Summary

  • What changed?

    The plugin now knows which build of itself OpenCode loaded, and says so.

    On startup it resolves its own package root from import.meta.url, reads the
    name and version there, and classifies the root as an installed package or
    a working checkout. That origin is appended to
    ~/.opencode/oc-codex-multi-auth-origin.json, which keeps a short history of
    every origin the plugin has run from rather than only the latest one.

    Three behaviours follow from it:

    • The daily update check is skipped entirely for a build loaded from a
      checkout. No npm request, no toast, no scheduled cache eviction.
    • codex-status and codex-doctor report the running build, and
      codex-doctor raises a warning when the plugin used to run from a checkout
      and now runs from the installed package.
    • The installer prints the path of a checkout the plugin has run from when the
      finished config does not register it.
  • Why is this needed?

    Developing on this project means pointing OpenCode at a clone, and nothing in
    the plugin could tell that apart from a normal install. Two things went wrong
    as a result.

    A contributor running their own build was told daily that a newer version was
    on npm and offered to have the cached copy refreshed on restart. Neither
    statement applies to a checkout: the published version says nothing about
    local edits, and evicting the package cache would not change what loads. The
    prompt was noise, and acting on it meant running the installer, which until
    recently replaced the checkout entry outright.

    And when a checkout did stop being loaded, nothing said so. The plugin kept
    working, so the only symptom was edits silently no longer taking effect -
    which reads as "my change didn't work", not "I am running a different build".
    This is the piece that makes such a switch visible instead of leaving it to be
    noticed weeks later.

    The history is append-only for that reason. A marker holding just the latest
    origin would be overwritten by the very event worth reporting, and would then
    confirm the replaced state rather than flag it.

Testing

  • npm run lint
  • npm run build
  • npm test

npm test reports 3589 passed, 1 skipped, 2 failed. Both failures are in
test/index-retry.test.ts and are pre-existing on this PR's base branch under
full-suite load: the same two fail there with none of this PR's changes applied,
and all 6 tests in that file pass when the file is run on its own on either
branch. This PR adds 24 tests, all passing.

Beyond the suite, the built installer was run against sandbox homes to confirm
the end-to-end behaviour: a config that no longer registers a recorded checkout
gets the notice naming that path and is left unmodified, and a config that does
register the checkout gets no notice and is likewise left unmodified.

Compliance Confirmation

  • This change stays within the repository scope and OpenAI Terms of Service expectations.
  • This change uses official authentication flows only and does not add bypass, scraping, or credential-sharing behavior.
  • I updated tests and documentation when the change affected users, maintainers, or repository behavior.

Notes

  • Linked issue:

  • Follow-up work or rollout notes:

    This PR depends on acceptance of fix(installer): keep a local checkout registered instead of replacing it #259, the installer fix it is
    branched from (fix/preserve-local-checkout-plugin-entries). It builds on that branch
    directly, so once that one merges, its commits leave this diff and what
    remains is only the origin work described above.

    If that PR is accepted as-is, this one can be merged straight after it. If it
    is accepted with changes, I will rebase this branch onto the merged result and
    update this PR.

    The origin record contains a package name, a version, and a filesystem path.
    It holds no account, token, or request data. It is written once per process
    start, and never under a test runner.

This PR is AI generated, but under direct supervision and on request of @Nowaker.

Summary

the pr identifies whether opencode loaded an installed package or local checkout and records a bounded origin history.

  • local checkouts skip update checks and cache eviction.
  • status and doctor output report the running origin and warn about replaced checkouts.
  • the installer preserves checkout registrations and reports previously used checkouts.
  • cache deletion gains containment checks, including protection against symlinks targeting working directories.
  • origin-history writes use a lease and windows-aware atomic replacement. no token data is added to the history or diagnostics.

A config that points OpenCode at a working clone of this repository lost
that entry on the next install. Any path ending in `/oc-codex-multi-auth`
was read as an installer-written reference, removed, and replaced with the
published package name, so the next request ran against npm rather than
the code being edited - silently, with the previous entry recoverable only
from the backup file.

Renaming the clone did not help. A differently named directory survived the
filter, but the published name was still appended beside it, leaving both
copies registered at once. No directory name produced a correct result.

Entries are now identified by the package they resolve to, read from the
nearest enclosing `package.json`, rather than by how the path is spelled. A
path outside `node_modules` and the versioned package cache is somewhere a
human deliberately pointed OpenCode, so it is kept byte-identical, whatever
the directory is called and whether it is written as a path, a `file://`
URL, or a build output directory. An entry carrying plugin options keeps
its options. The published package name is appended only when nothing in
the config resolves to this plugin.

References the installer itself produced are still retired: a repeated bare
name, version pins, the former `oc-chatgpt-multi-auth` name, and paths into
`node_modules` or the versioned package cache.

The exit-time cache refresh deleted three paths recursively, each chosen
purely because its final segment matched a managed package name. A
developer who links a working checkout into the OpenCode cache so OpenCode
loads it - `npm link`, or a symlink under `node_modules` - therefore lost
that checkout the next time OpenCode exited with an update pending.

Every path is now resolved through its symlinks and must still be contained
in the OpenCode cache directory before it can be removed. A path that
escapes, a path that cannot be resolved, and the cache directory itself are
refused and logged rather than deleted.

Developing on this project means pointing OpenCode at a clone rather than
at the published package, but nothing said so, and the install commands
were presented without noting that they write the reader's real OpenCode
config.

README gains a section on that setup and on what the installer does with
it. AGENTS.md separates the installer from the standalone CLI commands it
had been listed beside, since only the installer writes config, and records
that a plugin entry is identified by what it resolves to rather than by its
last path segment. The setup skill tells an agent to read the existing
`plugin` array before installing, and to prefer `update` when the goal is
only a stale package cache.

OpenCode can load this plugin from the published package or from a
checkout a developer points it at, and at runtime the two are
indistinguishable unless the plugin asks. Several behaviours want the
answer: offering an npm update makes no sense for a build that npm did
not install, and a developer whose edits silently stopped taking effect
has nothing to look at.

`lib/plugin-origin.ts` resolves the answer from `import.meta.url` by
walking up to the nearest enclosing `package.json`, then classifies the
root: one under `node_modules`, or under `packages/` with a version
suffix, is package-manager output, and anything else is a location a
human chose. The version suffix is what keeps an ordinary monorepo that
happens to keep its packages in `packages/` from being mistaken for
OpenCode's plugin cache.

Each sighting is appended to `~/.opencode/oc-codex-multi-auth-origin.json`
rather than overwriting the previous one. A last-writer-wins marker would
be useless for the case it exists to explain: once a checkout has been
replaced, one load of the replacement would rewrite the record to confirm
the new state, erasing the evidence that anything changed. Keeping both
lets `findReplacedLocalCheckout` name the checkout that used to be live.

The file is written atomically through a temp file and rename, and every
read treats malformed or absent history as empty, so a corrupt record
degrades to "no history" instead of breaking startup.

A build loaded from a checkout carries whatever version its `package.json`
declares, which is almost always behind the published one. The daily check
compared the two, decided an update was available, and said so on every
start. Nothing about that was true or actionable: the published version
describes a package this process is not running, and the offered remedy -
evicting the OpenCode package cache - cannot update a build that does not
live there.

Worse, the toast points at the installer, and a developer who follows that
advice reinstalls over the very checkout they are working in. Silencing the
prompt removes the most common route into that mistake.

`checkAndNotify` now returns before the registry lookup when the caller
reports a local checkout, so no request is made, no toast is shown, and no
cache eviction is scheduled. `index.ts` resolves the origin once at startup
and passes it, logging the checkout path so it is visible which build is
live. The origin is also recorded at that point, skipped under a test
runner so suites never write to the history file.

Which build OpenCode loaded was invisible from inside the plugin, so a
developer whose edits had stopped taking effect had no way to tell whether
their checkout was still live. The config entry could have been replaced
weeks earlier and every diagnostic would keep looking healthy, because the
installed package is healthy - it is simply not the code being worked on.

`codex-status` now names the origin in every output mode, next to the
storage path that already answers the equivalent question about accounts.
`codex-doctor` reports it under the deep technical snapshot and, when the
origin history shows the plugin used to run from a checkout and now runs
from the installed package, raises a warning naming that checkout and when
it was last loaded.

The warning fires only in that direction. Moving between two checkouts is
an ordinary thing to do deliberately, and a developer who has gone back to
the published package on purpose is told once, with the path, rather than
being corrected.

Preserving a checkout entry only helps while the entry is still there. Once
a config has lost it - to an older installer, a hand edit, a restored
backup - the remaining entry is an ordinary published-package reference,
and nothing about it suggests the user ever wanted anything else. The
installer would go on registering the published package, correctly and
unhelpfully, every time.

The origin history the plugin keeps is the one record that knows better.
When the finished plugin list registers no checkout but the history shows
this plugin running from one, the installer names that path and the date it
was last loaded, and says how to point the entry back at it.

It reports rather than restores. History is evidence of what happened, not
authority over what should be registered now, and a user who deliberately
moved back to the published package would not thank an installer that kept
undoing it. A recorded path that no longer resolves to this package is
skipped, so a deleted or renamed checkout produces silence instead of
advice to point OpenCode at a directory that is gone.

This PR depends on acceptance of #259 and is branched off it, so the diff here currently includes that PR's three commits. The four commits belonging to this PR are the ones after them.

If #259 is accepted without changes, this one can be merged straight after it. If #259 changes during review, I will rebase this branch onto the merged result and update this PR.

Pull request overview

This PR adds runtime detection and reporting of which “origin” (installed package vs local checkout) the plugin is running from, and uses that information to adjust update-check behavior and diagnostics.

Changes:

  • Introduces lib/plugin-origin.ts to resolve/record plugin origin and maintain an append-only origin history file.
  • Skips daily npm update checks when the plugin is loaded from a local checkout, and tightens cache eviction safety via realpath containment checks.
  • Enhances codex-status, codex-doctor, and the installer to surface origin info and warn when a checkout was replaced by the installed package; adds tests and documentation.

  • resolvePluginOrigin() incurs two synchronous package.json reads in the common case: one (or more) during findPackageRoot() and another after the root is found. Consider refactoring the walk to return the manifest alongside the root (or otherwise reuse the first successful manifest) to avoid the extra sync filesystem read on startup/tool invocation.
/**

scripts/install-oc-codex-multi-auth-core.js:1

  • The origin history filename constant is duplicated between the installer (ORIGIN_HISTORY_FILE_NAME) and the runtime module (lib/plugin-origin.ts’s HISTORY_FILE_NAME / getPluginOriginHistoryPath). To prevent drift (one side changing without the other), consider consolidating this into a single shared source of truth—e.g., exporting a constant or helper from lib/plugin-origin and importing/using it here (or otherwise generating the path via a shared function).

Review of ndycode#259 found four ways the new classifier still reached the
wrong answer. Each one ends with OpenCode loading two copies of this
plugin, or none.

A relative entry was never resolved, so its package.json was never read.
OpenCode resolves such an entry against the config file that declares
it, so `./plugins/my-codex-fork` names a real checkout; the installer
saw an unreadable path, called it unrelated, and appended the published
name beside it. The declaring config directory is now passed down and
used to resolve relative entries FOR INSPECTION ONLY - the entry itself
is still written back exactly as the user spelled it.

A checkout and the published name could both survive. The published
entry was kept whenever it appeared, independently of any checkout, so
a config left by an older installer kept the duplicate registration
this change exists to repair. Registration is now decided once, across
the whole list, before any entry is kept.

A checkout of the FORMER package name satisfied that registration. It
is user-owned, so it is still never removed, but `oc-chatgpt-multi-auth`
is valid for cleanup and not as the registration the installer must
ensure - a config holding only a legacy checkout now also gets the
current package registered.

Windows reaches one directory under many spellings, so a `NODE_MODULES`
path there is the same package-manager output as `node_modules` and was
being preserved as if a human had chosen it. Segment comparison is now
case-insensitive on win32 only; elsewhere the two are different
directories and must stay so.

# Conflicts:
#	scripts/install-oc-codex-multi-auth-core.js
Review of ndycode#260 found the history file could lose the very sighting it
exists to preserve. Every OpenCode process records its origin at startup,
and this machine routinely starts dozens at once, so the read-modify-write
was a race in practice rather than in theory: two processes read the same
history and each wrote back its own snapshot, and whichever landed second
erased the other's origin.

The sighting that goes missing is the one worth having. A checkout being
replaced by the installed package is precisely two different origins
written close together, so the case the file is meant to report is the
case most likely to be lost.

Recording now takes the same kind of short lease the storage layer already
uses, and re-reads the history inside it, so each writer merges into what
is on disk rather than into what it read moments earlier. A process that
cannot take the lease records nothing and returns what is already there: it
will be started again, and a sighting arriving one startup later costs less
than a sighting overwritten.

The installer also classified entries without the config directory when
deciding whether a recorded checkout is still registered, so a checkout
registered by a relative path was reported as unregistered. It now uses the
same base directory as the rest of the installer's entry classification.

The history file name is spelled in two places, because the installer runs
before anything is built and cannot import the runtime module. A test now
pins the two spellings together; a silent disagreement would leave each
side reporting confidently about a file the other never writes.

Thanks — triage of all four findings raised here, plus the one Copilot suppressed.

6. Relative checkouts register twice — real, fixed in #259 and inherited here

@greptile-apps (P1, :283). This is the same defect as #259's :281, surfacing in this diff because this branch is stacked on that one. Fixed once, in the lower PR (a2ce671), and merged into this branch (2855a0b) rather than patched twice — so it leaves this diff automatically when #259 merges. The full reasoning and verification are in my reply there.

One consequence was local to this PR and is fixed in a396af5: findUnregisteredLocalCheckout classified entries without a base directory, so a checkout registered by a relative path looked unregistered and the installer would have printed the "your checkout is no longer registered" notice about a checkout that still was. It now uses the same paths.configDir as the rest of the installer's classification.

7. Concurrent writes lose history — real, fixed

@greptile-apps (P1, lib/plugin-origin.ts:190). This is the most valuable finding in the set and it is correct in every particular, including the observation that the Windows rename retries handle transient locks but do not serialize writers.

It is also not hypothetical on the machine this was written for: every OpenCode process records at startup and dozens start concurrently there. Worse, the sighting most likely to be lost is the one the file exists to report — a checkout being replaced by the installed package is two different origins written close together, so the race destroys exactly the evidence the feature was built to preserve.

Recording now takes a short lease using proper-lockfile, the same mechanism and calling convention lib/storage/transaction-lock.ts already uses, and — the part that actually fixes it — re-reads the history inside the lease, so each writer merges into what is on disk rather than into what it read moments earlier.

A writer that cannot take the lease records nothing and returns the existing history, rather than falling back to an unlocked write. That asymmetry is deliberate: the process is about to be started again, so a sighting arriving one startup later costs less than a sighting overwritten.

Verified rather than assumed. The new test drives recordPluginOrigin from two origins concurrently and asserts both survive; against the pre-fix implementation it fails, against the fix it passes.

8. Duplicated filename constant — real; pinned by test rather than consolidated

@copilot (:9). The hazard is real and I have taken the #258 treatment you suggested — a cross-file constant-agreement test — but not the consolidation, and I want to be explicit about why rather than let it look like an oversight.

scripts/install-oc-codex-multi-auth-core.js is plain JavaScript that runs from a freshly unpacked npm tarball via npx, before anything in dist/ necessarily exists, and lib/plugin-origin.ts is TypeScript compiled into dist/. The installer importing the runtime module would make config repair depend on a successful build — which is precisely the situation somebody runs the installer to get out of. (The one place the CLI does load from dist/, loadDistModules, fails loudly and deliberately when the build is missing.)

So the name stays spelled twice, and HISTORY_FILE_NAME is now exported and asserted equal to the installer's ORIGIN_HISTORY_FILE_NAME in test/plugin-origin.test.ts. A desync now fails CI instead of leaving each side reporting confidently about a file the other never writes.

Suppressed: two package.json reads in resolvePluginOriginreal, deliberately unchanged

Copilot suppressed this one, but it is accurate: findPackageRoot reads the manifest to locate the root, then resolvePluginOrigin reads it again for the version.

I am leaving it. It is one extra read of a file the OS has just cached, once per process start, and threading the manifest back out of the walk couples "where is the root" to "what does it say" for no measurable gain. Recording it here as a known, accepted redundancy rather than quietly declining it.

Testing

test/plugin-origin.test.ts is 22 tests, all passing, with two added: the concurrent-write case and the cross-file constant agreement. npm run lint, npm run build, and npm run typecheck are clean, and the four suites touching this work (plugin-origin, install-oc-codex-multi-auth, auto-update-checker, doc-parity) pass 110/110.

Two caveats on the full-suite figure, because both cost me time and the second could easily be mistaken for a code failure:

  • The machine ran at a load average above 50 throughout. test/index-retry.test.ts fails under that load and passes 6/6 when run alone, on this branch and on this branch's parent commit at the same moment — so it is contention, not a regression. I compared every failing file base-versus-branch back to back before concluding that.
  • One run failed with ENOSPC from a full /tmp tmpfs, not from anything in the diff. Test temp is now directed at a filesystem with room.

main-nowaker is being moved concurrently by other work; I have not touched it, and both of these branches are pushed for whoever integrates.

This PR is AI generated, but under direct supervision and on request of @Nowaker.

Thanks for the detailed triage. I rechecked the current implementation and agree that both original P1 findings are addressed.

  • Relative checkouts: classifyPluginEntry now resolves relative paths against the declaring config directory before walking for package.json, while entries without a base directory remain conservatively untouched. The added tests cover checkout roots, dist paths, and the end-to-end no-rewrite case (scripts/install-oc-codex-multi-auth-core.js).
  • Concurrent history writes: recordPluginOrigin now takes a proper-lockfile lease, re-reads the history inside that lease, merges the sighting, and refuses to perform an unlocked write if the lease cannot be acquired (lib/plugin-origin.ts). The concurrent Promise.all test verifies that all origins survive.

The duplicated filename is justified by the installer’s pre-build constraint and is guarded by the cross-file agreement test. The remaining duplicate manifest read is harmless startup overhead. I see no remaining merge blocker from these findings.

Nowaker added a commit to Nowaker/oc-codex-multi-auth that referenced this pull request Sep 17, 2026
Review of ndycode#260 found the history file could lose the very sighting it
exists to preserve. Every OpenCode process records its origin at startup,
and this machine routinely starts dozens at once, so the read-modify-write
was a race in practice rather than in theory: two processes read the same
history and each wrote back its own snapshot, and whichever landed second
erased the other's origin.

The sighting that goes missing is the one worth having. A checkout being
replaced by the installed package is precisely two different origins
written close together, so the case the file is meant to report is the
case most likely to be lost.

Recording now takes the same kind of short lease the storage layer already
uses, and re-reads the history inside it, so each writer merges into what
is on disk rather than into what it read moments earlier. A process that
cannot take the lease records nothing and returns what is already there: it
will be started again, and a sighting arriving one startup later costs less
than a sighting overwritten.

The installer also classified entries without the config directory when
deciding whether a recorded checkout is still registered, so a checkout
registered by a relative path was reported as unregistered. It now uses the
same base directory as the rest of the installer's entry classification.

The history file name is spelled in two places, because the installer runs
before anything is built and cannot import the runtime module. A test now
pins the two spellings together; a silent disagreement would leave each
side reporting confidently about a file the other never writes.

Recording where this plugin was loaded from takes a lockfile lease, and
proper-lockfile's default answer to losing one is `(err) => { throw err }`
(lockfile.js:213). That throw is raised from the timer that refreshes the
lease, so it lands outside every promise chain and no `.catch()` on the
caller can reach it: the OpenCode process hosting the plugin dies. A
stalled event loop past the ten-second stale window is enough to trigger
it, which on a machine running dozens of sessions is an ordinary Tuesday
rather than a fault. Writing one line of diagnostic history is not worth
an editor closing.

The lease now supplies its own handler, which records the loss and warns,
matching what `lib/storage/transaction-lock.ts` already does for the
storage and refresh leases. The write is then skipped, because whoever
reclaimed the lease owns the file now and writing the merged history read
before they arrived would drop their sighting - the clobber the lease
exists to prevent. This is the same answer already given to a lease that
cannot be acquired at all, arriving later.

The regression test drives the path directly by standing in for
proper-lockfile: it asserts a handler is supplied, that calling it does
not throw, and that nothing is written afterwards. Against the previous
revision it fails on both counts.

Compromised lease kills plugin — real, fixed in a502700

Confirmed rather than assumed, in the vendored copy: the default is
onCompromised: (err) => { throw err } (proper-lockfile/lib/lockfile.js:213),
invoked at :200 from the routine that refreshes the lease. That is a timer
callback, so the throw lands outside every promise chain — the .catch() the
plugin already wraps recordPluginOrigin in cannot see it, and the OpenCode
process hosting the plugin exits. Your trigger is the right one: passing the
ten-second stale window needs only a stalled event loop, which on a machine
running many sessions at once is ordinary rather than exceptional. Writing one
line of diagnostic history is not worth that.

The lease now supplies its own handler, which records the loss and warns. That
is the shape this repository already uses for its other two leases
(lib/storage/transaction-lock.ts:176 and :215), so this is now consistent
with them rather than an exception.

One step beyond the finding. You asked for the handler; the commit also
skips the write when the lease was compromised. Supplying a handler alone would
have left the more interesting bug: the merged history was read before the
reclaiming writer arrived, so writing it would drop their sighting — precisely
the clobber the lease exists to prevent. It is the same answer this function
already gives when the lease cannot be acquired at all, just arriving later.
The check sits after the merge and immediately before the write, mirroring
lease.assertValid() before persist in transaction-lock.ts:248.

On the coverage gap — correct. The concurrency test exercised only normal
acquisition. The new test stands in for proper-lockfile and drives the
compromised path directly: it asserts a handler is supplied at all, that calling
it does not throw, and that nothing is written afterwards. Run against the
previous revision it fails on both counts, the write assertion reporting

AssertionError: expected { version: 1, sightings: [ { …(6) } ] } to deeply equal { version: 1, sightings: [] }

which is the pre-fix code writing over the reclaiming process.

Gate on a502700: npm run typecheck, npm run lint, npm run build all exit
0; full suite 3600 passed, 1 skipped, 0 failed.

Classify the unversioned OpenCode cache path as managed.

normalizePluginList preserves packages/oc-codex-multi-auth as a local checkout because classification recognizes only versioned packages/*@* paths. clearCache then deletes that directory, leaving the config pointed at a missing plugin.

Pass the known cache root into classification. Treat only that cache root's unversioned and versioned package directories as managed. Do not classify every unversioned packages/ directory as managed, because that would affect monorepos. Add a regression test for the unversioned cache path.

Comment thread scripts/install-oc-codex-multi-auth-core.js Outdated
An entry pointing into OpenCode's package cache at
`<cache>/packages/oc-codex-multi-auth` survived normalization as a local
checkout, because classification recognized only the versioned
`packages/<name>@<version>` spelling the cache usually writes. The
unversioned directory is a cache layout too, and `clearCache` removes it
on the same run, so the installer preserved an entry and then deleted
what it pointed at. OpenCode then had a config naming a plugin
directory that no longer existed.

Spelling could not separate the two: `packages/oc-codex-multi-auth` is
also how an ordinary monorepo names its own package, and treating every
unversioned `packages/` directory as cache would retire those real
checkouts. Ownership can. The installer already knows its cache root and
already empties it, so an entry resolving to somewhere inside that root
is one the installer wrote and may retire, whatever it is called. A
monorepo lives elsewhere and is untouched.

Classification takes the cache root the same way it takes the config
directory, so the containment question is answered against a path the
caller supplies rather than one guessed here. Windows path casing folds,
since one directory is reachable there under several spellings.

Containment is compared on the path as written, without resolving
symlinks, which is the opposite of what the cache eviction path does and
is deliberate. Eviction decides whether to delete a directory
recursively, so it must refuse anything whose real location escapes the
cache. This decides whether an entry names something `clearCache`
removes, and `clearCache` removes the paths exactly as it spells them -
`rm` unlinks a symlink rather than descending into its target. Resolving
here would preserve an entry whose link is about to be unlinked out from
under it, which is the failure this commit exists to end.

…ackage

The note pointing a user back at a checkout OpenCode has run from
accepted the recorded path as long as any `package.json` could be found
at it. Paths get reused - a checkout deleted and an unrelated project
cloned into the same directory - and the installer would then recommend
that directory as somewhere to point OpenCode, naming this plugin while
describing somebody else's project.

The recorded sighting already carries the package name that was seen
there, so the two are compared. A directory that has become something
else produces no note at all, which is the right answer: there is
nothing to go back to.

The same call now also receives the cache root it was missing, so it
reads a plugin list by the same rules normalization just applied to it.
Without it a cache copy counted as a registered checkout here while
being retired there, and the two disagreed about the list they had both
just been handed.

…tform

Two ways the history could still lose a sighting it was supposed to
keep. Both are about the same guarantee - that every origin seen on a
machine stays on record - so they are answered together.

Ownership was checked once, before the replacement copy was written.
`writeFile` is the long part of that sequence, so a lease reclaimed
during it was reclaimed after the only check: the losing writer then
renamed its older snapshot over history the new owner had already
written, dropping exactly the sighting the lease exists to protect. The
question is now asked again immediately before the rename, which is the
only moment the replacement becomes visible to anyone else, and the
temporary file is discarded instead when the answer is no. `writeHistory`
reports whether it replaced anything, so a caller that lost the race
returns what is on disk rather than what it hoped to write.

Roots were compared verbatim. On Windows one directory is reachable
under several spellings, so `C:\Repo` and `c:\repo` took two slots in a
history bounded at ten and could evict a genuinely different origin
between them, and `findReplacedLocalCheckout` would read a re-cased
spelling of the current root as a checkout that had been replaced.
Comparison now runs through a key that folds case and separators on
Windows only - elsewhere those are different directories and must stay
so. The key decides matching alone: sightings keep the path as the run
that recorded them spelled it, so a reader is shown somewhere real.

`isPackageManagerRoot` folds segment casing the same way, so a
`NODE_MODULES` path is recognized as package-manager output rather than
being taken for a checkout and silently exempted from update checks.
The installer settled this for its own classifier already; the runtime
cannot import that plain-JS script, so the rule is stated once more here
rather than shared.

Each rule takes the platform as an argument so both sides of it can be
tested from either host.

Compare the registered checkout with the recorded checkout.

This guard returns null for any local checkout. A legacy checkout or a different current-package root can therefore suppress the notice for latest.root.

Select the latest sighting first. Suppress the notice only when a current-package config entry resolves to that recorded root, including entries that point to its dist directory.

Add a regression test with a recorded current-package checkout and a registered checkout at another root.
