Authenticate actorless FEP-7aa9 requests against the owner of the referenced collection, then use that owner as the actor passed to the listener. Preserve the signed document and carry the authenticated owner through queued processing and retries. Keep transient collection lookup failures retryable, and reject the activity on permanent failures. Add regression coverage for HTTP Signatures, Linked Data Signatures and Object Integrity Proofs, mixed signatures, forged ownership, queue retries and lookup errors.

Discard the inferred FeatureRequest owner when HTTP authentication reparses the activity. A changing context loader can select another instrument, so resolve the final collection owner before checking the HTTP signing key. Cover this mismatch with a regression test. fedify-dev#1291 (comment) Assisted-by: Codex:gpt-6.1-sol
Retain retryable loader failures across WebFinger fallback attempts. Only discard them after finding a FeaturedCollection with the requested ID and one owner, so later permanent errors or invalid objects cannot hide a temporary outage.

Store the collection ID alongside the inferred FeatureRequest owner. Reject replay when parsing changes the instrument, actor presence or activity type, rather than delivering an owner authenticated for a different collection. Preserve the original payload and queue retries. fedify-dev#1291 (comment) Assisted-by: Codex:gpt-6.1-sol
A parsed actorless FeatureRequest with no proofs is not authenticated. Require a verified document signature before resolving its owner, or fall back to HTTP authentication first. Keep explicit verification bypass behavior and cover unsigned requests with a no-lookup test. fedify-dev#1291 (comment) Assisted-by: Codex:gpt-6.1-sol
Resolve web collection IDs through the document loader directly. WebFinger's best-effort account discovery hides failures and should not decide collection authorization. Classify the authoritative fetch failure instead, while retaining verified lookup for portable IDs. Replace account-fallback tests with checks that a collection 404 does not trigger WebFinger even when that service is temporarily unavailable. fedify-dev#1291 (comment) Assisted-by: Codex:gpt-6.1-sol

Treat known parsing and validation failures from collection loaders as permanent invalid input, preserving that classification when JSON-LD wraps the original error. Malformed collection responses must return 400 rather than escape as retryable server errors. Keep network and unknown loader TypeErrors retryable, along with DNS failures, HTTP 408/429, and server failures.

Reuse the inbox's temporal-literal validation at the web collection parse boundary.

Reject usernames and passwords in a collection URL before calling its loader.

Exercise credential-bearing FeatureRequest instruments after HTTP, Linked Data Signature, and Object Integrity Proof authentication. Check that the inbox returns 400 without notifying listeners or loading the collection, rather than relying only on direct resolver tests.

ID accessors and typed parsing omit anonymous attribution values. Require one full value before inferring the FeatureRequest owner. Expand web collections once and parse that same view so validation counts values that the typed parser would otherwise discard. Regressions cover both orders of anonymous values and all authentication mechanisms, including untyped values from the remote collection. fedify-dev#1291 (comment) Assisted-by: Codex:gpt-6.1-sol
Treat returned 3xx FetchErrors and Node's credential-URL construction error as permanent collection failures rather than retrying malformed remote data. Check returned document URLs too, since Deno and Bun can construct credential-bearing Requests.

Both built-in document loaders report redirect loops and exhausted redirect limits as FetchErrors without responses. Recognize those known failures so actorless FeatureRequests reject unusable collection lookups instead of retrying them. Other response-less failures remain retryable. Regression tests exercise HTTP and alternate-document chains through both loaders with HTTP, LDS, and proof authentication. Additional cases preserve timeout retries and cover Node's credential-URL error. fedify-dev#1291 (comment) Assisted-by: Codex:gpt-6.1-sol

An empty actorIds list can hide anonymous actors, blank nodes, and untyped values. Reject these explicitly declared actors rather than replacing them with an inferred FeatureRequest owner. Record contexts from the current parsing attempt and check actor presence against that input view without re-fetching mutable contexts. Reset the captured view on HTTP fallback and owner-proof retries. fedify-dev#1291 (comment) Assisted-by: Codex:gpt-6.1-sol
allowPrivateAddress bypassed protocol validation along with address checks. Reject unsupported schemes in both built-in loaders before fetching initial URLs, redirects, or alternate documents.

Fresh evidence beyond the earlier instrument-cardinality fix is that this round-trip counts only values retained by the generated decoder, not all values in the authenticated source. For a signed instrument: [{"name":"anonymous"}, collectionUrl], the untyped first node is omitted by the Object decoder, so both instrumentIds and request.toJsonLd() contain only the URL and this request is accepted despite declaring two instruments; preserve and count the authenticated source expansion instead of reconstructing it from the typed instance.

Fresh evidence beyond the earlier temporal-field fix is that a changing remote context can make this diagnostic inspect a different document from the one that failed: if the first collection expansion maps an alias to malformed published or duration, ActivityObject.fromJsonLd(expandedCollection) throws, but this call re-expands collectionDocument through the live loader, whose next response can remap the alias. The helper then returns false and the RangeError is rethrown as a retryable 5xx; inspect the already-populated expandedCollection so the malformed sender-controlled view remains a 400.

When an authenticated sender serves a FeaturedCollection with an embedded DataIntegrityProof whose proofValue uses an unsupported multibase prefix, the generated decoder calls decodeMultibase(), which throws a plain Error (packages/vocab-runtime/src/multibase/mod.ts:49-66). No wrapped loader has failed and this predicate recognizes neither that error nor the malformed proof value, so this rethrow turns permanently invalid sender-controlled data into a 5xx/retry loop rather than the established 400 response; positively classify malformed multibase proof/key fields as permanent.

Fresh evidence beyond the earlier attribution-cardinality fix is that the portable-ID branch never records the source expansion in expandedCollection. If a verified portable FeaturedCollection contains raw attributedTo: [{"name":"anonymous"}, ownerUrl], lookupObject()'s typed decoder omits the untyped value and this serialization reconstructs only ownerUrl, so the one-owner check passes and an owner-signed request is accepted despite the collection declaring two attribution values; carry the source expanded cardinality through portable lookup rather than deriving it from the lossy typed object.

Mastodon's FEP-7aa9 requests omit
actor, so the inbox rejects them before listeners run. The inbox now resolves the referencedFeaturedCollectionindependently and requires its owner to match a verified document signer or HTTP signature key owner. This prevents a signed request from claiming someone else's collection.The inbox uses the authenticated owner as
actorin the parsed activity and preserves the original signed payload. Queued processing retains that owner, so retries need not fetch the collection again.The exception applies only to
FeatureRequest, keeping the maintenance patch narrow. Shared inbox authentication is deferred to #1290.Fixes #1289.
