Subject: [PATCH 03/38] fix(batch): track cost for managed batches with no
 attributable key/user/team

LiteLLM_ManagedObjectTable only stores created_by (user_id) and team_id,
never the raw API key hash. A batch created with the master key or a
team-less key has both null, so CheckBatchCost's synthetic logging_obj
for the completed batch carried no attributable key/user/team/end-user.
_should_track_cost_callback silently skipped the DB write in that case
(by design, to avoid tracking truly anonymous requests), with no error
or warning: batch_processed still became true, but no LiteLLM_SpendLogs
row was ever written despite real, already-incurred provider cost.

Extend the same allowance already made for unauthenticated pass-through
requests to aretrieve_batch's cost event, and pass job.team_id through
so a batch's team gets real attribution when one exists.

Subject: [PATCH 04/38] refactor(ui): drop unreferenced locals from dashboard
 route components

@typescript-eslint/no-unused-vars is disabled in the dashboard eslint
config, so unused locals accumulated with nothing to catch them. This is
the first slice: symbols under src/app that no code reads.

Every removal is an unused import, an unused interface or type alias, or a
local const whose only mention was its own declaration. Nothing else on the
touched lines changes, so no behavior moves with it.

Part of LIT-5162.

Subject: [PATCH 05/38] refactor(ui): delete the discarded expressions, not
 just their bindings

Dropping the binding but keeping the initializer left two statements that
compute a value and throw it away: a ternary in ChatUI returning rawSelected
from both branches under a comment about resolving server IDs, and an
isAdminRole call in the prompts panel that also kept its import alive.
Both computations were already unreachable in effect; remove them whole.

Subject: [PATCH 06/38] refactor(ui): drop unreferenced locals from shared
 dashboard components

Second slice of the same sweep, covering src/components. Same rule as the
first: every removal is an unused import, an unused interface or type alias,
or a local const whose only mention was its own declaration.

The modelGroupOptions computation in add_auto_router_tab goes whole rather
than losing only its binding, since a Set and two arrays allocated per render
and then discarded is no better than the dead const was.

ToolDetail is deliberately left alone. Its unread teamsData traces back to a
useQuery that still issues a /team/list request, so removing it drops a
network call; that is a behavior change and belongs in a slice that gets QA'd,
not this one.

Stacked on litellm_dead_locals_1_app_routes; review that one first.

Part of LIT-5162.

Subject: [PATCH 07/38] fix(pricing): sync flex/priority tier keys to dated
 OpenAI snapshot variants

Dated snapshots like o4-mini-2025-04-16 were missing the flex and priority cost keys their base alias carries, so service-tier requests against pinned snapshots were billed at standard rates. Sync the tier keys wherever the snapshot's anchor prices match the base alias, and add a drift regression test.

Subject: [PATCH 08/38] fix(cost): bill reasoning tokens at the service tier
 output rate

A tier request against a model that publishes tier output pricing but no
tier reasoning key (every current Gemini flash entry) billed reasoning
tokens at the standard output_cost_per_reasoning_token, undercounting
priority and fast traffic where thinking tokens dominate completions

generic_cost_per_token now resolves the reasoning rate with explicit
precedence: an explicit output_cost_per_reasoning_token_<tier> key wins,
then the tier-resolved output rate when the model prices that tier, then
the standard reasoning key, then the output base cost. The two tier
reasoning keys are wired through ModelInfo so providers can publish real
tiered reasoning prices when they exist

Subject: [PATCH 09/38] fix(guardrails): allow litellm_content_filter to run on
 post_mcp_call

ContentFilterGuardrail implements apply_guardrail, which is everything the
generic post_mcp_call_hook machinery needs to scan an MCP tool result before
it reaches the model, but post_mcp_call was missing from
get_supported_event_hooks. _validate_event_hook rejects any mode outside that
list, so a config with `mode: post_mcp_call` failed proxy startup with
"Event hook GuardrailEventHooks.post_mcp_call is not in the supported event
hooks" instead of scanning tool output.

Declaring the hook makes the indirect-prompt-injection case enforceable: an
MCP fetch tool returns a page whose body carries "IGNORE ALL PREVIOUS
INSTRUCTIONS ...", and the gateway blocks the result rather than handing it
to the model.

Subject: [PATCH 10/38] fix(guardrails): scan /v1/messages tool traffic

Guardrails silently skipped three surfaces on the Anthropic Messages
path, so an agent loop driven by /v1/messages ran unguarded:

- The Anthropic input translation never walked tool_result blocks, so
  content returned by a local tool (a curl, a file read, an MCP call)
  reached the model unscanned in both the string and list content
  shapes, images inside a tool_result included.
- tool_permission only understood ModelResponse, so an Anthropic
  non-streaming response or a raw SSE stream carrying tool_use blocks
  passed through with no rule ever evaluated.
- ContentFilterGuardrail scanned inputs["texts"] but never
  inputs["tool_calls"], so the arguments a model proposes for a tool
  call went unchecked.

Tool call arguments are parsed as JSON before filtering so a MASK
action rewrites the value and leaves the payload valid JSON; non-JSON
arguments fall back to scanning the raw string. Denied tool_use blocks
are dropped from the Anthropic content array and replaced with a text
block, and stop_reason resets to end_turn when nothing tool-shaped
survives.

Subject: [PATCH 11/38] fix(tool_permission): fail closed on unverifiable SSE
 streams and end the turn when every tool call is denied

An SSE stream that cannot be positively identified as Anthropic (no
parseable message_start event) now blocks instead of passing through
unscanned, closing the bypass where any raw-SSE backend skipped tool
permission checks entirely. Buffered chunks are joined back into one
stream before parsing, so events split across network chunk boundaries
assemble correctly instead of being silently dropped. Rewrite mode now
resets finish_reason to stop when no tool call survives, so the
re-encoded Anthropic stream reports stop_reason end_turn and clients do
not wait for a tool result that never comes

Subject: [PATCH 17/38] fix(ui): sync projects list page index to ?page= so
 back and reload keep the page (#36003)

* fix(ui): sync projects list page index to ?page= so back and reload keep the page

Paging the Projects list only moved TanStack's internal page index, so the URL
never changed: reload dropped you on page 1, browser Back left the page entirely,
and the page could not be shared.

The page index now comes from a nuqs ?page= query state with history: "push".
Pagination stays controlled off that value and the footer writes the URL
directly, because TanStack resets its page index whenever the data array
identity changes; letting it own the state would clear a deep-linked page as
soon as the projects query resolved. A page outside the current row set falls
back to page 1, which covers both a hand-typed ?page=99 and a search that
narrows the list below the current page.

* fix(ui): carry page_size in the url so restored history entries show the same rows

Greptile flagged that a history entry restoring ?page=N under a changed
local page size displays different projects than it originally showed.
Page size now rides the same query string via useQueryStates, size
changes reset the page inside a single history entry, and values outside
the offered options fall back to the default

Subject: [PATCH 19/38] fix(ui): opening a project now pushes ?project= so back
 and deep links work (#36001)

* fix(ui): drive project detail selection from the ?project= url param

Opening a project kept selectedProjectId in useState, so the URL never changed; the detail view could not be linked or reloaded and browser Back skipped past the Projects page entirely.

Selection now lives in the ?project= query param via nuqs with history: push, matching how Teams, Organizations and Virtual Keys already work.

* fix(ui): project detail close replaces history to match the other detail pages

Adopts the close semantics from PR #36013 so browser Back after an
in-page close leaves the Projects page instead of reopening the
dismissed detail; the close test now pins the replace mode

Subject: [PATCH 22/38] refactor(ui): drop unreferenced locals from tests and
 narrow destructures

Third and fourth slices of the sweep, combined because they raise nearly the
same question and neither changes what runs.

Nine test files plus one source file lose symbols whose only mention was
their own declaration. Ten more narrow a destructure to the keys actually
read, so `const { accessToken, userRole, userId: userID, premiumUser } =
useAuthorized()` keeps only `accessToken`. Aliases are preserved as written.

ignoreRestSiblings stays on so the omit idiom `const { tags, ...rest } =
metadata` is left alone; dropping `tags` there would fold it back into rest.

ToolDetail is held back again. Its unread binding only looks like a plain
deletion on the first pass, because the dead useMemo still reads it; one more
pass exposes a useQuery that issues a real request. That belongs with the
slices that get QA'd.

Part of LIT-5162.

Subject: [PATCH 23/38] refactor(ui): drop dead locals and unused React state
 across the dashboard

Removes declarations nothing reads, along with the writes that fed them, so
the remaining code says what it actually does.

Where a declaration was dead but its initializer had a real effect, the call
survives and only the binding goes: spies stay installed, renders still run,
and every awaited request keeps its await. Pure computations are deleted
whole rather than left as statements that build a value and throw it away.

Dead useState pairs are removed outright instead of being elided to
const [, setX], which would keep a hook and every write to a value nothing
reads. Three chains turned out to be dead end to end and are removed with
their fetches: the tool detail team list, the Teams MCP access group load,
and the user dashboard proxy settings load.

ColumnMeta's declaration merging in columnMeta.ts and view_logs/table.tsx is
a false positive; TypeScript requires those type parameters to match the
upstream signature exactly, so both get a scoped suppression instead.

Subject: [PATCH 24/38] fix(guardrails): keep tool-results-only scans off
 function definitions and merge scoped write-backs

Gate the OpenAI handler's tools forwarding behind scan_only_tool_results,
matching the Anthropic handler, so a tool-results-only scan can no longer
evaluate or rewrite trusted function definitions.

When a guardrail returns a replacement structured_messages list, substitute
the returned messages back into the positions their scoped originals came
from instead of installing the scoped list as the whole conversation, so
out-of-scope messages (system prompt, prior turns) survive redaction on
both the OpenAI and Anthropic paths.

Subject: [PATCH 31/38] fix(auto-router): accept every reminder marker pair a
 harness emits (#36029)

* fix(auto-router): accept every reminder marker pair a harness emits

reminder_markers held one (open, close) pair, so a harness that wraps
injected context differently per agent type only got the slice of traffic
using the configured envelope stripped. Every other agent type kept hitting
the original bug: its reminder-only turn never stripped to empty, won
"newest human ask", and the harness blob got classified in place of the
real question, choosing the tier and therefore the spend.

The field now takes a list of ReminderMarkerPair, following the
KeywordTierRule pattern already in this file so each pair validates itself
and errors point at reminder_markers.N.close rather than a bare index.

Blocks from different pairs can nest, which the gap construction could not
handle: resuming the kept text at an inner block's end walks back inside
the enclosing block and leaks its remainder. Running the block ends through
a maximum collapses nested and overlapping spans without a separate merge
pass, and stays linear in block count, which a fold over a growing tuple
of merged spans would not.

A single pair's ends already increase, so the maximum is the identity and
the default path is byte-identical: verified against the shipped function
over 200k generated inputs, and every existing reminder test passes
unchanged. The prior single-pair config shape is rejected loudly at
startup and at /model/new rather than silently stripping nothing.

* docs(auto-router): document reminder_markers in the complexity router README

* chore(ui): regenerate dashboard API types for the reminder_markers shape

 Reasoning markers in the system prompt do **not** trigger the reasoning override. This prevents system prompts like "Think step by step before answering" from forcing all requests to the reasoning tier.
 
+### Harness Reminder Blocks
+
+Agent harnesses inject their own context into the conversation as ordinary message text. That text is plumbing, not something a human asked for, so the router strips complete reminder blocks before classifying and picking a tier. A turn that is nothing but a reminder block strips to empty and is skipped, and the router falls back to the last real ask instead
+
+By default a block is anything between `<system-reminder>` and `</system-reminder>`. `reminder_markers` replaces that with your harness's own delimiters. Many harnesses use a different envelope per agent type, so list every pair you emit:
+
+```yaml
+model_list:
+  - model_name: smart-router
+    litellm_params:
+      model: auto_router/complexity_router
+      complexity_router_config:
+        reminder_markers:
+          - open: "<<<BEGIN_CONTEXT>>>"
+            close: "<<<END_CONTEXT>>>"
+          - open: "[[SUBAGENT_CONTEXT_BEGIN]]"
+            close: "[[SUBAGENT_CONTEXT_END]]"
+```
+
+Setting `reminder_markers` replaces the built-in `<system-reminder>` pair rather than adding to it, so list that pair too if your harness also emits it. Matching is case-insensitive. Blocks that nest or overlap across pairs are stripped whole. An unclosed delimiter is not a block and is left in place, which keeps prose that merely mentions a delimiter from being eaten

Subject: [PATCH 32/38] fix(router): return model and Bedrock batch fields in
 deployment credentials

get_deployment_credentials_with_provider dropped s3_region_name,
s3_encryption_key_id, and aws_batch_role_arn because
CredentialLiteLLMParams never declared them, and it never returned the
deployment's model, so proxy batch creation against Bedrock failed with
"LiteLLM doesn't support custom_llm_provider=bedrock for 'create_batch'"
or "AWS IAM role ARN is required" (#25104)

Provider-only file and batch calls keep their no-model contract:
get_team_provider_credentials strips the model key so a provider-scoped
request is not pinned to an arbitrary matching deployment

+    only started accruing that evening. Extending such a range to today's UTC bucket

+    is the future, and the future is empty. ``timezone_offset_minutes`` follows the
+    JS ``Date.getTimezoneOffset`` convention: UTC minus local, positive west of UTC.
+
+    The extension is strictly opt-in via ``include_current_utc_day`` so a consumer

Subject: [PATCH 34/38] fix: expired-miss share over all measured turns +
 cost-optimization tab labels (#36037)

* fix(ui): make the expired-miss stat row a focusable tooltip trigger

* fix: auto-router expired-miss percentage and cost-optimization tab labels

- change expired-miss percentage denominator from return-to-tier misses to
  all measured turns (same_model + first_visit + return_to_tier). when
  auto-routers flip tiers rapidly within TTL, return-to-tier turns become
  hits and disappear from the miss count; the old metric reported only the
  rare failure population. the new metric contextualizes that population as
  a share of overall coverage
- rename usage tab from 'Usage' to 'Overall'
- rename auto-router-usage tab from 'Auto-Router Usage' to 'Auto-Router'
- update component and unit tests to match new semantics

Subject: [PATCH 37/38] fix(guardrails): scan function-role results and dedupe
 returned tools

Under scan_only_tool_results, legacy OpenAI function-role messages now count as tool results, and duplicate names among guardrail-returned tools keep only the first occurrence. CustomGuardrail.structured_messages_cover_full_request lets CrowdStrike AIDR declare that its writeback already rebuilds the whole conversation, so handlers install it as-is instead of merging it into the full message list a second time and duplicating out-of-scope rows. Lint budget ceilings ratchet down to match the tree

Subject: [PATCH 38/38] fix(guardrails): refuse scan_only_tool_results combos
 that scan nothing

Prompt Security drops tool and function rows unless check_tool_results
is on, so it now reports scan-only support from that setting and the
registry refuses the pairing at boot. Pairing scan_only_tool_results
with skip_tool_message_in_guardrail excludes every message, so guardrail
initialization now rejects that combination too.
