AgentAdmissionRejected now extends HarnessError with the fixed code
AGENT_ADMISSION_REJECTED. The Session Remote recognizes a refusal by that
code and imports only agent-controller types, so its mapping also holds for
an error from another copy of the module; its literals are typed by the
agent-controller constants, so a changed value fails the build.
Fold room takes output growth before any scroll, like the empty space below content that fits, so the tail is pinned only when no room remains.

A row whose ancestor finished closing sits under hidden="until-found", which keeps its own size but removes it from the flow. Finish such a row instead of driving it in a second batch that scrolls the view for content that occupies no space, and release held reveals when no closing member remains.

Describe async generator yields, key-conflict reads, and macrotask timing as implemented, restore the API controller and mods bridge sentence in the upgrade guide, record the rejected plugin-disposal alternative, and pin the async generator behavior with a test.
Record the deprecated registration and keyed-read compatibility in the retained-reader decision instead of a separate note, and remove the 2026-10-19 compatibility note.
A legacy plugin may store the registration result as a disposer or ignore it,
so a failed registration became an unhandled rejection that ends a dsh process.
The registry now attaches its own handler: once the current turn ends, a
rejection nobody observed through then/catch/finally is logged through the
calling plugin's logger while the plugin stays active, and one whose owner is
no longer loading or active is dropped. Observed rejections are unchanged.
- register() returns the registration's effect disposer with then/catch/finally
attached; the original body moves unchanged into a private acquire(), keeping
synchronous installation and the asynchronous handle handoff.
- Legacy stateOf(session, key) logs one ctx.logger.warn per key per registry;
registration and calls to its result no longer warn.
- Containing an ignored legacy registration failure is deferred and recorded
under Known Limitations.
Move the session projection handles guide from the released v0.2.1-alpha.3
directory to the current v0.2.1-rc.2 directory and fold in the callable
registration and deprecated keyed-read notes, replacing the separate
session-projection-registration guide.
