- Rewrite the 08-04 gutter-reservation note in place: the reservation is Chat's alone and the overlay branch points to the seat-width compensation note; the Testing section now describes the uncompensated control.
- Cross-reference the earlier rejection of the seat inset in the 08-12 note and record the engine-resolved-vs-fixed-8px drift as accepted residual cost instead of asserting Firefox resolves 8px.
- Pair --dsh-scrollbar-width with the mirrored ::-webkit-scrollbar rule and the compensation consumer in the scrollbar-styles gate; document the variable in the ui-theme README.
- Rename the e2e control to compareTabsWithoutCompensation and correct the vacuity-guard comment; rewrap the WorkspaceBrowser doc comment.
The flat-list ordering change duplicated the document-level native-drag
acceptance effect and the status-dot block across the search and session
rows, tripping the duplication gate. Extract useNativeDragAcceptance and
SessionStatusDots so both call sites share one implementation.
The locale plugin's inject list gained 'remote' and 'settingsScope' on
2026-08-10, but the built-bundle harness mounted it without providing
those services, so the locale fiber never started and the trajectory
plugin's apply never ran — the ring assertion saw no 'trajectory' entry.
Provide the same stubs ui-layout's apply bench uses.
Re-record the sidebar regions that the redesign intentionally changed:
group session counts are gone, search is a collapsed header action, and
grouping lives in the View options menu. Session rows also follow the new
recency ordering, so their tree order updates with the counts.
The sidebar redesign removed group session counts, collapsed search into a
header action, and moved grouping into the View options menu. Update the
browser scenarios that waited on the old surfaces:
- Wait on the Ungrouped bucket row instead of the removed session-count text.
- Expand the collapsed search control before filling the renamed input.
- Open the View options menu instead of the removed Group by button.
- Assert the persisted grouping under the new dsh.workspace.view.v4 key.
- built-boot: assert the fixture workspace group row instead of its count.
The export ZIP now carries every image any included log references under
media/<attachmentId>.<ext>, read and verified from the attachment store with
one entry per shared image. The endpoint requires the attachments service
alongside persistence and session-query; a referenced image that cannot be
read fails the stream like a missing descendant.
Rescope nothing new: drop the needless async from the inherited readRaw
default (reject explicitly on abort), fix the void arrow shorthand in
downloadBlob, and share one revision-stable file-read loop between readRaw
and readPrefix in the JSONL backend.
Show the four toolbar terms in English even in the Simplified Chinese
dictionary, including their tooltips, aria labels, and the export failure
message, and update the pinned-zh specs to match.
The markdown raw-source tab becomes Raw and the message-origin tab becomes
Source, keeping the renamed identifiers, labels, and overview links in sync.
The locale plugin now derives its durable preference from a settings scope
bound to the connection service, so the trajectory benches provide a
connection handle before loading it.
The persistence subsystem page gains the SessionRawArtifact section (with a
type-equiv manifest entry and zh counterpart), and the README and Agent Note
describe the drain-based backpressure instead of claiming the archive never
accumulates.
The navigation-panes replay scenario clicks the trajectory toolbar export
button and asserts the real host-streamed download: filename, a single
session.jsonl entry, and byte-verbatim seed content. The toolbar golden
refreshes for the localized export button.
Toolbar strings route through the locale dictionary's standard t seat (the
export button no longer mixes languages in the English golden), exportLog
passes the response blob straight to the browser save instead of copying it
three times, the client id sanitizer rejects dot segments like the host one,
and the fixture stub comment no longer misattributes the 404.
Chunk boundaries never split a surrogate pair (a lone high surrogate
re-encodes as U+FFFD and silently corrupts the exported artifact), production
yields whenever the response queue fills so a slow consumer bounds the
accumulation, includeDescendants rejects values other than true/false instead
of silently under-exporting, the dead missing-services arm is deleted by
narrowing the streaming deps, and the readRaw failure answers 500 without
leaking host paths into the browser error bar.
The inherited readRaw default now rejects like the async backend overrides
instead of throwing synchronously, and its arms plus the JSONL override's
retry loop, zero-frame, and corrupt-header branches get dedicated tests.
The 导出 button fetches GET /api/session.export and saves the ZIP (root
artifact plus subagent descendants). The plugin exposes exportLog through
the view's inject face, resolves the tab label through the locale service,
and disables the button while in flight; fixture mode answers 404 so the
error bar explains the gap.
Streams one ZIP of the root session artifact plus each subagent descendant
verbatim (the persistence readRaw bytes) from GET /api/session.export as a
host-only download — no wire envelope, absent from IApiClient. The downloads
domain owns the query schema, the fetch handler answers the GET alongside the
SSE routes, and compression runs on the host with fflate's streaming Zip API.
The persistence contract gains a concrete readRaw default (undefined for
backends without a per-session artifact) and the JSONL backend overrides it
with the decode of its physical zstd frames, so a consumer can read the
stored artifact text verbatim — the session-log export depends on it.
