Noted un-back-merged release chores beyond A3: e65796f (SC1091 lint silence) — left for a future reconcile.
+- Full back-merge release/1.0.0→develop (`chore/backmerge-release-full`, unmerged): the RC fork had left ~6 functional fixes orphaned on develop, silently. PORTED via cherry-pick, make test green each: `095d881` drop find-skills, `a1093ca` make-update TTY-guard (proven: EOF-die exit1 → guarded exit0), `4c5e862` rtk update-path version-guard (complements the `e58037c` install bridge already ported), `c76479f` design-motion sync, `e65796f` SC1091 lint. B soak journal (find-skills day1 / TTY #3 / rtk-update #4) folded here, not cherry-picked — divergent journal tails conflict (STOP-on-conflict honored, extract-consolidate fallback). C all covered/skip: `93e43c0` attribution + `ae8ad86` model already on develop; `188a9a7` docs → /doc backlog (README missing semgrep/scan-secrets/verify+secure/ctx7). Registry (LRN-098/101, EVAL-015, BLK-016) already backfilled in the review run. Gate: 23/23 release-only commits classified, 0 orphan functional, 0 missing registry; make test GREEN, review-guards 5/0. version.txt stays 4.0.0 (fork intentional, D — `eb93050`).
+- [[LRN-117]]: the fork silently orphaned functional CODE on develop (not just memory); the review back-merge caught ~half. Detecting it needs a code-level drift check (advisory, backlogged) — registry-sequence gaps alone miss it.

+## LRN-117 — A release/develop fork silently orphans functional CODE on develop, not just memory
+- **pattern**: cutting release/1.0.0 and continuing on develop, the RC-branch bug fixes (find-skills drop `095d881`, make-update TTY guard `a1093ca`, rtk update-path version-guard `4c5e862`, rtk install bridge `e58037c`, SC1091 lint `e65796f`) landed ONLY on release. They were live-broken on develop for the whole fork duration (rtk compression dead, `make update` dies non-interactively). The review's memory back-merge caught the registry gaps and one code fix (rtk bridge); a full back-merge found ~5 more functional commits.
+- **why it hides**: registry-sequence gaps (missing LRN/BLK/EVAL ids) are easy to detect; orphaned CODE has no sequence to check. A feature can be parallel-merged to both branches while an RC-branch fix commit is never back-merged, and nothing flags it.
+- **fix**: at release-finish / in /reconcile, list `develop..release/*` commits touching functional files (exclude merges, `.claude/**`, version.txt/CHANGELOG) and present them for back-merge review. Advisory, NOT a hard make-test gate — cherry-picks land with new SHAs so the source commit stays in the range; automatic "already-ported?" equivalence is unreliable and would false-positive. Backlogged.
+- **future application**: any long-lived fork (release/*, long feature) — audit CODE divergence, not just declared/registry state ([[LRN-034]] narrated ≠ ground truth, applied to branches).
+- **cousin**: [[LRN-116]] (a resolved blocker's fix can be missing from develop), [[BDR-054]] (supersession-trace discipline).
