The write/edit tools already declare card:'diff' with applied hunks on
callView/resultView, but the Web client discarded it: a mutation landed on
GenericToolCard and the details panel flattened the result to a <pre>. Add
DiffBlock (ui-primitives), diff-card-model (the single callView/resultView
derivation), and FileMutationRow (keyed under write and edit), and make the
generic fallback row and the details panel diff-aware. The +/- block form,
per-file path header, same-file gap, and footer mirror the TUI diff card;
the chat row caps at CHAT_DIFF_MAX_LINES against the panel's full height.
fix(web): keep one composer bar DOM across the no-workspace transition
The composer.bar slot moves from session to session-maybe scope: with no
current session the entry still mounts, the machine faces (keyboard, stop,
command) arrive undefined, and the bar renders its normal DOM inert via the
disabled owner prop. DisabledInputBar and its parallel tree are gone, so the
textarea node survives the cold-start workspace pick instead of flashing
through a remount. A blank session whose workspace was deleted takes the
same inert path through owner props.
test(web): add the composer DOM-continuity acceptance probe
Drives a real dsh web server with headless chromium through the cold-start
-> pick-workspace -> type flow and asserts the composer textarea is the
same DOM node throughout (a marker property must survive). Rerun
prerequisites are in the header comment.
docs(web): session-maybe identity is adoption, not hold-forever
fix(web): session-maybe entries adopt the first session, then remount like strict entries
A session-maybe entry used to keep one React instance across every
transition, so component-local state leaked between sessions once the
composer bar moved to that scope (PermissionSelect's optimistic pick, the
IME composition guard). Identity is now adoption: an incarnation born
session-less holds through the arrival of the first session (the blank
shell's DOM survives the workspace pick), and afterwards behaves exactly
like a strict session entry — a switch or a drop to no-session remounts,
clearing local state by construction. The child key is an incarnation
counter kept in the stable outlet wrapper via render-phase setState.
chore: knip knows the root acceptance probe's playwright dependency
scripts/hero-composer-dom-continuity.mjs resolves playwright through
apps/web's devDependency tree (createRequire), which knip cannot follow;
ignore it at the root workspace.
The chat stats line took its token totals from the loaded conversation nodes,
so paging changed them and compaction erased the billing behind replaced
content. It also had no way to show context occupancy: the numerator and
capacity never reached the browser.
Both now come from token-meter session projections read through the standard
useProjection seat. Window nodes keep supplying turn and step counts plus LLM
and tool wall times, which are correctly window-scoped facts about what is on
screen; accounting no longer comes from there.
`tokenUsage` supplies billing and cache hit. `contextPressure` supplies
occupancy, pairing the newest provider-reported prompt size with the newest
capacity recorded by `request/context`. Deployments without token-meter drop
the token groups; a route whose adapter advertises no capacity drops the
occupancy group rather than rendering a placeholder.
Occupancy is deliberately approximate: the numerator and capacity are
independent last-wins fields, not one atomic request observation, so switching
models pairs a fresh capacity with the prior route's pressure until the next
request reports usage. It is a user-facing reference figure that nothing in the
harness makes decisions from, and it matches how the TUI status line has always
computed occupancy. The Agent Note and token-meter README state this as a
decision, including why the atomic alternative was implemented and rejected, so
it is not re-litigated as a defect.
Snapshot delta is one added `Context N% of 128K` segment across eight web
goldens; the preceding commit absorbed master's pre-existing golden drift.
Conflict resolution notes:
- StatsLine: master redesigned the row into pipe-separated groups with LLM and
tool wall times. Kept that design and swapped only the token accounting
source, so counts and durations stay window-scoped while billing and context
occupancy read the durable projections.
- Generated artifacts (cordis catalog, module graph, event producer/consumer,
i18n pairing hashes) and web snapshots took master's side; they are
regenerated and re-recorded after this merge.
- Web e2e goldens and details-panel/timeline assertions took master's side:
that evolution is unrelated to this branch.
- ui-conversation package.json: kept master's devDependency ordering, re-adding
only the token-meter entry this branch needs.
Stats line moves into the InputBar's new footer slot (sharing the card's
width column) and expands to the design's grouped detail row: turns/steps,
LLM and tool wall time, cache hit, and input/output token split, all
derived client-side from the snapshot. The composer stack owns one 8px
rhythm, the seat fades the transcript through a fixed 36px gradient band,
back-to-bottom follows a live --dsh-composer-height, and goal/todo strips
share one 752px tip-fill column.
Update the six touched client package README pairs (slash menu ordering,
localized group titles and dismiss, permission label twin, goal pause,
plan hint localization, useAnchoredMaxHeight) and keep the owning agent
notes current: SlashSource.order and the MenuView dismiss/localize/clamp
face in the slash-pipeline note, the pause verb in the goal bar note.
