-When you fix violations gated by `ruff-strict-budget.json`, `mypy-code-budget.json`, or `basedpyright-code-budget.json`, run `make lint-budget-update` and commit the lowered baselines so the ceilings ratchet down instead of leaving stale headroom
+When you fix violations gated by `ruff-strict-budget.json`, `mypy-code-budget.json`, `basedpyright-code-budget.json`, or `any-discipline-budget.json`, run `make lint-budget-update` and commit the lowered baselines so the ceilings ratchet down instead of leaving stale headroom
 
 If you're trying to create a new function that relies on untyped stuff, instead of adding more Any's and bringing it closer to the max, just validate it in the caller with Pydantic (a model or `TypeAdapter` that returns the typed thing or raises will do) and then pass the now typed variable in
 
-The Any-discipline gate (`make lint-any`, also a CI job) fails when a line you changed under `litellm/` holds a value typed `Any`, including the `X | Any`. Ideally `# any-ok: <reason>` is never used; treat it as a last resort for a genuine typed/untyped boundary that Pydantic truly can't model
+The Any-discipline gate (`make lint-any`, also a CI job) fails when a changed file under `litellm/` carries more `Any`-typed values than its grandfathered ceiling in `any-discipline-budget.json` (each file's captured count plus 50% headroom). It flags values whose inferred type *contains* `Any`, including the `X | Any` unions mypy/basedpyright accept. Editing a legacy file is fine as long as you don't push its `Any` count past the ceiling; a brand-new file must be `Any`-free. Fix a value by giving it a concrete type (if you're given untyped input, validate with Pydantic). Ideally `# any-ok: <reason>` is never used; treat it as a last resort for a genuine typed/untyped boundary that Pydantic truly can't model
 
 If you get an LIT001 or LIT002 fail, refactor the code to follow functional programming best practices rather than introducing mutable data structures. For example, build values in one shot with comprehensions or generators wrapped in `tuple()` / `frozenset()` instead of seeding an empty `list`/`dict`/`set` and mutating it over time. Ideally `# mutable-ok` is never used; reach for it only as a genuine last resort when an immutable rewrite is truly impossible, and always pair it with a real reason

-    The database stores dates in UTC. When a user in a different timezone
-    selects a local date range, we need to expand the UTC query range to
-    capture all records that fall within their local date range.
+    The aggregation table (e.g. LiteLLM_DailyUserSpend) stores spend in whole-UTC-day
+    buckets keyed on date as YYYY-MM-DD. Any conversion from a local date range to a
+    UTC date range using only date arithmetic must round to whole UTC days, allowing up
+    to 24h of slop at each boundary. The previous implementation expanded the SQL range
+    by an extra full UTC day on whichever side the offset pointed, which pulled in 24h
+    of unrelated bucket data per boundary and produced approximately 100% over-counting
+    on single-day queries (e.g. IST May 29 returning UTC May 28 + UTC May 29 in full).
+    Sums of single-day queries then exceeded the equivalent multi-day aggregate, which

-        timezone_offset_minutes: Minutes behind UTC (positive = west of UTC)
-            This matches JavaScript's Date.getTimezoneOffset() convention.
-            For example: PST = +480 (8 hours * 60 = 480 minutes behind UTC)
-

-        Tuple of (adjusted_start_date, adjusted_end_date) in YYYY-MM-DD format
+    Treating the local date as the UTC date trades a small one-time boundary slop for
+    correct, monotonic, additive results across single-day and multi-day queries. A

+Scope: changed files, per-file budget
+-------------------------------------
+litellm carries a large amount of pre-existing `Any` (a single legacy file can
+have >100 findings). Rather than force every touched line clean (the original
+changed-lines rule, which tripped on merely *editing* a legacy `X | Any` line),
+this gate grandfathers each file: `any-discipline-budget.json` records every
+file's current count of Any-typed values, and a file fails only when its count
+exceeds `baseline + slack`, where `slack` is 50% headroom (rounded up). New or
+unbudgeted files have baseline 0, so they stay airtight.
+
+Only *changed* files (vs the merge-base with `--base`) are re-type-checked -- an
+unchanged file's count can't move from edits this branch didn't make -- so the
+per-PR cost equals re-checking just those files, exactly like the original
+changed-lines gate. The whole-tree scan needed to (re)capture the budget
+(~2 min, ~3 GB) runs only under `--update`.
+
+The budget is a one-way ratchet (the same `{baseline, slack}` shape as the
+ruff / mypy / basedpyright budgets) guarded by `scripts/budget_ratchet_check.py`:
+a file's ceiling may fall but never rise. Drive a file's count down and rerun
+`--update` (`make lint-any-budget-update`) to lock in the lower ceiling.

+Integration / regression tests for Anthropic tool-search (`tool_reference`)
+content blocks on the cost-calculation and streaming-assembly paths used by
+Claude Code.
+
+Claude Code's tool-search feature emits assistant content blocks of the form
+``{"type": "tool_reference", "tool_name": ...}`` -- a lightweight pointer to a
+deferred tool. Before the fix, `token_counter` did not recognise this block
+type and raised ``Invalid content item type: tool_reference``.
+
+Why this matters (the bug these tests guard against):
+
+  * On the cost path, that exception propagates out of ``completion_cost`` ->
+    ``response_cost_calculator``. The proxy logging layer catches it and nulls
+    ``response_cost``; the spend-tracking callback then skips the request, so
+    the entire SpendLogs row is dropped. The request succeeds for the caller
+    but the spend is silently never recorded -- a cost undercount on ALL
+    tool-search traffic.
+
+  * On the streaming-assembly path, ``stream_chunk_builder`` recomputes the
+    prompt tokens from the request messages when the provider stream does not
+    carry usage. The same exception there was swallowed and prompt tokens
+    silently collapsed to 0 -- a quieter undercount of the same traffic.
+
+These tests exercise the real public entry points (not the private
+``_count_content_list`` helper) so the whole chain is covered end to end.

+Validate that the native (first-party) Anthropic Claude Sonnet 4.5 / 4.6 entries
+carry the 1-hour prompt-cache write tier (`cache_creation_input_token_cost_above_1hr`)
+in `model_prices_and_context_window.json`.
+
+Anthropic's first-party API charges a separate 1-hour cache write rate (2x base
+input) alongside the 5-minute write (1.25x base input) and cache read (0.1x base
+input). The 1h/5m ratio is therefore 1.6. Without the 1-hour field, cost tracking
+on 1-hour-TTL prompt caching falls back to the 5-minute rate and undercounts spend.
+
+The native (non-bedrock) `claude-sonnet-4-5*` / `claude-sonnet-4-6` entries were
+missing this field, while every sibling (`vertex_ai/`, `azure_ai/`, the
+`*.anthropic.*` Bedrock profiles) and the older `claude-sonnet-4-20250514` already
+carried it. This test guards against regression.
