+## Anti-Pattern — Do Not Write "DOLCHEO+H"
+
+The vocabulary is **DOLCHEO**. The seven letters are D-O-L-C-**H**-E-O — Handoffs is the fifth letter, already inside the acronym. Writing **DOLCHEO+H** is malformed:
+
+- It doubles the H (once inside the acronym, once as the suffix).
+- It is residue from the superseded `OLDC+H` vocabulary (`docs/oddkit/proactive/oldc-h-vocabulary.md`), in which Handoffs were appended with `+H` because the original four letters did not include them. DOLCHEO absorbed Handoffs into the acronym; the suffix is no longer needed.
+- It propagates because agents see "OLDC+H" in canon-adjacent context (this doc's See Also, ledger headers in older artifacts) and pattern-match the suffix onto the new vocabulary by mistake.
+
+When tagging or describing session capture, write **DOLCHEO**. The Handoff section is named with the letter `H` inside the acronym, just like Decision is `D` and Encode is `E`.
+
+### If you are reading an older artifact that uses "DOLCHEO+H"
+
+Treat it as a typo equivalent to "DOLCHEO." Do not propagate the form into new artifacts. If editing the older artifact, correct it.
+
+### Receipts
+
+- `klappy/PTXprint-MCP/canon/encodings/pr-30-fresh-validator-ledger.md` line ~12 — contains "DOLCHEO+H encoding of findings." Marked here as the propagation source for at least one downstream session's hallucination chain.
+- 2026-05-03 slate-authoring session — agent propagated the form 8 times across two synthesis documents before operator correction. Direct stimulus for this anti-pattern callout.

+- **Notes**: Accepted in the same session that surfaced eight stuck `proposed` proposals (P0001 + P0003–P0009) sitting behind the just-merged P0002 promotion chain (PRs #163 → #165 → #166). The "DOLCHEO+H" hallucination is operator-named recurring frustration ("It's minor but I'm frustrated at it resurfacing every conversation"), and the proposed canon edit is a single appended section with one paragraph of net-new prose plus receipts — the smallest possible surface to kill the recurrence at the source. Accepted as drafted; execution committed in the same PR.
