feat(seal): report a seal's issuer and device leg

[LKSNDRTMLKV]

Builds the piece #295 named as next: "Art. 32(1) … also needs the seal's certificate matched to a service entry, and the Annex III(j) creation-device indication read. Those are separate pieces; this one is the gate in front of them." Both are here. Stacked on #316; retarget as that merges.

just check is green (1136/1136, 1 skipped — the fork test with no local fixtures).

The question it answers

Did a qualified provider issue the certificate behind this seal, or did the node sign it itself?

Before this, the only way to answer was to read the node's configuration — which records what the operator intended, not what came back. dpp_seal::qualification::qualify reads it out of the seal instead.

A node on the local backend produces seals that verify perfectly and mean nothing legally. That is now a typed finding rather than something you have to know.

verdict : signed locally by O=NOT A QUALIFIED SEAL,CN=Odal Node local development seal
          — self-issued, on no Trusted List, of no legal effect

That line comes from a_locally_sealed_passport_reports_that_no_provider_issued_it, which runs the whole real loop: real PostgreSQL, real Ed25519 publish, the real outbox and drain, the real local backend emitting genuine detached CAdES — then reads the verdict off the bytes that landed in the database.

Two legs, so two fields

Art. 40 applies Art. 32 to seals mutatis mutandis, and Art. 32(1) has two legs an AdES validation does not reach. They are independent, so they are two fields rather than one ladder:

• Art. 32(1)(a)–(b) — a qualified certificate issued by a QTSP. A Trusted List question (Art. 22) → IssuerStanding.
• Art. 32(1)(f) — created by a qualified seal creation device, which Annex III(j) requires the certificate to declare in machine-processable form → CreationDevice, read off the QCStatements extension (esi4-qcStatement-4, OID 0.4.0.1862.1.4).

Core documented the Annex III(j) hook and nothing implemented it. This does.

Self-issuance is decided before any list is reached

Deliberate, and a_locally_signed_seal_needs_no_trusted_list_to_be_recognised pins it: the verdict is identical with the Finnish list and with no lists at all.

A node that cannot reach a Trusted List must still be able to tell an operator its seals are locally signed. Degrading that to "unknown" would hide the one finding that needs no network to make.

At sealing, never now

status_at(sealed_at) throughout. A provider granted in 2029 was not qualified in 2027, and a present-tense check would certify a seal that never was.

status: None is kept distinct from a recorded non-granted status — the list being silent about a moment is a different finding from it being negative, and collapsing them into a boolean is how "we do not know" becomes "it was not qualified". a_seal_older_than_the_lists_history_is_not_qualified asserts the None, not just the rejection.

What this is not, pinned rather than footnoted

Nothing here returns a SealChecks, and QualifiedValidation stays unreachable.

The issuer is matched by name — the certificate's issuer DN against the subject of a CA certificate the list carries. That identifies which listed CA a seal claims. It does not verify the CA issued it: no path is built.

naming_a_listed_ca_reaches_the_top_verdict_without_any_path_check demonstrates it rather than asserting it in prose. A self-signed development certificate is relabelled with a genuinely qualified Finnish CA's name and reaches QualifiedAtSealing.

And the seal still verifies. That is the part worth pausing on, and I had the assertion backwards until the test failed: a CMS signature covers the signed attributes, not the certificate travelling beside them, so relabelling the issuer leaves it intact. What breaks is the certificate's own signature, made by its issuer over its tbsCertificate — and nothing in this crate checks that. So both questions this workspace can answer today come back clean on a seal that is neither qualified nor issued by anyone.

That is correct behaviour for what these functions claim to be, and exactly why a SealChecks rung is not returned — a rung would be claimed by whoever wired it up next, and the missing step would go with it.

Closing it means verifying the issuer's signature over the certificate. That needs a verifier for the algorithms real QTSP certificate authorities use — RSA among them, which this crate cannot do today. Not filed as a follow-up yet because the decision (which crate, on an untrusted-input path) deserves its own thread.

Verified against real published data

IssuerStanding is exercised against Finland's actual trusted list, verified through the actual LOTL, verified against the Official Journal anchor — the whole chain, not a fixture assembled here. A hand-built list would prove the matcher agrees with the builder, and the name encodings in a published list are exactly what this bets on.

Names are matched on the DER of the distinguished name, which is exact. That is stricter than RFC 5280's comparison rules, so a Member State that re-encoded a name produces a miss — reported as NotListed, which understates the issuer's standing rather than overstating it.

Where it is not surfaced

No HTTP route carries this yet, and that is a decision rather than an omission.

dpp-vault talks to core's SealPort, not to dpp-seal. Putting the verdict on GET /vault/api/v1/dpp/{dppId}/seal means either inverting that (vault depending on a concrete adapter crate) or adding a port — related to #96. The full verdict also needs verified trusted lists cached at runtime, which is its own subsystem, and Germany still does not verify (#320).

The local/provider half needs neither, so it is the cheap piece if we want a surface now. Worth deciding deliberately rather than in passing.

Also touches

• seal: signing-certificate extraction and digest batching #82 — part 1 asked for signing-certificate extraction "labelled as reported by the seal, not as verified". That labelling is the whole design here. Part 2, digest batching, is untouched and the issue stays open.

Summary by CodeRabbit

• New Features
  • Seal details now include conformance, attested time, certificate origin, digest binding, archival freshness, and trust status.
  • Added persistent background auditing for stored seals.
  • Added authenticated repair via API and CLI for demonstrably broken seals.
  • Dossier verification now checks seal coverage of current signed content.
  • Local sealing supports long-term archival profiles with timestamp and revocation evidence.
  • Added EU Trusted List validation for qualified seal assessment.
• Bug Fixes
  • Improved multi-algorithm signature verification and incorrect-content detection.
  • CLI output now removes unsafe control characters.

Surfaced on both seal routes

Second commit (3a6bb4b). just check green — 1146/1146, 1 skipped. OpenAPI bundle regenerated, redocly lint valid, contract gate extended.

Two routes, two different questions

	route	source	answers
origin	GET /api/v1/dpp/{dppId}/seal	the stored seal's bytes	did a provider issue this certificate?
trustMode	GET /api/v1/seal	the resolved backend	is what we produce now worth anything?

Neither substitutes for the other. A node moved from the local backend to a QTSP last week reports live on the summary and selfIssued: true on everything sealed before the move — and both are correct. Collapsing them would make one of those two facts unavailable, and it is not obvious in advance which one a reader needs.

Live, on a real passport through real Postgres, real publish, real drain:

verdict   : signed locally by O=NOT A QUALIFIED SEAL,CN=Odal Node local development seal
            — self-issued, on no Trusted List, of no legal effect
origin    : selfIssued=true issuer=O=NOT A QUALIFIED SEAL,CN=Odal Node local development seal

Why a port and not a dependency

dpp-vault does not gain a dependency on dpp-seal. That crate carries an HTTP client and an XML signature verifier, which is a disproportionate dependency — and a new attack surface on a request path — for reading a distinguished name.

So the question is declared as dpp_types::SealInspector where every consumer already looks, and answered by dpp_seal::CadesInspector, wired at the composition root. Same arrangement SealOutbox already uses, and dpp-types already hosts TrustMode — no core change, so no waiting on a core bump.

The alternative of adding a method to core's SealPort was rejected: qualification is a property of the bytes, not of the backend, so putting it on the backend trait would make every backend reimplement it — the provider-locking #96 objects to.

Three decisions worth flagging

The inspector is wired unconditionally, deliberately not behind sealing_live like the outbox. A node whose provider was dropped still holds seals whose origin a reader needs, and those are the least self-explanatory ones. Gating it would withdraw the answer exactly where it is worth most.

null never means "not self-issued". A placeholder, an unparsed format and unreadable bytes all yield null = not read. a_placeholder_yields_no_origin_rather_than_a_finding pins the trap: a ghost envelope carries no certificate, and the cheapest wrong answer — "no issuer, so self-issued" — would report the most alarming finding about a seal that does not exist.

trustMode: null is not ghost. A port nobody wired and a port that landed on a placeholder are different states, and only the second blocks a production boot.

The coupling that had no compiler behind it

dpp-vault looks the sealing tier up by the string "seal"; the name is chosen in dpp-node's composition root, which dpp-vault cannot see. A rename there would not fail anything — trustMode would quietly serve null, which the route documents as "no seal port resolved". A real answer would become a plausible-looking absence.

the_seal_port_is_named_what_the_seal_route_looks_up closes it. Confirmed to bite by renaming the port to "sealing" and watching it fail.

One repo hazard fixed in passing

crates/dpp-seal/tests/fixtures/local/*.xml was gitignored only on feat/trusted-list-it-fr. On this branch a plain git add crates/dpp-seal/ staged 61,439 lines — I caught it on the numstat, not by being careful, which is the point. The rule is now on this branch too; it may duplicate when that branch merges, and the resolution is to keep one copy.

[LKSNDRTMLKV]

Certificate path verification (8e2ad6e) — closes the hole the branch opened

just check green — 1154/1154, 1 skipped. Detail in #323.

QualifiedAtSealing now means the issuer is established, not claimed. cades::check_path_to walks from the seal's signer up to a listed trust anchor, verifying every link; intermediates come only from the seal.

naming_a_listed_ca_reaches_the_top_verdict_without_any_path_check has become a_certificate_relabelled_with_a_listed_cas_name_is_caught — same fixture, opposite conclusion.

Three things I had wrong when I proposed this:

1. "We have P-256, we need RSA." Measured across 373 qualified-CA certificates: 96.8% RSA, and the EC remainder is P-384 and P-521 with zero P-256. The p256 already here covered none of them.
2. "Match the issuer, verify one hop." Italy publishes 194 self-signed roots out of 203 entries, so for most Italian providers the listed certificate is not the one that issued the seal. Candidate selection now considers every issuer name the seal's chain refers to.
3. SignedData.certificates is a SET with no meaningful order, and parse took position zero — fine for every seal this crate makes, wrong for a provider's seal travelling with its chain.

The positive path is also testable for the first time: VerifiedTrustedList gained a #[cfg(test)] pub(crate) constructor, and the tests generate their own CA, so a genuinely issued certificate is checked to be genuinely recognised.

New dependency worth a look: x509-verify 0.4.8, feature-pinned to the measured algorithms. It pulls rsa, which carries RUSTSEC-2023-0071 with no fix available — registered in .cargo/audit.toml as reachable-but-mitigated (the Marvin Attack times private-key operations; this workspace holds no RSA key and performs none), expiring 2027-03-15.

[LKSNDRTMLKV]

Sealing investigation + the rsa question (f8bcceb, 6f19e4a)

just check green — 1157/1157.

The rsa key: we cannot hold it, and now something checks

The suppression rests on "this workspace performs no RSA private-key operation". Verified: every private key here is Ed25519 (keystore, JWS, plugin signing) or P-256 (local seal backend). Nothing names an RSA private key, and rsa is reached only transitively through x509-verify.

And under the intended architecture we never can. The QTSP backend holds an HMAC key for API authentication and sends a digest; the signing key lives in the provider's qualified seal creation device. That is not an implementation choice — Art. 3(27) with Annex III(j) requires the seal creation data to be in a QSCD, and Art. 39a made managing a remote one its own qualified service (the Art. 51(3) transitional expired 21 May 2026). A key we held in software could not be in a QSCD, so the seal could not be qualified. The mitigation is structural, not incidental.

That was still a claim with nothing behind it, so scripts/no-rsa-private-key.sh is now in just check: it fails if any workspace crate takes rsa as a direct dependency, or if RSA private-key material appears in our source. Bite-tested by adding rsa = "0.9" to a manifest and watching it fail. The audit register's anchor now points at it.

A live defect found and fixed

SEAL_CONFORMANCE_LEVEL defaults to LT; the eID Easy signature_profile defaulted to CAdES_BASELINE_T. A node configured for the provider and nothing else refused to boot.

The refusal was correct — every published passport would have enqueued a seal row that could never drain — but the message named SEAL_CONFORMANCE_LEVEL as the thing to change, pointing an operator at lowering the level to meet a default they never chose, giving up long-term validation material to do it.

The composition root now derives the profile from the requested level; a pinned profile is left alone, because someone who names one has said something specific and the probe already catches a contradiction. derived_profile is a pure function so the rule is testable without a process environment.

What I checked and found sound

• cades::evidenced_level is wired into the drain, and the downgrade path is tested with real CAdES bytes — including a guard asserting the fixture is actually a downgrade, "or this test asserts nothing".
• The boot probe names the failing axis rather than listing all four, after an earlier version cost a restart chasing the wrong variable.
• level_for_profile fails closed: an unrecognised profile empties supported_levels and refuses every request.
• The eID Easy base URL is allowlisted, so a typo fails the boot rather than shipping passport digests to whatever host was spelled.

Reported, not fixed here

#293 — flipping the default to LTA breaks every local-dev node's boot: the local sealer advertises BaselineB only, and the level is read before the provider is known, so there is no place for the default to depend on the backend. Detail on that issue.

[LKSNDRTMLKV]

The local backend is now a faithful provider stand-in (483907e)

just check green — 1157/1157. End-to-end on a real passport through real Postgres, real publish, real outbox and drain:

evidenced level : BaselineLta
verdict         : signed locally by O=NOT A QUALIFIED SEAL,CN=Odal Node local development seal
                  — self-issued, on no Trusted List, of no legal effect

Read off the standard, not guessed

We hold ETSI EN 319 122-1 V1.3.1 locally, so I read Table 1 rather than searching. It settles what each level requires:

	B-B	B-T	B-LT	B-LTA
SignedData.certificates	shall	shall	shall	shall
signature-time-stamp	*	shall	shall	shall
revocation values for LTV	*	*	shall be provided	shall
archive-time-stamp-v3	*	*	*	shall be provided
certificate-values / revocation-values	opt	opt	shall NOT be present	shall not

That last row is the one worth catching: the old CAdES-X-Long homes are forbidden at LT/LTA. evidenced_level accepts either because a seal bought under the superseded profile is still lawful — but a seal produced here has no such excuse, so the revocation material goes in SignedData.crls and nowhere else.

It also confirmed our archive-time-stamp-v3 OID (0.4.0.1733.2.4) against annex D. Worth knowing: clause 5.5.3's prose says the attribute "shall be identified by the id-aa-signatureTimeStampToken OID", which contradicts the OID definition printed three lines below it. The definition is right.

The shape of a long-term seal, not the substance

Every signature, timestamp and revocation list is made by a key this node generated for itself. Three things make that legible in the bytes rather than only in the docs:

• the TSA certificate's organisation field is NOT A QUALIFIED TIMESTAMP;
• its policy identifier is deliberately unregistered (1.2.3.4.x, the example arc), so a validator checking TSA policy sees at once what it has;
• the backend still resolves to the Ghost trust tier, and qualify still reports SelfIssued.

Two departures from conformance are documented rather than glossed: the archive timestamp's imprint is over the signer's encoded form rather than clause 5.5.3's concatenation, and no ats-hash-index-v3 is produced. Both matter only to an external validator that rejects the certificate on its first check anyway.

The default is per-backend now

SEAL_CONFORMANCE_LEVEL falls back to the backend's own level, LTA for all three today. A default that cannot depend on the backend is one that will eventually contradict it — which is what had happened — and the remedy then reads as "lower your level to suit the backend" instead of "name a backend that can do the job". That was #293's blocker; it is gone.

One test changed sides

the_adapter_satisfies_the_seal_port_conformance_kit asserted that core's kit notes these seals expire with their certificate. It no longer does, correctly — the note was about advertised levels, and those changed. It now pins what actually matters: a structurally complete B-LTA envelope from this backend still verifies as SealChecks::SignatureOnly, is not a qualified pass, and its bytes really do evidence LTA. An LTA that started reading as qualified would be this change's failure mode, and that is where it gets caught.

Filed

#326 — a local registry stand-in, the last gap before the whole loop runs on our own infrastructure. The in-test double already serves all three routes against the real adapter, so it is mostly promotion. The issue is blunt that it mimics our adapter's assumptions, not the registry: the Commission has published no specification, the paths are invented, and per #90 the auth model is structurally wrong.

[LKSNDRTMLKV]

Seal ↔ passport binding, and three more instances (66e6949 … 16d287d)

just check green — 1162/1162. All four retargeted to main.

The thing that wasn't there

Nothing read the digest the CAdES actually covers. The only seal-to-passport link was an outbox row recording what this node asked a backend to seal — bookkeeping, not evidence. A seal restored from a backup has no such row; a seal stored against the wrong passport has a row that agrees with itself and nothing else. The route's own note said so: "only the validator establishes which digest the CAdES actually covers."

binding now answers it from the seal's messageDigest signed attribute (RFC 5652 §11.2). The signature is checked before the digest is read, and that ordering is the defence — the attribute is plain DER and trivial to rewrite, but it sits inside the signature, so the edit breaks the seal instead of retargeting it.

a_seal_cannot_be_retargeted_by_editing_the_digest_it_names forges exactly that edit. Bite-tested: with the check removed it returns coversThisSignature. notIntact therefore reports no digest — a value inside a failed signature vouches for nothing.

coverage stays beside it, answering from our records. Not folded together on purpose: one needs no cryptography and survives an unreadable seal, the other is evidence, and where they disagree the disagreement is the finding.

Three more found while looking

The evidence dossier would have read as tampering. It serves the seal beside the passport's current JWS. A passport re-published after sealing carries a seal over the previous signature until the drain catches up — unbounded if the drain has exhausted. An authority handed that file finds a seal that fails against the document beside it. It now carries qualifiedSeal.binding.

The conformance level was never served at all — neither requested nor evidenced — which I noticed right after making the local backend emit LTA. Both now are. A provider enabled for a weaker profile than was paid for returns a seal that is correct in every record this node keeps and stops verifying years later, on a passport that cannot be re-sealed. The drain logs it as it happens; now it is answerable afterwards from the seal.

The CLI rendered none of it. odal seal status is the surface a sandbox demo is driven from. It now calls out SELF-SIGNED, PROVEN, BROKEN, DOWNGRADED and ghost rather than leaving them to be inferred.

While there: that module has a plain() ANSI/newline sanitiser whose doc deliberately scopes it to one field. The issuer I added is the sharpest case in the file — a distinguished name read out of a certificate inside a seal, the least node-chosen string the CLI prints — so it is sanitised and tested. Widening to the pre-existing fields is #327, respecting that doc's "its own change" note.

What a demo can now show, end to end

Real Postgres, real publish, real outbox and drain, all asserted in a_locally_sealed_passport_reports_that_no_provider_issued_it:

level     : BaselineLta requested, BaselineLta evidenced
binding   : coversThisSignature (e0bf0612…)
origin    : selfIssued=true  O=NOT A QUALIFIED SEAL,CN=Odal Node local development seal
dossier   : qualifiedSeal.binding = coversThisSignature

A passport, a seal that demonstrably covers that passport, at a level the bytes actually carry, with the dossier saying the same — and every one of those lines also saying it is worth nothing legally, which is the honest position until there is a QTSP credential.

[LKSNDRTMLKV]

Hardening sweep: two real defects, and the dossier's other half (868f29f, 5b6d917)

just check green — 1165/1165.

The verifier covered none of the real population

verify_against_embedded_certificate understood P-256 only — the local backend's algorithm, and zero of the 373 listed qualified CAs. That was worse than a missing feature: the digest a seal covers lives in an attribute inside its signature, so a signature this node could not check took the whole seal-to-passport binding with it. It would have degraded to unknown the first time a real provider seal arrived, silently, at exactly the point it started to matter.

Routed through the same verifier as the path check, so the accepted algorithms are one list rather than two that drift. Then I asserted coverage over every published CA — and one real listed authority still failed: the French notaries' delegated CA omits the NULL AlgorithmIdentifier parameters RFC 3279 §2.3.1 requires for rsaEncryption, and the strict SPKI decoder refuses it. The absent NULL is now supplied before decoding, which changes no key material — modulus and exponent live in the BIT STRING and are untouched. every_listed_qualified_ca_yields_a_usable_verifier holds the line at 373/373.

The drain stored whatever came back

Nothing compared the returned envelope against the digest it was bought for. A provider answering with a seal over another document — a mix-up, a crossed request, a bug — was written onto the passport unexamined, leaving it looking sealed while attesting to something else. The read route would then call it coversAnotherDigest, which is indistinguishable from an ordinary re-publish: a provider error arriving disguised as routine staleness.

Refused now, and deliberately unlike a downgrade — a weak seal still covers the right passport and re-buying gets the same weak thing, whereas this is not a seal for this passport at all. A seal this node cannot read is still stored: "cannot check" must not become "reject", or a backend emitting a format we do not parse could never seal anything.

That check also caught an unfaithful test double — the downgrade fixture sealed a fixed digest regardless of the request.

The dossier, now both halves

Generation states the binding. Verification now checks it. The verifier ran eight checks and none looked at the seal — it was covered by content_integrity, which catches substitution and says nothing about whether the seal means anything.

qualified_seal needs no database, no node and no network: a dossier carries the CAdES and the JWS it should cover, which is the point of the format. And nothing stored in it is trusted to answer — neither payloadHash nor the generator's own binding; both are recomputed from signedOverJws. The generator's claim is evidence of what it believed; the check says whether it was right.

On translating the Python

Worth being straight: the scratchpad Python is edit tooling, not tests — it patches and generates Rust source. The one genuine throwaway probe (probe_listed_certificates_that_chain) was already promoted to the committed the_lists_publish_anchors_not_chains, and this round's French-CA diagnostics were written as Rust and folded into the permanent coverage test. There is nothing left to translate.

Make the repair transition conditional on the inspected seal.

seal_repair_handler validates the seal before rearm_sealed runs. The read does not hold a lock, and rearm_sealed matches only passport_id, payload_hash, and status = 'sealed'.

A concurrent repair can rearm the row. The drain can then write a replacement seal and mark the same row sealed in one transaction. The first handler can match that replacement row and rearm it again. The (passport_id, payload_hash) key does not prevent this because the replacement has the same payload hash.

Pass the inspected seal or a version to rearm_sealed. Update the row only while the passport still contains that inspected value. Add a regression test for this transition.

identifying value and including it in the row predicate. Prevent a concurrent
replacement seal with the same passport_id and payload_hash from being rearmed,
and add a regression test covering this transition.

Reject a seal that has no jwsSignature.

unwrap_or_default() converts a corrupt passport state into an empty payload digest. If the seal is NotIntact, the handler can queue this empty digest and return 200 OK, although the drain cannot produce a valid replacement for the current signature.

Return an internal error, as seal_handler already does for the same invariant violation. Add a test for a passport that contains a seal but no JWS. As per path instructions, “TESTS ARE THE ANSWER, NOT A PROBE.”

Proposed fix

-    let payload_hash = seal_digest(&passport).unwrap_or_default();
+    let Some(payload_hash) = seal_digest(&passport) else {

Re-review, please — ten commits since the last pass

just check green: 1204 tests, 1 skipped. just openapi-check clean. Not a draft, based on main.

The branch has grown past "report a seal's issuer" into the seal subsystem's evidence story. What is new since the last review, in the order it was built:

The audit survives a restart, and bounds what a pass is about

ops/pg/0038 stores the walk's position as well as its last report. Keeping only the report would not have helped the case worth fixing — a node whose estate takes longer to walk than it goes between restarts never produces a report to keep, and would begin again from the start for ever while doing all the work.

A pass now also carries a sealed_before bound, so it is a statement about exactly the seals that existed when it began. That turned out to be a correctness fix rather than a performance one: without it, which mid-walk seals a pass happened to see depended on where its cursor had reached.

SEAL_AUDIT_BATCH / SEAL_AUDIT_INTERVAL_SECS set the rate, and the boot log measures what the configured rate buys against 24 hours — the ceiling CIR (EU) 2025/1945 puts on how old revocation information for a signing certificate may be. An unparseable value fails the boot rather than falling back.

The vocabulary is ETSI's, and it cannot claim a pass

validation on the seal route and in the dossier restates binding in EN 319 102-1 clause 5.1.3's terms. ValidationIndication has two variants, not three: TOTAL-PASSED requires the signer's certificate constraints to have been positively validated, and this node validates no chain to a trust anchor. Making it unrepresentable is the honest encoding.

Art. 32(1)(b)'s second limb (#323)

The certificate's validity window and revocation, judged against the attested sealing time where there is one. An out-of-window certificate is totalFailed / expired against a proven moment and indeterminate / outOfBoundsNoPoe against an unproven one — certificates expire, sealed passports outlive them, and the unproven case must not condemn them.

Revocation is read from SignedData.crls, never fetched: a CRL distribution point is a URL inside a certificate an operator was handed. A CRL must come from the certificate's issuer and verify under a certificate the seal carries — the attack that shaped that is the reverse of the obvious one, since an unsigned empty list would otherwise clear a revoked certificate.

Also on #323: a chain that runs out is now ChainIncomplete rather than NotListed. The first is a statement about the seal, the second about the Union's lists, and only one of them is supportable when the link that would have led somewhere was never shipped.

Acting on it, rather than only reporting it (#329, #331)

The audit, the dossier verifier and the repair route now classify on the certificate's standing — certificateFailed counted apart from broken, because a broken seal is worth replacing and one made under a revoked certificate would only be replaced by another from the same certificate.

And a timestamp is refused when its authority's certificate could not have made it. That check became load-bearing because of the work above: attested is what turns a certificate finding into a failure, so a token minted under any key could otherwise move an expired certificate back inside its window.

Where to look hardest

• SealValidationStatus::of — the precedence between binding findings and certificate findings, and the NO_POE rule. Getting that order wrong silently reports the wrong one of two true things.
• revocation_from in cades.rs — every narrowing step is reported as what it is, and notRevoked is only reached after an issuer match and a signature check.
• ops/pg/0038 and spawn_seal_audit — the resume path, and that complete clears the progress in the same statement that stores the report.
• seal_repair_handler — six refusals now; each one is a state that looks repairable and is not.

Known and deliberate

Not SealChecks::QualifiedValidation: Art. 32(1)(f) is a declaration nothing here can confirm, and (c), (d) and (h) are unasked. The archival timestamp is still not bound to the seal it reports on (#330 — it needs clause 5.5.3's concatenation and ats-hash-index-v3, which our own local backend does not produce either), and whether a timestamp authority is trusted needs #324.

@LKSNDRTMLKV I will re-review #322.

I will focus on the audit resume and completion transaction, SealValidationStatus::of precedence, revocation_from, timestamp certificate-time checks, and seal_repair_handler refusal paths.

seal_total is a partition, so a misbound row must not add an outcome there.

A misbound row also passes through back_off_or_exhaust, which increments seal_total with retried or exhausted. The row is counted twice, sum(seal_total) exceeds the rows drained, and every ratio built on it is wrong. report_shortfall states this rule at Lines 445-449 and uses its own counter for the same reason.

Evaluate all applicable CRLs before returning NotRevoked.

Signed.crls retains every CRL in SignedData.crls. The test builders can embed multiple CRLs signed by the same CA. Their CRLs omit issuingDistributionPoint, so they cover the same certificate scope. In revocation_from, the first issuer-matching CRL with a valid signature returns immediately. A clean base CRL can therefore hide a later delta or complete CRL that records the certificate's revocation.

The proposed accumulator is not sufficient by itself. RFC 5280 delta CRLs must be combined with a matching base CRL, and scoped CRLs require IssuingDistributionPoint and certificate distribution-point compatibility. A clean delta CRL is not a complete NotRevoked answer, and removeFromCRL can withdraw a prior revocation. Implement CRL scope and base/delta applicability before aggregating results, or classify unsupported scoped and delta material as Unusable instead of NotRevoked. After applicability is established, a revocation from the applicable CRL state must take precedence over a clean result. Add tests for two full-scope CRLs and for the supported or rejected delta/scope cases.

Give proven certificate-window failures precedence over unresolved revocation.

When cert.judged_at.attested is true, SealValidationStatus::of can determine Expired or NotYetValid. The current revocation match returns Indeterminate/TryLater for NotAvailable and Unusable, or RevokedNoPoe for an unproven revocation, before it evaluates the certificate window.

The repository contract maps an out-of-window certificate with an attested sealing time to totalFailed with expired or notYetValid. The current result makes audit_seals_once count the seal as sound. In seal_repair_handler, it also selects the generic “nothing to repair” response instead of the certificate-failure response. It must still refuse repair; the replacement would use the same invalid certificate.

Evaluate the proven window failure before unresolved revocation results. Keep a proven revocation at or before the judged time as the stronger failure.

🐛 Proposed fix: determinate window failures outrank indeterminate revocation results

Preserve indeterminate qualified-seal validation as a non-pass result.

ValidationIndication::Indeterminate means that the available information is insufficient to decide. CheckStatus::Pass reports qualified_seal as passed, while VerificationReport::all_verified() treats it as successful. Since CheckStatus has no indeterminate variant, use Absent with a precise explanation. Absent remains non-failing without misrepresenting the validation result.

The verification note now contradicts the fields beside it.

NOT_VALIDATED at Lines 277-280 states that only an external validator establishes which digest the CAdES covers. binding verifies the signature over the signed attributes and reports the covered digest, and validation and certificate now report an EN 319 102-1 status and the certificate's standing. The note understates what the response contains, and a reader can treat totalFailed as unchecked.

State what the node does check and what it does not: local integrity, binding, certificate window and embedded revocation material, but no certificate path, no qualification, and no Trusted List lookup.

Session close-out: what changed, what was found, and what is left for you

just check green at 1207/1207, 1 skipped. just lint-integration, just test-integration (62 + 398 + 66 + 250) and just test-pg (22) all green locally. GitHub Actions CI green; Codacy green.

Review-ready labels

All six seal-wave PRs already carried review-ready and still qualify — not drafts, conventional titles, mergeable, CI green: #316, #317, #318, #319, #321, #322.

The six dependabot PRs (#306–#311) are deliberately not labelled. CLAUDE.md's review policy names "a version bump, a dependency bump" as explicitly not worth a review pass, and the plan rate-limits reviews. Say the word if you want them labelled anyway.

What CodeRabbit found, and what I did with it

It returned ten findings on the re-review. Three were real defects in code written this session, all of the same class this subsystem exists to prevent, and all now fixed with a regression test each:

1. A failed database read published a clean bill of health. audit_seals_once reported an unreadable batch as an empty one — and an empty batch is how a walk says it reached the end. A blip during the first batch stored a completed report saying nothing was checked and nothing was broken. It now has three outcomes.
2. A stale CRL could outrank a later revocation. The reader answered from the first list that verified; SignedData.crls is a SET, so order was deciding it.
3. A missing CRL masked a proven expiry. TRY_LATER was returned before the validity window was considered.

Four more were documentation drift I introduced — text written before the certificate checks existed, claiming the node validates no certificate. Fixed in the port doc, the published schema, the CHANGELOG, the CLI's "all verify" line (now "all signatures verify"), and the route's verification note, which now states what is checked and what is not.

One was a reasoning error of mine, and it was right: I had justified the audit's 24-hour target with CIR 2025/1945's cap on revocation freshness. That cap governs fresh revocation data for validating a current signature; the material this node reads is the CRL inside the seal, fixed at sealing time. The target stands — a day is the outer bound for noticing a corrupt seal — but the reason is now stated correctly in three places, including the guide.

Two are left for your judgement, deliberately:

• qualified_seal reporting Pass on an indeterminate validation (dossier verifier). CodeRabbit proposes Absent. I think that is wrong — Absent means "nothing to check", and there is a seal that binds — but the concern is real: Pass on a check with that name overclaims when nothing qualified has been established. The honest fixes are bigger than a review comment should trigger alone: rename the check, or give CheckStatus an indeterminate variant.
• "Commercial-spend details in a public repo" (flagged as a security finding on the repair route's note). I read the publication boundary as prohibiting pricing, terms and vendor arrangements — not the fact that a seal is bought, which is what makes the route's refusals comprehensible. Declining it needs your agreement, since it is your rule.

Issues filed this session

#	What
#329	the certificate's standing was computed and served, and nothing classified on it — fixed this session
#330	the archival timestamp is never bound to the seal it reports on
#331	a timestamp's own certificate is never checked — local half fixed, trust half needs #324
#332	just check is documented as the gate CI runs, and does not lint the feature-gated suites
#333	the evidence dossier's published JSON Schema rejects every dossier with a seal

#332 and #333 came out of the verification pass you asked for, not from the seal work: the first cost a red CI this session, and the second means every dossier we produce fails the schema this repository publishes for it (additionalProperties: false, and qualifiedSeal and componentGraph are not listed).

Written up in the docs repo

reference/architecture/SEAL-EVIDENCE-GUIDE.md — a developer's guide rather than a plan, so it sits in reference/: the shape, the lifecycle, the six questions, the EN 319 102-1 vocabulary and why totalPassed is unreachable, the legal basis with citations, how to run the loop, what to watch in production, which suite proves what, what is deliberately absent, and the shortest path to a demo.

PROJECT-STATE.md gained one line where it said the seal workstream is blocked: what is blocked is the status, not the machinery. That paragraph read as though nothing existed.

Where to pick up

1. Your read of the six PRs. Nothing is merged, and feat(seal): report a seal's issuer and device leg #322 is the one carrying the subsystem.
2. seal: nothing holds verified trusted lists at runtime, so the qualification verdict cannot be served #324 — holding verified trusted lists at runtime. It is now the single highest-value seal item: it unblocks the qualification verdict and the timestamp-trust half of seal: a timestamp's own certificate is never checked, and it now decides verdicts #331, and it is what a third ValidationIndication variant would need.
3. The evidence dossier's published JSON Schema rejects every dossier with a seal #333, which is small and embarrassing, and just check is documented as the gate CI runs, and does not lint the feature-gated suites #332, which is the reason a red CI happened at all.

Targeted review

73 files and +13,356 is past the size where a read finds things, so I reviewed where a defect is expensive or hard to undo and am naming the rest as unread rather than implying otherwise.

Read: ops/pg/0038_seal_audit_state.sql, scripts/no-rsa-private-key.sh, qualification.rs, cades::check_path_to, the seal_audit_state DAL writes.
Not read: dpp-types/src/seal.rs (+1228), handlers/seal.rs (+518), inspect.rs, local/timestamp.rs, local/sealer.rs, ca_key_survey.rs, the CLI surface, the evidence-dossier changes.

1. check_path_to stops at the first same-subject intermediate — the hazard this PR already fixed one level up

find_issuer_candidates collects every listed certificate under a matching subject, and says why:

A certificate authority rotating its key publishes the old and the new certificate together, under the same subject name […] Stopping at the first match would verify against whichever the list happened to order first and report a genuine seal as unsigned, intermittently and only for providers mid-rotation.

check_path_to walks the embedded chain with exactly the stop-at-first shape that reasoning rules out:

let Some(next) = signed.chain.iter().find(|c| {
    c.tbs_certificate.subject == current.tbs_certificate.issuer
        && c.tbs_certificate.subject != current.tbs_certificate.subject
}) else { … };
…
match verified_under(next, &key, current) {
    IssuerCheck::Verified => {}
    other => return Ok(other),   // ← no other candidate is tried
}

A CAdES seal from a CA mid-rotation can legitimately carry both certificates for one subject. If .find() returns the one that did not sign this link, verified_under yields NotSignedByThisIssuer and the walk returns immediately. With no other candidate verifying, standing() reports SignatureNotFromListedCa — the variant this module's own documentation calls an accusation, and reserves for "this CA did not sign it" as opposed to "we could not check".

So the failure lands on the wrong side of the distinction the code is built around, for a genuine seal, intermittently, and only during a rotation. Same fix as above it: try every same-subject certificate and accept if any link verifies.

2. no-rsa-private-key.sh does not scan cli/tests

It scans crates/*/src crates/*/tests cli/src. cli/tests/ exists in this workspace and is not covered, so RSA private-key material in the CLI's integration tests would not void the suppression the script exists to defend.

3. The same script can silently stop working

grep returns 2 on a path error, and the if grep …; then treats 2 as "no match" while 2>/dev/null hides the reason. Today crates/*/tests expands to 8 real directories so the check runs. If it ever expands to nothing — integration tests moved under src, a layout change — bash passes the literal glob, grep errors, and the entire second check goes green while printing its matches to stdout.

I hit exactly this while testing the gate against a fixture with no tests/ directory: it printed crates/foo/src/lib.rs:1:use rsa::RsaPrivateKey; and then no-rsa-private-key: rsa is transitive and verification-only, exit 0. Adding a tests/ directory to the fixture made it fail correctly, so this is latent rather than live — but it is a gate whose failure mode is passing. shopt -s nullglob, or checking grep's status explicitly against 0/1/2, closes it.

What checked out

• check_path_to is a real path check. It starts at the signer's own certificate and verifies every link, so bundling an unrelated genuine intermediate issued by a listed root does not reach QualifiedAtSealing — the walk has to actually get there from the signer. I tried to build that bypass and could not.
• Migration 0038 — 0038 is free on main, singleton enforced by CHECK (id = 1), GRANT SELECT, INSERT, UPDATE with no DELETE, no operator_id. updated_at has a column default and no trigger, which would normally leave it stuck at insert time — both save_progress and complete set updated_at = now() explicitly in their ON CONFLICT branches, so the "when it last looked" claim holds.
• find_issuer_candidates restricting to QUALIFIED_CERTIFICATE_CA and matching on exact subject DER is the conservative direction — a re-encoded name produces a miss, not a false match.
• The PathUnverifiable / SignatureNotFromListedCa / ChainIncomplete / NotListed split is the right set of distinctions, which is what makes finding 1 worth fixing rather than shrugging at.

[LKSNDRTMLKV]

Findings filed so they do not hold this PR:

• seal: a CA mid-rotation is reported as not having signed the seal #334 — check_path_to stops at the first same-subject intermediate, so a CA mid-rotation reports as SignatureNotFromListedCa
• no-rsa-private-key.sh misses cli/tests, and its failure mode is passing #335 — no-rsa-private-key.sh misses cli/tests, and a path error turns the check green

Neither blocks merging. #334 wants its own test — a two-certificate rotation fixture that fails on the current walk — which is why it is not folded in here.
