+### Arc 12 — Roadmap item #23 surfaced: rename transcripts to numeric form
+
+Right after arc 11's re-publish, the operator surfaced another
+ask: "Add renaming transcripts from e.g. SESSION-A to SESSION-0001.0
+etc to the roadmap." This is roadmap item #23 (Track Ω, operator-
+led, one-session operational gesture):
+
+- **New convention**: `SESSION-NNNN.M-TRANSCRIPT-<start>--<end>.md`
+  where `NNNN` is a zero-padded 4-digit session number and `M` is
+  the subagent ordinal (`.0` = main driver, `.1+` = subagents).
+  Nested as `.M.N` for sub-subagents.
+- **Mapping**: A → `SESSION-0001.0`, B → `SESSION-0002.0`, …,
+  L → `SESSION-0012.0`. Twelve existing transcripts in
+  `wiggleverse/ohm-session-history` to rename, plus the local
+  `~/git/ohm-infra/` copies.
+- **Surfaces touched** (enumerated in the item): the public repo
+  (git mv per file for history preservation), local working dir,
+  SESSION-PROTOCOL.md §1 + §5 + worked examples, publish-
+  transcript.sh filename validator, flotilla CLAUDE.md
+  references, ohm-rfc/ROADMAP.md shipped-row references in the
+  table, cross-transcript body links (Session-K-to-Session-I
+  etc.).
+- **Open questions enumerated in the item**: git-mv vs.
+  add+delete (preserve history); redirect tombstones vs. 404
+  (URL breakage for external references); sequencing relative
+  to the next-letter-after-L session (most-elegant timing is
+  Session M as the rename session itself, so `SESSION-0013.0`
+  debuts as the new shape from the start). Decide at session
+  time.
+
+Committed to ohm-rfc at `8cce148` with a 130-line item
+description + a single-row addition to the version-targets table.
+
+### Arc 13 — Re-finalize + re-publish (again)
+
+Per the same discipline arc 11 named: the operator's #23 ask
+landed after the first re-publish, so this triggers another
+finalize-and-republish cycle. This arc 12+13 added; cut-state
+table updated to reflect ohm-rfc at `8cce148` and the third
+finalization pass; re-published.
+
+If a fourth operator instruction lands after this publish, the
+cycle continues. The discipline holds open-ended.
