From fc5e74937bd69504b80b23b6304095f2c6633875 Mon Sep 17 00:00:00 2001 From: Brady Gaster Date: Wed, 14 Oct 2026 14:21:45 -0700 Subject: [PATCH 1/2] feat(gh-aw): opt-in CAO research wave evidence gate Add a trusted, opt-in CAO evidence provider hook. Without a .squad/cao-evidence-provider.json descriptor, Squad behaves exactly as before. - research: hash-pinned runtime collects run-bound evidence pre-agent (App auth only in native v1; PAT fails as unsupported), native validation, immutable artifact retention, publication gate, deterministic provenance writer - triage/plan modes: restore referenced wave artifact, validate natively and via CAO --validate-bundle before the agent; failure blocks publication - manifest capability marker evidence_provider_schema; regenerated package copies, aw.yml, manifest and digests via native integrity tooling Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: c26cd4b2-4915-4ada-991d-29493af6106d --- .github/workflows/squad-ci.yml | 2 +- docs/src/content/docs/guide/gh-aw.md | 11 +- scripts/gh-aw-hosted-e2e.mjs | 8 +- test/gh-aw-evidence-provider.test.ts | 395 ++++++++++++++++ test/gh-aw-hosted-e2e.test.ts | 2 +- test/gh-aw-implement-workflow.test.ts | 2 +- test/gh-aw-quality.test.ts | 6 +- workflows/README.md | 76 +++ workflows/aw.yml | 2 + workflows/package/squad-bootstrap.md | 2 +- workflows/package/squad-deps-worker.md | 45 +- workflows/package/squad-implement-worker.md | 45 +- workflows/package/squad-retro.md | 45 +- workflows/package/squad.md | 163 ++++++- workflows/shared/squad-evidence-provider.mjs | 473 +++++++++++++++++++ workflows/shared/squad-install-verifier.mjs | 9 +- workflows/shared/squad-planning-ontology.md | 10 + workflows/shared/squad.md | 45 +- workflows/squad-bootstrap.md | 2 +- workflows/squad-workflows.manifest.json | 65 +-- workflows/squad.md | 109 +++++ 21 files changed, 1467 insertions(+), 50 deletions(-) create mode 100644 test/gh-aw-evidence-provider.test.ts create mode 100644 workflows/shared/squad-evidence-provider.mjs diff --git a/.github/workflows/squad-ci.yml b/.github/workflows/squad-ci.yml index 01f94de41..cd2d94922 100644 --- a/.github/workflows/squad-ci.yml +++ b/.github/workflows/squad-ci.yml @@ -788,7 +788,7 @@ jobs: --source-revision "$SQUAD_SOURCE_REVISION" node .github/workflows/shared/squad-install-verifier.mjs --materialize-runtime test "$(find .github/workflows -maxdepth 1 -name 'squad*.md' | wc -l | tr -d ' ')" = 8 - test "$(find .github/workflows/shared -type f ! -name 'squad-bootstrap-trigger-probe.json' | wc -l | tr -d ' ')" = 19 + test "$(find .github/workflows/shared -type f ! -name 'squad-bootstrap-trigger-probe.json' | wc -l | tr -d ' ')" = 20 test -f .github/workflows/squad-agent-binding-check.yml test "$(find .github/skills/gh-aw-enlistment -type f | wc -l | tr -d ' ')" = 1 node --input-type=module -e ' diff --git a/docs/src/content/docs/guide/gh-aw.md b/docs/src/content/docs/guide/gh-aw.md index 7ba720a78..b7b2443ae 100644 --- a/docs/src/content/docs/guide/gh-aw.md +++ b/docs/src/content/docs/guide/gh-aw.md @@ -556,7 +556,7 @@ rm -f .github/skills/agentic-workflows/SKILL.md The nested `workflows/aw.yml` is the canonical package registration.

After installation, follow the enlistment skill to materialize runtime resources, strictly compile every workflow, and verify the package-owned topology before opening the bootstrap pull request. + +## Optional CAO research evidence + +Ordinary `/squad research` remains the only per-wave user action. A normal +reviewed CAO installation may opt in by installing the receipt-owned +`.squad/cao-evidence-provider.json` and its pinned Node runtime closure. Without a +descriptor, Squad does not collect or restore CAO evidence and leaves the native +research envelope unchanged. + +The narrow descriptor uses schema `squad-evidence-provider/v1`, kind +`cao-farm-v1`, fixed entry +`.squad/cao-evidence-runtime/activity/squad-wave-evidence.mjs`, and +`runtime_files`: SHA-256 hashes keyed by the complete repository-relative paths: +the three `activity/{squad-wave-evidence,squad-farm,authentication}.mjs` files +and `.github/workflows/shared/{policy,setup-github-apps}.mjs`, all beneath +`.squad/cao-evidence-runtime/`. No arbitrary commands, URLs, runtime package +installation, issue-selected repositories, floating references or PR-head code +are supported. Descriptor, runtime and policy come only from the immutable +executing workflow checkout. `SQUAD_WORKFLOW_SHA` identifies that revision; +`GITHUB_SHA` is not a substitute. + +The trusted pre-agent gate collects a complete run-bound bundle into +`/tmp/gh-aw/agent/cao-farm/`. Its `manifest.json` uses +`cao-squad-wave-evidence/v1` and binds the control repository, workflow revision, +policy/enrollment SHA-256 digests, issue, run/attempt, capture/expiry times, +repository revisions and document hashes. `farm/evidence.json` and every other +declared document must be present, regular, hash-matching and bounded. Missing, +partial, tampered, future or expired evidence fails closed. Maximum age is +24 hours, with expiry exactly 24 hours after capture; maximum bundle size is +8 MiB and 256 files. The closed document set is `farm/INDEX.md`, +`farm/evidence.json`, and `farm/{owner}/{repo}/SNAPSHOT.md` for every enrolled +repository. Policy is `.github/workflows/cao.json`: the policy digest hashes its +raw bytes, and enrollment hashes `JSON.stringify(policy['control-plane'].scope)`. + +Before the agent starts, Squad retains that verified bundle as the control +repository's Actions artifact +`squad-cao-evidence--` (one-day retention unless gh-aw's +`vars.GH_AW_DEFAULT_ARTIFACT_RETENTION_DAYS` overrides it; the 24-hour freshness +bound still applies). The trusted publication +gate restores and validates this immutable copy before any successful safe +output. The deterministic research writer validates it again, adds a run link +and structured `evidence` provenance, and updates the native research comment. +The model cannot select the artifact or author provenance. + +The six modes `triage`, `triage revise`, `plan`, `plan revise`, `plan program`, +and `plan program revise` restore only the newest bot-authored research +artifact's referenced wave, validate it against current trusted enrollment, +and keep that lineage. If unavailable or stale, use ordinary `/squad research` +again. Committed install-time `farm/` evidence remains a historical bootstrap +baseline with unchanged receipt ownership, Cast and bootstrap validation. +Sampled issues/PRs describe capture-time observations, not an atomic snapshot. + +Credentials are step-local to collection, never forwarded to the agent. +**Native v1 supports App authentication only.** Collection requires +`vars.GH_AW_GITHUB_AUTH_MODE=app`, `vars.GH_AW_GITHUB_READ_APP_ID` and +`secrets.GH_AW_GITHUB_READ_APP_PRIVATE_KEY`, scoped to the collect step. +Other authentication modes, including PAT and workflow-token-only collection, +fail explicitly as unsupported in v1 before executing the runtime. Restore and +publication validation receive no App credentials. Azure Key +Vault credentials do not automatically become Actions secrets. If CAO Actions +read authentication is absent, this implementation fails rather than silently +asking for duplicate secrets or changing deployment/authentication settings. + +This adds no schedules, dispatch chains, target-repository writes, live +promotion, review bypasses, cast changes or attribution exceptions. Actions +artifact access follows control-repository visibility; CAO must reject visibility +leaks before collection. Hosted two-wave acceptance and live deployment remain +separate approval steps. + +Collection runs the hash-checked runtime with no arguments and the immutable +checkout as cwd. Restored bundles use `--validate-bundle` and +`SQUAD_EVIDENCE_BUNDLE`; their recorded run/attempt and workflow revision stay +bound to the research wave, not the downstream command's new run. The runtime +receives `GITHUB_REPOSITORY`, `SQUAD_WORKFLOW_SHA`, `GITHUB_RUN_ID`, +`GITHUB_RUN_ATTEMPT`, and `SQUAD_ISSUE_NUMBER`. No event-head SHA substitutes for +the executing revision. diff --git a/workflows/aw.yml b/workflows/aw.yml index 9889796e9..2b851ba61 100644 --- a/workflows/aw.yml +++ b/workflows/aw.yml @@ -35,6 +35,8 @@ resources: destination: .github/workflows/shared/squad-install-verifier.mjs - source: shared/squad-command-contract.mjs destination: .github/workflows/shared/squad-command-contract.mjs + - source: shared/squad-evidence-provider.mjs + destination: .github/workflows/shared/squad-evidence-provider.mjs - source: shared/squad-cast-validator.mjs destination: .github/workflows/shared/squad-cast-validator.mjs - source: shared/squad-bootstrap-validator.mjs diff --git a/workflows/package/squad-bootstrap.md b/workflows/package/squad-bootstrap.md index efcc6e251..cec5d6258 100644 --- a/workflows/package/squad-bootstrap.md +++ b/workflows/package/squad-bootstrap.md @@ -153,7 +153,7 @@ pre-agent-steps: node --check "$path" >/dev/null } # BEGIN GENERATED RESOURCE DIGESTS - check_hash "$install_verifier" "a8b8fedd8b2804a061c367f6c67113979aa9d792526e8d052a2f01f697bf3642" + check_hash "$install_verifier" "d12cf4de38e716dd6d0bbb03fda22675477a4559573d3a8601b8f5b2f88f544e" check_hash "$cast_validator" "15f0d47917d269b5b967dc2a782a0eb761c39af7a92ddb64fed687a427070760" check_hash "$bootstrap_validator" "d552d041f006249bfaa67b10a75877f813796b7698c718ac7eb7cf16f3a72e31" # END GENERATED RESOURCE DIGESTS diff --git a/workflows/package/squad-deps-worker.md b/workflows/package/squad-deps-worker.md index 19c056077..25a4dc758 100644 --- a/workflows/package/squad-deps-worker.md +++ b/workflows/package/squad-deps-worker.md @@ -10,6 +10,8 @@ safe-outputs: needs: safe_outputs if: needs.safe_outputs.result == 'success' permissions: + actions: read + contents: read issues: write pull-requests: write max: 1 @@ -20,13 +22,47 @@ safe-outputs: required: true type: string steps: + - name: Checkout immutable research writer + uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 + with: + ref: ${{ github.workflow_sha }} + persist-credentials: false + path: .squad-evidence-trusted-base + - name: Determine installed evidence provider + id: research-evidence-required + uses: actions/github-script@3a2844b7e9c422d3c10d287c895573f7108da1b3 + with: + script: | + const { join } = require('node:path'); + const { pathToFileURL } = require('node:url'); + const root = join(process.env.GITHUB_WORKSPACE, '.squad-evidence-trusted-base'); + const evidence = await import(pathToFileURL(join(root, + '.github/workflows/shared/squad-evidence-provider.mjs')).href); + core.setOutput('enabled', Boolean(evidence.readProvider(root))); + - name: Restore immutable research evidence + if: steps.research-evidence-required.outputs.enabled == 'true' + uses: actions/download-artifact@v8.0.1 + with: + name: squad-cao-evidence-${{ github.run_id }}-${{ github.run_attempt }} + path: /tmp/squad-writer-evidence - name: Upsert Squad research artifact uses: actions/github-script@v9 env: ISSUE_NUMBER: ${{ github.event.issue.number || github.event.pull_request.number || github.event.inputs.issue_number }} + SQUAD_ISSUE_NUMBER: ${{ github.event.inputs.issue_number || github.event.issue.number || github.event.pull_request.number }} + SQUAD_WORKFLOW_SHA: ${{ github.workflow_sha }} with: script: | const { readFileSync } = await import("node:fs"); + const { join } = await import("node:path"); + const { pathToFileURL } = await import("node:url"); + const root = join(process.env.GITHUB_WORKSPACE, '.squad-evidence-trusted-base'); + const evidence = await import(pathToFileURL(join(root, + '.github/workflows/shared/squad-evidence-provider.mjs')).href); + const wave = evidence.readProvider(root) + ?

Validate descriptive source paths separately from extracted bundle paths so spaces and bracketed route names are accepted. Restore the referenced successful workflow attempt rather than the latest rerun, retaining exact producer identity and all bundle validation gates. Add direct path and retry regressions and regenerate the runtime digest. Closes #2226 review findings.
