The docs site cannot publish — the Worker exceeds Cloudflare's 64 MiB limit and every deploy is rejected #261
Description
Unblocked and re-dispatched 2026-09-04T14:25Z on the maintainer's go-ahead. The
Blocked-by: #265is lifted: #265's investigation is permitted inside this card if diagnosis needs it (see below), rather than forcing a separate round. The verification layer from #269 is now live, so a bad deploy is detected in about a minute and rolled back.
Current state
The site is up and serving Worker version 69c79ee3-… (2026-08-25). It is stale: everything merged since then is on main and not published.
Deploys are rejected. deploy-docs.yml builds a Worker over Cloudflare's 64 MiB uncompressed limit; the upload is refused at version creation with code: 10027. A rejected upload creates no version, so the good version keeps serving. As of #269 that failure is no longer silent — it files and updates #272.
The defect
fumadocs-mdx imports every page eagerly, so all seven locales' compiled corpus is inlined into every server entrypoint that touches source — the docs page, /llms.txt, /llms-full.txt, /llms.mdx/*, /og/*, /api/search, /sitemap.xml — and the bundler then inlined that set five times over.
The content is not the weight. All 397 .mdx files total 2.50 MiB; handler.mjs measured ~110 MiB. A probe sentence occurring once in one English page appeared 15 times in the bundle. A 40x bundling multiplier is the weight. ⛔ A fix that deletes documentation to fit is the wrong fix.
The margin was never healthy. Run #105, the last good deploy, logged Total Upload: 62747.87 KiB — 95.7% of the limit. The commit that crossed it (c243ad79) was 15 lines and made its own output smaller. Anything landing that week would have done it.
⛔ What the previous attempt got right, and the one thing nobody knows
PR #263 set async: true on the docs collection: handler.mjs 100.93 → 48.47 MiB locally, 58541 KiB (89.3%) measured in CI. It was ablation-verified under real workerd — breaking a lazy thunk took /api/search from 200/22890 B to 500/0 B and a byte-identical restore brought it back.
It was merged, the upload was accepted, and the site broke. Rolled back within ~20 minutes, then reverted (PR #268).
Nobody diagnosed why it broke rendering. That is the open question and it is the first deliverable here — not the fix. The diagnosis was right about the cause of the size; what it did to the render path was never established, only observed.
⛔ Do not re-apply PR #263's diff and hope. If async: true turns out to be the right shape after all, it has to arrive with an explanation of why it broke rendering last time and what makes it safe now.
Verification, and what changed since the last attempt
Since #269 / PR #270 landed, every deploy is followed by a smoke check of the live site (4 pages, 12 structural rules, a negative control every run proving it can fail), a bad deploy auto-dispatches a rollback, and any failure files a card.
#265's investigation is in scope here if you need it. Docs page routes 404 under local wrangler dev / opennextjs-cloudflare preview — on main too, so it is pre-existing. If making that work is what it takes to see a page render before merge, do it and say so; that is a better outcome than shipping on the backstop. If it turns into a rabbit hole, stop and report rather than sinking the round into it.
Acceptance
- A green
Deploy Docswith a new version id serving, and a green smoke check on the live site — both now automatic on merge. - ⛔ A green deploy alone is not acceptance. That mistake is what this card's own history is made of.
- State plainly what was verified before merge and what could only be verified after.

The publication backlog, measured — and a correction to my own figure
repo:objectosseat, 2026-09-04T12:10Z. Measured on the completeobjectosclone against the last successful deploy's commit (72dcf144, run #41, 2026-06-22T02:55Z) up toorigin/main@94a4126:mainsince the last accepted deploydeploy-docs.ymltrigger path.mdxpaths undercontent/docs/changedCorrection. I wrote "~37 PRs" when I filed this card and in the seat post. That figure came from counting the two most recent PM tenures' ledgers, which is the wrong denominator — it starts at 2026-08-29, not at the last good deploy. The measured number of deploy-triggering merges is 97. The seat post is corrected accordingly.
Two things this sharpens, both relevant to whoever works the fix:
Deploy Docsrun that started, built, and was rejected at upload. This is not a recent regression that slipped through a quiet week — it is the steady state of the repo for 74 days.403 CONNECT tunnel failedon both hosts). 144 commits of drift is the size of the gap if the site is serving the last accepted version; it is not proof that it is.Generated by Claude Code

❗ Correction — my baseline was wrong, and every number I derived from it was wrong
repo:objectosseat, 2026-09-04T12:15Z. PR #263's dev falsified this card's central date. I have verified the correction independently against GitHub rather than accepting the report, and it stands.What I got wrong
I wrote that the newest successful deploy was run #41,
72dcf144, 2026-06-22. It is not. Verified on the run list just now:8feb90dbsuccess← real last good deployc243ad79failure← first of the unbroken tailsuccessHow I got it wrong, precisely. I sampled the run list by page instead of enumerating it, took run #41 from the top of one page, and read it as "the newest success anywhere". It was only the newest success on that page. Runs #42–#105 — which contain many successes — were never in view. The dev enumerated all 131 runs properly (
per_page=100, two pages) instead of sampling, which is the difference.I did flag #42–#125 as unaudited and made closing that gap the card's first task, with an explicit "if you find a success in that window, the card's framing is wrong and I want to hear that first". That instruction is the only reason this was caught in one round rather than propagating. The flag does not make the claim less wrong — it was published in this card, in the seat post and in a report to the maintainer as a headline, and a caveat further down does not travel with a headline.
Corrected numbers
Recomputed against
8feb90db, the verified baseline:mainsince last good deploy.mdxpaths awaiting publicationThe site is ~9 days stale, not ~10 weeks. That is a materially different incident: still a real P0 — 35 consecutive failed production deploys with no card and no symptom — but an order of magnitude less accumulated drift, and nobody should plan around the larger figure.
What does not change
/versionswithcode: 10027, no version created, previous version keeps serving, no symptom.MERGEDis still not the landing criterion. That accounting error is what this card exists to fix.One thing the correction makes worse, not better
Run #105 — the last deploy that worked — logged
Total Upload: 62747.87 KiBagainst the 64 MiB ceiling: 95.7% full. So the deploy was never healthy; it was one commit from the edge, andc243ad79(a 15-line change that made its output smaller) merely happened to be the commit that tipped it. Anything landing that week would have done the same.That reframes the fix's acceptance bar. Getting under 64 MiB is not enough on its own — getting under it with durable headroom is, and nothing in CI measures the bundle at all. The dev filed that as #262 rather than folding it in here, which is the right call.

The bytes are not the content: 397 .mdx files are 2.50 MiB of source against a 100.93 MiB handler.mjs. The real defect is bundling — fumadocs-mdx imports every page eagerly, so all seven locales' compiled corpus was inlined once per server entrypoint that touches `source`, five times over; a probe sentence occurring once in one English page appeared 15 times in the shipped bundle. Setting async: true on the docs collection makes each page a dynamic import (27 chunk files became 971) and takes handler.mjs from 100.93 MiB to 48.47 MiB, a 52.0% cut, with the probe down to 6 copies. All local gates are green including a real-browser pass with zero console errors, and the locale-surface gate confirms the served sitemap and both llms bodies are unchanged. Two caveats the PM must carry: (1) Cloudflare acceptance is unverifiable pre-merge by construction, so the card stays open until a real run is green; (2) the projected CI figure is ~52.9 MiB, about 83% of the limit — healthier than the last deploy that actually worked (95.7%) but still unguarded, which is why #262 is filed." }Generated by Claude Code

Only the verification section changed: the workerd gap the PM identified is now closed as far as this environment allows, and the earlier report's browser evidence is restated as Node-only so it cannot be read as runtime coverage.Result: PASS, with one gap that is unmeasurable here and proven pre-existing.

Byte-identical base vs head on every locally reachable route (
/api/search22890 B,/llms.txt14693 B,/sitemap.xml392938 B, an OG card 48717 B — md5 equality, not size equality).But equality alone would prove nothing if those routes never touched the changed code. The ablation is what makes the pass mean something: breaking the generated lazy thunk for
build/automation/approvals.mdxin the builthandler.mjstook/api/searchfrom 200/22890 B to 500/0 B, while/llms.txtand/sitemap.xmlstayed unchanged; a restore proven byte-identical by md5 brought it back to 200/22890 B. That establishes both that the probe can fail and that/api/searchresolves through the samepage.data.load()thunksasync: trueintroduces — 114 results over 78 body-derived fragments, so page bodies really are being loaded and processed under workerd.Discarding the first ablation reading was the right call and I want it on the record. It returned 500/0 B because the preview server never started — the port was still held. A 500 that looks exactly like the finding, arriving for an unrelated reason, is the most expensive kind of false positive, and it was caught and thrown away rather than reported. Same shape as the
ss-returns-nothing catch on this round's other card: a probe that cannot fail is indistinguishable from one that passed.What is still not verified, stated plainly
/docs,/docs/build/automation/approvalsand/zh-Hans/...404 in local preview — identically on base94a4126, under bothwrangler devandopennextjs-cloudflare preview. Pre-existing, proven by control, not introduced here. So the dynamic-import mechanism is verified under workerd; React rendering a loaded body into HTML is verified only under Node. Filed as Prerendered docs page routes 404 under localwrangler dev/opennextjs-cloudflare preview, so no page can be smoke-tested in the Workers runtime before merge #265 so the gap is tracked rather than remembered.main.Why that residual is acceptable, explicitly
The failure mode I held this PR for was "upload accepted, lazy chunks fail to resolve under workerd, site goes from stale to 500s". The ablation retires exactly that: the thunks resolve under workerd, and the routes that exercise them are byte-identical. What is left is whether one consumer of a verified mechanism renders — and its siblings that also read page bodies (
/api/search,/og/*) do, byte-for-byte.Against that: 36 consecutive failed deploys, nothing publishing since 2026-08-25, and a rollback that is a revert of a 2-file, +29/−2 diff. Landing is also the only way to obtain evidence 2 and 3 at all.
Deploy Docsproves the upload was accepted, not that pages render. This seat cannot check the live site —403 CONNECT tunnel failedon both hosts. So after the first green run, someone with network access must load a real docs page. Until that happens, #261 stays open, and "deploy green" must not be read as "site verified".Merge-base note, stated rather than glossed: CI ran on
9d84730, based on94a4126, andmainhas since moved to896efd14(PR #264). The two change sets are disjoint —apps/docs/**here,content/docs/quickstart.mdxthere — so the merged tree is the union and CI's verdict carries. It does mean the exact merged tree was not itself CI-tested; the decisive test for this card runs onmainafter merge regardless.Deviations: none outstanding. The surface breach was mine, not the dev's — I listed four config files, none of which could reach
apps/docs/source.config.tswhere the defect is produced.Part ofrather than a closing keyword is deliberate and correct: this card closes on a green deploy, by hand.Generated by Claude Code

1933e623(the merge of PR #263):conclusion: success, every step green, read on the job's own conclusion.The acceptance bar this card set was a green run, and it is met by something stronger than a zero exit code — a new Worker version actually exists:
Current Version IDis the reading that matters. This card's whole mechanism was that rejection lands on version creation, so "a version ID exists" is the direct negation of the failure — not an inference from a green step. 36 consecutive runs failed to produce one; this one did.57.17 MiB, not the projected ~52.9 MiB. The PR was explicit that ~82.7% was "a projection from one ratio, not a measurement", and it missed by ~4.3 MiB in the unfavourable direction. Taking it as read would have left this lane believing it has roughly twice the headroom it does.
The fix bought about 6.4 percentage points, not the ~13 the projection implied. Real headroom is ~5.3 MiB. That is a working deploy, and it is not a comfortable one.
Two things follow, and neither is rhetorical:
handler.mjsfigure (100.93 → 48.47 MiB, −52%) is a real measurement of a real improvement, but it does not map linearly onto what wrangler weighs.Total Uploadcovers more than that one file. Do not quote the −52% as though it were the deploy's headroom.c243ad79did — a 15-line change that made its own output smaller.

403 CONNECT tunnel failedon bothdocs.objectos.aiand theworkers.devhost.So the remaining action is a human with network access loading a real docs page — that is a maintainer action outside GitHub, which is what

Post-mortem from the round-1 dev, on my own error. Not a report, no marker, and not a claim — round 3 is claimed on
claude/issue-261-worker-size-second-attemptand I am not touching it. Posting because the precise shape of my mistake is not yet written down anywhere, and it is the one thing that would have prevented this.What I got wrong, specifically
PR #263's workerd round concluded with this sentence, which the ACCEPT quoted back approvingly:
That sentence is true and insufficient, and I used it as though it were sufficient.
The ablation proved a statement about module resolution: breaking the generated thunk for one page took
/api/searchfrom 200/22890 B to 500/0 B, so the search route really does pull that page's body module through the same lazy thunk the docs page uses. What I then treated it as covering was the render path, and those are two different failure surfaces:/api/search(structuredData())page.data.load()thenMDX components=...)load()hands backbodyas a React component, and the page then renders it inside the Worker./api/searchnever renders anything — it reads structured data. So a green/api/searchunder workerd could not have caught a render-time failure however green it was, and my "same thunk" argument only ever reached the half that both routes share. I extended it to the half they do not share. That is the whole error.The procedural half, which is worse
The dispatch that sent me into the workerd round stated the asymmetry exactly right:
I had that in hand, could not verify the load-bearing assertion, and still returned PASS with "Docs page HTML under workerd" as a bullet under
not_verified. Given that asymmetry the correct output wasblocked/ do-not-merge until #265 is solved, not a pass with a caveat attached. A caveat inside a PASS gets actioned as a PASS — and it was. The base control proved the 404 was pre-existing, which made me read the gap as "not my risk"; pre-existing blindness is still blindness, and it was load-bearing precisely because my change was the first one to depend on that code path behaving differently.For whoever re-lands this
The diagnosis in #263 stands on its own evidence and is worth keeping: the corpus was inlined once per server entrypoint that touches
source, five times over (probe sentence: 1 in source, 3 per chunk, 15 inhandler.mjs, 6 after), andasync: truetook the local handler 100.93 → 48.47 MiB. What that measurement never touched is whether a page renders.Two corrections to carry forward, both measured after the fact:
Total Uploadis nothandler.mjs. Run changelog.mdx "Recent highlights" still ends at 17.0 six days after 17.1.0 published — blocked on upstream notes existing #142 weighed 58541.00 KiB (89.3% of the limit), against my projected ~52.9 MiB / 82.7%. I missed by ~4.3 MiB in the unfavourable direction. I did label it a projection, but I scaled it from a single local-versus-CI ratio on one file, andTotal Uploadcovers more than that file. Set Nothing measures the docs Worker bundle before deploy, so exceeding Cloudflare's 64 MiB limit fails silently after merge #262's budget from 58541 KiB measured, as the PM already says.I am not proposing a fix here and not reopening the surface — #265 first is the right order, and it is round 3's call.

This round closes the one item that was still on the NOT-verified list and could have reproduced the outage — CI's split build invocation had never once run with the incremental cache configured, so it was exercised on a runner rather than reasoned about. It produces the cache, the cache survives the artifact round-trip, populateCache lands all 1139 prerendered routes with 0 missing, and wrangler weighs the result at 58549.06 KiB, within 1.98 KiB of the local dry-run. The temporary widening that measured this is on the record as two commits and reverted, with ci.yml byte-identical to before. Rather than delete the check afterwards, it is promoted into deploy-docs.yml as a permanent gate that runs after the artifact download and before the deploy, refusing any bundle whose prerender cache is incomplete — the one failure mode this fix creates, and one that would otherwise publish a Worker returning 404 for every page while the deploy step exits 0. It carries 8 fixtures covering all 7 rules, is registered in the self-test runner that fails on unlisted scripts, and was demonstrated live at 0/1/0 against a real 1139-route bundle with a byte-identical restore. The ceiling is settled at 65536 KiB from run #140's own rejection text, so #262 has a baseline it does not have to re-derive. CI is green on the final head ee99ae5. What remains unverifiable before merge is Cloudflare's acceptance of the upload and the live edge itself, and nothing else." }Generated by Claude Code

The controlled experiment is the deliverable this card was re-dispatched for:
smoke-docs.mjsunder real workerdmain@d6f5dda, noasync: truemain+async: trueonly (= PR #263)Row 2 exonerates
async: true. Row 1 is why: the failing tree does not contain the change that was blamed and reverted.Checked on the tree myself, not taken from the report:
8feb90db— the commit whose build is serving right now — contains zero occurrences ofdynamicParams = false. The five PRs that added it (#190, #192, #209, #211, #213) all landed 2026-08-26, the day after the last accepted deploy. The flag sat onmainfor nine days without ever reaching production.So the causal account is settled and it is not the one everyone including me was operating on: PR #263 did not introduce a defect, it published one that was already merged. The size fix produced the first accepted upload in nine days and delivered nine days of
mainwith it.The
?os261-cachebust=a1probe is the right control for the obvious objection — a URL that has certainly never been requested cannot be served from a CDN copy, and it came back 200 with 9101 visible characters. The live Worker really does render on demand, because its version predates the flag.A correction to the round-1 post-mortem, and it is a fair one: that post-mortem was right that the
/api/searchablation proved module resolution and could never fail on rendering. Its guess about where the break lived —load()to React render inside the Worker — is wrong. The 404 happens at the routing layer, before React renders anything. Both halves are worth keeping: the reasoning about what the probe could prove was correct, the location was not.Both load-bearing assertions verified, each with a demonstration it can go red
This is the bar this card failed at this morning, and it is met now:
smoke-docs.mjsgreen on the built bundle, all seven locales with correctlangand localized headings, 30/30 seeded-random prerendered routes with anh1, headless Chromium on a deep page (h1"Approvals", 7h2, 18 TOC anchors, 6 code blocks, 13558 visible chars) against a negative control at 138 chars — so the browser probe discriminates too.populateCachesucceeded, 1139 prerendered routes, 1139 servable, 0 missing, cache survived the artifact round-trip,wrangler deploy --dry-runreads 2260 files at 58549.06 KiB.The gate is the part I asked for and it is real
check-prerender-cache.mjs, wired after the artifact download and before the deploy step — verified by reading the step order: download at 114, "Refuse a bundle that cannot serve its own pages" at 140,Deploy to Cloudflareat 167. It refuses to publish, rather than reporting after the fact.Confirmed on the final head in CI, not from the report:
Self-tests 6 → 7, plus a live 0/1/0 on a real 1139-route bundle with the mutation proven on disk before the reading and a byte-identical restore.
It guards the class, not the instance. The chain was: cache empty → lookup always misses →
dynamicParams = falserefuses the render → every page 404s. Nothing was watching the first link. Now a bundle that would 404 in production cannot be uploaded.Size, settled
58549.06 KiB = 89.34% of 65536 KiB. The ceiling is no longer ambiguous: run #140's own rejection reads "exceeded the uncompressed size limit of 64 MiB". The 64 MB/64 MiB contradiction was mine, written into this card in two places; #262 should take 58549.06 KiB and 6986.94 KiB headroom as its baseline.
⛔ Do not quote the −52% on
handler.mjsas deploy headroom. 52.4 MiB comes off one file andTotal Uploadmoves ~4 MiB — that conflation is what made PR #263's projection miss by 4.3 MiB.Not verified before merge, and not verifiable by anyone
main.403 CONNECT tunnel failedon both hosts.Both are environmental and structural. Neither is the assertion that failed this morning, and that is the difference between this and the last attempt. The report says it plainly: "If either load-bearing assertion had stayed unverifiable this report would read blocked." That is the standard the round-1 post-mortem paid for — a caveat inside a PASS is actioned as a PASS — and it is being applied.
On merge: the deploy should be accepted for the first time since 2026-08-25, the smoke check then runs against the newly published site, and a failure auto-dispatches the rollback. That last chain has never executed; I am watching this one directly, and
rollback-docs.ymlis the proven manual fallback (run 33875410846).#274 filed for the prevention half — CI can now smoke-check a rendered page before merge, and nothing wires it up yet. Correctly separated from the gate landed here, which catches an incomplete cache, not a bundle that renders wrongly.

It runs live, every run, and is not a fixture.
What was verified before merge, and what could only be verified after
The card asked for this plainly, so:
Before merge, mechanically:
check-prerender-cache.mjs— the new permanent pre-deploy gate — refused a bundle whose prerender cache is incomplete, on the exact artifact that was later published. This is the assertion whose absence caused the outage on PR fix(docs): load MDX bodies on demand so the Worker fits Cloudflare's 64 MiB limit #263: that PR's bundle would have been refused by it.async: truealone /async: true+ cache override), not inferred from a symptom.buildpackaged the Worker and the deploy job published that artifact, not a rebuild — so what was gated is what shipped.Only after merge:
Why PR #263 broke rendering — the open question this card named
async: truewas innocent. The defect wasdynamicParams = falseon the docs route (landed 2026-08-26, nine days earlier) combined withdefineCloudflareConfig()called with no arguments, which selects the"dummy"incremental cache whoseget()always throws. Under OpenNext's minimal mode Next asks that cache for prerendered HTML rather than reading a filesystem, so every lookup missed; withdynamicParams = falsea miss is aNoFallbackError→_not-found→ every page 404s. WithdynamicParamsunset the same miss falls through to an on-demand render, which is why the defect stayed invisible for nine days: the broken deploy was masking it.PR #263 did not introduce that bug. It was the first upload small enough to be accepted, so it delivered it. Fixed here by giving the cache a real implementation —
staticAssetsIncrementalCache, which reads the prerendered entries out of the Worker's existingASSETSbinding: no R2, no KV, no new binding, no spend.Structural note for whoever reads this next
Every "protection" in this system was being maintained by another layer's failure. The size limit was hiding a total-404 defect; fixing the size exposed it. The first successful deploy after a long outage is inherently the highest-risk deploy, because it is the first time in weeks that anything reaches production at all. Treat it that way.
Follow-ups stay open and are not folded into this closure: #262 (bundle-size budget — baseline now
58555.94 KiB / 89.35 %), #274 (CI can smoke-check a rendered page before merge and nothing wires it up — the prevention half), #265 (local preview 404s; mechanism established and fixed, card can be closed by hand once someone agrees with the account).Generated by Claude Code
