proofs: record theory grades as PROOF-POLICY §8 PWG; scan the import cone - #170
januskey's grade records were written against the mathesis brief on 2026-11-01. The owner ruling of 2026-11-04 then made standards3-practice/PROOF-POLICY.adoc §8 normative for grades and kept the brief for provenance only. This PR brings the records in line with §8 and adds the postulate scan that §8.4 asks for.
Records (PROOF-NEEDS.adoc, docs/theory/PROOF-GRADES.adoc)
Grade labels. The five theory rows (G-1, T-1, T-2, T-3, E-1m) are PWG-3, written with the prefix §8 requires. The brief's "2ii needs Isabelle/HOL" becomes §8.3's +foundation-diverse tag.
Receipt. Run 42076969251 at 23bc8c3 is recorded as the last receipt for the modules. Because this PR changes the checker, the grade reads PWG-3, receipt pending re-run. The first green agda-proofs.yml run on main after merge is the new receipt; a follow-up PR records it and marks 42076969251 superseded. Runs 41687715055 and 40867211509 are already superseded. The record names the prover pin, flags, import cone and axioms.
Row counts. The page's duplicated counts had drifted from the ledger, so they are removed, and PROOF-NEEDS holds the only count.
Rust verifiers. These now read Creusot with Pearlite, and Verus (§1.2, 2026-11-07).
Import cone from Agda. The cone is the module set Agda reports with --dependency-graph for the three roots: 6 first-party modules plus 8 supplied with the prover. Each module is resolved to its source file, and an unresolved module fails the gate.
Scan, lexed as Agda lexes. The scan skips nested {- -} comments, and a comment separates tokens. It skips -- comments that start a token (x--y stays a name), and string and character literals. Pragma bodies are skipped to the first #-}: Agda does not nest comments inside a pragma, and this rule can end a pragma early but never late. Whitespace is Agda's own: every isSpace character except tab and newline, including NO-BREAK SPACE and the Unicode space separators.
Prover trusted base. The only postulates allowed among the prover-supplied modules are in Agda.Primitive. Its blocks must declare exactly Level, lzero, lsuc and _⊔_, each with its BUILTIN binding. Any other prover-supplied postulate fails the gate.
Controls. Every run writes two controls to a temp directory. The comments-only control (comments, strings, x--y names, a FOREIGN payload) must exit 0. The planted control must exit 1 and name all four of its postulates: after a block comment, bounded by NO-BREAK SPACE, separated by a block comment, and after a pragma whose payload holds {- {-.
Testing

Result
CI agda-proofs.yml on 77fcedb (Agda 2.6.4.3, pinned)
green: cone 6 + 8, 0 postulates in the first-party modules, both controls pass, 6 rejections refused as named
bash scripts/check-agda.sh locally at 9ff3043 (Agda 2.6.3, Ubuntu)

Scanner cases (27), under both mawk and gawk
all pass. The scanner at 77fcedb missed the 11 whitespace cases. The scanner at c728a8c missed the comment-separator case and the {- {--in-pragma case, and wrongly flagged FOREIGN payloads
Agda.Primitive mutations against the 2.6.4.3 file
each fails the gate: added block, fifth name, removed BUILTIN LEVELSUC, inline private postulate, comment-separated postulate{- c -}hidden, and a postulate in Agda.Builtin.Bool. The unmodified 2.6.3 and 2.6.4.3 files pass
shellcheck on both scripts; gitleaks
clean
Not done here
Literate Agda is not resolved. The gate fails closed with "cannot resolve module" if a literate module ever enters the cone. None is in the cone today.
dashboard-check.yml still installs Agda 2.6.3 while the proof gate pins 2.6.4.3. Under §6 that needs a deviation record or one shared pin.
.claude/CLAUDE.md still points at .machine_readable/6a2/*.a2ml. A2ML is retired, so this pointer is stale; it is left for a separate change.
…cone
The grade records were written against the mathesis brief on 2026-11-01,
before the owner ruling of 2026-11-04 made PROOF-POLICY §8 normative:
- The five theory rows (G-1, T-1, T-2, T-3, E-1m) are PWG-3, written with
the prefix. The brief's "2ii needs Isabelle/HOL" is replaced by §8.3's
+foundation-diverse tag.
- The receipt is the current green agda-proofs run 42076969251 at 23bc8c3,
covering all three modules under the §2.1 canonical invocation, with
library pin, flags, import cone and axioms recorded. Runs 41687715055 and
40867211509 are kept as state: superseded. The page had still cited the
pre-flag receipt it said it would replace.
- The duplicated row counts, which had drifted (23 against 27 TESTED), are
removed from PROOF-GRADES; PROOF-NEEDS stays the only count.
- Rust's verifiers read Creusot/Pearlite and Verus (§1.2, 2026-11-07).
§8.4 asks for a comment-aware postulate scan of the import cone beside
--safe. scripts/scan-postulates.sh does that, and check-agda.sh runs it on
the proofs and the pinned resource-algebra sibling with a negative and a
positive control written at run time. Verified locally: cone 10 files, 0
postulates; a mutant scan that reports nothing fails the gate.

Updated proof-grade guidance and status records, including the current Agda verification evidence and the status of Rust, Rocq and Lean verification.
Clarified how proof grades relate to claim statuses and engineering contracts.
Quality Checks
Added checks that detect Agda postulates while ignoring comments, with control cases to verify the checks behave as expected.
The documentation adopts Proof Policy §8 Proof Witness Grades and updates the Agda receipt and grade records. The Agda validation script now uses a comment-aware postulate scanner, which also checks comment-only and planted-postulate cases.
Changes: Proof Witness Grades
Layer / File(s)
Summary
Grade policy and applicability PROOF-NEEDS.adoc, docs/theory/PROOF-GRADES.adoc
The documents identify Proof Policy §8 as the authority for Proof Witness Grades, use PWG labels, and update the Rust verification mapping. The theory page no longer duplicates ledger totals and statuses.
Agda receipt and grade evidence PROOF-NEEDS.adoc, docs/theory/PROOF-GRADES.adoc
The documents record the three-module Agda receipt, its invocation and import cone, the grade rationale, and receipt states. They identify unavailable Rocq and Lean legs and state that the Rust verifiers have no contract or proof in the tree.
Postulate scanning and validation scripts/scan-postulates.sh, scripts/check-agda.sh
The new scanner detects postulate outside comments in Agda files. The Agda check script runs it and checks comment-only and planted-postulate control cases.
hyperpolymath/januskey#166: Introduced the proof-grade documents and earlier Agda receipt that this PR updates.
Merge Risk: Low · up to 47700
The changes have bounded documentation and validation risks: valid source can be rejected, scan coverage can be overstated, and the cited receipt predates the changed checker. Correct these limitations or explicitly accept them; no invalid-proof acceptance is established.

…comments
Stacked on #170, which records the theory grades as PROOF-POLICY §8
PWG-3 and adds the postulate scan. This adds what #170 does not cover.
The ledger lost #168's T-8 and T-9 rows: main still showed T-8 OPEN
("not yet built") although its five tests are green in CI and locally,
and T-9 existed only in prose. T-8 now has one TESTED row per test,
T-9 is an OPEN row in both tables, and E-1m gains its missing
status-table row so the two tables agree.
A PWG census with its denominator (§8.4.7): PWG-3 5 of 6 theory
theorems, G-3 ungraded. The Rocq and Lean legs are recorded as not
attempted (OPEN) rather than `unavailable`: under §2 that route means a
leg that cannot be built, and a hand re-proof is always the fallback.
Two proof files had misleading comments, though no statement or proof
changed. TransactionAtomicity's "What is NOT claimed" block described
non-atomic saves and a non-resumable rollback, both since fixed (T-4,
T-5, T-8). Reversibility implied that the 𝟙 grade of a wrap/unwrap pair
derives from its cancellation law; the grade is assigned. The G-1 and
E-1m wording now says so, and the receipt notes the re-earn.

Inline comments:
Review comments at @docs/theory/PROOF-GRADES.adoc:
- Around line 49-50: Update the Rust guidance in the engineering mapping and
“What moves them” table to include Verus alongside Creusot, consistent with
§1.2. Preserve that verifier scopes may differ and that qualifying Verus proofs
need not be duplicated in Creusot.
- Around line 108-112: Update the Import cone record for Epistemic.agda to
include its Agda-installed built-in imports, and ensure the cone scan covers
them as required by §8.4. Preserve the existing source re-check and flags while
recording the complete cone.
- Around line 97-99: Update the CI receipt in PROOF-GRADES so it does not
present run 42076969251 as current evidence for the checker after the postulate
scan changed. Preserve that run as historical evidence, and record a passing CI
run that includes the scan before marking the receipt and grades as current.
- Around line 228-230: Remove the stale count of 23 TESTED rows from the
engineering-contract section, keeping its statement free of a row census and
consistent with the page’s note that PROOF-NEEDS.adoc is the sole source for
counts.
Review comments at @scripts/check-agda.sh:
- Around line 38-40: Update the planted-postulate control in the check script to
require `scan-postulates.sh` to exit with status 1 and to verify its output
identifies the planted postulate. Treat any other status, including 2, or
missing identification as a failed check.
- Line 25: Update the scan-postulates.sh invocation in the Agda check so it
scans only modules in the proofs’ actual import cone, rather than all of the
resource-algebra source tree. Establish and use the existing import-cone
mechanism without changing the selected revision or weakening checks on imported
modules.
Review comments at @scripts/scan-postulates.sh:
- Around line 24-30: Update the scanner’s character-processing loop to track
whether it is inside a string literal, including escaped quotes, and exclude
literal contents from postulate detection. Preserve the existing nested-comment
and line-comment handling outside strings so valid string text cannot trigger
the Agda gate.
- Around line 15-16: Update the file-discovery flow around `mapfile` so failures
from `find` are detected and cause the scan to exit non-zero, rather than being
masked by process substitution or `sort`. Preserve the sorted file list and
existing empty-file handling.
- Line 29: Update the `two == "--"` check in the scanner’s comment-only control
to recognise Agda line comments when text immediately follows the opener, so
`--postulate postulate` is ignored; preserve the existing handling of whitespace
and end-of-line cases.
- Line 15: Update the file discovery used by `mapfile` and `find` to follow
symlinked `.agda` modules, including targets outside the scan roots, or
explicitly fail when such links are encountered; do not silently omit them and
report a complete scan. Preserve the existing filename filtering and sorting.

Review on #170 (Codex, CodeRabbit), each finding checked:
- The cone is now the module set `agda --dependency-graph` reports for the
three roots, resolved to files on the include path and in Agda's own
library; an unresolved module fails the gate. The directory scan both
missed the 8 prover-supplied modules and swept in unimported ones.
- First-party modules (6) must have no postulate. Agda.Primitive's
universe-level primitives (Level, lzero, lsuc, _⊔_, bound by BUILTIN)
are reported as the prover's trusted base; a postulate in any other
prover-supplied module fails.
- The scanner takes explicit files, refuses unreadable ones, and lexes
`--` comments with no space, and string and character literals.
- Controls must exit exactly 0 and 1, and the planted one must be named.
- Run 42076969251 predates the changed gate, so it is recorded as the
last receipt for the modules; the first green run of this gate on main
replaces it.
- The stale "23 TESTED" is gone; Rust guidance names Creusot/Pearlite and
Verus throughout.
Verified locally: gate OK (6 first-party, 0 postulates; 2 BUILTIN blocks
in Agda.Primitive); a never-reporting scanner, a comment-blind scanner and
a planted postulate in Epistemic.agda each fail the gate.

…y name
The scanner treated only space and tab as keyword boundaries, so a postulate
next to NO-BREAK SPACE, a Unicode space separator, CR, FF or VT went
unreported. Agda reads every isSpace character other than tab and newline as
a space (Agda.Syntax.Parser.Alex, toASCII); the scanner now does the same,
byte-wise in the C locale so mawk and gawk agree. The planted control gains a
NO-BREAK SPACE case, and the comments-only control `--postulate postulate`.
The prover-supplied allowance was the path Agda/Primitive.agda. The gate now
requires those blocks to declare exactly Level, lzero, lsuc and _⊔_, each with
its BUILTIN binding, so a prover pin that adds a postulate fails.
PROOF-NEEDS states the PWG-3 grade as pending its re-run receipt, and
PROOF-GRADES cites the green branch run of the changed gate as evidence.

…gda does
A block comment was removed without leaving a token boundary, so
`postulate{- c -}X : Set`, which Agda reads as a postulate, became
`postulateX` and was not reported; in Agda.Primitive it would also have slipped
past the name check. A comment now leaves a space behind.
A pragma was scanned as code, so a FOREIGN payload using `postulate` as a
Haskell name failed the gate, and a payload holding `{- {-` opened a comment
Agda never sees, hiding a postulate after the pragma. Agda does not nest
comments inside a pragma and closes it at a `#-}` token (Lexer.x); the scan
now skips to the first `#-}`, which can end a pragma early but never late.
Controls: the comments-only file gains a FOREIGN payload; the planted file
gains the comment-separated and after-pragma cases, and must name lines 2-5.

Recognize line comments after character literals
When a line comment immediately follows a character literal, such as c = 'x'-- postulate X : Set, Agda consumes the apostrophe-delimited literal and then lexes -- ... as a comment, but this condition examines the raw preceding apostrophe, treats it as a name character, and leaves the comment text in code. The subsequent regex therefore reports a nonexistent postulate and fails the gate for a valid dependency; determine the comment boundary from the normalized token stream or reset it after skipping the literal. The separate character-literal and line-comment rules are visible in the Agda 2.6.4.3 lexer.
The reason will be displayed to describe this comment to others. Learn more.
Confirmed. This arrived after #170 merged, so the fix is in #174. prev is now the last character emitted as code, so a skipped literal, comment or pragma leaves a token boundary. c = 'x'-- postulate … exits 0, and the comments-only control carries that case. The scanner at 9ff3043 fails exactly this case among 32, under both mawk and gawk.
#170 now records its gate change as "PWG-3, receipt pending re-run".
The comment edits here are covered by the same first green run on main.

The import cone Agda reports includes modules supplied with the prover,
and Agda.Primitive declares the universe-level primitives by postulate
(accepted by --safe through BUILTIN bindings). §8.4 said nothing about
them, so every Agda receipt either omitted them or allowed them by file
name. Proposed rule: they are the prover's trusted base, admissible only
when the receipt lists each by name with its binding and the gate checks
that exact list; any other prover-supplied postulate fails, and a change
to the list (e.g. a pin bump) re-earns the receipt. §8.2 adds the field.
Proposal for owner ruling; reference implementation hyperpolymath/januskey#170.

…-3 split (#171)
## What
This was stacked on #170, which is now merged; it
now targets `main`. No previously proved statement is weakened. One
statement is generalised: T-2 and T-3 move from the transaction model to
an abstract log.
**1. Ledger repairs.**
- #168's T-8 TESTED rows and its T-9 OPEN row were lost on `main`; they
are restored. T-9's artefact is `operations.rs`.
- E-1m gets its status-table row.
- The comments in `TransactionAtomicity.agda` and `Reversibility.agda`
no longer describe since-fixed bugs or imply a derived grade.
- E-1m's rotation states its `old ≠ new` premise.
**2. PWG census and leg records (PROOF-POLICY §8.4.7, §8.5).**
- Census: denominator 5. G-3 is outside it: it names this repository's
FFI bridge, which makes it engineering under §1.
- Per-leg records for every theory row. A leg nobody has started is
recorded as "not attempted", not `unavailable`.
**3. T-1 recheck legs: `PWG-2ii` (PROOF-POLICY §2).**
- Transport is unavailable. Agda2Dedukti was last changed in January
2022, builds against a forked Agda branch, and cannot read modules
checked by Agda 2.6.4.3.
- Both legs are therefore re-proved by hand in core Rocq 8.18 and core
Lean 4.35.0, with no Mathlib.
- Each leg reports no axioms.
- The §2.2 statement comparison and the residual logic differences are
recorded in `docs/theory/PROOF-GRADES.adoc`.
- Rocq and Lean twins of `ForwardRollback` pin non-vacuity.
- `scripts/check-recheck.sh` fails on any axiom, on an accepted fixture,
and on a fixture refused for another reason. Mutants with `Admitted` and
`sorry` are caught.
- New CI job: `agda-proofs.yml` → "Rocq and Lean recheck legs".
- Rocq: `coq=8.18.0+dfsg-1build2` on `ubuntu-24.04`.
- Lean: 4.35.0, checked by SHA-256.
- It sits in the same workflow, so `actions.lock` is unchanged.
**4. T-2/T-3 split (owner ruling).**
- `SingleActiveLog.agda` (new, builtins only) proves the invariant for
any record type with a decidable key and an active or settled phase.
This is theory. `finish-good` needs only the settling law.
- `TransactionAtomicity` Part B is now januskey's instance. Every cited
theorem name is kept.
- New engineering row T-10 (OPEN): the Rust TransactionManager refines
the abstract log, for Creusot or Verus.
- `tests/reject-agda/SettleWithoutSettling.agda` pins the settling
premise: it is refused with `1 != 0`, and its true counterpart checks.
Census after this PR: `PWG-3` 4 (G-1, T-2, T-3, E-1m) · `PWG-2ii` 1
(T-1) · `PWG-2i` 0 · `PWG-1` 0 · `ungraded` 0.
## Verification (local)
- Agda gate (2.6.4.3): four roots, cone 7 first-party files, 0
postulates; all 7 fixtures refused as named.
- Recheck gate (Rocq 8.18.0, Lean 4.35.0): both legs closed, both
fixtures refused as named.
- Idris2 0.8.0 typecheck of the ABI package passes.
- `dashboard-check`: OK.
- Aspect tests: 32 pass.
- shellcheck: clean.
## Not in this PR
- Rocq and Lean legs for G-1, T-2, T-3 and E-1m.
- T-10.
- The dashboard job's Agda 2.6.3 pin.
- Open Codex P2 on #170's scanner (it fails closed after a character
literal).
- The owner-run Actions-allowlist widening for the seven standards
callers.

…rry forward only what is new
#170 and #171 landed the PWG records, the import-cone postulate scan, the
restored T-8/T-9 rows and the T-1 recheck legs while #172 was in review. In
every overlapping file this merge takes main's version, and it removes #172's
scripts/agda-cone.sh, which duplicated scripts/scan-postulates.sh. What #172
still adds on top of main:
- T-12 (TESTED): TransactionManager::new refuses a log read from disk that
breaks Good, and the unused active_mut is removed. T-10 (the refinement
itself) stays OPEN; T-12 is evidence for it at the load boundary.
- Dashboard: Agda 2.6.4.3 from agda-proofs.yml's pinned image. #171 listed
this as left undone. The "two pins" obligation is marked resolved.
- Owner decisions of 2026-11-09, recorded on T-5 (the directory fsync stays
best-effort) and T-9 (to be closed with a write-ahead intent log).
- E-1m: a note that adversary-ignorant and obliterate-ignorance are proved
for two particular worlds.
- Test count 143.

…main's Agda gate
Codex found this on #172. main's scripts/check-agda.sh (#170) writes Agda's
dependency graphs under `mktemp -d`. The Agda wrapper mounted only $PWD, so
the graphs were written into the container's private /tmp and lost. The gate
then reads Agda.Primitive and the other prover modules on the host, at the
path `agda --print-agda-dir` reports, and that path existed only inside the
image.
The wrapper now also mounts $TMPDIR (default /tmp). The setup step copies
the image's lib/prim to the same path on the runner and checks that
Agda/Primitive.agda arrived.
Reproduced locally before the fix, with a stand-in image whose data dir
exists only inside the container: "Reversibility.dot: withBinaryFile: does
not exist". After the fix, running the workflow's own setup step and then
check-agda.sh through the generated wrapper gives: import cone of 7
first-party modules and 8 prover-supplied; both scan controls behave; all
seven fixtures refused as named; [check-agda] OK.

*"Recognize line comments after character literals"*.
The scanner decided whether `--` (or `'`) starts a token from the
**raw** character before it. In `c = 'x'-- postulate X : Set` the
closing quote of the character literal therefore counted as a name
character, so the line comment was not recognised, and a postulate Agda
never sees failed the gate. That is a false failure, so it fails safe,
but it is still wrong lexing. The scanner now uses the last character it
**emitted as code**. A skipped literal, comment or pragma leaves a
space, just as it leaves a token boundary in Agda.
## Changes
- `scripts/scan-postulates.sh`: `prev` is the last character of `code`,
not `substr(line, i-1, 1)`.
- `scripts/check-agda.sh`: the comments-only control gains `c = 'x'--
postulate after a character literal`, which must exit 0.
The branch merges `main` into #170's head rather than rewriting it, so
its diff against `main` is exactly these two files (+4/−2).
## Testing
| Check | Result |
|---|---|
| Scanner cases (32), under mawk and gawk | all pass. The scanner at
`9ff3043` (merged) fails exactly the reported case; string literals,
block comments and primed names (`x'--y` stays one name) are unchanged |
| `bash scripts/check-agda.sh` (local Agda 2.6.3) | `[check-agda] OK`:
cone 6 + 8, 0 postulates, Primitive names and bindings checked, controls
behave, 6 rejections refused as named |
| `shellcheck` on both scripts | clean |
## After merge
The first green `agda-proofs.yml` run on `main` at this PR's merge
commit becomes the gate's receipt. #170's merge run 42633520061 at
`05ade78` was green too, but this PR changes the checker again. A
doc-only PR then records that run in `PROOF-GRADES.adoc` and
`PROOF-NEEDS.adoc`, marks 42076969251 `superseded`, and drops "pending
re-run". A doc-only commit changes neither the modules nor the checker,
so it leaves that receipt current.

…file (§8.5.1) (#1450)
**A proposal for an owner ruling, in two parts.** It changes normative
text in `3-practice/PROOF-POLICY.adoc` §8 and adds a deed profile, so it
should not merge without your decision. The two parts are one design:
the §8.4 trusted base is a field of the §8.5.1 receipt.
## Part 1: §8.4, prover-supplied postulates in the cone (`63d4b36`)
### The gap
§8.4 makes the Agda axiom check three parts: `--safe`, a comment-aware
postulate scan of the import cone, and the recorded cone. It says
nothing about the **modules supplied with the prover**. The cone Agda
reports includes `Agda.Primitive`, which declares the universe-level
primitives **by `postulate`**; `--safe` accepts them through `BUILTIN`
bindings. So every Agda receipt in the estate has to do one of three
things with them:
- **Omit them.** The cone is incomplete.
- **Fail on them.** Nothing can be graded.
- **Allow them by file name.** A pin bump can slip a new axiom through,
as Codex showed on hyperpolymath/januskey#170.
### The rule
A prover-supplied postulate is the **prover's trusted base**, not an
axiom of the development. It is admissible only when:
1. the receipt lists it **by name, with its binding**;
2. the gate checks **that exact list**;
3. no other prover-supplied postulate appears.
A change to the list means the receipt must be earned again. The
reference implementation is januskey#170: CI is green at the pinned
2.6.4.3, and against the real 2.6.4.3 `Agda.Primitive` six mutations
each fail the gate while the unmodified file passes.
## Part 2: §8.5.1, the machine-readable proof receipt (`d4b0656`)
### The gap
§8.5 lists what a grade record holds, but no format. secret-types has a
receipt deed of its own, januskey has prose tables, and lintel has none.
So mathesis cannot *derive* grades, which §2.2 and §8.5 require of it.
### The profile
A praxis deed with `:profile proof-receipt`, conventionally
`verification/receipts/*_praxis.deed`:
- **Top-level fields:** `:repository OWNER/REPO` and `:source-commit`,
the full 40-character commit.
- **`(trusted-base (primitive :prover :module :name :binding) …)`:** the
Part 1 list.
- **`(claim :id :pwg :foundation-diverse (leg …) …)`:**
- each leg has `:prover`, `:route` (`source` for Agda; `transported`,
`re-proved`, `waived` or `unavailable` for the rest), the §5 `:token`
and the §2.2 `:state`;
- each leg holds `(receipt :run :commit :checker :invocation :state
[:reason])` records.
### Grades are derived, not asserted, and the reader enforces it
`readProofReceipt` in `1-formats/deed/tools/deed_lint.js` (CLI:
`--proof-receipt-json`) follows the existing Mustfile-profile pattern.
It **recomputes** each claim's PWG from the legs under §8.2:
- **`PWG-3`:** the Agda leg is `proven` or `proven-with-postulates`,
`AGDA-VERIFIED`, with a current receipt whose invocation carries the
§2.1 flags.
- **`PWG-2i` / `PWG-2ii`:** plus one or two Rocq/Lean legs that are
`transported` or `re-proved`, kernel-accepted, `RECONCILED`, and have a
current receipt.
- **`PWG-1`:** `PWG-2ii`, and every counted leg's current receipt is at
the source commit.
It recomputes the §8.3 foundation-diversity tag the same way. It
**refuses** a receipt whose recorded `:pwg` or `:foundation-diverse`
differs from the derived value. The vocabularies are closed, and
malformed input fails closed with no JSON.
## Alternatives considered
| Arm | Elegance and correctness | Dependability | Note |
|---|---|---|---|
| **This PR: profile in standards, derived grade** (recommended, and the
arm you chose) | One canonical reader; the grade cannot be overstated
past it | Tested (130 pass); fails closed | A v0.2 praxis-deed question
in the deed spec's terms: fields beyond the three required, here scoped
to one named profile |
| Adopt secret-types' shape as de facto | Fast | The format is defined
by one repo's script | Not canon |
| Per-repo adapters in mathesis | No format change | Brittle; prose is
not a receipt | |
| Ledger-only grades | Simplest | Grades asserted, not derived |
Contradicts §8.4 |
## Testing
| Check | Result |
|---|---|
| `bun test 1-formats/deed/tools/` | **130 pass, 0 fail**, including 7
new proof-receipt tests: each grade derived and accepted, each
overstatement refused (`PWG-2i` with no recheck leg, `PWG-1` across
commits, a missing §2.1 flag, `BRIDGE-PENDING`, `argued`),
foundation-diversity both ways, and 17 malformed shapes |
| `deed_lint.js --self-test`, `--fixtures`, `--egress-fixtures` (as
`deed-conformance.yml` runs them) | OK, OK, OK |
| `deed_lint.js` on the worked example
`fixtures/proof-receipt/example_praxis.deed` | grammar OK;
`--proof-receipt-json` derives `PWG-3` |
| `asciidoctor --failure-level WARN` on PROOF-POLICY and the tools
README | clean |
## Beyond this repository (after a ruling)
Receipt producers move to the profile: secret-types' `grade-receipt.sh`,
januskey (from its prose tables), and lintel (new). mathesis's census
then reads `verification/receipts/*_praxis.deed` through this reader and
renders a PWG census with its denominator. I'll prepare those PRs
against this branch's reader, and they stay drafts until this is ruled.

…pin across CI (#172)
## Scope after merging `main`
While this PR was in review, #170 and #171 landed most of its original
content, more thoroughly in places:
- the PWG records and per-leg records;
- the import-cone postulate scan (`scripts/scan-postulates.sh`);
- the restored T-8 and T-9 rows;
- the T-1 Rocq and Lean legs (`PWG-2ii`);
- the T-2/T-3 split into `SingleActiveLog`.
The merge commit takes `main`'s version of every overlapping file and
removes this PR's duplicate `scripts/agda-cone.sh`. Four things remain,
on top of `main`.
### 1. T-12 (TESTED): a loaded log satisfies the invariant `Good`
T-2 and T-3 take `Good` as a premise. Before this change,
`TransactionManager::new` loaded any log that parsed, so a hand-edited
or foreign log could start the Rust outside the invariant. A public,
unused `active_mut` could also change a transaction outside the four
transitions.
- **Change:** a log that breaks `Good` is now refused with
`MetadataCorrupted`, and `active_mut` is removed.
- **Tests:**
- `a_loaded_log_that_breaks_the_invariant_is_refused` covers five ways
of breaking `Good`: a pointer to a missing transaction, a pointer to a
settled one, an Active transaction with no pointer, two Active
transactions, and a settled first transaction with the active id.
- `a_log_the_manager_wrote_loads_back` covers idle and busy logs as the
positive control.
- Three mutants each fail the first test: no check at load, last-with-id
instead of first, and no stray-Active scan. Each mutant was confirmed
applied with `cmp`.
- **Ledger:** this is evidence for T-10 at the load boundary. The
refinement itself, T-10, stays OPEN for Creusot or Verus.
### 2. One Agda version across CI (owner decision 2026-11-09)
#170 and #171 both listed this as not done. `dashboard-check.yml` used
to install Ubuntu's Agda 2.6.3. The job now runs on the host, and `agda`
and `idris2` on PATH are wrappers around the images the proof jobs
already pin:
- `debian:trixie-slim@sha256:a29215f6…` with `agda-bin=2.6.4.3-1+b2`;
- `idris2-pack@sha256:f0758996…`.
It asserts `Agda version 2.6.4.3` exactly as `agda-proofs.yml` does.
Agda runs as the runner user. idris2 runs as root, because its toolchain
is under `/root`, and the wrapper hands back any root-owned file it
leaves, so `check-idris-reject.sh` can still delete its scratch copy.
The "two pins" obligation in `PROOF-GRADES.adoc` and `STATE.a2ml` is
marked resolved. On the pre-merge head 59f1d15 this job ran green, with
every Idris2 and Agda row proven through the wrappers.
### 3. Owner decisions recorded (2026-11-09)
- **T-5:** the directory fsync after the rename stays best-effort.
- **T-9:** to be closed with a write-ahead intent log. Not built yet;
still OPEN.
### 4. Design-review note
E-1m's `adversary-ignorant` and `obliterate-ignorance` are proved for
two particular worlds. The general form is `different-store-unknown`.
The other two findings from the review were already on `main`:
`wrap-unwrap-𝟙` and `rotate-forgets-old` hold by definition.
The test count is now 143.
## Verification (local, on the merged tree)
- `cargo fmt --check` and `clippy -D warnings`: clean.
- `cargo test --workspace --locked`: 143 pass.
- Aspect tests: 32 pass.
- `scripts/check-agda.sh`: OK.
- `dashboard-check`: the only divergences are the 10 Idris2 rows,
because `idris2` isn't installed in this sandbox. CI runs them.
