v0.18.1

Zero-weight release from the first Fable 5.1 review of the methodology (three-analyst council,
harness D-027): one hook fix and a batch of doc claims brought back in line with their sources.

Fixed

• Boundary hook splits ·- and ;-separated EDIT BOUNDARY bullets (bin/lcd-hooklib.sh),
  the same class as the v0.15.1 comma fix — a bullet like `a.md` · `b.md` was matched as
  one literal path and silently denied every file it listed. Fixture case added (#17).

Changed (docs only)

• Dropped "most work is Quick" (triage SKILL, docs/why-lcd.md): the dogfood log reads
  3 Quick / 12 Standard / 3 Deep and trivial work skips triage by design, so the claim was
  neither measured nor measurable. The lanes stand on resumability.
• Dropped "denser tokenizer on newer model tiers" (README, rules/lcd.md, docs/why-lcd.md):
  the +30% tokenizer arrived with 4.7 and is shared by Fable 5 and 5.1 — not a tier property.
• "~2k tokens to resume" is now stated as a target, not a result (README, rules/lcd.md, triage
  SKILL, docs/why-lcd.md); it has not been measured.
• The edit-boundary hook's guarantee is scoped honestly (README, rules/lcd.md): it sees
  Edit/Write-family calls only; Bash-tool edits pass it. Deliberately not extended to Bash
  (shell parsing either misses cases or over-denies and breaks fail-open).
• README "Self-measuring" now publishes the measured numbers with their caveats: Deep ~4.4× and
  Standard ~2.1× a bare agent at near-parity single-shot quality (n=3, one fixture,
  claude-fable-5); the cross-session half is the open measurement (#16).
