fix(ci): repair the workflow that has failed every run since 2026-08-23

[sscodeai]

Why

Every CI run of this repository has failed since 2026-08-23: 7 runs, all with zero jobs created (gh run list reports 0s for each, and the runs API returns total_count: 0 for jobs).

Root cause — the job-level condition below is not valid:

if: ${{ secrets.OPENCODE_GO_API_KEY != '' }}

GitHub only exposes github, needs, vars and inputs to jobs.<job_id>.if, so the whole workflow file failed schema validation before any job could be created.

What changed (7 commits)

• test(console) — apps/console had no tests at all. 5 new tests boot the real HTTP server on an ephemeral port and exercise GET /health, GET /, an unknown route (404) and the POST /run SSE stream. No mocks.
• fix(test) — scripts/run-node-tests.mjs reported a green run for a package with zero tests ("No compiled tests found; skipping." + exit 0), which contradicts the gate semantics this project documents ("the gate FAILS if zero tests run"). It now exits 1.
• fix(ci) — make the workflow parse: gate the opt-in Pi job on the TAKUMI_PI_INTEGRATION repository variable and keep passing the secret through step env.
• chore(ci) — drop the pi-integration job. runtimes/pi is deliberately not a pnpm workspace member (it depends on the unpublished @earendil-works/pi-coding-agent SDK), so pnpm install / pnpm build never produce runtimes/pi/dist and node scripts/pi-smoke.mjs fails with ERR_MODULE_NOT_FOUND on any clean checkout. How to run it locally is documented in the workflow file.
• docs — LICENSE started with # Takumi, which broke GitHub's license detection (spdx_id: NOASSERTION — i.e. "no license") while the README badge claimed MIT; first line is now MIT License. Also added a CI status badge to both READMEs so a red build is visible from the front page.
• docs(i18n) — the Japanese SI V-model workflow shipped Chinese prompts (7 of them, in both copies of jp-si-standard/workflow.yaml) plus a Chinese requirements list in the minimal-vmodel example. Prompt language drives the language of the generated requirements/design/test artifacts, so these are now Japanese.
• chore — Chinese fragments in comments in packages/core (manager-loop.ts, acceptance-gates-core.test.ts) replaced with English.

Verification (clean checkout of this branch, Node 22.23.2 / pnpm 10.34.5)

pnpm install --frozen-lockfile   # lockfile up to date
pnpm build                       # ok
pnpm test                        # 92 tests, 89 pass, 3 skipped (no Docker daemon), 0 fail
pnpm typecheck                   # ok
act -l                           # workflow now passes schema validation
                                 #   before: "Actions YAML Schema Validation Error"

Test count went from 87 → 92 (apps/console from 0 → 5).

Notes

• push: branches: [main, dev] still lists main, which does not exist in this repository — left as is; say the word and I will drop it.
• Node 20 reaches end of life on 2026-04-30 and the matrix still tests [20, 22]; bumping to [22, 24] (plus engines/badge) is a separate follow-up.
• Actions versions (checkout@v4, setup-node@v4, pnpm/action-setup@v4) and workflow hardening (permissions, concurrency, timeout-minutes) are intentionally out of scope for this PR.
