The pipeline died at load, before it ever checked for new data. Fixed with extra-packages: local::. which installs cd itself and takes the library(cd) branch. 2. No permissions: block, so GITHUB_TOKEN was read-only and the log commit step's git push got a 403. 3. The log commit step was dead code anyway. logs/*.log is gitignored, so git add logs/ staged nothing and the git diff --cached --quiet guard short-circuited the commit. Only git push remained, and git push 403s during git-receive-pack ref advertisement even with nothing to push. Granting contents: write would have repaired a step that could never commit. The pipeline publishes to S3, not git, so the step is replaced with actions/upload-artifact@v4 and the token stays contents: read. issues: write is added for the auto-file-on-failure step in Phase 4. Both pipeline scripts now fail with a readable message when neither cd nor devtools is available, instead of a bare loadNamespace error.

No EDH pull, no COG rebuild, no S3 publish. Mirrors the --dry-run flag already on pipeline_stage3_edh.R; the env var lets the GitHub Action pick the mode without rewriting the command line. New STEP 0 runs on every path, live runs included. STEP 1/2 can exit 0 early when already current, and a live run does not touch S3 until STEP 5 — six hours in. Probing up front turns a credential problem into an immediate, legible failure instead of one buried at the end of a long job. Three probes: - EDH: HEAD the consolidated Zarr metadata, distinguishing a bad token (401/403) from an unreachable host. - AWS identity: sts get-caller-identity, so a missing or expired key reports as such rather than as an opaque S3 error. - AWS write: round-trip a sentinel object under _healthcheck/ and delete it. get-caller-identity only proves the credentials parse; it says nothing about whether this principal may write to the bucket, and that is exactly the class of failure this issue is about. Keyed by run id so concurrent runs cannot clobber each other. A failed delete warns rather than aborts, since the write is what STEP 5 actually needs. The EDH probe needs credentials on the curl handle plus httpauth = 1L (CURLAUTH_BASIC). Embedding them in the URL the way the Python fsspec calls do yields a spurious 401 in R: the 104-character token is not URL-encoded, and libcurl otherwise waits for a WWW-Authenticate challenge that EDH never sends. Handle-based credentials also keep the token out of any loggable string. Full matrix in findings.md.

Beyond proving the plumbing between live runs, it keeps the workflow active so GitHub does not auto-disable the cron after 60 days of repo inactivity, which is a silent failure no notification would catch. - A Resolve run mode step maps event to CD_DRY_RUN via plain if/elif/else on github.event_name and github.event.schedule. Deliberately not the nested ${{ a && b || c }} idiom, which mis-evaluates when the middle term is falsy, and dry_run can legitimately be false. Failure alarm: - A final if: failure() step opens a tracking issue, or comments on the open one, deduped by the climate-update-failure label so a run of red months yields one thread rather than four. Team-visible and durable, unlike watch-emails, which go only to the actor and depend on per-user notification settings. Covers the weekly dry run too, so a broken heartbeat self-reports. - Body carries run URL, trigger, cron, resolved mode, ref, commit and the last 50 log lines. Static parts come from an interpolating heredoc; the log tail is appended separately so backticks and $ in R/AWS output are never expanded by the step's shell. - The label did not exist (repo had only the 9 GitHub defaults) and has been created. Both the artifact path and the log tail are scoped to logs/update_*.log rather than logs/, which also holds three stale backfill logs tracked in the repo from before logs/*.log was gitignored.

Granting `contents: write` would have "repaired" a step that could never +commit anything, so it was replaced with an artifact upload and the token stayed +`contents: read`. Then the new dry-run probe found the fourth: the `EDH_TOKEN` +repo secret has been stale since 2026-04-14, exactly the date of the last green +run. Even with the first three fixed, the live run would still have died — six +hours later at the EDH fetch instead of four seconds in at the probe. + +The QA layer is the durable part. `--dry-run` / `CD_DRY_RUN` runs credential +probes, reads the STAC catalog and computes the target year, then exits before +any fetch or publish. Deliberately not a no-write mode: it round-trips a sentinel +object under `_healthcheck/`, because `aws sts get-caller-identity` proves the +keys parse and says nothing about whether the bucket is writable, which is the +exact class of failure that took this workflow down. A weekly cron runs it as a +heartbeat, which also keeps GitHub from auto-disabling the schedule after 60 days +of repo inactivity. Any failure opens a tracking issue, or comments on the open +one, deduped by label — team-visible and durable, unlike watch-emails that go +only to the actor. Two acceptance dispatches confirmed the whole chain including +the dedup path, and the alarm's first real customer was Bug 4 itself. + +Worth remembering: EDH's HTTP Basic auth needs `httpauth = 1L` on the curl +handle, since libcurl waits for a `WWW-Authenticate` challenge EDH never sends; +and credentials belong on the handle rather than in the URL, both because the +104-character token isn't URL-encoded and because it keeps the token out of +anything loggable. + +**Left open for the repo owner:** rotate `EDH_TOKEN` (`gh secret set EDH_TOKEN`). +The sandbox refused to let the agent overwrite shared CI credential material, +correctly. Until that lands, the live publish path stays unproven — it is +unchanged by this work, but cannot be exercised. If DestinE tokens are +short-lived this will recur, and the weekly heartbeat is what catches it. + +Closed by: PR for #78 (commits 62256d5, 041f16e, ca4e41e, 0f4a3cc) diff --git a/planning/active/findings.md b/planning/archive/2026-08-issue-78-climate-update-workflow/findings.md similarity index 71% rename from planning/active/findings.md rename to planning/archive/2026-08-issue-78-climate-update-workflow/findings.md index a958722..82615e2 100644 --- a/planning/active/findings.md +++ b/planning/archive/2026-08-issue-78-climate-update-workflow/findings.md @@ -155,3 +155,52 @@ Candidate years to fetch: 2026 `aws s3 ls s3://stac-era5-land/_healthcheck/` returns empty afterwards — the sentinel round-trip cleans up after itself. `CD_DRY_RUN=true` with no flag takes the same path. + +## Bug 4 (found by the new probe) — the `EDH_TOKEN` repo secret is stale + +The acceptance dispatch surfaced a **fourth** independent reason this workflow +could never have succeeded, on top of the three above. + +- The EDH probe passes locally with the token in `~/.Renviron` — HTTP 200. +- On the runner it returns **403**.
