Single-click original preview in the composer rail and chat history; remove
control inside the thumbnail, revealed on hover/focus (always on touch);
hidden-scrollbar rail overflow paged by edge arrows with wheel panning and
end-reveal on add; image-intake rejections and prompt failures announce as a
transient top-center toast instead of inline strips.
The attachment atoms move to a new zero-cordis package
@deepseek-ai/dsh-client-ui-attachment (rail, message gallery, lightbox),
seeded as a platform module; the toast is a ui-primitives atom. Strings
arrive as label props bridged from the conversation dictionary.
Session-log ZIP entries always used DEFLATE level 6 even though compression level is a deployment tradeoff: CPU-constrained hosts may prefer low latency while bandwidth-constrained hosts may prefer smaller archives. A hardcoded level also violated the repository rule that deployment-varying plugin choices live in validated Config.
Add sessionExportCompressionLevel to ApiProxyService.Config as an integer 0-9 with default 6, resolve the same default once for direct createApiProxy callers, and pass the required level into the streaming module. Tests prove schema defaulting and rejection as well as a level-0 versus level-9 archive-size difference with identical extracted content. The generated config catalog, bilingual gateway README, and feature note document the knob and its tradeoff.
The ZIP loop checked desiredSize only after a push and responded to an overfull queue with setTimeout(0). A timer turn does not mean the consumer drained anything, so a slow or disconnected client still allowed the producer to enqueue the complete compressed archive while later artifact and attachment reads ran eagerly.
Give the ReadableStream a 64 KiB byte queuing strategy and block the single producer on a pull-released capacity gate whenever desiredSize is non-positive. Cancellation wakes that gate through the existing producer signal; synchronous fflate output is therefore bounded to the queue high-water mark plus one input push. A regression test exhausts timer turns without consuming and proves the next media entry remains unread until response pulling begins, and the bilingual contracts now describe the real bound.
Only the root raw-artifact read received the request signal. Lineage discovery and descendant reads could continue after disconnect, response-body cancellation did not stop the producer, and the root error boundary converted an abort rejection into an ordinary HTTP 500.
Combine request and response-consumer cancellation into the ZIP producer signal, forward it through every cancellable read, check it around the attachment seam, and terminate fflate exactly once when production stops. The pre-stream boundary now rethrows the original abort instead of translating it. Regression tests cover signal propagation, exact cancellation identity at the HTTP boundary, and a reader cancellation interrupting an in-flight descendant read; the bilingual host contract records these lifecycle semantics.
The exporter read persistence artifacts directly even when the requested root or a descendant was still live. Buffered session events could therefore be omitted from a successful download, so the advertised verbatim-artifact guarantee described storage accurately but captured an arbitrarily stale durability boundary.
Resolve each id against SessionStore and cross its authoritative flush barrier immediately before readRaw. Cold sessions remain a no-op, while live roots and descendants are made durable independently; this intentionally yields a per-session read-boundary snapshot rather than claiming an atomic lineage snapshot. A host-path regression test proves both artifacts change from stale to durable only through flush, and the bilingual host contract and Agent Note document the boundary.
Entry \disabled\ interpolation makes the launcher's separate platform layer
unnecessary: the base bundle's cordis.patch.yml now gates both shell stacks
on its own rows — bash-sandbox/tool-bash disable on win32, and their twins
pwsh-sandbox/tool-pwsh mount only there with the inverted expression — so
exactly one shell stack mounts per host from one shared patch file.
windows.cordis.patch.yml and the launcher's windows-shell.ts injection (boot,
live recomposition, config dumps) are deleted, with the workspace-constraints
entry and the dsh-base exports/files entries following. The windows-shell spec
pins the effective per-platform roster through the real bundle layers, and
base.spec pins the four symmetric gates. The superseded active notes are
updated and cross-linked; the loader note records the fold itself.
A present zero-byte .jsonl.zstd file was treated as though no artifact existed because readRaw returned undefined when frame scanning found nothing. That contradicted both the plaintext path and the logical zstd reader, and it made the export endpoint answer 404 for on-disk corruption.
Treat a present artifact without a complete header frame as corruption and reuse the zstd reader's existing diagnostic. The regression test now distinguishes an existing empty file from an absent path, and the bilingual JSONL storage contract records that zero-frame artifacts reject alongside other header and frame failures.
SessionPersistence.readRaw previously used undefined for two unrelated states: a supported backend could not find the requested session, or the backend had no per-session artifact concept at all. The export endpoint consequently reported an existing SQLite-backed session as HTTP 404, which falsely diagnosed storage capability as session absence.
Make raw-artifact support an explicit backend capability. Unsupported backends now fail their inherited readRaw path loudly and the host answers 501 before reading, while undefined retains the single meaning of an absent artifact on a supporting backend. First-party backends, test providers, generated API catalogs, bilingual persistence docs, and export error contracts now state that distinction; focused tests cover both the 501 and the inherited rejection.
The export endpoint already streams a ZIP response, but the web client immediately converted that response into a Blob. That forced the complete archive through JavaScript memory before a download could start and coupled transport, buffering, object-URL lifetime, and filename handling to the trajectory view.
Navigate a temporary download anchor directly to the export endpoint instead. The browser now owns streaming and HTTP failure presentation, while a standalone delivery module owns URL construction and filename sanitization. Focused tests cover the handoff, rejection behavior, and the assembled session view; the package README and feature note record the new ownership boundary.
Only `docs/module-graph.*` conflicted; generated, so taken from master and

Hook bypassed as before: the staged-pairing check hands an archived note path

The bubble clamped horizontally and did nothing vertically, so a long
label under an anchor low on the page ran off the bottom. Preset cards
made that the common case: custom presets sit at the end of the roster
and carry the longest descriptions.
A `top` or `bottom` bubble now flips to the other side, and only into a
side that genuinely fits — an anchor with room on neither keeps the
requested placement rather than oscillating. Sliding the bubble
vertically instead would cover the text being read.
Only `docs/module-graph.*` conflicted, from master's new

Hook bypassed as before: the staged-pairing check hands an archived note path

A preset publishes its own description, of any length, and `.cards` sizes
rows with `grid-auto-rows: 1fr` — which makes every implicit row the same
height, not just the row holding the tall card. One long description
therefore set the height of the whole roster.
The description now clamps to four lines and offers the rest through the
shared Tooltip, attached only while the element actually overflows. Card
height stays derived: with the description bounded, `grid-auto-rows: 1fr`
already equalizes, and a card carrying the broken-preset reason or a
revealed path still sizes itself.
Tooltip gains an optional `maxWidth`; its default half-viewport cap
renders a description wider than the settings dialog it belongs to.
The failed-shape-check badge reads "Failed to load" rather than "Broken":
discovery reports a composition that is missing, unreadable, or malformed,
which overstates as damage.
Fixes#2238
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.
