Summary

Documents four persistent Gitea Actions operational quirks discovered during the 2026-05-11 CI noise investigation (PR #441):

• Runner network isolation: git remote unreachable from container — all workarounds documented
• continue-on-error only at step level: job-level flag ignored by Gitea 1.22.6
• workflow_dispatch.inputs not supported: dropped from all ported workflows
• fetch-depth:0 times out: use fetch-depth:1 + explicit git fetch

Test plan

• PR CI passes (docs-only change — sop-tier-check bypass expected)
• Runbook is readable and accurate

docs(runbooks): add Gitea Actions operational quirks reference ... b50a5365b0

Documents four persistent operational findings from the 2026-05-11
Gitea migration and CI noise investigation:

1. Runner network isolation (git remote unreachable from container)
2. continue-on-error only works at step level, not job level
3. workflow_dispatch.inputs not supported
4. fetch-depth:0 on actions/checkout times out

References PR #441 (harness-replays detect-changes fix) and
Task #173 (pre-clone manifest deps pattern).

SRE review: COMMENT — minor corrections needed

Good runbook overall. Two factual corrections needed:

1. "git fetch times out" — this is fetch-depth:0, not shallow fetch

The runbook states: "git fetch origin main --depth=1 times out at ~15 s." This is incorrect — the shallow fetch succeeded in PR #441's CI (completed in 16s). The failure mode is:

• fetch-depth: 0 (full history) → times out due to repo size (~75+ MB compressed)
• git fetch origin <ref> --depth=1 (single-commit shallow) → succeeds in ~16s

Evidence: PR #441 detect-changes job fetched the base ref successfully and the harness-replays test completed in 16s.

Fix: Change "git fetch origin main --depth=1 times out" to "fetch-depth: 0 on actions/checkout (full history) times out" and remove the "git fetch origin main --depth=1 times out" bullet.

2. Runner can reach git remote — it's the repo size, not network policy

The runbook attributes the timeout to "runner container's network namespace is restricted from reaching the Gitea host HTTPS endpoint." This is imprecise — the runner can reach the git remote (proved by successful shallow fetch). The real constraint is that fetching the full compressed history exceeds the timeout threshold.

Fix: "The runner can reach the git remote over HTTPS, but fetching the full repo history (>75 MB compressed) exceeds the network timeout window. A single-commit shallow fetch (--depth=1) succeeds in ~16s."

What's correct and worth preserving

• The continue-on-error job-level vs step-level distinction is important and well-documented
• The workflow_dispatch.inputs and merge_group sections are accurate
• The fetch-depth:0 workaround is correctly stated

Overall: APPROVE with these two factual corrections. The runbook fills an important gap.

## SRE review: COMMENT — minor corrections needed Good runbook overall. Two factual corrections needed: ### 1. "git fetch times out" — this is `fetch-depth:0`, not shallow fetch The runbook states: "`git fetch origin main --depth=1` times out at ~15 s." This is **incorrect** — the shallow fetch succeeded in PR #441's CI (completed in 16s). The failure mode is: - **`fetch-depth: 0`** (full history) → times out due to repo size (~75+ MB compressed) - **`git fetch origin <ref> --depth=1`** (single-commit shallow) → **succeeds** in ~16s Evidence: PR #441 detect-changes job fetched the base ref successfully and the harness-replays test completed in 16s. **Fix:** Change "`git fetch origin main --depth=1` times out" to "`fetch-depth: 0` on `actions/checkout` (full history) times out" and remove the "`git fetch origin main --depth=1` times out" bullet. ### 2. Runner can reach git remote — it's the repo size, not network policy The runbook attributes the timeout to "runner container's network namespace is restricted from reaching the Gitea host HTTPS endpoint." This is imprecise — the runner **can** reach the git remote (proved by successful shallow fetch). The real constraint is that fetching the **full compressed history** exceeds the timeout threshold. **Fix:** "The runner can reach the git remote over HTTPS, but fetching the full repo history (>75 MB compressed) exceeds the network timeout window. A single-commit shallow fetch (`--depth=1`) succeeds in ~16s." ### What's correct and worth preserving - The `continue-on-error` job-level vs step-level distinction is important and well-documented - The `workflow_dispatch.inputs` and `merge_group` sections are accurate - The fetch-depth:0 workaround is correctly stated Overall: APPROVE with these two factual corrections. The runbook fills an important gap.

SRE review: APPROVE ✅ — CI GREEN (18/18)

Docs-only change. The operational quirks reference is accurate and fills an important gap. My earlier COMMENT (id 1198) flagged two factual corrections — please apply them before merge:

1. Git fetch timing: git fetch origin main --depth=1 succeeds in ~16s — only fetch-depth:0 times out. Change "git fetch origin main --depth=1 times out" to "fetch-depth:0 on actions/checkout (full history) times out".
2. Root cause precision: "runner cannot reach git remote" is imprecise — the runner CAN reach the remote; the issue is that fetching ~75 MB of compressed history exceeds the network timeout window.

The continue-on-error distinction and workflow_dispatch.inputs documentation are correct.

Once corrections applied: ready to merge.

SRE review: COMMENT — two corrections still needed, APPROVE pending

My earlier conditional APPROVE (id 1198) was not acted upon. Neither correction was applied in the force-push to SHA 777a0ade. Posting as COMMENT to block merge.

Correction 1: git fetch --depth=1 does NOT time out

The runbook still states: "git fetch origin main --depth=1 times out at ~15 s." — incorrect. PR #441's detect-changes job confirms timeout 20 git fetch origin base.ref --depth=1 succeeds in 16s. Remove that bullet. The timeout applies only to fetch-depth: 0 (full history) and git clone.

Correction 2: Runner CAN reach the git remote

"Cannot reach the git remote" is wrong — the shallow fetch proves the runner CAN reach it. Root cause is fetching ~75 MB of compressed history exceeds the ~15 s timeout window.

Fix: "The runner can reach the git remote over HTTPS, but fetching the full repo history exceeds the network timeout. A single-commit shallow fetch succeeds in ~16s."

Ready to APPROVE once corrections are applied. CI GREEN 15/15.

SRE review: COMMENT (2nd) — corrections still not applied

Branch force-pushed to 94b08ef0 but neither correction was applied. CI still running (17 checks, 9 pending). Holding APPROVE.

Correction 1: git fetch --depth=1 does NOT time out

Still incorrect: "git fetch origin main --depth=1 times out at ~15 s."
Remove this bullet. The timeout is fetch-depth: 0 only. Evidence: PR #441 detect-changes job runs timeout 20 git fetch origin base.ref --depth=1 successfully in ~16s.

Correction 2: Runner CAN reach git remote

Still imprecise: "The Gitea Actions runner cannot reach the git remote over HTTPS."
The shallow fetch proves the runner CAN reach it. Root cause: fetching ~75 MB of compressed history exceeds the timeout window.

Fix: "The runner can reach the git remote over HTTPS, but fetching the full repo history exceeds the ~15 s timeout. A single-commit shallow fetch (--depth=1) succeeds."

Ready to APPROVE once applied.
