devantler-tech/ksailmain is red: the TODOs workflow fails on head 6ef410b (run 42510034075, failed again on re-run) with scanner incomplete: diff read failed. That head is ksail#8182, which regenerates the Go licence notices, so its compare diff is 54 MB (63 files).
The guard's fetch buffers every upstream body under one 16 MiB cap and fails closed above it. So the compare read and the bound commit fallback both return 502, deterministically, and every later push that regenerates the notices will turn main red again.
What
maxAPIResponse (16 MiB) still bounds JSON evidence.
maxDiffResponse (256 MiB) bounds a body requested as application/vnd.github.v3.diff.
A body above either bound is still refused, never truncated, so the fail-closed contract is unchanged.
Validation
RED first: the new TestLargeDiffWithinDiffCapIsServed/diff_above_JSON_cap failed with status=502 … diff read has no successful bound fallback before the change.
GREEN: go vet ./... and go test ./... in .scripts/todo-guard: 108 passed. That includes the two refusal cases: a diff above the diff bound, and JSON above 16 MiB.
gofmt -l is clean.
After this merges and is released, the ksail consumer pin needs to move to the new version for its main to go green (its next small push will also clear the head).
The guard buffered every upstream API body under one 16 MiB cap and failed
closed above it. A push that regenerates large generated files yields a far
larger diff (ksail#8182: 54 MB of licence notices), so the TODO scan failed
on every retry and turned the consumer's main red.
Diff bodies now get their own 256 MiB bound; JSON evidence keeps 16 MiB, and
a body above either bound is still refused rather than truncated.

Walkthrough
The guard uses a 16 MiB limit for JSON responses and a 256 MiB limit for diff responses. The default fetch uses the JSON limit. The diff route uses the diff limit. Response reads stop at one byte beyond the selected limit, and read errors or oversized bodies produce an incomplete response. Tests cover the configured limits and verify that JSON routes retain the JSON limit.
The change admits larger diffs while retaining the JSON size limit and refusing oversized responses. No concrete merge-blocking issue remains; testing a larger response under the production bound would improve regression coverage.

Explanation
The title names the main change: push diffs above the 16 MiB JSON bound are now served. The raw summary confirms a separate 256 MiB limit for diff-route responses, with the JSON limit kept for other routes. The title is specific and matches the changeset.
Full details: Description check
Explanation
The description explains the failure: the ksail main TODOs workflow fails because a 54 MB compare diff exceeds the shared 16 MiB cap. It states the fix: a separate 256 MiB bound for diff responses, with JSON still capped at 16 MiB and oversized bodies still refused. It also lists validation steps and a follow-up consumer pin update. This relates directly to the guard.go and guard_test.go changes.
Full details: Docstring Coverage
Explanation
Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 2 files.
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

Review comments at @.scripts/todo-guard/guard_test.go:
- Around line 498-499: Update the JSON-case request in the test around tc.accept
to use state=open so it reaches fetch instead of being rejected by the route
guard; assert that the upstream was called and reading the returned list failed
because it exceeded the JSON size limit.
- Line 480: Update the test around maxDiffResponse so it verifies the production
diff cap rather than masking it with an override: assert the production default,
or check a diff larger than the test override without changing maxDiffResponse.
Ensure the test fails if the production cap drops below the required size.
Review comments at @.scripts/todo-guard/guard.go:
- Around line 227-229: Update the limit selection around req.Header.Get so
maxDiffResponse applies only when the validated route is a diff route, not
merely when the request carries the diff Accept header. Preserve the normal
limit for non-diff routes regardless of their Accept header.
- Line 193: Update the diff-fetching and scanning flow that uses maxDiffResponse
to bound memory use when handling accepted diffs. Avoid buffering the full diff
in memory; use a bounded-memory approach that still scans the entire accepted
diff without truncating it, preserving the existing size limit and acceptance
behavior.

Apply maxDiffResponse only where the bound diff route reads, so another route
keeps the JSON bound whatever Accept header it sends. Tests now pin the
production bounds, send the oversized JSON case through an allowed route and
assert the upstream read was reached.

The larger 256 MiB bound is passed only from diff(). That route still requires Accept: application/vnd.github.v3.diff, the bound compare/commit/pull path and a diff --git prefix. Every other route keeps the 16 MiB JSON bound, whatever Accept header it sends. The case diff Accept on a JSON route covers that.
Over-bound bodies are still refused, not truncated: LimitReader(limit+1) plus len > limit. The compare refusal still yields the 502 bound-fallback path, so the fail-closed contract is unchanged.
Peak memory is about 2× the body (buffer plus string copy), roughly 512 MiB at the cap. That is well within a hosted runner.
The test restores maxDiffResponse with t.Cleanup and does not run in parallel, so the package-level var mutation is safe.
The 60 MiB case is read under the production bound, so it exercises the real constant beyond the 54 MB motivating diff.
Readiness at 69165ef79d3d28ae83d3ec76c0e05ffb3f62e903:
Tested: CI green (184 pass, 60 skipped, 1 neutral, no failures). RED/GREEN proof is in the body. TestLargeDiffWithinDiffBoundIsServed drives the real guard ServeHTTP against an upstream fixture. It serves a 60 MiB diff under the production bound (the ksail#8182 diff that motivated this was 54 MB) and refuses over-bound diff and JSON bodies.
