What does this PR do?

The bug. A bare import("snowflake-sdk") inside the compiled Bun binary resolves against bunfs, which has no node_modules. An SDK the user had already installed was therefore invisible to the runtime, which reported it as "not installed". That one root cause sits under all nine issues above — five of which were filed automatically by the telemetry scanner, at 76 / 47 / 39 / 19 / 14 hits in single two-hour windows.

Why it works. New packages/drivers/src/resolve.ts, with all twelve drivers routed through it. loadOptionalDriver() tries the ambient resolver first — so dev, the monorepo and any currently-working install behave exactly as before — and only on a resolution failure searches real directories on disk: the managed install dir, ALTIMATE_BIN_DIR (exported by the npm wrapper), NODE_PATH, the project and its parents, and the executable's own tree. It then imports the resolved absolute path rather than the bare specifier, which is the part bunfs cannot do.

Three supporting changes:

  • Install location. On-demand installs go to <XDG_DATA>/altimate-code/drivers. ~/.altimate/bin is rebuilt by the curl installer's self-upgrade, which is exactly how hand-installed drivers were being wiped (Autoupdate wipes manually-installed optional warehouse drivers (snowflake-sdk) from ~/.altimate/bin/node_modules #1075).
  • Honest failures. A package that is present but throws on import is now reported as a broken install rather than a missing one, so users are not sent to reinstall what they already have. DriverNotInstalledError names the exact install command and every location searched, replacing twelve copies of a bare npm install <pkg> hint.
  • New warehouse_install_driver tool. warehouse_add now reports driver readiness at the point it can still be acted on. That check is filesystem-only and deliberately does not install — adding a connection must not block on a network npm install. (My first attempt did install inline; it broke five tests by blowing a 500ms budget, which was the tests correctly catching a bad design.)

A pre-existing bug found on the way. The driver list is declared in four places and had drifted: mongodb had a driver module and a workspace dependency, but was missing from the binary's optionalExternals (so it was bundled into the binary instead of installed on demand) and from the published package's optional peer dependencies (so it was never surfaced to users). Both fixed, with driver-catalogue.test.ts now pinning all four declaration sites to DRIVER_PACKAGES.

build.ts's autoloadPackageJson: true also picked up a comment. That flag is load-bearing — it is what lets the compiled binary resolve an external package from disk at all — and removing it would break every driver in the shipped binary while the test suite stayed green.

How did you verify your code works?

The unit tests use fixture packages, so I also verified in the environment the bug actually occurs in: a binary compiled with the production Bun.build options, run from an empty cwd with no NODE_PATH, against a real pg install in an isolated directory.

bare import("pg")   : FAILED: Cannot find package 'pg' from '/$bunfs/root/probe.js'   <- the bug
loadOptionalDriver  : OK, keys=Client,Connection,DatabaseError,Pool,Query             <- the fix

Same for the subpath (mysql2/promise) and scoped (@clickhouse/client) specifier shapes.

Suite Result
packages/drivers unit 162 pass, 0 fail
packages/opencode (altimate + tool + install) 4,712 pass, 0 fail
Driver e2e, DRIVER_E2E_DOCKER=1 (Postgres, DuckDB, ClickHouse, MongoDB, data-diff) 140 pass, 0 fail
Snowflake finops e2e, real warehouse 29 pass, 0 fail
bun turbo typecheck 13/13

Two things reviewers should know:

  • bun test alone reports the driver e2e files as passing while 242 of 253 tests silently skip. They need DRIVER_E2E_DOCKER=1 and warehouse credentials to mean anything.
  • drivers-snowflake-e2e.test.ts shows 40 pass / 5 fail against a real warehouse, but fails identically on main with the same credentials — those five assume a purpose-built test account (password auth, a PUBLIC schema, a specific role). Environmental, not from this change.

Not verified by me: Windows path handling and npm.cmd resolution in installOptionalDriver.

Screenshots / recordings

Not a UI change.

Checklist

  • I have tested my changes locally
  • I have not included unrelated changes in this PR

Risk: the ambient-resolution path is tried first and is unchanged, so any install that works today keeps working. The new behaviour only runs where the old code would have thrown "not installed".

…hem missing

A bare `import("snowflake-sdk")` inside the compiled Bun binary resolves
against bunfs, which has no `node_modules`. An SDK the user had already
installed was invisible to the runtime, which then reported it as "not
installed" — the single root cause behind nine open issues, five of which
were filed automatically by the telemetry scanner.

Add `packages/drivers/src/resolve.ts` and route all twelve drivers through
it:

- `loadOptionalDriver()` tries the ambient resolver first (unchanged
  behaviour in dev and the monorepo), then resolves against real
  directories: the managed install dir, `ALTIMATE_BIN_DIR`, `NODE_PATH`,
  the project and its parents, and the executable's own tree.
- Installs land in `<XDG_DATA>/altimate-code/drivers`, which no upgrade
  path touches. `~/.altimate/bin` is rebuilt by the curl installer's
  self-upgrade, which is how hand-installed drivers were being wiped.
- A package that is present but fails to load is now reported as a broken
  install rather than a missing one, so users are not sent to reinstall
  what they already have.
- `DriverNotInstalledError` names the exact install command and every
  location searched, replacing twelve copies of a bare `npm install` hint.

Also add the `warehouse_install_driver` tool, and have `warehouse_add`
report driver readiness at the point it can still be acted on. The check is
filesystem-only and deliberately does not install: adding a connection must
not block on a network `npm install`.

Fix pre-existing drift in the driver catalogue. `mongodb` had a driver
module and a workspace dependency but was missing from the binary's
`optionalExternals` (so it was bundled instead of installed on demand) and
from the published package's optional peer dependencies (so it was never
surfaced to users). `driver-catalogue.test.ts` now holds all four
declaration sites to `DRIVER_PACKAGES`.

Verified in the environment the bug actually occurs in: compiled a binary
with the production `Bun.build` options and confirmed bare `import("pg")`
fails with `Cannot find package 'pg' from '/$bunfs/root/…'` while
`loadOptionalDriver` loads the real module. Same for the subpath
(`mysql2/promise`) and scoped (`@clickhouse/client`) specifier shapes.

Tests: 162 drivers unit, 4,712 opencode, 140 Docker-backed driver e2e
(Postgres, DuckDB, ClickHouse, MongoDB, data-diff), 29 real-Snowflake
finops e2e. Typecheck clean.

📝 Walkthrough

Walkthrough

Changes

Optional warehouse drivers now use a shared resolver that searches runtime package locations, distinguishes missing and broken modules, and installs drivers into managed storage. Connectors, warehouse tools, build configuration, publishing metadata, and catalogue tests now use the shared driver catalogue.

Optional driver flow

Layer / File(s) Summary
Driver catalogue and package resolution
packages/drivers/src/resolve.ts
Defines driver metadata and resolves optional packages from managed, environment, project, and executable-adjacent locations.
Driver installation and resolver validation
packages/drivers/src/resolve.ts, packages/drivers/test/resolve-unit.test.ts
Adds npm installation, managed storage, post-install verification, forced repair, concurrent-install serialization, and resolver tests.
Connector adoption of shared loading
packages/drivers/src/*.ts
Updates warehouse connectors to use shared optional-driver loaders while preserving connector behavior and export normalization.
Warehouse readiness and installation tools
packages/opencode/src/altimate/tools/warehouse-add.ts, packages/opencode/src/altimate/tools/warehouse-install-driver.ts, packages/opencode/src/tool/registry.ts
Reports missing drivers during warehouse addition and registers a tool for validation, installation, aliases, and structured results.
Build, publishing, and catalogue consistency
packages/opencode/script/build.ts, packages/opencode/script/publish.ts, packages/opencode/test/altimate/driver-catalogue.test.ts
Aligns build externals and optional peer dependencies with the driver catalogue and validates catalogue consistency.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to e2c28

The PR improves warehouse SDK discovery and installation repair, but current code can still overlap installs, leave timed-out installer processes modifying managed files, and make forced repairs ineffective. These bounded correctness risks can leave driver installations inconsistent, so the PR needs fixes or explicit owner acceptance before merge.

…alled packages, azure auth, type aliases

Findings from the multi-model consensus review of #1122. Each was reproduced
before being fixed.

**Installing a driver deleted the previous one.** `installOptionalDriver` ran
`npm install --no-save`, so npm treated every already-installed driver as
extraneous and pruned it. Reproduced on npm 11.12.1: installing `mysql2` into a
prefix holding `pg` printed `added 12 packages, and removed 14 packages`. A user
adding a second warehouse silently lost the first — re-creating the exact defect
this module exists to fix. The install now saves to the directory's manifest,
which makes it genuinely additive (verified across three drivers).

**A half-installed package reported as installed.** `resolveOptionalPackage`
fell back to returning the package directory when `require.resolve` failed, so
an empty `node_modules/pg` resolved successfully and `isDriverInstalled` was
true. `warehouse_install_driver` then answered "already installed, no action
taken" and the driver could never be repaired. Resolution now requires a
manifest and an entry file that exists, and keeps searching later roots instead
of returning a path the caller cannot import.

**Azure AD auth used the pattern this PR removes.** `sqlserver.ts` still called
`import("@azure/identity" as string)`, which cannot resolve inside the compiled
binary, so an installed `@azure/identity` was invisible and every Azure AD login
silently fell through to the az CLI. Routed through a new `loadOptionalPackage`
(soft variant that returns undefined rather than throwing, since this caller has
a real fallback), and declared as a non-driver external.

**Six warehouse types never got a readiness note.** `DRIVER_MAP` routes 18 type
strings onto 13 drivers, but `driverForWarehouseType` matched only the 12
canonical names, so a connection added as `postgresql`, `mariadb`, `mssql`,
`fabric` or `mongo` skipped the check added for #61 — the silent-broken-
connection case that issue is about.

**Test quality.** The review mutation-tested `isModuleNotFound` by deleting it
and all 22 tests still passed; its fixture was never ambiently resolvable, so
the branch was unreachable. Applying the same technique to the new fixes showed
the first half-installed test was also vacuous. `isModuleNotFound` and
`npmInstallArgs` are now exported and pinned directly, and four mutants — always-
missing predicate, `--no-save` restored, manifest check removed, bare-directory
return — each fail at least one test.

Tests: 172 drivers unit (was 162), 4,712 opencode, 140 Docker-backed driver e2e.
Typecheck clean.

The install cannot be cancelled.

execute ignores the tool context, so no abort signal reaches installOptionalDriver. runNpm in packages/drivers/src/resolve.ts lines 357-383 only stops the child process on its own 180-second timeout. If the user aborts the tool call, the npm child keeps running and keeps writing into the managed driver directory. Thread the abort signal through installOptionalDriver and kill the child when it fires.

Tie DRIVER_NAMES to DRIVER_PACKAGES. The catalogue tests do not import DRIVER_NAMES. Updating DRIVER_PACKAGES and the tests’ hardcoded lists can still leave a driver unavailable in warehouse_install_driver and driverForWarehouseType. Derive the Zod tuple from DRIVER_PACKAGES or add a test that compares both lists.

spawn with shell: true builds a shell command string.

args come from npmInstallArgs(DRIVER_PACKAGES[driver]), and DRIVER_PACKAGES is a fixed catalogue, so no external input reaches the shell today. The pattern is still fragile: any later change that passes a caller-supplied package name into runNpm becomes command injection. Consider resolving the npm executable per platform and dropping shell: true.

🛡️ Proposed hardening
-    const child = spawn("npm", args, { cwd, shell: true, stdio: ["ignore", "pipe", "pipe"] })
+    const command = process.platform === "win32" ? "npm.cmd" : "npm"
+    const child = spawn(command, args, { cwd, shell: false, stdio: ["ignore", "pipe", "pipe"] })

Note that shell: false changes the error surface on Windows when npm.cmd is absent; the existing error handler already maps that to exit code 127.

The docstring does not match the return value.

The comment states that the function returns the package directory when no CommonJS entry can be named. entryFromManifest only returns a file path, and the loader imports the result directly. A directory path would fail the import() at line 300. Align the comment with the implementation.

…lemetry, quoting

CodeRabbit and cubic-dev-ai findings on #1122. Each verified before fixing.

**A missing transitive dependency read as a missing driver.** `isModuleNotFound`
matched any "Cannot find module/package" text, but a driver whose own dependency
tree is incomplete raises exactly that shape — observed for real inside a
compiled binary as `Cannot find package 'pg-protocol' from '.../pg/lib/
connection.js'`, where pg itself is installed. The predicate now takes the
specifier and, when the runtime names the module it could not find, only counts
a name matching what was asked for. Without a specifier it stays conservative.

**A broken install could not be repaired.** `warehouse_install_driver` gated on
`isDriverInstalled`, which only asks whether the package resolves. A copy that
resolves but throws on import — a native addon for another platform, or a
half-written install — answered "already installed", so the one command that
could fix it declined to run. It now probes an actual load.

**Failed installs were recorded as successes.** `Tool` reads
`metadata.success === false` as its soft-failure signal (tool/tool.ts), and every
sibling warehouse tool sets it. This tool omitted it, so a failed install skipped
failure telemetry entirely.

**Install hints broke on paths containing spaces.** The printed
`npm install --prefix <dir>` is meant to be pasted; an unquoted path split and
npm received the wrong prefix. Added `shellQuote` and applied it at both sites.

**Two test-quality fixes.** CodeRabbit and cubic independently flagged that
"does not fall back when an ambiently-resolvable package fails to load" never
reaches the branch it names — its fixture is not ambiently resolvable, so the
disk fallback handles it first. Renamed to what it actually proves, with the
ambient branch now pinned directly through `isModuleNotFound`. Separately, a
comment claimed the catalogue test kept the tool's `DRIVER_NAMES` and alias map
in step with `DRIVER_PACKAGES`; no such test existed. It does now, and it also
asserts every `DRIVER_MAP` type resolves to an installable driver — removing the
alias map fails it, which is the #61 gap this PR set out to close.

Tests: 177 drivers unit (was 172), 4,714 opencode. Typecheck clean, 0 lint errors.

… copy shadowing a good one

Second bot round on #1122. The headline finding is that my previous commit's
repair path did not work.

**The reinstall never ran.** `warehouse_install_driver` gained a load probe so a
resolvable-but-unloadable driver would be rebuilt — but `installOptionalDriver`
short-circuits on `isDriverInstalled`, a resolution-only check, and returned
`installed: true, alreadyPresent: true` without invoking npm. The probe changed
nothing and the tool reported a success it had not performed. cubic-dev-ai
flagged this three times over. Installs now take a `force` option for callers
that know something the resolution check cannot, and the tool passes it exactly
when the package resolves but fails to import.

**A broken ambient copy hid a healthy managed one.** After an ambient import
failed with anything other than a resolution error, the loader rethrew
immediately, so installing a good copy into the managed directory could never
take effect. Resolution now continues to the search roots, and the ambient error
is only surfaced when nothing else loads.

**Concurrent installs could corrupt the managed directory.** Two installs
running npm against one manifest are serialized per target directory.

**Windows install hints were unusable.** `shellQuote` emitted POSIX single
quotes, which cmd.exe and PowerShell do not understand, so any path containing a
space produced a command that could not be run. It is now platform-aware.

**Test honesty.** The catalogue test asserted only that a registry type resolved
to *something*; a stale alias naming an uninstallable driver would have passed.
It now checks membership in DRIVER_PACKAGES. More importantly, the first attempt
at the ambient-shadowing test was vacuous in the same way three earlier tests
were — its fixture was not ambiently resolvable, so the branch under test was
never reached, and the mutant survived. It now writes a genuinely
ambient-resolvable fixture into this package's node_modules and removes it
afterwards. Mutants for all three fixes were confirmed to fail.

Tests: 182 drivers unit (was 177), 4,714 opencode. Typecheck clean.

🌐 Web query:

npm install --force documentation force fetching package already present

💡 Result:

When you run npm install with the --force flag, npm is instructed to fetch remote resources even if a local copy of the package already exists on disk or in the cache [1][2]. According to the official npm documentation, this flag ensures that npm ignores the existing local copy and retrieves the resource again [1][3]. However, it is important to note the following limitations and nuances: 1. Scope of --force: The --force flag is specifically designed to force fetching from remote registries (such as registry.npmjs.org) [4]. It may not always behave as expected when dealing with local file paths (e.g., local.tgz files), where npm might continue to serve a cached version due to integrity checks in the package-lock.json file [4]. 2. Resolving Conflicts: In some legacy contexts or specific dependency tree scenarios, --force is also used to override npm's refusal to install a package that has an identical name to the current package [5]. 3. Alternative Troubleshooting: If --force does not successfully update a package (common when dealing with local file changes or stuck cache entries), developers often resolve the issue by running npm cache clean --force or by temporarily removing the package-lock.json file to force a fresh re-evaluation of dependencies [4].

Queue each install behind the current in-flight tail.

Several callers can read the same pending promise. After it settles, each continuation starts performInstall without checking installsInFlight again. Those npm installs then overlap in the same directory.

Create and register a chained promise before starting the next install.

Proposed fix
-  const pending = installsInFlight.get(dir)
-  if (pending) await pending.catch(() => {})
-  const run = performInstall(driver, packages, dir, options)
+  const pending = installsInFlight.get(dir)
+  const run = Promise.resolve(pending)
+    .catch(() => undefined)
+    .then(() => performInstall(driver, packages, dir, options))
   installsInFlight.set(dir, run)

As per coding guidelines, protect shared file-write state from async races.

In `@packages/drivers/src/resolve.ts` around lines 450 - 459, Update the install
serialization around installsInFlight and performInstall so each caller creates
and registers a chained promise behind the current per-directory tail before
starting its install. Ensure concurrent callers await the newly registered chain
rather than independently starting after the same pending promise settles, while
preserving cleanup of the directory’s tail only when it still references that
chain.

P2: The per-directory install serialization only holds for two concurrent callers. When three or more installs target the same dir, callers queued behind the first in-flight promise each create and register their own run without re-checking the map, so two npm runs can overlap on the same manifest — the exact inconsistency this block exists to prevent. Re-read the map after awaiting the pending promise.
