+# Tick 2026-05-16T09:22Z — Otto-CLI
+
+Fortieth tick of the resume-session series. Rate healthy
+(3329/5000). Audited B-0314 — **self-documenting partial,
+class-#2 sub-variant**. Row has explicit slice-progress table
+showing 9/28 BP rules anchored. NO Status section needed.

+## Audit: B-0314 — self-documenting partial
+
+[B-0314](../../../../../backlog/P1/B-0314-bp-nn-rule-anchor-backfill.md)
+(`BP-NN rule external-anchor backfill`). Single artifact:
+`docs/AGENT-BEST-PRACTICES.md`.
+
+**Done-criteria check** (zero gh):
+
+- ❌ All 28 rules anchored — **9 of 28 done** per slice-progress table
+- ❌ Citations include URL/author/title/date — partial
+- ❌ Beacon-safety pass — partial
+- ❌ Coverage scanner (B-0311) confirms 28/28 — incomplete
+
+Row has explicit "Slice progress" table showing exactly which BPs
+are anchored (BP-10, BP-11, BP-03, BP-07, BP-16, BP-04, BP-08,
+BP-09, BP-12 = 9 of 28). **Self-documenting** — the partial state
+is visible to any reader.
+
+**NO edit needed**. Same self-documenting pattern as B-0440 +
+B-0441 (bg-service class-#3) and B-0312/B-0537 style trackers.
+
+## Pattern: "self-documenting" cuts across drift-classes
+
+The taxonomy now has TWO axes:
+
+**Axis 1: Drift class** (1 / 2 / 3 / 4 / FP-2 / FP-3)
+
+**Axis 2: Documentation completeness**
+
+- **Opaque**: row has no progress indicator; partial state invisible
+- **Self-documenting**: row has slice-status table / checkbox tracker / similar
+
+Self-documenting class-#2 (B-0314, this tick) + self-documenting
+class-#3 (B-0440, B-0441) all share the same disposition: **NO
+edit needed**; the partial/in-progress state is already visible to
+any reader running the row-close gate triage.
+
+**Implication for audit cadence**: when a row has a progress
+indicator, the audit-tick can be ~30 seconds (existence-check +
+read progress section) instead of multiple minutes (read full
+acceptance + edit-Status-section + commit + push + PR + arm).
+~10× cheaper per audit.
