Description
The committed baseline is worthless if it came from a sampled scan: sampling cannot prove a shape is absent, so a baseline built that way records absences that are really just misses.
Acceptance Criteria
- #1 The baseline is produced by a full scan across every namespace, never a sampled one
- #2 The committed signature passes the content-freeness test
- #3 just probe is clean against the sample the baseline was built from
- #4 The corpus sample used is described in the task notes by shape and date range, never by content
- #5 just baseline may be run without asking, including non-interactively; the standing constraint is that the scan behind it is full and never sampled
Definition of Done
- #1 just check passes: fmt-check, lint, build, test-short, probe-ci, dashboard-check and docs-links all clean
Implementation Notes
Rob authorised just baseline unconditionally on 2026-09-22, for this wave and every future one. AGENTS.md updated in the same change. The ask-first gate that AC #2 originally carried is gone; the full-versus-sampled constraint is the one that still matters, because a sampled scan records absences that are really misses.
