Propagate suppressError to the default document loader. The generated accessor calls documentLoader(lookupUrl) at packages/vocab-tools/src/property.ts:92. The default loader reaches getRemoteDocument, which logs non-OK responses at error level before throwing FetchError. The accessor then catches that error and returns null when suppressError is true. Make the loader logging suppression-aware, while preserving error logging and throws for unsuppressed calls.

Thanks for pointing this out. I confirmed that the default document loader logs a non-OK response at the error level before throwing the FetchError that the generated accessor suppresses. (packages/vocab-runtime/src/docloader.ts: line 188, source)
Addressing this would require propagating suppression through DocumentLoaderOptions and getRemoteDocument(), which expands the change beyond the two generated accessor catches identified in #933. Would you prefer that propagation to be included in this PR, or should this PR remain scoped to the accessor-level logs described in the issue?

@Lumia1108, please include the propagation in this PR.
The current accessor-level change does not prevent error-level logging when the default document loader fails. That path is within the stated objective because suppressError: true intentionally absorbs the same FetchError.
Keep the change limited to forwarding the suppression state through DocumentLoaderOptions and getRemoteDocument(). Preserve the existing error-level log and thrown exception when suppressError is absent or false. Add coverage for a non-OK default-loader response with suppressError: true.

Please pass the suppression state through to the document loader in this PR. With a mocked HTTP 404 response, Announce.getObject({ suppressError: true }) returns null, but the default document loader still emits an error-level log before the accessor catches the exception. This leaves the error-reporting problem unresolved for HTTP failures.
Pass the suppression state through the loader path so these failures log at warning level while still throwing for the accessor to handle. Preserve the existing error logging and exception behavior when suppressError is absent or false. Please add regression coverage that captures logs for suppressed fetch and parsing failures and checks that unsuppressed calls still throw.

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!

Sorry for the delay in reviewing this. Please address the comments and rebase your branch onto the latest upstream main to resolve the conflicts. Please use rebase rather than merging main into your branch (cross-merge).

Please use .warn() in both catches, as proposed in the issue discussion. These suppressed failures should remain visible for diagnostics without being treated as application errors. Using debug hides them when an application collects only warning-level logs and above. Please update the three runtime snapshots and the changelog to match.

Summary
Vocabulary accessors currently log fetch and parsing failures at the error level even when callers explicitly enable
suppressError. This can cause intentionally handled failures from untrusted remote objects to be reported as application error events.This change lowers those logs to the debug level while preserving the existing
nullreturn value. Calls withoutsuppressErrorcontinue to throw the original exception.Closes #933
Testing
mise run test:deno packages/vocab-tools/src/class.test.tsmise run check-each vocab-toolsmise run test-each vocab-toolsAI assistance
Codex (GPT-5.6) was used to understand the issue, compare the appropriate log levels with existing project conventions, review the implementation and generated changes, and provide guidance for testing and the contribution workflow.
I personally made the source change, regenerated and reviewed all three runtime snapshots, reviewed the changelog changes, and independently ran the focused Deno test and the final package checks listed above. I verified that the generated changes only lower the two suppressed failure logs from error to debug level.
