Failed jobs: basic: proxy port fallbacks, ci-fix

Failed job 'basic: proxy port fallbacks' (step 'Check proxy port fallbacks match their definitions', .github/scripts/check-proxy-port-fallbacks.sh) failed with two errors: .opencode/opencode.jsonc has no {env:CODEX_PROXY_PORT:-18744} baseURL — the fallback must match the codexProxyPort definition (18744); a bare {env:CODEX_PROXY_PORT} resolves to an empty port outside a home-manager shell (#434) and designCodeProxyPort definition not found in home/common/default.nix. — exit code 1. The 'ci-fix' job also failed at Set up job (staging archive not found for developing-today/code@main SHA 8482cc3). This run completed late (created 2026-11-03T21:20:00Z, updated 2026-11-04T00:20:48Z — its ci-fix job only ran at 00:20Z) and was caught by the main-ci watch failure-filtered list; it is the newest of 8 same-workflow failures in the window (41714259288, 41715541679, 41715946129, 41716919087, 41718795540, 41720507914, 41720613061, 41720831856), all the same breakage. No open issue tracked this run (run-id search empty; 'nix ci main' search returned only unrelated items — closest #4940 is about this job never running on pull requests, a different problem).

Filed by main-ci-failure-fix-trigger (fleet). One fix track per failing workflow; duplicates are suppressed until this issue closes.

Acceptance criteria

The basic: proxy port fallbacks job is green on main: check-proxy-port-fallbacks.sh exits 0.
Both defects named in the filing are dispositioned: the .opencode/opencode.jsonc CODEX_PROXY_PORT fallback matches the codexProxyPort definition (18744), and designCodeProxyPort is found in home/common/default.nix — or the check's expectation is corrected with the reason recorded on this issue.
No duplicate implementation: if task 8998 (the fix follow-up from main-broken: developing-today/code nix ci @ae4bb71 — basic: proxy port fallbacks #5240's triage) covers the same defects, this issue's work joins that task instead of opening a parallel fix.

Intake review

Related: Sibling: #5240 + its fix task 8998. Workflow: .github/workflows/nix-ci.yml, script .github/scripts/check-proxy-port-fallbacks.sh.

Notes: CI-watch filing from nix ci run 41720831856 @a9101acb. Verified still live: no merged PR references this issue (search this run: none). The two check errors are concrete and reproducible from the filing's log excerpt. Close relative: #5240 (stale CODEX guard row breaking the same proxy-port job family) whose triage enqueued fix task 8998 — dedupe against it first; the overlap is exactly the designCodeProxyPort / fallback-definition surface. The same run's ci-fix job failure (staging archive not found) is the fleet's recurring staging-infra transient, not this issue's code defect. Effort s.

— fleet monitor intake (protocol §5), 2026-11-03 20:12 CST run. Verified still live this run per the notes above.
