Backend changelog: get-convex/convex-backend@precompiled-2026-08-14-0dda4d6...precompiled-2026-09-03-4d58e45 — release-to-release, deliberately not
...HEAD. The npm release notes cover the CLI/client surface; this
compare is the only changelog for backend internals.

Operator checklist (runbook)

• Skim the compare for env-var renames / migration notes
• Lockfile convex ≤ the anchored version (land any open Dependabot convex PR in this window)
• backup service healthy (fresh heartbeat) on beta
• Pre-upgrade convex export + env capture taken on beta
• Merge
• Deploy beta (pull + up -d --force-recreate backend dashboard keygen deployer), watch for MigrationComplete(N) — do NOT restart mid-migration
• Beta verified: /readyz 200, deployer [deploy] OK, dashboard loads, next backup cycle green
• Soaked ≥3 days on beta — earliest prod deploy: 2026-09-10
• Prod: fresh pre-flight (its OWN export), deploy, verify

CI note: this PR was opened by GITHUB_TOKEN, so pull-request CI
did not trigger. The workflow ran the FULL test suite (including
convex/deployPins.test.ts) and prettier on this exact commit — see
the run log.
To kick full PR CI anyway: close and reopen the PR.

A newer re-pin PR automatically closes this one ("superseded"); don't
push fixups onto this branch expecting them to survive that.
