Conversation
…L integrity + test gate Bundles 5 verified fixes to the autonomous loop, each with a runnable test (suite: 20 assertions across 2 files, all green from a clean base). 1. Stop discarding valid consensus on non-fatal cycle failures. A cycle that exits non-zero with is_error:true (transient subagent/MCP error) but still wrote a VALID consensus used to wipe the relay baton. Now conditionally restored -- validate_consensus is the gate. 2. Surface cycle-failure reason in --history and --dashboard. History prints a REASON column (table) / [reason] suffix (compact); dashboard prints it inline (red). Older records degrade to '-'. 3. Stop logging a false 'restored' when no backup exists. restore_consensus now returns a distinct status and warns when no .bak exists (first cycle, or deleted backup) instead of masking it. 4. Never corrupt cycle-history.jsonl. Writer escaped quotes/newlines but NOT backslashes -- a reason with a Windows path (C:\Users\foo) or trailing \ emitted an invalid escape; one bad line made every jq -s read return nothing (whole dashboard dead). Now escapes backslash first, collapses control chars, and self-checks each record with jq -e before append. 5. One-command test gate: tests/run-all.sh (CI-ready). See CHANGELOG.md for the user-facing breakdown. No npm bump needed -- create-auto-co clones this repo, so merged fixes reach new users on next install. Co-Authored-By: Claude <noreply@anthropic.com>

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
MODEL corrupted in Case 6 leaks into Case 7, defeating the "happy path" check.
MODEL='bad"model' (line 103) is never restored before Case 7 runs. Case 7 is meant to verify the primary (non-fallback) serialization path still works for a plain reason, but since MODEL is still invalid, append_cycle_history again hits the jq -e self-check failure and returns the sanitized fallback record — not the happy path it claims to test. The assertions (valid JSON, status round-trip) happen to pass under either path, so this silently loses coverage of the real "plain reason, ok status" case.

send_webhook and send_notification built JSON via printf with raw $MODEL / $status / $reason interpolated into string fields. A " or \ in any value broke the payload -- invalid JSON the receiver rejected or misparsed. The live trigger is the `error` event, whose reason ($3) comes straight from captured command output and routinely contains quotes + backslashes (e.g. 'parse error: "unexpected" at C:\Users\foo'). Add json_escape() helper; escape every string field (backslash first, then quote, then CR/LF/tab). Numeric fields untouched. Same bug class as the cycle-history backslash fix, applied to the fire-and-forget path. Added tests/test-notify-json.sh: 16 assertions over the real extracted functions (curl stubbed to capture payload), proving pathological MODEL/status/reason values produce valid, round-tripping JSON. Full gate now 36 assertions / 3 files, all green. Co-Authored-By: Claude <noreply@anthropic.com>

Pushed a second commit to this PR: hardened the Bug: both functions built JSON with Fix: new Test: added No change to behaviour on the happy path; this only prevents invalid-JSON posts when a field contains a special character. |
The corruption gate checked only that the three section headers exist. A consensus written with all headers but an EMPTY Next Action body passed as valid -- so the failure-recovery path logged KEEP and the next cycle started from a relay baton carrying no direction. The atomic .tmp->mv write protects against partial bytes, not against a structurally-complete-but-empty file. Reproduced red: validate_consensus(header-only) returns VALID for a file whose `## Next Action` section body is blank. Fix: extract the section body (awk, header up to next `## `) and require >=1 non-whitespace char. Scope is Next Action only -- it is the baton; Company State stays header-presence. Adds test Case 6 (headers + empty Next Action body -> RESTORE) and mirrors the body check in the test's validate_consensus.

The adaptive-frequency idle check counted artifacts for THIS cycle via
grep -c "\"cycle\":$loop_count" .../artifacts.jsonl
a bare substring match: cycle 1 also matched {"cycle":10}, {"cycle":11},
{"cycle":100} etc. So a low-numbered cycle never looked idle once higher
cycles existed, and the adaptive sleep never kicked in. Metric/perf
severity (idle-detection accuracy), not data loss.
Anchor the pattern on the JSON field terminator (,|}) and use ERE (-E)
so the alternation parses on both BSD and GNU grep:
grep -Ec "\"cycle\":$loop_count(,|})" ...
Proven red->green: cycle 1 reported 4 (true 1) before, 1 after; cycle 10
reported 2 (true 1) before, 1 after. Absent cycle reads 0.

reverted. run-all.sh auto-discovers it; full gate 4/4 green (5 new cases).

Summary
A bundle of reliability hardening fixes for the autonomous loop (
auto-loop.sh), each verified by a runnable test. The full suite is 20 assertions across 2 test files, all green from a clean checkout (runbash tests/run-all.sh).These address real failure modes that corrupt cross-cycle state or hide why a cycle failed.
What & why
subtype:success,is_error:true) but still wrote a valid consensus used to wipe the relay baton — the next cycle started from a blank slate and lost all cross-cycle context.validate_consensusis now the gate; a valid consensus is kept.--historyand--dashboard-..bak), a failed cycle printed "Consensus restored from backup" while leaving the invalid file in place.restore_consensusnow returns a distinct status and warns when there's no backup.cycle-history.jsonlC:\Users\foo) or a trailing\emitted an invalid JSON escape. Since every--history/--dashboard/--costsread doesjq -sover the whole file, one bad line returned nothing and killed the entire dashboard. The writer now escapes backslash first (order matters), collapses control chars, and self-checks each record withjq -ebefore append — falling back to a guaranteed-valid minimal record if any field ever breaks JSON.tests/run-all.shtests/test-*.sh, propagates failure, CI-ready.See
CHANGELOG.mdfor the user-facing breakdown.Verification
Each test extracts the actual shipped function from
auto-loop.sh(not a hand-maintained mirror), so it fails loudly if the function moves or its contract changes.Notes
