Speeds up the in-app system update and closes some of the ways it could fail, without changing what the owner sees apart from how long it takes. Measured on two real 8 GB nano-lab boards, one on each runtime (OpenClaw and Hermes). Boards are referred to by runtime only.
What changes
Next 16: middleware → proxy.
src/middleware.ts → src/proxy.ts, from the official npx @next/codemod@canary middleware-to-proxy ., then reviewed by hand:
the function is export async function proxy;
the matcher is unchanged;
runtime: "nodejs" is removed: a proxy always runs on Node.js, and Next throws on that key.
The codemod also renamed src/tests/middleware/middleware.test.ts to a non-test file. That was reverted and done by hand: tests now live in src/tests/proxy/, and every file, import, test-duration, vitest-glob and doc reference was updated.
themeColor was removed from metadata, because the viewport export already sets it. The official metadata-to-viewport-export codemod produced a second viewport export, so this was also done by hand.
The build output now has no Next 16 deprecation warning. Before, beta printed "middleware" … deprecated and five Unsupported metadata themeColor warnings.
A box updating from an older version keeps no middleware.ts beside proxy.ts (Next refuses to build with both). Step 1's sync deletes it as a tracked file the target dropped, saves an owner's edit to it first, and clean -fd removes a stray untracked copy. Tested in install-local-edits.test.ts. Next still names the compiled proxy .next/server/middleware.js internally, and each build regenerates it.
No rebuild when there is nothing to build.step_rebuild_reboot first asks build_is_current_for_checkout. It keeps the current build only when all of these hold:
both build stamps name HEAD, with the build id beside them (verify-build-identity.sh, run as the tree's owner);
neither stamp records changed contents or untracked files;
no parked build is present;
git status is clean;
the stamp's Node version is the one the build would run on;
node-pty loads;
no .env* file Next loads is newer than the build.
Every failed condition is logged, and CLAWBOX_FORCE_REBUILD=1 always rebuilds. The restart (or reboot) that resumes the update still happens.
The second half of the update needs a changed BUILD_ID as its evidence that a rebuild happened. When the build is kept, the step writes /var/lib/clawbox/rebuild-kept-build (<BUILD_ID> <boot id> <uptime>), and checkContinuation accepts it only from the boot in which the step was dispatched and only if written after that moment. Because the note is on disk, it also survives the reboot arm.
write-build-info.mjs now also records contentDirty (with core.fileMode=false). The rebuild step makes every scripts/*.sh executable before it builds, and on a core.fileMode=true checkout that alone stamped dirty: true on every update build. This was found on the Hermes board.
The gateway is started once, by gateway_verify. On 8 GB boxes the gateway is paused for next build.
Before: the rebuild started it again while the dashboard was still down, post_update waited ~40 s for that start to finish only to stop it, and gateway_verify started it a third time.
Now, on the restart arm (outside test mode), do_rebuild --gateway-to-update leaves it stopped for the second half. Every other paused engine is still resumed.
Fallback: a transient clawbox-gateway-handback.timer (--on-boot=<now+900>s, RemainAfterElapse=no) starts the gateway only if it is still inactive with the exact InactiveEnterTimestampMonotonic the pause left. While a root update step, the updater's quiesce guard, or any OpenClaw process is running, it waits and checks again instead of starting it.
Every rebuild step cancels a fallback left by an earlier update.
--on-boot and not --on-active: on systemd 249, every daemon-reload restarts an --on-active countdown (measured on a board), so the update's own reloads kept pushing it out.
A stalled git fetch is retried instead of waited on. Under 1 KB/s for CLAWBOX_GIT_LOW_SPEED_TIME (60 s), in both install.sh and force-update.sh, and "Operation too slow" counts as a retryable failure.
The room-for-two-builds check counts .next/cache once.carry_build_cache moves the cache rather than copying it, so a box that has room for two builds keeps its old build.
Measured and deliberately left alone
bun install with an unchanged lockfile takes 0–1 s, so there is no skip for it.
postbuild takes 1–2 s.
The Turbopack build cache (turbopackFileSystemCacheForBuild, on by default since Next 16.3) is already carried into each new build, and git clean -fd leaves it alone. A warm incremental build takes 14–26 s.
OOM: next build runs in the clawbox login session's own scope (user-1000.slice/session-*.scope), not in the root step's cgroup. An OOM kill therefore takes only the build, and do_rebuild's restore still runs. The lowest MemAvailable seen while next build ran was 1075–1384 MB on the 8 GB boards.
Timing (seconds; real in-app updates through update/run)
Before = beta's code: a temporary branch identical to beta, so the on-box type check runs the same way it does for this branch. After = this branch. Both rows on a board start from the same main build.

Hermes, update from main with the same pins: 270 → 270. Hermes runs no OpenClaw gateway to hand over, and its build is unchanged.
¹ With the change, gateway_verify makes the only gateway start after the build, so that start is cold (the build drops the page cache). The time moves out of the dashboard-down window.
² Only the ~3 s clawbox-setup restart remains, and the status poll runs every 5 s.
³ 20 s of it is post_update waiting for the gateway started by the update run 30 s earlier: back-to-back test runs.
Board tests (final head, both runtimes)
(a) main → branch:
OpenClaw: 338 s; gateway settled, a real chat turn answered, runtime kept, build identity OK.
Hermes: 270 s; with the new beta's pins, 442 s including the Hermes 0.22.5 → 0.23.1 upgrade; Hermes settled, chat turn answered, OpenClaw gateway stays inactive.
(b) beta → branch: from the current beta (OpenClaw 2026.11.3 / Hermes 0.23.1): OpenClaw 559 s and Hermes 225 s, both completed and healthy.
(c) repeat with no changes: both boards log "No rebuild needed …" and the continuation logs "The rebuild step kept build …". The update completes and the box is healthy (both runtimes, on every head since the fixes the board runs found, the final head included).
(d) failed build: every next build of an update was SIGKILLed mid-run. The update ended failed, the box kept serving its previous build, /login answered 200, the runtime settled, and a chat turn was answered (both runtimes).
(e) proxy: 27 gate probes per board are identical before (beta's middleware) and after (proxy). They cover:
unauthenticated pages → 307 /login;
API → 401;
a foreign Host → 403 host_not_allowed;
the mDNS host → 200;
static, manifest and captive-portal paths;
owner cookie → 200;
a real /login-api password login of a temporary staff user (wrong password → 401, then the right one → cookie, desktop 200, owner-only API 403), the user deleted afterwards.
(f) the timing tables above.
Fallback timer on the OpenClaw board: armed on the boot clock, its deadline survived the next update's daemon-reloads, it fired once, exited because the gateway was already active, and unloaded. The waiting while a root step, the quiesce guard or a stand-in gateway is present was proven with real systemd 249 transient units.
Follow-ups (not done here)
219 Turbopack "Node.js API … Edge Runtime" warnings from the Edge compile of src/instrumentation.ts. These were already present and are not deprecations; fixing them means restructuring instrumentation's imports.
An interrupted postbuild: production-server.js reclaims the parked build only when the new build has no standalone entry. A kill between Next writing server.js and postbuild copying static//public/ serves an incomplete build. A missing standalone stamp could count as incomplete.
When the disk cannot hold two builds, the old build is still deleted before building (no app if that build then fails). Refusing the build instead would change behaviour, so that is left for a decision.
The dashboard stays stopped for the whole rebuild (for memory). Keeping it up would need measurements of the build's peak memory beside it.
post_update's bootstrap fetches and runs reset --hard a third time, so a commit pushed mid-update moves the checkout past the build (already the case before).
bun install has no explicit timeout of its own.
The build-current check does not compare variables exported in the account's login files (only .env*) or the bun version. A nested standalone layout always rebuilds.
CodeRabbit's re-review of the commits after its first review was rate-limited. Its three findings are fixed and answered in their threads, and an independent review's findings were fixed as well.

The pull request renames the Next.js request handler to the proxy convention and updates its tests and references. It also changes installer rebuild decisions, retained-build validation, gateway handoff, Git retry handling, and build-space checks. The layout removes themeColor from metadata.
Changes: Request proxy migration
Layer / File(s)
Summary
Proxy entry point and test migration src/proxy.ts, src/tests/proxy/*, src/tests/routes/hermes/oauth-wizard-handoff.test.ts, src/tests/unit/*, src/tests/helpers/test-durations.json, vitest.config.ts, scripts/pr-review.mjs
The handler export and test imports change from middleware to proxy. Existing test cases retain their expected behavior. Vitest includes the proxy test directory.
Comments and documentation identify src/proxy.ts as the request gate. The setup API guide describes the Next.js 16 proxy convention and its Node.js runtime. Other references point to the renamed test and implementation paths.
Build information now includes a content-only dirty status. The installer checks build identity, stamps, checkout cleanliness, and environment-file freshness before skipping a rebuild. The tests cover skip and refusal conditions.
The installer records a retained build ID and boot-relative uptime. The updater checks the note and dispatch timestamp before accepting an unchanged build ID as intentional.
Gateway handoff during rebuild install.sh, src/tests/unit/install-rebuild-build-verify.test.ts, src/tests/unit/install-update-reboot-decision.test.ts, src/tests/unit/install-free-memory-before-build.test.ts
Non-reboot update rebuilds can hand the paused gateway to the update continuation. A timed fallback starts the gateway under the documented conditions. Tests cover handoff and fallback behavior.
Git retry and build-space checks install.sh, scripts/force-update.sh, src/tests/unit/install-update-faster.test.ts, docs/agents/update-and-install.md
Git fetches set low-speed limits and retry matching stall errors. The build-space calculation can exclude a valid .next/cache size while leaving the cache in the parked build.
Next.js metadata update
Layer / File(s)
Summary
Theme color metadata src/app/layout.tsx, src/app/globals.css
The layout removes themeColor from metadata and comments that it belongs in viewport. A CSS comment updates the described count.
An update that keeps the current build and also needs a reboot can fail to continue after the restart, skipping the remaining update steps. The gateway can also stay stopped if its fallback timer fires during a long update step. Fix both before merging. The force-update fetch timeout is a minor follow-up.
Security architecture risk: Moderate · up to 7d476
An update can keep its current build and still reboot, but that reboot erases the evidence required to resume. The remaining system fixups and service checks can consequently be skipped, leaving the update incomplete.
Retained concerns
Medium · reliability · inferred: Intentional reboot breaks the retained-build continuation contract. The installer can skip rebuilding and then reboot, but the only proof allowing an unchanged BUILD_ID is stored under /run and disappears at boot. The resumed updater treats this successful retention as a failed rebuild, clears continuation state, and skips post_update, edition provisioning where applicable, and gateway verification. The base rebuilt before reboot and did not require this volatile exception.
Security review details
Security Blast Radius
inferred — The identified transition failure affects the updating appliance’s own post-restart fixups, applicable edition provisioning, and gateway health verification. It can occur during an ordinary update without attacker-controlled input.
Trust Boundaries and Controls
observed — The MCP bearer admission branch and loopback proxy exemptions predate this PR and are unchanged by the proxy migration. The comparison does not establish a newly introduced authorization bypass; downstream bearer implementations were not exhaustively reassessed.
observed — The retained-build note is parsed as data, not executed. Missing or malformed evidence, mismatched build identity, invalid dispatch time, or a failed rebuild unit prevents the unchanged-build exception.
Resilience and Maintainability Implications
observed — Continuation checks are single-flight within the process. Resume captures the new dispatch value before clearing it with the continuation flag, and takeover failure also clears both values. These safeguards address repetition and stale same-boot evidence but do not preserve successful retention across reboot.
Hardening Proposals
proposed — Make retention and reboot use a compatible completion contract: either rebuild whenever a reboot will follow, including a late reboot decision, or use durable, run-bound retention evidence that survives intentional reboot without admitting stale completion records.

Explanation
The title names two of the PR's main changes: the TASK-2517 faster, steadier in-app update work, and the Next 16 middleware-to-proxy rename. The changeset matches both. The title is a single line and omits the disk-check, git-retry, and gateway-handoff details, which the title does not need to cover.
Full details: Description check
Explanation
The description follows the template's main structure and contains substantive content. It has a Summary that explains the change and its reasons, detailed sections on the middleware-to-proxy rename, the update-skip logic, gateway handoff, git retry, and the disk-space check, plus measured timing tables and board test results. It also lists follow-ups. The template's required sections are only partly filled. The 'Type of change' checkboxes are not ticked, and no issue is linked. The 'Harness native mechanism' section is missing. The 'Pinned harness versions changed?' question is not answered. The 'How was this tested?' checklist is not ticked. The checklist items are not ticked either. The author's own text says board evidence and the final timing table are still in progress. These gaps are non-critical sections, so the description is mostly complete.
Full details: Persistent Tunnel Security
Explanation
Summary: The PR does not appear to change persistent Cloudflare tunnel provisioning, tunnel startup, public-hostname handling, or remote-access authentication. The check passes, with one caveat about the diff (see below). Evidence gathered - The checkout is shallow and contains only commit 7e810d5. The base commit is not present, so git diff against origin/main or HEAD~1 failed. I could not reconstruct the full PR patch. The verdict therefore relies on the per-file change summaries and the PR description, which are consistent with each other. - The PR description covers the Next 16 middleware→proxy rename, the rebuild-skip logic, gateway handback, Git low-speed retries, .next/cache disk accounting, and write-build-info.mjs. It does not mention tunnel provisioning, cloudflared, tunnel tokens, or hostnames. - The per-file summaries list no tunnel changes. The closest item is src/proxy.ts (+9/-8). Its summary lists only a function rename (middleware→proxy), removal of runtime: "nodejs", comment updates, and a log-prefix change. The matcher is unchanged. - The current src/proxy.ts contains tunnel-admission logic at lines 631–643. It uses isTunnelRequest and CF-Connecting-IP, and the summaries do not report any change to that logic. - The install.sh changes cover git_with_retry, build_is_current_for_checkout, record_rebuild_kept_build, and the gateway handback timer. The current tree shows these functions do not reference cloudflared or the tunnel. Existing tunnel references (lines 11238–11295, 12300–12315) concern opt-in service handling and the cloudflared install step. The summaries do not report changes there. - The posted CodeRabbit threads concern the gateway fallback timer, the reboot-kept-build note, and the force-update.sh low-speed timeout. None concerns tunnel criteria. Caveat: Because the PR patch could not be reconstructed, this PASS rests on the summaries and description rather than the diff. If the full diff shows a change to tunnel startup, tunnel credentials, hostname validation, or isTunnelRequest / CF-Connecting-IP handling, this verdict would need to be revisited.

- Next 16: src/middleware.ts -> src/proxy.ts (official middleware-to-proxy
codemod, reviewed by hand): `export async function proxy`, same matcher, no
`runtime` key (a proxy is always Node.js). Tests move to src/tests/proxy/,
every file/import reference follows. Build no longer warns about the
deprecated "middleware" convention. themeColor leaves `metadata` (the
viewport export already carries it), ending the other Next 16 warning.
- step_rebuild_reboot skips bun install + next build when the build on disk is
already this checkout's (build_is_current_for_checkout: both stamps name
HEAD, clean tree, same Node, no env file newer than the build, nothing
parked). The restart that resumes the update still happens.
- On the update's restart arm, a gateway paused for `next build` is handed to
the update's second half (post_update stops it first, gateway_verify starts
it) instead of being started, waited for and stopped again. A transient
timer starts it if nothing has touched it since the pause.
- git_with_retry / force-update fetch end a stalled transfer (under 1000 B/s
for 60 s) and retry it, instead of hanging until the step budget.

…-line gateway fallback
- A kept build leaves BUILD_ID unchanged, which the continuation read as "ClawBox
restarted without producing a new build" (seen on a board). The rebuild step
now notes the build it kept on /run ("<BUILD_ID> <seconds since boot>",
record_rebuild_kept_build), and the continuation accepts the unchanged id only
with that note, written after this run dispatched the step (both on the boot's
monotonic count, gone after a boot). A note that cannot be written means a
rebuild as before.
- The gateway fallback timer's script is one line: systemd writes a transient
unit's command into a unit file, and a newline split its ExecStart=.

…k; document the update changes
set_previous_build_aside deletes the serving build instead of parking it when
the disk cannot hold two builds, the one arm in which a failed build leaves no
app. It counted .next/cache (the Turbopack cache) in the build's size although
carry_build_cache moves it, so a box with room for two builds could still lose
its old one. The size is now taken without the cache.
docs/agents/update-and-install.md: what the update now skips and hands over,
with the board measurements behind each change and what was measured and
deliberately left alone.

The serving entry is a link the tree may point anywhere; root reads nothing
through it that the account could not read itself.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The update's rebuild step makes every scripts/*.sh executable before it builds,
and on a checkout with core.fileMode=true that alone stamped `dirty: true` on
every update build, so build_is_current_for_checkout never kept one there (seen
on a board). write-build-info.mjs now also records `contentDirty` (the same
probe with core.fileMode=false), and the check reads it when present; `dirty`
keeps its meaning.

…it fires
systemd 249 counts a transient timer's OnActiveSec= again from every
daemon-reload (measured on a board): the update's own reloads kept pushing the
deadline out, so it never fired. --on-boot=<now + 900>s is the same after a
reload and needs no wall clock; RemainAfterElapse=no unloads it after it fires.

…eway net waits out root steps
- The kept-build note moves from /run to /var/lib/clawbox and carries the boot
id: the reboot arm ends the rebuild step with a reboot, the second half then
resumes in the next boot, and a /run note would be gone — the kept build read
as a rebuild that never happened. The updater records { boot, uptime } at the
dispatch and accepts a note only from that boot and after that moment.
- The gateway fallback no longer ends when its deadline falls inside a root
update step: it never starts the gateway under one, looks again every 60 s
(CLAWBOX_GATEWAY_HANDBACK_RECHECK_S), and still acts only on a gateway nobody
has touched since the build's pause. Every rebuild stops its service too.
- force-update.sh honours CLAWBOX_GIT_LOW_SPEED_TIME, as install.sh does.

…Claw work; cancelled on every rebuild step
- A `systemctl stop` of a gateway that is already stopped moves no stamp, so a
doctor --fix or an offline auth edit the web server runs beside the paused
gateway was invisible to the net. It now also waits while the updater's
quiesce guard (/run/clawbox-gateway-maintenance) is up and while any OpenClaw
process runs (with the gateway down, that is someone working on it).
- A kept build never reaches do_rebuild, so step_rebuild_reboot itself now
cancels an earlier update's net.
- The x64 owner path clears the dispatch record with the continuation flag.

do_rebuild also repairs a node-pty that no longer loads (ensure_node_pty), so a
box whose terminal module is broken takes the full rebuild, as every update
did. Documents what the check does not compare.

TASK-2517: faster, steadier in-app update
Speeds up the in-app system update and closes some of the ways it could fail, without changing what the owner sees apart from how long it takes. Measured on two real 8 GB nano-lab boards, one on each runtime (OpenClaw and Hermes). Boards are referred to by runtime only.
What changes
Next 16:

The officialmetadata-to-viewport-exportcodemod produced a secondviewportexport, so this was also done by hand."middleware" … deprecatedand fiveUnsupported metadata themeColorwarnings.middleware.tsbesideproxy.ts(Next refuses to build with both). Step 1's sync deletes it as a tracked file the target dropped, saves an owner's edit to it first, andclean -fdremoves a stray untracked copy. Tested ininstall-local-edits.test.ts. Next still names the compiled proxy.next/server/middleware.jsinternally, and each build regenerates it.No rebuild when there is nothing to build.
