Master removed `backgroundMode` and the `run_in_background` argument, so
every delegation starts a managed activation. Mount the working-directory
owner SubagentRuntime injects and the JSONL persistence root the spawn
provider requires, and synchronize on the child's cancellation, which the
parent teardown or the manager drain raises instead of a parent-only cause.
Review caught two real gaps in the previous commit.
The rename dialog's no-op check compared the localized display title, so
on an automatically titled Workspace the seeded prefill equalled it and
Rename stayed disabled — the user had no direct way to pin the visible
name. The dialog now seeds the draft with the label on screen while the
stored title decides whether confirming saves, and the duplicate check
excludes the target by Workspace identity instead of by title, since the
seeded label equals the row's own displayed title.
The registry took the automatic title from the canonical path, so a
symlink at the first-use path titled the Workspace after its target and
the default lost its localized label. The title now comes from the
requested directory's final segment; the path stays canonical.
Also: drop a rotting file count and the stale localized-path wording from
the Agent Notes, record the two cwd-derived Session label fallbacks as
known consequences, trim the WorkspaceBrowser memo comment to the
non-obvious part, and remove the deleted request type from the
hand-maintained catalog LINK_MAP.
The first-use directory name and its stored title came from the Client's
startup language, so one product decision carried two incompatible
requirements: a path addressed by shell commands, tool arguments, @path
references, and session logs, and a label a reader reads.
The controller now owns the fixed `default-workspace` directory name and
the registry titles the Workspace after that same segment, so
`workspace.initializeDefault` takes no request at all —
WorkspaceInitializeDefaultRequest and its name validation are gone, and
the registry resolver returns a path instead of a path and title. No
language reaches the Host.
Browser consumers label a Workspace through the new
`workspaceDisplayTitle`: a title still equal to the automatic one reads
as the localized default name from the `common` namespace, every other
title reads verbatim. The Workspace browser resolves it once at the store
read, so rows, hover card, search meta, and the rename and delete dialogs
inherit it; the hero picker and the Conversation chip resolve it too.
Confirming a rename stores the text on screen, which is what stops a row
following the language.
* fix(session): repair interrupted turns during V3 migration
* docs(session-format-v3-to-v4): state reference remapping in the summary and code
The frontmatter summary still promised preserved references after the edge
began remapping audited same-artifact references around an inserted
interrupted turn/end. Two local comments record why the opaque branch moves
only `seq` and why the open-step flag needs no reset at a turn boundary.
* docs(session-format-catalog): describe the V3-to-V4 edge as a converting link
The catalog listed the edge as an identity conversion, which stopped being
true once it inserted an evidenced interrupted turn/end and remapped the
audited local references that follow.
The 2026-07-16 explicit-turn-cancellation note still described a frozen,
detached signal reason and a two-variant cause union. The README paragraph
added here points readers at that note as the owner of the signal
lifecycle, so the stale mechanism was load-bearing.
It now records why freezing the caller's cause is not an alternative:
undici assigns `stack` from strict-mode code, so a frozen reason makes
fetch reject with `TypeError: Cannot add property stack` in place of the
abort reason.
Also names `turn/end`'s declared `TurnEndCancelCause` in the README and
takes the reviewer's helper-doc wording.
Node's fetch assigns an enumerable `stack` string onto the abort reason
object it receives, and the loop logged that same object into `turn/end`.
The undici trace became durable session data under a field no reader
declares. A transport adding a property JSON discards instead made
`Session.append` reject the ending, leaving a turn with no close.
`abortedCancelCause()` narrows the untyped `AbortSignal.reason` once and
copies the declared fields, replacing the three `as AgentCancelCause`
assertions at the two read sites and the log write.
Re-record the session-snapshot README bilingual pairing sidecar, and admit
the source-reference regression fixture with the v4 producer-owned `user`
message source kind.
Give durable user context its producer-owned source kind instead of a generic plugin wrapper. The V3-to-V4 conversion preserves the frozen rename and collision rules, all own JSON metadata, event coordinates, and historical request-only kinds. Native catalog and JSONL admission retain source validation so unknown attribution can survive without its producer while malformed owned sources are refused.
Use an explicit user-only RequestUserInput for auxiliary LLM prompts that do not own durable message identity. Auto Review and compaction remove their request-only source registrations while retaining prompt content and freezing; provider serializers and projections keep the same wire data, assistant replay isolation, image ordering, and tool correlation. Session writes, Agent delivery, and recorded title requests continue to require identified durable messages.
Bind the saved compatibility policy only to user sources and qualify tmux location attribution without weakening fixed system, model, or tool semantics. Rebuild the current inventory and unpublished V4 acknowledgement on the actual tool-role parent, preserving its rationale and all accepted historical records. The catalog format version records tooling metadata; Session remains V4. Developer-role policy and activation belong to their own feature.
The latest-master Messages adapter, serialization, request-input typing, EpochHeader reservation, and attribution checks pass 103 tests across five files. The retained V3 Messages input-history snapshot passes through the source profile; Host/Client typechecks and all 41 documentation gates pass. The generated comparison records four changed roots and 447 unchanged type fingerprints. Latest-master ARIA changes are retained, with producer source labels applied independently; new Messages fixtures retain their producer names as declared source kinds and use the fixed system-message helper; recorded Session generations are unchanged by this regrouping.

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.

The trajectory ledger now summarizes a recorded run_code call with the
program description instead of its raw JSON arguments, and marks it with
the code-inspection icon. Refresh the Auto-review denial golden so the
replayed ARIA expectation matches the shipped rendering.
Resolve the markdown-preview revert and README proofreading against this
PR's trajectory inspection work:
- CodeBlock keeps `showHeader` (the PTC code inspector supplies its own
toolbar) on top of master's `contentRef` scrollport wrapper.
- ui-primitives README records both `contentRef` and `showHeader`.
- ui-trajectory README keeps master's proofread wording alongside this
PR's PTC inspection and timing paragraphs.
- Re-record the README.i18n.yaml pairing hashes for the three merged pairs.
