h-note

# h-note — Record a micro-decision You are recording a Note via the kernel. Notes are lightweight artifacts in the graph — they don't have the DRR ceremony but they do require rationale per FPF DEC-01 (no rationale-free decision capture). The Note tool lives under `haft_problem` action `select` does not write notes; the note-write surface is exposed through dedicated handlers in the MCP server. Check the actual tool name available — at present notes are written via the haft note CLI subcommand and via certain MCP integrations. ## Step 1 — Confirm intent The operator said something note-worthy. Before persisting: - Verify the note has substantive content: a fact OR a choice OR an observation with rationale - Reject: "FYI" alone, "we should remember this" with no payload - Accept: "We chose X over Y because Z" / "Observation: tests run 30s slower on M1 baseline since dependency update" ## Step 2 — Capture rationale explicitly Every Note must answer: - WHAT was decided / observed - WHY (the rationale) - WHEN (optional — kernel adds timestamp automatically; only add a domain timestamp if relevant) ## Step 3 — Persist Use the appropriate note-write tool. Currently: ``` mcp__haft__haft_problem( action="frame", problem_type="optimization", title="<short title>", signal="<the observation or choice>", acceptance="N/A — recorded as note for future recall", mode="tactical" ) ``` (Notes use the lightweight tactical-mode problem record OR a dedicated note write surfa...
