From d0691340f549378f8cae39490c1911368a5e9400 Mon Sep 17 00:00:00 2001 From: Aaron Stainback Date: Mon, 18 May 2026 09:39:13 -0400 Subject: [PATCH 1/2] rules(rate-limit-tier): wrap git network ops in timeout --kill-after per B-0615 Adds a sub-section to refresh-world-model-poll-pr-gate.md documenting the timeout --kill-after discipline for git network ops (fetch, push, ls-remote, clone) per B-0615 acceptance criterion #2. Discipline: timeout --kill-after=5s 30s git fetch origin main 2>&1 | tail -2 Caveats per B-0615 anchors: agent-side discipline is necessary but insufficient; timeout SIGTERM mid-git-worktree-add leaves partial extracts; orphan-count correlated NOT causal with push-hang. New empirical anchor: 2026-05-18T13:13Z-13:17Z observed worktree-add partial-extract failure during this very edit's authoring. Landed via REST git-data API (POST .../git/blobs,trees,commits,refs) because git push was hanging system-wide at authoring time. The REST bypass works when git push transport is stalled but REST endpoints remain responsive. Bus claim 187ab3d0 held by otto-cli; will release on merge.

Agent-controlled `timeout` discipline reduces orphan accumulation but cannot prevent it entirely while harness-internal wrappers fire bare fetches. +- **Even with `--kill-after`, `git worktree add` can leave partially-extracted file trees.** SIGTERM at mid-extract abandons the work-in-progress directory with a 85-byte `.git` pointer file and a fraction of the 5,500+ repo files. The worktree is unusable but `git worktree list` may not show it. Manual cleanup via `rm -rf ; git worktree prune` required. Observed empirically 2026-05-18T13:13Z–13:17Z during this rule's own authoring session. +- **Orphan count is correlated, not causal, with push-hang behavior.** Per B-0615's 2026-05-18T03:56Z breakthrough finding: even at zero orphans, `git push` can still hang silently at the receive-pack upload phase. `--kill-after` discipline is hygiene work that prevents orphan accumulation; it does NOT guarantee push-restoration. Open question for follow-up B-NNNN: actual causal mechanism of `git push` receive-pack stalls under multi-agent conditions. +- **Killing your own hung `git` subprocesses is operationally safe** (per [`claim-acquire-before-worktree-work.md`](claim-acquire-before-worktree-work.md) and B-0615 interim discipline). Use `kill -9 ` on YOUR OWN orphaned `git fetch`/`git worktree add`/`git push` processes when they block further work. Do NOT `pkill -f 'git fetch'` blindly — that affects peer agents' in-flight legitimate operations. + ### Composes with counter-with-escalation When rate-limit forces brief-acks (deferring substantive PR work), the [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](holding-without-named-dependency-is-standing-by-failure.md) counter-with-escalation counter still ticks. At brief-ack #6 the rule triggers forced decomposition. **Editing this rule, a memory file, or any other substrate via pure-git workflow IS decomposition that resets the counter** — the work is bounded, concrete, committed, pushed. Counter reset condition #3 ("Actually picking real decomposition work — Concrete artifact") is satisfied.
