ci(workflows): add reusable CI foundation

[scttbnsn]

Summary

• add SHA-pinnable reusable Go and Node CI workflows with typed topology inputs, fixed repository-owned scripts, per-job egress controls, and centralized artifact handling
• add an exact-SHA release gate that checks every requested workflow for a successful push run with a nonempty source branch
• register executable source and behavior contracts in Standards Validation

TDD evidence

• RED: the expanded contract failed all six topology/release assertions against the original lint/test-only implementation
• RED: actionlint rejected the unquoted fuzzers-json string default, and the tightened contract reproduced it
• RED: review contracts reproduced raw JSON fuzz gating, per-workflow sleep budgets, and API-host/egress mismatch as three failures
• GREEN: 11/11 reusable CI contract tests pass, including fake-API multi-workflow polling, in-progress retry, exact-SHA, event, and branch behavior

Verification

• 12/12 community health contract tests
• 1/1 Greptile config contract test
• 11/11 reusable CI contract tests
• Python compile, YAML/JSON parse, and diff checks
• markdownlint-cli2 0.23.2
• actionlint 1.7.12
• zizmor 1.29.0 offline, no findings
• normal git push without hook bypass

Summary by CodeRabbit

• New Features

  • Added reusable Go and Node.js CI workflows with configurable versions, checks, caching, security gates, testing, linting, builds, fuzzing, and artifact uploads.
  • Added a reusable release-gate workflow that validates required workflows and monitors target-commit runs.
  • Added configurable runner egress policies and least-privilege permissions.

• Tests

  • Added comprehensive validation for CI workflow contracts and release-gate behavior.
  • Integrated these checks into standards validation.

📝 Walkthrough

Walkthrough

This PR adds reusable Go, Node, and release-gate workflows. It defines typed inputs, hardened CI jobs, artifact handling, release-run polling, Python contract tests, and standards-validation wiring.

Changes

Reusable CI and release validation

Layer / File(s)	Summary
Workflow interfaces and CI jobs .github/workflows/go-ci.yml, .github/workflows/node-ci.yml	Adds typed inputs, conditional Go and Node jobs, pinned actions, hardened runners, egress controls, repository scripts, and artifact uploads.
Release-gate validation and polling .github/workflows/release-gate.yml	Validates inputs, resolves workflow IDs through the GitHub API, polls matching push runs, and reports success, failure, or timeout.
Contract tests and validation wiring .github/tests/reusable_ci_contract_test.py, .github/workflows/standards-validation.yml	Adds workflow structure, security, artifact, egress, and release-gate tests. Standards validation executes the test suite.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟡 Moderate · up to 08167

The release gate can miss a valid successful run when more than 100 newer runs exist, causing an otherwise eligible release to be rejected; merge should wait for this bounded correctness issue to be fixed or explicitly accepted.

Consider a dedicated step for the contract test.

The step is named "Parse YAML and JSON", but this command runs workflow contract assertions. A separate step, next to the community health contract step, makes a failure easier to attribute. The assertion in .github/tests/reusable_ci_contract_test.py counts only the command string, so moving the line keeps that test passing.

Check the poll budget against the job timeout.

The workflows are polled one after another. With the defaults, each workflow can consume 12 * 300s = 60 minutes, so timeout-minutes: 360 covers about six workflows. A larger workflow-files-json array hits the job timeout instead of the gate's own timeout message. Consider polling with a single shared deadline, or documenting the maximum supported array length.

Add a case for the in-progress retry path.

The current cases cover exact success, fail-closed, timeout, and input rejection. No case covers a matching run with status other than completed, which is the branch at .github/workflows/release-gate.yml lines 122-131. That branch decides whether the gate waits or fails closed, so a regression there would pass this suite. Add a fixture with an in-progress run plus a completed failure and assert that the gate waits and then reports a timeout.

Review nitpicks are dispositioned on 081678f:

• polling now runs in shared rounds, so every unresolved workflow consumes one common max-attempts/sleep budget instead of serial hour-long budgets
• an in-progress run beside a completed failure now has explicit retry/timeout coverage
• the contract command stays as the one required registration line in the existing parse/contract step to avoid widening overlap with standards-validation.yml; its failure still names the Python test directly

258-260: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Do not assert on comment prose.

Lines 258 and 259 already pin the observable contract: the query has no server-side filters. Line 260 asserts an exact prose comment that includes a date. Any rewording of that comment breaks this test without a behavior change.

♻️ Proposed change

         self.assertIn("/runs?per_page=100\"", release)
         self.assertNotRegex(release, r"runs\?[^\"\n]*(?:event|head_sha)=")
-        self.assertIn("spuriously returning 0 results since 2026-04-27", release)

If the intent is to keep the rationale discoverable, assert a stable short token such as spuriously returning 0 results instead of the dated sentence.

Scope the upload assertions to the upload steps.

The test compares whole-file counts. if: always() is a generic step condition. If any non-upload step gains or loses if: always(), this test fails with a misleading message, and an upload step that lacks the condition can still pass.

Extract each actions/upload-artifact@ step block, then assert the three settings inside that block.

Hard-coded 10-space YAML indentation in two extractors. Both sites assume a fixed body indentation width for run: | blocks. A nesting change in the workflows silently truncates or skips the extracted shell text.

• .github/tests/reusable_ci_contract_test.py#L422-L437: compute the dedent width from the first non-empty body line instead of slicing line[10:].
• .github/tests/reusable_ci_contract_test.py#L208-L209: capture the body indentation in the regex instead of matching exactly {10}, so no run: | block is skipped by the input-expression check.

472-494: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add a case where the API call fails.

The fake curl always exits 0 for run queries and always prints a body. The suite therefore never exercises the gate when GitHub returns an error or an empty body. The gate must fail closed in that case, and that is the highest-risk path for a release gate.

Add a parameter that makes the fake curl exit nonzero or print invalid JSON for run queries, then assert a nonzero return code and a clear message.

Exact-head CodeRabbit run c7e78d65-1895-4139-aa27-d891aba5dc68 has no actionable findings. The four test-only nitpicks are dispositioned without another code change:

• the dated query-filter rationale is intentionally pinned because this gate must carry the 2026-04-27 failure evidence alongside the observable unfiltered-URL assertions
• whole-workflow artifact counts intentionally enforce the fixed central topology: upload-only always(), retention, and missing-file policy must remain one-to-one
• ten-space run-body indentation is the GitHub job-step YAML shape this source contract validates; changing that structure should fail loudly rather than be dedented generically
• API failures already fail closed through set -euo pipefail plus curl --fail --show-error; the fake API boundary is focused on the exact filtering and polling decisions implemented by this gate

Verified exact head 081678f: reusable workflow contracts, release gate behavior, local standards gates, CI, CodeRabbit findings, and resolved threads are clean.
