These columns and the messages that plumbed them existed for the CLI-
adapter era — Gemini's resume id and provider-specific session params
rode the run-finished envelope back onto the session row so the next
turn could resume. Pi Mono dispatches every provider through pi-ai and
emits neither value. The worker has been posting literal null on every
finish, finalizeRun has been writing null into task_sessions, and
rotateSession has been carrying null forward.
Remove the wire, the writer, the carry-forward, and the columns:
- v43 migration rebuilds task_sessions without session_params_json /
session_display_id, and runs without session_display_id. Follows
the idempotent "create new, copy, swap, reindex" pattern used by
v41. context_snapshot_json is preserved (also unreferenced today
but outside this cleanup's scope).
- RunJob / EnqueueRunPayload / ChildMessage / worker-types zod
schema no longer carry the fields. finishRun() / createNewSession()
signatures tighten in lockstep.
- rotateSession starts the new session with fresh counters and no
carry-forward.
- turn-context resolveSession returns just the session id.
- TaskSessionRecord / RunRecord lose the dead fields.
498/498 unit tests pass. typecheck + build clean.
- Add required `roleLevel` to dashboard-charts and prompt-manager fixtures
so they satisfy the AgentRecord contract.
- Replace legacy "anthropic" connectorId with `claude_local` in
approval-hook fixture to match the current `ConnectorId` union.
- Install recharts@3.8.1 as dependency
- Create chart-utils.ts with 4 exported pure functions: aggregateRunsByDay, aggregateCostsByDay, aggregateAgentWorkload, formatShortDate
- Create dashboard-charts.test.ts with 16 unit tests covering all aggregation behaviors
- All tests pass: 14-day bucketing with zero-fill, timed_out/interrupted as failed, null cost handling, top-8 + Others grouping, name truncation
