## Screenshots / Proof of Fix
<!-- Include screenshots, screen recordings, or command (e.g., curl) + output demonstrating that your changes work as expected
The proof must be completely e2e with no mocks, using, for example, actual LLM calls costing real $. `pytest` commands are not enough
For bug fixes: show reproduction before the fix and passing behavior after
Include the commit hash each proof was captured at, for both the before and the after runs
If the change applies to all three LLM endpoints (/v1/responses, /v1/chat/completions, /v1/messages), include proof for every single one of them, not just one
For new features: show the feature working end-to-end
For UI changes: include before/after screenshots -->
The proof must be completely e2e with no mocks, using actual LLM calls costing real $$$ if applicable. `pytest` commands are not enough
Show ONLY the latest run: capture Before at the merge base and After at the PR's current tip, and when new commits change behavior, replace this whole section with the fresh run instead of stacking it on top of older ones. The run must be up to date. As soon as a new commit is made and it makes this PR description's after sha stale (it's no longer tip of PR), you must re-run the QA
Structure the section exactly as below: Before and After one heading level below this section, each naming the commit hash it was captured at, one lower-level heading per case inside each, the same case names in the same order on both sides, and numbered steps (command, observed output) under every case, never loose prose; shared setup (config, payloads) goes above Before, and with a single case, drop the case headings and number the steps directly
### Before (<hash>)
#### <case 1>
1. ...
2. ...
#### <case 2>
1. ...
### After (<hash>)
#### <case 1>
1. ...
2. ...
#### <case 2>
1. ...
For bug fixes: Before shows the reproduction, After shows the same steps passing
For new features: Before shows the capability missing, After shows it working end-to-end
If the change applies to all three LLM endpoints (/v1/responses, /v1/chat/completions, /v1/messages), make each endpoint its own case, not just one
For UI changes: before/after screenshots under the same headings -->

@ -53,6 +53,8 @@ When you fix violations gated by `ruff-strict-budget.json`, `type-discipline-bud
`make check` (f.k.a. `make pre-commit`, which still works identically as an alias) saves its complete output to a log file in .git (overwriting previous logs) and prints that path as its first and last output lines. To inspect a run, read or grep that log instead of re-running the multi-minute checks just to see a different slice
`make check`, `make lint`, `scripts/pre_commit_lint.sh`, and the standalone budget gates (`scripts/ruff_strict_gate.py`, `scripts/type_discipline_gate.py`, `scripts/type_check_gate.py`) each hold one of 2 machine-wide slots, so when other sessions or worktrees on the same box are already running heavy work, yours prints "all N machine-wide slots are busy; queueing" and then stays quiet until a slot frees. Give the command a long timeout and let it wait rather than killing it, retrying it, or assuming it hung. Don't change the # of machine-wide slots or make it unlimited by setting `LITELLM_GATE_SLOTS=0`
If you're trying to create a new function that relies on untyped stuff, instead of adding more Any's and pushing `reportAny` / `reportExplicitAny` closer to their basedpyright ceilings, 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
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()` / `MappingProxyType()` / `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
@ -83,7 +85,8 @@ Follow these coding conventions for new/updated code (a three-line fix in a lega
- Never-nester: early returns over deep nesting
- Don't throw; model failures as values (One function (e.g., raise_public) maps error union to existing public exception contracts via exhaustive match + assert_never)
- No mutation; don't reassign variables, global or local. Instead of mutable lists and dicts, prefer tuples, frozen dataclasses (with slots=True), `MappingProxyType`, etc.
- Annotate every variable with `: Final` (LIT010). Unpacking and walrus targets cannot carry the annotation, so they are implicitly final. Don't rebind them. Never rebind or mutate function parameters (LIT011); `self`/`cls` attribute stores are the exception. If rebinding or in-place mutation is truly unavoidable, suppress with `# rebind-ok: <reason>` explaining why

- Qualify every TypedDict field with `ReadOnly[...]` (LIT012), which nests freely with `Required` / `NotRequired` / `Annotated` in any order. If making the key writable is truly unavoidable, suppress with `# writable-ok: <reason>`
- Use dependency injection
- Fully typed; no `Any` or coarse types like `dict[str, Any]` or just `dict`. Every function parameter must be strongly typed
- Use tagged unions + match

skips incrementing the key/team budget counters, losing the parent's spend.
``user_api_key_auth`` itself is kept, sanitized, because model access-group filtering

Calculate cost for a given number of tokens based on a true tiered pricing structure.
This function iterates through sorted pricing tiers, calculates the cost for the
number of tokens that fall into each tier's range, and sums them up to get the total cost.
Args:
tokens (int): The total number of tokens to calculate the cost for.
tiered_pricing (List[dict]): A list of dictionaries, where each dictionary
represents a pricing tier.
cost_key (str): The key in the tier dictionary that holds the per-token cost
(e.g., 'input_cost_per_token').
fallback_cost_key (Optional[str], optional): A fallback key to use if the
primary `cost_key` is not found in a tier. Defaults to None.
Returns:
float: The total calculated cost for the given tokens.
Example:
>>> tiered_pricing = [
... {"range": [0, 100000], "input_cost_per_token": 0.0001},
... {"range": [100000, 500000], "input_cost_per_token": 0.00005},

Move image content out of role:"tool" messages into a user message inserted
after the run of consecutive tool messages it belongs to.
The OpenAI chat spec only allows text in tool messages, so OpenAI-compatible
providers either reject or silently ignore images placed there (e.g. an
Anthropic tool_result carrying a screenshot). Each rewritten tool message
keeps its tool_call_id and any non-image parts (falling back to a text
placeholder), and the user message is only inserted after the last
consecutive tool message so the assistant tool_calls -> tool messages
adjacency that strict providers validate is preserved. The inserted user
message leads with a text part marking the images as tool output so the
model does not read them with user authority.
