Pass 2 elements to SetRetryBackoff (matching maxRetryAttempts-1 = 2)
and check the error return. Previously passing 1 element silently
failed, causing tests to fall back to default {1s, 2s} backoffs.
Fixes self-review finding: 429Retry tests now run in <10ms instead
of ~1s.
Implement FileReader conformance on the GitHub client: GetFileContent,
ListContents, path helpers, base64 decode. Includes compile-time
conformance checks for both PRReader and FileReader.
Requires PR B (#102). Part 3 of 3 for #80.
- Add maxFileContentSize (10 MB) limit to decodeBase64Content to prevent
resource exhaustion from oversized file content (security MINOR)
- Fix reversed NewClient arg order in TestGetFileContentAtRef_DotSegmentError
(GPT MINOR + Sonnet NIT)
- Remove 'waiting' from mapCheckRunStatus conclusion cases since it is a
status value not a conclusion, update comment (GPT NIT)
- Add TestDecodeBase64Content_SizeLimit test
- escapePath now returns an error when paths contain dot-segments
(".", "..") instead of silently rewriting them. This prevents
subtle API misses where callers pass "foo/../bar" expecting to
hit "bar" but the old code produced "foo/bar".
- Uses path.Clean for canonical form after validation.
- CommitStatus.Description for check runs is now empty string
instead of the raw conclusion enum. The conclusion is already
captured in the Status field via mapCheckRunStatus; storing it
again in Description was semantically inconsistent with commit
statuses where Description carries a human-readable narrative.
- Removed unused derefString helper.
- Added tests for escapePath valid paths, dot-segment rejection,
and GetFileContentAtRef dot-segment error propagation.
