Kernel: a Lens run by GitHub Actions is read only from its own workflow file - #114
Merged

Conversation
…ow file GitHub Actions is one App, 15368, for every job in the repo, one a pull request adds on its own branch among them. A Lens Actions runs is now pinned to its workflow file as well as its App. - The facts carry, for each check, `workflow`: the path of its check suite's workflow run, or null for a check no workflow ran. The configuration names each deterministic Lens's file: verify is .github/workflows/verify.yml, the secret scan .github/workflows/ci.yml, code-scanning null. - A check under a Lens's check name from its own App and another file, or with no file read, leaves the Lens unreadable as another App's check does (check_unreadable, evidence `<lens>:from_workflow:<path>`, the path `unreadable` when none was read), on a queued item too, and moves nothing. A Lens that names no file is read only from a check that names none. - tools/check_workflows.py holds the configuration to the real files: each file a Lens names exists and runs a job under its check name. - The simulator's impostor fault posts a passing check from another workflow file of the Lens's own App, beside the one from another App. - Platform facts, unverified: the workflow file is readable (P-35), and an upload to code scanning under CodeQL's tool and category cannot replace the CodeQL verdict (P-36), in sim/grounding.py and design section 6. - Decision 0017 replaces 0015 and adds the ruling. Pinning each required check's App in the main ruleset stays the Maintainer's, with "The Factory repo's rulesets hold the Release tags and each required check's App" (issue 62).

…workflow file "Session hooks" (pull request 109) adds its own record 0017, so this one is numbered 0018: its file name and title, and 0015's "replaced by" Status. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…reads The review and security passes on the pin to a Lens's workflow file. - Decision 0018 and the design say the pin holds the workflow file's path, not its content or what it runs, and name what does hold .github/ today, and the gap: "Kernel: a change to the Factory's own rules or a Lens's inputs needs a person" (issue 113). - A Decision shows a workflow path only in the configuration's form (.github/workflows/, ASCII letters, digits, . _ -, .yml or .yaml) and no longer than the new limit max_path_length; any other, dynamic/ paths among them, is shown unreadable. - tools/check_workflows.py: a Lens of GitHub Actions names a workflow file and no other Lens names one; only jobs.<id>.name, or the id, names the check; a Lens job with a matrix, a job-level if: or uses:, or a workflow not on both pull_request and merge_group, is refused. No job is granted security-events: write. - tools/check_apps.py: no Factory App holds workflows or security_events. - The simulator asserts the Kernel showed from_workflow evidence. - Trial P-35 asks where a check's workflow path comes from and in what form; P-36 says how its fallback is held.

Part of the epic "Epic: slice 0, foundations. The repo holds the line, its context is tested, and the platform facts are recorded". Part of #97: its third item, the
mainruleset pinning each required check's App, is the Maintainer's in GitHub and stays with "The Factory repo's rulesets hold the Release tags and each required check's App" (#62)."Kernel: a Lens is read only from the App that reports it" (#98) pinned each required Lens to its App. GitHub Actions is one App (15368) for every job in the repo, including one a pull request adds on its own branch with the same name.
The rule
facts.checks[].workflowis the workflow file of the run that made the check (the port reads it from the check suite's workflow run, verbatim, or null). Each entry ofrequired_lenses.deterministicnames itsworkflow:.github/workflows/verify.ymlforverify,.github/workflows/ci.ymlforSecret scan (gitleaks), null forCodeQL(App 57789, run by no workflow).check_unreadable, read before any Lens's failure; a queued item leaves the queue; it moves nothing (Kernel: when waiting becomes the Maintainer's to see #94).<lens>:from_workflow:<path>only when the path has the configuration's form (.github/workflows/<name>.yml|yaml, ASCII, at mostlimits.max_path_length), and…:from_workflow:unreadableotherwise, so no outside text reaches a Decision.tools/check_workflows.pyholds the configuration to the files: a Lens run by Actions names a workflow and no other does; the file exists and runs a job under the Lens's check name (itsjobs.<id>.name, or its id), onpull_requestandmerge_group, with no matrix, job-levelif:oruses:.What the pin does not hold
The pin holds the workflow file's path, not its content or what it runs. A pull request from a branch of this repo, or a Dependabot security update (class
dependency, no model review), can edit.github/workflows/verify.ymlin place and still report from that path;verifyruns the pull request's ownMakefile,tools/andtests/, and the secret scan reads its.gitleaks.toml. What holds.github/today: no Factory App holdsworkflows(now checked bytools/check_apps.py), so GitHub refuses an App's push there; fork admission (I-36);applyfor Roles, waiting onharness/; and the session hooks, locally. Themainruleset requires no review and pins onlyverify. The gap is "Kernel: a change to the Factory's own rules or a Lens's inputs needs a person" (#113).Recorded, unverified
Trial P-35 asks whether a check run names the workflow that ran it, in what form, whether CodeQL's has none, and where a check run created through the API with
checks: writelands. Trial P-36 asks whether an upload to code scanning under CodeQL's tool and category can replace its verdict; no Factory App holdssecurity_events(checked), and the workflow lint now refuses a job-levelsecurity-events: write.Decision
