ci(release): require a reportable gate and promote only tested artifacts (#632)#648defangdevs wants to merge 9 commits into
Conversation
Symptom (issue #632): anything pushed to master became the public install default within minutes, tested or not. The branch ruleset requires no status check, publish-template.yml ran on every push independently of CI and of the fresh-boot deployment test, and it re-resolved the nixos-unstable channel at publish time - so the box a 1-click Launch button creates had never been booted by anything, and its one mutable dependency was resolved after the last thing that could have tested it. Requiring green CI was not possible either. The expensive jobs were filtered on their workflow TRIGGERS, and a workflow that never starts reports no check run at all - so a required check would have left every docs-only pull request pending forever on something nothing would report. Two halves. The gate. The path filters move out of the triggers into .github/path-filters/*.paths, read by a cheap always-running `changes` job (scripts/changed_paths.py reimplements GitHub's own glob dialect, so the lists move across unrewritten, comments and all). The expensive job is `if:`-guarded on its answer, and each workflow ends in a terminal `gate` job that runs with `if: always()` and reports either way - including the case a plain "did validate pass?" would get wrong, where the guard skipped the job although the paths did change. `CI gate`, `AWS template gate` and `Azure template gate` are now reported on every push and every pull request, so they can be required. The promotion. scripts/release_manifest.py records a candidate's exact identities once - rev, the SRI hash of modules/agent-box.nix the EC2 template fetches, the flake ref the Lightsail template installs, the flake.lock hash, the resolved nixpkgs channel SNAPSHOT and its hash, and a hash per template. promote.yml is the only path to the public defaults: it refuses a candidate whose gates are not green (an ABSENT gate is a failure), builds the manifest once, boots THAT candidate in deploy-test with those pins, publishes the same manifest's pins, and only then tags it, cuts a Release carrying the manifest, and moves the `release` pointer. A failure anywhere before publishing leaves the public defaults untouched. deploy-test.yml gains a workflow_call interface and passes the nixpkgs pair through to CloudFormation; it previously left AgentNixpkgsUrl empty while publish injected a pair it resolved itself, so the tested box and the 1-click box were never the same artifact. publish-template.yml no longer triggers on push and computes nothing: it injects what the manifest recorded, after verifying the manifest describes exactly the commit being published, and uploads the manifest to S3 beside the templates. Issue #408 cannot come back - the pin and the template are always one candidate's now. Master running ahead of the last promoted release is the intent, not that bug. Checks: changed-paths and release-manifest, both native and hermetic, wired into flake.nix and into ci.yml's native list. Still needs a repo admin: adding the three gates to the branch ruleset as required status checks, and deciding the approving-review count. See the PR and the comment on #632.

Merge Risk: 🟡 Moderate · up to Release publishing and CI gating are reworked so only tested artifacts become public defaults. Two behaviors should be settled before merge: a manual republish of an existing release tag re-resolves dependency pins and can publish versions that were never deployment-tested, and the deployment-test workflow inserts a supplied password directly into a shell command after cloud credentials are configured. A partially failed publish can also leave the public templates and their recorded pins inconsistent.

… both ways Three real defects from the review, plus two test/robustness gaps. promote.yml wrote its deploy-test pins as `echo "k=$(m ...)"`. Under `bash -e` that step's status is echo's own, so a failing `release_manifest.py field` was discarded and an EMPTY pin reached GITHUB_OUTPUT - which deploy-test reads as "base channel" and boots an unpinned box, the exact divergence promotion exists to prevent. Verified: `bash -ec 'echo "k=$(false)"; echo reached'` prints `k=` and reaches the next line, while `bash -ec 'x=$(false)'` exits 1. Assign first. deploy-test.yml's nixpkgs pair guard only fired for a url with no hash, never the reverse, though both leave the same malformed state. Both directions now, checked over all six input combinations. release_manifest.py's nix-prefetch-url call had no timeout, and it downloads a channel tarball. A stall would have run the job out of its own timeout - reported `cancelled`, which this repo documents as indistinguishable from a supersede and therefore invisible. Bounded at 900s, raising ManifestError with the URL. Tests: a CLI case for the `field` verb (the verb both workflows inject public template `Default:` values from, whose contract is that a missing or empty path exits non-zero - a blank Default still lints and still publishes), and the empty-filter fixture moved to a temporary directory so a local run cannot leave it in the source tree.

addressed in 4c73579 (all five findings: the echo/set -e pin bug, the one-directional pair guard, the unbounded prefetch, the missing field CLI test, and the in-tree fixture)
That job installs no Nix, so nix-prefetch-url is not there to re-hash the channel tarball - and the publish job, which does have it, already ran the full verification including that hash before anything was uploaded. The env var alone did not say either of those things. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BUoJKvnW1qN6onxZt6ui1S

Code review for #632, scoped to single-user VMs for v1. Changes are needed before release: five findings below. Local manifest/path tests pass (21 + 20 tests), but they do not cover these workflow-level paths. No cloud resources were launched or public artifacts modified during this review.

[P1] Enforce the promotion gate on every publication entry point
A manual dispatch with ref=master reaches this build and then the S3 upload without checking any CI result, prior release record, or deployment test. The comment restricts this to re-publishing releases, but the code does not. promote.yml also accepts skip_deploy_test for a never-promoted commit. Both paths can publish an untested candidate, defeating #632. Remove the standalone publish dispatch or require an existing successful promotion and its recorded manifest; validate the same prerequisite before allowing skip_deploy_test.

Not fixed here - this duplicates already-filed issue #639 ("E2E test should use lightsail"), opened with the same diagnosis: deploy-test.yml only ever boots deploy/aws/template.yaml, never lightsail-template.yaml, even though Lightsail is the actual 1-click default. That issue is a comment rather than a PR because two things can't be settled from this box: the IAM grant a Lightsail leg needs on the defang-agent-box environment's role (a different AWS account than this box's own credentials reach), and a design choice between adding a third matrix leg or replacing ipv4-full with one - both real trade-offs for a human to weigh, not something to fold into this PR's scope. Left for #639 rather than re-decided here.

Resolve conflicts in aws-ci.yml and ci.yml: master added a docs/vendor integrity check to aws-ci.yml's validate job and several new native checks to ci.yml's list. Kept this branch's path-filter mechanism (dropping the inline `paths:` block aws-ci.yml no longer needs) and added docs/vendor.json + check_docs_vendor.py to aws-ci.paths so the gate still covers them; merged the native-checks list and its description comment.
…flagged Four review findings from PR #648, all confirmed against the code: - publish-template.yml's manual workflow_dispatch built and published a manifest for ANY ref with no check that it had ever been promoted - the input's own description claimed this was "for re-publishing" but nothing enforced it. Now refused unless the commit carries a release-* tag. - promote.yml's skip_deploy_test accepted a commit that was never promoted before, publishing it with no fresh-boot result at all. Now refused unless the commit carries a release-* tag. - Every promotion - including a rollback - called release_manifest.py build(), which re-resolves the nixos-unstable channel and can hand the same source sha different dependency pins than what was actually tested. A rollback now downloads and verifies the ORIGINAL manifest from its Release instead of rebuilding one. - promote.yml's top-level checkout has no `ref:` (it must resolve `sha` from full history first), so its working tree sits at the dispatch ref, not at the candidate. Hashing "." there hashed the wrong tree whenever the candidate was not the tip - release_manifest.py's own remote check caught the mismatch and failed loudly, but a candidate other than the tip could then never be promoted. Now checked out into its own worktree before the manifest is built or reused. - The allow_rollback ancestry check ran only in the `record` job's final push, after publish had already replaced the public S3 templates. Preflighted in the `candidate` job instead, before any public write; the final push stays as the concurrency-safe check. A fifth finding - deploy-test.yml only ever boots the EC2 template, never the Lightsail one that's actually the public 1-click default - duplicates already-filed issue #639, which is blocked on an IAM grant to an environment this box can't administer and a leg-design choice for a human. Left for that issue rather than re-decided here. Local tests: tests/test-release-manifest.py (21) and tests/test-changed-paths.py (20) both green; all workflow YAML parses and every `run:` block passes `bash -n`.

Addressed the review, in 2583995 (pushed after rebasing onto master, which had drifted since 1f930e9 - conflicts were only in aws-ci.yml/ci.yml, both cosmetic to resolve). Four of the five findings fixed and replied to inline:
Left as-is, with a reply linking it: the Lightsail fresh-boot gap (both P1s about it) duplicates already-filed #639, which is blocked on an IAM grant to an environment I can't administer from here and a leg-design call that's genuinely yours to make, not something to fold into this PR.

Rebased (merged `origin/master` onto the branch — master had moved 5 commits since the last sync, so a merge redid less work than a pure rebase would have). Two real conflicts:
That second one also required updating CI is running on the pushed commit now (aws-ci.yml/ci.yml/azure-ci.yml gates). Not merging — this PR's own body says not to. |

…timeout CodeRabbit flagged PREFETCH_TIMEOUT at exactly 900s (== the candidate job's 15-minute timeout-minutes), so a stalled prefetch would be killed by the job timeout before the subprocess timeout could raise ManifestError - reported as `cancelled`, indistinguishable from a supersede per this repo's own documented convention.

CodeRabbit flagged (CWE-78, critical): inputs.web_password was interpolated directly into the `run:` script text, so a workflow_dispatch caller could break out of the quoted assignment with a single quote and run arbitrary shell on a runner that had just assumed the AWS OIDC role. Passed through `env:` instead, and refused a value containing a newline or carriage return before it reaches anything downstream.

…igger CodeRabbit caught this doc paragraph left over from before #632: it still described the workflow as only running on paths that touch AWS files, which stopped being true once the trigger-level paths: filter moved into .github/path-filters/aws-ci.paths and the workflow itself now always starts.

CodeRabbit's fresh review after the rebase raised one real actionable finding plus a couple of drive-by ones I fixed while I was in there, since they're genuine and cheap:

Addresses #632.
Do not auto-merge this. The workflow changes are testable and tested; the policy in them (what "promoted" means, and that nothing publishes on a push any more) is a maintainer's call, and one step of the issue's own fix needs repo-admin access this PR cannot reach. Details at the bottom.
The symptom
Anything pushed to
masterbecame the public install default within minutes, tested or not:rules/branches- this repo's ownAGENTS.mdalready documented it: "gh pr merge NNN --squash --autois not a promise to wait for green here");publish-template.ymlran on every push to master, independently of CI and ofdeploy-test.yml;That last one is worth stating precisely, because it is the part a commit sha cannot describe.
deploy-testpinnedAgentBoxRev/AgentBoxSha256to the triggering commit and leftAgentNixpkgsUrl/AgentNixpkgsSha256empty, so the box it booted tracked whatever the channel was at boot.publish-templateresolved that channel itself and injected the pair it happened to get. The tested box and the 1-click box were never the same artifact.And requiring green CI was not possible either. The expensive jobs were filtered on their workflow triggers, and a workflow that never starts reports no check run at all - so a required check would have left every docs-only PR pending forever on something nothing would ever report. That is the issue's step 2, and it has to be fixed before step 1 can be done at all.
What changed
1. A gate that is always reported
The path filters move out of the triggers into
.github/path-filters/*.paths, read by a cheap always-runningchangesjob.scripts/changed_paths.pyreimplements GitHub's ownpathsglob dialect, so the lists moved across unrewritten - comments and all, which is why they are plain text and not JSON: every entry carries a note saying which bug put it there.Each of
ci.yml,aws-ci.yml,azure-ci.ymlthen ends in a terminalgatejob withif: always():changesvalidategateCI gate,AWS template gate,Azure template gateThe gate reports what actually happened rather than what ran, including the case a plain "did validate pass?" would get wrong:
validateskipped whilebuild == 'true'is a failure, because that means the guard expression on the job is broken. All six decision paths were exercised locally against the extracted step script (success/skipped/failure/cancelled, and a failedchanges).2. A release manifest, built once
scripts/release_manifest.pyrecords a candidate's exact identities, resolving each exactly once:verifyrecomputes every field from the rev the manifest names and refuses any difference. It deliberately re-hashes the recorded channel URL rather than re-resolving the channel - re-resolving would compare an old release against wherever unstable has since moved, which would make every rollback unverifiable.A real manifest, built here against
98eaa46(network +nix-prefetch-url):{ "agent_nixpkgs": { "channel": "https://channels.nixos.org/nixos-unstable", "sha256": "15p6r29c2qz8rch0a2ni5v1qfz9kjgrd4jklbj5qvqdagikrvqdb", "url": "https://releases.nixos.org/nixos/unstable/nixos-26.11pre1070770.8ce4ef6cb6f8/nixexprs.tar.xz" }, "flake_lock_sha256": "5ea4edb99a50185aa228d080b9cee397fee28ebdc0463c46b774a807bebe880d", "flake_ref": "github:defangdevs/agent-box/98eaa467acb688ae9c2e4b8ecd158ec473988e11", "module_sha256": "sha256-UrVpqMJE5t9On5LE9nJpsHUcSH0VfR/iVG3l5/hitUU=", "rev": "98eaa467acb688ae9c2e4b8ecd158ec473988e11", "templates": { "deploy/aws/lightsail-template.yaml": "6b2c59da8284077e8df6a8a1178f1dda99b1c4519437e5fb726c9f90853ff57c", "deploy/aws/template.yaml": "59856eb95f2b5d12d10d447f48d5077f3dc58a75a1d9611051c41cdbca65bf20" } }Note
channels.nixos.org/nixos-unstableresolving to a dated, immutable snapshot. Recording the target is what turns "we built against unstable" into a dependency identity.3. Explicit promotion
promote.ymlis now the only path to the public defaults. In order, stopping at the first failure:successfor that exact sha - and an absent gate is a failure, which is the whole reason they are separate always-running jobs. Requiring them here as well as in the ruleset matters: a ruleset governs the merge and an admin can bypass one, while nothing reaches the public install default without passing this step;deploy-test.yml(nowworkflow_call-able) with the manifest's own pins, so the box that boots is pinned to the same source and the same dependency set the published templates will carry;publish-template.ymlwith the same manifest - it computes nothing now, verifies the manifest describes exactly the commit being published, injects only what was recorded, and uploads the manifest to S3 beside the templates;release-*tag, a GitHub Release carrying the manifest, and thereleasebranch pointer.A failure anywhere before 5 leaves the public defaults exactly as they were.
4. Install and update paths
publish-template.ymlno longer triggers on push.agent-box-sourcealready takes a ref (AGENT_BOX_SRC_REF) or a branch (AGENT_BOX_SRC_BRANCH), soagentbox update --branch release/selfUpdate.branch = "release"needs no code change and is documented. I deliberately did not change the shipped default: it changes what every existing box updates to, and it needs a promotion to exist first. That is a maintainer's call (see below).5. Rollback
Dispatch
promote.ymlwithshaat an earlier promoted commit,allow_rollbackon,skip_deploy_teston (that candidate already passed it). It keeps the tag it already has - a commit is tagged at most once, so the history of what was public stays readable - rebuilds the manifest from its own immutable rev, republishes, and force-movesrelease. Per box:agentbox update --rev <release tag> --force.The tag/rollback shell was exercised against a scratch repo with a real remote: first promotion tags, re-promotion reuses the tag, promoting an older commit tags it, the
releasepointer fast-forwards, a backwards push is refused withoutallow_rollbackand succeeds with it.Checks run
Two new native, hermetic checks, wired into
flake.nixand intoci.yml's native list (perAGENTS.md: the flake is not enough):changed-paths(20 tests) - the glob dialect, the committed filter files against the concrete paths whose bug histories put them in the list, and the part nothing else can see: that no gated workflow has grown a trigger-levelpaths:again. Both wiring assertions were negative-controlled (re-addingpaths:toci.yml, and commenting out a filter entry, each turn them red).release-manifest(20 tests) - weighted at the refusals, because a manifest that verifies when it should not looks exactly like a pass: a changed module, a changed template, a changedflake.lock, another rev, an unpinned channel, aflake_refnaming a different commit, and a short/branch-shaped rev each get an assertion. No network;nix-prefetch-urlis a stub the test writes itself.Also run here:
actionlintover all workflows, both in CI's mode (-shellcheck=) and with shellcheck on the three files this PR rewrites - clean under both (the ten pre-existingdeploy-test.ymlfindings are why CI passes-shellcheck=).flake8over the two new scripts and their tests - clean.nix build --keep-goingover all 38aarch64-linuxflake checks - still running as I open this; I will post the result rather than claim it, and CI's own run is the authority.changed-pathsandrelease-manifestchecks specifically confirmed inside the Nix sandbox, not just natively (the one git-dependent case skips there and says so).Two things I did not do, and one thing that needs an admin
Needs repo-admin (the issue's step 1, and the part I stopped at deliberately). Adding required status checks to the ruleset is a repo-settings change. I have the token rights, and did not use them, for a concrete reason: the gates do not exist on any currently-open PR's branch, so requiring them today would make five in-flight PRs permanently unmergeable until each is rebased. The change has to land first. The exact call, ready to run after merge, is in a comment on #632 along with the approving-review question, which is a real judgment call and not mine to make.
Where "promoted" state lives was the one genuinely open design question, so per this repo's own "when to skip straight to the PR" rule here is the recommendation rather than a silent choice: a
release-*tag plus a GitHub Release as the record of truth, and areleasebranch as the pointer boxes follow. Not one or the other. The tag and Release are immutable and carry the manifest, which is what an audit needs; the branch is whatagent-box-source's fast-forward guard is written around, so a box tracking it moves from tested release to tested release and never through an untested tip. A moving tag would be a lie about tags, and a branch alone carries no manifest. Both point at the same commit. Say so if you would rather have only one.An observation, left alone on purpose. The filter lists are byte-equivalent to the trigger lists they replaced, so this PR does not change which changes run CI beyond its own additions. But those lists have a pre-existing gap:
tests/test-settings-json.py,tests/test-webhook-self.shand friends are flake-check sources that no pattern matches, so editing one alone runs nothing. Widening totests/**would also run the full VM suite on every test edit, which is a CI-cost call rather than a bug fix - happy to do it here or separately, but not silently in a PR about gating.User-visible and security effects
promote.yml'srecordjob needscontents: writeto push the tag and thereleasepointer. If a ruleset is later added overrelease, the Actions token needs a bypass entry or promotion will fail at the last step.s3:PutObjecttarget (release-manifest.json, added to the existing public-read policy alongside the two templates).🤖 Generated with Claude Code
