An image with a side above the deployed routes' 2000px many-image bound
could be durably committed by read_image, ride every later request, and
permanently fail the session with provider 400s. Admission now enforces a
configurable maxImageDimension (default 2000) during the full decode, so
read_image surfaces a recoverable tool error naming the limit instead of
poisoning durable history; the Web composer gets dedicated copy for the
new IMAGE_DIMENSION_TOO_LARGE reason.
Fixes#2626
A max-tokens response that included a tool call persisted assembler-transformed
content next to replay metadata projected from the untransformed native message,
so the next request died in history reconstruction with INVALID_REPLAY_STATE and
the session stayed permanently stuck.
Write side: the finish chunk's replayState becomes a typed ReplayEnvelope —
opaque response-level metadata plus optional per-block entries aligned with the
emitted block sequence. BlockAssembler computes one keep/drop decision for
blocks and entries together, so stored metadata always describes stored content
and retained blocks keep their signatures. pi-ai splits its state into a
version-2 response half and per-block signature entries.
Read side: durable content is authoritative. toPiAssistant degrades any
unusable state — foreign kind, other versions (including the flat v1 form
already on disk), malformed metadata, or content/block mismatches — to the
existing provider-neutral conversion with an onReplayDegrade diagnostic instead
of failing the request, which un-bricks sessions poisoned before this change.
Covered by assembler and replay unit tests, an agent-loop continuation
regression, keyless real-composition continuation tests (native pruned-envelope
replay and legacy flat-state degrade), and the authored keyless snapshot
scenario max-tokens-continue through the assembled ACP app.
The shipped bundles keep ctx.sessionQuery mounted but set the new
session-query-sqlite `openAt: never` phase: searchSessions/searchEvents
fail with the typed SESSION_QUERY_SEARCH_DISABLED code before any request
normalization, node:sqlite is never imported or opened, and no source
observation or reconciliation runs. Every inherited exact read, filter,
and trace — session export descendants, subagent-fork Workspace
inheritance, title reads — keeps working, and the Web sidebar search
degrades to its designed local title/workspace matching. Enabling content
search is a one-line openAt override in a later patch layer; the web e2e
scaffold keeps it enabled as the assembled opt-in coverage.
turn/start precedes the first claim and pre-step, a rejected or empty first claim closes a zero-step turn, llm/stream and tools/* are their own domains, and agent/turn-stopping is serial. Regenerates the lifecycle diagram from the same facts and names --patch overlays exactly.
Correct the reworked English wording in the CLI profile section, architecture map, and llm-streaming cross-reference, then bring every edited pair's Chinese side along and re-record the pairing hashes.
Keep both Remote contributions master and this branch add: the mount loop
now carries commandsRemote, goalsRemote, pluginInventoryRemote, and
messageFeedbackRemote, with both new tsconfig references retained.
Overlaps master on the preset e2e, the web scaffold, and the generated
config-catalog triplet; all merged textually, so the catalog is regenerated and
its pairing hashes re-recorded rather than trusted.
Adapt to two contract changes master introduced:
- The generated Remote face now wraps every business result in
RemoteResult, folding carrier failures into an ok:false branch instead
of rejecting. The controller reads that envelope at its three call
sites and maps a carrier failure onto the same settled shape the
controls already render; three specs cover the new branch.
- Client packages split their tsconfig into host and client halves, and
the host aggregate now compiles any test not named *.client.spec.*.
Rename this package's specs to the client convention and drop the
../connection project reference, which pointed at a solution file that
no longer carries the client sources.
Keep master's mount loop with its rollback-on-failure in api-remotes and
add messageFeedbackRemote to it.
