Whether concurrent active tasks are legitimate depends on runtime
concurrency the tool cannot observe, but whether a deployment's agents
ever fan out is knowable at composition time. `allowParallelInProgress`
(default true) therefore replaces the hardcoded policy: the flag moves
the model-facing instruction and the accepted input together, so a
deployment running strictly sequential agents can restore the
single-active discipline from cordis.yml.
The durable-log invariant does not follow the flag. A log written while
parallel work was allowed must still replay after a deployment tightens
the policy, so the invariant stays silent on the active count.
The fixture committed the generated Linux workspace path instead of the
`{{cwd}}` token every other acp recording uses. The normalizer masked it
so replay passed, but the next record or refresh would rewrite the file
for no reason; refresh is now byte-stable on it.
The Agent Note's schema-pin arithmetic predated master's
`toolSchemasSource` sharing: seven of the eight sidecars carry the todo
schema, and scenarios composing an identical header share one rather
than each keeping a copy.
The web-fetch pinsHeader scenario landed on master after this branch, so its
tool-schemas.expected.json carried the old at-most-one-in_progress description
while replay assembles the new one. Refreshed keylessly with
DSH_SNAPSHOT=refresh; the Agent Note now records that every pinning scenario
carries its own copy of the description, so a branch changing it has to refresh
the pins that landed after it branched.
Both todo one-line surfaces truncate the active hint with overflow: hidden
and text-overflow: ellipsis. A "+N" appended to the first active task's name
therefore sat at the far end of the truncatable text, so a long task name or a
narrow viewport clipped exactly the part that reports the other running tasks,
leaving a parallel plan indistinguishable from a sequential one.
planSummary now returns activeContent and activeExtra as separate fields
instead of one joined activeHint, and each surface renders the count in its own
flex: none span beside the ellipsized name: .activeExtra in the collapsed plan
strip header, .extra in the todo_write row. Putting the count in front of the
name was rejected — the task name is what the reader looks for first.
The parallel-plan cases in todo-panel.spec.tsx now assert the count is a
separate element from the name, and both fail if the two are rejoined. The
assembled web snapshot re-records: the flex gap supplies the visual space, so
the transcript reads "实现 fixture 样本+1" with no space in the text nodes.
Lifting the single-in_progress cap makes a list shape reachable that the
web surfaces never received. Two sites derived their one-line summary with
todos.find(t => t.status === 'in_progress') — the collapsed TodoPanel header
and the todo_write row — which was total under the old cap and silently
dropped every active item but the first once several could match: a plan
with three running tasks collapsed to the name of one. The expanded list
was always correct, so neither PR's tests covered it.
Both sites now take planSummary in contract/todo-plan-model.ts, the
domain-shared face both the skeleton and toolviews domains may import; the
duplicated derivation was why one find could be fixed while the other
stayed wrong. The hint names the first active item and suffixes +<n> for
the rest, so the collapsed line reports how many tasks are running.
The web fixture's todo sample now runs two items in_progress, so the
assembled web transcript replays a parallel plan: the row reads
'1/4 已完成 · 实现 fixture 样本 +1' over the built bundles.
Remove the single-in_progress cap from todo_write execute validation and
the durable-log invariant so a task list can mirror genuinely parallel
work (concurrent subagents, background commands). Update the tool
description to instruct marking every actively worked task in_progress,
refresh the tool catalog and keyless snapshot expected outputs, and
record the decision in a new Agent Note superseding the original cap.
