v0.4.23

Patch — the defrag detector flags flow, not stock (the footnote polish).

Two dream-session footnotes root-caused (docs/defrag-flow-and-emoji-index.spec.md
— advisor + adversarial review-to-zero, amend-1/2):

• P1 — the defrag re-nag: defrag_candidates flagged every fact with a body

  2.5× the store median — a structural property of any roadmap, so a KEEP'd doc
  re-nagged every dream. The --justify-defrag watermark (defrag_justify in the
  state file, REFRESH semantics — never the demotion skip-if-present no-op, which
  would re-anchor the very re-nag) quiets a justified stem until it genuinely
  grows (+40 tokens AND +25%, malformed entries fail open); the Phase-0 report
  shows the watermark line independent of the candidate count; --force is the
  post-curation re-anchor repair. The justify collectors stop at an existing
  directory — the demotion sibling's trailing-project-dir swallow, same class.

• P2 — the emoji flag names its beat: ⚠ emoji in beat(s): 3 (1-based, the
  archive's Passage numbering).
• P3 — the debrief discipline: claims about the rendered archive are verified
  against the rendered file (the log line is attempt-scoped).

Smoke 1762/0 (+13 pins — 8 discriminating vs the merge-base, 5 semantic regression guards), mypy clean, sim, manifests, browser 1108.
