Integrate the observed master checkpoint 7ab215e23e5d977aae7eb5d4fb91782d39969dbb without rewriting the earlier published checkpoints. Master adds current-directory events, directory-aware consumers, and retained Git worktrees; its old subagent startup paths overlapped the unified activation implementation.
Resolve directory selection within managed startup after acquiring parent ownership. Preserve the original Session origin while setting each new local child directory, retain persisted directory state on cold resume, and pass a required absolute cwd to external providers. Keep unified local/external ownership, full completion notices, parked-input host completion, SDK wait/error/shutdown behavior, and ACP cancellation semantics. Retain removal of the old in-process driver and continuation managers.
Combine SDK wait with the new directory requests, preserve the new master directory/worktree fixtures, regenerate derived catalogs from the combined sources, and refresh only the four stale prompt/schema sidecars. Preserve every protected historical schema, archived note, catalog-v2 acknowledgement, and recorded predecessor input.
Validation: full build; 59 CI static gates; 855 subagent tests with 100% coverage on changed core/external sources; affected consumer suites including 119 repaired-fixture tests; SDK 11 and headless 16 recorded scenarios; two local headless expected cases; six built nested SDK/ACP cases; lint, strict cast inventory, workspace constraints, and whitespace checks. Native Windows worker diagnostics remain additive and require the next CI run to classify the original crash.
Integrate master 78ae4fc2d4d8ecaebb4b674028f781a358b92cc9 after the four
independent review fixes. Keep this base update separate from those fixes
and from subsequent review changes so the integration is independently
reviewable and the observed-master checkpoint remains preserved.
Retain activation-owned execution, caller-independent local discovery,
and unconditional parent final-answer delivery. Preserve master's preset
scoped scheduling tools and all delegated-child schedule deny rules. Move
the new scheduling regression from the removed driver package into the
surviving subagent package and run it through a real Spawn activation.
Preserve master's removal of runtime invariant plugins, dependencies,
exports, and test mounts. Keep context disposal before fixture directory
cleanup. Combine Python workflow ordering with activation/catalog events
without inventing unsupported source-plane import paths.
Keep all frozen Agent Note archives byte-for-byte identical to master;
do not accept Git's automatic edits to renamed archived notes. Retain
current lifecycle and delivery facts in active documentation, repair its
links, and regenerate catalogs/persistence schemas from merged source.
All 62 master persistence roots remain; only subagent/catalog gains the
PR's external membership extension. Keep master's third-party lock graph
and update only workspace dependency changes.
Validation before this checkpoint: 683 focused tests passed, seven
Windows-only cases skipped; 2,772 archived artifacts verified. Generated
catalog and active-pair checks passed. Fresh artifact build and remaining
build-dependent documentation checks continue before publication.
The installed-wheel smoke checks real model tool use and externally verifies
the created file, a fresh host-only challenge, the copied receipt, and the
unchanged source. DeepSeek can return the requested acknowledgement before
a file-details paragraph; requiring it to be the last line makes correct
SDK execution fail according to the placement of explanatory prose.
Accept the exact acknowledgement on any standalone line, retaining completed
turns, model-requested tool calls, exact file bytes, and session-log checks.
Replay the observed response through both turns and keep negative coverage
for absent or embedded acknowledgements and incorrect files.
Session V4 reserves developer-role messages for incremental model-visible
session changes. The role, tool addition/removal blocks, and deferred-loading
marker need a durable representation before independent provider and UI
integrations can emit or consume them. Known developer events must match an
open turn and step; unsupported providers and UI consumers fail explicitly.
Request headers already capture full tool definitions. Persisting another
ToolSchema in each addition would duplicate Session information and create
two definitions that could drift. Additions therefore store toolName, and
the containing developer event uses headerSeq to select one earlier known
request/header for all its additions. A same-name replacement keeps its
historical definition identity through restart, fork and surface changes.
Removals require no definition copy, and ordinary developer messages omit
headerSeq. Generic sourceEventSeqs remains independent derivation metadata.
The rejected inline tool field is optional never with @persistenceReserved.
The schema extractor retains that uninhabited slot, so permitting a future
value requires a format bump instead of being mistaken for compatible
optional metadata. Unrelated optional fields remain additive and readable.
Native and Session admission reject missing, forward, non-header, unknown,
ambiguous and incomplete referenced definitions, and reject the retired
inline tool field. Validate complete schema fields only for referenced
definitions, preserving unrelated header behavior and extra JSON metadata.
Unknown ignorable records remain opaque. Empty developer nodes retain their
surface position without producing a message or shadowing the system head.
No automatic emitter, provider activation, UI implementation, or speculative
public resolver is added.
Keep the core-owned developer source binding beside the introduced role,
including the request-only type rejection and attribution round trips. Update
consumer guards, SDK/snapshot handling, bilingual owner documentation, and
the same unreleased V4 acknowledgement. Keep earlier tool/source migration
work and its documentation in the parent. Preserve the existing recorded
Cordis inspection generation from the original developer change.
Integration keeps the final source layer as the sole parent and preserves
master's Messages input filtering, empty-user omission, empty tool results,
and system-update placement. Developer/deferred guards still run before
conversion. Native V4 admission, header references, reservation declarations,
and generic tooling match the validated marker candidate. Parent-owned
fixture and generator fixes remain in the parent.
Earlier feature validation passed full build, full lint, 41 doc-sync gates,
and 16 hygiene gates. The unchanged native implementation retains that evidence.
The focused Session/V4/request-input run passes 884 tests across 38 files with
100% statement, branch, function and line coverage for the V3-to-V4 package
and Session surface. Consumer tests pass 482 with one existing skip; tool,
message and optional-field tests pass 146. Cordis inspection and compaction
replays pass in both source and built modes (two cases per mode). Ten invalid
referenced-definition/unknown-header controls failed before their scoped
guards and pass after them.
Reservation validation: the actual generated developer root records tool as
optional primitive never. Widening it requires a bump, while traceId remains
additive and preserved; all 85 focused reader/classifier tests pass.
Final-parent validation: 205 tests across eight provider, type, catalog,
Session and native-format files pass. The preserved parent fixture verifies
Messages input-history replay; runtime/declaration and parent-owned-file
comparisons show no loss during the final rebase.

Represent tool results as tool-role messages and migrate released wrappers
without losing outer own JSON fields, call identity, error state, or writer
field order. Refuse nested or wrapper-only information that has no lossless
current representation before successor publication.
Validate current event relationships directly instead of projecting V4 data
back into V3. Keep lifecycle, PTC, title/command, compaction, system-field and
retired-syntax checks on catalog restoration and ordinary JSONL opens. The
Worker JSON equality helper must inspect own keys so it cannot admit PTC
arguments that Node rejects.
Keep the source role change, required native admission and consumer fixture
updates in one complete review layer. Explain shared-type changes in the
persistence record and the native reader rationale in its existing note.
Use checked branded fixture identities and discriminant narrowing instead
of unknown double casts; fixture values and assertions remain intact.
This recomposes the original tool-role work by _Kerman with the independently
validated migration and admission repairs by Tianyi Cui. Frozen generations
and snapshot input version selection are retained.
