Adds Odin read-only query tools - #6214

The five named query flows Odin exposes - logs, metrics, users, virtual keys, providers/models - plus a log drill-down and a filter-space discovery tool. Pure library over the logging plugin's LogManager: no routes, no model calls. All five take the same filter object, mapped one-to-one onto logstore.SearchFilters, so one parser and one scope path serve every flow. Three properties hold for every tool, each with a test: Scope. Executors hand the caller's context straight to the store, which applies the queryscope row filter. queryscope treats a missing scope as no restriction, so swapping in a fresh context would silently return every row in the deployment to any caller. Bounding. Oversized results are replaced wholesale, never tail-truncated: a truncated JSON document reads as complete to a model, which then answers from a fragment without hedging. An explicit 'narrow your filters' costs one round trip and gets a correct answer. Content. ContentHidden rows never yield content. That flag is the deployment's promise that a payload is not served back through any API, and a model is the last place it should resurface. Token counts come from the denormalized columns rather than the token_usage payload, since those survive object-storage offload and content-hidden rows. Unknown filter keys are rejected rather than ignored - a silently dropped filter answers a different question than the one asked, and nobody can tell. Scope limits, stated in the tool descriptions so the model does not discover them as empty results: group_by covers none and provider only, because the dimension histograms are not re-exported on LogManager and reaching around it to the store would lose the query scope. Virtual keys have rankings but no per-key time series, because ValidHistogramDimensions has no virtual_key entry. Guards nil message content when rendering a log row. ChatMessage.Content is a pointer and is routinely nil - a tool-call turn carries none, and an offloaded payload leaves the parsed history empty. This walks logged traffic, the least predictable data in the system, so every access is checked.

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR adds Odin read-only query tools, but the current production path does not make them available to users or enforce their result-size protection. Non-ASCII log content can also be corrupted during truncation, and one regression test is unreliable. Merge should wait for the production wiring and correctness/test fixes.

Return providers, or remove providers from the description.
The description says the tool lists models, providers, virtual keys and apps. The result map returns models, virtual_keys, apps and stop_reasons. Providers are missing, and stop_reasons is undocumented. The tool exists so the model stops guessing filter values, so a description that promises a value set the tool never returns causes the exact failure the tool prevents.
🐛 Proposed fix for the description mismatch
- description: "List the values that actually appear in this deployment's logs - models, providers, virtual keys, apps. " +
+ description: "List the values that actually appear in this deployment's logs - models, virtual keys, apps and stop reasons. " +
"Call this before filtering by a name you are not certain about. Guessing a model or key name returns an empty result that looks like a real answer.",If the log store exposes an available-providers query, add it to the result map instead and keep the current description.

Pin odinNow and assert unconditionally in this test.
Two problems exist in this test. First, the assertion sits inside if err != nil, so the test passes when no error is returned and proves nothing. Second, start_time is relative and resolves against the real clock through odinNow, while end_time is the fixed timestamp 2026-08-17T00:00:00Z. Once wall-clock time moves more than 47h past that timestamp, start_time lands after end_time, the error becomes start_time must be before end_time, and require.ErrorContains(err, "buckets") fails. Pin odinNow and use two absolute timestamps so the bucket check is the only reachable failure. The coding guidelines require deterministic tests.
💚 Proposed deterministic version
func TestOdinMetricsRejectsTooManyBuckets(t *testing.T) {
+ original := odinNow
+ odinNow = func() time.Time { return time.Date(2026, 8, 17, 0, 0, 0, 0, time.UTC) }
+ t.Cleanup(func() { odinNow = original })
+
_, err := runOdinTool(t, "query_metrics", &odinToolDeps{logManager: &fakeOdinLogManager{}}, map[string]any{
// A minute-scale bucket over a long window is what blows the count up.

})
- if err != nil {
- require.ErrorContains(t, err, "buckets")

}If the pinned 47h window does not exceed odinMaxHistogramBuckets for the bucket width calculateBucketSize returns, widen the window until it does.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Truncate on rune boundaries, not byte offsets.
text[:limit] cuts the string at a byte offset. Log content is arbitrary user text and is often non-ASCII, so this cut can split a multi-byte UTF-8 rune. The tool result then carries an invalid UTF-8 sequence, and the serialized JSON shows a replacement character instead of the original character. odinLogContentChars and odinDetailContentChars are described as character budgets, so a rune-based cut also matches the documented intent.

In `@transports/bifrost-http/handlers/odintools.go` around lines 277 - 282, Update
truncateOdinText to truncate by Unicode rune count rather than byte offsets,
while preserving the existing limit and suffix behavior. Convert or iterate over
text by runes and slice only at rune boundaries so odinLogContentChars and
odinDetailContentChars remain character-based budgets and output stays valid
UTF-8.
