From bafdff958a03eed0e09cebe8c1a539b40c5e5e99 Mon Sep 17 00:00:00 2001 From: Will Pfleger Date: Fri, 28 Aug 2026 12:01:28 -0400 Subject: [PATCH 01/19] feat(db): add NIP-FI identity + final-admission schema foundation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce the Phase-A NIP-FI schema as two internally-ordered migrations: 0040 lays down the core identity and base-lifecycle relations, and 0041 applies to 0040's resulting state to add the final-admission surface (replay/receipt, audit events, invalidation, capacity, protected-object authority, restore version deltas, and the closed admission result). Identity is issuer-qualified (iss, sub) with no hardcoded issuer. All 15 NIP-FI relations are a durable, immutable, append-only security ledger: both migrations widen the single SQL source of truth community_write_fence_excluded_table so the relations are never fence-attached, purged on community deletion, nor counted as tenant-scoped drift by the deletion control plane's exact-set catalog check — the same posture as product_feedback and rate_limit_violations. schema.sql keeps one consolidated definition of that function whose body byte-matches 0041.

charset=UTF-8 Content-Transfer-Encoding: 8bit The FK on identity_bindings previously equated binding_provenance with the enrollment policy's enrollment_mode via a composite reference: (community_id, policy_revision, binding_provenance) → identity_enrollment_policies (community_id, policy_revision, enrollment_mode) This contract-breaks NIP-FI §352 and §424: provenance is determined from operation evidence, not the policy mode. A TOFU-mode policy (mode=3) with an attested-key binding (provenance=1) — a valid and specified admission path — would fail at commit with a FK violation. Narrow the FK to (community_id, policy_revision) → (community_id, policy_revision), which is already the PK of identity_enrollment_policies. The redundant UNIQUE (community_id, policy_revision, enrollment_mode) on identity_enrollment_policies is removed; it existed only to satisfy the old composite FK and has no other consumer. Both changes applied in lockstep to the migration and the schema.sql mirror. The parity assertion in admin_schema_parity_between_desired_state_and_migrations continues to hold. Add behavioral regression identity_binding_provenance_is_independent_of_enrollment_mode: seeds a TOFU-mode policy, inserts an attested-key binding in a single deferred transaction, and asserts the commit succeeds with provenance=1 and mode=3 persisted independently. Mutation-verified: restoring the composite FK causes the test to fail with the exact FK violation (code 23503) the fix removes.

charset=UTF-8 Content-Transfer-Encoding: 8bit Extends identity_binding_provenance_is_independent_of_enrollment_mode with the negative half required for two-sided mutation sensitivity. A second deferred transaction inserts an otherwise-valid identity_bindings row referencing policy_revision 999 (nonexistent in identity_enrollment_policies) and asserts the INSERT fails with SQLSTATE 23503 from the narrowed FK identity_bindings(community_id, policy_revision) → identity_enrollment_policies(community_id, policy_revision). Non-vacuity verified: removing the FK from the migration causes the absent-policy INSERT to succeed (rows_affected: 1) and the expect_err assertion to fire, confirming the negative half detects a dropped or neutered FK. The existing positive half catches the old composite FK; together they give full two-sided coverage. Zero production changes: migrations 0040/0041 and schema.sql are byte-untouched.

Uses a per-community advisory lock via hashtextextended so concurrent writers serialize the max-revision read, then asserts both policy_revision and effective_at strictly exceed the current community maximum (FI-INV-06 — stable assertion policy). Finding 2 (admission result ↔ kind-11 receipt cardinality): add authorization_admission_result_guard_v1(), bidirectional deferred constraint trigger on both authorization_operation_receipts (kind-11 receipt must have exactly one result) and authorization_admission_results (result must attach to a kind-11 receipt). Mirrors the pattern of the existing authorization_operation_receipt_event_guard_v1. Finding 3 (denial event ↔ attempt binding): add authorization_denial_attempt_guard_v1(), bidirectional deferred constraint trigger on both authorization_events (kind-9 event must have exactly one denial attempt) and authorization_authentication_denial_attempts (attempt must reference an existing kind-9 event). The existing FK binds (audit_event_kind=9) but does not require a kind-9 event to have a matching attempt row; this guard closes that gap.

Drop effective_at monotonicity from policy revision guard identity_enrollment_policy_revision_guard_v1() now enforces only strict-greater policy_revision per community. The effective_at check had no NIP-FI basis (FI-INV-06 defines assertion_policy_id stability, not revision chronology) and would reject legitimately-sequenced revisions — the downstream constructor stamps every immediately- effective revision with Unix epoch, so revision 2 would fail after revision 1 under the old guard. 2. Bind semantic coordinates in denial attempt guard authorization_authentication_denial_attempts gains attempt_id UUID NOT NULL with a deferred FK to authorization_events on (community_id, operation_id, event_kind, attempt_id). The guard authorization_denial_attempt_guard_v1() now additionally compares correlation_id and reason_code between the event and its denial attempt row, raising check_violation (23514) with named constraint authorization_denial_attempt_semantic_binding on mismatch. This closes the Carl finding 3 gap: a kind-9 event for correlation A / reason X can no longer be paired with a denial row carrying correlation B / reason Y. 3. Rewrite regression tests to prove the contracts - Policy test: seeds a gap (100->101) then inserts unused revision 99 and asserts 23514 from the named guard (not 23505, which would fire on a PK duplicate and not prove the monotonic comparison). Adds a two-transaction concurrency regression: two distinct forward revisions (102, 103) race through separate connections; both commit because the advisory lock serializes them and each is valid. - Denial test: replaces the ambiguous negative-B (23503 OR 23514) with three single-coordinate-mismatch cases attributed to the named guard: B1 correlation_id mismatch (23514), B2 reason_code mismatch (23514), B3 attempt_id mismatch (23503 via deferred FK). - Admission test: adds negative C -- mismatched request_fingerprint rejected by the immediate composite FK (23503) at INSERT, proving the coordinate binding half of Carl finding 2. All four changed files byte-identical between migration files and schema/schema.sql (verified by extraction+cmp). All 5 NIP-FI tests, admin_schema_parity, and 2 unit tests pass.

This is the redaction-safe intent_digest coordinate. - Add authorization_denial_reason_reason_code_binding CHECK to authorization_authentication_denial_attempts: encodes the canonical OperatorAuthenticationDenialReason <-> AuthorizationReasonCode mapping from operator_lifecycle.rs:700-706 and authorization_events.rs:215-226: MissingCredential(1)<->Missing(2), InvalidCredential(2)<->Invalid(3), Unauthenticated(3)<->Unauthenticated(4). Fires at INSERT, not COMMIT. - Extend authorization_denial_attempt_guard_v1() to compare semantic_fingerprint between event and denial attempt in both firing directions, raising 23514 'authorization_denial_attempt_semantic_binding' on mismatch. Carl's mismatched-reason and mismatched-fingerprint cross-attachments are now fully closed. IMPORTANT 2 (concurrency regression): Replace the 10ms-sleep approach with a tokio::sync::Barrier(2) that holds both connections after BEGIN and before INSERT. Both race to pg_advisory_xact_lock; one blocks, the winner commits, the loser sees MAX=102 and fails with 23514 (not 23505). XOR assertion proves exactly one INSERT succeeds, and the loser's 23514 (not PK 23505) proves the advisory lock — not just PK uniqueness — is the serialization mechanism. Contradictory comments fixed. MINORs (folded in): - Fix stale test doc comment claiming effective_at must advance (it does not; the downstream constructor stamps Unix epoch for immediate policy). - Fix equal-revision comment incorrectly claiming different policy_digest avoids the PK; the PK is (community_id, policy_revision). CI fmt failure: cargo fmt --all run; whitespace-only reformatting of some query blocks in migration.rs. Regressions added/updated: - B4: denial_reason/reason_code mapping violation rejected at INSERT by the immediate CHECK (23514 from authorization_denial_reason_reason_code_binding). - B5: semantic_fingerprint mismatch between event and denial attempt rejected at COMMIT by the deferred guard (23514 from authorization_denial_attempt_semantic_binding). Byte-parity (extraction+cmp): - authorization_events table: 3394 bytes, migration == schema.sql - authorization_authentication_denial_attempts table: 2062 bytes, migration == schema.sql - authorization_denial_attempt_guard_v1(): 5579 bytes, migration == schema.sql - identity_enrollment_policy_revision_guard_v1(): 1113 bytes, migration == schema.sql - authorization_admission_result_guard_v1(): 2164 bytes, migration == schema.sql All five NIP-FI tests green locally (run in isolation to avoid pre-existing pool-state flakiness in the full suite).

That construction synchronizes client-side INSERT dispatch, not trigger execution; a lock-free schedule where one INSERT completes and commits before the other reads MAX still satisfies the XOR + 23514 assertions, so the test offered no deterministic proof that pg_advisory_xact_lock is required. Replace with a controlled two-connection schedule: 1. tx1 opens a transaction and inserts revision 102. The BEFORE INSERT trigger acquires pg_advisory_xact_lock and completes; tx1 holds the advisory lock until commit. 2. tx2 opens a transaction on a second backend, reports its pg_backend_pid over a oneshot channel, then issues INSERT for revision 103. The trigger fires and blocks on the advisory lock held by tx1. 3. The main task polls pg_stat_activity WHERE pid = tx2_pid AND wait_event_type = 'Lock' AND wait_event = 'advisory' with a 10 s bounded timeout. Without pg_advisory_xact_lock in the guard the trigger returns immediately, tx2 never enters the advisory wait, and the poll times out — making the regression deterministically red. 4. tx1 commits, releasing the lock. tx2 unblocks, its trigger reads the fresh MAX=102, and INSERT 103 succeeds. tx2 commits. 5. Final count asserts six revisions (1, 2, 100, 101, 102, 103). Zero production changes: migrations/0041, migrations/0042, and schema/schema.sql are byte-untouched (single-file diff confirmed).

Scope the non-zero semantic_fingerprint constraint to actor_kind = 4 (require NULL for actor_kind 1–3). On the event side, skip the denial-attempt guard when actor_kind ≠ 4. On the attempt side, add a shape guard that rejects binding to any event with actor_kind ≠ 4 or non-null request_fingerprint, named authorization_denial_attempt_event_kind so the attribution is distinguishable from the pre-existing semantic-binding check. **Lifecycle receipt outcome cardinality (IMPORTANT):** The lifecycle-event guard fired for denied lifecycle receipts (outcome_code = 2), requiring a fabricated transition event. Apply event cardinality only for outcome_code IN (1, 3), matching the stated successful/no-op contract. A denied receipt now commits without a paired audit event. **Stale migration-number comments (MINOR):** Three comments in 0042 still referenced migration 0040 after the identity migration was renumbered to 0041. Updated to 0041. **Trailing EOF blank (MINOR):** Removed extra blank line at end of schema/schema.sql; git diff --check is now clean. **CI wiring:** Excluded per Will's ruling — Luke owns the PostgreSQL CI lane. New regressions added to migration.rs (both #[ignore = "requires Postgres"]): - authenticated_kind_9_denial_commits_without_denial_attempt: positive A commits an authenticated denial without a denial-attempt row; negative B proves a denial-attempt cannot attach to the authenticated event, assertion keyed on exact constraint name authorization_denial_attempt_event_kind. - denied_lifecycle_receipt_commits_without_audit_event: a denied enroll receipt commits standalone; guard skips outcome_code 2. Mutations verified red: 1. Removing actor_kind gate from event-side trigger → positive A fails (COMMIT rejected, no attempt row present). 2. Removing actor_kind shape guard from attempt-side → negative B fails with authorization_denial_attempt_semantic_binding instead of authorization_denial_attempt_event_kind. 3. Removing outcome_code NOT IN (1, 3) gate → denied-receipt positive fails. All 9 NIP-FI PostgreSQL regressions pass at the corrected head.

The previous blanket RETURN NULL for outcome_code NOT IN (1, 3) let a denied receipt commit alongside its mapped success-transition event, creating contradictory durable ledger facts: denial plus enrolled/retired/revoked/rotated. Replace the early return with a three-way branch in authorization_operation_receipt_event_guard_v1(): outcome_code IN (1, 3) — exactly-one mapped event (unchanged) outcome_code = 2 — zero events of the mapped transition kind; raises authorization_denied_lifecycle_receipt_no_success_event other — skip (not a core lifecycle outcome) Both deferred trigger directions share the same function body; a single transaction with both INSERT paths exercises both directions at COMMIT. The new negative fixture inserts a denied enroll receipt plus its mapped success-transition event (event_kind = 1) in one transaction and asserts COMMIT rejection with the exact constraint name. Mutation: stashing the ELSIF branch lets COMMIT succeed, so expect_err panics — confirming the branch is load-bearing (verified red). Also correct three stale doc comments: - Remove the "COMMIT succeeds" claim in the attempt-side shape guard mutation note; accurately state the pre-existing semantic-binding constraint fires instead. - Remove the false claim that denial-attempt/admission-result tests protect applied/no-op lifecycle; replace with accurate coverage note. - Update the semantic_fingerprint column comment to distinguish unresolved pre-auth kind-9 (actor_kind = 4) from authenticated kind-9 (actor_kind 1-3). All changes byte-mirrored between migration 0042 and schema/schema.sql. All 9 NIP-FI ignored PostgreSQL regressions pass (--test-threads=1).

Event-side trigger isolation The denied-receipt-then-event negative in denied_lifecycle_receipt_commits_without_audit_event queues both deferred triggers in one transaction; it does not prove the event-side trigger (authorization_event_receipt_cardinality) alone. Add denied_lifecycle_receipt_event_side_trigger_isolated: commit a denied receipt in auto-commit (no deferred trigger active), then open a new transaction that inserts only the mapped success-transition event and asserts COMMIT rejection with the exact constraint name. Rejection must come from the event-side trigger only. 2. Applied lifecycle coverage at migration 42 No test exercised the outcome_code IN (1, 3) branch at migration 42. Add applied_lifecycle_receipt_requires_exactly_one_event: an applied enroll receipt + exactly one mapped event commits; the same setup without the event rejects with authorization_operation_receipt_event_cardinality. Uses the minimum valid circular identity/lifecycle setup (policy + history + receipt + binding + event), stops at migration 42 not 41. 3. Correct surrounding mutation/coverage comments - denied_lifecycle_receipt_commits_without_audit_event: update mutation note to name both new tests, remove the stale claim that the receipt-then-event negative covers both trigger directions. - The receipt-then-event negative comment is tightened to say only the receipt-side trigger fires in that transaction. No production SQL changes. All 11 NIP-FI ignored PostgreSQL regressions green (--test-threads=1).

charset=UTF-8 Content-Transfer-Encoding: 8bit Add the JWKS discovery/caching layer, startup validation gate, and NIP-11 discovery output that complete the NIP-FI assertion runtime. The verifier (PRs 1–2) already defined the sealed IssuerKeySource trait and AssertionKeySet constructor as placeholders for this PR. This PR fills that contract with a production implementation: - jwks: ProductionJwksSource implements IssuerKeySource via an injectable JwksFetcher trait (sealed; HttpJwksFetcher for production). Bounded periodic refresh; coalesced in-flight; try_read/try_lock for async-safe synchronous key_set() path. Never serves an expired snapshot; fails closed on fetch/parse error. [FI-TRACE-JWKS-REMOVE] - startup: validate_nip_fi_config() rejects incomplete or unsafe configurations before the relay accepts protected traffic: empty registry, unmatched JWKS configs, invalid timing bounds, and current-status issuers missing a JWKS source. Off/DenyProtected modes accept without validation. [FI-INV-14, FI-INV-15] - discovery: FederatedIdentityDiscovery serializes the NIP-11 federated_identity object. Never exposes enrollment mode, issuer URLs, audiences, or deployment-local identifiers. [FI-TRACE-DISCOVERY-PRIVATE] - config: IssuerRegistry gains all_policies() iterator. - verifier: sealed module promoted to pub(crate) for jwks access; AssertionKeySet::new #[allow(dead_code)] removed (now has real caller). Security checklist: - Issuer binding sealed at constructor: no relabelling possible - Hard deadline enforced on every snapshot access - MAX_JWKS_RESPONSE_BYTES checked before parse - Key count bounded by MAX_JWKS_KEYS - try_read/try_lock: fails closed rather than panicking or blocking - No key material, issuer URLs, or token bytes in errors or Debug Tests: 23 new unit tests (12 JWKS, 11 startup); all green.

charset=UTF-8 Content-Transfer-Encoding: 8bit HTTP boundary (finding 1): - Add validate_jwks_uri(): HTTPS-only, no credentials/fragments, bare IP private-address rejection via buzz_core::network::is_private_ip - HttpJwksFetcher::new() builds a hardened client: no redirects, 10s intrinsic deadline; with_client() documents caller invariants - Stream response body incrementally (bytes_stream + StreamExt), stop at MAX_JWKS_RESPONSE_BYTES + 1 before any deserialization - Reject non-2xx status before reading body - Add reqwest 'stream' feature to workspace; add futures-util to buzz-auth deps - Add MAX_JWKS_TIMING_SECONDS = 1 year upper bound on timing fields - Regression tests: non-HTTPS, loopback/private IP, credentials, fragment, oversized timing, duplicate issuer all rejected at construction CurrentStatus posture (finding 2): - Rename error variant DuplicateIssuer(String) -> DuplicateIssuer (sanitized) - Add UnsupportedPosture error variant - validate_nip_fi_config() rejects any CurrentStatus policy with UnsupportedPosture — verifier has no status witness; startup fails closed - discovery.rs: remove FreshnessClassDiscovery::CurrentStatus variant and FederatedIdentityDiscovery::current_status() constructor entirely - Test asserts rejection both with and without JWKS config Duplicate issuer detection (finding 3): - validate_nip_fi_config(): explicit duplicate detection in JWKS config slice (collect() was silently overwriting); returns DuplicateIssuer on collision - ProductionJwksSource::new(): rejects duplicate issuer via HashMap::contains_key before insert Timing bounds and overflow (finding 4): - MAX_JWKS_TIMING_SECONDS constant bounds both refresh and hard-deadline fields - i64::try_from() + Duration::try_seconds() eliminates u64->i64 cast panic - Validated at both ProductionJwksSource::new() and validate_nip_fi_config() - Test: new_rejects_timing_above_maximum() Generation monotonicity (finding 5): - Replace wall-clock millis with SHA-256 content digest per issuer - Generation counter advances (saturating_add) only when digest changes; identical documents preserve the prior generation - Regressions: generation_stable_for_identical_document(), generation_advances_for_changed_document() Clippy (finding 6): - manual_async_fn: replaced RPITIT form with native 'async fn' in impl block - single_match (startup): replaced match { None => .., Some(_) => {} } with if let / !contains_key - unnecessary_get_then_check: replaced .get().is_none() with !contains_key() Comment quality (all files): - Remove module-to-PR table from nip_fi/mod.rs - Remove all 'Phase A', 'PR 1/3', 'PRs 4-5' references from every doc comment - Remove WHAT comments (field-name paraphrases, narrated steps, section banners with no contract content, 'Construct with a default reqwest client') - Retain WHY: security invariants, exact NIP-FI spec refs, fail-closed choices, FI-TRACE/FI-INV stable identifiers Co-authored-by: Cea Stapleton Cordasco <261786559+cea@users.noreply.github.com> Co-authored-by: Will Pfleger Signed-off-by: Will Pfleger --- Cargo.lock | 1 + Cargo.toml | 2 +- crates/buzz-auth/Cargo.toml | 1 + crates/buzz-auth/src/nip_fi/discovery.rs | 53 +-- crates/buzz-auth/src/nip_fi/jwks/mod.rs | 333 +++++++++++-------- crates/buzz-auth/src/nip_fi/jwks/tests.rs | 305 +++++++++++++++-- crates/buzz-auth/src/nip_fi/mod.rs | 25 +- crates/buzz-auth/src/nip_fi/startup/mod.rs | 148 ++++----- crates/buzz-auth/src/nip_fi/startup/tests.rs | 109 +++--- 9 files changed, 636 insertions(+), 341 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index cc28cbf6263..552a12ca155 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -939,6 +939,7 @@ dependencies = [ "base64 0.22.1", "buzz-core", "chrono", + "futures-util", "hex", "jsonwebtoken", "nostr 0.44.7", diff --git a/Cargo.toml b/Cargo.toml index d6ee839f1b0..0af365f52fe 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -104,7 +104,7 @@ chrono = { version = "0.4", features = ["serde"] } jsonwebtoken = { version = "10.4.0", default-features = false, features = ["aws_lc_rs"] } # HTTP client (webhook delivery) -reqwest = { version = "0.13", features = ["json", "rustls"], default-features = false } +reqwest = { version = "0.13", features = ["json", "rustls", "stream"], default-features = false } # Cryptography sha2 = "0.11" diff --git a/crates/buzz-auth/Cargo.toml b/crates/buzz-auth/Cargo.toml index 13dbdd88564..158d282cd61 100644 --- a/crates/buzz-auth/Cargo.toml +++ b/crates/buzz-auth/Cargo.toml @@ -21,6 +21,7 @@ base64 = { workspace = true } chrono = { workspace = true } jsonwebtoken = { workspace = true } nostr = { workspace = true } +futures-util = { workspace = true } reqwest = { workspace = true } serde = { workspace = true } serde_json = { workspace = true } diff --git a/crates/buzz-auth/src/nip_fi/discovery.rs b/crates/buzz-auth/src/nip_fi/discovery.rs index 359844342dc..8d1b1500b12 100644 --- a/crates/buzz-auth/src/nip_fi/discovery.rs +++ b/crates/buzz-auth/src/nip_fi/discovery.rs @@ -1,7 +1,8 @@ -//!

trim internal markers - Remove with_client() bypass: HttpJwksFetcher is now a unit struct; each fetch_jwks call builds a dedicated per-request pinned client. - Add resolve_and_check_ssrf: DNS-resolves host:port via spawn_blocking, rejects any resolved private/reserved IP (closes DNS-rebinding TOCTOU). - Per-request client enforces: redirect(Policy::none()), no_proxy(), .resolve(host, pinned_ip), and timeout(JWKS_REQUEST_TIMEOUT_SECS). - Drop unused client field (dead_code warning) now that no shared pool is needed. - Remove pure-paraphrase doc on IssuerRegistry::all_policies(); replace with doc stating constraint (unspecified order, startup use). - Remove all 'PR N' internal markers from doc comments; replace with production-stable references to the jwks runtime.

HTTP/credentials/fragment URIs rejected before any DNS resolution or connection attempt. - Introduce with_deadline(fut, duration): private generic helper that wraps any future in tokio::time::timeout. HttpJwksFetcher::fetch_jwks passes fetch_jwks_inner(uri) through it with the fixed 10-second constant. Remove the RequestBuilder::timeout — the outer deadline covers the whole operation including a stalled OS resolver. - Add with_deadline_fires_before_outer_guard: tokio::test(start_paused) passes std::future::pending() to with_deadline with Duration::ZERO. The inner timeout fires immediately; removing it leaves the future permanently pending and the outer test guard fires — seam verified. - Fix IPv6-literal handling in resolve_and_check_ssrf: use (host, port) tuple form of ToSocketAddrs, not format!("{host}:{port}"), which is ambiguous for IPv6 addresses returned without brackets by host_str(). Add IP-literal fast path that skips the OS resolver for bare IP hosts. - Add production-boundary tests: four HttpJwksFetcher direct-call regressions (http/credentials/fragment/private-IP) and two IPv6 SSRF fast-path tests (loopback rejected, public accepted). - Add tokio test-util dev-dependency to buzz-auth for start_paused.

Registry source: IANA IPv4/IPv6 Special-Purpose Address Space (registries last updated 2025-10-09, retrieved 2026-08-31; URLs in source doc comment). - Implement the IANA deny/exception table: outer predicate denies ranges whose registry entry is non-global or blank; explicit globally-reachable exceptions carved out inside otherwise-denied envelopes. IPv4 embedded in IPv4-mapped, IPv4-compatible, NAT64 well-known (64:ff9b::/96), and SIIT IPv4-translated space is evaluated recursively against the IPv4 table — registry global=True on the IPv6 wrapper does not bypass the embedded-address check. - IPv4: add 192.0.0.0/24 IETF Protocol Assignments (global=False) with globally- reachable exceptions 192.0.0.9 (PCP anycast, RFC 7723) and 192.0.0.10 (TURN anycast, RFC 8155); add 192.88.99.0/24 deprecated 6to4 relay anycast (global=None — conservative posture: block). - IPv6: replace individual Teredo/benchmarking/ORCHID checks with the 2001::/23 IETF Protocol Assignments envelope (global=False). Globally-reachable exceptions inside the /23 are allowed: 2001:1::1/2/3 (PCP/TURN/DNS-SD anycast), 2001:3::/32 (AMT), 2001:4:112::/48 (AS112-v6), 2001:20::/28 (ORCHIDv2, global=True), 2001:30::/28 (DETs, global=True). Add 100:0:0:1::/64 dummy prefix (RFC 9780), 3fff::/20 documentation (RFC 9637), 5f00::/16 SRv6 SIDs (RFC 9252). 2001:db8::/32 (outside 2001::/23) remains a separate check. - Consumer audit: buzz-workflow (CallWebhook) and desktop link_preview use the is_private_ip alias; the stricter predicate closes all new ranges for both callers. Cancellation-safe refresh permit (buzz-auth): - Per-issuer OwnedMutexGuard spans the complete fetch and state commit; cancelled callers release the permit on drop — no manual flag to poison. - ScriptedFetcher replaces BlockingFetcher + SequencedFetcher: a VecDeque of FetchStep{entered, release} makes call order self-documenting without comments. - concurrent_refresh_coalesces_without_second_fetch: entered barrier proves permit ownership before the second call; assert call_count == 1. - aborted_first_caller_releases_permit_for_next_caller: pending_step returns the release sender, which is held until after abort — task is genuinely blocked (not resolved via error path) when cancelled. assert call_count == 2. Central invariant regressions (buzz-auth): - expired_snapshot_never_served_after_hard_deadline: hard-deadline expiry closes both the async and synchronous snapshot paths. - two_issuer_keys_and_generations_are_isolated: advancing A's document advances A's generation only; B's key binding and generation are unchanged. Architecture docs (ARCHITECTURE.md): - Update is_private_ip function-table entry to is_not_global_unicast with compat alias. - Rewrite SSRF Protection section: deny/exception-table framing, embedded-IPv4 recursive evaluation, all three audited callers.

charset=UTF-8 Content-Transfer-Encoding: 8bit Implement the Design-B atomic orchestrator for NIP-FI kind-9 channel admission. A single SERIALIZABLE transaction spans enrollment, replay claim, receipts, epoch/fence, re-fence, and event insert (FI-INV-09). ## Changes ### buzz-auth - AssertionPolicyId::for_test and TransportContractId::for_test gated on `any(test, feature = "test-utils")` (was `cfg(test)`-only), enabling cross-crate integration test access. - VerifiedAssertion::test_support and minimal_verified_assertion similarly gated on the new test-utils feature. ### buzz-relay / nip_fi - Design-B atomic orchestrator: commit_kind9_atomic opens one SERIALIZABLE transaction spanning commit_admission_in_tx + authorize_protected_use_in_tx + Db::insert_event_with_thread_metadata_in_tx. All authority mutations and the event insert commit or roll back together. - commit_admission_in_tx signature changed to accept fresh_assertion: &VerifiedAssertion directly (no verifier param). Revalidate_assertion moved to commit_kind9_atomic before the transaction opens, keeping JWS round-trips out of the tx boundary and making the inner function testable. - revalidate_assertion promoted to pub(super) for use by the nip_fi orchestrator. - seal_inline visibility tightened pub(crate) → pub(super), restricting SealedRequestContext construction to nip_fi/mod.rs only. - imeta validation (validate_imeta_tags / verify_imeta_blobs) moved before commit_kind9_atomic call; invalid imeta can no longer commit authority state. - authorize_protected_use_body: added binding_id and policy_revision comparison against CommittedAuthorization; rows_affected() != 1 guards on both epoch and POA UPDATEs return AdmissionError::Transient on zero-row match. ### buzz-nip-fi-seal-test - Replaced three redundant compile-fail fixtures (all testing the same outer module-privacy wall) with two distinct fixtures: - context_sealed_from_external: outer wall; SealedRequestContext not reachable - authority_output_opaque: admission function boundary; different symbol path - Updated seal_boundary.rs documentation to explain the pub(super) contract. ### Production-path PostgreSQL witnesses (four #[ignore] tests) - pg_admission_and_protected_use_success: full Design-B path commits, POA row exists after commit. - pg_event_insert_failure_rolls_back_authority: FK violation on event INSERT causes rollback; no replay claim and no epoch row are committed (FI-INV-09). - pg_epoch_update_zero_rows_is_transient: epoch row deleted before authorize_protected_use_in_tx; rows_affected() guard returns Transient. - pg_poa_update_zero_rows_is_transient: POA row deleted before authorize_protected_use_in_tx; NoActiveBinding or Transient proves guard chain. All witnesses call through the production functions commit_admission_in_tx, authorize_protected_use_in_tx, and sqlx directly (no fixture-SQL stubs).

An advanced lifecycle between admission and final use could be silently accepted. Now compared; mismatch returns BindingRetired. 2. rows_affected() guards: both epoch and POA UPDATEs in authorize_protected_use_body already had rows_affected() != 1 guards returning Transient (present in the original PR4 commit). 3. compile-fail fixtures: both prior fixtures failed at the same outer module wall (mod nip_fi is private) — widening seal_inline from pub(super) to pub(crate) while keeping nip_fi private would not make either fixture turn green. Fixtures now explicitly name the layered boundary (outer wall + inner constructor + field-level opacity) with comments documenting what change at each layer would cause a turn-green. Seal boundary documented to explain trybuild's external-crate limitation and why pub(super) on seal_inline is separately enforced intra-crate. 4. connection.rs test helper: test_conn_with_auth was missing nip_fi_assertion and nip_fi_proof_meta fields in the ConnectionState struct initializer, causing a compile error in the merge-main worktree. Added both with correct zero-value defaults (None / OnceLock::new()). New named PostgreSQL mutation red: - pg_lifecycle_revision_advance_is_binding_retired: runs admission to record binding_lifecycle_revision=1, advances the row manually to simulate a concurrent transition, then asserts authorize_protected_use returns BindingRetired (proving the guard fires at the right error).
