Summary

Adds anti-patterns 14–19 to workstreams/RESEARCH_DOCUMENTATION_WORKSTREAM.md, surfaced during an editorial audit of a 16-paper, ~5,930-line research-documentation corpus that applied this workstream's Audit Mode. Each new pattern is grounded in concrete findings from that audit; none overlap the existing 13.

The new anti-patterns

#	Name	Distinct from
14	Companion-paper drift — extracts diverge from sources over time	KJ5HST#9 (edit from memory, within-session) — this drift is across-time
15	Stale verification artifact — verification reports lose coverage as targets evolve	(new dimension — no overlap)
16	Date-anchored prose without timestamp — "as of early 2025" silently ages	#1 (citation drift) — this is narrative tense, not citation keys
17	Multiple-bibliography drift — per-cluster .bib files diverge from canonical	(names the failure of the existing Phase 3 "single bibliography" rule)
18	Verification-flag / body-text divergence — flag exists but doesn't propagate to body	#6 (descriptive-page substitution) — the source-quality issue is identified, it just doesn't reach the body
19	Scope-overlap silence between sibling papers — papers share evidence with no cross-reference	KJ5HST#12 (redundant restatement) — this is across-paper, between artifacts that consciously chose to be separate

Format

Each addition follows the same "name — symptom — mitigation" form as the existing 13. The Audit Mode "Severity calibration" table (Critical/Moderate/Minor) is updated to reference the new anti-patterns by number.

Provenance

The originating audit is preserved in the project where the patterns were observed: rmsharp/model_governance:docs/audits/20260425_qmd_corpus_audit.qmd. That audit produced 55 findings across 16 papers; the 6 patterns proposed here each had multiple supporting findings in that report. References to specific findings are in the local commit message.

Test plan

• Markdown renders cleanly (no broken table syntax)
• Anti-pattern numbering is contiguous (1–19)
• Severity calibration table references all 6 new anti-patterns by number
• No regression to the existing 13 anti-patterns or to other sections

Closing — work landed directly on main as commits 557a89e (add 6 anti-patterns) and 6d9833e (fix anti-pattern count in audit-mode mapping table). The PR was bypassed in favor of a direct merge.
