+## After a PR merges (re-slice protocol)
+
+When an upstream PR squash-merges (e.g. PR #1286 -> `2aaeee2a` -> main):
+
+1. **Backup** the current stack tip:
+   ```bash
+   git branch will/ltx2_sr_port-pre-<PR>-rebase will/ltx2_sr_port
+   ```
+2. **Fetch** new main:
+   ```bash
+   git fetch origin main
+   ```
+3. **Identify dropped commits.** A squash merge has a unique patch-id
+   different from any individual commit, so `git cherry` won't auto-detect.
+   List the SHAs that were squashed (typically 3-4 commits — the original
+   PR's individual commits plus any cherry-picked polish):
+   ```bash
+   git log --oneline origin/main..will/ltx2_sr_port | head
+   # Identify which top-of-chain commits match the merged PR's content.
+   ```
+4. **Interactive rebase dropping those commits:**
+   ```bash
+   GIT_SEQUENCE_EDITOR="sed -i \
+       -e '/^pick <sha1>/s/^pick/drop/' \
+       -e '/^pick <sha2>/s/^pick/drop/' \
+       -e '/^pick <sha3>/s/^pick/drop/' \
+       -e '/^pick <sha4>/s/^pick/drop/'" \
+     git rebase -i origin/main will/ltx2_sr_port
+   ```
+   Expect zero conflicts when the dropped commits are isolated to a
+   subdirectory (router code, in PR #1286's case) — the surviving
+   commits don't touch those paths.
+5. **Re-slice split branches** to new boundary tips (see "New linearized
+   chain" in [state.md](state.md) for the slice index table — each
+   "Tip SHA" column maps to a `git branch -f <branch> <sha>` call):
+   ```bash
+   git branch -f will/api_<next>          <slice-N-tip>
+   git branch -f will/api_<next+1>        <slice-N+1-tip>
+   ...
+   ```
+6. **Verify** with the test suites in "Verification" below.
+7. **Force-push** the working branch (one force-push, requires explicit
+   user confirmation per [`AGENTS.md`](../../../AGENTS.md)):
+   ```bash
+   git push --force-with-lease origin will/ltx2_sr_port
+   ```
+8. **Push the next slice** as a new remote branch (no force, just `-u`):
+   ```bash
+   git push -u origin will/api_<next>
+   ```
+9. **Open the next PR** via `gh pr create --base main --head will/api_<next>`.
+10. **Update memory dir** — bump `Last reconciled` headers in
+    [README.md](README.md) / [state.md](state.md), promote PR rows in
+    [pr-roadmap.md](pr-roadmap.md), update Item D state in
+    [open-threads.md](open-threads.md), refresh [authors.md](authors.md)
+    verification table.
+
+The post-#1286 rebase (2026-05-05) followed exactly this protocol — see
+[state.md](state.md) "Post-#1286 rebase summary" for what dropped and
+the new slice indices.

 FastVideo worktree default branch is `will/ltx2_sr_port`. Other agents
 share this worktree — if `git branch --show-current` shows something
 else, switch back cleanly with `git checkout will/ltx2_sr_port` (don't

+## Historical commit chain analysis (pre-#1286 rebase)
+
+The layered chain analysis below documented the pre-rebase SHAs (LTX-2
+SR layer, NVFP4 layer, post-handoff fixes layer). Those SHAs no longer
+exist on `will/ltx2_sr_port` — they live only on
+`will/ltx2_sr_port-pre-1286-rebase`. Content semantics are unchanged;
+SHAs were rewritten by the rebase. Kept here for narrative continuity.
