📝 WalkthroughWalkthroughThe change adds bounded agent requests and SSE buffers, concurrent login verification limits, container log size and history limits, WebSocket backpressure handling, registry redirect refusal, and command credential redaction. It adds regression tests for these controls. Documentation covers login-attempt configuration, container log limits, and safer hook examples. A security review report records the remediations and validation scope. Possibly related PRs
Mergeability Score: 🟠 High · up to The new transport limits do not fully prevent oversized log messages, stalled container-log requests, or asynchronous agent queues from consuming resources or hanging API calls, and one authentication test does not prove that redirect limits are replaced correctly. These availability and correctness risks should be fixed before merging. 🚥 Pre-merge checks | ✅ 2✅ Passed checks (2 passed)

Inline comments:
In `@app/agent/AgentClient.ts`:
- Around line 467-483: Update buildRequestConfig and the synchronous
runRemoteTrigger/runRemoteTriggerBatch request path to use an execution-aware
trigger timeout instead of the fixed AGENT_REQUEST_TIMEOUT_MS, while preserving
the 30-second timeout for 202-acceptance update routes. Reuse the existing
operationId-based duplicate protection and ensure the timeout accommodates the
command trigger’s 60-second execution window.
In `@app/api/auth-lockout.ts`:
- Around line 126-129: Update parsePositiveIntegerEnv to validate the entire
environment value as a positive, safe integer before parsing, rejecting strings
with trailing characters, decimal syntax, or unsafe magnitudes; retain
DEFAULT_MAX_CONCURRENT_LOGIN_ATTEMPTS for invalid or absent values and preserve
the maxConcurrentLoginAttempts configuration flow.
- Around line 508-517: Wrap the passport.authenticate invocation in the
login-attempt flow with try/catch so synchronous middleware errors are handled
when the callback is never reached. In the catch path, call finishAttempt()
before forwarding the error to next(error), while preserving the existing
callback cleanup behavior.
In `@app/api/container/logs.ts`:
- Around line 273-279: Replace the buffered
watcher.dockerApi.getContainer(container.name).logs call with a one-shot Docker
HTTP stream using follow: false; count incoming bytes and destroy the source as
soon as the 16 MiB limit is exceeded, returning HTTP 413 before any 200 response
begins. Preserve normal log handling for within-limit payloads and avoid relying
on tail or follow: true.
In `@app/triggers/providers/command/Command.ts`:
- Around line 214-220: Update the command execution logging around the
stdout/stderr handling to stop interpolating raw child-process output; use fixed
status messages or the project’s approved secret-aware redactor instead.
Preserve the existing info/warn severity and add regression coverage for tokens
emitted through both stdout and stderr.
In `@content/docs/current/api/container.mdx`:
- Line 595: Update the API documentation for the log endpoint around the tail
parameter to state the 16 MiB maximum log payload and that oversized payloads
return HTTP 413; also add HTTP 413 to the documented response list.

- Around line 29-40: Update the vi.hoisted test setup to save the existing
DD_AUTH_MAX_CONCURRENT_LOGIN_ATTEMPTS value and set it to '2' before module
import, then restore the saved value in afterAll alongside the other environment

In `@app/api/container/logs.ts`:
- Around line 172-227: Update the Docker log stream promise in the visible
stream-handling block to settle when the stream emits close, using the existing
settled guard and rejecting if it closes before end. Add a read timeout for
stalled Docker daemon sockets that destroys the stream and rejects the promise,
ensuring the timeout is cleared whenever the stream settles.
In `@app/registries/Registry.test.ts`:
- Around line 2008-2025: Harden the test around Registry.callRegistry by have
authenticate return a non-zero maxRedirects value, then assert exactly one Axios
call and verify that call’s maxRedirects is 0 rather than matching any
invocation. Keep the test focused on preventing authentication options from
reintroducing redirects.

dial callback into the code immediately before modem.dial, so stalled connection

single-completion behavior, and ensure timeout handling still destroys any
