* feat(workspace): stop a Session's running work before archiving it
Archiving was a pure visibility write, so a Session archived mid-turn kept
running out of sight. The Workspace registry now owns archive admission
through two Host events: `workspace/session-activity` reports what still
runs and refuses the plain archive as `workspace/session-active`;
`workspace/session-stop`, requested with `stopActivity`, stops that work the
way the user's own stop actions do before the archive write. The API Session
Controller reports and stops turns, subagent descendants, and owned jobs and
rejects any model step for an archived Session; the Schedule plugin reports
and deletes active reminders. The sidebar turns the refusal into a
stop-and-archive confirmation listing the Host's answer.
* test(workspace): pin the widened archive signature and prove child liveness by heartbeat
The Client inspect catalog spec pins archiveSession's new options
parameter, and the archive e2e reads the Bash child's liveness from a
heartbeat file instead of a pid: the Linux sandbox runs the tool in its own
PID namespace, so the pid it reports is not comparable from the test.
* test(workspace): cover the archive-admission providers and dialog to the per-file gate
Drop the provider's unused disposer and the dialog's unreachable confirm
guard, read reminders without a catch that no composition can reach, and
add the cases the coverage lane found missing: a stop without a jobs
registry, a looping lineage, a descendant whose projections reject, the
dialog's Escape guard and non-Error reason, and a family merged by another
provider.
* fix(workspace): write the archive before stopping, gate subagent lineage, and delete reminders under the schedule barriers
Review round on #4765. The registry now writes the archive set before it
dispatches `workspace/session-stop`, so the durable set already gates
every wake the stops induce; the controller's `agent/pre-step` gate also
blocks subagent descendants of an archived Session and contains each
cancel or kill on its own. The Schedule plugin's stop listener runs as a
management delete in the agent's transaction queue between the same two
persistence barriers the `schedule_delete` tool uses. The confirm dialog
selects singular or plural English lines and keys list rows by index.
Docs: archive-admission section with type-equiv blocks on the workspace
subsystem page, write-first order and residual windows in the READMEs
and the Agent Note, and the missing zh reminders sentence.
* test(web): scope the question composer's New Session wait to the Sessions tree
The wide sidebar's New Session button carries the same visible label as
a fresh session row, so the unscoped `getByText` either settled on the
button before the row existed or hit a strict-mode violation once the
row rendered first, which is how the snapshots lane failed on
ece68c2ab5. Waiting inside the Sessions tree names the row alone.
* fix(schedule): answer archive admission from the owned runtime's fold, not the projection registry
The `sessionProjections.snapshot` API is the Client projection view and
is not a Host read path (review on #4765). `ScheduleRuntime.activeRecords()`
folds the live log the way every drive does, and the archive-admission
listeners ask the owned runtime for that fold: a session without a live
agent or without an owned runtime has nothing armed to fire, so it reports
nothing and has nothing to stop. Covers the runtime-less agent, a fold that
turns unreadable at the persistence barrier, and the stopping/faulted
runtime answering nothing.
* refactor(subagent): report and stop subagent descendants from the Subagent runtime
The `subagent` family of archive admission moves out of the API Session
Controller into `dsh-subagent`, which records the lineage at delegation
and owns the descriptor (review on #4765): `SubagentRuntime` answers
`workspace/session-activity` with the running descendants, labelled from
each child's descriptor through a live Session observation, and
`workspace/session-stop` by cancelling each of them with the parent
cause. The controller keeps turns, owned jobs, and the lineage step gate,
and composes its provider through `ctx.plugin(SessionActivityProvider)`
with declared injections instead of a bare installer call. `dsh-workspace`
becomes an optional type-only peer of `dsh-subagent`.
* refactor(jobs): answer archive admission for owned jobs from the job registry seam
The `job` family moves out of the API Session Controller into `dsh-jobs`
(review on #4765): the seam's constructor installs the
`workspace/session-activity` and `workspace/session-stop` listeners for
every implementation through the abstract `list` and `kill` alone, so the
controller no longer knows the jobs vocabulary and keeps only the turn
family and the archived-lineage step gate. `dsh-workspace` becomes an
optional type-only peer of `dsh-jobs`.
* refactor(workspace): leave SessionActivityKindMap empty and let each provider merge its family
The workspace package no longer names any activity family (review on
#4765): `SessionActivityKindMap` is empty, and each provider merges its own
key from a module both its faces import — `turn` in the API Session
Controller's types, `job` in the job registry seam's view, `subagent` in
the Subagent runtime's control types, `schedule` in the Schedule plugin's
types. The confirm dialog imports those modules for its cases and keeps
the generic line for any other key; the registry and controller suites
merge test-owned families instead of borrowing the providers'.
* refactor(agent): report and stop the running turn from the Agent registry
The `turn` family moves out of the API Session Controller into `dsh-agent`
(review on #4765): the registry's constructor installs the
`workspace/session-activity` and `workspace/session-stop` listeners for
every Agent it publishes, answering with its own lookup and cancelling the
turn with the user cause, and merges the `turn` key from its client-safe
types. The controller keeps only the archived-lineage step gate, renamed
`ArchivedSessionGate`. `dsh-workspace` becomes an optional type-only peer
of `dsh-agent`; the workspace package depends on none of the providers,
so the edge stays acyclic.
Since #3127 a foreground Bash command is a registered job from its start,
so the archive dialog lists it beside the turn; the e2e and its ARIA golden
expect that row, and the capture keeps the running job by design.
The session-controller README, the per-session store JSDoc, and the projcache predecessor-recovery and durable-web-queue-recovery notes described one higher-seq-wins rule and the asOfSeq -1 title hint. They now state that higher-seq-wins applies among Host-sequenced values, that cached list blocks yield to the connected Session's baseline, and that the predecessor title carries its stored row's watermark under kind: 'cached'.
Attachment reads and ZIP export previously inferred ownership from common
field names on arbitrary events. Opaque ignorable plugin payloads could
therefore cause storage reads, while declared compaction content was missed.
Select attachment-bearing fields by current built-in event type in both
readers. Read direct image and file blocks, including flat V4 tool results
and developer messages, without interpreting extra block fields. Leave
unknown payloads and malformed inbox entries opaque. The archive preserves
the complete logical log even when its payload does not authorize a read.
V4 validates title requests as one text block, so do not treat them as an
attachment carrier. Compaction keeps its declared ContentBlock fields for
valid custom producers; the basic producer's text-only output is documented.
Historical wrappers remain the adjacent converters' responsibility rather
than a second compatibility path in attachment readers.
Adapt the original policy change to master after V4 landed, retaining its
author credit and scope. Cover tool-result export explicitly, keep Team
fixtures free of invented message roles, and verify that denied carriers
never read storage. The 889 owning tests pass with 100% statement, branch,
function, and line coverage for both changed runtime 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.

Merge master 01d96c168a84227374e3aa741e94ddfbb498e27e, observed when
this integration started, after the published 6de3db41 checkpoint. Keep
master's author history and preserve the release writer, adjacent
migrations, historical Session generations, and parent-owned catalogs.
Combine blank Session writer acquisition and superseded-startup
cancellation with the release branch's projection refresh and panel
preservation. A startup acquisition may finish after a later navigation,
but must not retain a stale main Session or reveal its Conversation.
Update the existing regression's retention expectation while preserving
its panel and active-navigation assertions.
Keep the release catalog loading, known-leaf, and parent availability
behavior alongside master's completed-turn status and aligned sidebar
icons. Regenerate the config locations and pair the combined README
contracts. Preserve upstream's Linux process-state assertion repair.
* fix(session): keep blank session discovery local to each host
* fix(session): acquire blank writers before reusing sessions
* refactor(workspace): separate saved selection restoration from blank lookup
* fix(workspace): create after the selected blank writer is held
* test(web): align blank reload snapshot with current icons
Merge a2acc7d3eb620bb52f09f7ea3b5a3a1c23353e18 after preserving the earlier
master checkpoint and its successful CI. Carry current provider input-history
handling, UI controls, agent targeting, and runner-concurrency changes into
the integration base without changing the Session migration feature layers.
Keep durable direct-child catalog semantics alongside the upstream running /
inactive vocabulary. Resolve the snapshot description conflicts by retaining
that upstream status text and the existing descendants-only diagnostic rule;
the source and all 53 JSON tool descriptions agree. Preserve parent-session
availability handling with the upstream stale-blank and batched-history fixes.
The merged application builds, all 41 documentation gates pass, and focused
provider, tool-control, and Session Controller tests pass (98, 29, and 125).
Recorded input changes come from master: one refreshed v3 list-agents sample
and three new v3 scenarios; no migration bumps an existing snapshot generation.
