* perf(lint): skip and cache base gate passes, parallelize make lint, skip redundant prisma generate
make pre-commit paid for a full second basedpyright pass over a merge-base
worktree on every run even when no rule was over its ceiling, re-generated an
unchanged Prisma client, and ran seven independent checks sequentially. The
basedpyright and ruff strict gates now skip the base pass when head is within
every limit (the same early-out type_discipline_gate already had), the
basedpyright base counts are cached under the git common dir keyed by
merge-base commit, pyrightconfig.json, and uv.lock, prisma generate only runs
when the schema or prisma version changed, and make lint fans its checks out
through a parallel sub-make after a single setup phase
* fix(lint): keep the base-cache scratch file out of the prune glob
The tmp+rename scratch in store_counts was named basedpyright-base-<hash>.json.tmp,
which the stale-entry prune glob (basedpyright-base-*) also matches, so a concurrent
lint run from another worktree sharing the same git common dir could unlink it between
write_text and replace and crash the gate with FileNotFoundError. The scratch is now
dot-prefixed so the glob can never see it, pid-suffixed so concurrent writers of the
same entry never share a scratch, and the prune glob is restricted to committed
*.json entries
* chore(lint): raise basedpyright per-rule slack to 50% of baseline
The per-rule ceilings in basedpyright-code-budget.json sat at roughly 10% slack over baseline, which several in-flight PRs are already bumping into. Raise the slack on every rule to at least 50% of its baseline so there is ample headroom for a long while, while never lowering any rule that already had more generous slack (e.g. reportReturnType stays at 100).

* refactor(lint): collapse type/lint budgets to a single per-rule limit
The three non-frontend budget files (ruff-strict, type-discipline, basedpyright-code) tracked a per-rule baseline and slack whose sum was the ceiling. Nothing consumed the split beyond that sum, so this replaces both keys with a single limit equal to the old baseline + slack; the original baselines live in git history if anyone needs them.
The gate scripts and the ratchet guard now read limit directly. lint-budget-update no longer re-captures raw counts; it ratchets each rule's limit down by the number of violations this branch cleared since its branch point (the merge-base), so the granted headroom shrinks by exactly what was fixed and a limit never rises. The ratchet guard reads either schema so it still compares correctly across the migration boundary.

* chore(lint): surface staged-vs-working parity for pre-commit and budget-update
make pre-commit selects which checks to run from the staged index but runs the linters over the working tree, so unstaged edits to tracked files and untracked files skew a green/red away from what a commit of only the staged changes would produce. There is no safe in-place way to lint the index, so the script now warns when unstaged or untracked changes are present, and CLAUDE.md documents that you must stage everything first for both make pre-commit and make lint-budget-update to predict CI correctly.

Introduce a single, typed caller identity that is resolved once at the auth
boundary and read by reference downstream, instead of being re-derived from a
50-field key object or rebuilt from request metadata.
What this adds (litellm/proxy/auth/resolvers/), organized by responsibility:
- Principal: a small, frozen, identity-only value type (user / organization /
teams / project / end-user / roles / scopes / network), with its sub-models
and the role mapping. No budget or policy state; those stay on the key object.
- DbIdentityStore: the auth flow's resolver, owning both halves of resolving a
caller. resolve_key does the one combined_view lookup (cache, then DB via the
shared lower-level helpers, then write-back) and returns the key object, which
still flows for budget / rate-limit / policy unchanged. principal_from_key
projects the identity slice of that key object into a Principal, issuing no
lookup. user_api_key_auth resolves every key through the store rather than
calling get_key_object directly; auth_checks.get_key_object stays as the legacy
entrypoint for its other callers until they migrate.
- network: the X-Forwarded-For / trusted-proxy CIDR primitives live here in one
place. trusted_proxy_utils now imports them rather than keeping a second copy.
At the seam, user_api_key_auth projects one per-request Principal off the
resolved key object and stamps the request network context onto it once
(X-Forwarded-For is trusted only when trusted_proxy_ranges is configured). It is
attached to request.state.principal for the downstream consumers later phases
add. The projection is additive and defensive: a failure never rejects an
already-authenticated request, and a missing principal must be treated as deny
by any future reader. The Principal is always identifiable (credential_ref and a
stable subject off the token), never anonymous.
This is additive and changes no behavior today; it is the identity foundation
the spend-attribution and authorization phases build on.
* feat: add CI-parity mode and truncation-proof summary to strict ruff gate
* refactor: tolerant worktree cleanup and concrete GateInputs types
* fix: clean up temp dir when git worktree add fails
* fix: align lint-gate with CI by dropping unused --ci-parity path
The lint-gate Makefile target invoked ruff_strict_gate.py with --ci-parity,
which counted violations on a throwaway merge of base into HEAD against base
counts at the base tip. CI in test-linting.yml runs the same script without
--ci-parity on a PR-head checkout, taking the gather_fast path that counts on
the live tree against base counts at the merge-base. A local pass could
therefore disagree with CI.
Drop --ci-parity from the Makefile and remove the now-unused gather_ci_parity
branch and flag so there is one code path that both local and CI exercise.
The docstring claim that CI runs against the synthetic merge ref was also
wrong; the workflow checks out github.event.pull_request.head.sha.

* feat: add ruff strict-rule suppressions baseline gate
Introduce a stricter ruff rule set (typed params, no Any, complexity and
arg-count caps, mutable-default and global-rebinding checks) grandfathered
against the current tree and enforced as a budget rather than zero-tolerance
ruff-strict.toml defines the 9 rules separately from ruff.toml so the existing
ruff check stays green. scripts/ruff_suppressions.py builds the per-file,
per-rule baseline in ruff-suppressions.json and gates CI by failing when the
total grows past the baseline plus a 0.5% slack margin. The baseline ratchets
down via `make lint-suppressions-update` after fixes
* fix: surface per-file drift as a warning on a passing suppressions check
Greptile flagged that cmd_check computed per-file regressions but only printed
them on failure, so violations shifted between files (or a brand-new file under
the slack) passed with a silent OK. Print them as a non-fatal warning on the
pass path too; pass/fail behavior is unchanged
* refactor: gate strict ruff rules on the delta vs base, not a frozen baseline
The committed total-count baseline went stale against a moving base. CI lints the
PR merged with the current staging tip, so violations merged by other PRs counted
against this PR and tripped the budget even though nothing here touched them
Replace it with a drift-proof gate. scripts/ruff_strict_gate.py runs ruff on the
head, keeps only violations on lines this change adds relative to the merge-base,
and fails when a rule exceeds its per-rule allowance in ruff-strict-budget.json
(all 0 today). Because the base is measured live, base drift cancels out and only
what the change introduces is gated. Drops ruff-suppressions.json and the old
suppressions script
* chore: allow 5 new ANN001/ANN003/ANN401 per change
Give the three annotation-completeness rules a small per-change allowance so a
large new module is not blocked over a few untyped params or kwargs, while the
correctness and structural rules (B006, C901, PLR0913, PLW0603, RUF012, ANN002)
stay at 0
* feat: add TID251 typing.Any/Dict import ban and widen annotation budgets
Add TID251 (flake8-tidy-imports banned-api) to ruff-strict.toml, banning new
imports of typing.Any and typing.Dict and steering new code toward structured
types. It counts the import site, about one per file, so it is set non-blocking
at 50 as a forward-looking signal
Widen the annotation-completeness budgets so they nudge rather than block:
ANN001 50, ANN401 50, ANN003 25. Correctness and structural rules stay at 0
* refactor: make the strict gate a drift-safe per-rule total ceiling
Switch the gate from a per-change allowance to a hard ceiling on each rule's
total count across the codebase. The ceiling is baseline + slack in
ruff-strict-budget.json, with baseline captured from today's tree
To stay drift-safe, the gate counts each rule on the head and on the merge-base
(via a throwaway git worktree) and fails a rule only when its head total is over
the ceiling and higher than the base, so base drift never blames a change that
did not add to that rule. Annotation rules keep generous slack (ANN001 and
ANN401 50, ANN003 25, TID251 50); structural and correctness rules are frozen at
today's count. Add make lint-strict-budget-update to re-capture baselines
* chore: give the structural strict rules a cushion of 3
To be liberal to start, B006, C901, PLR0913, PLW0603, RUF012, and ANN002 each get
a slack of 3 instead of 0, so an occasional legitimate case is not hard-blocked.
The annotation budgets are unchanged, and these ratchet down later
* feat: ban more typing collection aliases and tighten annotation slack to 10
Add typing.List, typing.Set, typing.MutableSequence, and typing.MutableMapping to
the TID251 banned-api list, steering new code toward tuple, Sequence, Mapping,
frozenset, and frozen dataclasses. This raises TID251's baseline to 2404
Bring the three rules that were at slack 50 (ANN001, ANN401, TID251) down to 10
* docs: document the strict-gate ratchet and Any-avoidance in CLAUDE.md
Add a line on running make lint-strict-budget-update to knock baselines down
after fixes, and a line on validating untyped inputs in the caller rather than
spending the Any budget
* feat: make it a bit more strict
