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.

Session naming has explicit outcomes when two sessions want the same name

Not switched on
Useful2 Signal3
Cross-Session Messaging

Two sessions wanting the same name now resolve through fixed outcomes deciding who keeps or yields it.

Session name-claim outcomes are built out but availability is set by remote config.

What

Claiming a session name now resolves to one of a fixed set of outcomes ("own-name", "held", "yielded", "kept", "superseded", "pre-decided"), and that outcome decides whether the name is recorded as user-chosen, auto-generated or a collision, whether the session announces that it gave the name up, and whether the old name is kept for the session list. Part of the cross-session naming machinery, whose availability is set by remote config.

Evidence

pre-decided

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