Curates Databricks model labels through prefix-stripping aliasing and
materializes exact records for five endpoints missing from the
Databricks catalog.
**Alias-aware label resolution** (Databricks v2)
- Strip workspace-specific prefixes (`goose-`, `team-x-`, etc.) before
exact-record lookup so any prefixed alias resolves to its canonical
label without enumerating every alias variant.
- Return `None` for uncurated ids instead of falling back to a raw
string; callers control the fallback display.
**New exact records — label-only (Anthropic Messages route, axes from
family rules)**
- `databricks-claude-fable-5` → "Claude Fable 5" (materialized from
`anthropic-adaptive-xhigh-fable-5`)
- `databricks-claude-opus-4-8` → "Claude Opus 4.8" (materialized from
`anthropic-adaptive-xhigh-opus-4-8`)
- `databricks-claude-opus-5` → "Claude Opus 5" (materialized from
`anthropic-adaptive-xhigh-opus-5`)
- `databricks-claude-sonnet-5` → "Claude Sonnet 5" (materialized from
`anthropic-adaptive-xhigh-sonnet-5`)
**New capability-bearing record — Kimi K3 (MLflow Chat route)**
- `databricks-kimi-k3` → "Kimi K3" with axes from models.dev Moonshot
catalog: reasoning toggle + effort `[low, high, max]`, no default;
`_reconciliation_doc` records the source and reconciliation policy.
**Corpus and tests**
- 6 new normative-corpus vectors (canonical + one `goose-*` alias per
new id); executable vector count updated to 113 in both Rust and TS
gates.
- Rust and TS label tests extended to cover all 3 new canonical ids and
their aliases via the prefix stripper.
- Sentinel variable fix in discovery-provider test to prevent false
failure in Databricks dev environments where `BUZZ_AGENT_PROVIDER` is
set.

## Summary
Centralizes model capability knowledge — thinking mode, supported effort
levels, wire routes, and human-readable labels — into a single manifest,
`scripts/model-capabilities.json`. Rust and TypeScript each get a small
interpreter that reads the same manifest, replacing hand-maintained
tables scattered across both languages that had already drifted apart. A
capability change is now a data edit, not parallel edits to two code
paths. Supersedes the codegen approach explored in #3603.
A cross-language contract keeps the two interpreters honest:
`scripts/normative-corpus.json` is a golden snapshot generated from the
Rust resolver (103 vectors covering all six capability axes) and
replayed natively in TS. CI fails if either language disagrees with the
corpus or the corpus drifts from the resolver. Regenerate with `just
regen-model-corpus`.
## Behavior changes
- **Effort dropdown for `openai-compat` providers** no longer offers
`max`. The request path always clamped `max` to `xhigh` on the wire, so
the UI stops offering a value that was silently rewritten. UI-only,
wire-identical.
- **Databricks v2 routing (wire-visible):** uncurated endpoint names
carrying a bare Claude code-name segment (e.g. `goose-opus-5`) now route
to the MLflow chat wire instead of Anthropic Messages — they lose
Anthropic prompt caching but still succeed on a valid OpenAI-compatible
wire. Curated `databricks-claude-*` records and any name starting with
`claude` are unchanged. A handful of other uncurated/adversarial name
shapes similarly fall back to MLflow chat instead of pattern-matched
routes; every curated model resolves identically to before, all axes.
- **Curated model labels on the real discovery path.** The Databricks
API returns no display name, so discovery emits the raw endpoint id as
the model `name` (`{id, name: id}`) on every path. `ModelEntry.name` is
now curated at all four construction seams in `buzz-agent` — v2
discovery, v1 parse, the auth-empty default catalog, and the
configured-model fallback — via a read-only `databricks_registry_label`
lookup over the manifest's `databricks_v2` exact records; `id` stays the
raw wire/config value. A known id renders its curated label
(`databricks-gpt-5-5` → `GPT-5.5`), an unknown id passes through
unchanged, and the default-catalog row reads `GPT-5.5 (default
catalog)`. As a defense against older `buzz-agent` binaries and any
harness that echoes ids, `resolveModelLabel` treats a discovered name
equal to the trimmed id as absent and falls through to the registry
tier; a genuinely distinct name (including the suffixed default-catalog
label) still wins.
## Cleanup
Deletes the duplicated capability tables and their tests: the
`config.rs` gpt5 matchers, effort tables, and clamp logic; the legacy
segment-based Databricks v2 route classifier in `llm.rs`; and the TS
hand tables plus `effortTable.fixture.json`. All are replaced by
manifest lookups through the shared resolver — no line of capability
data exists in two places.
