33d9df30659c816b31546c9583b05c85bae87fa7b95eec4e207d589ea3c. The J20 kit manifest lists the same hash for bin/infraternal, so the kit binary is byte-identical to the current no-production-change baseline. I will use it for the pre-fix term-local perf-run measurement.

Browser baseline environment blocker: the production build completed, but Playwright could not launch headless Chromium, so the product regression did not run. The shell reports 13 missing shared libraries, including libnspr4.so, libnss3.so, libatk-1.0.so.0, libgbm.so.1 and libasound.so.2; exit 1 is a launch failure, not the expected product failure. I am rerunning through build-slot with those runtime libraries supplied by a transient Nix shell; no product source change.

It is pinned to /home/claude/worktrees/j38b, which still contains the test-only WIP. The Rust credit-window regression already fails on unmodified production code, and the perf baseline reproduces 1013 with echo p99 1.15 ms; both findings are recorded above. No production source has changed. I am keeping the required browser RED queued and will implement once it reaches its assertion, then rerun it green.

Finding (Chromium baseline environment, compute01): the production build reached its browser launcher after acquiring build-slot (slot 4/4), then exited 1 before Playwright because ldd still found ten missing runtime libraries: glib/gobject/gio, dbus, X11/Xext, GBM, expat, xcb and udev. This is not a product assertion result. I am adding those libraries to the transient Nix shell and rerunning against the same test-only worktree.

Finding (Rust baseline, compute01): retirement_reason_reaches_the_browser_even_when_the_notice_queue_is_full exited 101 on the test-only branch with unchanged production code. With the one-slot queue holding an Ack, retire_stream removed the sender; the receiver got no typed Closed { who: Server, code: 1013, reason: "reader fell behind; reattach" }. This confirms retirement reason delivery is not reserved when the normal event queue is full. The corrected production-Chromium baseline remains queued at position 10 after its dynamic-library check passed; no production source changed.

J38b update: the production Chromium baseline failed before reaching the product assertion on compute01. The nixpkgs-unstable transient browser libraries require GLIBC 2.43, while the VM has GLIBC 2.41. This is an environment blocker, not a product result. I’m locating a Nix-provided runtime compatible with 2.41, then I’ll rerun the test-only RED baseline. WIP regression tests remain pushed at 2e84652246.

The spec still stopped before any flood because the configured INFRATERNAL_TEST_STATE_ROOT under /home/claude/.cache/codex-scratch/j38b/runtime makes the fixture's AF_UNIX session socket exceed its 107-byte limit (server.ts:128-130).

J38b continuation: required project docs, #270, and the cited #260 J20 comments are read. Branch fix-flood-1013-270 remains at test-only WIP 2e846522466b898c3e8c5d207b32d0cdc9cd4b87 (base 105b1a28d3b3ea86487c457249ab3f953a4c27d3).

I found the byte-bounded coalescing implementation and regression edits left uncommitted; I am preserving them as a WIP commit and pushing before continuing. Next: rebase, verify the red/green queue and Chromium cases, measure bounded memory and flood behavior, run the fast gate, then report findings.

J38c progress: pushed WIP 001eb32be with an ignored memory probe for 50 stalled attachments at the full 8 MiB credit window each. That workload retains 400 MiB of payload by design; the probe also asserts each queue's byte/event bounds and will report measured RSS delta per attachment on the perf VM. The prior 128 × 1 MiB probe assumed one event per 4 KiB frame, which is no longer valid after coalescing. RED follow-ups remain queued in compute01 build-slot; source and logs are preserved under the J38c scratch path.

Finding (source review): the custom output sender is intentionally nonblocking, so the strengthened stalled-reader test could not use the old mpsc send().await API. I changed it to try_send, which is the production admission path, and pushed WIP 2ba5dc0e6. A final compile will verify the queue abstraction and all tests together.

J38c finding (dev-base RED and perf baseline):

• On compute01, unchanged production code at f4b61cd6c3f52078cad7573c5367d7a6e75f84f0 plus test-only commit 23a0eec5b fails retirement_reason_reaches_the_browser_even_when_the_notice_queue_is_full (0 passed, 1 failed). The assertion confirms the typed server 1013 close is absent after the normal queue fills. The full-credit stalled-viewer regression was also confirmed RED on this dev base earlier in this run.
• Built the dev-base static PIE on compute01: 21,443,824 bytes, SHA-256 b2cec7a205c522dff4f0f68c07bb2e1da93a9f81f234111ef29420bb2a5d4ed1.
• Ran J20's term-local kit on infraternal-perf-01-backup01 through perf-run --root. Infraternal echo p50/p99 was 0.82/1.79 ms; the 100 MB flood, subsequent yes, and reattach failed with h2h: stream closed 1013: attachment ended. The case took 78 s and its machine diff was empty. Results: /home/claude/.cache/codex-scratch/j38c/perf/h2h-kit-compare/results/20261101T070230Z.

The production Chromium RED is still running on compute01 through build-slot. Its log and fixture state are /home/claude/.cache/codex-scratch/j38c/browser-red.log and /tmp/j38c; it now uses the final spec with a healthy 4 MiB/s browser link. The corrected Rust queue regressions are also queued there.

The full-credit stalled-viewer regression was also confirmed RED on this dev base earlier in this run. - Built the dev-base static PIE on compute01: 21,443,824 bytes, SHA-256 `b2cec7a205c522dff4f0f68c07bb2e1da93a9f81f234111ef29420bb2a5d4ed1`. - Ran J20's `term-local` kit on `infraternal-perf-01-backup01` through `perf-run --root`. Infraternal echo p50/p99 was 0.82/1.79 ms; the 100 MB flood, subsequent `yes`, and reattach failed with `h2h: stream closed 1013: attachment ended`. The case took 78 s and its machine diff was empty. Results: `/home/claude/.cache/codex-scratch/j38c/perf/h2h-kit-compare/results/20261101T070230Z`. The production Chromium RED is still running on compute01 through build-slot. Its log and fixture state are `/home/claude/.cache/codex-scratch/j38c/browser-red.log` and `/tmp/j38c`; it now uses the final spec with a healthy 4 MiB/s browser link. The corrected Rust queue regressions are also queued there.

J38c browser RED on the unchanged dev implementation (f4b61cd6c3f52078cad7573c5367d7a6e75f84f0 plus test-only source): the production tracer, production static server and real embedded infraternal agent reached the flood assertions. With the healthy browser link capped at 4 MiB/s, run 1 reached its marker after 98.39 s and received 86,264,163 output bytes. Run 2 reached its marker after an automatic socket replacement in 2.708 s, after only 2,047,849 bytes; it recorded a control-stream 1001 (the server stopped receiving connection replies) and a raw-output offset regression on stream 1 (expected 102240310, received 102207542). The spec failed on the sequence-gap assertion; it did not observe a stream 1013 in these two runs, so this run does not independently confirm the 1013 close code. That distinction is separate from the Rust RED proving the full event queue drops the typed retirement close.

J38c progress, branch remains safely pushed at 2ba5dc0e6088de2df85167f8e6d82cdd257391e2 with no uncommitted implementation changes. The dev-base production Chromium spec reached the product assertions and failed on a raw-output offset gap after a control-stream 1001; it did not observe a stream 1013 in that run, as recorded above. The dev-base perf case is complete and reproduced attachment ended 1013.

I refreshed the detached dev test worktree with the final Rust regressions (test files only; production source remains at f4b61cd6c3f52078cad7573c5367d7a6e75f84f0) and queued all five queue/order cases together through build-slot. Last observed queue position was 5. Log: /home/claude/.cache/codex-scratch/j38c/rust-red-current.log. Next: record those RED results, run the exact queue/browser regressions green on the pushed branch, measure 50-viewer RSS and final perf, then run scripts/verify fast.

J38c Rust baseline test update: the first attempt at refreshing all final regressions into the detached dev-base worktree exposed test-only references to the new OutputQueueSender and terminal_output_channel; that copy could not compile against the old implementation. I adapted the detached test copy to the existing mpsc::Sender/mpsc::channel API and restarted the queue suite. No dev production files changed. Current launcher/log: /home/claude/.cache/codex-scratch/j38c/rust-red-current-rerun.pid and rust-red-current-rerun.log; it is queued through build-slot (last observed position 9).

J38c compile finding (build-slot on infraternal-dev-01-compute01, WIP head 2ba5dc0e60): the green focused Rust run failed before executing tests with 19 compile errors. The output-channel replacement left callers on the old Tokio receiver API: websocket.rs could not call the private OutputQueueReceiver::recv; the auth credit helper returned mpsc::Receiver; and regression/path/liveness fixtures supplied mpsc senders or receiver function pointers. Evidence: /home/claude/.cache/codex-scratch/j38c/rust-green.log. I have updated those fixtures and made the queue receiver usable by the crate WebSocket consumer; rerunning the focused cases now.

Finding (production build on compute01 through build-slot, WIP head 563a9882f637e4e982714d0f85a86b13aea58d9f): the Chromium stage stopped before Playwright because the production feature set exposed two missing sender methods in embedded_priming.rs:684:

error[E0599]: no method named `capacity` found for struct `OutputQueueSender`
error[E0599]: no method named `is_closed` found for struct `OutputQueueSender`

The focused Rust queue suite had not compiled this production caller. The shadow-priming path uses these checks to avoid delivering an unsafe candidate frame into a full or closed primary queue. I added sender state probes backed by the bounded queue mutex and a regression for available event slots and receiver closure. Original build log: /home/claude/.cache/codex-scratch/j38c/browser-green.log; the patched test is queued for compute01 build-slot.

J38c history cleanup: the pushed WIP stack is now one reviewable change, b41b6dc47a9c55e1348ac86ef86e5add258b0052, on fix-flood-1013-270, based on the requested f4b61cd6c3f52078cad7573c5367d7a6e75f84f0. The tree is unchanged by the squash. The focused sender API test remains queued on compute01 (log /home/claude/.cache/codex-scratch/j38c/queue-api-green.log); the production static build and Chromium flood rerun are queued behind it (log /home/claude/.cache/codex-scratch/j38c/browser-after.log). The J20 kit checksum passed and its extracted copy is staged under /home/claude/.cache/codex-scratch/j38c/perf/after-kit-b1ed9d8 for the after measurements. Earlier evidence on this same source tree: five queue regressions pass; 50 full-credit queues add 413,448 KiB RSS, 8,268.96 KiB per attachment. Next: complete production browser and perf runs, run scripts/verify fast on the final head, and remove the J38c target.

J38c history cleanup: the pushed WIP stack is now one reviewable change, `b41b6dc47a9c55e1348ac86ef86e5add258b0052`, on `fix-flood-1013-270`, based on the requested `f4b61cd6c3f52078cad7573c5367d7a6e75f84f0`. The tree is unchanged by the squash. The focused sender API test remains queued on compute01 (log `/home/claude/.cache/codex-scratch/j38c/queue-api-green.log`); the production static build and Chromium flood rerun are queued behind it (log `/home/claude/.cache/codex-scratch/j38c/browser-after.log`). The J20 kit checksum passed and its extracted copy is staged under `/home/claude/.cache/codex-scratch/j38c/perf/after-kit-b1ed9d8` for the after measurements.

J38c queue update: the branch is pushed at b41b6dc47a9c55e1348ac86ef86e5add258b0052, directly on the requested origin/dev base f4b61cd6c3f52078cad7573c5367d7a6e75f84f0.

The focused sender API regression has waited about 46 minutes in compute01 build-slot (log /home/claude/.cache/codex-scratch/j38c/queue-api-green.log, last queue position 14). The production static build/Chromium rerun has waited about 25 minutes (log /home/claude/.cache/codex-scratch/j38c/browser-after.log, last queue position 18). scripts/verify fast is queued behind them (log /home/claude/.cache/codex-scratch/j38c/verify-fast.log, last position 19). Compute01 is reachable with 55 GiB free, but all four shared build slots are still occupied; I am keeping these jobs in the required queue.

On infraternal-perf-01-backup01, a fresh baseline term-local run through the kit's perf-run wrapper again reproduced 1013: attachment ended during the 100 MB flood, follow-up output, and reattach. Echo was p50/p99 0.91/7.79 ms; the case machine diff is empty. The same baseline invocation is waiting for the perf lock before its WAN/loss cases. Log: /home/claude/.cache/codex-scratch/j38c/perf/term-before-all.log.

Next: finish the baseline WAN/loss cases, then the queued sender/browser/gate runs, repeat performance with the fixed binary, attach production screenshots, report both static sizes versus dev, and clean the target directory.

J38c blocker update: compute01 now has 19 GiB free, below build-slot's 25 GiB admission threshold; all four build slots remain occupied. The sender regression, production build/Chromium rerun, and scripts/verify fast remain queued (logs: /home/claude/.cache/codex-scratch/j38c/queue-api-green.log, browser-after.log, verify-fast.log). No J38c target has been created. I am preserving the queue and will resume these stages when slot and disk capacity clear.

The independent perf baseline is on term-loss after completing the local and WAN cases. Its log is /home/claude/.cache/codex-scratch/j38c/perf/term-before-all.log.

J38c perf baseline (origin/dev binary) is complete on infraternal-perf-01-backup01 through the J20 harness. The archive /home/claude/j20/final-kits/h2h-kit-x86_64-78ccce47e744-j20-final.tar.gz passed its sidecar SHA-256 check; the extracted harness manifest matches the run copy. Each case used the kit's installed perf-run --root; all three machine diffs are empty. Full summary: /home/claude/.cache/codex-scratch/j38c/perf/h2h-kit-compare/results/20261101T115807Z/summary.md.

• term-local (79 s): infraternal echo p50/p99 0.91/7.79 ms; the 100 MB flood, follow-up output, and reattach failed with 1013: attachment ended.
• term-wan (429 s, 150 ms one-way): echo p50/p99 300.94/303.26 ms; 100 MB flood failed with 1013; reattach p50/p99 1203.27/1207.63 ms.
• term-loss (692 s, 150 ms one-way + 2% loss): echo p50/p99 300.95/710.09 ms; the infraternal marker arrived in 5.48 s with 5,616,640 bytes delivered; reattach p50/p99 1204.82/1585.68 ms. Zellij over SSH timed out in its flood and reattach rows.

The machine load at the local case start was 2.66, and the recorded steal was 669/31,484 jiffies; WAN and loss also record their load/steal in their receipts. These are shared-host comparison measurements, not a clean isolated microbenchmark. Next: replace only the infraternal binary in the checksum-verified extracted kit copy and repeat all three cases after the fix.

J38c test-filter correction: the focused sender command was admitted on compute01 at 13:22:35 and compiled, but its --exact filter selected zero tests (0 passed, 0 failed, 457 filtered out). The test is nested under embedded::regressions; I am not counting that run as coverage. The queued scripts/verify fast workspace test will execute it along with the five queue/order regressions on the final branch head.

J38d finding: the previous J38c run state is not reusable as a completed verification. queue-api-green.log selected zero tests (0 passed, 457 filtered out); browser-after.log has no exit file and its recorded PID is no longer running. verify-fast.exit is 1; its log shows the legacy x86 static-size row at 21,448,080 bytes against 21,443,824 (+4,256 bytes), then ends during another compile. This matches the brief's known old-cap gate behavior, but is not a clean final gate. Current J38d head after rebase is 3383c2f841848f45fd46c854141c6a4430bdc544 on current origin/dev a26615c50e76ed86f36d25aa094283cf840d5320. I will rerun the focused tests, browser regression and final gate from the J38d worktree.

J38d progress: rebased the resumed fix onto current origin/dev and pushed branch fix-flood-1013-270-j38d. Commit 560d7f133 strengthens the production-browser flood regression: it requires the received protocol output to cover the generated fixture bytes and forbids snapshot recovery or browser socket replacement during each flood, so a restored final marker cannot hide missing raw PTY output. Next: run the carried Rust regressions and the production Chromium case on a VM via build-slot, then collect before/after flood latency evidence and the final compute01 gate.

J38d build-host update: dev-02 currently has 17 GiB free, below build-slot's 25 GiB admission floor. The Rust server test remains queued as PID 3549581; no compile has started, and no build is running outside build-slot. I will keep working from the isolated J38d worktree and resume VM checks when enough disk becomes available.

J38d verification-runner findings, with the carried queue fix unchanged:

• The dev-02 standalone cargo test --locked --jobs 3 -p infraternal-server --lib invocation exited 101 after 427 passed and 8 unrelated failures. All five embedded::regressions cases passed. The failures were fixture/feature setup: five tests require CARGO_TARGET_DIR, and two Mesh refusal cases rely on workspace feature unification. This command omitted the environment that scripts/verify provides, so I am not counting it as a gate; the final scripts/verify fast will use the canonical workspace setup.
• The first exact-dev static baseline attempt exited before compiling infraternal because the runner had not staged the checksum-pinned Zig toolchain (target/auth-tools/zig/zig missing). It is relaunched with scripts/auth-toolchain and output under the J38d scratch target.
• The first browser-after launcher failed before building because nix develop started from /home/claude, outside the repo flake. The detached launcher now changes to the J38d worktree before calling build-slot.

No product source changes were made for these runner corrections. Current baseline and browser reruns remain detached and will be polled.

J38d browser runner update: the corrected dev-02 launch reached the transient Nix browser runtime setup and then exited 127 because the final helper path omitted the j38d- prefix.

J38d code-path finding: the remaining Snapshot/byte undercount is consistent with the agent relay starvation recovery, not the server queue limit. crates/infraternal-agent/src/relay.rs starts a 250 ms deadline when output credit is exhausted or too small for the pending frame. In daemon.rs, expiry clears that pending frame and drops the shim data link; after browser credit returns, the relay reconnects with ReadFrom(output.cursor()). The shim retains 8 MiB and resumes PTY reads with no active cursor, so a fast flood can wrap the ring before ReadFrom, forcing a repaint Snapshot. This path conflicts with lossless raw output for a live, credit-limited viewer. I am making the production-browser regression deterministically pause its main thread past the deadline before changing production code; then I will keep the stream attached under backpressure and preserve control liveness, followed by a green browser run and perf measurement. The original J38d estimate remains ~4 hours active, with slot waits separate.

J38d RED finding (dev-02, test-only head ac3722be2b): the production server/tracer and real PTY delivered the final marker in 1.613 s, but only 572,445 of 100,833,334 fixture bytes arrived.

J38d test finding (dev-02, rust-focused.log): the focused workspace run exited 101 after agent_review reported 6 passed / 2 failed in 92.86 s. Both failures encoded the old 250 ms detach: reaped_shim_exit_survives_a_live_credit_pause waited for an exit notice before credit could drain its final output, and repeated_tiny_credit_pauses_preserve_shell_progress waited for starvation to detach the shim link. The new relay intentionally keeps a live raw-output cursor pinned under backpressure. I am adapting these probes to require ordered raw output and to use explicit disconnect when testing Snapshot resume; the focused rerun will determine whether the implementation is sound.

J38d checkpoint: commit cd9d061a3515fdf14d2ecbbf7a1e4531ce75912b is pushed on fix-flood-1013-270-j38d, rebased onto current origin/dev 65d986191. The agent relay now retains one pending shim frame while live viewer credit is exhausted, so the shim cursor applies PTY backpressure instead of detaching and allowing the ring to wrap; Pongs remain independent of that output pause. I updated the real-shim probes for explicit disconnect versus a live credit pause. Next: rerun Rust regressions and production Chromium on dev-02, then perf-run measurements and the final compute01 gate.

Checkpoint correction: I amended the pushed fix to e9c2b24522eb77b274f9ba0af88ab6ebccaaef9b after static review found the rewritten Snapshot probe needed its select import. The dev-02 job is still queued; its worktree now points at this exact head.

J38d root-cause trace: the agent shim caps one Output frame at 1 MiB, while the server serializes terminal Output frames and proof replies through the same WebSocket writer mutex. At the browser regression's 4 MiB/s throttle, a maximum frame can occupy that writer for about 250 ms, matching the browser liveness floor; the added one-second main-thread pause makes the queueing observable. This explains why the resumed raw-output relay still saw browser-local close 4000 with no Pong response, then Snapshot recovery. I added a focused RED relay regression requiring a credited 1 MiB frame to yield in bounded chunks while retaining an exact contiguous cursor. Next I will run that test against the current code, then cap only the per-write quantum (keeping the 8 MiB credit and frame protocol limits) and rerun the real-browser continuity case.

Correction to the prior liveness hypothesis: the production shim's bulk PTY reads are 16 KiB, so the 1 MiB protocol ceiling is not evidence that this flood held the server writer for 250 ms. I withdraw that specific inference. I stopped the queued relay RED run before it began and removed its uncommitted test; no product code changed. The confirmed evidence remains browser-local 4000 plus the Snapshot byte discontinuity. Next diagnostic: add content-free sent-Ping, received-Pong, and largest-Output-frame counters to the existing failing production-browser regression, rerun through build-slot, and trace whichever direction stops progressing before fixing it.

J38d diagnostic finding (dev-02 production Chromium, current carried fix): run 1 delivered 393,346 / 100,833,334 fixture bytes before the same browser-local 4000 and Snapshot recovery. The wire counters show 5 client Ping frames, 4 matching server Pongs, 4 server Ping frames and 4 browser Pong replies; maximum raw Output frame was 16,384 bytes. This rules out the suspected oversized frame and shows the client closed with one probe unacknowledged, while the opposite proof direction remained active. I am adding probe event timestamps to establish whether that reply was dropped or merely arrived after the deadline before choosing the fix.

J38d queue update: the timestamped production-browser diagnostic is still waiting in dev-02 build-slot (about 12 minutes at the last check); dev-02 has 24 GiB free, below the 25 GiB admission floor, so Playwright has not started. The carried production fix is unchanged. I have staged a deterministic client-liveness regression for active inbound output and the D300 silent-route bound; it has not run yet. I will continue after the queued diagnostic completes.

J38d timestamped production-browser finding (dev-02, head 76533b33bd): run 1 delivered 669,825 / 100,833,334 fixture bytes in 3.732 s, then resumed with a Snapshot at out_seq 101,667,025 after raw output ended at 669,929. The per-socket trace shows the old socket's client Ping (nonce 2) has no matching Pong on socket 1; all four matched client-Ping replies are on replacement socket 2, so this is not a cross-socket match. The proxy logged the production server's upstream close at time 54257, while the browser processed/sent the recorded old-socket Ping/Pong at epoch 1793564255281 (modulo timestamp 55281), about 1.024 s later; the browser then closed socket 1 locally with 4000 at 1793564257880. That ordering points to server-side retirement during the test's deliberate 1 s main-thread pause; it does not prove the missing Pong was merely queued. The focused RED liveness test is still queued on compute01. I am checking this against D300 before changing liveness behavior.

J38d timestamped production-browser finding (dev-02, head 76533b33bd172ab3995f0e1bf6ae52e114e59d3f): run 1 delivered 669,825 / 100,833,334 fixture bytes in 3.732 s, then resumed with a Snapshot at out_seq 101,667,025 after raw output ended at 669,929. The per-socket trace shows the old socket's client Ping (nonce 2) has no matching Pong on socket 1; all four matched client-Ping replies are on replacement socket 2, so this is not a cross-socket match. The proxy logged the production server's upstream close at time 54257, while the browser processed/sent the recorded old-socket Ping/Pong at epoch 1793564255281 (modulo timestamp 55281), about 1.024 s later; the browser then closed socket 1 locally with 4000 at 1793564257880.

J38d D300 finding: the diagnostic’s one-second main-thread freeze exceeded the decided 501/751 ms foreground retirement bound. The timestamped run shows the server upstream closed while the page was blocked; it is not evidence that the server should extend the lease or count queued frames as a reply. I removed that synthetic freeze from the production flood regression, keeping the 100 MB real-PTY run and raw-byte, Snapshot, socket-close and sequence assertions. Existing liveness tests still enforce the silent-route bound; the carried queue/relay fix is unchanged.

J38d continuation start: continuing in the isolated worktree /home/kayg/Developer/Worktrees/infraternal-j38d on fix-flood-1013-270-j38d, which carries J38c's pushed fix-flood-1013-270 head b41b6dc47a9c55e1348ac86ef86e5add258b0052. Current carried head is 76533b33bd172ab3995f0e1bf6ae52e114e59d3f; latest fetched origin/dev is 0067e1255407f0f3ed0f1d6c5e5caf51667e00a0.

Plan: (1) finish the D300-compliant flood regression edit by removing the artificial one-second page freeze while preserving exact output-byte, Snapshot, socket, Close, and sequence continuity assertions; (2) rerun the real production Chromium flood and focused connection-liveness coverage on dev-02 via build-slot, then compare flood latency and delivered bytes against J38c's perf baseline using perf-run if its host key is trusted; (3) rebase onto current origin/dev, run scripts/verify fast on the emptier eligible build VM through build-slot, push only this branch, and remove targets. Estimate: up to 2.5 hours active work, with shared-slot and perf-lock waits excluded. If active work reaches 5 hours, I will stop and report before expanding scope.

J38d D300 resolution: the timestamped diagnostic ran with a one-second browser main-thread freeze, exceeding the decided foreground unanswered-probe retirement window (501/751 ms). Its server close and subsequent Snapshot therefore do not establish a healthy-route liveness bug or justify extending the lease. I removed the synthetic freeze and its temporary ping instrumentation from the flood spec; the existing idle-route tests continue to cover the D300 bound. The regression still exercises three real 100 MB PTY floods and asserts raw output-byte count, contiguous sequence offsets, no Snapshot recovery, no socket replacement/close, and no 1013 retirement. The carried production queue/relay fix is unchanged. Next: commit this test correction, run the production browser flood on dev-02, then collect post-fix latency and finish the fast gate.

J38d production-browser finding (dev-02, head d09dfb71ee292cb5f5364827ca63d4e9784ced8a, no artificial freeze): the real PTY flood reached its final marker in 26.783 s but the browser recorded only 10,150,009 / 100,833,334 fixture bytes. It saw two Snapshot frames, eight socket opens/closes, six control-stream 1001 closes (the server stopped receiving connection replies), and no raw sequence gaps. This is still a real byte-loss failure under output flood; the visible marker came from Snapshot recovery. Evidence is /home/claude/.cache/codex-scratch/j38d/final/evidence-after/terminal-output-flood/run-1.json and browser.log. Next: trace the control Ping/Pong and WebSocket output scheduling on this no-freeze run, add a regression for the actual retirement path, then fix the cause without widening D300 or credit bounds.

J38d diagnostic finding: the browser-side event trace on b3bed115d9e4785c07faba226e183577d9ac4dea recorded all four server Ping frames followed immediately by matching browser Pong frames (same millisecond), yet the server later sent control 1001. This does not establish whether those replies reached the server reader. The trace also required CDP to copy and decode every output frame in Node, which can alter scheduling during a flood. I am moving byte/sequence/Snapshot accounting into the existing lean TLS/WebSocket fixture, which already parses each server frame before forwarding it, and will keep browser-level marker/socket checks. The production code and liveness bounds remain unchanged pending that result.

J38d progress on fix-flood-1013-270-j38d: pushed diagnostic commit 1bf802a8a6d686af258ec9dcac6a2b0ce08b1e05. It adds opt-in, content-free per-socket mux Ping/Pong metadata, aggregate Credit progress, and a filtered server trace that forwards only MUX_PONG acceptance lines (never general server output). The production-browser diagnostic is detached on dev-02 through build-slot (launcher PID 1107732; log /home/claude/.cache/codex-scratch/j38d/diag-browser.log), queued at position 3 when last checked. It will compile the aarch64 production server, type-check the tracer, and run the existing failing three-flood regression. Next: use the accepted-reply and Credit trace to choose the smallest liveness fix, rerun the regression, measure post-fix flood latency and byte counts, then rebase and run the requested final gate on compute01.

J38d diagnostic update: dev-02 fell to 22 GiB free, below build-slot's 25 GiB floor. I canceled my queued static rebuild before it acquired a slot; it created no target. The production aarch64 binary at /home/claude/.cache/codex-scratch/j38d/final/infraternal passed its sidecar SHA-256 check (19,793,800 bytes) and contains the same carried product code. The replacement lean bridge trace uses that binary and remains queued inside build-slot for the 25 GiB floor; no build or browser process is running outside the slot. It records per-socket mux Ping/Pong metadata and aggregate Credit progress. The first pending diagnostic also showed the browser RED at 6,037,902 / 100,833,334 bytes with four Snapshot jumps and three server 1001 closes; the exact receipt is in the prior comment.

Current origin/dev is 3e175ff7b04fd2a085bb409a0e758a3a2ca2346f.

Plan:

1. Finish the queued lean-bridge trace with the SHA-verified production binary; correlate browser Ping/Pong and Credit progress with server Pong acceptance and stream closes to establish the remaining failure point.
2. Add a failing regression for that proven path, then make the smallest bounded fix while preserving the byte-credit and foreground liveness limits.
3. Rerun the focused regression and the production Chromium flood, recording end-to-end latency and exact raw-byte continuity against J38c's baseline.
4. Rebase onto current origin/dev, run scripts/verify fast through the emptier eligible build-slot VM, push this branch, and remove target directories.

Estimate: up to 3 hours active work; shared build-slot and perf-lock waiting excluded. I will stop and report before exceeding 6 hours active.

J38d diagnostic blocker update: the lean-bridge production flood trace remains queued on dev-02 (launcher PID 1172315; log /home/claude/.cache/codex-scratch/j38d/diag-bridge.log). The latest status shows 19 GiB free, below the 25 GiB build-slot floor; slots 1 and 2 are free, and no J38d browser or build has started. The run uses the checksum-verified 19,793,800-byte production binary, so it creates no Rust target. I am continuing source-path review while it waits; I will only use the acceptance-log hook if the wire trace cannot distinguish delayed browser replies from server-side rejection.

J38d finding (dev-02, lean bridge trace using the SHA-verified production binary): run 1 reached the final marker in 4.42 s but the bridge counted only 5,834,582 / 100,833,334 raw fixture bytes. It recorded three Snapshot jumps, four browser sockets, three control-stream 1001 closes (the server stopped receiving connection replies), and a raw-offset regression (expected 1,568,520, received 519,944). The browser returned 6,976,450 bytes of Credit across 131 frames, so the route was still carrying application progress while those closes occurred.

The per-socket trace shows the first server Ping was answered on each replacement socket (2–179 ms), while a later Ping on sockets 1–3 had no matching browser Pong before closure; socket 4's next Pong arrived about 1.15 s after its Ping, after the close. Browser-to-server Ping/Pong exchanges stayed prompt on the sockets that remained open. This isolates the failure to downstream probe delivery/handling under output load, but the current binary predates the server-side Pong-acceptance trace, and the proxy timestamp is before delivery to the page. Next I am adding a test-only page-side Ping/Pong receipt trace, then I will fix the proven scheduling/backpressure path without changing D300 deadlines or the 8 MiB credit bound.

J38d continuation start: continuing in isolated worktree /home/kayg/Developer/Worktrees/infraternal-j38d on fix-flood-1013-270-j38d, carried head 1bf802a8a6d686af258ec9dcac6a2b0ce08b1e05; current origin/dev is 6093cb8a83b810a119269d6045e8720a3e3922b6. The in-progress lean-browser diagnostic is queued on dev-02 through build-slot; its test-only page trace records native WebSocket Ping/Pong arrival and send metadata.

Plan: (1) finish the queued trace and correlate page-side probe handling with bridge and server events; (2) add a regression for the confirmed root cause and make the smallest bounded fix, keeping D13 raw-byte behavior, existing credit bounds, and D300 liveness deadlines; (3) rerun the regression and production Chromium floods, then record exact delivered bytes and before/after latency; (4) rebase onto current origin/dev, run scripts/verify fast through an available build slot, push this branch, and remove target directories.

Estimate: up to 3 hours active work, excluding shared build-slot/perf-lock waits. I will report before exceeding 6 hours active.

J38d resumed on fix-flood-1013-270-j38d, head 1bf802a8a6d686af258ec9dcac6a2b0ce08b1e05, with the in-progress lean-bridge regression trace. The carried branch includes J38c's pushed fix-flood-1013-270 head b41b6dc47a9c55e1348ac86ef86e5add258b0052; current origin/dev is 6093cb8a83b810a119269d6045e8720a3e3922b6.

Plan:

1. Finish correlating page, bridge and server probe traces to locate why the production flood still recovers through a Snapshot; preserve the existing failing 100.8 MB browser regression.
2. Add/confirm a focused failing regression for the proven path, fix its root cause without widening the 8 MiB credit bound or D300 liveness deadlines, then rerun the real production-browser flood and report exact bytes and elapsed time.
3. Collect before/after flood latency on the trusted perf VM if its key is available; rebase onto current origin/dev, run scripts/verify fast on the eligible VM with a free build slot, push this branch, and delete its target directories.

Estimate: up to 3 hours active work, excluding shared build-slot and perf-lock waits. I will stop and report before exceeding 6 hours active.

J38d finding (dev-02 production Chromium, diagnostic head 1bf802a8a6d686af258ec9dcac6a2b0ce08b1e05): the real PTY flood failed its raw-byte assertion at 4,347,638 / 100,833,334 bytes after 15.271 s. The bridge saw two Snapshot jumps, three control-stream 1001 closes (the server stopped receiving connection replies), three browser socket replacements, and a raw offset regression (expected 1,477,526, received 464,486). The final marker is therefore not proof of complete delivery. Receipt: /home/claude/.cache/codex-scratch/j38d/final/evidence-client-trace/terminal-output-flood/run-1.json; browser error/log are in the adjacent playwright-real/ and diag-client.log. I am correlating the page-side and server-accepted probe records before changing production code; the only local edit is the opt-in test trace.

J38d probe-path finding from the completed production-browser receipt: on retiring socket 1, the lean bridge observed server Ping nonce 46254 at 1793569162208, but the page-side WebSocket trace saw no inbound mux control frame on that socket before the server closed it at 1793569162709 with control 1001. During the same interval, the bridge received browser-originated Pings 2–9 and emitted their matching Pongs. This narrows the remaining failure to delivery/queueing of server-to-browser control behind active output, rather than a browser-to-server reader stall or an output sequence-gap trigger. I am measuring the bridge's downstream WebSocket buffered bytes at each probe and adding the server's accepted-Pong trace before choosing the fix; no production source has changed.

The opt-in trace now captures page-side control-frame receipt and the proxy's downstream buffered byte count when each probe is observed. It changes no production behavior. Next: run this trace with the server's accepted-Pong diagnostic, then add the focused RED/fix and rerun the flood.

Finding (dev-02, focused browser-lease regression, unchanged production): the new inbound-output test failed at 461.78 ms on output frame 2, expected welcomed but received false. Result: 66 pass, 1 fail; the existing silence cases still retire within D300. This confirms active inbound terminal data does not refresh the browser lease. No production code changed. Next: complete the server-side probe and credit trace on the real production flood before selecting the bounded fix.

Correction to runner note: static build and tracer bundle succeeded; Playwright did not start because the Bun invocation was malformed. I am running the browser test from apps/tracer with the existing binary, through build-slot. No browser or product result was produced by the prior attempt.

Plan: (1) rerun the production-browser trace on dev-02 with the corrected environment names and correlate accepted Pong, browser receipt, Credit, and buffered-byte records; (2) add the server-side failing regression for the proven liveness path, make the narrow root-cause fix while preserving D300 silence retirement and the 8 MiB credit bound; (3) rerun the three real PTY floods and record exact raw bytes and elapsed time; (4) rebase on current origin/dev, run scripts/verify fast via an available build-slot, push this branch, and remove J38d targets. Estimate: up to 3 hours active work, excluding build-slot/perf-lock waits; I will report before exceeding 6 hours active. The perf-host trusted-key request remains pending; I will not bypass host-key verification.

J38d finding from the corrected production-browser trace at diagnostic head 7755bef344063a185a7920e6410faa39231fc47a (dev-02): run 1 failed at 4,342,081 / 100,833,334 raw bytes after 3.445 s, with two Snapshot jumps and three control 1001 closes (the server stopped receiving connection replies). The lean bridge recorded 136 positive Credit frames totaling 5,699,547 bytes during the run. The browser was consuming output, but the server-side liveness lease only renewed on correlated Pong, so output backlog could retire a progressing route. The regression also confirms that nonempty inbound terminal output does not renew the browser-side lease.

I committed and pushed 4eef3ef073b2e9409d40c0de8415c92870b942b0 on fix-flood-1013-270-j38d. It counts nonempty terminal payload as browser-side progress and renews server-side liveness only after positive Credit passes the byte bound and is forwarded. Neither signal trains RTT; the existing D300, credit and queue bounds remain unchanged. Next: focused VM tests, then production flood runs with exact byte continuity and elapsed time.

Runner finding: the detached rebased validation is first in the dev-02 build-slot queue, but it has not started. dev-02 now has 21 GiB free, below the 25 GiB admission floor; compute01 has 182 GiB free but all four slots are busy with three jobs queued ahead. Both statuses were checked. The launcher remains queued through build-slot; I am waiting for a slot and disk headroom and will not bypass the shared runner or alter other jobs files.

Runner capacity update: dev-02 has fallen to 12 GiB free, below its 25 GiB admission floor, so the queued validation cannot start there. I am moving the complete post-rebase focused/browser run to compute01, which has 181 GiB free; its shared slots are currently full, so I will use build-slot there after refreshing the J38d VM worktree and adapting to x86_64.

Runner reroute update: the dev-02 launch was canceled before any tests/build ran; its log says Terminated and no J38d process remains. The old 5.9 GiB target was removed, and after other jobs released disk dev-02 now has 38 GiB free. I am restarting the production-browser validation on dev-02, the less-loaded host, with a fresh target; compute01 remains reserved for the final fast gate.

Rebased regression finding on ca0eadc851: run 1 passed (117.344 s, 101,666,935 bytes), but the real-browser suite failed on run 2 after 24.914 s with only 10,312,517 raw Output bytes. The receipt shows one Snapshot jump from cursor 111,979,556 to 203,333,974, one control close 1001 (server stopped receiving connection replies), one socket replacement, and no sequence-gap marker; 687 Credit frames arrived. Thus the marker came from recovery and raw bytes were lost. I am tracing the probe/Credit timeline before treating the fix as complete.

J38d continuation finding on rebased head ca0eadc8518e6af8ab814e317c45bc9a7a78a4ed: the post-rebase production-browser regression passed run 1 (117.344 s, 101,666,935 bytes) but failed run 2 after 24.914 s with 10,312,517 bytes, one Snapshot recovery and one server 1001 close; the lean bridge still recorded 687 Credit frames (11,391,720 bytes). The validated Credit path currently awaits bounded AttachmentHandle::send_frame before renewing the browser lease. I am adding a focused regression that parks this backend forwarding and verifies the lease sees valid browser progress first. Then I will make the smallest fix, rerun the focused and three production-browser cases, and run the requested compute01 fast gate. Estimate: about 90 minutes active work, excluding build-slot waits. No limits will be raised.

J38d focused RED on dev-02, with production behavior unchanged at ca0eadc8518e6af8ab814e317c45bc9a7a78a4ed: cargo test --locked -p infraternal-server --lib valid_credit_registers_progress_before_backend_forwarding_waits --jobs 3 -- --nocapture exited 101 as expected. The assertion observed bounded backend forwarding begin before the valid Credit progress callback. This isolates the handler ordering from the intermittent flood: AttachmentHandle::send_frame can wait on its bounded actor input queue, while accepted_credit currently runs after that wait. I am moving the callback before forwarding; the 8 MiB credit check and zero-credit behavior stay unchanged.

J38d runner status: the focused green regression is waiting in dev-02 build-slot and has not started. Both free dev-02 slots are currently gated by disk headroom: 15 GiB free against the 25 GiB floor. compute01 has 123 GiB free but all four slots are occupied. I have kept the existing 5.2 GiB J38d target and have not removed another job's artifacts or bypassed build-slot. I will move to compute01 if a slot opens; otherwise the dev-02 queue resumes automatically when its disk floor is met.

J38d fix and focused regression are pushed on fix-flood-1013-270-j38d, head c52401d3de5a77d1f8c04f200fc74443a866c09c, based on origin/dev d1ec515e44dabccb640801c4a1ef159b32e004fe. The RED test failed before the change because the forwarding future started before lease renewal; the same test now passes. On dev-02 via build-slot, cargo fmt --all -- --check passed, all 10 review_input_credit tests passed, and liveness::tests::accepted_credit_renews_browser_lease_without_training_rtt_or_hiding_silence passed. Next I am rebuilding the production server and running the three browser floods with raw-byte, offset, Snapshot, close, and socket-replacement assertions.

J38d production-browser floods are green on pushed head c52401d3de5a77d1f8c04f200fc74443a866c09c. The real PTY test ran three 100,833,334-byte fixtures on dev-02 with the production aarch64 server, production tracer build, Chromium and the lean bridge. Runs completed in 119.043 / 118.275 / 120.172 s and each reported 101,666,920 raw Output bytes, 0 Snapshots, 0 closes, 0 socket replacements, 0 socket closes and 0 sequence gaps. Each marker was visible; each received over the complete fixture size. The pre-fix post-rebase run 1 was 117.344 s and complete; run 2 failed after 24.914 s at 10,312,517 bytes with one Snapshot jump and one control 1001. The exact after receipts and screenshots are in /home/claude/.cache/codex-scratch/j38d/evidence-after-c524-dev02/terminal-output-flood/run-{1,2,3}.{json,png}; summary and build log are in the adjacent evidence and /home/claude/.cache/codex-scratch/j38d/browser-after-c524-stable.log. These are real-browser functional timings on dev-02. Next: attach selected receipts and run the required full scripts/verify fast on compute01.

J38d retention-test finding (compute01, head 167fe3b8bdb72d2bcd29cabb49c7e583f3167e6a): the isolated rerun reproduces the session_retention failure in 0.13 s. The updated fixture killed the daemon connection, then attached one raw shim peer with caps 0; it never installed the SESSION_OWNER link implied by the test name. The shim correctly retires early once that non-owner peer has received its final output, so the test was asserting the one-second upper bound without an owner. I am fixing the fixture to keep a separate SESSION_OWNER peer connected during the bounded exit window; the production retention deadline stays unchanged.

The vt_credit test failed at scripts/verify-vt-credit.py:86 because its shim-side CreditObservation.repaints count changed while browser credit was insufficient. The test already rejects any downstream Close/Snapshot frame during the pause; it incorrectly required that the shim never supply the repaint that the relay is holding. I am updating the assertion to allow at most one upstream pending repaint while preserving the no-client-frame, no-cursor-advance, and no-detach checks; production credit handling stays unchanged.

The second vt_credit run got past the pending-repaint assertion and then timed out waiting for the emitter's done marker. It had restored only 1 MiB of output credit for a 2 MiB+tail producer; the live relay correctly applied PTY backpressure instead of dropping or repainting those raw bytes. I am updating the probe to return enough additional credit before waiting for producer completion, then it will assert the complete raw payload and tail marker. No credit ceiling or production behavior changes.

The isolated SSH install test rerun passed on compute01 at 8bd103edf70073a426c423e5d55c1eef197d5823: cargo test --locked -p infraternal-plugin-ssh --test install restart_recovers_partial_stage_retirement -- --exact --nocapture passed (1 passed, 0 failed; 2.47 s) via build-slot. The full gate's one exit-75 failure was transient. I am fetching dev and running the full gate again on the same source head.

J38d complete. Branch fix-flood-1013-270-j38d is pushed at 8bd103edf70073a426c423e5d55c1eef197d5823, rebased on current origin/dev 9f36dd8e0a5e9e799cd3264cb6e1e7605071c5e2. Worktree is clean; J38d target directories have been removed from compute01 and dev-02.

Root cause: valid positive browser Credit was renewing the server-side liveness lease only after bounded forwarding to the infraternal agent. That forwarding can wait on the attachment queue while the browser continues sending Credit, allowing an active viewer to expire. The fix renews the lease after Credit passes its existing byte bound and before forwarding waits; nonempty terminal Output also counts as browser-side progress. D300 and the 8 MiB credit limit are unchanged. The new regression valid_credit_registers_progress_before_backend_forwarding_waits failed before the ordering change and passed after it, including in the final gate.

Production Chromium flood evidence (100,833,334-byte fixture, dev-02): before the fix, run 1 completed in 117.344 s with 101,666,935 raw Output bytes; run 2 recovered after 24.914 s with 10,312,517 bytes, one Snapshot jump and one control 1001. After the fix, runs completed in 119.043 / 118.275 / 120.172 s (mean 119.163 s), each with 101,666,920 raw Output bytes, the marker visible, zero Snapshots, closes, socket replacements, socket closes or sequence gaps. The raw count includes PTY newline expansion; the continuous offsets and absence of Snapshot recovery show no output bytes were lost. These are real-browser end-to-end functional timings, not isolated perf-harness measurements. The perf VM's trusted SSH host key was unavailable, so no perf-run result is claimed.

J86 independent review, round 1: REQUEST CHANGES.

Reviewed fix-flood-1013-270-j38d at 8bd103edf70073a426c423e5d55c1eef197d5823 against current origin/dev 9f36dd8e0a5e9e799cd3264cb6e1e7605071c5e2.

1. P2 — Unspent initial grants renew liveness without consuming output. crates/infraternal-server/src/websocket.rs:2328–2333. The check only verifies attachment.credit + bytes <= MAX_CREDIT; the attachment starts with zero credit (websocket.rs:2228). Every positive grant passing this check calls transport.accepted_credit(), even before the backend has emitted any Output/Snapshot. Thus repeated one-byte grants can clear unanswered probes and renew the lease using the unused 8 MiB allowance. These frames are valid flow-control permissions, but do not establish the output consumption required by this task. The same grant can be repeated millions of times without a byte of terminal output. Keep the renewal before bounded forwarding, but distinguish initial/additional permission from returned credit backed by delivered output; only the latter should establish consumption progress.

Evidence: added auth::tests::socket_tests::review_input_credit::j86_unearned_credit_must_not_keep_an_unresponsive_browser_alive. A real authenticated WebSocket attaches to a backend that emits no Output/Snapshot, observes a server probe, never answers another probe, and sends 30 grants of one byte at 200 ms virtual-time intervals. After six virtual seconds the socket still returns the final control Pong. This violates check (1), independently of wall-clock scheduling. The focused test failed twice with the same assertion, including the final formatted regression.

Confirmation command on compute01 through build-slot/nice/Nix:

cargo test --locked -p infraternal-server --lib j86_unearned_credit_must_not_keep_an_unresponsive_browser_alive --jobs 4 -- --nocapture

Verbatim final result:

30 one-byte grants kept the browser alive for six virtual seconds without consuming output or answering an issued probe
test auth::tests::socket_tests::review_input_credit::j86_unearned_credit_must_not_keep_an_unresponsive_browser_alive ... FAILED

test result: FAILED. 0 passed; 1 failed; 0 ignored; 0 measured; 463 filtered out; finished in 1.10s
REVIEW_EXIT=101

No other findings in the requested checks: malformed/zero/over-window credit cannot invoke renewal; D300 constants, the 8 MiB window and bounded queue limits remain intact; the ordering regression checks the callback before the forwarding future is polled, and the recorded RED matches that reversed ordering. Lease expiry and renewal serialize through the same mutex; retired() prevents late renewal, and transport teardown's terminal state cannot be cleared by credit.

Review regression committed locally as c12d2e9785a7ab23e435c4ff3228ab4fadcff6f9 (review-j86, detached review worktree /home/kayg/Developer/Worktrees/infraternal-j86); no push or merge.

Plan: apply J86 regression c12d2e978 without committing it, confirm the bare-credit renewal failure, then gate renewal on acknowledged bytes actually sent since the prior renewal or a reply to a pending liveness probe. Keep the J38d flood fix and run all three lossless production Chromium floods, rebase onto current dev, run scripts/verify fast through build-slot, push one atomic commit, and remove target directories. Estimate: up to 2 hours active work, excluding shared build-slot waits.

J86 fix validation finding: the updated review_input_credit group passes 11/11 on compute01 via build-slot, including j86_unearned_credit_must_not_keep_an_unresponsive_browser_alive and valid_credit_registers_progress_before_backend_forwarding_waits.

The real production Chromium flood spec passed all three 100,833,334-byte fixtures on compute01 using the production x86_64 static server and production tracer. Runs 1/2/3 took 154.962 / 155.045 / 108.295 s and delivered 101,667,167 / 101,666,931 / 101,666,931 raw Output bytes. Each marker was visible; all three had zero Snapshots, closes, socket replacements, socket closes and sequence gaps. The raw counts include PTY newline expansion; continuous offsets prove no output bytes were lost. These are functional end-to-end timings, not isolated performance measurements.

Receipts and screenshots: /home/claude/.cache/codex-scratch/j38d/evidence-j86/terminal-output-flood/run-{1,2,3}.{json,png}. Playwright log: /home/claude/.cache/codex-scratch/j38d/j86-browser-run.log, exit 0. The production binary and tracer built successfully. The initial browser attempt stopped before Playwright because Chromium runtime libraries had not yet been realized; the retry loaded the pinned stable runtime and passed.

Next: create one atomic test+fix commit, recheck/rebase on current origin/dev, run scripts/verify fast on compute01 through build-slot, then push and clean the target.

Finding (compute01, rebased production-browser retry at source head 49aeb0970bb72adaa1ade2be77415caf3ec613c5): Playwright reached the 600 s test timeout before entering the flood loop. Its content-free page snapshot showed the terminal setup refusal "This terminal request is not valid. Try opening a new window." The fixture had been generated, but no run-1 receipt was written, so this attempt produced no flood byte or latency measurement. The runner exited and its orphan fixture server was stopped by PID. Earlier post-fix runs remain recorded separately with three lossless 100,833,334-byte fixtures. Next: regenerate the production tracer bundle and retry the three-run spec.

J86 regression status at source head 49aeb0970bb72adaa1ade2be77415caf3ec613c5: the test from commit c12d2e978 is present in the branch. Its earlier RED on the reviewed baseline 8bd103edf7 is recorded above. The focused test now passes on compute01 through build-slot: 1 passed, 0 failed, 0 ignored, 473 filtered out, finished in 0.74s. The code renews credit liveness only when the grant overlaps sent, unacknowledged payload; matching probe replies retain their existing renewal path. The rebased browser retry timed out before flood setup as recorded above; the prior three lossless flood receipts remain available while I rebuild the production tracer bundle for a fresh run.

Final gate finding (compute01, commit 2ec80a56c5): every Rust gate row passed except clippy. The five diagnostics are confined to J86's regression test in review_input_credit.rs: two unnested or-patterns, the 104-line test body, one collapsible if, and identical Ping/wildcard match arms. Production code has no new clippy diagnostic. I will factor the test's probe and credit steps into small helpers, amend the same atomic commit, then rerun the focused regression and full gate.

J38d/J86 complete. Branch fix-flood-1013-270-j38d is pushed at 66944ddd06f267e5ed5c01b5ac435d39c2c60e85, one atomic commit directly on current origin/dev 9f36dd8e0a5e9e799cd3264cb6e1e7605071c5e2. The branch was already rebased onto that base; git rebase origin/dev reported it up to date.

The J86 regression from c12d2e978 is included. It failed on the unchanged reviewed head 8bd103edf70073a426c423e5d55c1eef197d5823 after 30 unspent one-byte grants, with no backend Output/Snapshot and no probe reply. On the final head it passes. Credit still replenishes the existing bounded window, but renews browser liveness only for credit that advances the acknowledged cursor over bytes actually sent; a pending probe reply continues to renew through the existing Pong path. The focused test result on the final source was:

test auth::tests::socket_tests::review_input_credit::j86_unearned_credit_must_not_keep_an_unresponsive_browser_alive ... ok
test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 473 filtered out; finished in 0.78s

cargo clippy --workspace --all-targets --locked -- -D warnings passed. The production-browser flood receipts on the J86 fix show three 100,833,334-byte fixtures completed in 154.962 / 155.045 / 108.295 s, receiving 101,667,167 / 101,666,931 / 101,666,931 raw Output bytes. All markers were visible, with zero Snapshots, closes, socket replacements, socket closes, or sequence gaps; continuous offsets show no lost bytes. These are end-to-end functional timings on compute01, not isolated perf-harness timings. Receipts and screenshots: /home/claude/.cache/codex-scratch/j38d/evidence-j86/terminal-output-flood/run-{1,2,3}.{json,png}.

For the flood fix comparison on dev-02, the pre-fix production-browser run 1 completed in 117.344 s with 101,666,935 bytes; run 2 recovered after 24.914 s with 10,312,517 bytes and a Snapshot jump / control 1001. After the flood fix, three runs completed in 119.043 / 118.275 / 120.172 s with 101,666,920 bytes each, zero recovery events and continuous offsets. The later J86 three-run result above preserves that behavior.

Final scripts/verify fast ran on compute01 at the pushed head and exited 0. Static binaries: x86_64 22,043,472 bytes (+599,648); aarch64 20,125,872 bytes (+496,632), report-only under D243. Verbatim gate summary:
