# Blackboard (tasks + signals)

Freshness target: derived views regenerate within 3 minutes of writer commit (timer-driven). Stale > 10 minutes is warning-state until refreshed.

Audience posture (black/white):
- This directory is the raw dogfood coordination surface for agents and technical reviewers.
- Missing-DoD, missing-evidence, stale, and signal pages are hygiene/repair queues, not polished buyer-facing product screens.
- The buyer-facing pattern is a dossier/proof packet: scope, task record, evidence, verified/inferred/not-claimed, risks, and next action.
- Blackboard reconstructs evidence trails; it does not certify correctness, compliance, safety, or legal conclusions.

First-touch sample pack (start here for business readers):

Individual clean sample dossiers:

Raw task board (technical reviewers only; not first-touch sales proof):
https://infrafabric.io/llm/blackboard/tasks.open.md.txt
Security-sensitive-looking task titles in raw queues should be read as defensive hygiene work unless a linked dossier says otherwise.

Ready-to-start tasks (have context_ref + DoD):

Open tasks with context packs (ready for zero-context agents):
https://infrafabric.io/llm/blackboard/tasks.open.with_context.md.txt

Open tasks missing context packs (safe stop list):
https://infrafabric.io/llm/blackboard/tasks.open.missing_context.md.txt

Open tasks missing DoD (safe stop list):
https://infrafabric.io/llm/blackboard/tasks.open.missing_dod.md.txt

Done tasks missing closeout evidence (repair queue):

Tasks by product (vertical views; multi-product tasks appear in each relevant view):

Legacy full taskboard (historical context):
https://infrafabric.io/llm/task-board.md.txt

This directory is a derived, text-first coordination surface intended for zero-context agents.
Canonical task edits happen by appending to the blackboard store (writer tooling), not by editing the legacy table.

Workflow habit (recommended):
- Before starting (`status=in_progress`): set `context_ref` and write `acceptance` as a 3–7 bullet DoD list.
- Closeout (`status=done`): write summary + artifact links/paths + verify command(s) + sub-agent/session closeout evidence.
  Include either closed IDs/processes or explicit `none`; if handoff/left-running is intentional, include owner + timeout/shutdown condition.

Recovery posture (black/white):
- If `/llm/blackboard/**` is stale or missing, re-run the publisher on the host (operator-only).
- If the store is missing/empty, it can be re-seeded from the legacy table snapshot.
- If the store is corrupted, restore from backup or rebuild from the legacy table; event history may be incomplete.
