ci(proofs): run the Agda core in CI under the PROOF-POLICY §2.1 invocation - #18
This repository never checked its own core theorems, the reclamation law R-1..R-6, in CI. proofs.yml ran only the Lean (stackcert) and Idris (Occ spike) rungs. The only runner was typed-wasm's kernel gate, at typed-wasm's pin, on Agda 2.6.3 and without the canonical flags.
This PR wires the Agda core into this repository's CI and aligns it with PROOF-POLICY (metadatastician/standards, 3-practice/PROOF-POLICY.adoc), sections 2.1, 5 and 8.
Changes
.github/workflows/proofs.yml: new agda job.
Runs scripts/check-agda.sh in debian:trixie-slim with agda-bin=2.6.4.3-1+b2, asserting the version, the same way resource-algebra's proofs.yml does.
Triggered by changes to src/OccupancyTypes/**, tests/reject/**, the gate scripts and the agda-lib.
Uses only actions/checkout@v7.0.1, already in actions.lock for this workflow, so the lock is unchanged.
scripts/check-agda.sh:
Runs under --safe --without-K --cubical-compatible (§2.1).
Scans the import cone (src/ and the pinned resource-algebra sources) for postulate outside comments (§8.4.6).
scripts/check-proofs.sh (Agda leg) and occupancy-types.agda-lib: use the same three flags.
PROOF-STATUS.adoc:
Moved to the §5 vocabulary. O-2 is ASSUMED: it is a definition the repo adopts, not a theorem. R-6 is TESTED: it is a refusal.
The CI line now names the new job.
New Proof Witness Grades section: R-1..R-5 are PWG-3 only at commits whose agda job passed, and their Rocq and Lean legs are OPEN. The existing Lean files state other theorems (stackcert, the W2.2 separation), so they are not these theorems' Lean leg.
Not changed: no Agda source, statement or proof.
Found, not fixed: scripts/check-proofs.sh agda fails, with or without this change. The manifest gates the template's verification/proofs/agda/Properties.agda, which needs the Agda standard library, and the agda-lib names a resource-algebra library that isn't installed. No CI job runs that leg. resource-algebra removed the same template file in its #14.
RSR Quality Checklist
Required
Tests pass (bash scripts/check-agda.sh, see Testing)
Code is formatted (just fmt or equivalent)
Linter is clean (no new warnings or errors)
No banned language patterns (no Python, Go, TypeScript, Deno or ReScript; JavaScript runs on Bun)
No unsafe blocks without // SAFETY: comments
No banned functions (believe_me, unsafeCoerce, Obj.magic, Admitted, sorry)
SPDX license headers present on all new/modified source files
No secrets, credentials, or .env files included
As Applicable
Documentation updated for user-facing changes
Testing
Run locally on Agda 2.6.3, the only version available in this environment:
Full gate:bash scripts/check-agda.sh against resource-algebra at the pin (0b338c9) passes: core proofs, CostIsOccupancy and DriftIsPeak refused at their invalid declarations, postulate scan clean.
Postulate scan, checked both ways: a planted postulate planted : Set in Witness.agda fails the gate.
The receipt that counts is this PR's agda job on Agda 2.6.4.3.
…ation
The reclamation law (R-1..R-6) had no CI in this repository: only
typed-wasm's kernel gate checked it, at typed-wasm's pin and Agda 2.6.3.
proofs.yml gains an `agda` job that runs scripts/check-agda.sh on Agda
2.6.4.3 (Debian agda-bin, as resource-algebra's proofs.yml), triggered
by changes to the Agda sources, rejects, gate scripts and agda-lib.
scripts/check-agda.sh runs under `--safe --without-K --cubical-compatible`
and scans the import cone (src/ and the pinned resource-algebra sources)
for `postulate` outside comments (§8.4.6). The Agda leg of
scripts/check-proofs.sh and the agda-lib flags use the same three flags.
PROOF-STATUS uses the §5 vocabulary (O-2 ASSUMED: a definition, not a
theorem; R-6 TESTED: a refusal) and records Proof Witness Grades: R-1..R-5
PWG-3 only at commits whose `agda` job passed; Rocq and Lean legs OPEN.

Automated Agda checks now run in continuous integration for relevant changes, including checks of core proofs and expected rejections.
Proof validation now uses stricter compatibility and safety settings, and flags unsupported assumptions in checked source files.
Documentation
Updated proof-status documentation to reflect the current status of proofs, verification checks and remaining work.
The workflow adds a pinned Agda job that runs the proof and expected-rejection checks. The checker adds compiler flags and scans Agda source files for postulate. The proof-status document records updated statuses and check details.
The Agda flags add --cubical-compatible and --without-K. The checker scans source files for postulate before compilation and exits with an error if it finds a match.
Run Agda checks in CI .github/workflows/proofs.yml
The workflow adds Agda source and check paths to its filters. A Debian Trixie job installs and verifies Agda 2.6.4.3, then runs scripts/check-agda.sh.
Record proof status PROOF-STATUS.adoc
The document updates the proof-status vocabulary and invocation details. It marks O-2 as assumed and R-6 as tested, and records the Agda CI job and proof-grade conditions.

The Agda checks add useful validation, but the postulate scan can incorrectly pass or reject certain source layouts and paths containing spaces. These bounded issues warrant correction or explicit follow-up.

Explanation
The title names the main change: adding an Agda core job to CI that runs under the PROOF-POLICY §2.1 invocation. The raw summary and objectives confirm a new agda job in proofs.yml, and the flags --safe, --without-K and --cubical-compatible match the title's policy reference. The title is 74 characters and 12 words, slightly long, but it stays specific and readable.
Full details: Description check
Explanation
The description follows the repository template. It has Summary, Changes, the RSR Quality Checklist, and Testing sections. The Summary and Changes explain the new agda CI job, the Agda flags, the postulate scan, and the PROOF-STATUS.adoc updates. The Testing section gives local results on Agda 2.6.3 and points to the agda job on 2.6.4.3 as the validating receipt. The Screenshots section is absent, but it is optional and marked as applicable only when relevant. The checklist marks some items as checked, and the author notes the local environment limits. The description is mostly complete.

- Around line 19-23: Update the Perl scanner in the postulate check to process
source comments in order, so text inside a line comment cannot open or close a
block comment; detect postulate only in code while preserving the existing
import-cone check and pass/fail behaviour.
- Line 19: Update the postulate scan in the Perl invocation and its find-based
file list so filenames, including those under RESOURCE_ALGEBRA_SRC with spaces,
are passed intact; also make any file read or open error fail the scan rather
than allowing a no-match result to print PASS.
- Line 19: Update the postulate scan in the `check-agda.sh` conditional to
recognise Agda syntax, ignoring occurrences inside string literals and correctly
handling nested comments before checking for the `postulate` keyword. Keep the
scan over the existing source files and preserve its current pass/fail behaviour
for actual postulates.

The postulate scan stripped `{- -}` blocks before line comments, so a
`{-` inside a `--` comment could hide a following `postulate` up to a
`-}` in a later comment. Its regex also mis-handled nested block
comments, ignored string literals, split file names on spaces, and
passed when perl could not read a file.
scripts/scan-postulates.pl reads each file in source order: `--`
comments run to the end of the line, `{- -}` comments nest, string and
character literals are skipped. It exits 2 on an unreadable file or an
empty file list. check-agda.sh passes the import cone to it as a
NUL-separated list and refuses an empty cone.
tests/scan_postulates_test.sh covers each case (comment-hidden, nested,
string, character literal, path with a space, unreadable file, no files)
and runs in proofs.yml before the gate.

`mapfile < <(find ...)` ignored find's exit status, so a directory find
could not read left a partial cone and the postulate scan could pass
without seeing every source. find now writes to a temporary file and its
failure stops the gate. Checked as an unprivileged user with an
unreadable directory under the cone: the gate stops with "could not list
the import cone".
The scanner test uses [[ ]] for its comparisons.

A stub find on PATH prints one real file of the import cone and exits
non-zero, as find does on a directory it cannot read. CI can stage this
even when it runs as root, which a chmod 000 directory cannot. The gate
must exit non-zero, say it could not list the cone, and not report the
postulate scan as passed. Against the previous check-agda.sh (find in a
process substitution) the test fails: the scan passed on the partial
list. Runs in proofs.yml after the scanner tests.

The estate code-hygiene gate (cicd-suite code-hygiene-check) reads a
whole-word STUB as an untracked debt marker and failed the Central
Estate CI/CD Audit on the heredoc delimiter. Rename it; the test is
unchanged and still passes.

Several checks are red on this PR, but none because of it. Each fails the same way on main (ce12cf7).
estate-rules: fixed here. The committed REPOSITORY-MAP.adoc was stale on main, because it lacked rows for PROOF-STATUS.adoc and occupancy-types.agda-lib. I fixed it at source in occupancy-types#19 and ported the same commit here (14276e2).
openssf-compliance. The failing step is Check no unfilled placeholder tokens (scripts/check-no-placeholders.sh .). It finds 94 files that still hold template tokens such as {{OWNER}}, {{AUTHOR_EMAIL}}, {{PROJECT_NAME}} and {{CONDUCT_EMAIL}}. They are in files like .clinerules, .devcontainer/*, .github/CODEOWNERS, .github/SECURITY.md and .machine_readable/*. The check also fails on the Dependabot PR at 9d81c2e. This repo was created from rsr-template-repo, and its identity tokens were never filled in. No fix exists yet. There is no instantiation script, and the fill needs the owner's own values, such as the conduct contact, response time and security email.
Canon lockstep. The dogfood-gate.yml job fetches canon.lock live from metadatastician/standards/main and compares it with what the repo's deed declares. The canon has moved since main's last run, and this PR touches neither the deed nor that workflow. The same check is red for the same reason on resource-algebra, mathesis and rsr-template-repo. Re-syncing the deed with the canon is a separate change.
governance, hypatia-scan, secret-scanner, main-estate-audit and rust-ci. These end in failure with zero jobs, so they fail before any job starts. They call the standards reusables at the old pin, hyperpolymath/standards@94572e6. Re-pinning them is its own change. The same re-pin in typed-wasm#284 is blocked on a repository Actions setting, and this repo will probably need the same setting.
Code Quality and Session IR (R0-B). These end in startup_failure on main as well. No fix exists yet.
This PR changes the Agda gate, the postulate scanner and its tests, proofs.yml and PROOF-STATUS. The ported map regeneration is its only other change. The new Agda job passed on Agda 2.6.4.3 with --safe --without-K --cubical-compatible, including both expected rejections.
estate-rules fails on main because the committed map is stale: the
generator now lists PROOF-STATUS.adoc and occupancy-types.agda-lib, which
the committed copy lacks. Regenerated with `just repo-map`; the output is
identical under the default and C locales.
Ported from occupancy-types#19 (b7d12c3).

## Summary
The Agda leg of `scripts/check-proofs.sh` ran `agda --safe`.
PROOF-POLICY §2.1 (`metadatastician/standards`,
`3-practice/PROOF-POLICY.adoc`) makes `agda --safe --without-K
--cubical-compatible` the canonical invocation for theory proofs,
required explicitly in local recipes and CI.
Every repository minted from the template inherits this gate, so the
template is where to fix it. hyperpolymath/resource-algebra#19 and
hyperpolymath/occupancy-types#18 make the same change in their copies.
## Changes
- `scripts/check-proofs.sh`: the `agda` case runs `agda --safe
--without-K --cubical-compatible`.
- `verification/proofs/agda/MANIFEST`: records that the template's
`Properties.agda` checks under the new flags.
- `CHANGELOG.adoc`: a *Changed* entry under `[Unreleased]`.
## RSR Quality Checklist
### Required
- [x] Tests pass (see Testing)
- [x] Code is formatted (`just fmt` or equivalent)
- [x] Linter is clean (no new warnings or errors)
- [x] No banned language patterns (no Python, Go, TypeScript or
ReScript; JavaScript runs on Bun)
- [x] No `unsafe` blocks without `// SAFETY:` comments
- [x] No banned functions (`believe_me`, `unsafeCoerce`, `Obj.magic`,
`Admitted`, `sorry`)
- [x] SPDX license headers present on all new/modified source files
- [x] No secrets, credentials, or `.env` files included
### As Applicable
- [x] `CHANGELOG` or release notes updated
## Testing
- `agda --safe --without-K --cubical-compatible -i
/usr/share/agda-stdlib -i . Properties.agda` (Agda 2.6.3, standard
library 1.7.3): exit 0. It prints `UnsupportedIndexedMatch` warnings
from the standard library, none of them errors. Plain `--safe` also
exits 0, so the change is not what makes this pass.
- I did not run `scripts/check-proofs.sh agda` end to end here. In this
environment the standard library is not registered as an Agda library,
and that leg resolves imports through the library configuration.
