Baseline method: preview 4 at +`eda5bccdbf783876980f8c535ab8c78946d31eec`. +Preceding [PR #4](https://github.com/LeiterConsulting/exec-ctrl/pull/4) merged at +20:12:17 UTC, bringing the [Ping Monitor revisit](REAL_PROJECT_PING_MONITOR.md) +and protocol refinements into main. Preserve that case's original results. + +Actual continuation prompt: "Merged. Let’s continue". This is a controlled +authoring-session extension, not an independent task-plus-link adoption trial. +Host: local Codex on Windows; exact desktop/model build unavailable. Execution uses +PowerShell 7.6.6 and Python 3.13.7; no other agent or real organization/production +system is involved. + +## Scope and acceptance + +The Go revisit covered a narrow fix. This increment covers a different boundary: +source -> built artifact -> isolated stage -> executed identity/behavior -> rollback +and release approval. The tests use stdlib zipapps, disposable files and fixed +subprocess input, with no network access or installed application changes. +The optional helper remains offline/read-only; the trusted test harness performs +the build and staging operations, never commands obtained from policy or evidence. + +Declared release facts select initiative mode with policy/Git, quality, security, +documentation, delivery, team and enterprise controls. The existing fictional +[release ruleset](../../examples/v2/release-rules.json) supplies review and +deployment/live evidence requirements. Its owner and sources are fixture labels, +not proof of an actual organization's policy or an authorized approver. + +Acceptance: + +- Observe an actual wrong staged artifact despite exit 0 and a correct computation. +- Hold the failed identity gate; a build or failed report cannot satisfy runtime + policy, even when record-local `requires` is removed. +- Restore the prior artifact, compare its SHA-256 and execute its expected behavior. +- Stage the correct built candidate, compare its SHA-256 and observe version/result. +- Keep independent approval blocked; reject a complete record with that open gate. +- Hold unavailable policy for dependent release while allowing local fixture work. +- Reject removal of a policy gate and unsupported executable policy fields. +- Keep executable metadata inert under the side-effect audit and deny opening one + fictional private canary; verify that read guard itself with a negative probe. +- Preserve fixture instructions/unfinished notes; include only explicit application + source in the artifact.

They build and execute the following artifacts: + +| Stage | Actual observation | Disposition | +| --- | --- | --- | +| Candidate build | Explicit source packaged as a runnable `.pyz`; only `__main__.py` included; expected version `fixture-v2`, input `[2,3,5]`, total 10/count 3 | Candidate test passes; no release approval inferred | +| Previous stage | `fixture-v1`, total 10/count 3 | Save exact bytes/digest for bounded rollback | +| Wrong stage | Exit 0 and total 10, but `fixture-unexpected` and a different artifact digest | Failed identity evidence retained; runtime gate unresolved | +| False pass | Runtime gate references that failed deployment evidence | Helper exits 2 | +| Recovery | Prior bytes restored; digest and `fixture-v1` result verified | Artifact rollback passes; no persisted-data recovery claimed | +| Correct stage | Staged digest equals candidate; executed `fixture-v2`, total 10/count 3 | Local fixture deployment/runtime evidence passes | +| Required review | Author source inspection cannot meet the required review kind; independent reviewer unavailable | Final record stays blocked, exit 1; falsely declaring complete exits 2 | +| Changed policy | Same policy revision label, additional test requirement | Historical record rejected by normalized policy identity, exit 2 | + +The harness checks that deleting record-local runtime requirements cannot remove +supplied-policy requirements. A separate unavailable-policy case retains a blocked +policy gate and still builds/runs a local candidate; an absent explicit ruleset +returns exit 2 rather than being treated as no policy. + +The untrusted-metadata case places fake directions to bypass approval, read a +private fixture and execute a marker write in issue text/reference metadata. +The helper is a structural reader: it does not execute those references. A +test-only named-path read guard is independently triggered, then remains enabled +for helper calls. Unsupported `command` policy fields and removing the required +approval gate are rejected. No marker/publication file appears in the fixture. + +The executable fixture deliberately demonstrates a limit of generic smoke tests: +exit success and correct business output can coexist with incorrect deployed +identity. The helper cannot discover that discrepancy from kind tags; the harness +measures it and reports failure. It also cannot authenticate reviewer independence: +even a `review` tag would remain an externally verifiable claim. These tests do +not strengthen it into a scanner, approver, permission enforcer or semantic inspector. + +## Changes from the observations + +- Add the release lifecycle and denial cases to ordinary unittest/CI discovery. + Earlier project acceptance tested source repair; this checks actual artifact and + executed fixture identity, recovery and a deliberately unclosed approval gate. +- Extend the test audit wrapper with an optional, named fictional read canary. + It is never installed as a project control or claimed as a general sandbox. +- Clarify the delivery module/playbook: check artifact identity despite a healthy + response, and verify restored identity/behavior after an abort. +- Keep the compact activation entry, helper, adapters, catalog and version unchanged. + There is no new mandatory entry read, connector, package dependency or deployment. + +## Validation and limits + +Focused release suite: three tests passed. Local repository validation passed: +10 modules and 294 supported local links. Full suite: 111 discovered tests, +109 passed and two skips because symlink creation is unavailable on this host. +`git diff --check` passed. Hosted matrix results belong to the exact publication +candidate's PR. Fixtures and artifacts are disposable; assertions and a sanitized +test log are repeatable evidence, not retained release packages or real approvals. + +The local fixture's `live` tag means a real, observed disposable subprocess, not +Splunk/game/device/production acceptance. All policy/reviewer identities are +fictional. No real company policy, approved vulnerability scanner, independent +review, team connector write, customer workload or cross-IDE adoption was exercised. +The automated suite succeeds by proving the release hold, not by granting it. diff --git a/docs/v2/PLAYBOOKS.md b/docs/v2/PLAYBOOKS.md index 5b1101b..f1a9c46 100644 --- a/docs/v2/PLAYBOOKS.md +++ b/docs/v2/PLAYBOOKS.md @@ -51,6 +51,9 @@ running artifact.
