#1560 landed test:agent-delegation, test:agent-tasks, test:artifact-banking and test:background-commands. All four have package.json scripts. None was named by any workflow, so 93 assertions executed nowhere — the condition ci.yml already describes in its own words, "A suite wired into nothing is documentation, not a test", recurring within hours of the last round of it being fixed.

The MCP tax doesn't just make suites slow — it makes one of them fail

Measured credential-free under a socket-layer preload, mkdtemp HOME, empty CLOUDSDK_CONFIG, .env suppressed:

suite time result 60s MCP timeouts
agent-delegation 356s 18 passed / 1 FAILED 11
agent-tasks 68s 23 passed 1
artifact-banking 68s 16 passed 1
background-commands 13s 35 passed 0

The delegation failure reads as a real defect — "a finished worker must show as ready without being collected" — and is not one. That case asserts on task-lifecycle timing, and eleven sixty-second stalls moved the worker's state transition outside the window it checks.

With NEUROLINK_SKIP_MCP set: 41s, 19/19.

C3 characterised this tax as making a suite slow enough to be killed by an outer bound. It also makes timing-sensitive suites report false failures — the more expensive half, because a slow suite gets investigated and a failing one gets blamed on the code under test.

What changed

The three that build NeuroLink instances now set NEUROLINK_SKIP_MCP, as test:proxy and test:multimodal:sdk already do.

background-commands doesn't need it — it never triggered the load — and it's the only one of the four reaching no external host at all, so it's the only one that gets offline: true. The other three still contact aiplatform/oauth2.googleapis.com (and api.openai.com for delegation), where a timeout can legitimately be an upstream rather than a hang, so they're deliberately left unflagged — the same distinction applied to auth, dynamic, credentials and provider-descriptors.

Verification

All four green through their package.json scripts with zero MCP timeouts · assignment loop places all 32 suites, 0 duplicates · offline-flag placement checked by walking to defineSuite's matching paren · eslint 0 errors · check:tools-tests clean · prettier clean.

Weights are 1.9× local timings (the test:tts:unit ratio) — estimates, to be replaced from the first real run via the log-timestamp method above the list.

Merge order

Fourth PR touching the SUITES block, after #1568, #1571 and #1574. Each later one is a small rebase in that list.

📝 Walkthrough

Walkthrough

The CI workflow now treats security-suites as required and registers ten additional extended suites. Four related test suites skip MCP initialization or use offline mode to avoid startup delays.

Merge Risk: 🔵 Low · up to e6263

This changes CI to run four previously unwired suites and avoids MCP-induced stalls and false timing failures without changing product runtime behavior. The workflow still contains wording that describes 28 suites while 32 run, which may mislead future CI maintenance; merge is reasonable with explicit owner awareness or a follow-up documentation fix.

… failing one

and test:background-commands. All four have package.json scripts. None was
named by any workflow, so 93 assertions executed nowhere — the same
condition ci.yml already describes in its own words, "A suite wired into
nothing is documentation, not a test", recurring within hours of the last
round of it being fixed.

Measured credential-free under a preload hooking net.Socket.prototype.connect
and tls.connect, mkdtemp HOME, empty CLOUDSDK_CONFIG, DOTENV_CONFIG_PATH set
to /dev/null. Three of them paid the MCP client timeout that the repo's
tracked .mcp-config.json imposes on any suite building NeuroLink instances,
and on one of them that was not merely slow:

  agent-delegation   356s, 18 passed / 1 FAILED, eleven 60s MCP timeouts
  agent-tasks         68s, 23 passed, one
  artifact-banking    68s, 16 passed, one
  background-commands 13s, 35 passed, none

The delegation failure read as a real defect — "a finished worker must show
as ready without being collected" — and is not one. That case asserts on
task-lifecycle timing, and eleven sixty-second stalls moved the worker's
state transition outside the window it checks. With NEUROLINK_SKIP_MCP set
the same suite is 41s and 19/19.

That is worth stating plainly, because C3 characterised this tax as making a
suite slow enough to be killed by an outer bound. It also makes
timing-sensitive suites report false failures, which is the more expensive
half: a slow suite gets investigated, a failing one gets blamed on the code
under test.

So the three that build instances now set NEUROLINK_SKIP_MCP, as test:proxy
and test:multimodal:sdk already do. background-commands does not need it —
it never triggered the load — and it is the only one of the four that
reaches no external host at all, so it is also the only one that gets
offline: true. The other three still contact aiplatform/oauth2.googleapis.com
(and api.openai.com, for delegation), where a timeout can legitimately be an
upstream rather than a hang, so they are deliberately left unflagged — the
same distinction applied to auth, dynamic, credentials and
provider-descriptors when that flag was rolled out.

Weights are 1.9x the local timings, the ratio measured for test:tts:unit,
and are estimates to be replaced from the first real run via the
log-timestamp method documented above the list.

Verified: all four green through their package.json scripts with zero MCP
timeouts, the workflow's own assignment loop places all 32 suites with no
duplicates, offline-flag placement checked by walking to defineSuite's
matching paren, eslint 0 errors, check:tools-tests clean, prettier clean.

Your semantic-release bot 📦🚀

murdore added a commit that referenced this pull request Oct 3, 2026
Closes the review threads left open on merged PRs against the CI workflows,
the repo's gate scripts and a few dev tools. Each change is the smallest one
that closes its finding. Behaviour changes are covered by a new suite
(test/continuous-test-suite-tooling-scripts.ts, `pnpm run test:tooling-scripts`)
and by additions to the provider-structure and provider-descriptors suites;
every new test was run red against the unfixed source first.

Workflows
- ci.yml: persist-credentials: false on the seven checkouts that never push,
  semantic-release-validation keeps its token (T3790294038, #1335). The
  permissions comment names that job as the one contents: write exception
  (T3858986829-a, #1552). The pinned suite counts and the 373-assertion figure
  are gone (T3869180755-f1, #1580). The new tooling-scripts suite is added to
  extended-suites; its weight (100) is an estimate, not a CI median.
- release.yml: the ffmpeg note no longer says build-check gates this workflow
  (T3810295618-a, #1360).
- single-commit-enforcement.yml: one SKIP_RE shared by both greps, printf
  instead of echo, and the guidance names the push/pull_request workflows
  rather than "every workflow" (T3813387872-printf-regex,
  T3813416696-overstated-guidance, #1364).

Config and lint docs
- config/models.json: Opus 4.5 uses the real snapshot id 20251101 for
  anthropic, bedrock and vertex instead of the 20251124 launch date
  (T3816077440, #1375). provider-structure now checks every Claude id in the
  file against the model enums.
- eslint-rules/index.cjs: header lists e2e-tests-only, no-inline-secret-regex,
  provider-typed-errors and provider-base-class (T3801758166-1, #1344).

Scripts
- build-validations.ts: fails when typedoc.json carries an unanchored
  `**/<dir>/**` exclude, which drops every file under a checkout whose path
  contains that directory (T4042344752-guard, #1723).
- check-banned-deps.ts: scans each file as a whole, so import(), require() and
  `from` followed by a specifier on the next line are found, and a `//` inside
  a string no longer hides the rest of the line (T3956062753, #1662). Files in
  the repo root and .mts/.cts are scanned too (T3956062775, #1662).
- check-shipped-types.ts: the declarations under dist/ must equal the set the
  source tree emits, so a partial or stale build above the 100-file floor
  fails (PF-T3927528338, #1627). A wildcard export is matched against the whole
  pattern, including a `*` in a directory component (T3931686738-wildcard-match,
  #1632).
- codex-replay-listener.ts: the tool-call script names `replay_tool` instead of
  `exec`, which Codex declares as a custom tool and which raised a Fatal
  "incompatible payload" error (F1-T4087477953-custom-tool-shape, #1783);
  reproduced and cleared against codex-cli 0.160.0. --requests counts served
  /responses turns, so a 404 probe cannot shut the listener down first
  (F2-T4087477985-requests-limit-counts-404s, #1783).
- commit-validation.ts: execFileSync("git", [...]) instead of a shell string;
  behaviour unchanged (T3838161513-b, #1499).
- migration-symbol-diff.mjs: this/super-rooted paths keep their full name, and
  tagged templates, obj["name"](), super() and import() are tracked; the
  header says it follows calls (T3835058026-residual, PF-T3833252257, #1448).
- tools/automation/environmentManager.ts: credential-free providers count as
  configured only when the .env sets one of their variables, the score no
  longer divides by the size of the catalog, and the report lists the
  configured providers plus one count instead of every missing one
  (T3792794348, T3792807279, #1337).

Not done, on purpose
- The skip-checks trailer in the single-commit grep (optional in the finding).
- Checkouts in workflows other than ci.yml: the findings named only ci.yml.
- migration-symbol-diff still does not record a function passed by reference
  (`items.forEach(handler)`); the header now says so.

Pre-existing, not touched: test:dynamic fails its five live cases without
provider credentials, identically with config/models.json reverted.
