Added tests for audio/video rejection. C2: Remove DocumentSource.URL field — it was Phase 2 only and carries dead code. Deleted entirely from DocumentSource. C3: Add 10s timeout to context in modelcaps.Load and LoadFromStore. Falls back to conservative text-only caps and logs a warning on timeout or fetch failure. C4: Switch anthropic/attachments.go from Beta SDK types to standard (non-beta) Anthropic SDK types: ImageBlockParam, DocumentBlockParam, TextBlockParam, ContentBlockParamUnion. The beta SDK is not needed for document conversion since we are not using the Files API. C5: Wire MessagePartTypeDocument into non-beta convertUserMultiContent in anthropic/client.go so documents are handled on the standard path. Updated convertBetaUserMultiContent to call convertDocument and convert standard → beta blocks via new stdBlocksToBeta helper. golangci-lint: 0 issues. All tests pass.

The isKnownDocMIME unconditional allowlist was wrong. Changes: - Remove unconditional Office MIME allowlist from Supports() - Rename helper to isOfficeMIME() (now returns false from Supports()) - Office MIMEs now return false for all models because models.dev only exposes: text, image, pdf, audio, video modalities — no document/office field exists yet. Conservative fallback until models.dev schema adds it. - Updated TestLoadFromStore_OfficeDocsAlwaysAllowed -> NotAllowed - Updated decide_test.go: office doc case now expects StrategyDrop - Extended TestSupports_AudioVideoRejected to also cover Office MIMEs The forward-looking officeDocumentFormat() in bedrock/attachments.go is retained — it will activate once models.dev adds an office/document modality.
