README.md and site/data.json were written with os.Create/os.WriteFile,
so a write that failed midway left the repo front page truncated, while
history.jsonl already used a temp-file-plus-rename. Extract that pattern
into atomicWriteFile and route all three writers through it.
Also sort snapshots by date when reading history.jsonl: delta windows
pick the newest snapshot inside the window by scan order, which silently
produces wrong deltas if a hand edit or a merge of two concurrent runs
interleaves lines.
Cover the README renderer, which had no test beyond sanitizeCell, and
name the generated paths as constants instead of repeating literals.
Coverage 65.1% -> 75.7%.
GitHub fetcher (github.go):
- add 30s HTTP client timeout (was http.DefaultClient with no bound)
- chunk GraphQL alias requests at 50 repos to stay clear of abuse detection
- abort the run on any partial GraphQL error or missing repo rather than
silently shrinking the README and poisoning the next delta
- retry transient failures (network, 5xx, 429) with 2s/4s/8s backoff
History layer (history.go):
- key snapshots by canonical owner/repo from agents.yml instead of the
rename-resolved NameWithOwner returned by the API; carry a lazy
migration map so existing aaif-goose/goose entries fold into block/goose
on next read with no manual data edit
- tighten the 7d delta window to (cutoff-3d, cutoff] so a missed cron week
no longer mislabels a 90d-old comparison as Delta7d
- replace the snapshots[:0] aliased filter loop with slices.DeleteFunc
- log malformed JSONL lines to stderr with line numbers instead of
silently skipping them
- write history.jsonl atomically via tmp file + rename so a crash
mid-write can no longer truncate accumulated history
Plus collapse a few redundant fmt.Errorf wraps, drop a named Config type
that was used once, inline the single-call sortByStars helper with a
deterministic tiebreaker on canonical key, and use filepath.Base instead
of hand-rolling a basename.
Includes unit tests covering the 7d window edges, canonical-key
migration, atomic write path, malformed-line tolerance, YAML validation,
and markdown cell escaping.
