Subject: "web" service fails every fresh build — instant failure with no build logs (builder-qpcbvd)

Project: O Mercado Aventureiro (6d2ba6ca-9c0e-4767-982b-c369b1fb763d)

Environment: production (236cfdb9-d87c-4953-a142-ed83cad12c06)

Service: web (4dbf5621-0c89-4e9f-b38d-1b13fb962581)

Builder: RAILPACK, reported as "Metal builder builder-qpcbvd"

Source: GitHub repo NeiMac/mercado-aventureiro, root directory apps/web, branch main

Issue:

Since ~2026-08-26 21:00 UTC, every attempt to trigger a fresh build for the "web" service fails immediately, with no usable build log:

scheduling build on Metal builder "builder-qpcbvd"

scheduling build on Metal builder "builder-qpcbvd"

Deploy failed

No further output — fails before any dependency install or source copy step. Happens regardless of trigger:

GitHub push to main (webhook-triggered deploy)

Manual railway up via CLI (4 attempts, different commits, same result)

Manual redeploy via the Railway API

The only thing that succeeds is a "redeploy" that reuses an old image without rebuilding — keeps the service up, but on stale code.

Failed deployment IDs (same signature): 1866f203, 14565d89, f1d1ba2f, 5bd14124, 937d440e, bc2af56e, fe42968c, 46626dc5 (all between 2026-08-26 21:07 UTC and 2026-08-27 01:12 UTC).

For comparison: other services in the same project (api, scheduler) built and deployed successfully from the same push around 00:46–00:47 UTC — so this looks specific to the web service's build path, not account/repo-wide.

What we need: help finding why builder-qpcbvd fails to start a real build for this service, and getting a fresh build of current main (commit 74f1fa9) live.
