+Ferried `endojs/endo-but-for-bots#68` (Compartment availability and OOM
+limits docs) upstream as a new non-draft PR on `endojs/endo`.
+
+- Upstream PR: <https://github.com/endojs/endo/pull/3275>
+- Upstream PR number: 3275 (non-draft, OPEN).
+- Upstream branch: `kriskowal-compartment-oom-docs-2742` (first-push via
+  `git push origin HEAD:refs/heads/kriskowal-compartment-oom-docs-2742`).
+- Upstream head SHA: `4d8ed6be74c861472a85df3f38af7081f1d6689c`.
+- Base: `master` at `bf951df346cfcf605a6709e6a5479f2fdd526113`.
+- Closing keyword: `Closes: #2742` in the PR body; `Fixes #2742` in the
+  commit message.
+
+Source-side: cherry-picked 4 of the 5 commits on
+`endojs/endo-but-for-bots@design/issue-2742-compartment-limits-doc`
+(source head `838d18ff9bae5bd6d16032efb8f0c575e079ef68`) with
+`--no-commit` into a single squashed commit, skipping the off-topic
+`cb8d6286` AGENTS.md em-dash rule (which is unrelated to issue #2742;
+a future ferry can carry it).
+
+Picked: `8a1fc626`, `59957425`, `f299f8e4`, `838d18ff`.
+Skipped: `cb8d6286` (AGENTS.md).
+
+Tree-identity verification (with AGENTS.md exclusion):
+
+- `git diff origin/master..HEAD --name-only` lists exactly
+  `docs/lockdown.md` and `packages/ses/README.md`.
+- `git show 838d18ff:docs/lockdown.md` is byte-identical to
+  `git show HEAD:docs/lockdown.md`.
+- `git show 838d18ff:packages/ses/README.md` is byte-identical to
+  `git show HEAD:packages/ses/README.md`.
+- `git show HEAD:AGENTS.md` is byte-identical to
+  `git show origin/master:AGENTS.md` (commit 3 correctly excluded).
+
+Attribution and trailer discipline:
+
+- `git log origin/master..HEAD --pretty=fuller` shows one commit, both
+  author and committer `Kris Kowal <kriskowal@kriskowal.com>`.
+- `git interpret-trailers --parse` on the commit message is empty: no
+  `Co-Authored-By:`, no `Generated with [Claude Code]` line, no
+  Kriscendo Bot residue. Particularly important here because the carried
+  content from `f299f8e4` was originally authored by Kriscendo Bot; the
+  squash rewrites attribution to Kris Kowal and drops the bot trailer.
+- The `(#68)` source-branch suffix on commit 5's subject was subsumed
+  by the squash. The "address review" framing from commit 2 was
+  dropped. The new subject is verbatim from commit 1:
+  `docs(ses): document Compartment availability and OOM limits (#2742)`.
+
+PR body uses the endo PR template section headings verbatim
+(Description, Security, Scaling, Documentation, Testing, Compatibility,
+Upgrade Considerations). Behavior over diff. No checklists. No file
+callouts beyond the load-bearing `docs/lockdown.md` (Limitations
+section) and `packages/ses/README.md` (Compartment cross-link). No
+methodology leak. No reference to the source PR, the
+`endo-but-for-bots` fork, or any garden artifact.
+
+Identity discipline: no direct comments posted on the new upstream PR.
+The only cross-link comment is on the source-side PR
+`endojs/endo-but-for-bots#68`
+(<https://github.com/endojs/endo-but-for-bots/pull/68#issuecomment-4505381907>),
+naming the upstream URL, the head SHA, the 4-of-5 squash with the
+explicit `cb8d6286` AGENTS.md exclusion, and the `Fixes #2742` addition.
+
+Self-improvement: tree-identity verification when the squash is
+relative to a different base than the source's base (here, source was
+based on a months-older `master`) cannot be a single
+`git diff source HEAD -- . ':!excluded'` because that pulls in every
+unrelated change between the two bases. The reliable form is a
+per-file `git show source:path` vs `git show HEAD:path` byte
+comparison on exactly the files the squash touches, plus a check that
+the excluded file's HEAD content equals the base's. Worth lifting into
+a `pr-handoff` skill the next time a boatman ferries with exclusion.
