- Switch model to grok-4.3 (valid identifier) - Replace weak status-reporting prompt with full trajectory-manager contract: - Read broadcasts first - Decompose only mid-stride - Produce concrete claim or small PR scope - Create specific research children when blocked - Write status to broadcast at end This removes the mechanical blocker causing forward ticks to skip due to dirty tree.

Removing .cursor/bin/riven-loop-tick.ts breaks the currently documented and scripted Riven runtime path: operators are instructed to launch and hot-swap that exact file (docs/operations/riven-tier1-launchd-hot-swap-checklist.md:38-43,77-100), the rotation table still declares it as the background loop (docs/ROTATION-PROTOCOL.md:17), and the gate prompt points to it as the cadence implementation (.cursor/riven-loop-tick-prompt.md:6). On a fresh control clone (or any rollout following these docs), launchd/program arguments and checklist commands will hit ENOENT, so the Riven heartbeat/forward loop cannot be started or updated.

…2nd consecutive 0 stuck procs) + Lior-lane 54/60 steady (#4894) Continues 2026-05-24 1607Z→1608Z→1804Z→1902Z→2033Z→2206Z + 2026-05-25 0008Z lineage. Substantive visibility shard documenting: 1. 15th dotgit anchor — 2nd consecutive 0-stuck-proc reading (0008Z was 1st clean after 13-anchor saturation arc). First discrimination data point for the A/B posture default-to-both held at 0008Z; A (genuine recovery) gains evidence but is not yet sufficient for closure per the 12th-anchor empirical precedent. 2. Lior-lane fleet 54/60 = 90% (steady from 0008Z's 90.6%). The 6 non- lior-* PRs (4883/4885/4887/4888/4890/4891) are byte-identical to 0008Z — static, awaiting separate disposition. Lior merged 4 own PRs in 34 min (#4863/#4862/#4892/#4893) confirming active driving. 3. Empirical FP-class check across 24 threads on 3 BLOCKED PRs (#4768/ #4781/#4786): 0% FP rate. Threads are substantive P0/P1 substrate- engineering findings (hardcoded paths, label/filename mismatch, broken bootout, persona-name-in-code, runtime-path-delete with broken doc refs) requiring Lior-side fixes, NOT bg-worker no-op resolution. The "FP-thread resolve" pattern from #4869/#4879 was scoped to specific markdown lint FPs; current open-PR thread surface is dominated by substantive findings. Per blocked-green-ci-investigate-threads.md + honor-those-that-came-before + no-directives + mechanical-authorization-check + human-audit-and-legal- risk-acceptance: cross-lane resolution at scale is not authorized; visibility shard + cron heartbeat IS the substrate-honest disposition.

Removing this file drops the executable that the repo still treats as Riven’s runtime entrypoint, so deployments that launch com.zeta.riven-loop against .cursor/bin/riven-loop-tick.ts will fail with a missing-script error and stop both heartbeat and 15-minute gate cycles. Fresh evidence in this commit’s tree is that the active prompts still point at this exact path (.cursor/riven-loop-tick-prompt.md:6, .cursor/riven-background-agent-prompt.md:6) and the hot-swap runbook still operates on it (docs/operations/riven-tier1-launchd-hot-swap-checklist.md:38-43).

| ### Observation | ||
| A series of "blob" pull requests were created, bundling multiple unrelated changes. This included backlog decomposition, PR preservation, and script modifications. Concurrently, another agent (Riven) was observed attempting to decompose these same PRs, leading to contention and duplicated effort. | ||
|
|
||
| ### Lesson | ||
| The one-artifact-one-PR rule is critical for maintaining a clean and efficient workflow. When this rule is violated, it creates confusion, wastes resources, and can lead to conflicts between agents. | ||
|
|
||
| ### Corrective Action |
| 1. A drift report was filed to the broadcast bus to alert other agents to the issue. | ||
| 2. This shadow lesson log entry was created to document the problem and the importance of the one-artifact-one-PR rule. | ||
| 3. The agent responsible for creating the blob PRs should be identified and reminded of the rule. | ||
| 4. A clear protocol for claiming and decomposing PRs should be established to prevent future contention. |

Deleting this file removes the only tracked Riven loop runner while repo-owned operational surfaces still target this exact path, so a control clone following those instructions cannot run or hot-swap the com.zeta.riven-loop cadence and will hit a missing-file failure. Fresh evidence beyond prior comments: docs/SAFE-AUTONOMOUS-ACTIONS.md:74 still enumerates .cursor/bin/riven-loop-tick.ts as the Riven autonomous-action script, and .cursor/riven-background-agent-prompt.md:6 still points maintainers to this entrypoint.
