The section is a strict subset of the plugin config: `agents` is consumed
once when the service starts, so a stored change there could only look like
it had an effect. The cap resolves through a getter over the settings source,
which the scheduler destructures at the start of each tool group, so a
committed change bounds the next group without disturbing the one in flight.
`resolveMaxParallelToolCalls` becomes the section validator, refusing a value
at the write instead of at that group.
The deferred-resume effect-shape assertion now allows the one plugin effect
the optional settings wiring adds at the fiber's own level; a resumed agent
joining it there is still the regression it pins.
Presets own the rows that decide what a session's `/` menu contains, but
both browser catalogs cache per session and had no invalidation edge for a
recompose: `commands/changed` is registry-wide and recomposing registers
nothing, so the menu kept serving the composition the session no longer ran.
The host stream now frames the logged `agent-preset/selected` commit as
`host/session-preset-changed`; the runtime bridges it to the typed
`session/preset-changed` event, `ui-command` soft-refreshes that session's
directory key and `ui-skill` invalidates its catalog entry.
Reaching the host on a second switch was a separate defect: the list-row
identity guard compared every summary field except `agentPreset`, and the
merge keeps the row's `updatedAt`, so a switched row looked unchanged and
served its cached instance forever. The hero chip compares the pick against
that row, so switching back to the creation-time preset sent no RPC at all.
The skills subsystem page and dsh-skill README describe the host+per-scope
layers, SkillViewOptions joins the type-equiv corpus and the cordis-catalog
type pages, generated catalogs pick up the shifted source refs, and the
architecture Agent Note records the decision, the nearest-layer-wins
precedence choice, and the rejected alternatives.
Master's bilingual-generated-docs policy pairs the five generated catalogs;
mirror the purge's regenerated English (ConPTY note, hooks TODO wording,
thinking-format and SurfaceOp JSDoc, doc-graphs templates) into their
reviewed zh sides and re-record. Condense the evidence-citation clause and
raise the docs/AGENTS.md ceiling 1320→1335: master's seam-trio definition
and this PR's review-mandated evidence rule land in the same window.
