Consensus review from an 8-model panel (Claude + GPT 5.4 Codex, Gemini 3.1 Pro, Kimi K2.5, MiniMax M2.7, GLM-5.1, Qwen 3.6), two convergence rounds. Reviewed against the numbered claims and disclosed residuals in the review-log comment; instances of a listed residual are not reported.
No blockers. 6 major, 6 minor, 3 nit. The major items are inline below; minor and nit items are in a separate comment.
Fix first: MAJOR #1 — when the engine can't be attributed, the call runs locally with no notice and no undetermined marker in the result. The only channel is a TUI toast, so in headless there is no signal at all. It fires on every affected session rather than under a race, and it means the pilot's own telemetry can't distinguish "routed" from "quietly didn't". A few lines in check().
The remaining majors read as reasonable pilot residuals. Note that MAJOR #2's inherited half (a mutable registry each handler re-resolves independently) and MINOR M0's inherited half (the attached outcome carrying no workspace identity, in engine-types.ts) both live below this PR in the stack.
The design itself held up well under seven independent reads — capability-scoped shadowing, the reachable() gating, canonicalType inverting DRIVER_MAP, and the announcement machinery were all singled out as correct, and the guard-ordering test genuinely proves its invariant rather than asserting it. Every finding here is about a seam, not the shape of the decision.

MINOR — workspace identity drops the credential scope, so a redirect can cross tenants
Severity note: raised by the panel as a blocker on the strength of "cross-tenant". Recording it as MINOR — each customer occupies a single tenant, so no customer can reach this. The only actor is an internal staff session switching tenants mid-flight, inside a roughly one-turn window. Real defect, narrow and internally-bounded trigger, cheap fix.
readLocalBinding is readLocalBindingScoped(...).binding — it discards the scope. The subsystem this sits on top of deliberately does not, and says why:
// engine-overlay.ts:151-156
/** Identity of the workspace a binding names: the credential scope it was
* read under plus the tenant-local id. */
function workspaceKey(binding: ScopedBinding): string {
return `${binding.scope ?? ""}|${binding.datamateId}`
}state.ts:195-205 exists purely to carry that scope (tenant|apiUrl): "Workspace ids are tenant-local; the scope is what tells the same id in two tenants apart."
Trace: a session attaches under tenant A / workspace 42. The user switches credential scope and links tenant B / workspace 42 before the next engine boundary. Then:
attested()passes — the settled outcome is{ kind: "attached"; available; declared?; missing? }(engine-types.ts:26) and carries no workspace identity at all.attributedTo()passes — the configured pin is--datamate 42, scope-free by construction.- the re-link guard at
precedence.ts:565passes — it compares42 !== Number("42").
Precedence engages and issues a redirect naming the engine tool that the pinned MCP wrapper still points at, which is tenant A's engine — so the query runs on the wrong credentials and is audited against the wrong workspace. Low-numbered id collisions across tenants (a demo workspace 1, a customer workspace 1) are ordinary.
It is silent when it happens: it would surface as a query in a customer's audit log that nobody on their side ran, not as anything visible in telemetry.
Fix — thread the scope through, as the overlay already does:
- read via
readLocalBindingScopedhere; - store
workspaceKey = \${scope}|${datamateId}`inPrecedenceinstead ofworkspaceId(precedence.ts:419,:565`); - carry the applied workspace key on the settled
attachedoutcome, and require settled identity, current binding and snapshot to match exactly; - when the scope is unavailable, run locally with an
undeterminednotice.
Note on ownership: the fix splits across the stack. Using the scoped reader is this PR. Putting identity on the attached outcome is engine-types.ts, i.e. #1167 — untouched here. Worth deciding which PR carries which half, or it falls between the two.

Recorded as a pilot residual per the severity note: single-tenant customers cannot reach it, and the fix rightly splits across the stack (identity on the attached outcome below this PR). Will be addressed with the scope-threading work rather than half-landed here.

MAJOR — time-of-check/time-of-use between the routing decision and the executed target
This pin, and the check at :497-501, close the window across the dbt await. But the routing decision was made earlier and elsewhere: Precedence.check() → resolveDefaultTarget (register.ts:139-160) does its own Registry.list().warehouses[0] read from inside the tool body, and the handler then resolves the target again, independently. The await Dispatcher.call(...) boundary and the handler's own awaits are enough for a queued concurrent mutation to land in between, so the comment's claim that this makes the decided and executed connection "the same by construction" is stronger than what the pin actually does.
Concretely:
- the guard sees an unserved DuckDB default; a concurrent
warehouse.removedrops it;sql.explainorschema.inspectthen picks the newly-first Snowflake connection and executes it locally, despite Snowflake being shadowed — unaudited execution on a served connection, the exact outcome this design exists to prevent; - for an explicit name, a concurrent
warehouse.addcan replace that name with a served type aftercheck()read it. The handler pins the already-replaced type and sees no subsequent change, so this check cannot detect that window.
Note also that this pin exists only in register("sql.execute") — sql.explain (:552-570) and schema.inspect (:678-691) have no equivalent guard at all.
Fix: make the decision and the target acquisition atomic — move the precedence check into the handler after it pins the target (passing sessionID through), or return a lease {name, canonicalType, generation} that handlers must revalidate. Apply it to all three ops, explicit names included.
Related, same seam: Precedence.check()'s await import("../native/connections/register") (precedence.ts:586-588) has no try/catch, and check() is called outside the surrounding try in all three tool bodies — so a throw there takes out sql_execute, sql_explain and schema_inspect together instead of failing open.
default-target.test.ts:123-151 does not prove its stated invariant: it calls the dispatcher directly, omitting the preceding precedence decision, which is where the race actually is.
There was a problem hiding this comment.
Partially addressed in 81d5e402f: the overclaiming comment is softened to what the pin guarantees, and check() now fails open with a stated reason on any internal throw (covers the uncaught lazy import ahead of all three tool try blocks). The pin extension to explain/inspect and the atomic-lease design are recorded residuals.

MAJOR — Config.invalidate() flushes the global cache and every instance's cache, once per turn; and a failed invalidation is trusted
Two things in these twelve lines.
(a) Blast radius. Config.invalidate() runs invalidateGlobal and invalidateAllInstances() (config/config.ts:827-831, ScopedCache.invalidateAll) — the call-site comment reasons about a per-instance cache, but this is process-wide. It runs whenever the cached pin already matches, which for an engaged session is every turn (refresh is called per turn from prompt.ts:1763-1774). In a long-running multi-directory serve, one active session's precedence refresh invalidates configuration for every other project, repeatedly, and active directories can end up thrashing each other's caches.
(b) A failed invalidation is swallowed. The .catch() logs and continues, so the second read() returns the same cached value, it matches expected, and routing engages on a pin that may no longer be on disk. If an IDE rewrote the entry from workspace 42 to 99 between turns and the invalidation fails, this returns the stale "42". Everywhere else this module refuses when it cannot establish attribution; this is the one path that proceeds instead — and it is the direction the function's own comment calls dangerous.
Fix: (a) don't invalidate globally on this hot path — expose a current-instance-only invalidation, do a narrow uncached read of the datamate entry, or use the overlay's attested applied identity (which would also address the scope blocker). (b) return null when the invalidation throws.
There was a problem hiding this comment.
(b) fixed in 81d5e402f: a failed invalidation returns null — attribution refuses rather than trusting the cached pin. (a) blast radius is a recorded residual: narrowing needs an instance-scoped invalidation surface, deferred with the attribution rework.

MAJOR — precedence ignores per-turn tool availability
refresh() is derived from the full materialised MCP map plus permission rules. But resolveTools in llm.ts:309-316 deletes any tool where input.user.tools?.[tool] === false, after precedence has been computed here.
So a request that disables datamate_snowflake_execute_database_query for the turn still gets sql_execute shadowed: the native description falsely claims redirection, and the redirect names a tool that is not in that turn's catalogue. A working local operation becomes a dead end.
reachable() was written to prevent exactly this class of dead end for permissions — the same reasoning applies to availability.
Fix: derive precedence from the effective catalogue after user.tools toggles are applied, or pass an availableToolKeys set into refresh() and require materialised and available. Keep the permission-rule check as a separate condition.
There was a problem hiding this comment.
Recorded as a pilot residual: real, narrow trigger (a per-turn tool toggle on exactly the engine key), and the fix belongs with a broader refresh-input rework. The dead end is at least no longer silent — the redirect target missing from the catalogue surfaces as a failed call rather than nothing.
Consensus review — minor, nit, and rejected findingsCompanion to the inline review (6 major, no blockers). Panel: Claude + GPT 5.4 Codex, Gemini 3.1 Pro, Kimi K2.5, MiniMax M2.7, GLM-5.1, Qwen 3.6 — two convergence rounds. Reviewed against the numbered claims and disclosed residuals; instances of a listed residual are not reported. MINORM0. Workspace identity drops the credential scope — Recorded as MINOR rather than the blocker the panel first ranked it. Each customer occupies a single tenant, so no customer can reach it; the only actor is an internal staff session switching tenants mid-flight, in a roughly one-turn window. Real defect, cheap fix, deliberately not scheduled — details and the ownership split with #1167 are in the inline comment. M1. It reads M2. Hardcoded engine-tool conventions fail silently — Both are hand-maintained. A new engine integration ( M3. The dbt-fallback redirect names the fallback connection and offers no way to insist on dbt — With a dbt project on DuckDB (known, unserved) and a served Postgres as the registry fallback, the call is redirected to M4.

Two of these are worth calling out as genuinely well done:
- Fixes 1 and 2 compose correctly. A failed invalidation now returns
null→derive()recordsunattributed→check()states the reason. Claim 1 ("fails open with a stated reason") now holds on the path where it previously didn't, including headless. - The notice actually reaches the caller. Deleting the notice-prepending in
annotate()breaks tests, so the reason lands in the tool result rather than only in the verdict object or a toast.
The register.ts comment is now accurate about what the pin guarantees ("narrows, not closes"), and the guard-ordering and reachable() gating from the original review continue to hold. The routing code reads as ready.
One thing to fix first: three of this PR's tests fail when run alongside the rest of the directory
bun test test/altimate/default-target.test.ts -> 12 pass, 0 fail
bun test test/altimate/altimate-core-rewrite-verify.test.ts \
test/altimate/default-target.test.ts -> 29 pass, 3 fail
bun test test/altimate/ -> 4381 pass, 3 fail
The three:
the default target survives a concurrent registry change > a connection dropped during the dbt await does not silently redirect the calla connection replaced under the same name is not executed on the old verdict > a same-name replacement of a different type is refused, not run locallya connection replaced under the same name is not executed on the old verdict > a same-name rewrite that keeps the type still runs
Cause: altimate-core-rewrite-verify.test.ts:69,211 runs beforeEach(() => Dispatcher.reset()), which clears the process-global nativeHandlers map and the lazy registration hook (dispatcher.ts:35-41). Bun runs both files in one process, so default-target.test.ts — which imports Dispatcher but never re-registers — then fails with No native handler for sql.execute.
Why it matters more than ordinary flake: these are exactly the tests that prove the stale-connection guard, i.e. the concurrency property this PR adds. In any directory-wide run they don't execute, so that guard is currently unproven.
Fix: re-register in default-target.test.ts's setup, following the pattern already used in altimate-core-e2e.test.ts:158, altimate-core-native.test.ts:172 and altimate-core-stress-e2e.test.ts:38 — each carries the comment "Re-register handlers in case another test file called Dispatcher.reset()". Alternatively, have the rewrite test restore the handlers it clears.
Minor: two of the six fixes have no regression test
Reverting either leaves the suite fully green (111 pass, 0 fail), so both can regress silently:
attributedTo'sreturn nullon a failedConfig.invalidate()(precedence.ts:305). The attribution tests assignprecedenceInternals.attributedTodirectly, which bypasses the production implementation entirely — so the suite structurally cannot reach this path. Covering it needs an injectable config-read/invalidate seam. This is the security-direction fix (refuse rather than trust a stale "pinned to us"), so it's the one most worth protecting.- The named unrecognised-type notice (
precedence.ts:617). No test passes a named warehouse whose configured type doesn't canonicalise. Awarehouse: "mystery"case asserting the notice andprecedence: "undetermined"would cover it.
Nit
resetForTests() clearing attachOutcome is correct but untested — every current setup overwrites the seam immediately, so nothing would notice if the deletion were dropped again.
No new defect found in the routing logic itself. Ledger items from the previous round — credential scope, the config-cache blast radius, the remaining decision/execution window, per-turn tool toggles, the attribution test seam, and the hardcoded engine tool names (which check out correctly against the engine: Snowflake serves execute/explain/table stats, BigQuery, PostgreSQL and Databricks execute only, and databricks_execute_sql really does break the convention) — are treated as accepted and are not re-raised here.

#1168 made the engine win: a shadowed warehouse call executes nothing and returns a redirect naming the engine tool. It did not make the model *pick* the engine first, so every session pays a wasted turn learning the rule. The only model-visible steering today is a sentence `describeNativeTool` appends to a description whose first line already matches user intent ("Execute SQL against a connected data warehouse."), and it never names the engine key — so even an obedient model cannot comply without a probe call. The routing table the model needs already exists as `inventoryLine`, and goes only to a TUI toast. Nothing in the system prompt mentions the workspace. `session/system.ts:129-142` records this repo's own benchmark finding: a lazily-described capability fired in "<1% of tool calls", and guidance placed at the END of a section was "treated as background reference rather than binding directive" while the same content placed FIRST was applied. The precedence suffix is exactly that shape. So state it in the system prompt instead, per turn, naming the exact engine keys, and say the converse explicitly so unserved types keep running locally. Purely additive by construction — 118 insertions, 0 deletions: - `awareness.ts` renders a string and nothing else. It does not touch `check()`, `derive()`, `redirectFor()` or any tool body, so which calls are shadowed and what a shadowed call returns are unchanged. - It returns "" in every state except a bound, attributed workspace with materialised engine tools. A session without a workspace assembles a byte-identical system prompt to before this commit. - `servedInventory()` is a projection over the snapshot the guard already uses, filtered through the same `servedFor`/`reachable`, so the section can never advertise a routing `check()` would not perform, nor one the caller's agent is forbidden to follow. - No tool descriptions change, so no existing description assertions move. Deliberate details: - Per capability, not per warehouse type. BigQuery serves execute only, so its line says explain and inspect stay on the local tools — claiming the type would steer the model off the only tools that work there. - The converse paragraph is never dropped under the char cap; without it the section reads as "prefer the workspace for everything", which is the over-steering failure this most needs to avoid. - The escape hatch speaks rather than falling silent: engine tools can still materialise with `--integrations=local` on, so silence would leave the model free to use tools it can see and should not. - An agent denied the engine keys renders no section, matching what precedence actually does for it. Verification: `bun run typecheck` clean. 19 new tests (14 awareness, 5 precedence), all passing. Full `test/altimate/` sweep goes 4420 -> 4439 pass with the same 3 pre-existing failures present on the untouched base commit (cross-file pollution in `default-target.test.ts`, which passes 12/12 in isolation on both). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…engine Shadow a native warehouse capability only when the bound workspace's engine materialised the matching tool and attach attests the engine is its own (outcome `attached` plus the configured pin); redirect to the exact engine tool after the native safety checks; fail open with a reason otherwise. `--integrations=local` turns it off. Restacked onto the derived-overlay attach; the allowlist is exactly `attached`.
…ormat tools.ts The two `describeNativeTool` call sites used the single-line marker form, which the strict marker guard that runs on pushes to main does not recognise. No behaviour change.
- `unattributed` and an unrecognisable named connection type return an `undetermined` notice instead of a bare RUN — deliberate disablement stays silent; uncertainty never is (a toast is UI, not the correctness channel) - `check()` fails open with a stated reason on any internal throw - a failed config invalidation refuses attribution instead of trusting the cached pin; `resetForTests` releases `attachOutcome`
… refusals - `default-target.test.ts` re-registers the native handlers in `beforeAll`: `altimate-core-rewrite-verify.test.ts` resets the dispatcher, and the three concurrency tests here dispatch `sql.execute`, so in a directory-wide run they failed with "No native handler" and the guard they prove went untested. - `precedenceInternals.config` seam over the config read and invalidation behind the real `attributedTo`, so its refusal on a failed invalidation is exercised through production: a pinned-to-us entry with a throwing invalidate derives `unattributed`; the same entry with a working invalidate attributes; a post-invalidate re-read pinned elsewhere refuses. - A named connection whose configured type does not canonicalise returns the `undetermined` notice; `resetForTests` releases the attach and config seams.
- `warehouse_list` re-validates the precedence snapshot against the current binding before annotating rows, as the query tools already do, so a mid-turn re-link is not reported as served by the old workspace. - Drift in the hand-maintained engine-tool map is visible: an execute tool from an integration the module does not know is warned once per session and shadows nothing, and a test pins every known integration to a canonical local driver type. - The dbt-fallback redirect says what the call would do — try dbt, then fall back — instead of naming the fallback as the served target, and that the dbt path cannot be chosen from the tool. - `resetDbtAdapter` no longer breaks single-flight: a superseded attempt releases only the slot it owns. Adapter creation is asserted single-flight, including across a reset. - Tests and comments say the dbt branch is unexercised outside a dbt project; the escape hatch is documented as process-wide; the module header states the audit boundary. Databricks (execute-only) redirect covered.

…ces it The existing test asserted the redirect wording through a named warehouse, which never takes the dbt-fallback branch. This reaches that branch through the pure decision function and pins what the reworded notice must say: the call would try dbt first and fall back to the named connection, and the dbt path cannot be chosen from the tool.

Declined — this is the design, and it is the property the consensus review singled out as correct: shadowing is keyed per capability on the key that actually materialised, never on a per-integration capability matrix. If a BigQuery explain key ever materialises, redirecting explain to it is right, because the tool exists; today it does not materialise, and "sql_explain on BigQuery is not redirected to a tool that does not exist" is pinned by a test. A hardcoded capability gate would be exactly the hand-maintained drift M2 warned about.

P3: A no-warehouse sql.execute routing decision calls resolveDefaultTarget → ensureDbtAdapter, which constructs the real dbt adapter (Python bridge, manifest rebuild, file watchers) every session, including for calls that are redirect-shadowed and never use dbt, and for calls that run locally via the registry.

Declined for this PR: resolveDefaultTarget deliberately mirrors the handler's own resolution — sql.execute with no warehouse tries dbt first, so the adapter is what decides the target, and ensureDbtAdapter is single-flight and cached once per process (the handler pays the same cost on its first call). Deriving the type from the manifest alone would decide differently from the handler in the cases where they disagree, which is the mis-routing this module exists to prevent. Recorded as a follow-up to revisit when the dbt-first path is revived (it is unexercised outside a dbt project today).
…nreadable link is unknown, not unbound - Engine tools are recognised by the MCP client that served them, not by the `datamate_` prefix alone: `MCP.tools()` stamps every entry with its client, and another server named e.g. `datamate_snowflake` flattens to the same key shape. Such keys confer no precedence and are reported once per session. - The binding is read through the strict reader: a cache or credentials file that is present but unreadable settles `binding-unreadable`, which `check()` reports as undetermined with the reason, and which invalidates a routed snapshot for that reason rather than as a re-link. - A derivation that throws settles `derive-failed` — local execution with a stated reason — instead of failing the turn's tool resolution. - The re-link guard runs only when a redirect is about to be returned; a call that runs locally regardless does not pay for the binding read. - A superseded dbt-adapter attempt returns its result but no longer publishes it over the newer attempt's cache, and `tryExecuteViaDbt` executes on the adapter it was handed rather than re-reading the mutable global. - The drift warning covers every warehouse capability shape, not only execute. - `schema_inspect` validates its inputs before consulting precedence, as `sql_explain` does, through a shared `input-validation` module. - The guard-order test restores `ALTIMATE_INTEGRATIONS` it deletes.

When session A first catalogs workspace A, another session re-links the directory to workspace B, and A reaches a later model step, this refresh reads B's live MCP tools before pinTurnTools restores A's first catalog. A's retained attached outcome contains no workspace identity, so B's current binding and configured pin pass attribution and the native call redirects as if B's tool were materialized; however, the model-facing key is then replaced with A's pinned wrapper, which points to the closed client after the engine replacement. This reproducibly makes the final catalog disagree with the precedence snapshot, violating Claims 1/1a and 4; derive precedence from the post-pin catalog or retain A's first precedence snapshot for the turn.
Useful? React with 👍 / 👎.

Accurate trace, declined as an instance of the disclosed residuals rather than fixed here. What it produces is the attach contract's R2 exactly: with concurrent sessions in one directory, another session's boundary can replace the shared engine mid-turn, and this turn keeps the tools it catalogued — the redirect names datamate_<tool>, the model-facing key is A's pinned wrapper (pinTurnTools restores it after catalog()), that wrapper's client is closed after the replacement, and the call fails. It never runs on workspace B, and the disagreement lasts until the next turn boundary re-derives both. The missing piece you name — identity on the retained attached outcome so attribution can refuse B's binding for A's engine — is R19 on the attach log and the lease work that is the GA gate. Retaining the turn's first precedence snapshot alongside the pinned catalog is the right companion change and is recorded as a residual on this PR's log to land with that work; it needs turn state threaded through resolveTools, which is more than a round-cap change should carry.

Declined as a recorded residual rather than fixed here: this is M0 on this PR's companion review ("workspace identity drops the credential scope") and R19 on the attach log — recorded as MINOR because each customer occupies a single tenant, so the only actor is an internal session switching tenants mid-flight within one turn. The fix splits across the stack (scope on the snapshot here, identity on the attached outcome below) and is scheduled with the scope-threading work, not half-landed in this PR. The consensus re-review treats it as accepted.
…shot it was published for Eviction drops a session's publish chain, so a session recreated before its old line lands has a second publication running unchained. The completion guard checked only that the session existed; a stale completion arriving last could then overwrite the new record and make the next refresh repeat the newer line. The guard now requires the stored snapshot to be the one the attempt was published for.

…ncarnation, not the snapshot The identity guard checked the snapshot object, but a multi-step turn refreshes per step and each refresh replaces the snapshot while the same line is still being said — so a delivery landing after the second refresh was never recorded and the next turn repeated the line. A per-session incarnation token, minted when a session is first remembered or recreated after eviction and dropped with it, keeps both properties: ordinary refreshes still record, a completion for a session evicted and recreated mid-flight does not.

Consensus re-review — acb4c7126 — approving
Ready to merge for the pilot. 0 critical, 0 major, 2 minor, 5 nit. Six reviewers, quorum met;
converged in one round with no reviewer opposing the merge. Both reviewers that opened against
merging moved on evidence, and the one remaining objection asked for a finding to be ranked
lower, not higher.
The three round-2 findings are closed, and I checked them by running them
- Test isolation.
bun test test/altimate/twice: 4426 pass / 644 skip / 0 fail, 5070
tests across 158 files. The exact pair that produced round 2's failure —
altimate-core-rewrite-verify.test.ts+default-target.test.ts, previously 29 pass / 3 fail
— now runs 33 pass / 0 fail. A second reviewer ran the same suite independently and got
identical numbers.tsgo --noEmitclean. attributedTorefusal on a failed invalidation and the named unrecognised type are
both covered now, and the coverage is real: reverting each fix fails exactly the test named in
your disposition.
Fix verification by mutation — revert the fix, see whether a test notices
| # | Fix | Correct? | Test protects it? |
|---|---|---|---|
| 1 | materialisation filtered by the serving MCP client | yes | yes — 2 tests fail |
| 2 | unreadable link settles binding-unreadable |
yes | yes |
| 3 | throwing derivation settles derive-failed |
yes | yes |
| 4 | drift warning covers every warehouse capability shape | yes | yes |
| 5 | schema_inspect validates before precedence |
yes | yes — 2 tests fail |
| 6 | dbt cache writes ownership-guarded | yes | yes |
| 7 | tryExecuteViaDbt executes on the handed adapter |
yes | no |
| 8 | announcement recorded against the session incarnation | yes | yes, doubly |
Fix 8 is the best piece of work in the PR. Reverting it to each of its two predecessors fails
a different test: the bySession.has() form fails the eviction case, the
bySession.get() === result form fails "two refreshes sharing one in-flight delivery record it
once, not never". The incarnation token is the first form that satisfies both, and the suite
proves that rather than assuming it. A fix that took three attempts and ends with a test
catching each earlier attempt is the opposite of a fix that happens to pass.
I also confirmed the client-stamp filter is real in production rather than only in the unit
test: both resolvers pass the raw MCP.tools() map, and every entry is stamped with the client
that served it, so servedByForeignClient has the signal it depends on.
Minor
M1 — warehouse_list is the one path that still fails silently.
warehouseListNotes returns an empty map when the snapshot cannot be re-validated, which now
covers relinked and unreadable. warehouse-list.ts keys its whole rendering off
notes.size, so an empty map means the plain three-column table: no "Served by" column, and no
statement that anything was refused. A listing after a mid-turn re-link is byte-identical to the
listing of a project that was never bound.
This is the module's own principle — nothing is ever silent — unmet in the place the model reads
before it picks a tool, and it is now the last such place: every other surface states its
reason, including the two reasons added this round. It stays MINOR because the query tools do
say it; precedence.test.ts:1013 pins that the next check() carries a "re-linked" notice. Only
the inventory lacks one.
snapshotState() already distinguishes relinked from unreadable — returning that alongside
the notes and rendering a one-line header would close it.
M2 — sql_explain and schema_inspect have no connection-identity pin.
This PR gave sql.execute one: it pins fallbackName/fallbackType before the dbt await and
refuses if the connection's canonical type changed underneath. The two sibling handlers call
Registry.get(name) with no equivalent check, so a concurrent warehouse.add that replaces a
connection between the routing decision and the resolve leaves them executing locally on a
connection that would have been redirected.
Narrower than the case that motivated the pin — no long await here, so the window is the
return-and-dispatch gap — and it fails open: local execution, never another workspace's
engine. One reviewer opened this at MAJOR and settled at MINOR on that failure direction. Worth
closing for consistency, since it is precisely the race the new guard exists to close.
Nits
- N0 (future risk, not a current finding).
decideForTarget's step-2 branch is
if (target.source === "dbt" && target.fallback), not gated on the dbt type being
undetermined. So a dbt target of a known, unserved type with a served registry fallback
redirects too, and a query that would have run on the dbt target runs on the fallback. The
docstring justifies step-2-before-step-3 by the undetermined case; the determined-and-unserved
case takes the same branch. Recorded rather than raised: the branch is unreachable while
ensureDbtAdaptercannot initialise, and theviaDbtFallbackmessage discloses the behaviour
in full and names the escape hatch. Worth settling deliberately when the dbt path is revived,
rather than rediscovered then. - N1. Fix 7 has no regression test — reverting it leaves
default-target.test.tsat 13/13.
No weight while that path cannot initialise; noting it so it is a choice. - N2.
session/tools.tsmerges the ruleset throughPermission(V1) while
session/prompt.tsusesPermissionNext(V2), andreachable()consumes the result through
PermissionNext.evaluate. Bothmergeimplementations arerulesets.flat()today, so there
is no divergence — but the two resolvers are meant to be incapable of describing a tool
differently, and this is the one place they could drift. - N3. The
fallbackTypere-check is a synchronous no-op on the named-warehouse path: with
params.warehouseset the dbt block is skipped, so nothing awaits between the read and the
re-check. It guards only the no-warehouse path, while its message implies both. - N4.
unreachable()omitscapabilityandconnectionwhileredirectForincludes them.
No correctness impact — it issues no redirect — but telemetry loses a dimension.
Raised and rejected
Recorded so they are not re-litigated next round. Each was checked against the code, not waved
off:
- Cross-test interference in
test/altimate/, raised at CRITICAL — refuted by execution:
three clean full-directory runs, two of them mine and one from another reviewer. - A test seam leaking across files, raised at MAJOR — not reachable; no file under
test/
touches it. - The guard-order tests are vacuous, raised at MAJOR — they are not. "An ordinary read on the
same connection is still redirected" is a positive control proving the connection really is
shadowed, so a hard-denied statement reaching precedence first would return a redirect instead
of throwing. The ordering is proven. resetForTestsdoes not clear thewarnseam — it does.sql_executewithwarehouse: ""mis-routes — traced both sides.decide()treats the
empty string as falsy and takes the default-target path; the handler computes
params.warehouse || Registry.list().warehouses[0]?.nameand gates the dbt attempt on
!params.warehouse. They agree, so the header wording landed in915020f98is accurate.
Not re-raised
Everything already dispositioned stays settled and is not a finding here: credential scope on the
snapshot, per-integration capability gating, resolveDefaultTarget constructing the adapter,
later-step precedence against the pinned catalog, the hardcoded engine tool names (verified
correct against the engine's own source in an earlier round), and the disclosed per-turn /
256-session / removed-client residuals.
What is done well
- Splitting
unboundfrombinding-unreadableis the right distinction, and it is carried all
the way through — derivation, thecheck()notice,inventoryLine, and snapshot
re-validation each treat "unknown" differently from "opted out". - The client-stamp filter closes a genuinely non-obvious hole: a foreign server named
datamate_snowflakeflattens to the same key shape as the engine's own tools, and only the
stamp separates them. - Attribution is defence-in-depth rather than one check — attach outcome plus configured pin,
with disk re-confirmation only in the enabling direction, and a test that forces a stale cached
pin and asserts refusal. - Moving the re-link guard onto the redirect path answers the cost objection without weakening
it: it still runs on every path that could send a call elsewhere. canonicalTypeinvertsDRIVER_MAPinstead of restating it, so a driver added there cannot
silently desync from anything keyed on driver identity.
None of the open items blocks the pilot. M1 is the one I would take first — it fires on every
affected listing, and the listing is what the model reads to choose a tool.

Issue for this PR
Closes #1155
Type of change
What does this PR do?
Stacked on #1167 — review that first; this PR is the commit on top. It is the precedence change from #1156 restacked onto the overlay attach; the mechanism is unchanged, the attach seam it reads is now the overlay's.
When a bound workspace's engine is attached, the model gets two ways to do the same thing: the native warehouse tools over local keychain connections, and the engine's MCP tools over the workspace's SaaS connection. Nothing chose between them, so the model picked whichever description read better — and that pick decided which credentials ran the query and whether it was audited (engine calls are audited server-side; native ones are not).
This adds a per-session decision: shadow only what materialised and is attributable to the bound workspace; anything undetermined runs locally and says why; nothing is silent.
attached(the overlay's own pinned engine, connected at this turn boundary) and the configured entry's pin names the bound workspace. Any other outcome, or none, fails open with a reason.--integrations=localturns it off for a session.Two deliberate deviations: the guard needs a companion call to attach the fail-open notice, which a pre-execution check cannot do; and an adjacent warehouse-type reporting bug is left alone, since fixing it changes a shipped telemetry field.
How did you verify your code works?
bun run typecheckclean; precedence, default-target, guard-order and workspace suites pass (161 tests across the six directly affected files; the tool/native/prompt suites green). The union test now asserts the allowlist is exactlyattachedover the whole outcome union, so a future outcome kind refuses routing by default.End-to-end rows from #1156 (shadow marking, redirect with a proven no-local-execution control, DuckDB control, default target, model following the redirect unprompted, write confirmation, escape hatch) are re-run on this stack and recorded in the review-log comment below before this leaves draft.
GitGuardian flags a masked placeholder (eight literal asterisks) in a help-text snapshot that only moved columns; it is present unchanged on the base commit and is not a credential.
