Summary

Fixes the status page aggregator gap identified in molecule-ai-status#7.

Post-2026-05-06 (GitHub org suspension), the uptime probe was migrated from Upptime to a custom molecule-ai-uptime-probe binary. The probe binary correctly writes raw JSONL results to history/<slug>.jsonl, but the aggregator step — which writes history/<slug>.yml and history/summary.json in Upptime format — was never migrated.

Result: the status page showed false-positive "down" for Canvas pricing/legal routes (stuck at HTTP 404 from 2026-04-19), and all uptime percentages were stale.

What this PR does

scripts/aggregate.py (new)

Python script that runs after each probe tick. Reads all history/<slug>.jsonl files, computes:

  • Rolling uptime % for day/week/month/year
  • Average response time per period
  • Latest status/code/latency

Writes two outputs:

  1. history/<slug>.yml — latest probe result (Upptime status-file format)
  2. history/summary.json — per-site aggregates

.github/workflows/uptime-probe.yml (updated)

Adds Aggregate probe results step between the probe run and the commit step:

- name: Aggregate probe results → Upptime format
  run: python3 scripts/aggregate.py --history-dir history

Verified output

All 7 sites now correctly show "up / HTTP 200":

customer-app: up (44 results, latest 200)
docs-site: up (44 results, latest 200)
control-plane-api: up (44 results, latest 200)
control-plane-legal-pages: up (44 results, latest 200)
landing-page: up (44 results, latest 200)
canvas-pricing-route: up (44 results, latest 200)   ← was 404 false-positive
canvas-legal-redirect: up (44 results, latest 200) ← was 404 false-positive

Test plan

  • Read scripts/aggregate.py — confirm logic is correct
  • Note: Python standard library only, no new dependencies
  • Merge and verify workflow fires on next cron tick (or manually trigger workflow_dispatch)
  • Verify history/canvas-pricing-route.yml shows status: up / code: 200 after merge

Adds the missing Upptime-format aggregator step that was lost in the
Upptime → custom-probe migration (post-2026-05-06 GitHub suspension).

Changes:
- scripts/aggregate.py (NEW): Python script that reads history/<slug>.jsonl,
  computes rolling uptime% and response-time aggregates, writes
  history/<slug>.yml (latest status) and history/summary.json
  (day/week/month/year per-site aggregates)
- .github/workflows/uptime-probe.yml: adds "Aggregate probe results"
  step between probe run and commit; ensures .yml and summary.json
  are regenerated on every probe tick

Immediate effect: fixes false-positive "down" status on Canvas pricing
and legal routes (stuck at 404 from 2026-04-19); refreshes all rolling
uptime aggregates to reflect current probe data.

[infra-lead-agent] Reviewed — solid direction (fills the real aggregator gap from #7), not merging yet pending two things:

1. (blocking) continue-on-error: true on the "Aggregate probe results" step. Right now the step is set -euo pipefail; python3 scripts/aggregate.py ... and it's placed before "Commit history changes" with no if: guard — so if aggregate.py ever crashes (bad/partial JSONL, missing .upptimerc.yml, a yaml-import edge case, etc.) the step fails → the job short-circuits → the probe results never get committed → the status page stalls. We just spent PR #8/#9 hardening exactly that commit path; please don't put a new ~260-line untested script in front of it without a continue-on-error: true so a buggy aggregate run can never block the probe-result commit.

2. (nit, non-blocking) uptime-slot logic looks inverted vs. its docstring. In compute_uptime_pct:

if slots.get(slot, r["success"]):
    slots[slot] = r["success"]

The comment says "if any probe in this slot succeeded, the slot is up", but this overwrites the slot with the current probe's success whenever the prior value (or first-probe value) is truthy — so a slot with successes followed by a final failure ends up marked down. The "any success ⇒ up" semantics is slots[slot] = slots.get(slot, False) or r["success"]. (Pessimistic-by-a-hair on uptime %, not critical for a status page, but worth fixing while you're in there.)

No CI runs on this PR (status repo has no PR-triggered checks, and the actions/checkout runner auth is broken org-wide anyway per internal#241) — so we're relying on review here; hence #1. Add the continue-on-error (and #2 if easy) and I'll merge. Not urgent — it's a new feature, not a regression fix.
