* fix(subagents): wake the parent when a follow-up finishes a yielded child
A sub-agent that calls sessions_yield on its own behalf parks its run and
correctly withholds the parent's announce. But a later follow-up to that same
child session registered a sibling registry row instead of continuing the paused
one, so the requester defaulted to the child's own main session and the original
parent — itself idle behind sessions_yield — was never woken. The paused row also
stayed an unsettled descendant, deferring the parent's settle batch forever with
nothing recorded explaining the silence.
Follow-up dispatch now adopts the paused row through the existing post-steer
replacement seam, inheriting the requester identity and carrying the settle-wake
credential forward with its frozen batch membership remapped to the new run id.
A follow-up that names its own requester keeps registering separately, since an
explicit requester is a delivery opt-in that adoption would silently drop.
Also stops frozen-result refill from targeting paused rows: a yield clears the
result on purpose, so refilling from the session would attribute a later turn's
text to the paused run.
Closes#120157
* fix(subagents): select the paused owner past a requester-bound sibling
Adoption looked up the newest run for the child session and adopted it only
when that row was itself paused. A requester-bound follow-up deliberately stays
a sibling, but it registers at a higher generation and becomes that newest row,
so any later default follow-up saw an unpaused newest row, declined adoption,
and registered yet another sibling. The original requester stayed parked behind
a paused row that can never announce -- the same silent stall this fix exists to
remove, reached through a valid mixed-delivery sequence.
The latest-run query now takes an optional predicate applied before the
generation comparison, so a caller that owns a specific row class selects the
newest row of that class. Adoption asks for the newest `sessions_yield` row
directly instead of inferring it from generation order.
Docs now state that continuation applies to default delivery, since a follow-up
carrying its own requester runs as a sibling by design.
* test(qa): prove post-yield follow-up delivery through the gateway boundary
The unit and gateway-method tests for paused-run adoption assert on registry
rows, which proves the bookkeeping but not that an operator ever sees the
result. This adds the boundary proof: a real gateway child, the QA mock channel,
and the mock provider driving a subagent that pauses itself and finishes only on
a later follow-up.
A fixture plugin owns both legs. Its `before_dispatch` hook spawns the child with
`completionDelivery: "current-requester"`, so the announce has the operator turn
as its audience. An HTTP route then dispatches the follow-up to that same paused
session using default delivery -- the path adoption is meant to catch. A
requester-bound follow-up would opt into its own audience and run as a sibling
instead, so the two legs must differ here.
The mock provider gains a child that yields on its own behalf. Both of its turns
match on the current prompt rather than the shared transcript, so the yielded
kickoff cannot make the follow-up turn yield a second time.
The scenario asserts both sides of the invariant: no outbound traffic while the
child is paused, and exactly one announce carrying the follow-up marker once it
ends.
Reverting the adoption call site fails this test in the way that matters: the
child still produces its marker and the run still ends with stopReason=stop, but
nothing reaches the requester and the wait times out. The result is computed and
then silently dropped -- which is the failure this repair exists to remove.
* fix(ci): match QA Lab fixture plugin entries as a group in knip
The all-exports pass listed one fixture entry by name, so every new QA Lab
fixture plugin lands as an unused file and turns check-dependencies red until
someone remembers this file. Nothing imports these entries by design: the
Gateway E2E loads them through plugin config paths.
* docs(subagents): scope yield continuation to plugin runtime follow-ups
Adoption is gated on plugin_subagent task tracking, which only
createGatewaySubagentRuntime().run sets, so api.runtime.subagent.run is the
sole route into it. Writing that as one example implied other follow-up paths
to a paused session continue the run too; they are not tracked as sub-agent
runs and announce nobody.
* fix(subagents): reject undurable paused-run adoption
Fail plugin follow-up admission closed when the paused-run ownership swap cannot be persisted, while retaining the existing restart-recovery return-false contract. Trim duplicate tests and keep boundary coverage for requester routing, wake-batch remapping, repeated yield, and persistence rollback.
