ci(context7): treat too-early as a warning and refresh daily (LAB-8511)

[27Bslash6]

Context7 accepts one refresh per library per 10 days. It answers an earlier request with HTTP 400 {"error":"too-early",...}, and this workflow failed on that. The change that triggered the run was then never asked for again, so Context7 kept serving the older index.

Change

• Response handling: a 400 whose JSON error is too-early prints a ::warning:: and exits 0. Every other non-2xx still fails the run, including a 400 with any other error, a 400 whose body is not JSON, 401 and 404. The 202 warning and 2xx success arms are unchanged.
• Schedule: a daily schedule: (23 5 * * * UTC) joins the existing triggers: workflow_dispatch, plus push to docs paths on protocol or release: published on the SDKs. A change that lands inside the window is usually refreshed within 11 days: the window reopens at most 10 days after the change, and the next daily run normally lands within 24 hours of that. GitHub runs schedules best-effort and can delay or drop a run, so this is a typical bound, not a guarantee; a dropped run is retried the next day. On the other days the scheduled run reads too-early and stays green with a warning.
• Trade-off: the schedule spends each 10-day window as it opens, so a docs push or release rarely refreshes at once. Before this change, a push or release inside the window was never refreshed at all. Gating the schedule on "something changed since the last accepted refresh" would need either stored state or a last-indexed time from Context7, and its API documents neither, so the header comment states this cost instead.

The same edit lands in the context7-refresh.yml of protocol, cachekit-py, cachekit-ts, cachekit-rs and cachekit-core.

How the five copies were checked

A script loaded each repo's workflow, took the refresh step's run: script verbatim and ran it under bash --noprofile --norc -eo pipefail, which is GitHub's default shell for Linux run: steps. A stub curl returned each of 10 status and body pairs: the exact too-early body Context7 returns, a reformatted too-early JSON, a 400 with a different error that mentions too-early in its message, a non-JSON too-early body, an empty 400, 401, 404 library_not_found, 500, 202 and 200. All 50 runs (5 repos × 10 cases) gave the expected exit code and annotation, and every repo gave the same result for each case. The same script checked that each workflow carries the schedule and keeps workflow_dispatch. actionlint is clean on all five files.

Summary by CodeRabbit

• Automation
  • The Context7 refresh runs daily, when a release is published, or when manually triggered.
  • Scheduled runs are best-effort and retry daily, respecting the 10-day refresh limit.
  • “Too early” responses generate a warning without failing the run. Other HTTP 400 responses generate an error and fail the run.

Walkthrough

The Context7 refresh workflow adds a daily scheduled run alongside published-release and manual triggers. It handles too-early HTTP 400 responses as warnings and fails for other HTTP 400 responses.

Changes

Context7 refresh workflow

Layer / File(s)	Summary
Schedule and HTTP 400 handling .github/workflows/context7-refresh.yml	The workflow adds a daily trigger at 05:23 UTC alongside published-release and manual triggers. It warns without failing for too-early HTTP 400 responses. Other HTTP 400 responses produce an error and exit with status 1. Comments describe the 10-day refresh limit and daily retries within 11 days.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 6195e

The workflow adds daily Context7 refresh attempts; a change may wait for the next available refresh window, as documented. That is the intended tradeoff, and no actionable merge-blocking risk remains.

### [1/1] .github/workflows/context7-refresh.yml:15
Issue identified during code review:
Logic error in the schedule trigger: the daily cron sends a refresh every day even when nothing is pending, so Context7 accepts a scheduled refresh roughly every 10 days and the 10-day window is almost always in use. When a release is published, its run almost always gets HTTP 400 too-early, so the new docs wait about 5 days on average (up to 10) for indexing; before this change, a release more than 10 days after the last refresh was re-indexed immediately, as the header comment intends. Fix: on schedule events, POST only if a previous run recorded a pending (too-early) refresh in a cache, artifact, or repo variable, or if the latest release or default-branch commit is newer than the last accepted refresh.
Reference implementation (from code review):

// .github/workflows/context7-refresh.yml:15
schedule:
    - cron: "23 5 * * *"
# and in the job, on schedule events, skip the POST unless a previous run recorded a pending (too-early) refresh or there is a release/commit newer than the last accepted refresh
