* refactor(orchestration): give structured sessions an orchestration actor column Adds nullable session:<id> actor columns to runs (coordinator) and dispatch_contexts (assignee, creator) at schema v42, a shared codec, a fill for rows that provably belong to a structured worker, and a coordinator mail-address cache that remembers a handle-less coordinator by its actor address. * test(orchestration): pin the actor columns, their fill, cache and v40/v41 upgrade paths * refactor(orchestration): fill structured-worker actors from one open-time call site * fix(orchestration): refuse terminal handles as session actors and clear the assignee actor on reassignment * test(orchestration): read the current schema version from its constant in the delivery downgrade contract The contract asserted user_version 41 after old code reopens a database current code wrote, so the v42 bump failed it. Assert SCHEMA_VERSION so the next bump cannot strand it; the pre-v41 pin and its v40 stamp stay. * fix(orchestration): count a Run's coordinator actor only at the generation it was written at A binary without the actor column rebinds and unbinds a Run by rewriting its handle and pane, which it cannot clear the actor beside. A rebind followed by an unbind leaves a row identical to a live chat binding. Both writes bump consumer_generation, which every binary already maintains, so the actor now carries the generation it was written at (coordinator_actor_generation, set in the same statement) and counts only while the two are equal. The coordinator cache, its triggers and the open-time fill read the actor through one rule in run-coordinator-actor; the fill also replaces an actor an older generation left behind. Still schema v42 (unreleased): the column joins migrate-v42 and the v42 skew-probe entries, so a database stamped v42 without it replays the chain. * refactor(orchestration): drop the unused coordinator-actor index and bare-id normalizer Nothing in this stack looks a Run up by coordinator_actor: callers load the Run and compare its current actor, so idx_runs_coordinator_actor would ship in every database with no reader. v42 is unreleased, so it leaves the migration rather than needing a later drop. normalizeOrchestrationActor had no caller outside its tests; bare session ids enter through sessionOrchestrationActor, and the handle-refusal cases stay covered there and in parseOrchestrationActor. * fix(orchestration): keep the coordinator-actor index the caller lookup needs The next step finds a caller's Runs with one statement that ORs a pane-leaf match with `coordinator_actor = ?`. SQLite splits that OR across two indexes only when both sides have one; without idx_runs_coordinator_actor the plan falls back to scanning every Run on each lookup. v42 is unreleased, so the index returns to migrate-v42 rather than needing a later schema step. * refactor(orchestration): store the Orca session id instead of an "actor" "Actor" read as a new concept when the columns only ever named a structured session. Rename them to what they hold: coordinator_orca_session_id (with its _generation), assignee_orca_session_id and creator_orca_session_id, plus the matching indexes, still added by migrate-v42 since v42 has not shipped. The columns now store the bare Orca session id rather than session:<id>. The session:<id> mail address is derived from ORCA_SESSION_ADDRESS_PREFIX where mail needs it: the coordinator address triggers and the cache refill share one SQL builder. isOrcaSessionId keeps refusing terminal-handle-shaped ids, and the generation rule and backfill evidence rules are unchanged. A dev database stamped v42 with the earlier *_actor columns replays the chain and gains the new ones. * fix(orchestration): remember every address a Run coordinator has, not the handle first The v42 coordinator triggers and the on-open refill stored one address, COALESCE(handle, session address), so a structured worker coordinator was remembered by its handle only. Remember each address the coordinator has, its handle and its current session address, each where present, so this cache follows the same rule as bindRun and no precedence is persisted. * docs(orchestration): define the Orca session id without a variable this change does not add The shared codec's comment named ORCA_AGENT_SESSION_ID, which nothing in this change defines, and ran one line past the wrap. It now says the stored id is the one the agent is addressed by (a /clear'd chat's lineage root), as the column comments do, and that PTY agents have none today rather than never. migrate-v42's note stated the lineage rule twice; it is folded into one sentence.
