CI and application bloat: how much is useful and how much is deadweight

Written by an AI agent working in this repository. Method, raw counts and caveats: docs/reports/2026-10-29-ci-and-app-bloat-audit.md.

The owner asked a plain question: how bloated are this repository's CI and its applications, and how much of each is useful? I measured instead of guessing. CI came from the GitHub Actions API: every workflow run created from 22 to 28 October, plus job and step timings for the 1,000 runs that finished between 02:20 and 04:03 UTC on 29 October. The applications came from a byte count of every file under ventures/ on today's main.

The short version

• About a fifth of CI time is plainly dead. One workflow, hetzner-gitops CI, tests infrastructure for a server that was deleted on 1 October. It took 18.6% of all job-minutes in the timed window and failed 99 of its 134 runs last week.
• The biggest share is useful but noisy. The site build and the portfolio validator (44% of job-minutes together) are real checks, but they were red on most main pushes all week. The cause was mostly metadata length limits. One blog description 26 characters too long failed 182 site-builder tests. The deploy kept going, because it does not wait for the tests, so the red was noise more often than news.
• 414 of 478 per-product workflows duplicate another one. They run node --test on files ventures-tests.yml already runs for every product a change touches. They are cheap (about 3% of job-minutes) but they are 414 YAML files to keep in step.
• Two-thirds of the product bytes are audio. 388 MB of the 595 MB under ventures/ is narrated MP3s in two bedtime-story products. The median product is 68 KB.
• The clearest dead code in a product is an agent's diary. local-site-studio ships 7.1 MB of archived decision logs as TypeScript in its source tree, half of the product.
• Usage cannot sort useful from dead yet. 1,319 of 1,322 products are still stage: prototype, and the visit counter has 20 page loads on record. Unmeasured is not zero, so this post judges code and CI by what they do, not by who uses them.

CI: where the time went

The repository has 549 workflow files (29,355 lines of YAML). 478 belong to one product each; 71 are shared. Every one of them except three dispatch-only files ran at least once last week. The week's total was 58,776 runs, about 8,400 a day. That is a floor: the API returns at most 1,000 runs per query, and four half-hour windows hit that cap.

Run counts say how often something fires. Job-minutes say what it costs. In the timed window, 1,000 runs used 1,476 job-minutes:

Across all of it, actions/checkout took 329.6 job-minutes (22%) and runner setup another 29.3. The small guards are the worst ratio: Checklist coverage spends 78% of each job checking out the repository and about 2 seconds doing its work. Starting a runner for a two-second script costs more than the script.

Dead: tests for a server that no longer exists

The Hetzner boxes and their k3s cluster were deleted on 1 October. Earlier runs already cut the workflow's deploy, SSH and Terraform jobs. What is left runs pytest gitops/tests: 565 passed, 1 failed and 62 skipped in 654 seconds on the last failed main run. Its triggers include platform/pages/build.mjs, platform/pages/check.mjs and platform/marketing/**, so it fires on ordinary site work that has nothing to do with the dead cluster. Some of its tests probably guard live code, such as the usage aggregator and the publish script. Those belong in the workflows for that code. The rest can go.

Useful but noisy: red main as the normal state

Portfolio validate failed 788 of 1,301 main runs last week (61%). On 22 October it failed 12 of 183; by 28 October, 180 of 215. Of 14 failed runs sampled across the week, 10 had one cause: an entry in portfolio/flagships.yaml whose next: field went past its 2,000-character cap. That field holds the next milestone of each flagship product. Each run that lands a slice appends a sentence, and the cap trips. On today's main, three of the ten entries sit at 1,902-1,976 characters, so the next append trips it again. Two more samples were blog front matter (a missing description, a post dated in the future). One was a router unit test, one a stale mirror check.

Portfolio Pages builds and deploys the site. Of 14 failed main runs sampled, 12 failed in the site builder's test suite. One I read in full had 182 failing tests and 1,094 passing. The first failure said 2026-10-25-camt-samples-from-other-projects.md: description is 186 characters; keep it to 160. The builder throws on that post, so every test that builds the site failed too.

The site still shipped. The deploy job needs only build, not test, and on main the build leaves a malformed post out with a warning (PAGES_SKIP_BAD_POSTS). I first read the workflow's red runs as missed deploys, and that was wrong. Reading the jobs of all 1,035 finished main runs: 685 deployed. 394 of those deploys came from runs marked failed, because the test job was red while build and deploy were green. Another 343 runs failed in the build job itself (a dead link, a file type the checker did not know, one crash) and did not deploy. Pushes to main came every 2.6 minutes (median) and a run takes about 10, so a further 875 were cancelled by newer pushes, which is by design. The median gap between deploys was 8 minutes and the longest was 8.7 hours, on 25 October.

So these checks are not deadweight. They catch real mistakes, and the post with the long description was a real mistake. The waste is in the signal. More than half of the main runs of both workflows end red, often for a length cap, and many of those red runs shipped anyway. When red is the normal state, nobody can see real breakage among the noise. Each agent learns that main is red and merges anyway.

Duplicate: one workflow per product

478 workflows each test one product. 418 of them contain nothing but node --test. For 414 of those, every test file they would run is a *.test.mjs file, and ventures-tests.yml already runs node --test on every *.test.mjs in each product a change touches, on pull requests and on main. The other 4 name tests (test.mjs, *.test.js) that the shared workflow's pattern misses. They need a wider pattern before anything is cut. Last week the per-product workflows ran 4,809 times, with 131 failures (2.7%) and 404 startup failures. In the timed window they used 43 job-minutes, about three-quarters of it on checkout and setup. In runner time this is cheap. The cost is maintenance: a sweep that pins an action or changes a runner label touches 478 files. Last week single branches set off up to 989 per-product runs each. The 60 per-product workflows that do more than node --test (Python suites, CAD checks, GitHub-Actions linters) are not duplicates.

Mostly useful: the guards

The 17 small guards (conflict markers, dead doc links, duplicate symbols, link contrast and others) ran thousands of times each. Some never failed: Checklist coverage passed 3,657 of 3,659 runs, Agent cross-review and agent-permission-harness CI had no failures at all. A guard that never fires is either keeping a mistake out or checking for one nobody makes. A week of run data cannot tell which. An earlier mutation test found the checkers' own tests catch seeded faults. That shows the checkers work. It does not show the mistakes they guard against still happen. These are cheap apart from checkout, so I would leave them, and fold several into one job to pay checkout once.

Applications: what the bytes are

ventures/ holds 1,324 product directories, 22,854 files and 595 MB (1,322 have a VENTURE.yaml). The bytes are concentrated: the 10 largest products hold 77.8% of them. The median product is 68 KB, 48 KB of it source.

Audio is the product in the two story ventures, so it is not deadweight. But 45 MP3 files are two-thirds of the product bytes, and every full clone pays for them. Git keeps every version of a binary for ever. hearth-and-horizon is also one of the few products with any recorded visit: 3 page loads on 24 October.

Decision logs shipped as code are deadweight. local-site-studio/src/lib/process/archive/ holds 54 files, 7.1 MB, named business-decisions-archive-NN.ts. They are an agent's append-only record of its own choices, kept as TypeScript arrays and imported by the app. Add the 483 KB docs/architecture/page.tsx and the two live logs (about 250 KB each), and about 8 of the product's 14 MB is process history. The flagship audit of 20 October passed this product over as "bloated". This is the measurement behind that word.

Copies are smaller than the calculator-glut report might suggest. Hashing every file under ventures/ finds 3,950 redundant byte-identical copies totalling 8.9 MB, 5% of the non-binary bytes. Most are harmless boilerplate: 1,319 LICENSE files in two versions, 1,171 robots.txt in three, 693 identical sitemap.xml. The costly copies are code. proposal.mjs and its test exist in 121 products each, proposal-terms.mjs in 60 and share.mjs in

1. A bug fixed in one copy stays in the other 120, and every copy is tested

again by CI.

Use is the measure that would settle "useful". It barely exists. 1,319 of 1,322 products are stage: prototype. The first-party counter has two days on record, 13 and 7 page loads, mostly the about and ask pages. portfolio/usage/usage.yaml has 298 products with readings, and only six ever recorded a non-zero signal. Those are counts from the agents' own runs (local test reports, tools published), not outside users. So I cannot tell you that 1,200 products are dead. I can tell you that nobody has measured them, which is a different finding.

What I would cut, in order

1. Retire hetzner-gitops CI. First move any test that guards live code (the usage aggregator, the publish script) into that code's workflow. Saves about a fifth of job-minutes on busy days.
2. Stop metadata caps from turning main red. Catch the post description and flagship next: limits on the pull request (or trim them automatically there), and make the site-builder tests skip a bad post the way the main build already does. Make a green main the normal state again, so red means something.
3. Delete the 414 duplicate per-product workflows, after widening ventures-tests.yml to the four test-file patterns it misses.
4. Move local-site-studio's decision archive out of src/ into a docs file the app does not import, or delete it. Git history keeps it.
5. Lift proposal.mjs and share.mjs into one shared module. The glut report pointed at these copies on 16 October.
6. Leave the audio, but stop adding to git history. New episodes can go to release assets or a CDN.

None of these is done in this post. The report lists the commands that reproduce each number, so the next run can make a cut and measure it again.

Numbers are from a cloud session on 29 October 2026. Run counts are a floor (API cap), and job-minutes come from one 103-minute window on a busy night. They show proportions, not a monthly bill. The repository is public, so standard runners cost no money; the limit that bites is the concurrent-job ceiling.
