Artifact publishing can attach a template, picking "workshop" automatically, but the gate defaults off.

What

The publish payload gained an optional template field that is only sent when the gate is on.

Details
  • Gated on tengu_amber_quill_moth, in-source fallback false, so this is off in this build unless remote config turns it on.
  • When enabled and no explicit template was given, the publish path picks "workshop" if a workshop surface is detected.
  • Separately and ungated: a new auto_edit_attribution field (thread_id / comment_id) is sent whenever present, and forces a base-version check the same way composed PR review does.

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

Feature flag
tengu_amber_quill_moth Off by default, switched on for this account

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

Read once, for one account on one subscription tier, against v2.1.221. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns on for tengu_amber_quill_moth, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
