What does this PR do?

Read this first — the diagnosis changed. Field verification against the real rig showed the first version of this PR did not help. --dir still returned "no tables", nothing was created anywhere on disk, and the store was byte-identical before and after. Pointed at a store that does not exist, the run returned "no tables" with no error at all, with or without --dir.

So the reported defect was not primarily silent creation. A failure was shaped like success at every layer between the driver and the model:

  1. (config.path as string) ?? ":memory:" in both file-backed drivers. Any failure to carry a path became a successful connection to an empty in-memory database — worse than silent creation, because it leaves nothing on disk to explain the empty answer.
  2. sql.execute never throws; it returns { columns: [], rows: [], row_count: 0, error } (register.ts:437), demoting the error to a field on a success-shaped result.
  3. formatResult() returned the literal string "(0 rows)" for row_count === 0 and never read error. An agent asking what tables exist was told the warehouse was healthy and empty, then offered a tip about query optimization.

assertStoreExists() was never bypassed — it fired, and its message was discarded one layer above. My test proved the guard worked only because it called Registry.get() directly instead of the path the product takes. The compiled-binary arms now go through Dispatcher.call("sql.execute"), and the rendering is tested through the sql_execute tool itself.

Reproduced on unmodified main at the tool layer: output: "(0 rows)\n\nTip: Use sql_analyze to check this query...".

Added: requireStorePath() (a missing or empty path is rejected; :memory: must be asked for), sql_execute surfacing result.error via normalizeError, and test/altimate/warehouse-failure-visibility.test.ts — six tests, three failing on main, including the two cases that must not change: an explicit :memory:, and a genuinely empty result set still rendering as (0 rows).

#1210 tracks the broader class: ten more tools call the dispatcher and never check error.

Passing --dir made a populated warehouse store read as empty with no error at all. Two independent defects composed to produce it, and each is fixed separately.

1. A relative store path followed the working directory.

--dir calls process.chdir(args.dir) (packages/opencode/src/cli/cmd/run.ts:412). ConnectionRegistry.load() stored the path field verbatim, so a relative path in ~/.altimate-code/connections.json was resolved by the driver against whatever cwd the process had at open time. --dir therefore re-pointed an existing connection at a different file.

resolveStorePaths() now absolutizes a relative path once, at config-load time, against the directory that declared it:

Source Base
~/.altimate-code/connections.json ~/.altimate-code (the config file's own directory)
<project>/.altimate-code/connections.json <project> (the project root)
ALTIMATE_CODE_CONN_* the project root

I chose the declaring directory rather than the project root for everything because the global config is shared across every project — a path relative to "wherever you happen to be" has no stable meaning there, while a path relative to the config file does. The project-local config and the env vars are already scoped to one project, so the project root is the natural base for those. Absolute paths and non-file targets are passed through untouched. warehouse_add persists the absolute form for the same reason — otherwise it writes a cwd-dependent entry into the shared global config.

Two things a Codex review turned up here, both fixed:

The project root is Instance.directory, not process.cwd(). A server session or run --attach never chdirs — it carries the project in the instance context and leaves the working directory wherever the server was launched. localConfigPath() already read process.cwd() before this PR, so it was already looking for the project-local config in the wrong place; absolutizing at load time would have baked that mistake into the saved global config permanently. projectRoot() prefers Instance.directory and falls back to cwd when there is no instance context — early CLI paths and unit tests, where cwd is the right answer because run --dir has already chdir'd.

Relative SQLite file: URIs are deliberately left alone, and filed as #1209 with the evidence. They follow cwd the same way, and worse — the create guard cannot catch them, because the failure is opening the wrong existing database rather than making a new empty one. I implemented the rewrite, and then removed it: bun:sqlite parses file: as a URI on macOS, where I reproduced the decoy read, but appears to treat it as a literal filename on Linux, where my test failed in CI, and Windows is unverified. A rewrite changes which database opens, so shipping one across platforms it has not been proven on would create the same class of defect this PR fixes. #1209 records the reproduction, the four separate regressions the attempt produced during review, and what a correct implementation needs.

SQLite shares the flaw. Its create: !isReadonly was the same hazard as DuckDB's, and it is fixed the same way. Of the other file-backed possibilities, only these two take a local path; the remaining drivers are network-backed and cannot conjure a store. Note the existing test readonly connection does not create nonexistent file already asserted this property for read-only SQLite connections — this PR extends the same guarantee to read-write ones.

Not overlapping the driver-resolution work. #1122, #1192, #1198 and #1201 all deal with loading the driver module (bunfs bare-specifier resolution, install locking, open timeouts). None of them touches path resolution or create-on-open. #1122 landed in main while I was working; this branch is rebased on top of it and its loadOptionalDriver() change to duckdb.ts sits directly above my four added lines with no conflict. #1198 is still open and edits the same connect() function, so expect a small textual conflict there — my change is four lines at the top of it, before tryConnect is defined.

How did you verify your code works?

Compiled binary, production build options, unrelated working directory. A bun test run cannot see this defect — the package's own node_modules stays reachable and the cwd is the runner's, not the rig's. So the proof runs a binary compiled the way script/build.ts compiles the shipped one (bundled sources, warehouse SDKs external, no bunfig/dotenv autoload), started from a directory unrelated to both the store and the project, and given --dir.

The store is seeded with a table named zorbulax_ledger, so a pass cannot come from anything except actually reading the file.

Before, on unmodified main:

{"ok":true,"cwd":".../project","tables":[]}

files created under the --dir target:
  .../project/warehouse.db       4096 bytes
  .../project/warehouse.db-wal      0 bytes
  .../project/warehouse.db-shm  32768 bytes

After:

{"ok":true,"cwd":".../project","tables":["zorbulax_ledger"]}

files created under the --dir target:
  (none)

The DuckDB arm behaves identically and leaves a 12,288-byte stray .duckdb file, which matches the stray 12 KB file an earlier investigation found in the wrong directory.

packages/opencode/test/altimate/store-path-resolution.test.ts compiles that binary in beforeAll and runs five arms: the reported case; a missing store that must fail loudly; a project-local config; a server-style request driven through Instance.provide with a decoy config and store planted in the launch directory, so a wrong resolution reads plausible wrong data rather than nothing; and an explicit create: true that must still work. The arms that can leak assert that no stray database file appears anywhere. Three of the five fail on unmodified main, which I confirmed by reverting only the source changes and re-running. The child process is also stripped of any ambient ALTIMATE_CODE_CONN_* variable, since those override both config files and would otherwise decide the assertions.

packages/drivers/test/file-store-guard.test.ts covers the guard directly: path classification (:memory:, md:, s3://, Windows drive letters), the DuckDB guard firing before any Database is constructed, and the SQLite read/refuse/create-on-opt-in paths.

Gates, all from a fresh bun install in this worktree:

  • bun test --cwd packages/drivers — 235 pass, 0 fail (7 files)
  • bun test --cwd packages/opencode — 11,562 pass, 9 fail across 12,394 tests / 606 files. All nine failures are pre-existing and live outside test/altimate: five in test/mcp/headers.test.ts, one each in test/server/httpapi-experimental.test.ts, the mcp HttpApi status endpoint, test/release-validation/mcp-datamate-893-codex.test.ts, and test/cli/run/run-process.test.ts. None of those files imports anything this PR touches, and I confirmed it directly: with my source changes reverted to origin/main, the same MCP/HTTP failures reproduce. The whole test/altimate tree — which is where every warehouse, driver, and connection test lives — is green: 4,231 pass, 0 fail across 152 files
  • bun turbo typecheck — 13/13 successful
  • bun run script/upstream/analyze.ts --markers --base origin/main --require-markers --strict — no upstream-shared files modified; 35/35 marker files valid
  • bun run script/upstream/analyze.ts --branding — pass
  • bun run lint — 1 error, pre-existing and environmental: typescript(tsconfig-error): Cannot find type definition file for 'bun-types', from script/upstream/tsconfig.json:6, which this branch does not touch and which has no bun-types install to resolve against. My changed files lint with 0 errors of their own.
  • prettier — my changed files introduce no formatting drift; registry.ts was clean at HEAD and is re-formatted, the other touched files were already unformatted before this PR and are left alone rather than reformatted as noise.

Nine existing tests relied on create-on-open to build their own scratch store and now pass create: true: four in schema-cache.test.ts, two in drivers-e2e.test.ts, three in driver-security.test.ts (which mocks the duckdb module outright, so its fixture files never existed on disk). Those are behaviour changes to the tests, not workarounds — each of them is a case where the caller genuinely does intend to create the store.

What I did not verify. Two things, stated plainly.

The full CLI end to end with a live model. altimate-code run --dir needs an LLM to invoke a warehouse tool, so the compiled-binary proof drives the same registry and driver code through a fixture entrypoint that reproduces run.ts's --dir chdir exactly, rather than through the agent loop.

The DuckDB arm inside the automated test. On Bun 1.3.14 a compiled binary resolves absolute module paths against the new cwd after any process.chdir(), so a --dir invocation could not load the external duckdb addon at all — the same cwd-prefix defect #1201 repairs, not something introduced here. After rebasing onto #1122 the new loadOptionalDriver() does find the addon past a chdir, but on my machine it then fails on @mapbox/node-pre-gyp not resolving out of the Bun store through an absolute-path import, which is again #1122/#1201 territory. So the automated arms drive SQLite (built into Bun, no addon), and the DuckDB evidence above was captured with the addon bundled into the probe. packages/drivers/test/file-store-guard.test.ts covers the DuckDB guard directly, and the guard is engine-independent — it runs before either driver constructs a Database.

DuckDB and SQLite now reject missing local stores unless create: true is set. Relative paths resolve against their declaring configuration directory. Driver callers, documentation, error reporting, and tests now use and validate these semantics.

Changes

File-store safety

Layer / File(s) Summary
Store guards and driver enforcement
packages/drivers/src/file-store.ts, packages/drivers/src/duckdb.ts, packages/drivers/src/sqlite.ts, packages/drivers/src/index.ts, packages/drivers/test/*
Shared helpers classify paths, require explicit paths, enforce explicit creation, and reject missing stores before opening. Unit and driver tests cover local, remote, in-memory, read-only, existing, and missing stores.
Stable connection path resolution
packages/opencode/src/altimate/native/connections/registry.ts, packages/opencode/test/altimate/fixtures/store-path-probe.ts, packages/opencode/test/altimate/store-path-resolution.test.ts
ConnectionRegistry resolves relative paths against global, project, or environment configuration directories. Compiled-binary tests cover populated, missing, project-local, and explicit-creation cases.
Explicit creation callers and documentation
packages/opencode/src/altimate/native/local/*, packages/opencode/src/altimate/tools/warehouse-add.ts, packages/opencode/test/altimate/drivers-e2e.test.ts, packages/opencode/test/altimate/schema-cache.test.ts, packages/drivers/test/driver-security.test.ts, docs/docs/configure/warehouses.md, docs/docs/drivers.md
Local scratch stores and test databases pass create: true. Documentation and warehouse_add describe creation defaults and stable path resolution.
SQL failure reporting
packages/opencode/src/altimate/tools/sql-execute.ts, packages/opencode/test/altimate/warehouse-failure-visibility.test.ts
sql_execute renders error-carrying results as errors. Tests preserve empty-result rendering for genuinely empty queries.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to aef0a

The PR now resolves file-backed warehouse paths consistently, prevents unintended store creation, and surfaces execution failures instead of reporting empty results. Merge readiness remains moderate because parallel tests can interfere through shared state and temporary files, SQL failures may expose sensitive connection details, and some programmatic or multi-project paths can still bypass the new resolution behavior.

Poem

I’m a rabbit guarding each store,
No empty files appear at the door.
Paths hold still when directories change,
create: true makes intent plain.
DuckDB and SQLite now report failure.

P2 Badge Restrict the scheme check to supported non-file targets

On POSIX, relative local filenames such as data:warehouse.duckdb are valid, but this pattern classifies every two-character-or-longer prefix followed by : as non-local. Consequently, resolveStorePaths() leaves the path cwd-relative and assertStoreExists() skips its existence check; DuckDB can then create an empty file after --dir, recreating the silent-empty-warehouse failure this change is intended to prevent. Exempt only known remote forms (or URI forms containing ://) rather than every scheme-shaped local filename.

- sqlite: path (file path)

- sqlite: path (file path), create (optional, default false)
File-backed stores (duckdb, sqlite): the store must already exist — connecting never creates it, because an empty database answers every query with no rows. Pass "create": true only when the store is meant to be created. A relative "path" is resolved against the directory of the config that declares it (the global config resolves against ~/.altimate-code), never against the current working directory; prefer an absolute path.

P2 Badge Describe warehouse_add's actual relative-path base

When the model invokes warehouse_add with a relative file path, this instruction says it will resolve under ~/.altimate-code, but Registry.add() resolves it against process.cwd() and persists the resulting absolute path (registry.ts:497-500). A model following the tool contract can therefore connect to a different same-named database than intended; the tool description should state that relative paths supplied to warehouse_add are project/cwd-relative, or the implementation should use the advertised global-config base.

`--dir` calls `process.chdir()` (`cli/cmd/run.ts:412`). `ConnectionRegistry`
never absolutized the `path` field, so a relative store path in a connection
config resolved against whatever working directory the process happened to
have when the driver opened it. Both file-backed drivers then answered the
miss by CREATING an empty database — `new duckdb.Database(path)` in
`drivers/src/duckdb.ts`, `create: !isReadonly` in `drivers/src/sqlite.ts`.
Every query afterwards succeeded and returned zero rows, with no error and no
fault signal for a caller to key on.

Two fixes, either of which breaks the chain; both are needed because the
second is the root hazard and is independent of `--dir`:

1. Resolve store paths deterministically. `resolveStorePaths()` absolutizes a
   relative `path` once, at config-load time, against the directory that
   declared it — global config against `~/.altimate-code`, project config and
   `ALTIMATE_CODE_CONN_*` against the project root. A later `chdir` cannot
   move it. `warehouse_add` persists the absolute form for the same reason.

   The project root comes from `Instance.directory`, not `process.cwd()`. A
   server or `run --attach` session never chdirs — it carries the project in
   the instance context and leaves cwd at the server's launch directory — so
   cwd there is somebody else's project. `localConfigPath()` had that bug
   already; absolutizing at load time would have baked it in permanently.

2. Never conjure a store that was meant to exist. New
   `drivers/src/file-store.ts` holds `assertStoreExists()`, which both
   file-backed drivers call before opening: a missing local file throws an
   error naming the path it looked for. Creation is opt-in via `create: true`,
   which `schema_sync` and `test_local` — the two tools that deliberately
   materialize a scratch store — now pass. Exempt from the check: the exact
   string `:memory:`, an empty path, and scheme-qualified targets (`md:`,
   `s3://`, `ducklake:`, anything a DuckDB extension provides), which the
   driver reports as an unknown scheme rather than creating. Only the EXACT
   `:memory:` — DuckDB writes a real file for `:memory:named` and for `:foo`,
   so those stay inside the guard. Windows drive letters stay paths.

`bun:sqlite` rejects an options object with no open flag, so the SQLite driver
now passes `readwrite` explicitly where `create` used to imply it.

Relative SQLite `file:` URIs are deliberately NOT handled here, and are filed
as #1209 with the evidence. They follow cwd the same way, but `bun:sqlite`
parses `file:` as a URI on macOS and appears to treat it as a literal filename
on Linux, and Windows is unverified. A rewrite changes which database opens,
so shipping one across platforms it has not been proven on would create the
same class of defect this fixes.

Verified through a compiled binary built with the production build options,
invoked with `--dir` from an unrelated working directory. Before: `tables: []`
plus a stray `warehouse.db` (+ `-wal`, `-shm`) written into the `--dir` target;
the DuckDB arm left a 12,288-byte stray `.duckdb`. After: the real table, and
nothing created. `test/altimate/store-path-resolution.test.ts` compiles that
binary and runs five arms — including a server-style request driven through
`Instance.provide` with a decoy config and store in the launch directory — of
which three fail on unmodified main.

Existing tests that relied on create-on-open to build their own scratch store
now pass `create: true`.

…ows)"

Field verification against the real rig showed the first version of this fix
did not help: `--dir` still returned "no tables", nothing was created anywhere
on disk, and `assertStoreExists()` produced no visible error even when pointed
at a store that does not exist. The diagnosis was wrong, not the measurement.

A failure was shaped like success at every layer between the driver and the
model, so three separate things had to be true for the agent to be misled, and
all three were:

1. `drivers/src/duckdb.ts` and `drivers/src/sqlite.ts` read
   `(config.path as string) ?? ":memory:"`. Any failure to carry a path — a
   config the registry never loaded, a field under another name, a lookup that
   fell through — became a successful connection to an empty in-memory
   database. That is worse than the silent creation this PR already closed: a
   stray file can at least be found afterwards, whereas this leaves nothing on
   disk to explain the empty answer. `requireStorePath()` now rejects a missing
   or empty path. `:memory:` is still available, but only when asked for.

2. `sql.execute` never throws. It catches every connection and query error and
   returns `{ columns: [], rows: [], row_count: 0, error }`
   (native/connections/register.ts:437). So the loud error from (1) and from
   `assertStoreExists()` was demoted to a field on a success-shaped result.

3. `formatResult()` in `tools/sql-execute.ts` returned the literal string
   `"(0 rows)"` whenever `row_count === 0` and never read `error`. An agent
   running `SELECT ... FROM information_schema.tables` against an unresolvable
   warehouse was told, in effect, that the warehouse was healthy and empty —
   then offered a tip about query optimization. `sql_execute` now surfaces the
   error the way `schema_inspect` already did, via `normalizeError`.

So `assertStoreExists()` was never bypassed. It fired, and its message was
thrown away one layer above. A guard whose failure cannot reach the caller is
not a guard, which is why the new tests drive the layers the product actually
uses: the compiled-binary arms now go through `Dispatcher.call("sql.execute")`
rather than reaching the driver via `Registry.get()`, and the rendering is
tested through the `sql_execute` tool itself.

`test/altimate/warehouse-failure-visibility.test.ts` covers all three: a
pathless config, a missing store, and an error-carrying result that must not
render as `(0 rows)` — plus the two cases that must NOT change, an explicit
`:memory:` and a genuinely empty result set from a healthy warehouse. Three of
its six fail on unmodified main, as do three of the five compiled-binary arms.

P2 Badge Keep the DuckDB availability probe runnable

When the DuckDB addon is installed, probeDuckDB() in packages/opencode/test/altimate/drivers-e2e.test.ts:71-95 still calls connect({ type: "duckdb" }); this new rejection is caught and reported as duckdbAvailable = false, causing every test.skipIf(!duckdbAvailable) DuckDB E2E test to be skipped even though the driver is available. Update the probe and the other in-memory fixtures in that suite to pass path: ":memory:" explicitly so CI continues exercising DuckDB.

P2 Badge Align the optional-path documentation with the new rejection

The warehouse documentation still tells users that path is optional and may be omitted for an in-memory DuckDB connection, but requireStorePath() now rejects every omitted path. A user following this table with { "type": "duckdb" } therefore gets a missing-path error instead of the documented in-memory database; either mark the field required and remove the omission guidance or preserve the documented fallback.

Scope temporary test fixtures per test.

Both new suites keep temporary-directory state at module scope and perform manual cleanup. Parallel tests can therefore share files or observe another case's cleanup. Use await using tmp = await tmpdir() inside each test and derive the store and binary paths from that fixture.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Isolate all process-global test state.

This teardown resets Registry only. The registered sql.execute stub and ALTIMATE_TELEMETRY_DISABLED value remain after the test. The file also states that Dispatcher.reset() leaks between test files. A concurrent Bun test can receive the stubbed dispatcher or modified telemetry setting.

Use a test-local dispatcher seam or isolated process. Restore the prior environment value and reset every shared service in teardown. As per coding guidelines: tests with dispatchers or similar shared state must provide teardown and isolation safe for parallel bun test execution.

SUGGESTION: Redundant type cast — result is already SqlExecuteResult

Dispatcher.call("sql.execute", ...) returns a value typed as SqlExecuteResult, whose error field is already error?: string. normalizeError accepts unknown, so the as SqlExecuteResult & { error?: unknown } cast adds nothing (the intersection collapses error back to string). Simplify to normalizeError(result.error).

Suggested change
const responseError = normalizeError((result as SqlExecuteResult & { error?: unknown }).error)
const responseError = normalizeError(result.error)

SUGGESTION: The sql.execute stub is never torn down and leaks into other test files

The second describe registers a global sql.execute stub and resets the dispatcher only in beforeEach. Nothing clears it in afterEach/afterAll, so the stub remains in nativeHandlers after this file finishes and can mask the real handler for any later test file sharing the process (the file's own header notes Dispatcher.reset() state leaks across files in Bun). Add afterEach(() => Dispatcher.reset()) to the second describe to restore isolation.

Heads-up for whoever merges this with the other one: #1198 and #1204 conflict, and afterwards three tests fail for a reason that is not a defect in either PR

I hit this building a combined binary for a benchmark rig. Recording it here because the resolution otherwise exists only in a throwaway branch I have deleted.

The conflict is in packages/drivers/src/duckdb.ts, on the same lines:

Keep both. They are independent changes that happen to touch adjacent lines, and dropping either silently removes behaviour the other depends on — a store path that fails loudly instead of becoming :memory:, and an open deadline that no longer fails a healthy store. The resolution is simply the two blocks in sequence:

// altimate_change start — a missing path must fail loudly, not become :memory:
const dbPath = requireStorePath(config, "DuckDB")
// altimate_change end
// altimate_change start — configurable open budget
const { ms: openTimeoutMs, source: openTimeoutSource } = resolveOpenTimeoutMs(config)
// altimate_change end

Then three of #1198's tests fail, in packages/drivers/test/driver-security.test.ts:

  • retries with READ_ONLY when the first open fails with DuckDB's real lock text
  • does not claim a non-contention lock failure as a foreign lock
  • wraps a lock error on an explicitly read-only open, and does not retry it

They open /tmp/test.duckdb, which does not exist. The tests mock the duckdb module so the file never needed to be real — but requireStorePath does a genuine filesystem check and refuses before the lock logic ever runs, with DuckDB database file not found.

The fix is the convention already in that file. #1204 added create: true to the older cases at lines 181, 408 and 433; the three newer #1198 cases need the same. With that, packages/drivers is 292 pass / 0 fail.

I verified this resolution by building and running it, not by reading the diffs — but I have deliberately not pushed it into either PR, since both belong to someone else to land. Flagging it so three red tests are not misread as a defect in either change.
