A claimed slash command consumed only the text half of the composer
submission: /goal with reference images executed, cleared the draft, and
silently stranded the images in the rail. Model-visible attachment intent
had no route through the command plane.
The submission envelope is now modeled end to end. CommandDefinition
input.images declares acceptance; the declaration rides the descriptor to
every client, onto the minted CommandClaim, and into the input machine's
claim snapshot. commands.execute carries the submission's base64 images
and enforces the declaration in the executor: non-declaring commands, a
missing attachment store, and exceeded batch limits settle as logged
error results before the handler runs. Admission reuses the attachment
package's new admitEncodedImages, extracted from api-proxy's prompt path
so both wire endpoints share one limits/validation/commit sequence.
Producers own model visibility: /goal submits one user followup (image
blocks + a fixed reference line) after a successful create/edit so goal
rounds read the images from session history; /plan folds them into its
steered message. Grammar misfits (/goal pause, bare /plan, /plan off)
return direct errors and the composer keeps the images.
On the client, enter adjudication carries a SubmitEnvelope and every
command route that cannot consume images throws a localized refusal that
renders as one composer notice with draft and images retained; the
claimed pre-gate applies the same copy. An accepting claim serializes the
draft images, forwards them to commands.execute, and clears plus releases
them only on a success outcome.
The assembled web test roster gains the ui-input-trigger and ui-commands
plugins, mirroring the shipped composition, so slash submissions exercise
the command plane; a new keyless snapshot pins the refusal banner and the
accepting /goal flow over the built client graph.
- wire the directory pick's continue flag through InsertTextRequest to the
input shell, which re-tracks at the caret so descent reopens completion
(the flag was produced and forwarded but never consumed)
- guard the image-only send against a second Enter during the Host round-trip
- keep text appended after the sent snapshot when a submit settles ok; only
interleaved edits clear with the committed content
- drop the dead restoreImages left from the sink rewrite
- read recall labels through a shared defensive sessionRecallLabels helper
instead of unchecked casts over durable log data, and take the reference
summary separator from the locale dictionary
- align the composer specs merged from master with the transactional submit
contract (sinks resolve SubmitOutcome, settlement is awaited, call
assertions carry the AbortSignal), and restore master's forms where the
divergence served nothing (queue-mode sink case, single-line filter
expectation, component-identity slot lookup)
