DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Artifact database reports a rejected session credential

Not switched on
Useful1 Signal3
Artifacts not in their notes

A rejected artifact credential now reports a distinct "report this" outcome rather than a permission answer.

The artifact database is behind CLAUDE_CODE_ARTIFACT_DB or a gate that falls back to false.

Feature flag
tengu_umber_lattice Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.228: on

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.228. It isn't a statement about your account. What a flag value here can and cannot tell you

CLAUDE_CODE_ARTIFACT_DB
What

A 403 with a recognised body from the artifact database now produces a distinct outcome, credential_rejected with reason custody_403, classified as unavailable. Its explanation states this is a client/server integration fault to be reported, not an answer about whether the artifact exists or whether you may see it. The artifact database itself is behind the CLAUDE_CODE_ARTIFACT_DB environment variable or the tengu_umber_lattice gate, whose fallback is false.

Evidence

the server refused this session's credential at the artifact-db door, credential_rejected

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
