Reconciliation of the diverged tool-toggles seam (2026-09-19, master's
P2): Platform injected the resolved delta as an ad-hoc intersection on
AgentBuildOptions while the factories' enabled? param sat unread — the
seam was inert on both sides.
- teacher-agent: AgentBuildOptions gains toolToggles?: EnabledTools;
both constructors thread it to the factories (createTeacherTools /
createProberTools). An explicitly injected opts.tools registry is
never filtered — the caller owns it.
- Vocabulary ADJUDICATED with the user (2026-09-19): TOGGLEABLE_TOOLS is
the definitive list — the job tools only (research/demo/visual/pdf).
quiz/ask_user_question stay always-on forever (the prober's flow is
graded-quiz brackets -> probe_done; quiz-off collapses assessment and
teaching doctrine is built on graded verification — the wedge danger);
the learner-fs set, plan tools, and probe_done also always-on.
- settings-body (write side): unknown tool keys reject with 400 + the
supported list, mirroring the prompt-switch validation; the read-side
sanitizer stays lenient for forward-compat.
- chat-handler: the intersection is gone (field now first-class) and the
seam comment states the adjudicated vocabulary.
Gates: typecheck, 28 new/updated tests green (tool-toggles-bridge,
question-tools, settings-body), chat-flow + settings suites green.
