feat(verification): derive proof-ledger statuses from CI receipts; fail on over- and underclaim - #1034
This is the fourth and last PR of the proof-ledger stack: #1029 → #1030 → #1031 → this.
The owner ruled on 2026-11-09 that ledger statuses are computed from receipts, and that CI fails both ways on a disagreement.
lane on every row. It names the CI job whose receipt decides the row's status. check enforces the pairing of lane, checker and status.
Proof lanes idris2 and agda give proven.
Test lanes verdicts, tlc and exunit give tested-only.
none covers only argued and open rows.
scripts/proof-ledger.sh gains three commands:
receipt writes one JCS line per checked file.
derive LANES checks each row against this run's receipts.
A stronger status is an OVERCLAIM and a weaker one an UNDERCLAIM; both fail.
TLC's receipt must reproduce the row's bounds (distinct states and depth).
A graded theory row must carry the counted legs its grade claims.
A checked proof file with no row is a warning.
ipkg-files resolves an ipkg's modules to paths.
scripts/proof-ledger-ci.sh runs a checker, records pass or fail receipts, and keeps the checker's exit status. It handles ipkg, verdicts, tlc and exunit.
verify-proofs:
The Idris2, Agda and TLC jobs write receipts and end with a derive step (if: always()).
tla2tools.jar is pinned to v1.7.4 (TLC 2.19, rev 5a47802) with a verified SHA-256. CI used to fetch releases/latest under a cache key named v1.8.0, and that tag is actually a rolling nightly: its jar reports TLC 2026.11.06.
ci.yml: the exunit rows' test files, read from the ledger, now run on every PR and derive. Before this, retraction_test.exs and dispatch_manifest_test.exs ran only inside the full integration suite.
No new actions, so actions.lock is untouched. Derivation happens inside each job, so no artifact passes between jobs.
How has this been verified?
These are local runs with Idris2 0.7.0, Agda 2.8.0.2 and TLC v1.7.4, all built or fetched as CI does:
all 28 rows agree; one warning: verify/src/Verify/Fuel.idr is a totality helper with no obligation
agda
LogtalkMigration.agda under the §2.1 invocation
all 1 row agree
tlc
KinGate — 444715 distinct states, depth 13
all 1 row agree
exunit
stand-in mix (hex.pm is unreachable here): exit 0, then exit 1
3/3 agree; then 3 OVERCLAIM errors, as intended
Contracts:tests/proof-ledger-test.sh has 28 passed, 0 failed (up from 19). The new ones cover:
an all-pass run agreeing;
a failing proof, a missing receipt and unreproduced TLC bounds, each as an overclaim;
an open row whose file checks, as an underclaim;
a PWG above 3 with no counted leg;
a missing receipts file;
two lane-consistency checks.
Lint and gates:shellcheck is clean on all three scripts. actionlint reports nothing new on either workflow; the only note is the pre-existing SC2005. check / render --check / claims / check-proof-status all pass.
Notes
ExUnit outside CI: the exunit lane is real in CI (ci.yml). I could not run mix test here, but Integration Tests runs those same files green on main (c639c46).
When ci.yml runs: it triggers only on PRs into main/develop. So on this stacked PR it runs once the stack is rebased onto main.
…e rendered from it
README-EXPLAINME section 5 requires a proof ledger with one row per
obligation and a closed status vocabulary. Where a machine ledger exists,
it is canonical and the table is derived from it. Hypatia's PROOF-STATUS
was a set of hand-written tables, and those had drifted from estate
policy.
What this adds:
- verification/proof-ledger.jsonl: 42 rows, one I-JSON/JCS object per
line. Each row records kind (engineering|theory), obligation, status,
checker, file and names, axioms, bounds and trust_boundary. Theory
rows also record pwg, foundation_diverse and legs (PROOF-POLICY 8.5).
- scripts/proof-ledger.sh:
- `check` enforces the vocabulary, the status rules and the byte
profile, and checks every named identifier against the tree. The
status rules are: proven carries no axioms; proven-with-postulates
names its axioms; tested-only gives bounds; a PWG appears only on a
theory row, needs the PROOF-POLICY 2.1 Agda invocation, and above
PWG-3 needs a counted leg.
- `render` emits the table and a census line (counts, never a
percentage). `render --check` and `render --write` keep the
PROOF-STATUS block current.
- tests/proof-ledger-test.sh: 15 contracts, each planting a defect the
check exists to catch.
- verify-proofs: the PROOF-STATUS currency job also runs the three steps
above.
Corrections the receipts forced, re-run locally at c639c46:
- Lean 4.30.0, lake build plus Lean.collectAxioms: 44 of the 114 theorems
rest on propext, or on propext and Quot.sound. RateLimiting,
BayesianUpdate, ParserTotality and the ESN preconditions are therefore
proven-with-postulates, with the axioms named. The PageRank
preconditions use no axioms and are proven.
- TLC 2.19: KinGate is a bounded model check, so it is tested-only with
its bounds. Those bounds are 444715 distinct states at depth 13. The
old row's "1,778,860 distinct states" was TLC's temporal-graph total
across 4 branches.
- Agda 2.8.0.2 under --safe --without-K --cubical-compatible: the
LogtalkMigration source digest still matches. It is proven, at PWG-3,
with both recheck legs owed.
- PageRank convergence and the ESN echo-state property are theory. Each
is an open, ungraded row: Agda statement first, no Mathlib.
- New rows record the model-to-runtime link and VCL query correctness,
both open. The Coverage Map, which marked models "Full" without that
evidence, is retired.
- COMPLETE and PARTIAL are gone. "Grade 3" is now written PWG-3.

…me uses
lib/neural/echo_state_network.ex scales the reservoir to an induced
infinity-norm of @reservoir_norm = 0.95. It does not compute the spectral
radius, so the obligation is stated in those terms. Both open theory rows
also name constructive reals as the Agda route, which is the owner's
choice.

…ledger; Agda-first convergence plan
Second PR of the proof-ledger stack (owner decisions 2026-11-09).
- EXPLAINME.adoc moves back to the repository root, as README-EXPLAINME
requires. Every claim in it was re-checked against the tree.
- Removed: "Idris2 proofs verify recipe correctness"; "Haskell Liquid
types"; a nonexistent proofs/agda/ row.
- Corrected: 5 networks is now 8; 7 Zig exports is now 18.
- Volatile metrics give way to the mix tasks that compute them.
- The safety systems are now described as built but not wired.
- It gains [[proof-ledger]], which cites the canonical ledger.
- README's own overclaims are recorded under Known gaps; fixing them is
a follow-up.
- README's proof bullet now describes what is proved, over models not the
runtime, and quotes the ledger census. AFFIRMATION drops "blocked only on
Mathlib network access" (PROOF-POLICY forbids Mathlib) and fixes a dead
.md link.
- scripts/proof-ledger.sh claims: every census README, AFFIRMATION or
EXPLAINME quotes must equal the ledger's computed census. It runs in CI,
with 4 contracts built from the ledger itself.
- The neural-convergence handover is rewritten: Agda first (2.8.0.2,
--safe --without-K --cubical-compatible) over constructive Bishop reals
built on agda-stdlib v2.3 (8326c74), milestones M0-M5, no Mathlib. The
stdlib feasibility was spiked locally under the profile. The ESN is
framed in the induced infinity-norm the runtime actually uses.
- docs/proofs/needs.adoc becomes a pointer to the ledger; its own list had
drifted ("Agda retired", Mathlib).

…dger rows now proven
Third PR of the proof-ledger stack. The owner decided (2026-11-09) to
re-home the Lean engineering proofs now rather than record their kernel
axioms as necessary. That is PROOF-POLICY section 3: interface and
engineering statements live in Idris2.
- verification/proofs/idris2/ gains RateLimiting, BayesianUpdate,
ParserTotality, PageRankInvariants and ESNSpectralScaling, theorem for
theorem, with the Lean names in camelCase. All are under
`%default total`, with no believe_me, assert_total or holes.
- Four of the Lean files had rested on propext, or on propext and
Quot.sound, per Lean.collectAxioms. Idris2 has neither. Their ledger
rows (now rate-limiting, bayesian-update, parser-totality,
pagerank-preconditions and esn-preconditions) are proven. The census
moves from 18 to 22 proven of 42, with 0 proven-with-postulates.
- verification/proofs/lean4/ is removed. The `lake build` job becomes
`Lean hole re-check (HYP-01 control)`: the pinned Lean stays, only for
the verdict fixture. That job is not a required check.
- README, AFFIRMATION, EXPLAINME, PROOF-STATUS and needs.adoc describe the
move. The `claims` gate caught all four stale census quotes before they
were updated.
- tests/proof-ledger-test.sh: the axiom contracts target rows that exist,
and `mutate` now fails when its target row is missing. A vanished row
would otherwise make a contract pass for the wrong reason.
Local receipt, Idris2 0.7.0 built from source with Chez:
- all 12 verification/proofs/idris2/*.idr pass idris2 --check;
- the hypatia-abi and hypatia-verify ipkgs build (exit 0);
- check-verdicts passes (2 positive controls, 5 expected rejections);
- check-trusted-base is OK.

…il on over- and underclaim
Fourth PR of the proof-ledger stack. The owner ruled (2026-11-09) that
the ledger's statuses are computed from receipts, and that a
disagreement fails in both directions.
- Every ledger row gains `lane`, the CI job whose receipt decides it:
idris2, agda (proof lanes, giving proven), verdicts, tlc, exunit (test
lanes, giving tested-only), or none (argued and open rows only).
`check` enforces the pairing of lane with checker and status.
- scripts/proof-ledger.sh:
- `receipt` writes one JCS line per checked file to $PROOF_RECEIPTS.
- `derive LANES` requires each row in those lanes to say exactly what
this run's receipts make it. Stronger is an OVERCLAIM; weaker is an
UNDERCLAIM. TLC's receipt must reproduce the row's bounds (distinct
states and depth). A graded theory row needs the legs its grade
claims. A checked proof file that no row names is a warning.
- `ipkg-files` resolves an ipkg's modules to paths.
- scripts/proof-ledger-ci.sh runs a checker, records pass or fail
receipts, and keeps the checker's exit status. Its modes are ipkg,
verdicts, tlc and exunit.
- verify-proofs:
- the Idris2, Agda and TLC jobs write receipts and end in a `derive`
step (`if: always()`);
- tla2tools.jar is pinned to v1.7.4 (TLC 2.19, rev 5a47802) with a
verified SHA-256. CI used to fetch `releases/latest` under a cache
key named v1.8.0, and that tag is a rolling nightly.
- ci.yml: the exunit rows' test files, read from the ledger, run on every
PR and derive. retraction_test and dispatch_manifest_test used to run
only inside the full integration suite.
- tests/proof-ledger-test.sh grows from 19 to 28 contracts:
- derive: all-pass agrees; a failing proof, a missing receipt and
unreproduced TLC bounds are overclaims; an open row whose file checks
is a stale underclaim; PWG above 3 without a counted leg is refused;
a missing receipts file fails;
- check: two lane-consistency contracts.
Local end-to-end run with Idris2 0.7.0, Agda 2.8.0.2 and TLC v1.7.4:
- derive agrees for idris2+verdicts (28 rows), agda (1 row) and tlc
(1 row: 444715 states, depth 13);
- exunit with a stand-in mix: exit 0 gives all 3 rows agreeing; exit 1
gives 3 OVERCLAIM errors.
The only warning is verify/src/Verify/Fuel.idr, a totality helper with no
obligation of its own.

Summary
Summary by CodeRabbit
Documentation
Added a proof ledger covering 42 obligations, with clearer status reporting and notes on the limits of model-based proofs.
Updated project and verification documentation to reflect engineering proofs in Idris 2, alongside Agda and bounded TLA+ checks.
Added a guide connecting project claims to evidence and outlining known gaps.
Updated TLA+ model-checking results.
Tests
CI now checks the proof ledger and derives proof statuses from recorded results across verification lanes.
The pull request adds a canonical proof ledger, tools to validate it and derive statuses from CI receipts, and CI checks for several proof lanes. It moves five engineering proof models from Lean to Idris2 and updates proof-status material, repository claims and the neural-convergence plan.
Changes: Proof ledger and prover migration
Layer / File(s)
Summary
Ledger validation and status rendering verification/proof-ledger.jsonl, scripts/proof-ledger.sh, tests/proof-ledger-test.sh, verification/PROOF-STATUS.adoc, .reuse/dep5
The JSONL ledger records 42 obligations. The CLI validates rows and referenced files, records receipts, derives statuses, checks census claims and renders the status table. Contract tests cover ledger, receipt and rendering checks.
Idris2 proof models and Lean removal verification/proofs/idris2/*, verification/proofs/lean4/*, verification/PROOF-STATUS.adoc
Idris2 modules model Bayesian updates, ESN scaling preconditions, PageRank invariants, VCL parsing and rate limiting. The corresponding Lean modules and package configuration are removed. The status document records the prover change and model limitations.
CI receipt lanes and derivation .github/workflows/ci.yml, .github/workflows/verify-proofs.yml, scripts/proof-ledger-ci.sh, .machine_readable/testing/blitz.a2ml
CI runs the ExUnit, Idris, Lean-hole, Agda and TLC lanes through receipt recording and status derivation. The TLC tool release is pinned and its digest is checked. The workflow also validates the ledger, rendered table, census claims and ledger contracts.
Proof claims and status documentation AFFIRMATION.adoc, CHANGELOG.adoc, EXPLAINME.adoc, README.adoc, docs/EXPLAINME.adoc, docs/README.adoc, docs/proofs/gap-analysis.adoc, docs/proofs/needs.adoc
Repository proof claims and references now use ledger counts and distinguish model evidence from runtime correspondence. The root EXPLAINME.adoc is added and docs/EXPLAINME.adoc is removed.
Neural-convergence plan and TLC result docs/proofs/HANDOVER-neural-convergence.adoc, verification/proofs/tlaplus/README.adoc
The handover sets out Agda milestones and proof assumptions for PageRank and ESN. It records open runtime-refinement and tanh obligations. The TLC README reports 444,715 distinct states at depth 13 and clarifies the meaning of the 1,778,860 graph-size figure.

…k markers before diffing
CodeRabbit review on #1029.
- check: field types are validated first. A row with a missing or
mistyped field gets only those messages; the later rules would iterate
the wrong type and abort jq, losing every message after it. The
currency pass skips such rows too. A line that is not JSON is named,
and the run stops before the schema pass, which would otherwise crash
with exit 5.
- render --check: when a generated-block marker is missing, it now says
to restore it (exit 2). It used to report a stale block and suggest
render --write, which then refused for the same reason.
- tests/proof-ledger-test.sh: expect_msg asserts the diagnostic as well
as the exit code, so another rule failing first cannot pass a
contract.
- New contracts: missing and extra final LF; a mistyped field (exit
1, its message, no jq crash); a non-JSON line; a missing marker.
- The open-graded contract now asserts its own rule's message.
- 21 passed. Against the previous script, 3 of the new contracts fail.

Reject rows removed from their receipt lane
When a tested row is demoted using the schema-required combination status: "open", lane: "none", and checker: "-", check accepts it, but this selector excludes the row from derive exunit, derive tlc, or derive verdicts. A passing receipt for the same file therefore cannot produce the promised UNDERCLAIM failure; test lanes do not even emit the later UNRECORDED warning. Derivation needs to retain row identity independently of the mutable lane/status fields so that moving an existing checked obligation to none cannot bypass the underclaim gate.
The reason will be displayed to describe this comment to others. Learn more.
Gate the Lean fixture receipt on the Lean re-check
When scripts/check-verdicts.sh succeeds, this lane emits a passing receipt for every tests/accept/*.idr file, including LeanHoleRecheckSound.idr, even though that script explicitly leaves the fresh Lean digest check to scripts/recheck-lean-hole.sh. The latter runs in a separate job and never contributes to this receipt, so derive verdicts reports the verdict-accept-lean-hole row as agreeing even when the Lean re-check required by its obligation, bounds, and checker fails. Run that re-check before issuing this file's pass receipt or incorporate the Lean job's result into the derivation.

…the check's gaps
Codex's review of 748296c found eight gaps. Each is fixed and has a contract
that fails on the previous script (13 new; 34/34 pass):
- Grades: a theory row's grade is now computed from its legs, never trusted.
- Each leg records prover, route, status, correspondence and axioms.
- A leg counts when its kernel accepted it and its statement is
reconciled (PROOF-POLICY 8.2).
- The recorded pwg must equal the computed one, both ways.
- PWG-1 is refused while the ledger records no per-commit receipts.
- +foundation-diverse requires a counted other-foundation leg.
- The asserted `counts` field is gone; no row used it.
- Policy pin: PROOF-POLICY section 7 requires the enforcing gate to cite
repository, path and full commit, and to fail without one. POLICY_PIN names
metadatastician/standards 3-practice/PROOF-POLICY.adoc @ b8f6051. The
rendered block states it.
- Non-object lines: a JSON line that is not an object (`[]`) now stops the
run. It used to vanish from the census while check exited 0.
- JCS profile: a number anywhere is refused. jq -cS equals JCS only without
numbers.
- Control characters: a control character in any string is refused. A
newline could forge a table cell.
- Empty fields: checker, obligation and trust_boundary must be non-empty. An
empty checker on a proven row passed before.
- Markers: render --check needs exactly one BEGIN/END pair, in order. A
second stale block used to pass behind the first.
- Ledger and docs:
- logtalk-migration names all fourteen prevention witnesses its
obligation rests on, not six;
- the TLA+ README gives 444,715 distinct states, the ledger's count, and
explains the older 1,778,860: the liveness graph, 444,715 states across
4 branches.

Merges b2b23e5 (computed grades, PROOF-POLICY pin, check hardening). The
one conflict is in scripts/proof-ledger.sh, where both branches added a
function: claims() here and markers_ok() there. Both are kept.
It also fixes Codex's four findings on 3a483e9:
- `claims`: a claim document that does not exist, or quotes no census, now
fails. It was skipped silently, so a renamed EXPLAINME passed. Two new
contracts; 40/40 pass.
- HANDOVER M3 is stated for a column-sub-stochastic P (each column sums to
at most 1). ||Px||_1 <= ||x||_1 still holds, so the contraction argument
is unchanged, and it covers the matrices the runtime builds:
- dangling nodes give zero columns;
- iterate_trust/4 sums parallel edges into the out-weight but takes one
of them into each target, so repeated outcomes leak mass.
The leak is named as a runtime defect to fix in the runtime.
- HANDOVER: models-runtime-refinement is open and names no evidence;
test/neural_test.exs is a candidate, not that row's recorded evidence.
- EXPLAINME: /api needs a bearer token when HYPATIA_API_BEARER_TOKEN is set
and not empty. Otherwise only loopback clients are answered, unless
HYPATIA_API_ALLOW_NONLOCAL=true.

…bounds; Lean receipt
Fixes Codex's three findings on ba6f713:
- Demoted rows (P1): a row moved to status open, lane none and checker -
dropped out of `derive`, so its passing file could not raise the
promised underclaim. Now:
- a file that passes in a lane where no row names it, while a row with
no lane does, is an UNDERCLAIM. Files shared by several rows
(Verdict.idr, Retraction.idr) are unaffected, because a row in the
receipt's lane names them;
- the exunit step runs every test/*.exs the ledger names, whatever the
row's lane, so the demoted file still yields a receipt;
- UNRECORDED now covers every lane, not only the proof lanes.
- TLC bounds (P2): the state count and depth are parsed from the row's
bounds and compared exactly. `contains` let 44715 stand for 444715.
- Lean fixture (P2): verdict-accept-lean-hole moves to a new `leanhole`
lane. Its receipt is written by the Lean job, through
`proof-ledger-ci.sh leanhole`, only after recheck-lean-hole.sh passes.
That job then runs `derive leanhole`. The Idris acceptance of the fixture
is still the verdicts job's, and fails that job on its own.
`derive` also computes the theory grade from the legs, as `check` does, in
place of the removed `counts` field. It reports a grade above or below what
this run's receipts and legs support.
Contracts:
- 3 new: demoted row, suffix count, failed Lean re-check;
- the first two fail on the previous derive;
- 52/52 pass.

Wrong-lane receipts for a file are silently accepted.
If a passing receipt names a file, and any ledger row names that file in a different non-none lane, the elif ($named | length) > 0 then empty branch suppresses it. An example is the verdicts glob, which includes tests/accept/LeanHoleRecheckSound.idr. That file's row is in lane leanhole, so it is not checked against this receipt. The receipt neither matches a row nor produces a warning.
This does not break the current ledger. It can hide a row that was moved to the wrong lane. Emit a warning (UNRECORDED-style) when a pass receipt matches no row in its own lane and no none row, but matches rows in other lanes.

Update the pass-receipt matching logic so a file with ledger rows only in
different non-`none` lanes emits an `UNRECORDED`-style warning instead of being
silently suppressed. Preserve the existing same-lane match and `none`-lane
`UNDERCLAIM` behaviour, and include the receipt file and lane in the warning.

the text about `%default total` and the checker reads as one continuous sentence
across the wrapped lines.
Review comments at @verification/proofs/idris2/RateLimiting.idr:
- Around line 56-57: Document the boundary difference in the `inWindow`
docstring or the relevant ledger row: the model includes events at
`windowStart`, whereas the deployed limiter excludes events exactly one window
old. Do not change `inWindow` or its proofs unless verifying that
strict-boundary change preserves them.

Complete the sentence in the docstring.
Line 56 says "the checker refuse this" and continues on unchanged lines 57-58. The text is split by the edit. The prose is now disjointed. Reflow the paragraph so it reads as one sentence.

Trivial · Functional Correctness · Low value
The model's window boundary differs from the deployed limiter.
inWindow keeps an event when windowStart <= timestamp. This keeps an event with ts = now - windowSize. The deployed filter in lib/safety/rate_limiter.ex uses now - ts < window. It drops that event.
The proof is correct for the model. The difference is an off-by-one at the boundary. The ledger's trust boundary and the file header already say the model is not shown to match the runtime. They do not name this specific difference. Add one sentence to the docstring or ledger row that names it. Alternatively, change inWindow to windowStart < ts and re-check the proofs.

Summary
This is the fourth and last PR of the proof-ledger stack: #1029 → #1030 → #1031 → this.
The owner ruled on 2026-11-09 that ledger statuses are computed from receipts, and that CI fails both ways on a disagreement.
