Merge current master and CI readiness repairs into in-history updates
...
Preserve prepared-route admission and V3 prompt semantics while adopting latest master. Regenerate the new model-switch recording at its actual upper-layer title ordering, retain the V2 predecessor, and keep queued-image and publint lifetime assertions strict.

fix(agent-loop): admit prompts under the prepared route
...
Resolve agent/request and prepareCall inside the accepted open step before committing system and user input. Preserve prompt-assembly model selection, bind capability and dispatch to the same prepared adapter, then log the envelope and derive the request synchronously. Preparation cancellation leaves a balanced empty step with no admitted input.
Normalize incapable-route retained prompt versions with logged per-node empty replacements and a current head, including unchanged rendering and resumed history. Dormant empty tails do not override the effective prompt. No new event or delete operation.
Tests: 389 agent-loop cases pass with exact agent.ts/runtime-context.ts coverage at 100% for all metrics; tsc -b packages/core/agent-loop/tsconfig.json passes. Seven actual-loop MockAdapter cases exercise pi-ai conversion, source-event reconstruction, both route transitions, resume, cancellation barriers, and bound selection. Stale-capability negative control fails all three transition regressions. Update EN/ZH request visibility, lifecycle generator, and owning rationale. Broad catalogs, recorded SDK/GUI and aggregate gates remain parent-owned.

refactor(agent, session-controller): drop the unread startedTime frame field
...
The `start` frame and the reconnect baseline attempt carried a wall-clock
`startedTime` that no Host or Client consumer read: the Host accumulator
and the Client reconciler copied it into their attempt maps and nothing
looked at it again. Presentation frames now carry only the coordinates
consumers use (attempt, revision, turn, step, chunk index, and v1 seq
provenance); the type-equivalence block, event graph, READMEs, and the
live-stream Agent Note follow the type.

refactor(session-persistence)!: handle-based seam with a lifecycle-owned write path
...
The persistence seam is now create/open/stat/list returning per-session
SessionHandles (read/append/flush/close); every log read and write flows
through the owning handle. The seam package exports only the service and
handle contracts, consumer-visible errors, and pure durable-data
validation helpers; each backend owns its complete storage runtime, and
the shared contract suites pin equivalent observable behavior. The
backend routes published sessions' live events by id into the active
write handle; agent-loop only acquires, seeds, and closes the handle.
Resume appends interruptedTurnClosers through its write handle;
session-query owns the revision-keyed cold cache. Legacy-only surfaces
are removed in the same swap: locate/readRaw/supportsRawArtifacts, the
legacy event-shape read migration, zstd torn-frame salvage,
DSH_SESSION_JSONL, and hook transcript_path population; a torn final
zstd frame is discarded whole; the session-list cold blank probe returns
on stat metadata (eventCount derived from the last physical row,
sizeBytes). The WebUI ZIP export serializes the logical log from a read
handle, so both backends export identically.

fix(session-projection): close review findings from the fold migration
...
- permission-presets: register the permissions unit synchronously before the
existing-session sweep, so a remount reads folded knob state instead of
treating every session as fresh; add a regression test for that path
- sandbox-policy/terminal-bash: mount the projection registry in the 5 pwsh
terminal tests, the sdk-minimal bundle, and the e2b fixture composition;
declare the new package dependency in both manifests
- plan-mode: restore .strict() on the plan unit state schema and drop the
deleted foldPlanMode from the bilingual READMEs
- session-title/session-projection: sync bilingual READMEs to the mandatory
projection seam and re-record translation pairing
- docs: turnBoundary reader contract, subagent schema comment, token-meter

fix: address ds-review-bot findings on the projection migration
...
- llm-retry: validate config before registering the projection unit;
document the branded-retry-id zod cast; start stateVersion at 1.
- agent-loop: register turnBoundary only after every config validation,
so a rejected constructor leaves no unit behind; the defensive-cap
test no longer needs fiber cleanup.
- agent-instructions: keep newest-first per-scope change history so the
latest visible change survives a surface replacement shadowing the
newest one (restores the previous scan-visible semantics); add a
regression test for the delete-after-shadow sequence.
- tool-skill: keep catalog-message history so a shadowed newest catalog
message still falls back to the latest visible digest.
- session-query-sqlite: drop the unused required sessionProjections
injection.
- plan-mode: restore the command/done error-drop regression test and the
cold-replay command/done fold; drop the inaccurate state-reference
comment.
- tool-todo: remove a stray blank line; document the turnBoundary
reader contract on the projection type.
