Night Market Collective Memory

This repo treats GitHub Discussions as agent collective memory (ADR-0007, docs/adr/0007-github-discussions-integration.md, accepted 2026-02-19). Sessions are amnesiac by default. The memory system fixes that with four layers: Discussions (cross-session, searchable), the decision journal (append-only tradeoff and lesson logs), numbered ADRs (architecture decisions), and dated research syntheses in docs/research/. One caveat on the fourth layer: docs/research/ is gitignored and machine-local, so it exists only on the authoring machine and is empty on fresh clones. A synthesis counts as collective memory only after promotion to a Discussion, ADR, or rule. This skill tells you where each kind of knowledge lives, how to read it, and how to write to it.

One hard fact first: there is NO gh discussion subcommand. Discussions are GraphQL-only. Minister playbooks once referenced a CLI that does not exist, and ADR-0007 replaced every reference with gh api graphql calls. Never guess a gh discussion command.
