feat(auth): add NIP-FI canonical assertion verifier and contracts by wpfleger96 · Pull Request #6776 · block/buzz

The closed, provider-neutral contract layer at the root of the NIP-FI federated-identity dependency graph — Phase A, PR 1 of the plan. It has no dependencies on any other PR and defines no database schema, migration, runtime JWKS fetching, binding resolution, enrollment, or request/proof binding; those belong to later PRs.

What this adds

Multi-issuer assertion-policy config (IssuerRegistry, IssuerPolicy) keyed by exact iss. Identity is issuer-qualified (iss, sub) throughout — equal sub under different iss are distinct identities. The subject coordinate is fixed to the JWT sub claim (SUBJECT_CLAIM), never configurable, so no deployment can seal a mutable attribute like email as identity. Issuer URL and audience remain deployment configuration.
The two deterministic semantic contract identities — AssertionPolicyId = H(canonical assertion-policy contract) and TransportContractId = H(canonical transport contract) — derived by length-prefixed, domain-separated SHA-256 so a semantic change moves exactly its owning ID while benign JWKS rotation never changes policy lineage. Set-valued policy inputs (audiences, algorithms, subject-class values, scope capture) are canonicalized before derivation, so the ID is invariant under permutation and duplication. Config fields that a freshness class never reads are rejected at construction (an offline-jwt policy cannot carry maximum_status_age), so the canonical encoding stays total over valid configs and semantically identical policies always derive one ID.
The single canonical verifier (FederatedAssertionVerifier, FI-INV-16) producing the origin-sealed, provider-neutral VerifiedAssertion normalized result. Its constructor is crate-private, so unverified claims cannot be promoted into authority. The issuer→JWKS authority is entirely crate-owned: AssertionKeySet has no public constructor and IssuerKeySource is sealed, so no downstream crate can relabel one issuer's keys as another's. The authenticated key set is bounded (MAX_JWKS_KEYS) and the bound is folded into AssertionPolicyId, so an unbounded attacker-controlled kid scan cannot be driven; every snapshot requires a finite positive hard deadline.
Sealed revalidation dependencies — RevalidationDependencies carries the key-snapshot hard deadline and a ConfidentialAssertion handle to the exact compact JWS (no Debug/Display/serde leak, sole read path compact_jws()), so a changed snapshot can revalidate the same evidence: a retained key revalidates, a removed key denies.
The privacy-preserving four-class denial contract (DenialClass, FI-INV-13) with the byte-exact Nostr text, HTTP status, body, Content-Type, and WWW-Authenticate values fixed by the spec's rejection table. An unreadable required current dependency maps to authorization_unavailable/503, never to rejected evidence, and rejected evidence never masquerades as a 503 at either end of the pipeline: all bounded, dependency-independent checks (compact structure, header, signature shape, policy, algorithm, token class) precede key-source lookup, and all offline validation (token-class, key, signature, audience, claims, time) completes before any status-witness deferral. A wrong-typ or structurally malformed token, or malformed/invalidly-signed input naming a current-status issuer, therefore denies with evidence_rejected/403 rather than being reported as a 503 availability signal.

Corrections applied to the mined source

Mined from the buzz-auth verifier core in #1476 and corrected to the settled spec (the merged docs/nips/NIP-FI*.md, #5946), which settled after #1476 was written:

Token-class selection with exact typ enforcement. Two classes are offered: at+jwt and nip-fi+jwt. There is deliberately no generic/absent-typ "named compatibility" class: it cannot be proven disjoint from an OIDC ID token by claim presence alone (an issuer can mint an ID token carrying client_id), and the only authenticated discriminator is typ, which such a mode declines to constrain.
OIDC ID-token denial — denies even when iss, aud, and sub match, via exact typ mismatch against every accepted class.
The fixed nostr_pubkey claim accepted only as lowercase hex of exactly one 32-byte key; bech32 and other aliases deny.
Resource-owner / client-subject ambiguity denial and required client_id for at+jwt.
JWK admissibility: a key's use and, when present, key_ops must authorize signature verification (a key restricted to other operations such as encrypt is rejected), and the selected JOSE algorithm is bound to the key's required family and curve (ES256↔EC/P-256, ES384↔EC/P-384, EdDSA↔OKP/Ed25519, RS/PS↔RSA). The JWK alg is advisory; the actual key material is what signs, so a JWK declaring a matching alg over mismatched material (a different family or curve) is rejected before signature verification.
Spec-exact time arithmetic (now < exp, iat <= now + skew, now < iat + maximum_assertion_age, equality at expiry is expired). exp/iat/nbf accept finite integer or fractional RFC 7519 NumericDate values with checked, overflow-safe conversion; non-finite and out-of-range values deny.

Verification

In-crate tests in crates/buzz-auth/src/nip_fi/verifier/tests.rs sign real ES256 assertions against a fixed test key and cover: the happy path, exact-wire-text for all four denial classes, deterministic and semantic contract IDs, canonicalization invariance, token-class enforcement including ID-token denial, JWK key_ops rejection, nostr_pubkey hex handling, time bounds, and multi-issuer selection (same subject across distinct issuers yields distinct identities and policy IDs). They also cover the round-3 contracts: the key-set bound (oversized rejected, at-bound accepted, empty rejected), fixed-sub identity (identity is sub not a configured email; a token without sub denies), offline-before-deferral (invalid-signature, wrong-audience, malformed-claim, and expired under a current-status issuer each deny 403/evidence_rejected), and the revalidation contracts (dependencies carry the deadline and exact JWS; a retained key revalidates, a removed key denies). And the round-4 contracts: algorithm↔key-material binding, covered exactly per accepted algorithm (a table-driven matrix asserts every policy-acceptable algorithm — ES256, ES384, EdDSA, RS256/384/512, PS256/384/512 — matches only its required family/curve and rejects every other, so each mapping mutation fails individually; and an ES256 token against P-384, RSA, and Ed25519 material each deny InvalidKey); malformed evidence classified before key lookup (wrong-typ, two-segment, four-segment, empty-signature, and non-base64url-signature tokens against an empty source deny 403 not 503); maximum_status_age inapplicable under offline-jwt rejected at construction while current-status still requires it; and fractional NumericDate (finite fractional iat/exp/nbf within bounds verify, non-finite and out-of-range deny). Compile-fail doctests guard the sealed authority seam (AssertionKeySet::new, IssuerKeySource) and the absence of the named-compatibility token class.

Notes

Co-authored-by attribution is preserved for the mined author. The feat(relay): add relay-verified identity binding #1476 buzz-auth commits are authored by Cea Stapleton Cordasco (the salvage map records feat(relay): add relay-verified identity binding #1476 under Franco; the git history on that PR is Cea's — surfacing for the attribution/closure record).
Amends docs/nips/NIP-FI.md to remove the "named compatibility access token" class and its FI-TRACE-TOKEN-CLASS oracle reference, so the normative spec matches the two-class root implementation (a generic/absent typ cannot be proven disjoint from an OIDC ID token). Removal-only, no neighbor redesign; a docs/nips/ grep confirms no dangling cross-reference to the class remains.
Adds jsonwebtoken 10.4.0 (aws_lc_rs) as a workspace dependency.

Dependencies: none.

Introduce the closed, provider-neutral contract layer at the root of the NIP-FI federated-identity dependency graph (Phase A, PR 1). This has no dependencies on later PRs and defines no schema, migration, runtime JWKS fetching, binding resolution, or request/proof binding. The module provides: - A multi-issuer assertion-policy registry keyed by exact `(iss, sub)`, with the two deterministic semantic contract identities (`AssertionPolicyId`, `TransportContractId`) derived by length-prefixed domain-separated hashing so benign JWKS rotation never changes policy lineage. - The single `FederatedAssertionVerifier` (`FI-INV-16`) producing the origin-sealed, provider-neutral `VerifiedAssertion` result. - The privacy-preserving four-class denial contract (`FI-INV-13`) with the byte-exact wire text, HTTP status, body, and headers fixed by the spec. Mined from #1476's `buzz-auth` verifier core and corrected to the settled spec (merged NIP-FI docs, #5946): token-class plus `typ` enforcement, OIDC ID-token denial, the fixed lowercase-hex-only `nostr_pubkey` claim, resource-owner/client-subject exclusivity, and spec-exact time arithmetic. Identity is issuer-qualified throughout; no issuer, audience, or claim name is hardcoded — all are deployment configuration.

…ct gaps Address pass-1 review of the NIP-FI verifier/contracts layer. Bind each AssertionKeySet to the exact issuer it authenticates and reject a token whose signed iss does not match the supplied snapshot, closing a cross-issuer authentication bypass under caller misuse. Reject duplicate JOSE/claim members with a duplicate-detecting deserializer so parser- differential ambiguity cannot smuggle a different value past the signature gate. Fold a versioned verifier-contract fingerprint and the normative size bounds into assertion_policy_id and version transport_contract_id, so a semantic change moves its owning ID while JWKS rotation does not. Model resource-owner vs client-subject as a closed, mutually-exclusive SubjectClassContract that denies ambiguous/unclassifiable subjects and gates client-subject eligibility on a recorded non-collision posture. Require the access-token-only client_id claim for named-compatibility policies so they are provably exclusive with OIDC ID tokens. Preserve identity bytes exactly (no trimming). Deny current-status freshness in this verifier until the status-witness runtime lands, rather than sealing without the witness.

The pass-1 fix bound each AssertionKeySet to an issuer and compared that label to the policy at verify time, but verify() still took the snapshot as a caller argument and AssertionKeySet::new is public. A request-path caller could therefore construct issuer B's JWKS labelled issuer A and mint a sealed (A, victim) identity — the cross-issuer key-source confusion was only detected for honest mislabelling, not prevented. Make the key source structural: FederatedAssertionVerifier holds a trusted IssuerKeySource and resolves the snapshot internally by the token's signature-authenticated iss. verify() now takes only the token, so there is no seam through which a caller can supply or relabel key material. A missing snapshot for a registered issuer is an unreadable authoritative dependency (KeySourceUnavailable -> AuthorizationUnavailable), not rejected evidence. A defensive re-check still denies a source that violates its issuer-binding contract. PR 3 supplies a live-refreshing IssuerKeySource additively.

The pass-2 fix moved cross-issuer forgeability off the verify() request seam but left it at the authority-construction seam: AssertionKeySet::new and the IssuerKeySource trait were public, so an external buzz_auth consumer could build a source returning issuer B's JWKS labelled as issuer A, pass it to the public FederatedAssertionVerifier::new, and mint a sealed (A, victim) identity. Make the accepted issuer->JWKS authority entirely crate-owned: - IssuerKeySource gains a private sealed supertrait, so no external crate can implement it. - AssertionKeySet::new becomes pub(crate); a test-utils-gated for_test keeps the crate-owned source usable from integration tests. - A crate-owned, test-utils-gated StaticIssuerKeySource replaces the external MapKeySource the tests defined. compile_fail doctests (compiled as external consumers) prove neither the trait nor the constructor can be named from outside the crate. The verifier's regression suite lived outside 'just test-unit' (which runs buzz-auth --lib only), so it ran in no CI job. Add the integration suite (--features test-utils) and the doctests to the unit-test recipe so the cross-issuer regression and the seal are actually gated by CI.

A downstream-selectable Cargo feature is not an access-control boundary: features are unified and any dependent could enable buzz-auth's test-utils to reach AssertionKeySet::for_test and the StaticIssuerKeySource, reconstruct a relabelled issuer->JWKS authority, and mint a sealed (A, victim) identity from issuer B's real key. Remove for_test entirely, gate StaticIssuerKeySource and its sealed IssuerKeySource impl on cfg(test) only, and move the verifier regression suite into an in-crate #[cfg(test)] mod tests so it reaches the pub(crate)/cfg(test) primitives with zero public feature surface. No supported feature set now exposes an authority-relabelling path; the compile_fail doctests remain as a default-feature seal regression.

Moving the constructor's only callers under cfg(test) left the non-test lib build with no caller, so clippy -D warnings rejected it as dead code (Rust Lint, Windows Rust). PR 3's JWKS runtime is the intended non-test consumer; narrowly allow dead_code on this one item until it lands rather than deferring the constructor or widening the lint. expect would misfire because the lint does not trigger under cfg(test).

The dead_code compile error previously masked this: clippy could not reach empty_line_after_doc_comments until the lib built.

Map the missing current-status witness to authorization_unavailable. verify returns StatusWitnessUnavailable because this phase cannot read the policy's required current-status authority (crates/buzz-auth/src/nip_fi/verifier.rs:276-282), but denial_class maps only KeySourceUnavailable to AuthorizationUnavailable; this error falls through to EvidenceRejected/403 (:458-468). The settled rejection contract assigns an unreadable required current dependency to authorization_unavailable/503 (docs/nips/NIP-FI.md:461-476). Please map this variant accordingly and extend current_status_policy_denies_without_witness to assert the public class and wire response.
Canonicalize set-valued assertion semantics before deriving AssertionPolicyId. Policy construction retains caller order and duplicates (config.rs:182-215, 361-445), while ID derivation hashes that representation directly for audiences, algorithms, subject-class values, and named required/forbidden claims (:605-642). The verifier consumes these as membership sets (verifier.rs:284, 302, 606, 620-621), so permutations or duplicates change the ID without changing accepted assertion semantics. That contradicts H(canonical assertion-policy contract) and the rule that semantic changes move the owning ID (docs/nips/NIP-FI.md:220-238). Please sort and deduplicate these fields before storage/hashing (or reject non-canonical input) and add permutation/duplicate equivalence coverage.

Relatedly, scope capability capture should use the same canonical-set discipline: it currently sorts only by claim name, leaving equal-key values in token order and retaining duplicates (verifier.rs:660-674; assertion.rs:182-197). Thus semantically equivalent scope sets can produce unequal normalized results. Please canonicalize by (name, value), deduplicate, and add parity tests.

All GitHub CI checks are green. This review used read-only GitHub metadata and source/diffs only; PR code was not checked out or executed.

…lass Three review findings on the NIP-FI verifier: - StatusWitnessUnavailable is an unreadable required current dependency, so it now maps to AuthorizationUnavailable/503 rather than falling through to EvidenceRejected/403 (NIP-FI.md rejection table). - Audiences, algorithms, subject-class value sets, and NamedCompatibility claim lists are consumed as membership sets. Sort and deduplicate them before storage and AssertionPolicyId derivation so permutations and duplicates no longer move the policy ID (H(canonical assertion-policy contract)). - Scope capture canonicalizes by (name, value) with duplicates removed so semantically equal scope sets seal byte-equal capabilities. The sealed authority boundary is unchanged. Co-authored-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Will Pfleger <pfleger.will@gmail.com>

Do not treat client_id presence as proof that a named-compatibility JWT is not an OIDC ID token. The normative contract requires named compatibility to be mutually exclusive with every accepted ID-token class and says ID tokens always deny (docs/nips/NIP-FI.md:203-210). Construction accepts any compatibility policy that merely requires a client_id claim (crates/buzz-auth/src/nip_fi/config.rs:431-440), while verification checks only claim-name presence/absence (verifier.rs:623-632). An issuer-produced ID token with generic/absent typ, matching issuer/audience, and an additional client_id can therefore pass. Require and validate an authenticated discriminator whose accepted values are actually disjoint between access and ID tokens, or remove this compatibility mode; add a signed ID-token-shaped regression containing client_id.
Honor JWK key_ops before accepting a verification key. The contract rejects incompatible JWK usage (docs/nips/NIP-FI.md:166-169), but validate_jwk checks only optional use and alg (crates/buzz-auth/src/nip_fi/verifier.rs:695-709) and ignores parsed key_ops. A matching key explicitly restricted to key_ops:["encrypt"] can still verify an assertion and mint a VerifiedAssertion. When key_ops is present, require verify and reject incompatible combinations; add a signed-token regression for a matching kid with key_ops:["encrypt"] expecting InvalidKey / evidence rejected.

This review used read-only GitHub metadata and exact-head source inspection only; PR code was not checked out or executed.

The named-compatibility token class accepted a generic/absent typ=JWT based only on required-claim presence (client_id). Claim presence is not authenticated proof that a token is not an OIDC ID token: an issuer can mint an ID token carrying client_id, and the mode's defining behavior is declining to constrain the one authenticated discriminator (typ). No reliable disjoint discriminator exists for a generic-typ mode in this phase, so the class is removed rather than patched; it had no production construction site. Only at+jwt and nip-fi+jwt classes remain, both gated on exact typ. validate_jwk ignored the parsed JWK key_ops parameter, so a matching key restricted to key_ops:["encrypt"] could still verify an assertion signature. When key_ops is present it must now authorize verify, closing the incompatible-usage gap (NIP-FI.md:166-169).

The generic-typ behavior regression exercises an at+jwt policy, which already rejected generic typ before the mode was removed, so it cannot detect reintroduction of the vulnerable named-compatibility variant. Add a compile-fail doctest on TokenClass that names the removed variant: it fails to compile while the variant is absent and would compile (failing the doctest) if the variant returned.

Changes requested on exact head 6d1e61259ad79b17187b80828a262235fe00fd09 against base c856be0fb954c9e5267d622841098c24e3381e8f.

[P1] Bound authenticated JWKS snapshots before attacker-controlled lookup. AssertionKeySet::new accepts any number of keys (crates/buzz-auth/src/nip_fi/verifier.rs:98-112), then every unauthenticated token naming a configured issuer drives a linear scan by attacker-controlled kid (:248-293, :666-675). A token needs no valid signature to force O(keys) work. This violates the normative requirement to bound the authenticated key set before lookup (docs/nips/NIP-FI.md:166-171). Enforce a key-count bound at snapshot construction, include that semantic bound in AssertionPolicyId, and test that oversized snapshots cannot be installed. The later fetcher must also bound bytes before parsing, but that does not replace this verifier-side invariant. A focused exact-head test constructed and installed 100,000 keys successfully.
[P1] Do not let configuration replace the protocol’s sub identity coordinate. IssuerPolicy::new accepts any subject_claim (config.rs:368-395), and verify seals that claim’s value as FederatedIdentity.subject (verifier.rs:313, :320-324). A policy using email, iss, or another mutable/non-sub claim therefore produces authority labelled (iss, value) even though core defines identity as exact (iss, sub), explicitly excluding email and display name (docs/nips/NIP-FI.md:35-41, :173-175). Make the identity coordinate the fixed JWT sub claim; configurable attributes may be captured separately but cannot become identity. A focused signed-token test at this head configured email, omitted sub, and successfully sealed mutable@example.com as the subject.
[P1] Validate supplied evidence before reporting a missing current-status dependency. verify returns StatusWitnessUnavailable immediately after unverified issuer routing, before token-class, key selection, signature, audience, claim, and time validation (verifier.rs:257-317). Consequently a malformed or invalidly signed token naming a configured current-status issuer receives public authorization_unavailable/503 rather than the required evidence_rejected/403. That contradicts the rejection contract (docs/nips/NIP-FI.md:459-476) and turns invalid attacker input into an availability signal. Complete the offline assertion validation first, then defer only an otherwise-valid assertion for its status witness; add invalid-signature, wrong-audience, and malformed-claim regressions under CurrentStatus.
[P1] Preserve the revalidation material and enforce a finite key-snapshot deadline. The closed result’s RevalidationDependencies retains only kid and generation (assertion.rs:50-69, :173-179), while AssertionKeySet permits hard_deadline: None (verifier.rs:78-112). Core requires the key-snapshot hard deadline and a confidential handle to the exact compact JWS in revalidation_dependencies, so changed snapshots can revalidate the same evidence and removed keys deny (docs/nips/NIP-FI.md:240-249, :371-395). As written, later final admission cannot recover the exact JWS from the claimed canonical result, and a snapshot can be installed with no hard expiry. Add an opaque/confidential exact-assertion handle, carry the key deadline in dependencies, and require a finite positive deadline at snapshot construction; cover retained-key and removed-key revalidation contracts.
[P2] Keep the normative token-class contract synchronized with the closed enum. This head deliberately removes named compatibility and compile-fails external use, while the same repository’s normative NIP still defines that class and its oracle (docs/nips/NIP-FI.md:191-218, :564). The safer resolution is to update the NIP in this PR to remove the class, not restore an unsafe generic-typ fallback. Shipping a protocol contract and implementation that disagree at their root guarantees the next layer will choose whichever one is least convenient.

Verification: exact-head source/contract trace plus focused signed ES256 reproductions for findings 1 and 2; both reproduced, the source was restored, and the worktree is clean. Required product CI is green; the red Mark Previous Review Stale job is the repository-wide advisory workflow-token 403, unrelated to this change. Existing tests do not cover the full boundary/malformed matrix or live consumers, and this phase intentionally has no downstream consumer yet.

Bound the authenticated JWKS snapshot (MAX_JWKS_KEYS) at construction so an attacker-controlled kid cannot drive an unbounded O(keys) scan, and fold the bound into AssertionPolicyId as a semantic input. Hard-code sub as the identity coordinate: remove the configurable subject_claim knob so a mutable attribute (email, display name) can never be sealed as identity. Complete all offline validation before deferring a current-status assertion, so invalid input denies as evidence_rejected (403) rather than authorization_unavailable (503). Require a finite positive key-snapshot hard deadline, and carry it plus a confidential handle to the exact compact JWS (no Debug/Display/serde) in revalidation_dependencies, so a changed snapshot revalidates the same evidence and a removed key denies. Amend NIP-FI.md to remove the named-compatibility token class and its oracle reference, matching the two-class verifier surface.

The F4 rotation test re-verified against the same snapshot and modeled removal as whole-source outage (503), proving same-snapshot reuse and source outage rather than the FI-TRACE-JWKS-ADD/REMOVE contracts, which turn on a changed authenticated generation. Rework it to mint at generation 1 and revalidate the exact carried JWS against two distinct generation-2 snapshots: a retained-key snapshot revalidates (bound to the new generation), and a still-readable replacement-only snapshot denies as rejected evidence (403). Source outage stays covered by registered_issuer_without_key_snapshot_is_unavailable_not_rejected. Also correct two module docs that still claimed all claim names are deployment configuration; sub and nostr_pubkey are now fixed identity coordinates.

[P1] Reject algorithm/key-type and EC-curve mismatches. validate_jwk checks optional use, key_ops, and alg, but never verifies that the JWK parameters match the selected JOSE algorithm (crates/buzz-auth/src/nip_fi/verifier.rs:708-745). A JWK declaring kty=EC, crv=P-384, and alg=ES256, while carrying valid P-256 coordinates, successfully verifies an ES256 token and mints VerifiedAssertion. That violates the normative algorithm/key-mismatch rejection contract (docs/nips/NIP-FI.md:166-171). Bind each accepted algorithm to the required JWK family and parameters, at minimum ES256↔EC/P-256, ES384↔EC/P-384, EdDSA↔OKP/Ed25519, and RSA/PS algorithms↔RSA, then add cross-family and cross-curve regressions.
[P1] Reject safely classifiable malformed evidence before reporting a JWKS outage. verify resolves the key source before policy algorithm/typ enforcement and before validating the exact compact-JWS shape (verifier.rs:269-307). With no snapshot, a configured issuer's typ=JWT token returns KeySourceUnavailable / 503 instead of TokenTypeRejected / 403; a two- or four-segment value likewise reaches the outage result because the early parsers read only the first two segments and exact structure is enforced later by decode. This lets malformed/rejected evidence masquerade as an unreadable authoritative dependency, contrary to the evidence-rejected versus authorization-unavailable contract (docs/nips/NIP-FI.md:151-171, :458-475). Perform all bounded, dependency-independent compact-structure, protected-header, and policy-class checks before key-source lookup, and cover outage × wrong-type/malformed-structure cases.
[P1] Canonicalize or reject the inapplicable status-age field for offline-jwt. IssuerPolicy::new accepts positive maximum_status_age_seconds under FreshnessClass::OfflineJwt (crates/buzz-auth/src/nip_fi/config.rs:385-425) and hashes it unconditionally into AssertionPolicyId (:601-667), although offline verification never reads it (verifier.rs:369-413). A focused reproduction showed None and Some(120) produce different IDs for otherwise identical offline policies. The contract says this ID hashes accepted semantics and that a semantic change moves exactly its owning ID (docs/nips/NIP-FI.md:219-237); an inapplicable representation detail must not create policy lineage or lease invalidation. Prefer rejecting Some(_) for offline policies, or omit it from that class's canonical encoding, with parity coverage.
[P2] Accept finite fractional JWT NumericDate values or explicitly narrow the protocol. numeric_date and optional_numeric_date require serde_json::Value::as_i64 (verifier.rs:763-785), so a signed assertion with finite iat=now-0.5 and exp=now+600.5 returns InvalidTimeBounds. NIP-FI requires finite NumericDate values (docs/nips/NIP-FI.md:173-181), and RFC 7519 defines NumericDate as a JSON number for which non-integer values can be represented. Preserve fractional precision with checked conversion and overflow-safe comparisons, or explicitly make integer-only dates part of the normative assertion contract and its policy identity.

Verification: all four findings reproduced with focused tests at the exact head, after which the worktree was restored clean. The existing buzz-auth package tests passed (94/94) and doctests passed (3/3, 1 ignored) at that same head; git diff --check passed. Required product CI is green. The failed Mark Previous Review Stale and cancelled automated security-review jobs are review-automation/process state, not product-test failures.

…fication, tighten status-age and NumericDate Carl round-4 corrections on the NIP-FI verifier: - Bind each accepted JOSE algorithm to its required JWK family and curve (ES256↔EC/P-256, ES384↔EC/P-384, EdDSA↔OKP/Ed25519, RS/PS↔RSA), so a JWK whose advisory `alg` matches the token but whose material differs cannot verify it. - Run all bounded, dependency-independent checks (compact structure, header, policy, algorithm, token class) before key-source lookup, so rejected evidence is 403 rather than masquerading as a 503 outage. The current-status deferral still fires last. - Reject a `maximum_status_age` under offline-jwt freshness at construction, keeping the canonical policy-ID encoding total over valid configs. - Accept finite fractional RFC 7519 NumericDate values with checked conversion; non-finite and out-of-range values deny.

An empty or non-base64url signature segment previously passed the segment-count structure check and deferred to post-lookup decode, returning 503 during a JWKS outage instead of denying malformed evidence with 403. Add enforce_signature_shape to require a non-empty, well-formed base64url signature before key resolution; cryptographic validity still stays post-lookup. Place it after parse_header so alg=none continues to reject at header parse. Add outage regressions for empty and non-base64url signatures, and a table-driven exact-shape test binding every accepted algorithm to its required key material so each mapping mutation individually fails.

The algorithm-to-key-material matrix only instantiated the four required materials, so it could not prove that an algorithm rejects a family or curve outside that set: nine permissive mutations (ES256/ES384 also accepting EC/P-521, EdDSA accepting any OKP curve, each RS/PS also accepting a symmetric key) all left it green. Add EC/P-521, wrong-curve OKP, and symmetric OctetKey fixtures so each accepted algorithm must reject every non-required shape and each widening mutation fails.

This head resolves the prior exact-head findings: JOSE algorithm-to-key-family/curve binding is exact, bounded dependency-independent structure/header/type checks precede outage deferral, offline-jwt rejects an inapplicable maximum_status_age, and finite fractional JWT NumericDate values are handled safely. End-to-end review found no remaining actionable code, product, security, lifecycle, or compatibility defect. Focused regressions cover the repaired boundaries, and required product CI is green; failing review-automation jobs are non-product process failures.

…6994) PR 2 of the NIP-FI plan: the schema foundation. Establishes the durable server-side identity ledger and final-admission surface that the runtime phases build on. All of Phase A's migrations live here; later phases own their own deltas. Depends on nothing — PR 1 (#6776, merged) owned zero migration files. This PR's relations are shaped to store exactly what PR 1's verifier produces: issuer-qualified identity and the four denial classes. They meet in a later PR that writes a verified assertion into these tables in one transaction. ## Two internally-ordered migrations - `0041_nip_fi_identity_foundation.sql` (migration A) — core identity + base-lifecycle relations (5 tables): issuer-qualified `(iss, sub)` bindings, lifecycle history/selectors, enrollment policies, and operation receipts. Applies cleanly to current `main`. - `0042_nip_fi_authorization_foundation.sql` (migration B) — the final-admission surface (10 tables): authorization events + capacity, admission results, replay/receipt guards, audit, invalidation domains/floors, protected-object authority, authority epochs, and restore version deltas. Applies to A's resulting state. Fifteen NIP-FI relations total, zero dangling foreign keys. Identity is issuer-qualified throughout — no single-global-issuer assumption in any relation, no `Block`-hardcoding. A single deployment may run one issuer; that is config, not schema. ## Durable, immutable ledger posture All 15 relations are append-only (immutable `no_delete`/`no_truncate` triggers) and carry `community_id` as provenance, not ownership. Both migrations widen the single SQL source of truth `community_write_fence_excluded_table` so the relations are never fence-attached, never purged on community deletion, and never counted as tenant-scoped drift by the deletion control plane's exact-set catalog check — the same posture main already applies to `product_feedback` and `rate_limit_violations`. `schema/schema.sql` keeps one consolidated definition of that function whose exclusion array byte-matches `0042`, guarded by a parity assertion so a future consolidation cannot silently drop NIP-FI relations from the ledger. This makes a tenant's identity/authorization ledger survive community deletion, per the spec's `FI-INV-02` (durable binding) and `FI-INV-03` (tombstone monotonicity) and `NIP-FI.md`'s "durable server state" ruling. `communities(id)` FK never dangles: community rows become permanent tombstones, never hard-deleted. ## Authorization shape and cardinality contracts Authenticated `OperatorDenied` events (`actor_kind` 1–3, non-null `request_fingerprint`) carry a null `semantic_fingerprint` and commit without a denial-attempt row. The denial-attempt cardinality and shape guards are scoped to unresolved pre-auth kind-9 events (`actor_kind = 4`). Applied and no-op lifecycle receipts (`outcome_code IN (1, 3)`) require exactly one mapped success-transition event; denied lifecycle receipts (`outcome_code = 2`) require zero events from the complete core lifecycle success-transition class (kinds 1, 2, 3, 6: enrolled, revoked, rotated, retired) — any such event paired with a denied receipt would record a transition that never occurred. ## Mined vs. new Re-cut from Franco's #1476 (`0029`/`0030`) and Cea's #4772 committer schema, re-cut along FK topology and renumbered above the live `main` tip. The buzz-auth core of #1476 is Cea-authored; `Co-authored-by` reflects verified per-commit authorship of the mined schema. Zero Rust/`deletion.rs` edits — the migration-only exclusion widening keeps `EXPECTED_SCOPED_TABLES` untouched. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> Co-authored-by: Cea Stapleton Cordasco <261786559+cea@users.noreply.github.com> Co-authored-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz>

* fix: retrieving cold memories; add regression task (#6950) ## Why Evaluating buzz agent memory retrieval by seeding a memory then asking the buzz agent a question it needs that memory. **Bug Found**: System prompt had no inclusion of retrieving cold memories and suggested looking in a mem/*.md directory that does not exist. Updated `system-prompt.md` to include memory CLI tools and usage. Eval Before System Prompt Change: 0/3 Eval After System Prompt Change: 3/3 ## What - Add a `memory-retrieval` benchmark that seeds agent memory with `buzz mem set` before asking a direct question. - Grade the observable threaded answer without inspecting tool calls or exposing the answer in channel history. - Teach agents to use `buzz mem set`, `buzz mem ls`, and `buzz mem get` for cold memory. - Add a wire-debug endpoint configuration for diagnosing ACP tool calls in local runs. - Add fixture, seeding, verifier, and prompt coverage. ## Risk Assessment Low. The runtime changes are limited to the benchmark harness. The production-facing change clarifies existing memory commands in the base prompt; it does not change memory storage, relay behavior, or authorization. ## References - Before the system-prompt changes, 0/3 attempts passed because agents never invoked the `buzz mem` CLI and instead searched a non existent filesystem - After the changes, 3/3 attempts passed. ACP wire logs confirmed that every agent ran `buzz mem ls` followed by `buzz mem get` and returned `net_gpv`. --------- Signed-off-by: Philip Azar <pazar@squareup.com> * fix(ci): salvage Codex review output on PTY-shutdown hang (#7042) Codex CLI can leave a PTY descendant holding the action's inherited stdio after the turn completes. The `runCodexExec.ts` wrapper waits on a `close` event that never fires, so the `Review pull request` step hangs until the job timeout kills it — discarding the finished review the CLI already wrote to disk. The CLI writes the completed review to the `--output-last-message` file (exposed as `output-file`) **before** the hang. This PR adds a salvage step that recovers it, and sets the step and job timeouts to preserve the full 30-minute Codex execution budget. **Changes (`codex-security-review.yml`):** - Add `output-file: ${{ runner.temp }}/codex-review.json` to the `Review pull request` step so the CLI writes the result before the hang. (`runner` context is valid in `steps.with`; not in `jobs.env`.) - Add `timeout-minutes: 30` and `continue-on-error: true` to the Codex step — a hang now costs ≤30 minutes instead of 40, and the salvage step still runs. - Set job `timeout-minutes: 40` to give setup, step cancellation, and salvage sufficient headroom without colliding with the Codex execution budget. The original 30-minute job timeout was too narrow: evidence from run [33114428326](https://github.com/block/buzz/actions/runs/33114428326/job/98665369165) shows completed output appearing 28m46s after step start, meaning a 20-minute step timeout could kill a legitimate review before the salvage file exists. - Add a `Salvage review output` step with `if: always()`: prefers `steps.run_codex.outputs.final-message` on a clean exit; falls back to the output file when the step timed out. The output file path is set in the step's own `env` block (`CODEX_OUTPUT_FILE: ${{ runner.temp }}/codex-review.json`), where `runner` is valid. Validates shape (non-empty JSON object, has `overall_risk`); fails the job hard if neither source is present. - Wire the job `outputs.review_json` to `steps.salvage.outputs.review_json`. **Changes (`Justfile`, `ci.yml`):** - Add `actionlint .github/workflows/codex-security-review.yml` to `security-review-check` so expression-validity errors are caught locally. - Provision `actionlint` via Hermit (pinned v1.7.12) rather than a one-off `Install actionlint` curl step, so the same binary is used locally and in CI. **Security posture is unchanged:** the salvage step reads the action's own output and a file written to `runner.temp` — neither is PR-controlled.

This keeps the existing wake policy and gives ACP a narrowly verified effective author: - preserve the workflow owner's existing `p` tag and all rendered-mention `p` tags - add explicit `["buzz:workflow-owner", <owner hex>]` provenance to relay-generated workflow messages - add `["buzz:workflow-mention", <agent hex>]` authority only for mentions resolved from the stored, unrendered workflow step template - accept that owner only for a verified kind-9 event signed by the relay's current NIP-11 `self` key, with unique canonical workflow metadata and an explicit workflow mention for the receiving agent - route the verified owner through the existing author and in-flight mode policies in both normal and setup listeners - refresh relay identity after reconnects, retaining the last verified key on transient fetch errors while treating a successful response without `self` as definitive removal Malformed, duplicate, forged, tampered, wrong-kind, and wrong-relay attribution all fail closed to the raw event signer. `respond-to=nobody` remains absolute. Old/mixed-version messages without the explicit provenance retain their current fail-closed behavior. ## Trust boundary The workflow owner means **“scheduled by,” not “authored every rendered word.”** Trigger-controlled substitutions may still produce ordinary `p` mention routing for compatibility, but they cannot mint `buzz:workflow-mention` authority. Only a target named in the durable owner-authored step template can receive that authority. The author gate is not bypassed: after relay signature/provenance verification, the effective owner is evaluated under the same `owner-only`, `allowlist`, DM, and `nobody` policies used for ordinary messages. Owner control commands continue to use the raw event signer. ## Why this PR This is the focused immediate fix for waking an **online** agent from a stored workflow mention. Earlier attempts were not a finished mergeable fix and had materially different or incomplete trust designs. Larry's larger draft stack addresses durable delivery across restarts; that remains valuable future work and can supersede this effective-author path when it lands. ## Validation At exact clean commit `fe5b55619fe44176343eefb4cb7fe180df45a7d8`: - `buzz-relay workflow_sink`: 25/25 passed, including all four ignored PostgreSQL cases - `buzz-acp --lib`: 845/845 passed - `buzz-workflow --lib`: 169/169 passed (2 unrelated PostgreSQL tests ignored) - warnings-denied Clippy passed for the changed Rust packages - `cargo fmt --all -- --check` passed - `git diff --check` passed - repository pre-push gates passed, including branch-scoped Rust tests - CI now selects the ACP library tests and the relay's pure + PostgreSQL workflow-sink tests so these guards cannot silently remain unexecuted The production event-to-author gate is shared by normal and setup listeners and has biting regression tests for accepted explicit attribution, legacy owner-`p` rejection, and forged-attribution rejection. ## Exact-head local relay + ACP proof Following the release-binary/local-relay shape in `TESTING.md`, the exact commit above passed a fresh isolated real-process matrix using: - a freshly recreated Postgres database with migrations - isolated Redis - exact-head release `buzz-relay`, `buzz`, `buzz-admin`, and `buzz-acp` binaries - newly provisioned owner, channel, and bot member through the CLI - workflow creation and triggering through the running relay - a deterministic ACP protocol subprocess capturing actual `session/prompt` dispatches - a NIP-11 `self` value verified against the running relay signer Cases: 1. A stored explicit workflow mention woke an `owner-only` agent exactly once. 2. A workflow message without an agent mention did not wake it. 3. A non-relay signer forging every workflow authority tag did not wake it. 4. Trigger-controlled `{{trigger.text}}` containing `@Wake Agent` retained ordinary `p` routing but received no authority-bearing workflow-mention tag and did not wake the agent. 5. `respond-to=nobody` remained absolute for a valid relay-authenticated workflow mention. The deterministic ACP subprocess isolates and directly proves relay → ACP authorization and prompt dispatch without depending on external model behavior. ## Deployment and residual risk Relay and ACP changes must be deployed together for the new wake behavior; mixed versions fail closed. Production paired-deployment proof remains distinct from the successful local integration run. Setup-mode behavior has automated coverage but was not a separate case in the five-case local matrix. Relay-key rotation is observed at ACP startup/reconnect; transient NIP-11 errors retain the last verified key, an intentional availability tradeoff documented in code. --------- Signed-off-by: Pinky <5f5ab050ec58ae208332edd544ebf705221e24c1b86d82a6ca07038a7a8f6ac9@buzz.block.builderlab.xyz> Signed-off-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Pinky <5f5ab050ec58ae208332edd544ebf705221e24c1b86d82a6ca07038a7a8f6ac9@buzz.block.builderlab.xyz> Co-authored-by: LioLionel <62820906+LioLionel@users.noreply.github.com> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Co-authored-by: Carl <9d00794d3df50972eb8b615511783cab12a77a8fd5dd5edd58073ec73b54bd8b@buzz.block.builderlab.xyz> * fix(relay): reject a frame on its own acknowledgement channel (#6961) Pinky, an AI agent, updated this description on Wes's behalf after taking over the startup investigation. **Category:** fix **User Impact:** An EVENT refused by WebSocket admission or handler saturation receives a correlated `OK(event_id, false, reason)` instead of an uncorrelated NOTICE, so the client can settle that refusal without waiting for its publish timeout. Rate-limited refusals also arm client backoff. This fixes a protocol failure mechanism; it does not establish that every startup send will succeed or that the reported Desktop startup incident is fully resolved. **Problem:** Startup opens several live subscriptions and publishes at once, and the relay's WebSocket admission gate is a fixed 5-second window (`ws_admission_budget` = `human_ws_events_per_sec * 5`). If that shared per-principal quota is exhausted, `enforce_ws_admission` previously rejected an EVENT with a bare `["NOTICE", reason]`. Quota pressure is a possible trigger, not proof of the original incident's complete cause. A NOTICE carries no event id. Both clients settle a pending publish *only* from an `OK` keyed by event id (desktop `pendingEvents`, mobile `_pendingEvents`), so nothing settled — and `handle_text_message` returns early, so no `OK` ever followed either. The send **could not fail**; it could only time out at `PUBLISH_TIMEOUT_MS` = 25s. That explains how this rejection mechanism can produce a roughly 25-second timeout; attributing the original report to it still requires the actual startup/send workflow. The handler-semaphore saturation path had the identical defect, and that one needs no quota burst to fire. **Solution:** NIP-01 gives each request type its own acknowledgement channel, and a rejection is only actionable on the same one. Reject a REQ with `CLOSED`, an EVENT with `OK(id, false, reason)`, and fall back to `NOTICE` only where no per-request correlation exists. COUNT refusals now also use `CLOSED(query_id, reason)` per NIP-45, covering both quota admission and handler saturation (added in `cd12c93804b87a24b61075dfd171dc471a0a527f`). Reason strings are unchanged, so the `rate-limited:` prefix and `retry in {N}s` hint that existing client gates parse keep working (desktop `parseRateLimitHint`, mobile `RelayRateLimitGate`, buzz-acp `set_rate_limit_gate`). Only the frame *type* changes, so `docs/multi-tenant-relay.md` L7 stays satisfied. Two notes on how this landed, both worth a reviewer's attention: 1. **A survived mutation became a design change.** `send_admission_result` originally took a `RejectionTarget` parameter, and reverting the *second* call site (the per-minute message quota) survived the whole suite — with Redis unreachable the first quota check short-circuits, so that line is unreachable in test. Rather than test around it, the parameter is gone: the target is derived from the frame, so no call site can name the wrong channel. 2. **The relay fix would have caused a client regression on its own.** Gate arming lived only in the NOTICE branch. Once rejections arrive as `OK:false`, `handleOk` failed the send without ever backing off — the client would retry straight into the same quota. Desktop and Mobile now arm on a `rate-limited:` OK rejection. ACP was subsequently fixed in `3b06dd32493596ec650f20abf8805791c50fdc24`: it arms the gate and re-parks only the refused observer frame, preserving other in-flight frames. Desktop gets `activateRateLimitIfSignalled` as the single owner of that prefix test, called from both `handleOk` and the NOTICE branch. <details> <summary>File changes</summary> **crates/buzz-relay/src/rejection.rs** (new) Owns the admission-rejection concern: `RejectionTarget`, `rejection_target_for`, `request_rejection_message`, `send_admission_result`, and `enforce_ws_admission`, moved out of `connection.rs`. Six tests, two of which drive the real `enforce_ws_admission` against a real `AppState`. **crates/buzz-relay/src/connection.rs** Fix the EVENT handler-semaphore rejection to correlate to the event id; delegate admission to the new module. Add two tests that drive the real `handle_text_message` with every handler permit held. Down from 1319 to 1116 lines. **crates/buzz-relay/src/state.rs** Widen the existing `test_state` helper to `pub(crate)` so the rejection tests reuse it rather than adding a ninth copy of `AppState` construction. **desktop/src/shared/api/relayRateLimitGate.ts** Add `activateRateLimitIfSignalled` — one owner for the `rate-limited:` prefix test, since three inbound frame types now carry it. **desktop/src/shared/api/relayClientSession.ts** Arm the gate on a rate-limited OK rejection; route the NOTICE branch through the same helper. Net zero lines, which keeps this already-oversized file within the differential ratchet. **desktop/src/shared/api/relayClientPublishRejection.test.mjs** (new) Four tests against the real `RelayClient`: a rate-limited OK settles the pending publish and arms the gate; an ordinary rejection does not arm it; an accepted OK still resolves. **mobile/lib/shared/relay/relay_session.dart** Arm the gate in `_handleOk` for a rate-limited rejection. **mobile/test/shared/relay/relay_session_test.dart** Two tests driving the real `publish` + `debugHandleMessage` path. </details> <details> <summary>Validation</summary> **Mutation-tested — 5 mutations, all now killed.** Each production call site was reverted to the defective behaviour to confirm a test fails. This caught two false-negative tests: | # | Mutation | Result | |---|----------|--------| | 1 | `rejection_target_for`: EVENT → `Connection` | 4 tests fail | | 2 | EVENT handler-semaphore call site → bare NOTICE | **survived at first** | | 3 | per-minute quota call site → `Connection` | **survived**; fixed by removing the parameter | | 4 | desktop `handleOk` gate arming removed | 1 test fails | | 5 | mobile `_handleOk` gate arming removed | 1 test fails | Mutation 2 is the lesson: my first saturation test called `request_rejection_message` directly, so reverting the real call site inside the `match` arm left it green. It now drives `handle_text_message` itself and dies on that mutation. - `cargo test -p buzz-relay` — 928 passed, 1 failed: `api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo`, **pre-existing**, reproduced with all changes stashed at `4dd4d73de`. - `cd desktop && npm test` — 5721 passed, 0 failed (full suite). - `cd mobile && flutter test` — 1876 passed, 0 failed (full suite). - `just fmt-check`, `just clippy`, `just desktop-check`, `just mobile-check`, `just file-size-check` — clean. Desktop's 5 biome warnings are pre-existing (reproduced with changes stashed). - All 9 pre-push lanes green, including `rust-tests` and `desktop-tauri-checks`. **Not verified:** not reproduced end-to-end against a live relay under a forced quota burst. The causal chain is source-proven and mutation-proven at the frame level; the ~25s attribution follows from `PUBLISH_TIMEOUT_MS` but is not directly measured. A packaged-build click-through would close that gap. </details> Related work: #6957 bounds Desktop HTTP event submission, but safe retained-operation recovery after exhausted/ambiguous outcomes remains unfinished. #6998 is the separately reviewable Desktop readiness/duplicate-subscription slice.

Diagnosis note: `RESEARCH/DESKTOP_STARTUP_SEND_STALL_2026_08_27.md` (Brain's workspace). ## Current review disposition (2026-08-28) The [review on `cd12c938`](https://github.com/block/buzz/pull/6961#pullrequestreview-5052902510) identified ACP's missing rate-limited-OK handling. Commit `3b06dd32493596ec650f20abf8805791c50fdc24` fixes gate arming, re-parking the specifically refused observer frame, and the stale NOTICE comment. Two regressions drive the real frame dispatcher. See [the implementation and validation response](https://github.com/block/buzz/pull/6961#issuecomment-5455032054). The Mobile generation-check inline thread is resolved: its `async publish` returns a failed Future when superseded; it does not throw synchronously at invocation. No further production change was indicated by that comment. The validation counts above describe the original slice, not a new rerun. At `3b06dd324`, the current GitHub check rollup has successful completed test/build checks (non-applicable jobs skipped). The security-review comment still requires review for the current base/head range; do not read a green authorization job as a completed security review. Approval and merge remain human decisions. --------- Signed-off-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Co-authored-by: Carl <9d00794d3df50972eb8b615511783cab12a77a8fd5dd5edd58073ec73b54bd8b@buzz.block.builderlab.xyz> * feat(desktop): add protected-build Bestie experiment (#6902) ## Summary Introduces a protected-build boundary for the default-off Bestie experiment without adding any Bestie product surface. - Official OSS builds select an empty protected-feature module and emit no Bestie/Chief metadata or implementation content. - Protected internal builds select a separate module graph containing the Bestie experiment definition. - Within an internal build, Bestie remains disabled until the user opts in under Settings → Experiments. - The production build runs an artifact matrix and fails if OSS output contains protected content or internal output lacks the Bestie manifest. ## Build contract | Build variant | User opt-in | Result | | --- | --- | --- | | Official OSS | Any/forged | Bestie absent from the compiled artifact | | Protected internal | Off | Bestie available but disabled | | Protected internal | On | Bestie enabled | The companion protected-release change is squareup/buzz-releases#91.

Open **Agents**, edit a custom or built-in agent, and enter a sentence in **Description**. 2. Save the agent and confirm the sentence appears as the second line on its card. 3. Reopen the agent and confirm the authored description is restored; clear it and confirm the card returns to the model label. 4. Paste more than 280 Unicode characters and confirm the field keeps the first 280 characters and shows the near-limit counter. 5. Share or export/import the agent and confirm the description survives in the catalog/profile or snapshot without showing a restart-required badge for a description-only edit. ### Screenshots / Demo The focused Playwright flow `built-in persona edits persist` exercises the edited dialog, persisted value, and resulting card subtitle.

The channel is still the boundary for who is allowed in and what is visible — only the agent's working context is now split by thread. ## How it is turned on Off by default. Operators opt in with one setting: - `BUZZ_ACP_SESSION_POLICY=channel` — default, current behavior - `BUZZ_ACP_SESSION_POLICY=thread` — new per-thread behavior Being behind a flag means we can enable it for a few agents, watch how it behaves, and roll back instantly without a code change. ## Key design decisions - **Decide the thread once, up front.** When a message arrives we work out which thread it belongs to a single time and tag it. Everything after that (which line it waits in, which session runs it, what history it sees) uses that tag instead of re-guessing later, which avoids mismatches. - **Default stays identical to today.** Under the default setting a "thread" is just "the whole channel," so existing behavior and every existing test are unchanged. The new, riskier behavior is strictly opt-in. - **Give the agent only its thread's history.** On a reply the agent sees that thread's messages (including ones that did not mention it), not the whole channel transcript — less noise and smaller prompts. - **Don't let one channel use more memory than before.** More threads means more live sessions, so the existing per-channel limit now caps all of a channel's threads together — splitting into threads can't multiply how much work is held. ## Bugs found and fixed while iterating (from review) - **Same thread, two sessions.** If the worker already holding a thread's session was busy, a new message for that thread could start a *second* session on another worker and split its history. Now it waits for the right worker instead of forking. - **Interrupting the wrong thread.** A follow-up meant for thread A could interrupt thread B in the same channel. Interrupts now target the exact thread. - **Stuck thread after a crash.** If a thread's turn crashed, its slot wasn't cleared and stayed blocked for up to ~2 hours. It now clears right away and retries. - **Lost the original request.** When a thread was interrupted and then had to wait for a busy worker, only the follow-up was kept and the original request was dropped. The full request is now preserved on retry. - **Same thread seen as two.** Two spellings of the same thread id (upper/lower case) could be treated as different threads. Normalized so they count as one. ## Not in this PR - The desktop Settings toggle and rollout wiring for managed agents — https://github.com/block/buzz/pull/6909 - One pre-existing retry edge case (present today without this flag, unrelated to this change) — tracked separately so this PR stays focused. ## Testing The full `buzz-acp` test suite passes (830+ unit and integration tests), plus new focused tests for thread routing, session reuse, interrupt targeting, crash recovery, and request preservation. Behavior with the flag off is unchanged. --------- Signed-off-by: Salman Mohammed <smohammed@squareup.com> Signed-off-by: Leo <5faf251baee50ee6bcde338aef6acdd70bb3e60115664c2cd490d94a55dfc488@buzz.block.builderlab.xyz> Co-authored-by: Leo <5faf251baee50ee6bcde338aef6acdd70bb3e60115664c2cd490d94a55dfc488@buzz.block.builderlab.xyz> * feat(db): add NIP-FI identity and final-admission schema foundation (#6994) PR 2 of the NIP-FI plan: the schema foundation. Establishes the durable server-side identity ledger and final-admission surface that the runtime phases build on. All of Phase A's migrations live here; later phases own their own deltas. Depends on nothing — PR 1 (#6776, merged) owned zero migration files. This PR's relations are shaped to store exactly what PR 1's verifier produces: issuer-qualified identity and the four denial classes. They meet in a later PR that writes a verified assertion into these tables in one transaction. ## Two internally-ordered migrations - `0041_nip_fi_identity_foundation.sql` (migration A) — core identity + base-lifecycle relations (5 tables): issuer-qualified `(iss, sub)` bindings, lifecycle history/selectors, enrollment policies, and operation receipts. Applies cleanly to current `main`. - `0042_nip_fi_authorization_foundation.sql` (migration B) — the final-admission surface (10 tables): authorization events + capacity, admission results, replay/receipt guards, audit, invalidation domains/floors, protected-object authority, authority epochs, and restore version deltas. Applies to A's resulting state. Fifteen NIP-FI relations total, zero dangling foreign keys. Identity is issuer-qualified throughout — no single-global-issuer assumption in any relation, no `Block`-hardcoding. A single deployment may run one issuer; that is config, not schema. ## Durable, immutable ledger posture All 15 relations are append-only (immutable `no_delete`/`no_truncate` triggers) and carry `community_id` as provenance, not ownership. Both migrations widen the single SQL source of truth `community_write_fence_excluded_table` so the relations are never fence-attached, never purged on community deletion, and never counted as tenant-scoped drift by the deletion control plane's exact-set catalog check — the same posture main already applies to `product_feedback` and `rate_limit_violations`. `schema/schema.sql` keeps one consolidated definition of that function whose exclusion array byte-matches `0042`, guarded by a parity assertion so a future consolidation cannot silently drop NIP-FI relations from the ledger. This makes a tenant's identity/authorization ledger survive community deletion, per the spec's `FI-INV-02` (durable binding) and `FI-INV-03` (tombstone monotonicity) and `NIP-FI.md`'s "durable server state" ruling. `communities(id)` FK never dangles: community rows become permanent tombstones, never hard-deleted. ## Authorization shape and cardinality contracts Authenticated `OperatorDenied` events (`actor_kind` 1–3, non-null `request_fingerprint`) carry a null `semantic_fingerprint` and commit without a denial-attempt row. The denial-attempt cardinality and shape guards are scoped to unresolved pre-auth kind-9 events (`actor_kind = 4`). Applied and no-op lifecycle receipts (`outcome_code IN (1, 3)`) require exactly one mapped success-transition event; denied lifecycle receipts (`outcome_code = 2`) require zero events from the complete core lifecycle success-transition class (kinds 1, 2, 3, 6: enrolled, revoked, rotated, retired) — any such event paired with a denied receipt would record a transition that never occurred. ## Mined vs. new Re-cut from Franco's #1476 (`0029`/`0030`) and Cea's #4772 committer schema, re-cut along FK topology and renumbered above the live `main` tip. The buzz-auth core of #1476 is Cea-authored; `Co-authored-by` reflects verified per-commit authorship of the mined schema. Zero Rust/`deletion.rs` edits — the migration-only exclusion widening keeps `EXPECTED_SCOPED_TABLES` untouched. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> Co-authored-by: Cea Stapleton Cordasco <261786559+cea@users.noreply.github.com> Co-authored-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> * fix(model-capabilities): humanize databricks goose model names (#7135) 🤖 ## Summary - add curated human-readable labels for Databricks Goose models that otherwise render as fully qualified identifiers - render `data_workflow_tools.goose.goose-glm-5-3` as `GLM-5.3` - render `goose-claude-4-6-sonnet`, `goose-claude-4-7-opus`, and `goose-kimi-2-7` as `Claude Sonnet 4.6`, `Claude Opus 4.7`, and `Kimi 2.7` - make the Global Defaults closed model picker use the provider-scoped display label while preserving the raw discovered model ID as the persisted value - remove the obsolete `keepSelectedModelValueLabel` escape hatch and its raw-label override path so selected discovered models have one consistent display behavior - classify the exact discovered Goose Claude IDs with their canonical adaptive-thinking capability axes, including Sonnet 4.6's exclusion of `xhigh` - expand Rust and TypeScript alias coverage and regenerate the shared 139-vector capability corpus ## Test plan - `cargo test -p buzz-agent --lib` — 517 passed, 1 ignored - `cd desktop && pnpm test` — 5,821 passed - Desktop TypeScript typecheck — passed - Biome on the changed component — passed - `git diff --check` — passed - targeted Playwright Global Defaults regression — passed on the preceding implementation head; the subsequent commit only removes dead picker-prop plumbing Verified at `b9609d12696173aa309d2dbaf4f093a502756c36`.

The existing production release recipe is unchanged. - Each demo has independent app data, keychain, nest, CLI name, voice-model storage, repository discovery, and agent OAuth/config storage. Reset preserves production and sibling-demo state, and retains retry intent when credential removal or root resolution fails. - Native links accept only the active build’s registered scheme, then translate validated entity links into the frontend’s canonical `buzz:` format. - The recipe builds all six executable sidecars. Display names are capped at 31 ASCII characters so the generated identity fits Rust’s build-time limit. **Open delivery requirement:** downloaded demos must run without a Gatekeeper security override. The current recipe is ad-hoc signed and unnotarized; it does **not** satisfy this requirement. Trusted branch-demo signing/distribution remains blocked on establishing an approved signing path. This PR is not being presented as complete download-and-run delivery. ### Related issue N/A — reported in the Buzz DMG-packaging workstream. ### Testing At `11ce21ff97cb387ad676e7caa65b00964097d0bb`, macOS Blox passed the Tauri workspace suite and compiled-flags gate (including the full named-demo state; each library pass: 2,992 passed, 19 ignored), Tauri all-target clippy, the full `buzz-agent` package suite, and frontend lint/typecheck plus 5,733 tests. Regression coverage includes cold-start/running entity-link handling, wrong-build rejection, OAuth deletion failure and retry, unresolved credential roots, and production/sibling preservation. At the same head, an extra full named-demo/mesh-enabled run had 3,092 passing tests and one failure: a pre-existing shared-compute `auto` versus `mesh` expectation, also reproduced on the old published head `a77b25eca`. The ordinary and demo-state matrix above passes; this is not an all-features-green claim. Live macOS Launch Services delivery remains unverified. GitHub CI completed with 30 successful checks and 9 skipped. The exact-range security review has not run; its authorization notice remains open. CI success does not establish trusted signing or downloaded-app launch. Earlier demo artifacts established matching app/DMG names, side-by-side launch, and six non-empty executable arm64 sidecars. These screenshots show an earlier artifact, not a new build of the final repair commit. Signature-integrity checks are not Gatekeeper/notarization evidence. <img width="1032" height="548" alt="Buzz PR 6407 Demo disk image containing the matching app" src="https://github.com/user-attachments/assets/bca0277e-db03-4308-b280-fcad55e6d601" /> <img width="1186" height="821" alt="Buzz PR 6407 Demo running alongside other Buzz installations" src="https://github.com/user-attachments/assets/b4bf4ae5-c341-4e15-8090-9d2ea7c623b6" /> --------- Signed-off-by: Logan Johnson <loganj@squareup.com> Signed-off-by: Larry <8cf5a83f590ec0955b11647d1c88f796a98e088c30a492c58e0e46c3026ae7a4@buzz.block.builderlab.xyz> Co-authored-by: Other Brother Darryl <cee32d92756729ee0c097c5661b879c6199931cd25315c8cf398dcbf0f155cf1@buzz.block.builderlab.xyz> Co-authored-by: Larry <loganj+sandbox-larry@squareup.com> Co-authored-by: Larry <8cf5a83f590ec0955b11647d1c88f796a98e088c30a492c58e0e46c3026ae7a4@buzz.block.builderlab.xyz> --------- Signed-off-by: Philip Azar <pazar@squareup.com> Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Fizz <dae5f6af70b8695a8b83c8deae555f63be41630ec2b8cd493e41a439c9527dd8@buzz.block.builderlab.xyz> Signed-off-by: Pinky <5f5ab050ec58ae208332edd544ebf705221e24c1b86d82a6ca07038a7a8f6ac9@buzz.block.builderlab.xyz> Signed-off-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Signed-off-by: Wes <wesbillman@users.noreply.github.com> Signed-off-by: Arjun Mahanti <arjun@squareup.com> Signed-off-by: Fizz <fizz@buzz.local> Signed-off-by: tulsi <tulsi@block.xyz> Signed-off-by: Wintermute <c0fc581234c3585602139eec347ced7b82af65b6f6c10728348515c0c06c51c3@buzz.block.builderlab.xyz> Signed-off-by: Jude Edwards <judeedwards@squareup.com> Signed-off-by: Salman Mohammed <smohammed@squareup.com> Signed-off-by: Leo <5faf251baee50ee6bcde338aef6acdd70bb3e60115664c2cd490d94a55dfc488@buzz.block.builderlab.xyz> Signed-off-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> Signed-off-by: Kalvin Chau <kalvin@block.xyz> Signed-off-by: Logan Johnson <loganj@squareup.com> Signed-off-by: Larry <8cf5a83f590ec0955b11647d1c88f796a98e088c30a492c58e0e46c3026ae7a4@buzz.block.builderlab.xyz> Signed-off-by: shiv <shivchander.s30@gmail.com> Co-authored-by: Phil Azar <pazar@squareup.com> Co-authored-by: Will Pfleger <pfleger.will@gmail.com> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Arjun Mahanti <arjun.mahanti@gmail.com> Co-authored-by: Fizz <dae5f6af70b8695a8b83c8deae555f63be41630ec2b8cd493e41a439c9527dd8@buzz.block.builderlab.xyz> Co-authored-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Pinky <5f5ab050ec58ae208332edd544ebf705221e24c1b86d82a6ca07038a7a8f6ac9@buzz.block.builderlab.xyz> Co-authored-by: LioLionel <62820906+LioLionel@users.noreply.github.com> Co-authored-by: Brain <1a02c72794dcd0f07058a353bc3a81f4028b8c77c92c87fce6d5c8b85970a20b@buzz.block.builderlab.xyz> Co-authored-by: Carl <9d00794d3df50972eb8b615511783cab12a77a8fd5dd5edd58073ec73b54bd8b@buzz.block.builderlab.xyz> Co-authored-by: Codex <noreply@openai.com> Co-authored-by: Fizz <fizz@buzz.local> Co-authored-by: tulsi <tulsi@block.xyz> Co-authored-by: thomaspblock <thomasp@squareup.com> Co-authored-by: Wintermute <c0fc581234c3585602139eec347ced7b82af65b6f6c10728348515c0c06c51c3@buzz.block.builderlab.xyz> Co-authored-by: Jude Edwards <judeedwards@squareup.com> Co-authored-by: Salman Mohammed <smohammed@squareup.com> Co-authored-by: Leo <5faf251baee50ee6bcde338aef6acdd70bb3e60115664c2cd490d94a55dfc488@buzz.block.builderlab.xyz> Co-authored-by: Cea Stapleton Cordasco <261786559+cea@users.noreply.github.com> Co-authored-by: Hayt <9e1c23a3fd83f61da34420e4e88ff1b16e45cafcc0cd9019eb07d4ecfa8ca9b0@buzz.block.builderlab.xyz> Co-authored-by: Kalvin C <kalvinnchau@users.noreply.github.com> Co-authored-by: am <6e30cd56c30e030cd31bb0939b94a7c257c9a09d5ba2d92cf2735da45629f248@buzz.block.builderlab.xyz> Co-authored-by: Logan Johnson <loganj@squareup.com> Co-authored-by: Other Brother Darryl <cee32d92756729ee0c097c5661b879c6199931cd25315c8cf398dcbf0f155cf1@buzz.block.builderlab.xyz> Co-authored-by: Larry <loganj+sandbox-larry@squareup.com> Co-authored-by: Larry <8cf5a83f590ec0955b11647d1c88f796a98e088c30a492c58e0e46c3026ae7a4@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
