SessionTitleInvalidError narrows the one rename failure that blames the
input; the fallback-unpin append extracts to appendFallback beside
ensureFallback's guarded twin; a deferred-provider test proves rename
supersedes ACTIVE generation; the invariant companion enforces
messageSeqs-empty iff user-source on every appended session/title event
(tsconfig gains the session-title invariant path); SessionTitleEventData
field docs state the third source kind and the empty-seqs rule, mirrored
into the bilingual core-data-structures page; the note qualifies the
refresh unpin as conditional on a derivable replacement.
sessionTitle.rename appends a user-source session/title event; onUserMessage
skips scheduling while a user title stands, and an explicit refresh is the
deliberate unpin (provider regeneration, or a re-derived fallback when no
provider is registered).
- 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.
Inherited sandbox and approval events were part of the constructor seed. Session.firstLiveSeq classifies every constructor event as replayed history, so telemetry adoption skipped these child-only creation facts even though no parent or prior process had exported them.
Capture the parent overrides at the same synchronous delegation boundary, but append the events during the child factory setup while the session is still unpublished. They remain ordered after fork history, persist with the first child batch, and retain last-event-wins behavior while landing on the live side of the telemetry boundary. This uses the existing setup and session append contracts instead of adding another seed category or telemetry special case.
Add regression coverage for exporting an unpublished suffix without re-exporting constructor history, assert the spawn and fork firstLiveSeq boundaries, and restore the public seed documentation to replay/fork history only.
The simplified inheritance path uses Session creation seeds for policy events, and the public CreateSessionOptions JSDoc now names that supported role. The type-equivalent persistence catalog still described seeds as replay/fork-only, so doc-sync correctly rejected the mismatch.
Align the explanatory paragraph and exact type-equivalent block in both languages, then re-record the bilingual pair. This keeps the public catalog from understating the constructor seam that makes the simplification possible.
The parent implementation introduced sandboxMode and approvalPolicy as generic SessionHeader fields, then propagated those fields through both persistence backends, session-query indexes, collision checks, policy-specific seed-boundary folds, catalogs, and a broad test matrix. That storage plane is unnecessary: Session already accepts a validated constructor seed, and persistence captures that seed when the session is announced before committing its first batch.
Capture each parent override synchronously at delegation, append source-tagged sandbox/mode and approval/policy records after the optional fork prefix, and create the child with that combined seed. Keeping header.seedLength at the original fork-prefix length preserves lineage while ordinary last-event-wins folds make the inherited records outrank stale parent history and remain subordinate to later child switches. Unswitched parents still stamp nothing, so children continue to follow deployment defaults.
Remove the generic header fields and every persistence/query/schema branch built around them. Collapse the inheritance suite from ten leaking scenarios to four owned-context cases covering real filesystem confinement, stale fork precedence, delegation-time capture, and the no-override path. The assembled headless snapshot now asserts the persisted inheritance event directly.
This keeps the security behavior while restoring policy ownership to the existing event log and deleting the speculative durability machinery that the original tests did not exercise.
Retarget the feature branch to the current master tip without rewriting its existing review history. Keeping this as a dedicated merge checkpoint makes the later simplification diff attributable to the stacked child rather than mixing base movement with design changes.
Resolve the identified-message API drift in the feature tests by constructing complete user messages, reading the nested tool-result message shape, and adapting the prompt-submit listener signature. Preserve both sides of the user-approval conflict: master’s createUserMessage wrapper and the feature’s inherited-policy attribution.
Regenerate the Cordis and persistence catalogs, re-record the session README pair, and refresh the affected ACP/headless fixtures so derived artifacts describe the merged source rather than either parent in isolation.
Validated with the focused policy/session/persistence/query suites (430 tests), focused ACP/headless snapshots (3 tests), build, doc-sync (25 gates), lint, hygiene, and git diff checks.
