Session candidates labelled from projection checkpoints instead of a full
log fold per keystroke, with the uncheckpointed remainder folded once and
memoized while its log stays cold. The file index keeps answering while an
invalidated traversal rebuilds behind the caret, and its default exclusions
now cover build outputs so deep sources stay reachable.
Rows carry only what distinguishes them: a file names its parent directory,
a session names its workspace only when that workspace is not the current
one, and a drilled listing names none because its new breadcrumb does.

A directory row in the @ menu had one verb doing two jobs: picking it
inserted literal @dir/ text and kept the menu open, so a user wanting
the folder itself never got a settled entity — the token kept its
trigger character and stayed editable, nothing like a file's atomic
chip.
Split the intents on the same row, mapped to shell-completion instincts:
row click / Enter settles the directory as an atomic folder chip (the
file chip's exact language; canonical @dir/ mention as its serialized
form — the { insert } arm the folder path never took), while Tab or the
row's trailing chevron drills: literal editable text, menu open on the
children. One new dimension carries it: candidate.drill advertises the
verb, InputTriggerPick.action reports it, ArbitrateKey gains 'tab', and
the keymap intercepts Tab only while a drill row is highlighted.
Covered by controller arbitration, MenuView chevron routing, the
ui-reference verb split, a keymap Tab-passthrough spec, and a real-
browser e2e driving all three gestures; menu golden refreshed for the
chevron and the fixture directory.
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.
