A readable V3 child may have no own descriptor, an unknown descriptor version,
or multiple descriptors. Those states do not provide a unique discovery fact,
but they do not make the parent or the retained child history unreadable.
Rejecting the entire parent prevented otherwise valid V3 Sessions from opening.
Append a missing parent catalog row only for exactly one supported own child
descriptor. Keep existing parent entries and every child record when no fact is
available. Retain rejection of mismatched creation times, unambiguous mode/label
conflicts, malformed known fields, unreadable membership and revision drift.
Cover raw and compressed read/write publication, preserved source bytes, late
descriptor availability, inherited descriptors and Preview packing. Document
that unavailable discovery evidence can leave a child absent from its parent
catalog and does not trigger automatic backfill after the V4 successor exists.
Extracts the child-evidence behavior from 7ba7e174dd1 and the Preview regression
from 9c85eb60bd25, preserving the original migration authors' work while keeping
message representation and extension interpretation outside this commit.

Merge 3ea52fc3e475a3e7c430812bde4209258416e57b into a0a61a8237f61344a01448a97954df603d8fff73. Retain the V2-to-V3 migration dependency alongside native system flock support, removing the replaced fs-ext dependency. Union the lockfile workspace importer entries; frozen installation validates the result without regeneration.
Preserve release publint async lane-signal cancellation, close ownership, and spawn-error regressions, satisfying the incoming CI budget intent. Keep canonical, prompt, preset, and latest migration regression behavior. Rename an arbitrary preset fixture value to custom-agent to avoid the inherited vendor-rescope false positive without changing test semantics.
Validation: frozen install; full build including Darwin addon; focused V3/persistence/prompt/publint and runtime tests; built migration, two-process lease, and loader smokes; native flock and package-matrix tests; touched dependency and CI owner tests; all hygiene leaves (vendor residue repaired and rechecked); doc-sync 34/34.
Both coverage lanes now run before any build, so the post-build
uninstrumented gate wording applies only to the serial-windows complete
reference; preview builds still exercise the suite against real
artifacts.
A settled top-level `read_image` call printed its raw attachment object as
literal text in the tool card — `{"type":"image","attachment":{…}}` —
instead of the image, because no presentation metadata told a client card
how to present the reference and the tool-card layer had no image concept.
Host: `read_image` declares an `output.presentationMeta` persisting
`{ path }` only. The attachment reference deliberately lives in the
settled result content — the single record a `tools/post-execute`
replacement rewrites — not in `meta`; the id is opaque and
provider-owned, checked for existence only.
Client: `imageCardModel` derives the card from the call head, the meta
path, the result's own image block, and a shape-matched envelope. ToolRow
gains an `image` card slot; the `read_image` toolview declares the
Tool-owned `tool.call.images` slot as its child and dispatches the
gallery through it. ui-chat down-threads the session-authorized loader
(`ChatNodeOwnerProps.loadImage`), so the tool layer supplies only derived
references plus the loader and never imports an attachment
implementation; ui-attachment fills the slot with its message gallery
renderer. The card keeps the envelope text below the gallery for the
no-attachment-plugin deployment. An image-bearing tool registers a keyed
toolview; the generic fallback keeps its flattened text. `read_image`
joins the read variant with its own locale title key; both rows share
`read-family-row.tsx`.
Verification: `read-image.spec.ts` (metadata projection, envelope by
shape, reference narrowing, real-execution round trip, rejection
branches incl. non-digest ids), `image-card.client.spec.tsx` (derivation,
row render site dispatching the slot, keyed registration with the
child-slot declaration, empty-slot fallbacks, media-type enum), keyless
snapshots (`read-image-gif` added; read-image/-dimension/-reencode
updated to the `{path}` meta), five injected-defect negative controls,
and a demo GIF recorded from this PR's head through the official
image-capable model.
Two private experimental packages run the whole harness tree inside one
dedicated Web Worker. dsh-experimental-webworker-runtime owns the in-memory
VFS (BigInt stats with per-path identity and strictly increasing mtimes),
the CommonJS wrapper loader over a lazily-evaluated builtin table whose
shims typecheck against Node's own module types, the postMessage tunnel
speaking plain HTTP, the AsyncLocalStorage runtime, and the worker
assembly. dsh-experimental-webworker-packer lowers every module body at
pack time against the shared wrapper contract, sweeps the profile closure
by static reachability, and writes a deterministically gzip-compressed tar
the worker inflates through the browser's native DecompressionStream while
it downloads.
