Add @deepseek-ai/dsh-agent-model. It provides ctx.agentModel
(resolveForNextStep, select, applyConfiguredRoute) and owns the
modelSelection projection, which the Agent registry no longer registers.
dsh-agent-loop now injects agentModel; the base and SDK-minimal bundles
and the Python SDK runtime include it.
The provider keeps the projection registered until consumers that are
still unloading finish their cleanup. The model-switch notice becomes an
opt-in per-Agent plugin at @deepseek-ai/dsh-agent-model/notice, and
agent/request now also rejects reasoning-effort changes after step
preparation.
Mount the provider in every composition that loads dsh-agent-loop, and
update consumers, the switch-notice snapshot driver, docs, and the
upgrade guide.
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.
Interrupting a local child can preserve unclaimed steering while leaving the Agent idle. Activation residency intentionally continues in that state, but completion barriers joined its result forever. The real SDK server reproduced the hang for both direct children and a nested parked leaf.
Join progressing work and cleanup while retaining parked inboxes and their activation results. Observe local activity and maintenance, external execution, unpublished ownership holds, and materialization; rescan after changes. Recheck resumed Agents after concurrent idle observations. Inbox insertion and ownership publication wake pending observations, so late non-waking injection cannot strand a result wait. Existing descendants remain responsible for their own work; no second state store or polling timer is introduced.
Document that persistent SDK/ACP hosts keep these children available for later wake-up, while headless shutdown discards unclaimed input. Simplify the final settlement recheck to retry changed readiness uniformly. Update generated API and event references from their sources.
Validation: real SDK negative controls fail at both depths on the prior manager with clean teardown; 545 tests pass across 27 files. Manager, local activation, and headless runner each reach 100% statements/branches/functions/lines. Six deterministic races cover revival, preparation publication/rollback, flush-time injection, and late children. doc-sync 42/42, targeted build, lint, and whitespace checks pass.
A child completion can wake the parent after its first completed turn. If
that summary cannot append turn/start or turn/end, AgentLoop reports an
agent/error and contains the rejected driver. Whole-agent idleness then
resolves, but the headless runner previously reused the older completed
terminal and exited successfully, sometimes printing the older answer.
Retain failures from the exact owned Agent with the current Session log
offset. Only a later terminal committed by the same Session clears that
failure. After work and persistence drain, fail the run before emitting a
final answer when no such terminal exists. Dispose both observers with
the run. Ordinary durable error outcomes and later successful recovery
continue to use the log's final terminal.
Add real AgentLoop regressions for missing summary start/end commits in
plain and JSON output, ordinary hook failures with and without recovery,
recovery after persistence failures, and unrelated Agent errors. Update
the bilingual exit contract and generated event consumer matrix.
Validation: 106 headless package tests; 100% runner statements, branches,
functions, and lines; 9 focused terminal-failure tests after the typed
append wrapper correction; package TypeScript build; full lint including
host build; 21 quick documentation checks; 42 doc-sync checks; diff check.
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.
Delete @deepseek-ai/dsh-invariants, every package's ./invariant companion
and its tests, the invariant gates and Vitest setup, the scoped-event
resolver generator, and the INVARIANT-coded listener rethrow paths.
Update docs, READMEs, Agent Notes, and add an upgrade guide.
