The docs site cannot publish — the Worker exceeds Cloudflare's 64 MiB limit and every deploy is rejected

[os-project-manager]

Unblocked and re-dispatched 2026-09-04T14:25Z on the maintainer's go-ahead. The Blocked-by: #265 is 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.

⚠️ That net is a backstop, not the verification. The chain deploy succeeds → smoke fails → rollback fires has never executed, because no deploy has succeeded since the layer landed. Relying on it as the primary check would be this morning's mistake wearing better clothes.

#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 Docs with 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.

Re-check

# what is serving, and the size of the last accepted upload
gh workflow run rollback-docs.yml          # blank version_id = list only, changes nothing
gh run list --workflow=ci.yml --branch=main --limit=5

# the multiplier, on the current tree
git show origin/main:apps/docs/source.config.ts

⚠️ Note on identity, for whoever reads this next: a dev subagent dispatched from this loop shares this session ID. A second Claim: here carrying session_01GkauAsZBEemRbco2rEX9Lx is not a competing claimant — the branch name is the discriminator.

assignee: untouched — it is the PM's field and is already set.

Working the premise-first order from the card: (1) close the #42–#125 audit gap and establish the real first-failing run, (2) measure the actual byte composition of the 110 MiB handler, (3) only then fix.

The publication backlog, measured — and a correction to my own figure

repo:objectos seat, 2026-09-04T12:10Z. Measured on the complete objectos clone against the last successful deploy's commit (72dcf144, run #41, 2026-06-22T02:55Z) up to origin/main @ 94a4126:

$ git rev-list --count 72dcf144..origin/main
144
$ git rev-list 72dcf144..origin/main -- content/docs apps/docs | wc -l
97
$ git diff --name-only 72dcf144 origin/main -- 'content/docs/*' | wc -l
545

Reading	Value
Commits on main since the last accepted deploy	144
…of those, touching a deploy-docs.yml trigger path	97
Distinct .mdx paths under content/docs/ changed	545 (locale siblings included)
Days since the last accepted deploy	74

Correction. 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:

1. 97 failed deploys, not a handful. Each one is a separate Deploy Docs run 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.
2. The first accepted deploy after the fix publishes all 545 changed paths at once. That is the correct outcome and nothing about it should be throttled — every one of those changes is reviewed and merged. But it is worth stating in the PR body, because the person merging the fix should know the blast radius is "74 days of accumulated docs go live", not "a config tweak lands".

⚠️ Neither reading tells you what the site currently serves — that is still the unmeasured probe this container cannot take (403 CONNECT tunnel failed on 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.

❗ Correction — my baseline was wrong, and every number I derived from it was wrong

repo:objectos seat, 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:

Run	Commit	Time	Conclusion
#105	8feb90db	2026-08-25T15:36:25Z	success ← real last good deploy
#106	c243ad79	2026-08-25T21:05:44Z	failure ← first of the unbroken tail
#107–#110		2026-08-25 → 08-26	failure
#96–#105		2026-08-22 → 08-25	all success

How 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:

Reading	Published (wrong)	Corrected
Days dark	74	9
Commits on main since last good deploy	144	43
Deploy-triggering merges (all failed)	97	35
Changed .mdx paths awaiting publication	545	88

The 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

• The mechanism is exactly as filed: Worker over the 64 MiB ceiling, rejected at /versions with code: 10027, no version created, previous version keeps serving, no symptom.
• The structural lesson is unchanged and is arguably sharper: a post-merge workflow appears on no PR's check list, so 35 red deploys ran across two PM tenures with no card.
• MERGED is 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 KiB against the 64 MiB ceiling: 95.7% full. So the deploy was never healthy; it was one commit from the edge, and c243ad79 (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."
