Why: Card registration or transcript persistence failures must not orphan paid work or discard a generated result, and ordinary questions must not match summary requests.
Evidence: Registration/promote and message-insert fault regressions, implicit-question checks and scoped race tests pass; legacy projection caching preserves historical times.
Impact: Fail before execution when tracking is unavailable, preserve full public final text with an explicit failure state, cache legacy projections once, and repair the concurrent material test fixture.
Refs: feature/workbench-flow-completion independent review closure
Why: Background notice runs blocked chat, truncated results, and duplicated deliverable execution.
Evidence: Focused run manager, card, server, recovery and race regressions pass locally; final combination checks are tracked in Dev.
Impact: Persist full results and optional choices, fence dispatch by run identity, retain public child process, and repair legacy projections without a schema change. No paid model trial was run.
Refs: feature/workbench-flow-completion
Why: Stop showing raw task text as progress and stop lighting the
done lamp on failed background runs (U1 whitelist).
Evidence: go test ./internal/runmgr/ -count=1
Impact: create/promote/finish card bodies; material queue status text.

Why: TestMaterialIntakeAttachmentOnlyLifecycle flaked when waiting on
systemTexts; deliverNotices runs before defer materialKeyRelease, so
done-dedup still saw the in-memory key and returned pending.
Evidence: go test ./internal/runmgr/ -run TestMaterialIntakeAttachmentOnlyLifecycle -count=20
Impact: Aligns the wait with materialExisting gates; no production change.

Why: at the 3-per-conversation cap the guaranteed material task was dropped silently, and long deliverables stayed in chat because cardflow defaulted off (user ruling 2026-10-11).
Evidence: new queue lifecycle test (queued card, hard-reject for model path, FIFO start on release, card promote) passes; full go test ./... exit 0 (local, SELF).
Impact: queueable system spawns create a queued progress card at capacity and start FIFO when a slot frees (memory-only queue; restart limitation noted); model delegate_task still hard-rejects; ui.cardflow default true (EffectNewRun).
Refs: Dev task .task/feature-material-intake-flow.md I3.
Why: after material organization completes, weak models report and end the turn without offering the user a choice of formal deliverables, and even after a user picks one the model may close the turn without starting the background task.
Evidence: new tests (notice-choice chain, deliverable backstop, free-input path, invalid args, notice contract) pass; full go test ./... exit 0 (local, SELF).
Impact: new confirm_choice tool issues a HITL choice card and routes the answer into a hard delegate instruction; material notices instruct the model to report then offer choices; stop hook adds two one-shot backstops (choice not offered in material notice runs; choice made but no background delegation).
Refs: Dev task .task/feature-material-intake-flow.md I2.
Why: the dual-speed entry hint is advisory only; real runs (MiniMax, 3 attachments, no text) end with a clarifying question and zero delegation, so background cards and result backfill never start.
Evidence: new unit tests in runmgr/material_test.go and runtime/material_flow_test.go all pass; full go test ./... exit 0 (local, SELF).
Impact: attachment-carrying runs now guarantee a material-organization background task (pre-spawn on attachment-only/heavy sends, stop-hook backstop otherwise when the model did not delegate); subagent receives inline parsed text with budget plus knowledge_search guidance; content-key dedup prevents duplicate spawns (in-flight, completed, resend); model-authored delegate_task gains a materials appendix; settings runtime.materialIntake (default on) and runtime.materialIntakeChars added.
