| # Fires when published prices actually change on the branch the site deploys | |
| # from — which is the only moment a subscriber would want to hear about. | |
| # | |
| # Human-reviewed merges arrive through the push trigger. Bot-authored commits | |
| # use GITHUB_TOKEN, which GitHub deliberately prevents from triggering another | |
| # workflow; sync-pricing.yml therefore dispatches this workflow explicitly only | |
| # after it has successfully pushed a published catalog to main. | |
| # | |
| # The script exits 0 without sending anything when ALERTS_API or NOTIFY_SECRET | |
| # is unset, so this stays green until the worker has a domain. | |

| # Two pushes in quick succession must not race into two overlapping fan-outs. | |
| # The worker deduplicates by event id as well, but not queueing them at all is | |
| # cheaper than relying on that. | |

| # Same trigger, different audience: subscribers hear about the change, | |
| # and so do the search engines whose model pages just went out of date. | |
| # | |
| # `continue-on-error` because this is an optimisation on top of ordinary | |
| # crawling. A refused submission must not turn a perfectly good pricing | |
| # update into a red build — the script already downgrades its own failures | |
| # to warnings, and this is the belt to that pair of braces. | |
