For a checkpoint hit from another repo, add ` + "`--repo <owner/name>`" + ` for a GitHub mirror or ` + "`--repo et/<project>/<repo>`" + ` for an Entire-native repo — 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.

 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 several remotes need a choice, interactive `entire enable` offers a remote
+picker, including when you re-run it in an enabled repository. Keeping the current
+destination leaves its selection unchanged. During first-time setup, agent
+selection comes before the remote picker; both precede hook and settings changes.
+Choosing another remote saves
+`strategy_options.checkpoint_push_remote` in `.entire/settings.local.json`, so
+teammates do not inherit a remote name specific to your clone. Valid explicit
+selections and effective dedicated checkpoint repositories are preserved.
+If a saved selection names a missing remote, the picker offers eligible remotes
+to repair it; keeping the invalid selection leaves checkpoint sync disabled.
+
+To select a remote without the picker:
+
+```bash
+entire enable --yes --checkpoint-push-remote fork
+```
+
+The remote must already exist. 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 effective destination and any
+local settings write. 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:

@@ -451,6 +451,24 @@ 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 setup or
+re-enable 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. Selecting a different remote, or supplying
+`--checkpoint-push-remote <name>`, 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, and non-interactive invocations. 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.
+An invalid saved remote can be repaired interactively. Alternatives that still
+resolve to dedicated storage are not offered as ordinary named destinations.
+
 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

Subject: [PATCH 13/74] fix(explain): name the supported agents for an unusable
 summary provider

summary_generation.provider takes names out of the agent registry, and
every name in that registry is also a valid `entire enable --agent`
value, so writing the agent you code with into it looks right. For
opencode and factoryai-droid -- registered agents with no GenerateText
-- the whole diagnosis was "agent opencode does not support summary
generation": no accepted values, and no pointer to where the value
lives.

Neither writer can produce such a value (configure --summarize-provider
validates, and the picker's candidates are capability-filtered, a filter
present since the feature's first commit), so it always arrives by hand
editing. And nothing said so: Validate() checks only
model-without-provider, `entire status` never mentions summary
generation, and the error surfaces at `checkpoint explain --generate` /
`dispatch` / `runner setup`, possibly weeks after the edit.

The three "does not support summary generation" sites now route through
unsupportedSummaryProviderError, which lists the capable agents derived
from the registry so a stale name cannot outlive the capability. It is
deliberately not $PATH-filtered: it answers which names the field
accepts, and the PATH condition keeps its own error.

entire doctor gains checkSummaryProvider, which reports the condition
without fixing it -- the value may live in a committed settings.json
where a rewrite changes everyone's configuration. An unregistered name
and an off-$PATH binary are deliberately not reported; see the call site
for why.

Both walks, the doctor check and the error paths share one capability
probe, summaryCapableAgent, so the predicate cannot drift between them
-- AsTextGenerator consults CapabilityDeclarer for external agents,
which is the part an inline copy gets wrong.

Subject: [PATCH 14/74] review: name the explicit checkpoint remote and cover
 the pinned case
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses the four review comments on trail 1272.

Rename `selected` to `explicitRemote`. The field holds only the
SyncRemoteSourceConfig tier, but the codebase already says "elected" for
the resolver's all-five-tier value, so `selected` read cold at
fanOutMatters invited reading it as "wherever checkpoints go" — the
reading that makes the deliberate `observed` suppression look like a bug.

Document the states that leave it empty. It is not only "nothing explicit
is configured": ResolveCheckpointSyncRemote also errors when
checkpoint_push_remote names a remote that is not configured (fail-closed,
checkpoint sync disabled entirely) or when settings are unreadable, and
all three collapsed into one empty string with only the first named.

Cover the selected-and-pinned interaction. The table exercised `selected`
against fan-out in four combinations but never set `pinned`, so the term
that suppresses the warning had no case. A dedicated checkpoint_remote
only takes effect when origin and every push URL of the push remote share
the checkpoint repo's owner (checkpointRemoteIsInherited), so the case
needs owner-aligned remotes rather than the fork-of-upstream shape the
other cases use. Guarded against passing vacuously by asserting the
fixture really pins a fanning-out fork; removing the !d.pinned term from
fansOut() makes the case fail with the spurious two-URL warning.

Use t.Context() for the call under test, which had opted out of the
cancellation bound the setup probe in the same block already kept.

Subject: [PATCH 15/74] test: pin the inherited-veto mechanism and share the
 git transport shim
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses the review findings on this branch.

TestFetchCheckpointRefFrom_InheritedDedicatedDoesNotRetry passed on unfixed
code, and pre-fix it passed by a different mechanism than its name describes:
the lead-less ownership vote ACCEPTS the dedicated store (origin and the
checkpoint repo share an owner), so the probe failed against the store rather
than the fork. "An error that is not ErrReferenceNotFound" is true either way,
so the assertion could not tell them apart. Naming the remote in the error
discriminates in both subtests — verified by deleting the fix hunk, where it
now fails reporting acme/checkpoints.git.

The bash git transport shim existed twice, in different packages, and had
already diverged: one matched ls-remote|fetch and mapped URLs, the other
matched ls-remote|fetch|fetch-pack|push and mapped bare remote names too.
dupl cannot see it, since a heredoc is one string literal. Both now call
testutil.GitTransportShim, parameterised by the subcommand set and the rewrite
table. The table maps spellings to environment variable NAMES rather than
paths: the unit fixture repoints CHECKPOINT_TEST_UPSTREAM after the shim is
written to force a transport failure, so the indirection is load-bearing.
Entries are sorted, so the generated script does not vary with map iteration
order.

The fetchCheckpointRefFrom comment did not name the distinction it was
drawing. Both branches keep a single target; what the lead changes is how that
target is RESOLVED. It also read as though the lead becomes the fetch target,
which it does not in the common case — it joins FetchURL's ownership vote, and
becomes the target only when that vote vetoes the store as inherited.

Subject: [PATCH 16/74] fix: vote with the read candidate's push destinations
 too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fetch-side ownership vote resolved the elected remote with GetRemoteURL —
one FETCH url — while the push side votes with GetPushURLs, every push url. A
remote can fetch from one owner and push to another (remote.<name>.pushurl),
and there the two disagreed: the push vote saw {acme, contributor} and vetoed
the acme/checkpoints store, so writes went to the fork, while the fetch vote
saw {acme, acme} and accepted it, so reads came from a store that never had
them. That is the asymmetry this branch exists to close, one topology over.

The candidate's push destinations now join the vote. ADDED to its fetch url
rather than substituted for it: the rule is that EVERY identity must be owned
by the checkpoint repo's owner, so widening the set can only turn accept into
veto — no read that falls back to the candidate today can start using the
store, and the blast radius across FetchURL's other callers is bounded in one
direction. Substituting would drop an identity and could do the reverse.

A failure to resolve the push urls is an error rather than a skip, matching
the fetch url beside it: an identity whose owner cannot be determined counts
as inherited, because dropping it fails OPEN.

gitremote gains GetPushURLsInDir, the push-side counterpart of the existing
GetRemoteURLInDir. Without it the vote's two halves would describe different
repositories whenever FetchURLOptions.WorktreeRoot is set — fetch url from the
named worktree, push urls from the process working directory.

Subject: [PATCH 17/74] fix(testutil): refuse shell-injectable input to the git
 transport shim
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GitTransportShim generates a bash script by interpolating three
caller-controlled values UNQUOTED — the subcommand list and the rewrite keys
land in `case` patterns, the rewrite values land as `$NAME` — then chmods it
0755 while the caller prepends its directory to PATH. Every git invocation in
the test therefore executes it, so a key such as `x) ; curl … | sh ;;` was
arbitrary command execution.

This was self-inflicted by the previous commit. The two duplicated scripts it
replaced carried all three values as LITERALS and could not be fed anything;
sharing them is what made them feedable, and putting the result in testutil —
which carries no build tags so that every test package can import it — widened
that from two files to the repository.

Inputs are now validated fail-closed against allowlists that exclude every
shell metacharacter by construction: git subcommands, remote names and URLs,
and environment variable names. The check is a pure function so the property
is directly testable rather than only reachable through a fixture, and the
test drives thirteen vectors — pattern breaks, command substitution,
backticks, quotes, globs, newlines, brace expansion — plus the ordinary remote
names and URLs the fixtures actually pass.

The allowlists are deliberately narrower than what git accepts. A fixture
needing something outside them should write its own script rather than widen
them.

Subject: [PATCH 18/74] Revert "share the git transport shim" (keeps the review
 fixes)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reverts the shared shim helper entirely rather than keeping it hardened. It
generated a bash script by interpolating three caller-controlled values
unquoted, chmod 0755'd it, and the caller put its directory first on PATH — so
every git call in the test executed it and a rewrite key such as
`x) ; curl ... | sh ;;` was arbitrary command execution.

Validation closed that, but the helper should not have existed. The two scripts
it replaced carry all three values as LITERALS and cannot be fed anything;
sharing them is what created a path for input to reach generated shell, and
putting it in testutil — no build tags, importable by every test package —
widened that from two files to the repository. Removing it restores a state
where the property holds by construction instead of by a regex, and it was out
of scope besides: the task was to review findings, and the duplication finding
was the one recommended for deferral.

The duplication it addressed is back to being a known low: two copies of the
shim, in different packages, already differing in their matched subcommands and
whether bare remote names are mapped. dupl cannot see it, since a heredoc is
one string literal. A third copy is the point at which extraction earns its
risk — done then with a literal script per caller, not a generator.

Kept from that commit, both being fixes to real findings: the assertion naming
the remote an inherited-veto error came from, without which the test passed on
unfixed code; and the regression test for a lead whose fetch and push URLs have
different owners.

Subject: [PATCH 19/74] fix: include origin's push destinations in the
 ownership vote
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous commit added the read candidate's push urls to the fetch-side
vote but left origin exempt: fetchOwnershipURLs returned nil for it, on the
grounds that the caller already counts origin's FETCH url. Its PUSH urls were
never counted, and origin can carry a remote.origin.pushurl naming another
owner like any remote.

So the same asymmetry survived one branch over. With origin fetching from
acme/app and pushing to contributor/app, the push side voted {acme, other} and
vetoed acme/checkpoints, while the fetch side voted {acme} and accepted it —
writes to the push destination, reads from a store that never had them.

origin's push urls now join the vote, leaving only the no-candidate case
returning nil, where there is no read candidate to ask about. The resolution
is shared with the non-origin path (pushOwnershipURLs) so the two cannot
diverge again, and a failure stays an error rather than a skip: an identity
whose owner cannot be determined counts as inherited, because dropping it
fails OPEN.

Verified the new test fails with origin exempt again, where it probes
acme/checkpoints.git instead of reading origin.

Subject: [PATCH 20/74] fix: a miss on a vetoed store's target is absence, not
 a transport failure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the ownership vote vetoes a configured checkpoint_remote, the elected
remote is where the single-remote gate already routed writes — so it is the
checkpoint destination, and a missing ref on it means the ref does not exist.
It was being probed as non-authoritative, which turned that into "refusing to
treat this as absence": callers could not tell "no such checkpoint" from
"could not reach it".

fetchURLResolved now reports the veto alongside authoritative, and the
candidate-aware entry point probes a vetoed target as authoritative.

Three things this deliberately does not do.

It does not retry the legacy origin tier. The target stays single, so a stale
tip on origin can never be installed as the canonical local ref on the
strength of an elected-remote miss — which is also why this needs no
repo-level veto verdict: the earlier reading of this defect implied checking
later candidates, and there each candidate re-runs its own vote, so `origin`
re-accepts the store and the chain probes it instead.

It does not touch the lead-less FetchCheckpointRef, which must keep refusing:
its fallback may be a remote that never hosts the store's refs and it has
nothing else to consult (TestFetchCheckpointRef_FallbackTargetNeverClassifies
Absence, on main, pins this).

It does not change authoritative, which answers a different question — "is the
dedicated store what serves reads". fetchURLAuthoritative stays a thin wrapper
so FetchURL and ReadsDedicatedStore see no change; a vetoed store must not
report as serving reads.

The test becomes a two-case table, because the two now differ: a miss on the
vetoed target is absence, an unreachable one is not. Verified it
discriminates — with the change reverted the absence case fails and the
transport case still passes. It flips an assertion this branch had written, at
the reviewer's explicit direction.

Subject: [PATCH 21/74] fix: align the fetch-side ownership vote with the push
 side
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The earlier change added the read candidate's push destinations ALONGSIDE its
fetch url. That made the read vote stricter than the push vote, which is not
safer — just asymmetric in the other direction. A remote fetching from another
owner but pushing to the checkpoint owner had the push side accept the store
and route writes there, while the read side vetoed it and fell back to the
fetch repo.

The identity sets are now identical by construction: origin plus the
candidate's PUSH destinations, the same pair PushURL hands
checkpointRemoteIsInherited. The candidate's fetch url is not a voter.

This is what the original finding said to do. The additive variant was chosen
on the reasoning that widening an every-identity-must-match check can only
turn accept into veto, so it could not make reads less safe. That reasoning
answered the wrong question: the invariant is reads landing where writes went,
not maximal vetoing.

Both directions are now pinned, each verified to fail against the other
implementation: a candidate pushing away from the checkpoint owner vetoes the
store, and one pushing to it keeps the store even when its fetch url points
elsewhere.

Subject: [PATCH 22/74] fix(enable): address checkpoint destination picker
 findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Four findings from the review of the remote picker:

- Do not offer the picker when the local settings layer is rejected. The
  choice is saved to .entire/settings.local.json, so a tracked local file
  made every real answer abort `entire enable` after the user had already
  answered — and, on fresh setup, discard the agent selection.

- Treat huh.ErrUserAborted as the picker's own "Keep current destination"
  option instead of failing the command with a raw `huh: user aborted`.
  A cancelled context still aborts.

- Run the picker after the up-front flag validation, so an invocation that
  was always going to be rejected (a bad --checkpoint-backend, conflicting
  --local/--project) never opens a prompt first. The deferred destination
  report keeps its place at the top: it needs the choice pointer, not the
  answer, so it still runs last.

- Restore the multi-remote ambiguity note on every path where no picker
  ran. The gate keyed on "the prepare step ran", which is every `entire
  enable`, so non-interactive runs lost the fanout warning, the remote
  count paragraph and the checkpoint_remote pin advice.

Subject: [PATCH 23/74] fix(doctor): make the summary-provider remedy runnable
 and layer-correct

Three review findings on the new check.

The remedy printed `--summarize-provider <a|b|c>`, which a shell reads as
a redirect and a pipe, so the obvious copy-paste fails before it runs.
It now prints one runnable command and lists the alternatives on their
own line, where they are data rather than something to paste.

The remedy also omitted --local. `entire configure` with no layer flag
writes the PROJECT file whenever one exists (settingsTargetFile), so a
provider coming from settings.local.json was "fixed" in a file the local
layer still overrode: the command reported success and doctor still
reported the fault. Verified against a real repo before and after. The
diagnosis now names the file supplying the value and adds --local when
that file is the local layer.

Finally, doctor's enumerated "Checks performed" list did not mention the
check at all.

Subject: [PATCH 24/74] fix(doctor): honour the loader's local-layer verdict,
 isolate the tests

Two review findings on the layer detection added in the previous commit.

summaryProviderSourceLayer read .entire/settings.local.json directly, so
it could not see that the loader drops a TRACKED local file wholesale.
With the same provider in both files it attributed the value to the
local layer and advised --local, sending the user to edit a file the
loader ignores while the project-level fault stayed put -- the same
wrong-file advice the --local fix was meant to end. It now consults
LocalLayerRejection first, and takes the merged settings rather than a
bare string so that verdict is available to it.

The tests reached that code with the process still pointing at the
developer's own repository, so they read the real .entire/settings.local.json
and their output depended on whose machine they ran on. The isolation now
lives in the shared helper, since any test reaching the fault branch needs
it.

The layer test runs against real settings loading and the real registry:
opencode is genuinely incapable so the registry needs no stub, and the
tracked-local case cannot be stubbed at all -- localLayerRejection is
unexported, so only a real Load over a real tracked file produces it.
Verified non-vacuous by removing the guard and watching that case fail.

Subject: [PATCH 25/74] fix: install the managed plugin bin entry on Windows
 without a symlink

`entire graph` downloaded, verified and placed entire-graph.exe under
pkg/graph/ correctly, then linked a 0-byte entry into bin/ that Windows
refused to execute: "The filename, directory name, or volume label syntax
is incorrect."

Two defects in materializeManagedEntry combined. os.Root.Symlink on Windows
stores an absolute target verbatim, without the `\??\` prefix that
CreateSymbolicLinkW adds, so the link is created (Go re-enables the symlink
privilege itself, so an elevated shell gets no error) and then cannot be
followed. And os.Root.Link resolves both operands inside the root, so the
hardlink fallback, handed an absolute source, failed as a path escape on
every platform and never ran once.

Windows now skips the symlink entirely; the source is converted to a
root-relative name (managedTreeName) so the hardlink works for every remote
install, and the copy remains the fallback for local-dev sources outside the
tree. Unix keeps symlink-first. checkManagedPluginRunnable treats an
unfollowable symlink and an empty file as reinstall-fixable, so entries left
by earlier builds get the `plugin install graph --force` remedy instead of a
raw fork/exec error.

The materialize tests no longer skip on Windows and read THROUGH the entry,
which is the assertion that would have caught this; withPluginDir releases
the memoized plugin-dir root so TempDir cleanup succeeds on Windows.

   Those operations (`setupEntireDirectory`, `removeEntireDirectory`, the one
   `MkdirAll` of an agent's session dir in `resume.go`) legitimately use plain
   `os` calls.
+- **`Root.Link` takes two root-relative names, and `Root.Symlink` with an
+  absolute target is unusable on Windows.** `Root.Link(absPath, name)` fails as
+  a path escape on every platform — the plugin store's hardlink fallback did

 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)).

Windows never gets a symlink because `os.Root.Symlink` there stores an absolute target without the `\??\` prefix Windows needs to follow it, and Go re-enables the symlink privilege around the call, so an elevated shell got a 0-byte link that `exec` rejected with "The filename, directory name, or volume label syntax is incorrect" (`materializeManagedEntry` carries the details). The hardlink only applies to a source inside the managed tree — every remote install — since `os.Root.Link` takes root-relative names; a local-dev source outside the tree is copied. 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.

Subject: [PATCH 26/74] Compare carry-forward hashes with Equal, not ==
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

plumbing.Hash is a struct carrying an object-format field alongside its bytes, so == compares that field too. FromHex stamps sha256 on a 64-char hash and leaves the field unset on a 40-char one, which means == holds only while go-git's tree decoder makes the same choice. Probed against the pinned v6.0.0-alpha.5.0.20260812155443, it does — sha1 gives "" on both sides, sha256 gives "sha256" on both — so this works today by coincidence. If a decoder ever stamped "sha1", every candidate would compare dirty, the phantom carry-forward #2336 fixed would return, and nothing would fail, because no test pins the format field. Equal ignores it by construction and is already what the fallback branch three lines down uses.

Also records two decisions reviewers reached independently. hash-object takes its paths as argv rather than --stdin-paths because hash-object has no -z, so --stdin-paths is newline-delimited and splits a legal path containing a newline into two nonexistent ones; the chunking that supports argv is therefore not scaffolding to be removed. And TestGitWorktreeDiffCallSitesDoNotRefreshTheIndex drops the gitInvocationMarkers filter that TestGitStatusCallSitesPassNoOptionalLocks keeps because the failure direction inverts between them: a wrapped argv separates the flag from "status" (loud false positive) but would separate the marker from "diff" (silent false negative).

Follow-up to #2336; resolves findings on trail 1277.

Subject: [PATCH 27/74] refactor: build-tag the plugin symlink step and trim
 comments

Move the one platform difference in materializeManagedEntry into
plugin_store_unix.go / plugin_store_windows.go (the pattern
plugin_signal_{unix,windows}.go already uses) instead of a runtime.GOOS
branch, and cut the comments down to what a reader needs.

 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 binary lands in `pkg/<name>/` next to a `manifest.yml` — written atomically, and *before* the `bin/` link — recording provenance (repo URL, tag, asset, asset SHA-256, **binary SHA-256**, verification state, pin state, dependency list), and is linked into `bin/` through the same fallback ladder as local installs: symlink → hardlink → copy on Unix, hardlink → copy on Windows. Windows never gets a symlink because `os.Root.Symlink` there stores an absolute target without the `\??\` prefix Windows needs to follow it, and Go re-enables the symlink privilege around the call, so an elevated shell got a 0-byte link that `exec` rejected with "The filename, directory name, or volume label syntax is incorrect" (`materializeManagedEntry` carries the details). The hardlink only applies to a source inside the managed tree — every remote install — since `os.Root.Link` takes root-relative names; a local-dev source outside the tree is copied. The dispatcher never changes.

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.

Subject: [PATCH 28/74] Use Equal for every plumbing.Hash comparison, and guard
 it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The first commit changed only the call site the original finding named and left seven others, one of them 45 lines above it in the same function — so a comment explaining why == is wrong sat just below a == doing the same thing. All eight now use Equal.

Adds a source guard rather than a test, because no test can distinguish the two operators. Checked against the pinned go-git: NewHash, FromHex, ResetBySize and Hasher.Sum all leave the object-format field unset for a 40-char hash and stamp "sha256" only on a 64-char one, so two hashes of the same object in one repository always carry the same format and == cannot disagree with Equal. The mismatch is unconstructible through the public API, which means a reverted call site stays green no matter what is asserted. TestHashComparisonsUseEqual pins the convention where it is written instead, and was verified by reverting content_overlap.go:497 and watching it fail.

That also answers the review note on the previous commit: the autocrlf regression does not pin this, and cannot. It passes with either operator.

Follow-up to #2336; resolves findings on trails 1277 and 1305.

Subject: [PATCH 29/74] Catch hash comparisons on either side of the operator
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The guard added in the previous commit matched only a .Hash on the left of == or !=, so `stagedHash == shadowFile.Hash` in content_overlap.go:285 walked past it — in the file the guard was written for. Its doc comment claimed the left-hand shape was every occurrence in the repository. It was not: widening the pattern turned up five more in strategy/, four of them comparing Reference.Hash(), a method returning plumbing.Hash rather than a field. Fourteen sites total, not eight.

The pattern now covers a .Hash field or a .Hash() call on either side, and was verified by reverting one of each newly-covered shape and watching the guard fail.

Also records why the pattern may not be tightened with \b or \s: git grep -E is POSIX ERE and supports neither, so such a pattern matches nothing and the guard reports a clean tree. `\.Hash\b` finds 0 lines in a file where `\.Hash` finds 20, which is how the missed right-hand shape was nearly confirmed as absent.

Follow-up to #2336; resolves findings on trails 1277 and 1305.

Subject: [PATCH 30/74] Report each agent's smoke verdict on its own step

The six "Smoke test <agent>" bodies run under `set +e` so the result row is
written before the step ends, but nothing propagated the captured exit code,
so a step's status was that of its trailing `echo`: every agent step showed
green and only Summarize turned red. In run 34583415795 copilot-cli failed on
Windows behind a green step.

`set +e` predates the split into per-agent steps. Those are gated on
`!cancelled()`, which already keeps the later agents running after a failed
one, so ending each body with `exit "$rc"` puts the verdict where the reader
looks while Summarize keeps the aggregate table.

Subject: [PATCH 31/74] fix: address review findings on the Windows plugin bin
 entry

- Name the Windows-relevant tests with "Windows" so CI's test-windows job
  (-run '(Windows|MSYS)') runs the materialize, managedTreeName,
  unfollowable-symlink and bin-entry hash assertions; split the last two
  into their own tests.
- plugin doctor now reports every bin/ entry checkManagedPluginRunnable
  refuses and names the same remedy the on-demand path does
  (entire plugin install <name> --force), and its integrity check also
  hashes a non-symlink bin/ entry against binary_sha256.
- Drop the redundant fs.ValidPath after filepath.Rel+IsLocal, name the
  runnable-case type once, and fix stale symlink wording in
  InstallPluginFromPath's doc comment and external-commands.md.

 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:

TestRunPluginDoctor_ChecksBinEntry drives the two doctor branches added for

and a non-symlink bin/ entry whose bytes drifted from an intact pkg/.

Subject: [PATCH 33/74] fix: second-pass review findings on the plugin bin
 entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Dispatch checks a managed entry before exec: LookPath accepts a 0-byte
  executable, so an empty bin/ entry used to fail with "exec format error"
  instead of the reinstall remedy the on-demand path prints.
- Doctor's integrity check settles the bin/ entry with os.SameFile first
  (hardlink or symlink to pkg/: no second read), hashes only a genuinely
  separate file, and reports a differing one as "not the installed release
  binary" — a local `plugin install <path> --force` over a release produces
  that shape deliberately, so the remedy says to keep it if intended.
- Doctor names the link target again for an unrunnable symlink entry.
- The Windows unfollowable-symlink test fails rather than skips on CI when
  the runner cannot create the link.

Subject: [PATCH 34/74] git-remote-entire: delete the wrong-cluster hint, which
 cannot fire
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fatalMessage special-cased an RFC 8693 invalid_target error whose
description named the cluster actually serving the repo, turning it into
"this repository is not hosted on X; it lives on Y" plus a corrected
clone command. Nothing can produce that error any more, so the branch has
never been reachable in main.

It was added in #1575 (2026-06-30), built on the repo-scoped token
exchange the helper performed at the time. #1621 removed that exchange
for the interactive path — merged 2026-07-03 05:17, six hours BEFORE
#1575 merged at 11:22 — and #1622 migrated the ENTIRE_TOKEN path the next
morning. Both PRs were the same author's; neither conflicted with #1575
in any file, so nothing flagged it. The helper now presents a
jurisdiction token as a bearer and never exchanges, so no invalid_target
is ever returned to it.

Measured rather than reasoned. Cloning a single-placement repo from the
wrong cluster, against a helper built from main:

    $ git clone entire://aws-eu-central-1.entire.io/gh/entireio/cli-perf-benchmarks
    fatal: stateless-connect v2 info/refs: Repository not found

with ENTIRE_DEBUG showing the wire:

    GET /gh/entireio/cli-perf-benchmarks/info/refs?service=git-upload-pack
    HTTP/1.1 404 Not Found
    Repository not found

A plain 404 with a four-word body: no invalid_target, no
error_description, nothing naming the correct host. The same repo on its
own cluster clones fine with the same credentials, so that 404 is the
wrong-cluster response rather than an access failure.

So this is not repairable here. The 404 carries no information about
where the repo lives, and no client-side matcher can invent it. Restoring
the UX needs the data plane to say so on that response — worth noting the
helper already looks for an X-Entire-Replicas header there and logs its
absence, so the mechanism may partly exist. Filed separately; this commit
only removes code that cannot run.

TestFatalMessage went with it. It passed throughout by constructing the
invalid_target error itself, which verified the formatting and could
never observe that the input had no producer — the reason a dead branch
survived two years of green CI.

fatalMessage reduced to a single Sprintf with one caller, so it is
inlined rather than kept as a seam. If the hint returns it will match a
404 body, not an OAuth error, and would not reuse this shape.

Subject: [PATCH 35/74] fix: a local plugin override is a doctor note, not a
 fault

The bin/ entry report added for a local `plugin install <path> --force`
over a release made `plugin doctor` exit 1 for a state whose remedy is
"keep it". PluginDoctorIssue gains Note; the command prints notes with a
`note:` prefix, counts only faults for its exit status, and still says
"All plugins healthy." when notes are all it found.

 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:

Subject: [PATCH 36/74] fix(doctor): suggest a summary provider that is
 actually installed

The Fix command was built from summaryCapableProviderNames()[0], which
is deliberately unfiltered by $PATH -- correct for "what does this field
accept", wrong for a command to run. Being alphabetical it said
claude-code on a machine with no claude, and `configure` then rejected
it on its own PATH check. The user this check fires for is the likeliest
to have exactly one agent installed, and by construction it is not one
that can generate text.

It now names the first INSTALLED capable provider. When none is
installed no command is printed at all -- a command that cannot work is
worse than none -- and the Supported line says why.

Verified end to end against a stripped PATH (no Fix line, with the
reason) and a codex-only PATH (suggests codex, not claude-code). The
tests pin the availability seam as well as the registry, since the Fix
line would otherwise depend on which agents the developer has installed.

Subject: [PATCH 37/74] fix: read a vetoed store's refs from the push
 destination, and keep origin uncertain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three findings, all on the vetoed branch.

The fetch TARGET was resolved from the candidate's fetch url while writes go to
its push destination, so with remote.<name>.pushurl pointing elsewhere reads
queried the wrong repository — a stale ref, or a false absence. It now takes
the first push url, matching the push side's own transport derivation and the
single destination checkpoint refs are sent to.

vetoed was reported true on BOTH returns of that branch, including the one
where the candidate could not be resolved and the url fell back to origin. That
path is reached BECAUSE the candidate was unusable, so writes never went there
and its emptiness proves nothing — yet `authoritative || vetoed` classified it
as global absence, the exact case the comment this replaced existed to guard.
fetchURLFromReadCandidates already computes the distinction and it was being
discarded; it now carries the flag, which also comes out right for
lead == "origin", where origin IS the elected remote.

The tests could not have caught the first of these: the fixture seeds both
repositories so an assertion on one hash holds whichever spelling is probed, so
they pinned the ownership VOTE and nothing about the target. Both veto tests
now use two repositories at different hashes and assert the push destination's.

Also adds the test the second fix lacked. Reverting it left the suite green,
which is how it would have regressed silently; it uses the reported repro (the
candidate removed after the election) and fails without the fix. Each of the
three is now verified to fail against the implementation it replaced.

Subject: [PATCH 38/74] fix: resolve push URLs with git's repo-selector
 variables removed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GetPushURLsInDir names its target with cmd.Dir, and git exports GIT_DIR and
GIT_WORK_TREE to the hooks it runs, where they outrank cmd.Dir. Called from a
hook the child therefore reported the HOOK's remotes rather than the
directory's — and this output feeds the checkpoint ownership vote, so the wrong
repository's URLs would decide where checkpoints are read from.

The environment is filtered by the caller rather than inside gitremote, which
depends on nothing beyond the standard library while gitrepo pulls in go-git;
checkpoint/remote already imports gitrepo. Its sibling GetRemoteURLInDir has
the same gap and many more callers, so it is left alone here.

Also annotates the two near-identical transport shims with each other's
location, how they intentionally differ, and why they stay literal: they were
shared once, as a helper that built the script by interpolating its subcommand
set and rewrite table, which turned two literals into a shell-code generator
whose inputs reached an executable placed first on PATH. The duplication
finding is about divergence going unnoticed, and a cross-reference addresses
that without a generator. Dedupe by giving each caller its own literal script,
never by generating one from parameters.

Subject: [PATCH 39/74] refactor(enable): only prompt for the checkpoint remote
 on first setup

Follow-ups from the review notes on #1286, none of them defects:

- The picker now opens only during interactive first-time setup. A bare
  re-enable in a configured repo never prompts: "Keep current destination"
  writes nothing, so the picker came back on every run with no way to say
  "stop asking" short of pinning a remote. Changing the destination later,
  or repairing a saved remote that no longer exists, is
  --checkpoint-push-remote.

- The closing destination report is printed only when the destination was
  touched (explicit flag, picker shown, --checkpoint-remote) or is
  unusable. A healthy destination nobody asked about ends at "Ready."
  instead of three trailing lines, and "No checkpoint destination settings
  changed." appears only when a change was asked for and was a no-op.

- The picker description counts the remotes it actually offers rather
  than every destination in the topology.

- Drop the unreachable second "cannot be combined" check, load settings
  only on the explicit path that reads them, and make
  validateCheckpointPushRemote one subprocess: `git remote get-url` is
  exactly the check that cannot see a pushurl-only remote, and an unset
  remote.<name>.url already covers an unknown remote.

From 63e829f689e35a4ad4355356696cbfe4fa1df09d Mon Sep 17 00:00:00 2001
From: Peyton Montei <peyton@entire.io>
Date: Fri, 11 Sep 2026 11:22:54 -0700
Subject: [PATCH 40/74] fix: take the vetoed target from the URLs the vote
 already resolved
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The push destinations were re-resolved with a second `git remote get-url
--push --all`, for a value the ownership vote had just produced and left in
scope. Two of the six subprocesses on that path were the same command run
twice.

The subprocess is the smaller half. "Reads land where writes went" is decided
by the vote, so the target should BE the voted value rather than a second read
of the same config that could in principle disagree with it. ownershipURLs is
non-empty exactly when checkpointRemoteIsInherited was consulted, since an
ownership error is treated as inherited without one — so the guard tracks the
condition rather than approximating it.

Corrects the previous commit's message, which asserted a bug I did not verify
was reachable:

  "Called from a hook the child therefore reported the HOOK's remotes
   rather than the directory's"

It cannot, through any current caller. All three derive their root from
paths.WorktreeRoot, which itself honours GIT_DIR/GIT_WORK_TREE — the
documented reason gitrepo.OpenCurrent must not fall back to "." — so under a
hook it already resolves to the hook's repository, the same one those
variables would have forced. The two agree, before and after.

The filtering stays, as hygiene rather than a fix: cmd.Dir is correct today
only because it agrees with what would override it, and this removes the
dependence. The reasoning now lives in GetPushURLsInDir's doc comment, where
it outlasts a commit message, together with the asymmetry it leaves behind —
one ownership vote now reaches git through two mechanisms, harmless while both
resolve to the same repository, but GetRemoteURLInDir should be given the same
treatment in the same change rather than leaving the vote split.

Subject: [PATCH 41/74] fix: close the two residual misroutes the risk
 rationale names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The risk monitor's worst case for this branch is "a misrouted read or stale
local checkpoint ref". Two paths still fed it, both documented rather than
fixed, which is the wrong way round.

An unresolvable candidate fell through to its FETCH url. When the ownership
vote could not resolve a NAMED candidate's push destinations it produced no
URLs, and the target then came from the candidate's fetch url — the misroute
this series exists to prevent. It now fails closed, matching how the vote
already treats an identity whose owner cannot be determined: as inherited
rather than dropped, because dropping it fails OPEN. Named is the operative
word; with no candidate there is nothing to resolve and origin is the target
by default, which is the ordinary path rather than a failure.

One ownership vote reached git two ways. The candidate half filtered git's
repo-selector variables and the origin half did not, so the two halves of a
single decision could in principle describe different repositories. Both now
use the same form. Scoped to the vote through an internal wrapper: the
exported GetRemoteURLInDir keeps its behaviour, because its other callers are
user-invoked commands acting on the current directory, where a GIT_DIR the
user exported is an instruction and not contamination.

Also trims GetPushURLsInDir's doc, which had grown to 27 lines for a 20-line
function and taught a generic git helper what a "checkpoint ownership vote"
is. The domain half moved to pushOwnershipURLs, which owns that invariant.

Subject: [PATCH 42/74] fix: filter the vote's environment exactly when a
 directory is named
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous commit closed one asymmetry by opening another. It filtered the
candidate half unconditionally while the origin half is filtered only when
opt.WorktreeRoot is set — and every production caller but one leaves that
empty. Inside a hook the origin half then resolves through GIT_DIR while the
push half, having stripped it, resolves from the process working directory:
one vote, two identities, two repositories. The doc comment asserting "both
reach git the same way" was false as written.

Filtering both unconditionally would break the other direction. With no
directory named, nothing else identifies the repository — the ambient
environment IS the target, so stripping GIT_DIR silently retargets the child
at the working directory, which inside a hook is a different repo again. The
rule is to filter exactly when cmd.Dir names the target, so it decides rather
than being outranked.

That rule now lives in one function both halves call, because they have
diverged twice: first as unfiltered versus filtered, then as conditional
versus unconditional. EnvWithoutRepoOverrides appears once in the file, so
diverging again means deleting a shared call rather than forgetting to mirror
an edit.

Subject: [PATCH 43/74] Accept /et/<project>/<repo> paths in every repo-ref
 command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The API returns a repo's identity as a path ("/et/<project>/<repo>") and
`repo clone` accepts it, but every other repo-ref command (get, delete,
visibility, protection, grant repo) rejected it as "a name", breaking the
read-a-repo-copy-its-path loop (COR-1632).

All those commands already share resolveRepoRef, so teach it the path
grammar there: a slash-bearing ref is dispatched to the native parser
(reusing parseNativeCloneRef, so leading-slash tolerance, .git trimming,
and server-shape validation come along) and never sent to the by-name
lookup, which cannot match a slash anyway.

The #2252 rule — every ref names its forge — holds at the resolver: a
bare <a>/<b> is refused with a /et/ suggestion rather than read as
native, and a /gh/ mirror ref gets a targeted refusal pointing at
`entire repo mirror` instead of the misleading "is a name" error.

--project alongside a path ref is checked for agreement rather than
trusted or ignored: a name compares case-insensitively (the server
matches lower(name); project names are globally unique), a ULID against
the resolved project id — neither costs an extra round trip. A mismatch
is an error naming both values, since the callers include delete.

Subject: [PATCH 44/74] Dispatch path refs on the ref as given, not
 slash-trimmed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The slash-bearing dispatch checked trimRefPrefix's output, so a ref like
"/web" (leading slash, one segment) fell through to the by-name lookup
with the slash still in it — a guaranteed server 404, since repo names
can never contain '/'. Check the ref as given so every slash-bearing ref
is refused locally, as the resolver's doc comment already claimed.

Found by Copilot review on #2387.

Subject: [PATCH 45/74] fix(status): pin the aligned ownership vote in the
 push-disabled test

TestRunStatus_CheckpointPushDisabledDestinations has failed on main since
#2342 merged over #2337. #2337 added a row asserting that the read-side
ownership vote counts the candidate's FETCH url while the push side counts
its PUSH urls, so a remote fetching from another owner but pushing to the
checkpoint owner was accepted by writes and rejected by reads. #2342
deliberately aligned the two votes on origin plus the candidate's push
urls, so that row now sees the dedicated store as the read source.

Replace the row with two that pin the aligned semantics in both directions:
a candidate pushing to the store's owner is accepted whatever its fetch
url names, and one pushing elsewhere is rejected and reported as not in
use. Update the status.go comments that still described the asymmetric
vote; the read-side "not in use" branch stays, because ReadsDedicatedStore
can still decline for non-ownership reasons the push verdict never sees.

Two comments still described the read side as voting on the candidate's
fetch url: the resolveDedicatedReadSource doc, and the accepted-divergence
note above the "not in use" branch. The divergence that note records is
real but narrower than it said — only a fetch with NO read candidate votes
on origin alone — so say exactly that.

Subject: [PATCH 47/74] Say what --project does, and what a mirror ref does not
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-ups to #2387, which took the native /et/<project>/<repo> path into
resolveRepoRef and so into every command that resolves a repo ref.

--project was left in an indefensible middle. It serves the bare-name
spelling alone: a repo name is unique only within a project, and the control
plane has no by-name route that is not project-scoped, so without the flag a
bare name is not an address. The other two spellings carry their own project,
and the two disagreed about saying so. A path ref is checked for agreement,
which is free because the resolver looks that project up anyway; a ULID
short-circuits before projectRef is ever read, so a flatly wrong project was
accepted in silence. Warn on the ULID rather than validating it — validation
needs GetRepo's owningProjectId, an extra round trip on every command here
but `repo get` — and warn rather than refuse, because the combination has
been accepted since the flag shipped in June and is plausibly scripted.
The hook rides on bindRepoProjectFlag, so it cannot be wired for some of the
ten commands and missed for others.

The /gh/ refusal claimed "this command addresses Entire-native repos", which
is false: several commands sharing this resolver address mirror repos by
ULID, and `repo protection list` answers one with protectionMirrorNote —
branch protection is governed upstream — which is a better answer than the
refusal gave. `entire repo mirror`, where it sent them, has no protection or
visibility counterpart. What genuinely cannot work is the by-name lookup: it
resolves a project and then a repo inside it, and a mirror is in no project.
So the message now describes the ref shape and names the ULID as the way
through.

The rest is text that went stale in the same change: `grant repo add` and
`grant repo remove` still told the user a repo is addressed "by name or
ULID", and CLAUDE.md still framed the native path as clone-only when it is
now accepted by ten commands — while the other two clone shapes are not.

TestCloneRefAlwaysRequiresItsForgePrefix follows the requirement rather than
the command, so its table now runs against resolveRepoRef too, with and
without --project. The invariant already held; nothing pinned it there.

Subject: [PATCH 48/74] checkpoint: accept case-folded shard directories in
 ParseRef

On a case-insensitive-but-case-preserving filesystem (macOS APFS, Windows
NTFS defaults), git resolves a new checkpoint ref's shard directory against
existing ones case-insensitively. A ULID checkpoint's canonical shard is
uppercase (e.g. "6B"), so if an unrelated legacy hex checkpoint already
shards to the lowercase form ("6b"), the new ref lands inside that same
lowercase directory instead of a distinct one.

ParseRef then rejected such refs outright: it recomputed the ID's shard and
required an exact, case-sensitive match against the ref's actual path
component, so "6B" != "6b" caused a well-formed, intact checkpoint to be
treated as malformed and silently disappear from `entire checkpoint list`/
`explain`.

Fix: compare the shard case-insensitively (strings.EqualFold) instead of
exactly. Adds regression tests reproducing both directions of the collision.

Fixes #2402

Subject: [PATCH 50/74] docs: install Homebrew casks by fully qualified name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`brew tap entireio/tap` fails outright under Homebrew 6's tap trust: tapping
runs a readall audit over every cask in the tap, each load hits the trust check,
and the tap is left empty behind `Cannot tap entireio/tap: invalid syntax in
tap!`. The README told users to run it first, so the documented install died on
step one (#2394).

A fully qualified `<tap>/<token>` is exempt from that check, and `brew install`
auto-taps without the audit (`Tap#install` defaults to `verify: false`; only
`cmd/tap.rb` passes `verify: true`), then persists scoped trust for the one cask
it installed. So the whole flow collapses to a single command, with `brew
upgrade` still working by short name afterwards.

This is what #1427 proposed. It was held back because `conflicts_with` then
forced you to trust both casks before either would install; Homebrew fixed that
in 6.0.10 (Homebrew/brew#23027) by rescuing UntrustedTapError in
`check_conflicts`. The other two mechanisms predate tap trust entirely, so
6.0.10 is the floor.

Also add a stable-install job to the nightly smoke workflow. The macOS leg only
ever installed the nightly cask, and the old sequence there ran `brew trust`
before `brew tap` — the working order — so CI stayed green while the README was
broken. A runner starts with no tap and no trust entries, which is the state
that reproduces it.

Subject: [PATCH 51/74] ci: drop "Nightly" from the install-smoke Slack heading

The heading was unambiguous while the workflow tested one channel: the
schedule, the workflow and the release channel were all "nightly". Covering
stable split those, so a stable-only failure alerted "Nightly install smoke
failed" while the nightly job had passed.

The body already reads "a published CLI ... at least one channel/OS", so the
heading was the only part asserting a channel. Naming the failing job instead
would need three nested ternaries inside the JSON payload to cover both-failed;
the run link already carries it.

Subject: [PATCH 52/74] e2e: add control-plane suite with device-flow login and
 repo lifecycle test

Add e2e/controlplane, a package that drives 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 through playwright-go, so every
test starts from that session.

TestControlPlane_CreateCloneDelete creates an org, a project in it, and a
repo in that project, waits until the read path reports the repo clonable,
clones it, checks both `git remote -v` lines, and deletes repo, project,
and org in that order.

`mise run test:e2e:controlplane` builds the binaries, installs the
Playwright driver and Chromium, and runs the package; the new
e2e-controlplane.yml workflow runs it on manual dispatch and pushes to
main using the E2E_GH_USERNAME and E2E_GH_PASSWORD secrets.

 XDG_CACHE_HOME

On Linux Playwright resolves its browser directory from XDG_CACHE_HOME,
which TestMain redirects to an isolated temp dir for the CLI, so Chromium
installed by the mise task was not found. Pin PLAYWRIGHT_BROWSERS_PATH to
the real user cache first.

Subject: [PATCH 57/74] e2e: answer GitHub's authenticator prompt during the
 device login

Signing in from a fresh CI runner hits GitHub's new-device verification,
which emails a code and cannot be automated. GitHub skips it for accounts
with 2FA enabled, so the test account uses an authenticator app and the
browser step now fills the RFC 6238 code computed from E2E_GH_TOTP_SECRET,
required alongside the username and password.

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`; every test then starts from that session. The CLI's config and token store live in a temp dir outside `e2e/artifacts/`, which CI uploads.
+`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 dies before cleanup needs its leftovers removed by hand.

Subject: [PATCH 60/74] fix: give the dispatcher the same entry repair as
 plugin doctor

managedEntryUnrunnable printed a bare `entire plugin install <name>
--force` for every repairable bin/ entry, while doctor had moved to
entryRepairFix: the recorded URL with --pin/--allow-unverified for a
release install, rebuild-or-remove for a manifest-less local-dev entry.
The dispatcher now reuses the helper, so `entire graph` failing on a
broken entry prints the repair doctor would, and the two cannot drift.

Also from the review of 69136b41f: the non-executable-link problem text
drops "dangling or" (a dangling link is caught by the stat first), the
unreadable-manifest branch of entryRepairFix gains a test, and the
stale duplicate comment on the stat guard in checkManagedBinaryIntegrity
is removed. external-commands.md describes the manifest-aware repair.

Findings: 01M2GASRMQ, 01M2GASV6G, 01M2GASZN7, 01M2GAT1MT.

Subject: [PATCH 61/74] fix identity check for native cross-repo explain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

entire-api's repo_full_name is the bare pair for both forges — Core builds
a native repo's full name as project/repo, never et/-prefixed — so the
et/-qualified comparand made verifyResponseIdentity reject every native
--repo read. newAPICheckpointReader now derives both the forge-qualified
display ref and the bare identity comparand from one (forge, owner, repo)
triple, so a caller cannot pair them inconsistently again.

Subject: [PATCH 62/74] e2e(controlplane): revoke the session, tolerate read
 lag, name stalled pages

TestMain logs out after the run so the shared test account does not
accumulate a live login per CI run. The clonable poll treats a by-name
not-found from `repo get` as not ready yet instead of failing the test.
The browser stepper reports the page a login is stuck on after a minute
without navigation rather than waiting for the context deadline. The
TOTP key is decoded unpadded as GitHub displays it, and the task
description names the TOTP secret it requires.

Each call to runEntireWithTimeout creates its own context, so cleanup
getting a fresh deadline holds by construction, and the fixture never
spawned the descendant that WaitDelay exists for. It also ran only after
a production login and pinned the package to a single binary override.

switch to the ULID once decoded, since an already-deleted ULID exits 0

Subject: [PATCH 69/74] e2e(controlplane): sweep orgs left behind by runs that
 ended without cleanup

t.Cleanup cannot run when the process is killed: a package timeout, a
cancelled job, or a lost runner. With a three-org quota on the test
account, one such run blocked every later one until someone deleted the
leftovers by hand. Each run now starts by deleting e2e-cp-* orgs older
than 30 minutes, with their projects and repos; the age gate leaves a
run in progress elsewhere alone.

 `controlplane/` runs the `entire` binary against the production control plane with no coding agent involved.

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.

Subject: [PATCH 70/74] fix: release the pending console read before closing a
 prompt terminal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On Windows, answering a plugin confirmation needed a second keypress
before the confirmed action started. Bubble Tea only builds a
cancellable console reader for os.Stdin; the separately opened CONIN$
handle the prompt uses gets a fallback whose Cancel is a no-op, so the
read its loop issued after the answer stays pending, and Go's
os.File.Close on Windows waits for every pending operation — which a
console completes only on a keypress.

PromptTTY.Close now cancels pending I/O on the input (CancelIoEx) before
closing it, and the plugin confirmation opens its terminal through
interactive.OpenPromptTTY instead of tea.OpenTTY so it goes through that
Close. The login key prompt already did, so it is fixed by the same
change. The cancelled read reports io.EOF, so the close stays after the
form has returned.

Verified on Windows 11 (conhost) with a minimal program: Close blocked
until a key was injected before, returns immediately after.

 `interactive.UnderTest()` returns true when `testing.Testing()` or `ENTIRE_TEST_TTY` is set — use it where code needs to skip a real-terminal operation even if `CanPromptInteractively()` returns true (e.g., opening `interactive.OpenPromptTTY()` directly inside a prompt reader).
 
+A prompt that runs Bubble Tea on a separately opened terminal (plugin confirmations, the login key prompt) must open it with `interactive.OpenPromptTTY()` and release it with `PromptTTY.Close()`, never `tea.OpenTTY()` plus a bare `Close`. Bubble Tea only gets a cancellable console reader for `os.Stdin`; on any other handle its reader loop leaves a read pending after the answer, and Go's `os.File.Close` on Windows waits for that read, which a console completes only on a keypress — the user had to press Enter twice. `PromptTTY.Close` cancels the pending read first (`CancelIoEx`, `tty_release_windows.go`); the reader then sees `io.EOF`, so the close must come after the form has returned.

Subject: [PATCH 71/74] fix(lifecycle): compare committed files through Git's
 clean filters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

filterToUncommittedFiles decided "already committed" by comparing the
working tree's raw bytes against the HEAD blob. Under core.autocrlf —
the Git for Windows default, and what both testutil.InitRepo and
e2e/testutil/repo.go set — the working tree holds CRLF while the blob
holds LF, so every committed text file compared unequal and the filter
never dropped anything.

That matters because the filter is what stops an agent's mid-turn commit
from being checkpointed twice. With it broken, turn-end saw a file that
PostCommit had already condensed, missed the "no changes, skip" gate, and
minted a fresh shadow branch on the *new* HEAD seconds after PostCommit
deleted the old one. Nothing condenses that branch away — the session
ends and no further commit arrives — so it outlives the session. On the
nightly install smoke that surfaced as copilot-cli failing
TestMultiSessionSequential on windows-latest with "shadow branches should
be cleaned up within 10s after commit", every night since 09-11.

The condition was latent from the start and only became reachable when
copilot-cli's turn-end file list stopped being empty. The last green
nightly ran the same broken filter, so its list was genuinely empty
rather than correctly filtered; the only extraction change in that window
is #2341's restrictedProperties.filePaths fallback. That fallback follows
Copilot moving the field out of properties, so both halves are needed to
explain the flip — and neither is at fault: reporting a path the agent
later committed is correct at that layer, and narrowing it to what is
still uncommitted is this function's job. The three other Windows agents
produce no turn-end list at all and so never reached the comparison.

Compare through gitrepo.HashWorktreeFiles (git hash-object) instead, which
applies Git's path-specific clean filters. This also fixes .gitattributes
eol/text rules and clean filters such as Git LFS, which the byte
comparison got wrong for the same reason. Symlinks stay on the raw path:
hash-object follows the link and hashes the target's content, while a Git
symlink blob stores the target path. Anything Git cannot hash falls back
to the previous comparison, so the function still fails open — toward
keeping a file rather than dropping one.

Both call sites benefit: turn-end and the subagent task path, whose own
comment already described this exact failure.

Subject: [PATCH 72/74] fix(lifecycle): withhold non-regular worktree entries
 from hash-object
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Checking only the HEAD entry's mode was not enough. git hash-object
follows a working-tree symlink and hashes the target's *content*, so a
tracked regular file replaced by a link to identical content hashes equal
to its HEAD blob and was dropped as "already committed" — while git status
calls it a typechange (" T"). The HEAD entry is still a regular file, so
the tree mode cannot catch it. Verified directly: after replacing a
committed foo.txt with a symlink to a file of equal content,
`git hash-object -- foo.txt` returns the HEAD blob hash exactly.

That drops a real change, which is the direction this function must never
fail in. A FIFO is worse than wrong: hash-object blocks reading it, and on
a hook path that costs the caller its whole budget.

strategy already had this rule and a test asserting it, so rather than add
a third copy the pair moves to worktreedir.HashableEntry, where both
callers reach it. It cannot live beside HashWorktreeFiles in gitrepo:
worktreedir's own test imports testutil, which imports gitrepo, so that
edge is an import cycle in the test binary. Its tests move with it, and
content_overlap_test keeps the half that is still its own — what the
confined fallback answers for a symlink.

Reported by Cursor Bugbot and Copilot on #2482, both pointing at
strategy.requiresConfinedWorktreeHash as the precedent. They were right.

Subject: [PATCH 73/74] fix: close the prompt terminal even when releasing its
 pending read fails

PromptTTY.Close returned before closing either console handle when
CancelIoEx failed with anything but ERROR_NOT_FOUND, and every caller
discards Close's error, so both handles leaked silently. The release
failure is now joined with the close errors instead of replacing them.

The Windows regression test also asserts that the released read reports
io.EOF. Without that, a Close that ran before the read was pending still
passed: CancelIoEx found nothing, the read then hit a closed handle, and
both selects succeeded.

Subject: [PATCH 74/74] e2e(controlplane): address the trail review findings

The sweep of leftover orgs is now best effort: a leftover it cannot list
or delete is logged and skipped instead of failing the current run, and
"swept" is logged only once the org delete succeeded. The device login
runs in the isolated state dir rather than the checkout, a stalled
about:blank page is named instead of printed as an empty host, and the
sweep no longer reuses one output variable across nested listings.

Restores the offline RFC 6238 vector test, now also covering a padded
key: the production workflow runs only on main and manual dispatch, so
this is the only check of the algorithm that runs on every PR.
