ci: re-pin standards callers to metadatastician/standards@a797d30; record the proof audit; propose crypto-shredding (ADR-0002) - #167
⛔ Blocked on an owner settings action: this PR cannot go green by itself
On every head so far, five standards callers end in startup_failure with zero jobs: CodeQL, Governance, Hypatia, Rust CI and Secret Scanner. Everything else passes, including Dashboard Check, Agda proofs, Idris ABI, E2E, Squabble and the SonarCloud Quality Gate.
Most likely cause (strong hypothesis, not verified): januskey's live Actions allowlist does not yet admit the transferred standards repository.
The canonical list on standards main already carries metadatastician/standards/.github/workflows/*@* (#1365, #1367).
The per-repo widening is done by scripts/widen-actions-allowlist.sh and needs repository Administration rights.
This session's proxy refuses every actions/permissions path, so I could neither read nor change januskey's live list.
cicd-squabbler recorded the same class, B-ALLOWLIST, and is green on this pin.
Hypatia still fails at startup after its secret became an explicit named pass, which rules secrets out as the remaining cause.
To unblock, run this from a metadatastician/standards checkout, with an admin token:
scripts/widen-actions-allowlist.sh hyperpolymath/januskey # dry run
scripts/widen-actions-allowlist.sh hyperpolymath/januskey --apply
Then re-run the five failed workflows.
If they still show zero jobs after that, the next suspect is the lock record shape. The official generator also lists the nested metadatastician/standards@d55304a edge and haskell-actions/setup, and the estate relock tool omits both for callers that don't call ci-pipeline.yml.
secrets: inherit is refused from a user account into an organisation. hypatia-scan, mirror and scorecard now pass exactly the secrets their reusables declare. This cleared SonarCloud.
S-2 is narrowed: the content store's write is atomic by construction only.
Proof-statement audit, recorded in the ledger (faefe32)
ADR-0002, obliteration by crypto-shredding (proposed; nothing built) (967edb8 … bc701e4)
The proposal. Per-blob AES-256-GCM keys live in one key table plus an append-only key journal. Each message is sealed under its own HKDF subkey of the epoch key. There are two roots:
a stable Argon2id store root, from which the HMAC index key is derived;
a keyring-held epoch secret, replaced on every final shred.
A final shred:
opens the table;
folds in the journal;
drops the entry;
re-seals the table under a fresh epoch;
drops the old epoch secret.
Review corrections. Five Codex review rounds corrected:
the pending versus final shred distinction;
scope limited to content-store copies (neither the working file nor pre-migration plaintext on the medium is covered);
migration of ContentHash references and of legacy obliteration records;
the key hierarchy;
AEAD key usage;
benchmark realism.
benches/crypto_shred.rs, measured on random payloads, one run on a virtual disk (read as shape, not absolute numbers):
Against jk's default (gzip) store, the proposed path is within run-to-run noise at 4 and 64 KiB, and adds about 8% at 1 MiB and 12% at 16 MiB.
gzip on incompressible input dominates today's store: 525 ms against 40 ms at 16 MiB. This is a separate finding (E6).
A pending (batched) shred, which appends a journal tombstone, takes 0.20 ms.
A final shred (open, drop, re-seal) takes 0.96, 2.9 and 26 ms at 1k, 10k and 100k keys. One file per key takes 1.2 s at 1k keys and is rejected.
Earlier figures were withdrawn as the benchmark was corrected; §3 records which and why.
Decisions left for acceptance:
where the epoch secret lives, and whether that keyring's deletion is real erasure;
final versus batched shreds;
redacting versus retaining legacy obliteration hashes;
… relock
hyperpolymath/standards was transferred to metadatastician (same repo_id
1116521501, new owner_id 297579217); the API now answers 301. Since then
the seven callers pinned at metadatastician/standards@a85aa8e end before any
job exists (failure/startup_failure, zero jobs, labelled by file path).
Re-point codeql, governance, hypatia-scan, mirror, rust-ci, scorecard and
secret-scanner at metadatastician/standards@a797d308 (standards main
#1394), the pin cicd-squabbler's main went green on (eeec5ed, 2026-11-04).
actions.lock was regenerated by the estate tool, not by hand:
scripts/relock-standards-pin.sh --to a797d308… (standards main 087f6bf)
which rewrote the per-workflow edges, replaced the standards record with
owner_id 297579217, and copied the two new leaf records it needs
(actions/download-artifact v8.0.2, swatinem/rust-cache v2.9.3) from
standards' own lock at the target.
Validated locally: check-lock-sync.sh passes. check-lock-pin-contract.sh
reports the same 11 tag-keyed leaf records as main (pre-existing, not
gated here) and accepts the new caller-side standards edge.

Updated the shared workflows used for security scanning, governance, CI, repository mirroring and project analysis.
Documentation
Updated proof-status documentation to distinguish tested results from open or unverified claims.
Added an audit report and a proposal describing a possible approach to data erasure; the proposal does not represent implemented functionality.
Seven GitHub Actions jobs now use reusable workflows from metadatastician/standards. The proof ledger and audit report record tested content-store claims and open proof gaps. An unaccepted ADR proposes crypto-shredding, with a benchmark target for comparing storage and erasure operations.
The seven jobs now reference workflows from metadatastician/standards at the new pinned commit. Hypatia and mirror replace inherited secrets with explicit mappings. Scorecard removes inherited secrets. CodeQL keeps the same language inputs.
Proof audit and claims
Layer / File(s)
Summary
Record audit findings and assessments docs/reports/audit/proof-statement-audit-2026-10-27.adoc
The report records probe results and assesses content-store integrity, transaction persistence, attestation-chain coverage, key derivation, obliteration, reversibility, and related proof claims. It distinguishes fixed findings from open findings.
Update proof statuses and claims PROOF-NEEDS.adoc
The ledger adds tested content-store claims and open audit-log integrity and obliteration-proof claims. It qualifies the attestation-chain claim and removes an aggregate open claim about proving all six security obligations.
The unaccepted ADR describes a proposed key hierarchy, sealed blobs, recovery and migration constraints, proof assumptions, and planned experiments. It states that the design is not implemented beyond the benchmark.
A Criterion target compares content-store writes and sealing with overwrite, journal, key-table, journal-folding, and per-key rewrapping operations at specified payload and table sizes.

Merge Risk: Low · previous review b6fb5
This PR re-pins workflow callers and adds documentation, an unaccepted design proposal and benchmarks, with no runtime implementation. Before relying on the crypto-shredding design, fix the rotation durability steps in the ADR and correct the proof-ledger claims that go beyond what was tested or verified in CI. The mirror workflow's explicit secret mapping should also be checked against the repository's R2 backup settings.

Adds docs/reports/audit/proof-statement-audit-2026-10-27.adoc: which
"What Needs Proving" obligations are provable as written, which needed a
code change first, and the probe evidence (P0 control, P1-P6) behind each
verdict. A status preamble records what has since been fixed.
Ledger rows, in both tables:
- S-1, S-2 TESTED: content-store path confinement and atomic, repairing
writes (fixed in #163; the four unit tests that pin them).
- L-1, L-2 OPEN: the attestation log does not detect edits to uncovered
fields or to the last entry (P1, P2), nor tail truncation (P3).
- O-1 OPEN: ObliterationProof hard-codes storage_cleared and verifies for
content never stored (P6).
The attestation and content-store obligations now point at those rows.
dashboard-check run locally: every TESTED row (the new S rows included)
and the count checks pass; the PROVEN rows were not run here (no idris2 or
agda in this container) and are left to the Dashboard Check workflow.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
The new owner changes the cross-repository relationship for callers using secrets: inherit, including mirror, hypatia, and scorecard. Inheritance may be restricted when the called repository is outside the caller's organization or enterprise.
The mirror workflow may fail to start or lack the credential needed to update mirrors.
This can occur when: The caller previously met the applicable inheritance restriction with hyperpolymath but metadatastician is outside the permitted boundary.

…rk behind it
ADR-0002 (status: proposed, nothing built) replaces the 3-pass overwrite,
which cannot reach old bytes on SSDs, copy-on-write file systems,
journals or snapshots, with per-blob random AES-256-GCM keys: erasing a
blob is erasing its 32-byte key. It states where the key hierarchy must
end (one root secret held where erasure is real), what becomes provable
(O-1 restated as a finite-map lemma shaped like E-1m), the costs to
reversibility (undo needs the store key), and four experiments to run
before building, the decisive one a forensic scan of a btrfs loop image.
benches/crypto_shred.rs measures the real store and obliterate_file
against a prototype seal and key drop (one run, virtual disk, shape not
absolute numbers): dropping a key costs ~0.74 ms whatever the blob size,
overwriting a 16 MiB blob ~123 ms; sealing doubles store time at 16 MiB
and is in the fsync noise below 64 KiB; a single key table is O(N) per
shred (14 ms at 100k keys), so per-blob key files are proposed instead.
cargo fmt --check and cargo clippy --benches -D warnings pass.

…; narrow S-2
GitHub permits `secrets: inherit` only within one organisation or
enterprise. The re-pin moved the callee from the hyperpolymath user
account to the metadatastician organisation, so hypatia-scan, mirror
and scorecard now pass exactly the secrets their reusables declare:
HYPATIA_SCAN_PAT; the seven optional mirror keys; none for scorecard.
cicd-squabbler already dropped every `inherit` for the same reason.
This is also what SonarCloud flagged (hypatia-scan.yml:32,
mirror.yml:18, scorecard.yml:21: the C security rating on new code).
S-2 claimed the store's write is atomic, but no test injects a mid-write
failure; it is atomic by construction only. The row and the obligation
text now say so, and claim only what the two tests show: a damaged blob
is repaired and no temporary file is left.
Checked: actionlint 1.7.7 (checksum-verified) on all seven callers,
check-lock-sync.sh, YAML parse of the three edited callers, and
dashboard-check (TESTED rows and counts pass; PROVEN rows need
idris2/agda, absent here).

… the store cost
Four review findings on the proposal, all correct:
- Removing a key file is not erasure: a snapshot or CoW extent can keep
it, still wrapped under the live epoch key. A shred is now "pending"
until the epoch it was wrapped under is rotated away, and O-1 is
restated over that rotation; per-shred versus batched rotation is left
as an acceptance decision.
- The guarantee covers content-store copies only. The working file was
plaintext on the medium before jk saw it; E4 gains a product-flow case
that is expected to find the marker, so the limit stays tested.
- HMAC addresses would orphan every ContentHash in the operation log.
Migration now versions ContentHash, rewrites the log in one atomic
save, and shreds the SHA-addressed copies only after that commits.
- The sealed-store benchmark omitted the key file's own synced write.
Re-measured with it: a sealed 4 KiB store is ~1.7x the plaintext one
(2.69 vs 1.61 ms), not "in the noise"; the cost is fsync count.
cargo fmt --check and clippy --benches -D warnings pass.

Claude-Session: https://claude.ai/code/session_013CuBToxr5h9catptGiTsFX
… old records
Three more review findings, all correct, and two change the design:
- A final shred must re-seal every live key under a fresh epoch key.
Measured: one sealed key table costs 1.2 / 3.9 / 34 ms at 1k / 10k /
100k keys (one synced write); one file per key costs 1.2 s at 1k
keys. Key storage therefore flips to the single sealed table, and the
"166x" comparison of a pending key drop against today's overwrite is
withdrawn.
- jk compresses by default, and the benchmark had compression off with
compressible payloads. It now uses random (incompressible) payloads
and measures the default store and compress-then-seal: sealing adds
~1.7x at 4 KiB (the key's fsync) and ~7% at 16 MiB, where gzip on
incompressible input is the dominant cost today (545 vs 40 ms).
- obliterations.json keeps the SHA-256 address of content already
erased, so migration cannot rewrite it. The ADR now proposes redacting
hash, nonce and commitment from legacy records, as a decision for
acceptance.
E5 now covers the full final shred; E6 measures compressible payloads
and skipping gzip when it does not pay. fmt and clippy --benches pass.

…p migration open
Fourth review round, three findings, all correct:
- The benchmark still wrote a key file per blob though §2 had moved to
one sealed table, and rewriting that table on every store would cost
O(live keys). Stores now append one sealed entry to a key journal and
sync it; shreds fold the journal into the table they rewrite anyway.
Re-measured against the default (gzip) store: within run-to-run noise
at 4 and 64 KiB, +8% at 1 MiB, +12% at 16 MiB. The earlier "1.7x at
4 KiB" measured the rejected per-file layout and is withdrawn.
- The HMAC index key had no protection scheme. It is now derived from
the §4 root with HKDF under its own label, never written down, stable
for the store's lifetime, and only as strong as that root.
- Migration exposure does not end when the log rewrite commits: the
old SHA-addressed blobs are plaintext under predictable names until
shredded. Migration stays marked incomplete and resumes cleanup on
every invocation until the last old copy is gone.
fmt and clippy --benches -D warnings pass.

… costs
Fifth review round, six findings, all correct:
- Two roots: a stable Argon2id store root (index key via HKDF, never
rotated) and a random keyring-held epoch secret replaced on every
final shred (epoch key = HKDF over the store root, salted with it).
Rotation no longer re-addresses blobs, and the passphrase alone does
not reopen a retained table.
- One message per AEAD key now holds for epoch-level messages too: the
table and each journal entry get their own HKDF subkey by sequence
number. X-1 is split into AEAD, erasure and KDF assumptions.
- Migration cleanup removes only reachable files; plaintext written
before migration may persist in CoW extents, flash, snapshots and
backups. jk status reports that permanently; a fresh sealed store is
recommended where exposure matters.
- Benchmark: the pending shred is now a journal tombstone (0.20 ms), not
the rejected per-file delete; the final shred times the whole open,
drop and re-seal on 64-byte plaintext rows (0.96 / 2.91 / 26.2 ms at
1k / 10k / 100k keys), replacing reseal-only figures on 92-byte rows.
fmt and clippy --benches -D warnings pass.

Claude-Session: https://claude.ai/code/session_013CuBToxr5h9catptGiTsFX
…old, valid E4
Sixth review round, three findings, all correct:
- Rotation could strand the live table: the keyring and the file system
cannot be updated atomically. Tables and epoch secrets now carry a
generation; a shred adds secret n+1, writes keys.<n+1>, renames a
`current` pointer, then removes secret n and the old files. Open
recovers a mid-rotation store to exactly one openable generation, and
E5 now injects a crash after each step.
- Folding the journal is never zero in practice (the victim's own store
leaves an entry). Measured: 0.42 / 0.45 / 0.77 / 3.44 ms for 10 / 100 /
1k / 10k entries; the final-shred cost is now stated as O(live keys +
journal entries), and the earlier "zero" claim is withdrawn.
- E4 runs with compression off in both arms and requires a positive
pre-shred control, so a gzip-hidden marker cannot pass as erasure.
fmt and clippy --benches -D warnings pass.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_013CuBToxr5h9catptGiTsFX
A store appending under generation n after a concurrent shred folded
that journal, but before secret n was removed, would leave its blob key
in no table under a destroyed secret: permanent loss of undo content.
Every journal append and every whole rotation now holds one exclusive
store lock, and journal entries carry their generation so a store that
waited across a rotation re-seals under the new one. Stricter than the
transaction log's out-of-scope stance on concurrent writers (T-5),
because the failure here is key loss, not a lost update.

… fix TESTED count
Seventh review round, five findings, all correct:
- PROOF-NEEDS: the proof-grade section still said 23 TESTED rows; the
ledger now has 27 (the four S-1/S-2 rows). Corrected.
- The generation pointer is now written by temp, fsync, rename and a
directory fsync before secret n is removed, and recovery picks the
generation that actually opens rather than trusting `current`.
- retrieve and undo hold the store lock shared for the whole use of a
key, so a reader cannot finish an undo after a final shred reported
the content gone.
- A store syncs its journal entry before renaming the sealed blob into
place, and dedupe accepts an existing blob only if its key exists:
a crash can leave a key without a blob, never a blob without a key.
- The journal-fold benchmark now derives every subkey (HKDF expand,
one HMAC-SHA-256 block) inside the timed loop: 0.45 / 0.70 / 2.28 /
18.0 ms for 10 / 100 / 1k / 10k entries, replacing figures that used
pre-derived keys.
fmt and clippy --benches -D warnings pass.

CodeRabbit review findings, verified:
- The Grade 3 receipt (run 40867211509 at 4afb710) predates
Epistemic.agda and --cubical-compatible: its check-agda.sh checked only
Reversibility and TransactionAtomicity, so it never covered E-1m. The
receipt is now run 41687715055 at fc188c4, which ran the current gate
(all three modules, --safe --without-K --cubical-compatible, Agda
2.6.4.3, resource-algebra cf9235c); gate, modules, sibling fetch and
workflow are byte-identical from fc188c4 to this head.
- S-2: store ignores the remove_file error on its write and rename
failure paths, so only a successful store is shown to leave no
temporary file. Both rows now say so.
- ADR-0002: the new generation's files and their directory are synced
before the pointer switch; the journal-fold row is labelled as the
read-and-clear part, the merge being inside the table re-seal.

…ew round
mirror-reusable.yml at a797d30 declares ten optional secrets; the named
mapping that replaced `secrets: inherit` forwarded only the seven forge
keys, so an enabled R2 bundle backup would silently receive empty
credentials. R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY and R2_AGE_RECIPIENT
are now passed too. Every other caller's mapping was re-checked against
its reusable's declared secrets with a YAML parser: all match.
ADR-0002, four findings, all correct:
- Dedupe accepts an existing blob only if it authenticates under the
mapped key; a key's mere presence is not enough after a repair crash.
- Rotation recovery guarantees at least one openable generation (both
are, by design, between the table write and the pointer switch),
selects the committed one, and ends with exactly one; E5 checks that.
- Per-message subkeys use a random 256-bit salt carried in the message,
not a sequence number, which a torn-append recovery could reuse.
- The fold benchmark reads the salted journal from disk inside the
timed loop: 0.48 / 0.74 / 2.43 / 19.1 ms for 10 / 100 / 1k / 10k.
actionlint, fmt and clippy --benches -D warnings pass.

…ecord open questions
Ninth review round, five findings, all correct, and the pattern is now
clear: each prose fix to the key-table, journal and rotation protocol
exposes the next edge. Prose review cannot close that class; a model
can. The ADR now states, as a precondition for acceptance, that the
protocol be written as a state machine and checked for crash
consistency (TLA+ or the Agda kernel beside T-1..T-3), with the four
properties it must hold.
New §9 records what remains open rather than patching it in prose:
duplicate journal keys after a key-first crash; metadata-only
new_content_hash references that migration cannot re-address; locked,
zeroized in-process keys and tables before a shred is final (AV-2);
and the benchmark exclusions. §3 now labels the table row as excluding
the table read, and the table+journal sum as overcounting one
directory fsync.
The two benchmark entry points gain doc comments.

…round-ten questions
Two corrections to text that was wrong as written:
- The acceptance precondition's invariant "no blob without an openable
key" contradicts shredding itself (a shredded blob has none). It now
reads: every live blob has an openable key and every shredded blob
has none.
- §3 compared the measured table-reseal portion (26 ms) with the full
16 MiB overwrite (124 ms) as if it were the complete shred. It now
says the figures do not establish that a complete shred beats
overwriting at any size, and leaves that to E5.
Recorded in §9 rather than patched into prose: never re-seal under a
pending key on retry; the migration marker must be durably written
before any migration mutation; and two benchmark baselines that are not
like for like (flat vs two-level blob layout; obliterate_file's extra
read-and-hash versus the manager path).

// an empty journal. Merging the rows is in the table row.
Measure journal rows in the table reseal
When the journal contains newly stored live keys, these decrypted rows must be appended to the next table and encrypted and written with it. However, fold_journal only builds rows and discards it, while final_open_drop_reseal_table always reseals only the original table minus one row. Consequently, adding the reported benchmark rows omits the reseal and write cost of up to journal_len * TABLE_ROW bytes—for example, all 10,000 rows in the largest journal case—so the documented final-shred increment is understated. Feed these rows into the timed table reseal or benchmark the combined operation.
*** So a migrated store is never reported as unexposed. `jk status` reports "plaintext from before migration may persist on the medium, its snapshots and backups", permanently, for any store that ever held plaintext blobs.
Preserve legacy-exposure state after cleanup
Once migration finishes, §6 removes the incomplete-migration marker, but this permanent warning still requires jk status to distinguish a migrated store from one created sealed. After old references are rewritten and the proposed default redacts legacy records, those stores need not retain any other observable distinction, so a later invocation has no state from which to produce this warning. Persist a separate, durable ever_contained_plaintext flag that is set before migration and never removed; the resumable migration marker can then still be cleared on completion.
For the 1,000-key comparison, every key file is written in the same directory, but write_synced performs a directory fsync inside every loop iteration. A crash-durable batch can fsync each temporary file, rename all 1,000 files, and then fsync their common directory once, just as §2 batches the table and journal publications. This benchmark therefore charges 999 unnecessary directory fsyncs, which can dominate its reported 1.2 seconds and does not support the conclusion that the per-key layout is unworkable. Use a write helper that defers the directory sync until all renames complete.
