ACTIVE_CONTEXT.md

Baton, not journal. Volatile session state so a resumed or fresh session doesn’t re-derive it. Written before a context reset, read first on resume — then verified against live git log and item state, which win whenever they disagree with this file. Overwritten, not appended. Format: 08_lessons_and_memory.md.

Current focus

BL-0002 — tinker capture "<text>" with auto-attached context. Lock held by claude-sess-9d12, expires 2026-05-25T18:00Z.

Recent changes

• Arg parsing done via clap derive, following the recent subcommand’s pattern.
• cwd detection working; git-branch detection working inside a repo.

Next steps

1. Make branch detection degrade to None outside a git repo — currently it errors, which fails the item’s third acceptance criterion.
2. Write the capture test, including the cold p95 measurement.

Blocked on

Nothing right now — but the write path is a stub against BL-0005’s storage layer, which is blocked on a human decision. BL-0002 can be finished and tested against the stub; it cannot be marked done until the real layer exists.

Watch out for

• The 300ms cold budget is easy to blow from this item specifically, since everything here runs on the capture path. See the pinned memory entry capture-path-latency before adding anything inline.

Not here on purpose

Durable lessons (they go to memory/), decisions with lasting force (the item body or an architecture note), and anything the next contributor needs after this item closes. This file gets overwritten; none of that would survive.
