 A push to any *other* remote carries no checkpoint data. `entire status` shows the current destination, where it came from, and how many checkpoints are unpushed. This matters if you push code to several remotes: checkpoints go to exactly one of them.
 
+When a repository has several remotes that could receive checkpoints, interactive first-time `entire enable` asks which one to use, after agent selection and before any hooks or settings are written. Re-running `entire enable` in an enabled repository does not ask again. Choosing a remote saves `strategy_options.checkpoint_push_remote` in `.entire/settings.local.json`, so teammates do not inherit a remote name specific to your clone; keeping the current destination writes nothing.
+
+To select a remote without the picker:
+
+```bash
+entire enable --yes --checkpoint-push-remote fork
+```
+
+The remote must already exist, and this is also how to change the destination later or repair a saved selection that names a missing remote. An explicit flag pins the named remote, even if it is currently selected automatically. `--yes` alone does not change the checkpoint destination. The command confirms the destination when you chose one or when the saved one is unusable; otherwise it ends at `Ready.` Selecting a destination does not re-enable disabled checkpoint pushing, upload existing checkpoints immediately, or move or delete checkpoint history from other remotes.
+
 If instead you want checkpoint data in a separate repo (e.g., a private repo for a public project), configure `checkpoint_remote` with a structured provider and repo. A dedicated `checkpoint_remote` is addressed directly and is exempt from the single-remote election above:

+//
+// plumbing.Hash is a struct carrying an object-format field alongside its
+// bytes, so == compares that field and .Equal (bytes.Equal over the array
+// alone) does not.
+//
+// At the pinned go-git the two cannot disagree, and that is worth stating
+// plainly so nobody "proves" this guard unnecessary by observing it: every
+// public constructor leaves the format unset for a 40-char hash and stamps
+// "sha256" only on a 64-char one — NewHash, FromHex, ResetBySize and
+// Hasher.Sum were each checked — so two hashes of the same object in one
+// repository always carry the same format. That is a property of the
+// dependency, pinned at an alpha, not of this code.
+//
+// It is also why this is a source guard and not a test. The mismatch is
+// unconstructible through go-git's public API, so no behavioural test can
+// distinguish the two operators: a call site reverted to == stays green. The
+// convention can only be enforced where it is written.
+//
+// The pattern covers a .Hash field or a .Hash() method call (Reference.Hash()
+// returns one) on EITHER side of the operator. The first version of this guard
+// matched only the left-hand side and so missed `stagedHash == shadowFile.Hash`
+// in content_overlap.go — in the file the guard was written for. Widening it
+// turned up five more in strategy/, so "the left-hand shape is all of them" was
+// not a small error.
+//
+// Two limitations, both deliberate:
+//
+//   - Two local variables compared directly (`if a == b`, neither spelled
+//     `.Hash`) need type information a textual guard does not have. That shape
+//     has no occurrences today, but unlike the ones above it cannot be ruled
+//     out by grepping.
+//   - It skips _test.go, matching the two sibling guards in this package. Note
+//     that assert.Equal on two hashes compares the format field too, via
+//     reflect.DeepEqual.
+//
+// Do not reach for \b or \s to tighten the pattern: git grep -E is POSIX ERE
+// and supports neither, so it matches NOTHING and the guard reports a clean
+// tree. Verified here — `\.Hash\b` found 0 lines in a file where `\.Hash`
+// found 20.
+//
+// A second family, `== plumbing.ZeroHash`, is NOT covered here and is not the
+// same severity: a 64-char zero hash carries format "sha256", so it is

 Workflow:
 1. Turn the question into one or more focused ` + "`entire search --json --compact`" + ` queries.
 2. Scan the compact hits: ids, files touched, score, the match snippet, and a truncated title — not the full prompt. Prefer checkpoint and commit hits; session hits are projections of the same checkpoints, so drill down through the checkpoint. Use inline filters like ` + "`author:`" + `, ` + "`date:`" + `, ` + "`branch:`" + `, and ` + "`repo:`" + ` when they improve precision.
-3. Explain the top one or two hits with ` + "`entire checkpoint explain <id>`" + ` (checkpoint ID or commit SHA). For a checkpoint hit from another GitHub repo, add ` + "`--repo <owner/name>`" + ` — it needs the full checkpoint ID from the compact hit, and only works for GitHub-hosted repos. For a session hit on the current branch, bridge with ` + "`entire checkpoint explain --session <id>`" + ` — it lists that session's checkpoints; explain one of those.
+3. Explain the top one or two hits with ` + "`entire checkpoint explain <id>`" + ` (checkpoint ID or commit SHA). For a checkpoint hit from another repo, add ` + "`--repo gh/<owner>/<repo>`" + ` for a GitHub mirror or ` + "`--repo et/<project>/<repo>`" + ` for an Entire-native repo — the forge prefix is required, and it needs the full checkpoint ID from the compact hit. For a session hit on the current branch, bridge with ` + "`entire checkpoint explain --session <id>`" + ` — it lists that session's checkpoints; explain one of those.
 4. Only if the scoped detail is not enough, add ` + "`--full`" + ` to pull the checkpoint's entire session transcript. It streams the whole transcript into context, so reach for it last and prefer another scoped explain first. For repo, pr, other-repo commit and session, and other-branch session hits, summarize from the compact fields alone; ` + "`explain`" + ` cannot read them.
 5. If nothing looks right, rerun a narrower ` + "`entire search --json --compact`" + ` instead of explaining many hits.
 6. Answer with the strongest matches, citing the relevant commit, session, file, and prompt details from the explained hits.

 2. **Metadata** is read from `entire-plugin.yml` at the repo root via a blobless shallow clone (with a plain shallow-clone fallback for servers that don't allow partial-clone filters). The file is optional; without it the plugin name derives from the repo basename (`entire-run` → `run`).
 3. **Asset download** is the one forge-specific step, contained in a small URL-convention table: GitHub/Gitea-style `<repo>/releases/download/<tag>/<asset>`, GitLab-style `<repo>/-/releases/<tag>/downloads/<asset>`, unknown hosts default to GitHub-style. Authors on other hosts declare a `download_url` template in `entire-plugin.yml` (placeholders: `{name}` `{tag}` `{version}` `{os}` `{arch}` `{asset}`).
 4. **Asset selection** goes through the release's `checksums.txt`: the manifest lists what was actually published, and the download is verified against it. Candidate names follow goreleaser conventions (`entire-<name>_<version>_<os>_<arch>.tar.gz` and friends, with `x86_64`/`aarch64` aliases and a `darwin_all` universal-binary fallback (`all` occupies the *arch* slot, which is where goreleaser puts it)). A pushed tag with no published assets falls back to the next-highest tag with a warning.

The dispatcher never changes.
 
 The manifest is written immediately after the binary swap and before the `bin/` link, which is ordering that matters rather than style. `replaceBinary` has already mutated `pkg/<name>/`; until the manifest catches up it records the *previous* tag and `binary_sha256` while the new binary is on disk, and `doctor`'s integrity check reads that as tampering — a permanent false alarm on a healthy install. Writing it first leaves only a local re-hash in that window, and if the link then fails, `doctor` reports the real problem ("has an install manifest but no entry in the managed bin dir") with a fix that works.

 Planning tracks the strictest `min_version` seen per plugin rather than a plain visited set. In a diamond where two requirers demand different minimums of the same plugin (A needs `sem >= v1.0.0`, B needs `sem >= v2.0.0`), a name-only set would mark `sem` handled on A's satisfied requirement and skip B's stricter one entirely — no action, no warning — completing the install with B running against a too-old `sem`. `doctor` caught that afterwards, since it walks each manifest's requirements independently, but the install plans the upgrade instead of deferring the discovery. One action per plugin name either way. The requirement list is copied into the install manifest so reverse-dependency checks work offline:
 
 - `entire plugin remove sem` refuses when another manifest requires it (`--force` overrides).
-- `entire plugin doctor` reports missing/outdated dependencies, manifest/bin-dir drift, binaries that no longer match the `binary_sha256` recorded at install, installs that were never checksum-verified, dangling local-dev symlinks, and (macOS) a `com.apple.quarantine` attribute that would block execution. Exit code 1 when issues are found. The integrity check covers the `pkg/` binary the manifest describes; where `bin/` holds a copy rather than a link (Windows without Developer Mode), the dangling/non-executable link check is what guards that surface.

Exit code 1 when issues are found; a `note:` line (a `bin/` entry that a local `plugin install <path> --force` replaced) is informational and does not affect the exit code. The integrity check covers the `pkg/` binary the manifest describes and any `bin/` entry that is not that same file; every `bin/` entry is also checked to be runnable (not dangling, unfollowable, a directory, or empty).
 
 > **Compatibility note:** the `entire plugin` command group is itself a built-in. Per the "built-ins win" rule above, it shadows any external command named `entire-plugin` that may have existed on `$PATH` previously. The collision is intentional — managing plugins is a built-in concern — but worth flagging for anyone who shipped an `entire-plugin` external command before this layer landed.

@@ -451,6 +451,33 @@ For the fork setup where `origin` is an unpushable base repo, capture elects
 the fork automatically on the first tracked push; `checkpoint_push_remote`
 remains the explicit override.
 
+`entire enable` offers a named-remote picker during interactive **first-time**
+setup when multiple remotes need resolution. It uses the existing election and
+destination checks; it does not introduce another election tier. Keeping the
+current selection writes no override — which is why a bare re-enable in a
+configured repo never prompts: the conditions would be unchanged on the next
+run, and there would be no way to say "stop asking" short of pinning a remote.
+Selecting a different remote, or supplying `--checkpoint-push-remote <name>`
+(the path for changing the destination later, and for repairing a saved remote
+that no longer exists), persists an explicit override in the clone-local
+settings file. The write preserves unrelated settings and is verified through
+the effective settings loader before reporting success. On fresh enable, agent
+selection precedes remote selection; both happen before hook/settings setup
+side effects. Persistence happens after setup's settings saves but before
+destination-dependent checkpoint initialization.
+
+The picker is skipped for valid explicit or elected dedicated destinations,
+disabled checkpoint pushing, a rejected local settings layer (the choice could
+not be saved), and non-interactive invocations; `esc` at the picker means the
+same as keeping the current destination. An explicit remote flag is still
+honored without prompting and does not enable disabled pushing. Destination
+selection does not migrate, publish, or delete existing remote checkpoint data.
+Alternatives that still resolve to dedicated storage are not offered as
+ordinary named destinations. The closing destination report is printed only
+when the destination was touched (explicit flag, picker shown, or
+`--checkpoint-remote`) or is unusable; a healthy destination nobody asked about
+ends at `Ready.`, and the multi-remote ambiguity note covers the rest.
+
 The pre-push hook carries checkpoint data only when the push targets the
 elected remote; pushes to any other remote or to a raw URL sync nothing, on
 both the git-branch and git-refs backends (git-refs leaves its push queue

+## Control-Plane Tests
+
+`controlplane/` runs the `entire` binary against the production control plane with no coding agent involved. Its `TestMain` logs in once per run with `entire login --device`, completing GitHub sign-in and the device approval in headless Chromium (playwright-go) as the GitHub test user named by `E2E_GH_USERNAME` / `E2E_GH_PASSWORD` / `E2E_GH_TOTP_SECRET`; every test then starts from that session. The account has authenticator-app 2FA enabled on purpose: GitHub skips its emailed new-device verification for 2FA accounts, and the test computes the one-time code from the secret. The CLI's config and token store live in a temp dir outside `e2e/artifacts/`, which CI uploads.
+
+Tests create real resources named `e2e-cp-<timestamp>` and delete them in reverse order (repo, project, org) through `t.Cleanup`. The test account may own at most three orgs, so a run that is killed before cleanup (package timeout, cancelled job, lost runner) would block later ones; each run therefore starts by sweeping `e2e-cp-*` orgs older than 30 minutes, and everything under them.
+
+Run it with `mise run test:e2e:controlplane [filter]`; the task installs the Playwright driver and Chromium on first use.
