363db89ba removed the client-side modality gate and the tests that fed
host.describe a scripted activeModel, but left the fakeApi override
field, its ResponseValue import, and the ?? fallback behind. Nothing
passes hostDescription, so the left arm was unreachable.
- gate model selection on steering-placement image carriers from enqueue
until their steering/message event publishes; release the gate when an
admission ends idle without publication (both behaviorally asserted)
- reject session.updateQueue edits carrying non-text blocks at the RPC
boundary (queue edits cannot bypass image admission)
- extend the durable-directory walk past a first-created DSH_HOME to the
deepest pre-existing ancestor
- strip Windows-style separators from attachment display names on POSIX
- verify attachment reads with a header-only probe (digest already proves
the bytes decoded fully at admission); document the read path
- make SessionInputShell.addImages refusal observable and keep workspace
transfers/composer intake from leaking refused drafts
- own ONE recursive image walk (dsh-llm contentHasImage) across apiproxy,
pi-ai, compact-basic, and the DeepSeek text-only assertion
- drop the redundant canonical-base64 regex and the no-op role read
- move AttachmentId/AttachmentError out of types.ts (brand.ts/error.ts);
document why AttachmentError does not extend HarnessError
- document the hard attachments inject in both consumer READMEs
- `SessionSummary.updatedAt`'s wire doc still said "Persisted file mtime",
which stopped being true for attached sessions.
- The core invariant let `session/inherited` fall through the merge-extensible
default. It is core-owned, so it gets an explicit case; an unbalanced seed
legally places it inside an open turn, which the relation permits.
- The Agent Note claimed the boundary reaches disk via `live.pending`/
`scheduleDrain`. Verified false: the constructor append precedes `enter()`,
so it never publishes on `session/event` and rides the creation seed instead.
Attaching is therefore a write where none happened before — recorded, since
only `load()` stays a pure read.
- The deferred-index proposal asserted this change documented the cold-mtime
skew on `dsh-host-apiproxy`. It did not; the README entry now exists.
- `firstLiveSeq`'s firehose gap runs through its own seq, not below it.
- The boundary is not always at `firstLiveSeq` (the idempotence guard), so
consumers scan for the last one.
- `lastActivityTime` excludes by type, so a pickup time still leaks onto a
synthetic closer when a boundary ends an open turn. Documented.
- Pin the fork claim end-to-end: a child inherits a still-running parent's
open bracket below its own boundary, while the parent has none. Fails if the
write moves back to the load path.
- Fix the telemetry title that contradicted its own assertions.
The `/status` call site cannot be pinned the way the other two are: the
command appends its own `command/run` before rendering, so the boundary is
never the log tail there. Its fixture now at least renders over a
boundary-bearing log.
A plugin owning a standalone open/close bracket cannot tell a dead marker
from a live one: an unmatched `compact/start` reads identically whether the
previous writer died mid-compaction or a compaction is running now.
`Session.firstLiveSeq` already holds that answer exactly, but only in memory.
Append the log-only `session/inherited` event at that seq from the seeded
constructor — the single waist all six seeded-start paths pass through
(resume, configured startup on a persisted id, `sessions.fork()`, a subagent
fork child, `adopt()`'s live prefix, and a bare seeded `create`). Read it
through the new `isInheritedSeq(events, seq)`.
The constructor placement means persistence needs no changes: the marker is
already in `events` when a backend captures the creation seed, so it rides
the ordinary seed path with no load-time write. It also covers fork, where
the inherited bracket's owner may still be running — the case a
persistence-layer boundary could not reach.
Activity ordering excludes the boundary through `lastActivityTime()`, since
lazy resume makes browsing a pickup and the three call sites would otherwise
float every opened session to the top of a picker or list.
The rename impl narrows on SessionTitleInvalidError: only an
empty-normalizing title maps to title-invalid (its message renders verbatim
in the rename dialog alert), while liveness/disposal races fall to internal;
the absent-service message trims to one presentable sentence. rpc-schemas
gains the title-invalid accept/missing-details lines; cosmetic ordering
(type-only import comment, tsconfig reference, schema import order) restored.
- llm-deepseek: the uncatalogued resolveModel fallback declares text-only
modalities — the wire route is text-only regardless of catalog
membership, so "unknown" must not let the host persist-then-fail images.
- session.selectModel also consults the pending-inbox mirror: a queued
image prompt enters the log only when claimed, after a switch would land.
- attachment store: ensureDurableDirectory syncs every ancestor entry up to
a caller-vouched boundary regardless of what mkdir reports — a raced
"already existed" is not "already durable".
- One image walker (imageBlockIn/imageInEvent) now serves both attachment
authorization and the selection gate; referencedImage therefore also
authorizes references inside wrapped message content.
- InputHub: the scope disposer resolves the conversation service optionally
(teardown/HMR must reach quiescence), and a send failing after its scope
died releases the in-flight drafts instead of restoring them onto a
disposed shell.
- http-bridge destroys declared-oversize requests with connection: close
instead of draining a body the client can trickle indefinitely.
- LlmService validates AND detaches modality arrays identically on the
advisory and exact routes; READMEs record the fourth INVALID_MODEL_INFO
rejection reason.
- CLI provider docs (JSDoc, README pair, Agent Note pair) describe the
reuse behavior; llm-route.spec now parses the SHIPPED cordis.yml through
the production extraction, pinning the row coupling.
- image-display lane pins gallery/rail shape in inline snapshots and the
object-URL scheme this environment must take; stale host.schema comment
dropped.
New unary method in RpcMethodMap with the title-invalid error code; the impl
resolves the agent (cold sessions resume first) and delegates to
ctx.sessionTitle.rename, returning the normalized title plus its event seq so
clients settle the title projection cell ahead of the push frame. session.fork
stays on the reserved-seam list.
- resolveLlmRoute: reuse the yml pi-ai row for providers it already routes
(DUPLICATE_ADAPTER boot failure) and detect an unset model by origin, not
by comparison against one deployment default; covered by a new spec.
- LlmService.resolveModelInfoFor preserves (and validates) modality
metadata, arming the host image preflight for exact-route resolution.
- session.selectModel refuses a text-only target once the session log
carries an image on any replayed route; an accepted switch would strand
every later turn with no in-product recovery.
- The composer no longer gates image intake on the handshake activeModel
snapshot (wrong authority for a per-session decision); the host preflight
plus the error strip own capability, deployment limits stay client-side.
- InputHub shell teardown releases the scope's draft images (File objects
and object URLs leaked for the page lifetime).
- session.prompt image parts carry optional alt into the durable block;
ImageBlock documents assistant-side rendering as forward compatibility.
- Assembled built-client lane apps/web/tests/image-display.snapshot.ts pins
the history galleries over the authorized attachment route, the lightbox,
and the composer paste rail; the attachment rail is an accessible group.
- Docs: validateImage on the seam page, fixture byte metadata matches its
PNG, and the Agent Note claims now match the shipped coverage.
