Subject: [PATCH 01/16] test(cost_calculator): point image-generation
 deployment price test at a live gemini row (#42615)

The test priced gemini/gemini-3.1-flash-image-preview, which #42435 removed
from the cost map as deprecated, so the calculator had no per-token rates to
keep and the hardcoded expected value no longer matched. Price the live
gemini/gemini-3.1-flash-image row instead and derive the expected cost from
that row in litellm.model_cost, so a rate change on it cannot break the test
while a calculator that drops the map's token rates still fails it.

Subject: [PATCH 02/16] test(utils): accept the per-size image cost keys in the
 price-map schema check (#42612)

The cost map's fal_ai/fal-ai/trellis-2 entry prices its output by resolution
with output_cost_per_image_512, output_cost_per_image_1024, and
output_cost_per_image_1536, which litellm/types/utils.py types and the fal_ai
cost calculator reads, but INTENDED_SCHEMA in
test_aaamodel_prices_and_context_window_json_is_valid never allowed them, so
the test fails on main with "Additional properties are not allowed". Add the
three keys next to output_cost_per_image in the schema and in the cost-under-1
field list so a per-size image price is validated like the per-size video ones

Subject: [PATCH 03/16] fix(ollama): send PNG and JPEG images without requiring
 Pillow. (#41979)

* fix(ollama): send PNG and JPEG images without requiring Pillow

The ollama/ completion transport imported Pillow before it looked at the image, so every image request failed with a 500 on installs without Pillow. That includes the Docker image, where Pillow is only a CI dependency

Detect PNG and JPEG from their leading bytes and pass them through untouched. Pillow is now imported only when another format has to be re-encoded as JPEG, and that case still raises the same install hint

* fix(ollama): address Greptile findings on image conversion

Catch all exceptions on Pillow import, not just ImportError, so the helpful
install hint always appears. Break a line that exceeded 120 characters

From: yuneng-jiang <yuneng@berri.ai>

Subject: [PATCH 05/16] test: point CircleCI-only suites at models still in the
 cost map (#42617)

* test: point CircleCI-only suites at models still in the cost map

#42435 removed cost map entries past their deprecation date and #42437 added
litellm_uisettings to the config-synced tables, but both only updated
tests/test_litellm. The CircleCI-only suites (local_testing, llm_translation,
logging_callback_tests, litellm_utils_tests, unit) kept using the removed
models or the old table list and went red on main.

Each test keeps its assertions and swaps the removed model for a current one
with the same provider and capabilities. The fireworks tests pick a vision
model from the cost map because #34941 set supports_vision false on
minimax-m3, and the vertex image provider test injects the image model set
because #42435 removed every vertex_ai-image-models entry.

* test(vertex_ai): register the image model through add_known_models in the provider test

Subject: [PATCH 07/16] fix(s3): replace colons in generated log filenames
 (#40452)

* fix(s3): replace colons in generated log filenames

Bedrock and Vertex AI batch file uploads use s3:// and gs:// URIs as
response ids. The shared filename sanitizer replaced slashes but kept
the scheme colon, producing log object keys that Hadoop-style consumers
reject as a relative path in an absolute URI.

Fixes #40234

* test(s3): drop docstrings flagged by review

Subject: [PATCH 08/16] test(realtime): drop legacy InvalidStatusCode tests and
 pin websockets imports (#42624)

The two redaction tests raised the deprecated InvalidStatusCode, which the
websockets 15 asyncio client never raises, and asserted the raw 403 close
code that the handshake refusal path replaced with 1008. The refusal path
builds its close reason from the status code alone, so there is no secret
to redact there, and the handshake refusal tests already cover the error
event and the 1008 close.

Those refusal tests only passed when run after a sibling test had imported
websockets.asyncio.client, since websockets lazy-loads its exceptions
submodule. Importing InvalidStatus, Response, and Headers from their own
submodules makes them pass in any order.

Subject: [PATCH 10/16] ci(test-unit): drop dead misc shard paths and skip
 missing paths with a warning (#42603)

Eight directories the misc shard named moved to tests/unit on 2026-09-20, and one
missing path makes pytest-xdist collect [0 items] for the whole shard, which the
exit-5 tolerance turned into a green required check running nothing. The shared
Run tests step now drops a path that does not exist with a ::warning:: and runs
pytest over the rest, keeping option tokens verbatim.

Subject: [PATCH 11/16] fix(proxy): keep the in-flight daily spend batch when
 shutdown cancels the flush (#42593)

* fix(proxy): keep the in-flight daily spend batch when shutdown cancels the flush

A daily spend batch drained from the in-memory queue was dropped for good when
the scheduler tick was cancelled by shutdown, because asyncio.CancelledError
bypasses the except Exception requeue. The flush now requeues the drained rows
on cancellation and re-raises, and each daily batch upsert runs in an
interactive transaction so a statement that already reached Postgres is rolled
back with the cancel instead of committing behind the requeue

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(proxy): requeue the cancelled daily spend batch before its rollback returns

Behind a lock the rollback of the cancelled interactive transaction only
returns once the blocked statement does, which is after the shutdown flush
has already run. The commit now runs as a shielded task so the cancelled
tick requeues the batch at once and lets the rollback finish in the
background. The final flush then finds the rows and writes them exactly once

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(proxy): give the recording db a transaction seam for the bulk upsert tests

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(proxy): route the mocked daily tag spend upsert through the transaction seam

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(proxy): restore the drained Redis tag batch when shutdown cancels its commit

Subject: [PATCH 12/16] fix(utils): isolate callback errors in
 async_post_call_success_deployment_hook (#42535)

* fix(utils): isolate callback errors in async_post_call_success_deployment_hook

A callback that raises inside async_post_call_success_deployment_hook no longer
fails the completed request. The exception is logged with the callback class and
call_type, the response stays as it was, and later callbacks still run. Guardrail
callbacks are exempt because raising is how a post-call guardrail blocks

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(utils): drop unrelated ruff autofixes from test_utils

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(utils): drop fastapi import from guardrail propagation regression

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(utils): cover every success deployment hook call type with a raising hook

Parametrize the unit regression over video, embedding, responses, image, rerank,
transcription, chat and anthropic messages responses and assert the failure log
names the callback and call type. Run the integration test through a real proxy
for /v1/chat/completions, /v1/embeddings, /v1/responses and /v1/videos

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(integration): move raising success hook cases into the existing callback delivery file

Subject: [PATCH 13/16] test(e2e): add secret manager lanes for HashiCorp Vault
 and CyberArk Conjur (#42503)

* test(e2e): add a HashiCorp Vault secret manager lane

key_management_system had no end-to-end coverage: the Rust crates and the
Python unit tests all run against mocked managers. This adds a secret_manager
suite that drives a proxy configured with hashicorp_vault against a real Vault.

The tests seed a fresh secret name per test with the runner's OPENAI_API_KEY and
register a deployment pointing at os.environ/<name>. The proxy's env never holds
that name, so get_secret's os.environ fallback cannot mask a broken manager, and
a bogus value in Vault must come back as the provider's 401. Virtual keys are
checked written to and removed from Vault under prefix_for_stored_virtual_keys.

The setting is global to the proxy, so the lane has its own config and the
secret_manager_vault opt-in marker, and stays out of the per-PR selector.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* test(e2e): make the secret manager suite backend-agnostic

One marker and opt-in (secret_manager / E2E_SECRET_MANAGER=<system>) pick the
backend from secret_backends.BACKENDS. The tests reach the manager through a
SecretStore protocol, and each backend contributes a secret_store_<system>.py
module, a registry entry, and gateway/secret_manager_<system>_ci_config.yml.
requires_capability deselects tests a backend cannot support (CyberArk does
not delete), and test_secret_backends.py checks every lane config against its
backend without a live stack.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* test(e2e): add a CyberArk Conjur secret manager lane

Adds cyberark as the second secret_manager backend: a Conjur store over its
REST API (policy-declared variables, raw-text values, policy-patch teardown),
its lane config, and a registry entry without deletes_stored_keys, since the
proxy's CyberArk delete answers not_supported and Conjur keeps the key.

secret_manager/backend.sh up|down <system> boots any backend in Docker and
writes proxy.env and tests.env, so every lane runs the same way; the registry
test checks the script boots exactly the registered backends. e2e_http gains
send_text_external for APIs that speak raw text rather than JSON.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(e2e): give the secret manager suite a client with .proxy and address review

The shared resources fixture reads client.proxy, so a bare ProxyClient errored every
live test at setup. backend.sh now writes its env under a per-user directory with
umask 077, the markerless unit tests are gone per tests/e2e/AGENTS.md, and routine
comments are trimmed.

 - `router/` - routing and reliability behavior (fallbacks, cooldowns) plus the memory tests (`test_reliability_memory_e2e.py`: every worker's RSS as read at collection time, before any test traffic, must sit under a fixed idle budget, the release-gate check for a DB-backed boot that idles near the pod limit the way v1.100.x did; and a few hundred failing requests with retries and fallbacks must not grow proxy RSS past a fixed budget nor store a request snapshot past a fixed size, the release-gate check for the v1.100.0 retry-breadcrumb leak)
 - `load/` - performance-category tests, kept OUT of the main suite: throughput/load SLO tests are a different testing category from functional e2e (variance-driven, historically flaky) and live outside this suite until re-implemented as their own pipeline (LIT-5163); do not add a live load test that runs in the default collection. What lives here: the weekly session-anomaly test (`test_weekly_session_anomaly_e2e.py`, Claude Code-shaped multi-turn sessions against real providers with ceilings on error rate, cache read/write, turn time, and spend; marked `weekly` and deselected unless `E2E_WEEKLY_ANOMALY` is set, driven by `.github/workflows/weekly_load_anomaly.yml`), the Redis chaos test (`test_redis_chaos_e2e.py`, locust load against mock deployments split round robin over `/chat/completions` and `/v1/messages`, one endpoint per simulated user, with `CLIENT PAUSE ALL` on the proxy's Redis mid-run to simulate it being down outright, asserting zero failed requests on every endpoint, budgeting RSS and CPU-per-request as ratios against the same run's healthy phase, and holding p50/p90/p99 latency and log-bytes-per-request to flat ceilings (a ratio cannot bound those two: an open breaker skips Redis instead of waiting on it, so the chaos phase can measure cheaper than baseline while still being far slower than a user should see); needs a proxy booted from `gateway/redis_chaos_ci_config.yml` on the same host with `E2E_PROXY_PID` and `E2E_PROXY_LOG` set, marked `redis_chaos`, deselected unless `E2E_REDIS_CHAOS` is set and excluded from the per-PR selector like the rest of `load/`, driven by `.github/workflows/test-e2e-redis-chaos.yml` and by the Buildkite `e2e-redis-chaos` step in project-releaser, which runs the proxy, Postgres and Valkey co-located with pytest in one pod and sets the opt-in), and markerless harness unit tests for the locust, process-usage, and session-anomaly aggregation logic
 - `other/` - the holding-pen suite for the `other.*` registry cluster with no home of its own yet: the master-key auth gate, JWT auth (access tokens issued by a real Keycloak realm, `idp.py` plus `idp_realm.json`, whose JWKS the proxy's `JWT_PUBLIC_KEY_URL` points at; see CONTRIBUTING.md for the start command and config block), and the process-lifecycle health probes (liveness, public readiness, authenticated readiness diagnostics). Promote a cluster out once it is large/stable enough for its own suite
+- `secret_manager/` - the gateway's `key_management_system` against a real secret manager: deployment keys resolved from it (`os.environ/<name>` where the name exists only in the manager) and virtual keys written to and deleted from it. The tests are backend-agnostic and each backend is its own lane, because the setting is global to the proxy: `E2E_SECRET_MANAGER=<system>` opts in and picks the backend from `secret_backends.BACKENDS`, the proxy is booted from `gateway/secret_manager_<system>_ci_config.yml` against the live manager, and the tests reach that manager through the backend's `SecretStore` (`secret_store_<system>.py`). A test needing something not every backend does carries `requires_capability(...)` and is deselected on lanes that lack it. `secret_manager/backend.sh up <system>` runs a backend in Docker and writes the proxy's and the tests' env. Marked `secret_manager`, deselected unless `E2E_SECRET_MANAGER` is set, and kept out of the per-PR selector. Backends today: `hashicorp_vault` and `cyberark` (CyberArk Conjur, which cannot delete, so the delete test is Vault-only)
 - `gateway/` - proxy configuration only (`litellm-config.yml`); no tests
 - `claude_code/` - the Claude Code compatibility matrix: drives the real `claude` CLI (and HTTP probes) against a proxy for each feature x provider cell, reporting tagged-union outcomes via the `compat_result` fixture; ships its own driver/builder/publisher plus `_*_unit_tests/` trees. The HTTP probes ride the shared transport (`ProxyClient.count_tokens` / `ProxyClient.messages`); the CLI-driving path stays bespoke
 - `ui/` - the Admin UI browser suite: Playwright in TypeScript, driving the dashboard served by a live proxy on port 4000 (seeded postgres + mock LLM upstream; see its `run_e2e.sh`). It is a self-contained npm package with its own lockfile and does not use the Python harness, pytest markers, or the shared transport; the Python rules in this file (typed models, `Result` unions, basedpyright zero-error gate) do not apply inside it. Its only Python file, `fixtures/mock_llm_server/server.py`, is excluded from the e2e basedpyright gate via the root `pyrightconfig.json`

 ### The pull request check
 
-Every same-repository PR that adds, modifies, or renames a `tests/e2e/**/test_*.py` file runs those changed files three times. A change to the harness itself, meaning a root-level `tests/e2e/*.py` file or `pytest.ini`, `tests/e2e/gateway/`, `.github/e2e-stack/`, or the workflow, also runs the `access_control` suite and both JWT suites as canaries, because those files have no test of their own that exercises the stack. `.github/e2e-stack/select_tests.py` applies both rules. The stack config at `tests/e2e/gateway/stage_mirror_ci_config.yml` must declare every model the selected suites use; a missing one shows up as a failed test id in the public log. The suite's own single rerun for network errors and 5xx responses (see `pytest.ini`) applies on every pass, so a transport blip does not fail the check while a race inside a test still does. The stage-mirror stack has a control-plane backend, two gateways behind nginx, Postgres, Keycloak, Jaeger, and TLS cluster-mode Valkey. Realm-only edits also trigger these canaries.

+Every same-repository PR that adds, modifies, or renames a `tests/e2e/**/test_*.py` file runs those changed files three times. A change to the harness itself, meaning a root-level `tests/e2e/*.py` file or `pytest.ini`, `tests/e2e/gateway/`, `.github/e2e-stack/`, or the workflow, also runs the `access_control` suite and both JWT suites as canaries, because those files have no test of their own that exercises the stack. `.github/e2e-stack/select_tests.py` applies both rules. The stack config at `tests/e2e/gateway/stage_mirror_ci_config.yml` must declare every model the selected suites use; a missing one shows up as a failed test id in the public log. The suite's own single rerun for network errors and 5xx responses (see `pytest.ini`) applies on every pass, so a transport blip does not fail the check while a race inside a test still does. The stage-mirror stack has a control-plane backend, two gateways behind nginx, Postgres, Keycloak, Jaeger, and TLS cluster-mode Valkey. Realm-only edits also trigger these canaries. The stack exports every gateway address in `LITELLM_PROXY_REPLICA_URLS`, so model registration waits until each gateway lists the new model rather than whichever one the load balancer answered from. Documentation, deleted-file, and application-only changes do not start the stack or request environment approval. The `ui/`, `claude_code/`, `load/`, and `secret_manager/` directories, `batches/test_managed_files_enforcement_e2e.py`, `llm_translation/realtime/test_realtime_pipecat_audio_e2e.py`, and `guardrails/test_presidio_masking_e2e.py` remain outside this check because they use separate tooling or need a differently configured stack: the pipecat audio suite skips itself at import time unless the NLTK `punkt_tab` data is installed, and the presidio suite fails without the analyzer and anonymizer services this stack does not start. `logging/test_otel_v2_langfuse_generation_output_e2e.py` is marked `otel_v2` and deselects itself unless `E2E_OTEL_V2` is set, because it needs a gateway booted with `LITELLM_OTEL_V2=true` and Langfuse credentials, neither of which this stack provides, so run it with `E2E_OTEL_V2=1` against a local OTel v2 proxy. The Redis chaos test under `load/` needs a proxy it can pause the Redis of on the same host (`gateway/redis_chaos_ci_config.yml`), which `.github/workflows/test-e2e-redis-chaos.yml` boots, and which the Buildkite `e2e-redis-chaos` step in project-releaser runs co-located with Postgres and Valkey in one pod; it is deselected unless `E2E_REDIS_CHAOS` is set. The `secret_manager/` lanes each need a proxy configured against their own secret manager (see Secret manager lanes below)
 
 Every selected file must execute at least one passing test in each pass, and any test failure, collection error, or entirely skipped or deselected file fails the check. A file whose tests are all marked skip therefore cannot pass this check, so unskip at least one of them, or add the file to `UNSUPPORTED` in `select_tests.py` with the reason, before changing one. A failed pass stops the run. The public log prints pytest's one-line summary for each pass, including the rerun count, and names each failed or errored test as `classname::name`, so a retried network error or a failing test is visible without the raw output. The final `e2e-changed-tests` job succeeds only when no supported test files changed or the approved run completed all three passes. Fork PRs with selected tests fail this gate until a maintainer brings the reviewed change onto a same-repository branch

+### Secret manager lanes
+
+`key_management_system` is global to the proxy, so the `secret_manager/` tests run once per backend, each against its own proxy. The backends are `hashicorp_vault` and `cyberark` (CyberArk Conjur). `E2E_SECRET_MANAGER` opts in and names the backend (a key of `secret_backends.BACKENDS`). The proxy boots from `gateway/secret_manager_<system>_ci_config.yml`, and the tests reach the same manager through that backend's `SecretStore`. The managers are enterprise features, so the proxy needs a license. `secret_manager/backend.sh` runs any backend in Docker and writes its env, so every lane runs the same way locally:
+
+```bash
+bash tests/e2e/secret_manager/backend.sh up cyberark
+(set -a; . ~/.cache/litellm-e2e-secret-manager/cyberark/proxy.env; set +a; env -u OPENAI_API_KEY LITELLM_LICENSE=... \
+  LITELLM_MASTER_KEY=sk-1234 DATABASE_URL=... uv run litellm --config tests/e2e/gateway/secret_manager_cyberark_ci_config.yml --port 4000)
+(set -a; . ~/.cache/litellm-e2e-secret-manager/cyberark/tests.env; set +a; OPENAI_API_KEY=... \
+  uv run --group e2e-dev pytest tests/e2e/secret_manager/ -v)
+bash tests/e2e/secret_manager/backend.sh down cyberark
+```
+
+`E2E_SECRET_MANAGER_PORT` moves the manager off its usual port (8200 for Vault, 8080 for Conjur), and `E2E_SECRET_MANAGER_DIR` moves the env files. Keep that directory private, because both files hold a working admin credential. Keep `OPENAI_API_KEY` out of the proxy's environment. The tests copy the runner's key into the manager under a fresh name per test, so a passing call proves the key came through the manager rather than the `os.environ` fallback `get_secret` takes when the manager errors
+
+A backend declares what it supports in its `SecretBackend.capabilities`, and a test that needs something not every backend does carries `@pytest.mark.requires_capability(...)`, so it is deselected, not failed or skipped, on the lanes that lack it. CyberArk has no `deletes_stored_keys`, because the proxy's delete answers `not_supported` and Conjur keeps the key, so the delete test runs only on the Vault lane
+
+To add a backend, leave the tests and markers alone and add:
+
+1. `secret_manager/secret_store_<system>.py`: a `SecretStore` (`write`, `read` returning None when absent, idempotent `destroy`) over the manager's own API through `e2e_http`'s external helpers, read from `E2E_<SYSTEM>_*` env vars, and a `SecretBackend` whose `system` is the litellm `KeyManagementSystem` value and whose `capabilities` lists what it supports
+2. its entry in `secret_backends.BACKENDS`
+3. `gateway/secret_manager_<system>_ci_config.yml`, a copy of an existing lane's with only `key_management_system` changed
+4. an `up_<system>` function in `secret_manager/backend.sh` that starts the manager and writes `proxy.env` and `tests.env`
+5. a CI step that runs `backend.sh up <system>` (or the same containers as sidecars), boots the proxy with `proxy.env` and a license, and runs pytest with `tests.env`
+
 ### Record and replay
 
 Record/replay scopes to the proxy's provider-bound traffic only. In `E2E_FIXTURE_MODE=record` the harness boots a local provider-edge server, edge-wired tests register their deployments with an `api_base` pointing at it, and every provider call the proxy makes is forwarded verbatim and written to a fixture bundle (default `tests/e2e/.fixtures`, override with `E2E_FIXTURE_DIR`). `E2E_FIXTURE_MODE=replay` runs the same tests against the same live proxy and database, but the edge answers the proxy's provider calls from the bundle instead of the provider, so the run makes zero provider calls and spends nothing while key auth, routing, cost calculation, and spend-log writes all still execute for real. Unset (or `live`) behaves exactly as before the knob existed. Both record and replay need the proxy up; only the provider is taken out of the loop

+### Messages and Markdown
+
+`ChatMessages` owns the shared list renderer. `ChatMessageContent` renders one message without a list wrapper so a transcript scroller can own each row. Both retain user editing, reasoning, tool output, copying and response metrics
+
+Use the official registry `Bubble` and `BubbleContent` primitives. User messages use the muted variant and end alignment. Assistant messages use the ghost variant at full available width. Keep paragraph spacing and list markers in the shared Markdown renderer. GFM tables use the shared Table primitives, which provide horizontal scrolling. Forward Markdown cell styles so column alignment survives rendering
+
+LiteAdmin passes `allowImages={false}` to show image descriptions without automatically requesting external image URLs from administrative answers. Other chat consumers retain image rendering by default
+
+Scrolling belongs to the conversation container. LiteAdmin uses official MessageScroller items with stable chronological IDs; a pending action and its result stay in the same row. Its inline action review is an explicit product exception to the AlertDialog confirmation pattern below

 ## Known gaps (tracked, not blockers)
 
-These are real, current gaps in this codebase's shadcn setup — don't silently work around them by reinventing the missing piece with raw Tailwind; either use the documented substitute above or flag the addition as its own change:
+Card, Textarea and sonner are installed. Earlier versions of this document listed them as missing and encouraged parallel implementations; use the shared owners above
 
-1. **No `Card` component.** Substitute: bordered div (`border rounded-lg p-4 bg-card`), already the established pattern.
-2. **No `Textarea` component.** Substitute: raw `<textarea>` with `border-none outline-none resize-none`, only inside an already-bordered container (chat composer).
-3. **No `sonner`.** Substitute: existing `MessageManager`.
-4. **No shadcn `Sidebar` primitive block** (`SidebarProvider`/`SidebarMenu`/etc). Substitute: the "Sidebar nav item" pattern above, built from `Button variant="ghost"` + the `sidebar-*` tokens.
+The shadcn Sidebar primitive block (`SidebarProvider`/`SidebarMenu`/etc) is still absent. Use the "Sidebar nav item" pattern above, built from `Button variant="ghost"` and the `sidebar-*` tokens

Subject: [PATCH 16/16] fix(mcp): preserve credential authority in DCR bridge
 authentication (#42563)

* fix(mcp): admit dcr_bridge envelope alongside an explicit litellm credential and mint under jwt principals

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* style(mcp): suppress LIT002 on concrete dict header payloads

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(mcp): mint bridge envelope for jwt mapped to a key without a user_id

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(mcp): mint and admit bridge envelopes under the master key

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(mcp): bind mapped JWT envelopes to stored key tokens

* fix(mcp): preserve master envelope scope enforcement

* fix(mcp): reject bridge minting that loses JWT restrictions
