a683e3ff568f151345d2212bd545e367a5ceb5d9 (PR-G #2509, squash-merged at
2026-11-01T00:13Z).
git rebase --onto origin/main 3ee50e05 feat/relay-surface replayed 24 commits without
conflicts. The PR changes 54 files, below the 150-file review cap.

The rebased head and previously verified f4f5941f1d9095f7e97746e209f7310d2939a68a
have the identical tree 222515190368b6ab41f883305ec1ac1b29406afb;
git diff --exit-code f4f5941f HEAD returned 0.

Validation on the new head (2026-11-01, TMPDIR=/var/tmp):

• timeout 300 bun install --frozen-lockfile: exit 0, no changes.
• timeout 300 bun run typecheck: exit 0.
• timeout 900 bun test --timeout 15000 server/relay src/lib/relay shared relay scripts/ci-browser.test.ts scripts/relay-shell-qa-versions.test.ts:
  exit 0, 798 pass / 0 fail, 9528 assertions in 40 files (134.34 s).
• The bounded headroom gate passed with 38 GiB available and load1 56.88; immediately before
  fast checks the host had 38 GiB available and load1 53.68.
• First CHECK_DIR=/var/tmp/ck-prh timeout 1800 bun run check fast: exit 1, run
  c1898ee1-a85c-498f-b6d4-bc7cc2bb4d85, testedSha == HEAD, source unchanged.
  Workflow syntax, generated types/themes, typecheck and build passed.
  Unit tests: 10339 pass / 3 fail / 41 skip in 648 files. Every failure:
  • src/lib/relay/transport.test.ts: "loads a real file larger than the mux session buffer as a
    bounded blob", 30000 ms timeout, followed by unhandled Relay body failed /
    MuxStreamError: upstream_lost during cleanup.
  • scripts/relay-ios-sim.test.ts: "finishes every step when eamac's half never reports
    WebDriverAgent ready", 30000 ms timeout.
  • server/codex-processes.test.ts: "weighs another loaded conversation's answer in any layout
    Codex shows it in: a link by its target, a table, an escape decoded", 20000 ms timeout.
    The orchestrator independently reproduced this Codex failure on untouched main a683e3ff.
• Each failing file rerun alone once with
  TMPDIR=/var/tmp timeout 600 bun test --timeout 60000 <file>:
  transport 35 pass / 0 fail (49.95 s, failed test itself 1763.92 ms), Simulator cleanup
  2 pass / 0 fail (12.59 s), Codex 137 pass / 0 fail (23.22 s); all exit 0.
• Transport's test and implementation blobs are identical at 3ee50e05 and this head.
  The parallel-run timeouts did not reproduce alone. Host contention is consistent with the
  observations (29 GiB available and load1 120.86 during the first run), but is not a proven
  sole cause; no source or test timeout was changed.
• Second whole CHECK_DIR=/var/tmp/ck-prh timeout 1800 bun run check fast: failed under
  host load1 100-380 with the same three timeout cases above; each file passed alone.
  No source or timeout was changed.
• Publication check on 2026-11-01:

  exit 0, run 13379c7a-c547-48ad-a300-65ea003c5122, status success/verified,
  source unchanged, and revision.testedSha == HEAD == 6f2e5e19fc2eba1d00ea5da50499507fe9e57fc4.
  Workflow syntax, generated types/themes, typecheck and build passed. Unit tests:
  10342 pass / 0 fail / 41 skip in 648 files. Launch headroom was 64 GiB available
  at load1 14.69. No rerun was needed; /var/tmp/ck-prh3 was removed after the
  receipt was recorded.

Same-tree evidence carried forward from the f4f5941f restack below:

• Standalone shell QA twice (CHECK_DIR=/var/tmp/ck-ph3 and /var/tmp/ck-ph4,
  bun run check run bun scripts/relay-shell-browser-qa.ts): both exit 0,
  including forged-link section (g2), with 25 CSP-clean pages.
• Mutation in a scratch worktree: allowing a forged link on re-open made (g2) fail
  waiting for identity-changed, exit 1. The mutation was reverted and scratch removed.
• Full relay e2e:
  FFMPEG=$(bash scripts/ci-ffmpeg.sh) CHECK_DIR=/var/tmp/ck-pe2e bun run check run bun scripts/relay-e2e-regression.ts:
  exit 0, PASS relay media browser QA and PASS relay end to end.
  The earlier attempt without FFMPEG failed to find ffmpeg after shell QA passed.
• bun run build:shell: exit 0; i18n plus four convention test files: 80 pass / 0 fail.
• Not rerun after this tree-identical rebase: standalone shell QA, mutation, full relay e2e,
  build:shell, and standalone i18n/convention tests.
• Not run in this publication pass: check full, separate integration/browser lanes,
  relay panel regression, native Windows/Mac/iOS/Android, and live relay. CI and CodeRabbit
  run after publication.
• Independent restack gate:
  .omo/evidence/relay-restack-f4f5941f-gate-review.md approves the bounded restack.
  It independently passed shell QA and relay-panel QA on f4f5941f, verified the
  forged-link assertions against PR-G, and reproduced the Codex timeout on untouched
  main a683e3ff. Its approval does not certify green fast checks or CI.

PR-G cleanup receipts: feat-relay-client was clean at

git merge-base --is-ancestor 2c7227c5 3ee50e05 returned 0.
Removing only its named worktree and deleting feat/relay-client each returned 0.

Earlier: restacked onto PR-G 3ee50e0 (2026-11-01, historical)

Head: f4f5941f1d9095f7e97746e209f7310d2939a68a; base: origin/feat/relay-client 3ee50e05 (PR-G #2509 after the merge pass's round 2:
aa834cb0 forged pairing links refused every time, 3ee50e05 boot test by behaviour). Local only; no push or PR.
Rebased with git rebase --onto origin/feat/relay-client 2c7227c5 feat/relay-surface: 24 commits.

Conflict: scripts/relay-shell-browser-qa.ts at 019e0ad6 (H's restructure into the exported
relayShellQa(tree), now 3886a6c1). Resolved by keeping H's structure and porting aa834cb's QA:
OTHER_KEY/OTHER_ID = deriveServerId(OTHER_KEY) (a saved PC with a mismatched key is now refused);
new section (g2): a forged link (this PC's id, another key) gets identity-changed in its own words
("This link is not Desk PC's"), no Pair, no Forget, 0 sockets, nothing saved; pasted again into the
open tab, the same; with the PC's own key saved, refused and that key untouched; a forged saved key
warns on the PC's scope with 0 sockets and Forget removes it; (j) picks the Laptop row by text, since
the list is in IndexedDB key order. aa834cb's (d) pairing-socket wait was already in H's (d). Every
earlier merge-pass assertion (g: Forget only forgets, unreachable-relay offer minted first) kept.
Gate add-on folded into 3886a6c1 (fixup + autosquash): the header no longer says the browser lane
runs the script "with no other step"; it runs through relay-e2e-regression.ts, which calls
relayShellQa with its own tree. H's own code (Settings relay group, reset identity, devices/settings
i18n, DESIGN) touches no phone-side forget/identity-changed/forged state: no adaptation needed.

Validation on f4f5941f (TMPDIR=/var/tmp):

• bun install --frozen-lockfile: no changes. bun run typecheck: exit 0. bun run build:shell: exit 0.
• timeout 900 bun test --timeout 15000 server/relay src/lib/relay shared relay scripts/ci-browser.test.ts scripts/relay-shell-qa-versions.test.ts: 798 pass / 0 fail in 40 files.
• src/lib/i18n.test.ts + the four conventions.test.ts files: 80 pass / 0 fail.
• Shell QA alone twice in a row (CHECK_DIR=/var/tmp/ck-ph3, then ck-ph4, bun run check run bun scripts/relay-shell-browser-qa.ts): both exit 0, (g2) passed, 25 CSP-clean pages.
• Mutation (scratch worktree): a forged link refused only the first time (pairable on re-open) ->
  shell QA fails in (g2) waiting for identity-changed (check exit 1). Reverted; scratch removed.
• Full relay e2e after the headroom gate (42 GB available, load1 28.8):
  FFMPEG=$(bash scripts/ci-ffmpeg.sh) CHECK_DIR=/var/tmp/ck-pe2e bun run check run bun scripts/relay-e2e-regression.ts: exit 0,
  PASS relay media browser QA, PASS relay end to end. (A first attempt without FFMPEG stopped at
  Executable not found in $PATH: "ffmpeg" in the media part, after the shell QA passed.)
• Skipped: check full, relay panel regression, native Windows/Mac/iOS/Android, live relay. check fast ran once on I.

Earlier: restacked onto final PR-G 2c7227c (2026-11-01, historical)

Head: 005cc753219152bf779dc4e6f7d4324117d64f8b; base: origin/feat/relay-client 2c7227c5 (PR-G #2509 final, awaiting merge). Local only; no push or PR.
Rebased with git rebase --onto origin/feat/relay-client 55e9c541 feat/relay-surface: 24 commits
(was 25; eb55f656 dropped because the merge pass's f6a0593c makes the same fix).

Merge-pass decisions kept:

• No relay-skew CI job and no scripts/relay-skew.ts (ed547aa). H no longer re-adds the job in
  fb56fc4e/683a7211/9596600b; MIN_SERVER_VERSION stays 0.4.21. H keeps the product code
  src/lib/relay/skew.ts and the hand-run relay-e2e-regression.ts --skew <tag> /
  RELAY_E2E_SERVER_DIR; comments no longer name relay-skew.ts. The ffmpeg-step test now expects
  one "Pinned ffmpeg" step (fixup into 3b04ad32).
• Shell QA in the browser lane (f6a0593): relay-shell-browser-qa.ts keeps building the shell into
  its own temp folder and runs in the lane once, inside relay-e2e-regression.ts (which runs the
  shell and media suites after its journey); no second run_script line. The merge pass's fixes are
  ported into H's exported relayShellQa: the unreachable-relay offer is minted before the relay
  stops, and section (g) checks that Forget only forgets (forgotten screen, key gone, 0 sockets, no
  Pair; a fresh QR pairs).
• fcb657e / f5aee35 / 0b44734 client behaviour is untouched by H; H's QA passes against it
  (forgotten screen; key saved only on AUTH_OK; worker refuses unrequested file requests and the
  media QA's isolation checks still pass in worker and blob mode).

Conflicts: src/lib/i18n.test.ts (union of G's files list and H's RelayPanel entry);
scripts/ci-browser.sh (merge pass's shell QA line plus H's media/e2e, later H's single e2e line);
scripts/relay-browser-bridge.ts (same signature; merge pass body, H doc comment);
scripts/relay-shell-browser-qa.ts (fb56fc4e/6e666783: merge pass's file; 683a7211: H's
restructure with the merge pass's fixes ported; eb55f656: dropped); .github/workflows/ci.yml
(683a7211, 9596600b: relay-skew hunks dropped, H's browser-lane build:shell and pinned ffmpeg kept);
scripts/ci-browser.test.ts (H's manual-list removal).

Validation on 005cc753 (TMPDIR=/var/tmp):

• bun install --frozen-lockfile: no changes. bun run typecheck: exit 0. bun run build:shell: exit 0.
• timeout 900 bun test --timeout 15000 server/relay src/lib/relay shared relay scripts/ci-browser.test.ts scripts/relay-shell-qa-versions.test.ts:

• src/lib/i18n.test.ts + the four conventions.test.ts files: 80 pass / 0 fail.
• Shell QA alone, CHECK_DIR=/var/tmp/ck-ph1 bun run check run bun scripts/relay-shell-browser-qa.ts:

• Relay panel browser regression (checkRelayPanel from scripts/relay-panel-regression.ts in an
  isolated check run, as ui-regression.ts calls it): exit 0, PASS.
• Full relay e2e after the headroom gate (41 GB available, load1 36.7):

Gate finding 1 is fixed in 0d363b4a, the fixup/autosquash replacement for a26a9c2d.
The shell-fixture commit 367d3e98 is now eb55f656. I was restacked onto this head and is
ba8c8307357d3756b6ab0ae639cf5e3ec1365e4e. G and PR-F's base are unchanged.

Old H 7ca1749d was replayed from cafc2c28 onto new G without Git conflicts. PR-F's head is e3686f21. The owner-only/direct-only controls, sign-in deadline, per-device cap, sign-in-order eviction and no control rate limit are retained.

PR-E #2499 (b0abd589, proof c8a4fe8b) is authoritative. Every PC control/data socket sends proof=1&public_key, answers the per-socket X25519/HMAC challenge, and uses the key-derived server_id. PR-F's shared proof helper and permanent-refusal constants are retained. Relay proof expiry stays 4401; the PC retries timeout/ambiguous 4401, capacity 1013 and local challenge-order 4000 with backoff. Only control 4401 naming server key does not match server_id or invalid server key stops retries. Sixteen proofs may wait (oldest displaced); eight answered clients hold slots and four unanswered clients may wait.

feat(relay): turn on the Ovis relay from Settings, open its links in the apps, and prove it end to end

Summary

PR-H of the e2ee-relay plan (todos 20, 21, 23, 25, 26), plus the relay fixes held back from PR-E
to PR-G. This is the PR that lets a user turn the relay on. Based on main a683e3ff
after PR-G #2509 merged: 24 commits and 54 files, below CodeRabbit's 150-file cap.

• Settings relay panel (todo 20, 26). Settings -> Phone & devices gets a relay group
  (src/components/RelayPanel.tsx, src/lib/useRelay.ts): a switch that starts and stops this
  PC's link, the state in words (Off, Connecting, Online with how many phones are connected, Error
  with the server's sentence, Blocked by serve-only or an unreadable identity), the pairing QR with
  its countdown and New code, and Reset relay identity behind a confirm. The QR and the Devices
  group share one pending pairing code. A watching device or Portal visitor sees the state and a disabled switch,
  with no offer and no reset. The hosted shell shows no group. Devices gets a "via relay" pill.
  Default Portal watch visitors get 403 read_only; a saved drive invitation gets
  403 owner_only (the watch guard runs first in server/dispatch.ts:223-243).
  Every relay mutation requires a direct connection
  (403 local_required through the relay). The panel follows the same Portal read-only rule as
  its neighboring Portal panel. Beside the disabled switch, it explains that only the PC's owner
  can control the relay using a direct connection, and asks them to open Ovis on the PC or at its
  direct address. English uses the source key; Korean, Japanese and Chinese are in devices.*.
  The browser regression verifies the explanation is visible and nonempty for Portal visitors,
  absent for the direct owner both offline and online, and no owner-only POST is issued.
  scripts/relay-panel-regression.ts (in ui-regression.ts) checks the panel against a local Bun
  relay and the real hosted shell boot (todo 26).
• Native links (todo 21). The iOS and Android apps open a relay pairing link
  (https://app.ovis.sh/s/<server_id>/#offer=...), scanned or pasted, as the WebView's first page.
  An offer on another origin, or one naming a different PC than its path, is refused on the
  connect screen. Relay PCs share the shell origin, so the native stores save each one by scope
  URL. Dot segments (plain, encoded or double-encoded), encoded slashes and backslashes never
  match a scope (Android PCStore.cleanPath + PCStoreTest; iOS ScopePath.swift +
  app/ios/ScopePathCheck).
• End-to-end regression (todo 23, 25). scripts/relay-e2e-regression.ts drives two isolated
  PCs, one Bun relay and the real hosted shell across origins: pairing, terminal I/O, roster,
  reconnect without replay, revoke, every shell state, push rotation, and service-worker and blob
  media with isolation. CI's browser lane builds the shell and fetches a pinned static ffmpeg
  (scripts/ci-ffmpeg.sh, which fails the lane if the fetch fails, M1). The relay shell and media
  QA leave PR-G's manual list in scripts/ci-browser.test.ts. scripts/relay-ios-sim.sh is the
  Simulator script (with bounded cleanup). Todo 25 made the blob-mode media run deterministic.
• Transport parity. Every API request of the hosted shell goes through the relay, including
  relay-control requests and the copy-on-select preference.

What users see

• A PC owner can now turn remote access on in Settings and scan the QR with a phone, or open the
  link in the Ovis iOS/Android app. Before this PR the only ways in were POST /api/relay/start
  or plugin pair's hint.
• The hosted shell still has to be served from somewhere. app.ovis.sh and relay.ovis.sh
  come from CI deploys whose Cloudflare setup the owner has deferred (F3). Until then only a
  self-hosted relay and dist-shell/ work.
• Changelog fragments: changelog.d/relay-server-proof.md, relay-bun-limits.md,
  relay-transport-parity.md.

Security notes

• Authoritative server proof is inherited from E and F. E supplies the key-derived ID, per-socket challenge and answered-client slot rules. F answers the proof and keeps retrying transient refusals. H drops its duplicate relay implementation and keeps the proof-aware scripted PCs and forged-proof/concurrent-reconnect coverage. Prerelease random-ID identities remain refused unchanged until explicitly reset.
• Self-hosted (Bun) relay limits by default (5c588379, 4324fa9e, 44ecabcb).
  relay/bun-limits.ts: 120 connections a minute per address, 600 globally, 1024 sockets, 256
  rooms, 4096 tracked addresses. Each limit can be set by flag or env. The per-address budget fits
  file browsing in the media QA (c705aab3). Tests drive the limits with a test clock.
• M2 retry semantics moved to F (feee83f3). E keeps expiry/timeout on 4401; the PC retries those and ambiguous proof refusals, 1013 capacity closes and local 4000. Only a definitive key/server-ID refusal on the control socket stops reconnecting. H drops the redundant M2 replay rather than changing E.
• This PR changes authentication (relay admission) and a workflow (ci.yml browser lane), so it
  waits for a real review. If CodeRabbit skips it, a code-review agent's findings go in a PR
  comment.

Throughput and the latency trade-off (todo 27, PR-C)

The bulk window was widened in PR-C. Measured at a 50 ms RTT, relay file transfer went from 0.32
to 6.36 MB/s (at 100 ms RTT, 0.16 to 3.23 MB/s). The cost: with zero RTT and a 64 MiB transfer in
flight, terminal echo p95 rises from 1.25 ms to 26 ms (above the 1.5x-of-idle target). At a real
relay RTT of 50 ms the loaded/idle ratio is 1.02x. This PR makes the relay reachable from the UI,
so this is the first point where users can hit that case (typing while a large video loads), and
the delay stays below a perceptible typing lag. Evidence:
.omo/evidence/e2ee-relay/task-27-throughput.md, perf-relay-throughput.md.

All H validation below ran on clean eb55f656d431b91456515a95e21744ed2b14163e
after fixup/autosquash, with explicit timeouts and TMPDIR=/var/tmp.

Captures were inspected at 390x1000 and 1440x1000, light/dark. The whole explanation is
readable beside its disabled control with no clipping or overlap; direct-owner absence is
covered by the regression. Captures and their temporary driver are removed after recording

LSP remains unavailable because TypeScript 7.0.2 supplies no tsserver.js; the repository
typecheck passed. Browser checks used the Node PTY fallback. Native platforms, check full,
and full relay e2e were not rerun for this gate fix. Earlier e2e evidence is historical.
The disposable sessions were stopped by the runner; owned check and capture scratch is removed.

PR-F #2504 restack (2026-10-31, historical)

Adaptations: Settings passes auth.via === "portal" into RelayPanel's existing read-only path; comments and DESIGN.md describe every relay mutation as direct-only. The existing API-error rendering still displays a refused request's detail. The panel browser regression supplies Portal auth and an owner_only refusal seam and verifies a disabled switch, no pairing offer/reset and zero relay mutations. The stopped-relay shell fixture now obtains its offer before stopping the relay, since PR-F rejects new offers in error with 409 relay_offline. All normal fixtures sign in before the new 15-second deadline; the deliberate unresponsive PC is scripted separately. No deadline or cap bypass was needed.

Frozen install and typecheck exit 0. Requested relay/CI fixture tests ran once: 789 pass, 0 fail, 9451 assertions in 40 files, isolated run 93a2a2f4-ffc6-4c7a-abeb-04748021e838. Direct-app build and build:shell exit 0. Panel browser regression plus Portal read-only captures at 390/1440 in light/dark pass (run 852deb11-e3c1-49c5-996a-2b6bfa5f0c46); captures were inspected, with no blank or overlapping relay panel.

Standalone shell QA ran once: run ffd72114-6141-4494-8ab6-72974f0e5b19, exit 0 in 29620 ms. It covers exact clock boundaries, pairing/revoke/rename, Settings hidden in the real shell, push rotation and version skew, 24 CSP-clean pages.

Full relay e2e ran once with pinned FFMPEG=$(bash scripts/ci-ffmpeg.sh) timeout 1800 bun scripts/relay-e2e-regression.ts, exit preserved and printed as EXIT=0, inside the isolated check runner. Headroom gate passed immediately at 44 GiB available, load1 42.79. Run 5bc07794-3bdb-4f83-a527-278d3d8a74b1, exit 0 in 73942 ms: PASS relay media browser QA and PASS relay end to end. Terminal, roster, reconnect/no replay, revoke, worker/blob isolation, remote media, PDF and MP4 seek/Range pass.

The runs verified unchanged source on rebased a1de10a2 plus the recorded adaptations, before committing them as a26a9c2d and 367d3e98; the only subsequent tracked edit was DESIGN.md grammar. A temporary capture driver was removed. LSP is unavailable (TypeScript 7.0.2 has no tsserver.js); repository typecheck passed. Browser runs used the Node PTY fallback, not the absent Rust host. Native platform checks, check full and deployment were not run. Older validation is historical.

Deterministic deadline QA (2026-10-31, historical)

The exact 1 ms boundary assertions first appeared in f8ddd887; 88628b54799e1e0022a41777d4b751dc983f5556 owns the frozen-clock harness at the reported head and is now e5b242312d3395b7eeb24a794bd1a0eb633df2f1 after fixup/autosquash. G is unchanged. I was restacked with git rebase --onto <new H> <old H>; its final head is 7fc6f695d6a114972303c2af9a7ee3d207c38a86.

Only scripts/relay-shell-browser-qa.ts changed: 8 insertions, 1 deletion. Clock-controlled pages install a fixed epoch and pause before navigation, matching the e2e harness. The offline case consumes the original pairing socket and unloads the paired app before stopping the PC, preventing its reconnect from competing with the new visit. bridge.next() and answeredRelay now select the offline visit's own socket and prove its timer is armed before explicit runFor(PC_ANSWER_MS - 1) and runFor(1) ticks. Both boundary assertions remain intact. Production channel.ts still arms PC_ANSWER_MS after assignment; its error maps through shellState.failureOf to the shell's pc-offline screen. No product change.

H's build:shell exited 0 and dist-shell/build.json names 7ca1749df291da4a117f4b02ce5b1265601ff9e5. Five consecutive standalone runs used TMPDIR=/var/tmp CHECK_DIR=/var/tmp/ck-time-<n> timeout 1800 bun run check run bun scripts/relay-shell-browser-qa.ts, each with a fresh isolated herdr session. Every report is success, exitCode 0, verified, testedSha equal to H, source unchanged, errors empty:

Run	Run ID	Duration (ms)
1	96a41aac-4f18-44f5-90b3-dca09adb5ecd	29387
2	c372f04e-a2ff-469a-bd5c-43241fbd25a1	27793
3	ffaa43e4-7d0a-4cb6-8101-45a48c9d17a8	29066
4	7806141e-0a53-45d6-94e9-b82a836b20d8	37419
5	eb85c78a-4334-4eb9-90a9-8e2c8ad23849	32744

The batch wrapper's exit-printing assignment had a quoting typo and exited 2 after all five runs. The QA exit codes above come from the five complete per-run reports, not that broken printout.

Mutation proof: temporarily change only the product timer arm to expect(PC_ANSWER_MS - 1, ...), keeping the imported constant and QA ticks unchanged. Rebuild, then run the same isolated QA in /var/tmp/ck-time-mut: exit 1 at scripts/relay-shell-browser-qa.ts:591, still connecting 1 ms before the PC's deadline, actual 0 versus expected 1. Run ID 92c3b73f-9ede-4f16-8d86-d981e1a1eb9c. The mutation was reverted with a one-line patch, git diff --exit-code passed, and the normal shell was rebuilt before e2e.

H typecheck passed. LSP is unavailable because TypeScript 7.0.2 has no tsserver.js. Native-platform checks, check full and deployment were not run.

Full relay e2e passed after the corrected bounded headroom gate: 42 GiB available and load1 46.44 immediately before launch. Command: TMPDIR=/var/tmp CHECK_DIR=/var/tmp/ck-time-e2e-gated timeout 1800 bun run check run bash -c 'FFMPEG=$(bash scripts/ci-ffmpeg.sh) timeout 1800 bun scripts/relay-e2e-regression.ts; result=$?; echo EXIT=$result; exit "$result"'. Run e39e08ca-b8dc-4183-a162-f95532d64d73 is success, exit 0, verified, source unchanged at H; output includes PASS relay media browser QA, PASS relay end to end, EXIT=0. One earlier full e2e also passed (run a1d08945-32b4-4d57-a7eb-e528051a904f), but its wrapper misquoted the headroom fields, so it is not counted as the requested gated run.

I's independent typecheck and fast checks passed on 7fc6f695d6a114972303c2af9a7ee3d207c38a86: run f52360b3-82cb-411a-a3a6-b9d6652d6b43, 10260 pass / 0 fail / 41 skip in 645 files. No push, PR or delegation. G and every protected/restored lane branch were left unchanged. All isolated sessions were torn down by their successful check-runner cleanup.

Skew fixture gate follow-up (2026-10-31, historical)

Gate follow-up DO-2/DO-3: relayShellQaVersions in scripts/relay-shell-qa-versions.ts is a pure helper used by the browser QA. It derives the old PC below min(shellVersion, MIN_SERVER_VERSION), borrowing from minor/major when patch/minor are zero, and uses that same value in the fake update status. The newer PC uses ${major}.${minor + 1}.0, so patch 999999999 remains valid. Both derived versions are asserted parseable; an unrepresentable 0.0.0 floor or exhausted minor component fails loudly rather than selecting the wrong policy branch. The helper is separate from the live QA entry point so unit imports start no browser, PC or herdr. Product policy and the 2/3/1 load-count assertions are unchanged.

The changes were fixup/autosquashed into the original PR-G skew commit (2c7d27e0, previously 76f5ca23, now f5510d72). H was restacked with --onto cafc2c285af87600b8bf90909585a68dd8b93af0 a63cef85; I with --onto 0a592cda35f7d8d5a0f16b6b2fc761be7a1dfb8e 0f7ad2e5. Only the QA script and its pure helper/test changed (48 insertions, 6 deletions versus the previous heads). PR-F's feat/relay-link was not touched; another worker owns that branch.

H: TMPDIR=/var/tmp CHECK_DIR=/var/tmp/ck-sk2-qa timeout 1800 bun run build:shell followed by isolated bun run check run bun scripts/relay-shell-browser-qa.ts exited 0 (run 8f2dfcef-e081-4c73-bdf2-5962cdfa4570, testedSha 0a592cda35f7d8d5a0f16b6b2fc761be7a1dfb8e, source unchanged). Logs show outdated PC 0.4.20 < MIN 0.4.21; newer PC 0.5.0 > shell 0.4.21 -> one reload -> app; a manual reload connects without another; same-version PC enters directly. This is H validation, not a claim that G's manual QA entry point passes.

Mutation: replaced the newer-PC reload with enterApp(opened, attempt), rebuilt the shell and ran isolated QA in /var/tmp/ck-sk2-mut. It exited 1 specifically at scripts/relay-shell-browser-qa.ts:1044: expected 2 loads, actual 1 (run 432676e1-ae60-48ee-ae46-1473c79a1f00). The product edit was reverted, git diff --exit-code passed, and the normal shell was rebuilt before e2e.

Full relay e2e ran once after a bounded foreground headroom gate (44 GiB available, load1 27.00): FFMPEG=$(bash scripts/ci-ffmpeg.sh) timeout 1800 bun scripts/relay-e2e-regression.ts, with exit preserved, inside the isolated check harness (TMPDIR=/var/tmp CHECK_DIR=/var/tmp/ck-sk2-e2e). Exit 0: PASS relay media browser QA, PASS relay end to end, EXIT=0 (run 1685da5f-3c86-4e21-ba7d-d22aacbd2280, testedSha 0a592cda35f7d8d5a0f16b6b2fc761be7a1dfb8e, source unchanged).

LSP cannot initialize (TypeScript 7.0.2 has no tsserver.js); repository typechecks passed. Native-platform checks, check full and deployment were not run. All commands ran in the foreground with timeouts, without delegation, push or PR. Earlier validation below is historical.

Initial skew fixture (2026-10-31, historical; superseded by gate follow-up)

Original owner: PR-G 2c7d27e04319ae9e017855a5dfbe22e43331f2c0 (blame and git log -L), now 76f5ca23 after fixup/autosquash. The fixture derives a PC version one patch above the shell instead of assuming MIN_SERVER_VERSION is newer. Product policy and exact load-count assertions are unchanged. H was rebased onto new G and I onto new H; H's reindent conflict retained its harness and the fixture fix. The only net source change on G, H and I is scripts/relay-shell-browser-qa.ts (10 insertions, 6 deletions).

On PR-H, bun run build:shell and isolated standalone bun scripts/relay-shell-browser-qa.ts passed (exit 0, testedSha 0f7ad2e5c4ca1d6c700e35a9182b01a47c00b546). The fixture reported server-newer: 0.4.22 > shell 0.4.21 -> one reload -> app; a manual reload connects without another; a same-version PC opened the app directly. Managed and unmanaged outdated-PC checks also passed.

Mutation proof: temporarily replaced the server-newer reload with enterApp(opened, attempt), rebuilt the shell and ran the same isolated QA. It exited 1 at scripts/relay-shell-browser-qa.ts:1047: expected 2 page loads, actual 1. The product mutation was reverted, the clean tree checked, and the normal shell rebuilt before full e2e.

Full e2e ran once after the bounded foreground headroom gate (38 GiB available, load1 58.57): pinned FFMPEG=$(bash scripts/ci-ffmpeg.sh) timeout 1800 bun scripts/relay-e2e-regression.ts inside bun run check run, with TMPDIR=/var/tmp CHECK_DIR=/var/tmp/ck-skew-e2e. Exit 0; PASS relay media browser QA, PASS relay end to end, EXIT=0. This includes terminal I/O, roster, reconnect without replay, revoke, shell states/push rotation, worker/blob isolation, remote media and MP4 seek/Range. The report verified source unchanged at 0f7ad2e5c4ca1d6c700e35a9182b01a47c00b546.

LSP cannot initialize because TypeScript 7.0.2 supplies no tsserver.js; repository typecheck passed. Browser runs used the Node PTY fallback because the Rust host binary is absent. No full repository check, native Windows/Mac/iOS/Android check or deployment was run. No push, PR, delegation or changes to protected/restored lane branches. Earlier validation below is historical and does not describe the current head.

Authoritative proof restack (2026-10-31, historical)

On the previous head cd99dfe3: bun install --frozen-lockfile made no changes; bun run typecheck exited 0; bun test --timeout 15000 server/relay src/lib/relay shared relay scripts/ci-browser.test.ts scripts/relay-skew.test.ts scripts/relay-deploy-workflow.test.ts passed once: 773 pass / 0 fail in 39 files. All commands used TMPDIR=/var/tmp, with inherited FFMPEG unset.

H's build:shell passed. The relay e2e ran once in a fresh isolated herdr session: exit 1 at scripts/relay-shell-browser-qa.ts:1043 (2 expected page loads, 1 observed). Core pairing, terminal, roster, reconnect/no-replay and revoke checks passed first. The skew fixture assumes MIN_SERVER_VERSION > shellVersion, but both are 0.4.21. One isolated rerun of the shell QA reproduced the same failure; it remains unchanged and is not called pre-existing without an untouched-main reproduction. The media QA skipped by that assertion passed separately with pinned ffmpeg and isolated herdr.

Fast checks passed at the top of the stack, I b893389625b98f56578035efe0d30f8de541a9b8, not separately on this head.

LSP could not initialize (TypeScript 7.0.2 has no tsserver.js); the repository typecheck passed. Not run in this restack: check full, native Windows/Mac/iOS/Android or live deployment. See proof-reconcile.md for conflict resolutions and the e2e finding. Older validation below is historical only.

Restack onto PR-D 5cb1417 (2026-10-31, second pass)

PR-D's merge pass added 789fc39 (merge of origin/main) and 5cb1417 (two HIGH auth fixes in server/relay/virtual-socket.ts and shared/relay-mux-engine.ts: keys not yet typed when the peer closes are dropped, and observe is applied before keys still in flight). Rebased onto PR-G ac431ccf without conflicts. Nothing in this stack changes either fix: the only stack commit touching those files (PR-G's "queue relay requests while every stream slot is busy") just adds MuxEngine.onStreamAvailable. git range-diff shows all 23 patches identical.

On HEAD 6bffc8de: bun install --frozen-lockfile no changes; bun run typecheck exit 0; bun test --timeout 15000 server/relay src/lib/relay shared relay scripts/ci-browser.test.ts scripts/relay-skew.test.ts once: 741 pass / 0 fail in 39 files; check fast ran once at the top of the stack (PR-I bfff437d). The relay e2e, ui-regression and check full were not rerun. The sections below are from earlier heads.

Restack (2026-10-31)

Rebased onto PR-G e696302a. Changed commits (git range-diff !): 08f79282 keeps main's Portal sign-in pieces (methodName import, portal VIA entry, guest-hidden device actions, SignOutRow, PortalPanel read-only for Portal visitors, issuePortalInvite, Portal files in the devices i18n part and file comments) next to the relay panel; 1ac333c2 keeps the Portal auth fields and /api/portal/invite in the demo next to the online relay demo; 861116d7 passes port: fixture.app.port to its new RelayLink test (PR-F's required port). The other 20 commits are unchanged.

On HEAD 083ff0a7: bun install --frozen-lockfile no changes; bun run typecheck exit 0; bun test --timeout 15000 server/relay src/lib/relay shared relay scripts/ci-browser.test.ts scripts/relay-skew.test.ts once: 738 pass / 0 fail in 39 files. check fast ran once at the top of the restacked stack (PR-I f334cab7). The relay e2e, ui-regression and check full were not rerun after the restack. The results below are from before it.

Summary

Summary by CodeRabbit

• New Features

  • Manage Ovis relay access from device settings, including relay status, pairing offers, and identity reset. Read-only users cannot change relay settings.
  • Pair phones through relay links on iOS and Android. Relay PCs can have saved names and appear with a “via relay” label.
  • See clearer relay connection and pairing messages, including when an offer is invalid or a connection is unavailable.

• Improvements

  • Relay connections now have default limits for connection rates and capacity.
  • Relay links are restricted to their intended PC scope.

Adds Ovis relay controls and pairing flows across settings, the hosted shell, and native apps. Adds scoped PC persistence and path validation, Bun relay admission limits, and browser and iOS regression runners.

Changes: Relay access and pairing

Layer / File(s)	Summary
Relay API and status polling src/lib/api.ts, src/lib/useRelay.ts, src/lib/transport.test.ts	Adds relay status, action, and offer API helpers. The useRelay hook polls status and shares pairing-code events.
Relay settings and pairing controls src/components/RelayPanel.*, src/components/DevicesPanel.*, src/components/SettingsDialog.tsx, src/lib/i18n/*, site/demo/transport.ts, scripts/relay-panel-regression.ts, scripts/ui-regression.ts, DESIGN.md	Adds relay controls, status and pairing offers to Devices settings. Pairing codes can synchronize with the Devices group, and device rows can show a via relay label. The demo transport models relay status, offers, and pairing codes.
Hosted-shell pairing links app/web/shell.js, app/web/connect.js, app/web/error.html, app/scripts/build-web.ts, scripts/app-shell.test.ts, changelog.d/relay-transport-parity.md	Classifies relay offers by origin, scope, and offer validity. Valid links open with their scope and optional name. The build script supports a validated alternate HTTPS shell origin.
Native relay PC scopes app/android/..., app/ios/App/App/HerdrBridgeViewController.swift, app/ios/App/App/HerdrShellPlugin.swift, app/ios/App/App/ScopePath.swift, app/ios/ScopePathCheck/main.swift, app/ios/App/App.xcodeproj/project.pbxproj, app/scripts/build-web.ts, docs/native-app.md	Native apps store PCs by origin or relay scope, retain optional names, and check path membership. Initial pages preserve valid pairing links; tests cover path cleaning and scope boundaries.
Relay regression runners and CI .github/workflows/ci.yml, scripts/ci-browser.sh, scripts/ci-browser.test.ts, scripts/ci-ffmpeg.sh, scripts/relay-browser-bridge.ts, scripts/relay-e2e-regression.ts, scripts/relay-ios-sim.sh, scripts/relay-ios-sim.test.ts, scripts/relay-media-browser-qa.ts, relay/server-proof.test.ts, changelog.d/relay-server-proof.md	Adds browser and iOS regression runners and routes browser CI through the combined relay regression runner. The CI setup builds the hosted shell and selects a pinned ffmpeg binary.

Bun relay limits

Layer / File(s)	Summary
Limit configuration and token buckets relay/bun-limits.ts, relay/bun-limits.test.ts, relay/bun.test.ts, relay/README.md, relay/load-smoke.ts, changelog.d/relay-bun-limits.md	Adds default per-address and global rate limits, in-memory token buckets, CLI and environment configuration, and tests for configuration and rate behavior.
Upgrade admission and capacity accounting relay/bun.ts, relay/bun-limits.test.ts, relay/README.md, relay/load-smoke.ts	Adds room and socket caps with reservations before upgrade and rollback after failed upgrades. Tests cover capacity and release behavior.

Merge Risk: Moderate · previous review 6f2e5

A single unauthenticated client can fill the self-hosted relay's room cap and stop new PCs from connecting through it. Add a separate budget for client-only rooms, or reserve capacity for PC connections, before relying on the default limits. The other findings are minor.

Strict review by the merge pass at 6f2e5e1 (two Claude reviewers and a Terra 6.1 pass). Server-side access control holds (origin, watch devices, Portal visitors and relay-connected requests are refused), native path scoping is segment-exact (no /pc1 vs /pc10 or traversal), link values are inserted as text, and the flood/frame limits hold. 344 relay/app/CI tests pass; mutation checks on the capacity check, upgrade release, offer server_id, exact origin and update header each fail a test.

Reproduced, to fix before merge (all three reviewers found item 1):

1. MEDIUM, relay/bun.ts:58 and relay/core.ts:284: the self-hosted Bun relay rate-limits new connections but does not cap open sockets per address, and a client waiting in a room whose PC is not online has no deadline (keepalives defeat the idle timeout). One address at the default rate fills the 256-room cap in about 3 minutes (legit PC control socket after one address held 256 client sockets: 503 relay capacity reached), or all 1024 sockets in about 9 minutes, after which every real PC gets 503. Suggested: a per-address open-socket cap and a deadline for clients waiting on a PC that is not online. (The hosted relay runs the Cloudflare worker; main had no caps at all.)
2. LOW-MEDIUM, src/components/RelayPanel.tsx:35: on = blocked === null && phase !== "off", so when a start fails before the link exists (e.g. relay/state.json cannot be written) the server answers phase:"error", requestRelay resolves it as a status, and the switch shows on while the relay is off, with nothing retrying. Repro: requestRelay(start) resolved: {"phase":"error",...} | RelayPanel on = true | linked = false. Only a link that exists and is retrying should read as on.
3. MEDIUM (Terra), scripts/relay-ios-sim.sh:251: the iOS simulator helper clones WebDriverAgent's default branch unpinned and builds and runs it on the test Mac; pin and verify a commit. It is a manual helper, not CI.

LOW: the panel keeps the last state while the server is down (no staleness shown); an offer's name (up to 64 chars, bidi allowed) labels a relay PC and can copy your own PC's name (plain text, no XSS); ci-ffmpeg.sh reuses a cached binary by version string (the first download is SHA-256 pinned); Android PCStore.setName can split a character at 64; relay-ios-sim.test.ts asserts script text. Screenshots for the owner are in ~/.dori/reports/pr-2514/.

31-34: Trivial · Performance & Scalability · Quick win

useRelay() polls /api/relay in the hosted shell, where the panel never renders.

The hooks run before the inRelayShell() early return. useRelay() therefore starts polling every 1.5–15 s while Settings is open in the shell. Every poll crosses the end-to-end relay, and the result is discarded. Pass an enabled flag so the hook skips polling in the shell.

Proposed fix

-  const { status, unsupported, pending, request } = useRelay();
+  const shell = inRelayShell();
+  const { status, unsupported, pending, request } = useRelay(!shell);
   ...
-  if (unsupported || status === null || inRelayShell()) return null;
+  if (unsupported || status === null || shell) return null;

In src/lib/useRelay.ts, change the signature to useRelay(enabled = true). Change the poll guard to if (!enabled || !visible || unsupported) return;. Add enabled to the effect dependency list.

admitted.server_id so client-only rooms cannot consume all room capacity and
block new PC connections; limit those rooms separately or reserve room capacity
for PCs while preserving the existing socket limit.

Playwright’s Response type from playwright-core instead of the global Fetch

Fixes for the merge pass's strict review at 6f2e5e1, pushed as 9f38edc, 3de5bba and a8c3f1d, plus a merge of main (183ca0d, docs only).

1. MEDIUM, relay limits (relay/bun.ts, relay/core.ts), in 9f38edc

• The Bun relay counts open sockets per address: waiting, connected and still upgrading. Past 64 (--max-sockets-per-address / RELAY_MAX_SOCKETS_PER_ADDRESS) a new socket is refused with 429 too many open connections from this address and Retry-After: 60. Sockets already open are never closed for it, so signed-in phones and PCs keep their place. The count is released exactly once, when the upgrade fails or when the socket closes.
• A client waiting while no PC is connected now closes 1013 the server is not connected after 30 s (OFFLINE_WAIT_MS), keepalives or not. The 30 s runs from the client's arrival or from the PC leaving, and it is kept with the socket across a Durable Object eviction. A PC that comes back in time replaces it with the usual 15 s handshake deadline. Answered clients never get a deadline. The app itself gives up after 15 s (PC_ANSWER_MS), so a real client loses nothing.
• Failing first: bun-limits.test.ts "one address cannot hold more than its share…" and the flags test failed before the change. In worker.test.ts, the two tests that encoded the unbounded wait now encode the 30 s deadline, and a new test covers the offline deadline across an eviction with keepalives. relay/README.md and changelog.d/relay-bun-limits.md are updated.

2. LOW-MEDIUM, relay switch (RelayPanel.tsx), in 3de5bba

• When a start fails before the link exists, the server now reports phase: "off" with the error, and the route answers 500. A link that exists and is retrying still reports error and answers 200.
• The switch reads off, and the panel shows "The relay did not start: …" with a Try again button.
• Failing first: two service.contract.test.ts cases failed before the change. In the browser, relay-panel-regression.ts now drives a start whose state.json cannot be written, then Try again after the cause is removed. It fails at the alert assertion without the panel change and passes with it.

3. MEDIUM (Terra), scripts/relay-ios-sim.sh, in a8c3f1d

• WebDriverAgent is fetched by commit 02cb92f0e93c8b021443bcbb8eeb80932c113220 (tag v16.15.3) and checked with rev-parse before it builds. I checked the fetch and the check here. An unknown commit is refused by GitHub (not our ref).

Polish

• At phone widths (640 px or less) the Tailscale command wraps and shows in full instead of being cut.
• The relay switch is the shared Settings toggle (.settings-toggle), so its off track already uses the same theme tokens (--bg-input, --border-strong) as Keep screen on. I made no relay-specific change.

Screenshots (the demo with host workstation.example.ts.net, no real tailnet name) are in ~/.dori/reports/pr-2514/settings-relay-{1280,390}-codex-{dark,light}-{off,on}.png. The earlier shots moved to previous-6f2e5e19/.

Validation

• Ran:
  • bun run check fast, green on the committed tree before the docs-only merge of main.
  • bun test ./relay server/relay: 174 pass, 0 fail.
  • The relay panel browser regression, which passes.
  • bun relay/load-smoke.ts --pcs 50 --clients 4, which passes.
• Not run: check full, Native Windows, and the iOS Simulator helper on eamac.

Review

• omo code reviewer: APPROVE. I fixed its two MINOR findings (the sweep's close reason now reads whether the PC is connected when each socket closes) and its NIT.
• Codex gpt-6.1-terra: its MAJOR finding was a duplicate "Try again" i18n key in an intermediate diff, removed before commit. I declined its MINOR finding, the server's English reason inside the translated sentence: the panel already does this for Error: {message}.

Merging 183ca0d on the owner's go (screenshots OK, 0.4.22): the Settings switch for remote access through the Ovis relay, plus the native apps' relay support. Strict review by the merge pass: two Claude reviewers and Terra 6.1 on 6f2e5e1, then a Claude and a Terra delta review of the fix round. Reproduced and fixed in 183ca0d: one address could fill the self-hosted Bun relay's room cap (now 64 open sockets per address, 429 without evicting, and a 30 s deadline for clients waiting on a PC that is not connected); a failed start showed the switch on (now off with the reason and Try again); WebDriverAgent cloned unpinned (now commit 02cb92f0, verified; a wrong commit fails closed). Checked on real Bun: close never comes before open for an upgraded socket (200 aborts before and after the 101), so no room reservation leaks. bun test relay/ 326/0 and the new tests fail with the fixes reverted. Server-side access control holds: watch devices, Portal visitors and relay-connected requests cannot start, stop or reset the relay. LOW, for a follow-up: the deadline set when a PC leaves (pauseWaiting, relay/core.ts:387) has no regression test (reverting it alone keeps the suite green); each PC departure gives waiting clients a fresh 30 s; 64 sockets per address fits one or two busy PCs behind one NAT (documented, adjustable); two saved relay PCs with the same name are labelled alike; a typing nit in scripts/relay-panel-regression.ts; the panel keeps its last state while the server is unreachable; Android PCStore.setName can split a character at 64; ci-ffmpeg.sh reuses a cached binary by version string (first download SHA-256 pinned). The .github/workflows/ci.yml change has the owner's go.
