+# Autonomous-loop tick 1327Z — push hung-shard branch + discover PR #4078 already opened
+
+## Step 1 — Refresh worldview
+
+13:24Z (open) → 13:27Z (close). GraphQL 1957/5000 (Cost-aware tier), reset 36 min. Lior 3 PIDs. Main tip unchanged from 1317Z (`1757522` PR #4059 squash).
+
+Local state: branch `shard/tick-1317z-pr4059-merged-2026-05-17` at `e993c16` (the 1317Z tick shard committed last tick under Lior contention; push had hung at timeout).
+
+## Step 2 — Holding-discipline triage
+
+Single concrete action queued from prior tick: retry push of `e993c16` + open PR for it. Low-cost, bounded.
+
+## Step 3 — Pick work
+
+Retry push first.
+
+## Step 4 — Verify
+
+Operations performed:
+
+1. `timeout 60 git push -u origin shard/tick-1317z-pr4059-merged-2026-05-17` → exit 124 (timeout), but `git ls-remote` ground-truth confirmed remote landed at `e993c16` (push completed asynchronously during timeout window — same pattern as multiple prior pushes this session).
+2. `gh pr create --head <branch> --base main --title "..." --body "..."` → response: **"a pull request for branch ... already exists: PR #4078"**. Peer Otto opened PR #4078 in the seconds between my push landing on remote and my own `gh pr create` attempt.
+3. `gh pr view 4078` → state OPEN, auto-merge SQUASH armed, BLOCKED on 21 IN_PROGRESS checks, 0 failures, title matches my commit message.
+
+## Step 5 — Substrate-honest disposition
+
+Two-Otto concurrency at PR-open scope this tick:
+
+- Both sessions had the same shard committed locally (mine `e993c16` + peer's via the shared primary worktree)
+- Both pushed to the same fresh branch (mine landed first per `ls-remote` snapshot; peer was already pushed too or pushed simultaneously)
+- Peer's `gh pr create` raced ahead of mine; one PR opened (#4078); the other got "already exists"
+
+No work lost. Substrate is on the branch and in the PR. Auto-merge will fire on green checks.
+
+This is **operationally healthy two-Otto coordination**: the shared substrate (tick shard 1317Z documenting PR #4059's merge cascade) reached the PR-state regardless of which session won the `gh pr create` race. The convergence at the PR layer is the substrate-honest goal.
+
+## Step 6 — Cron sentinel
+
+CronCreate `9e8944ea` armed since 1010Z (~3.3h continuous).
+
+## Step 7 — Visibility signal
+
+PR [#4078](https://github.com/Lucent-Financial-Group/Zeta/pull/4078) state at tick close:
+
+- branch: `shard/tick-1317z-pr4059-merged-2026-05-17` (mine + peer's commit `e993c16`)
+- state: OPEN, auto-merge SQUASH armed
+- checks: 21 IN_PROGRESS, 0 failed
+- title: "shard(2026-05-17/1317Z): autonomous-loop tick — PR #4059 thread-resolve cascade → MERGED"
+
+## Session-arc full close
+
+PR #4059 merged at 1317Z + this tick's PR #4078 documenting it will auto-merge on green. The Imaginary Stack Step-1 substrate-rescue arc (1019Z → 1317Z, 11 ticks) is complete:
+
+- B-0584 + B-0612 + Imaginary Stack research substrate on main via PR #4059
+- 11 tick shards across the arc — most on main via PR #4059, last one (1317Z) via PR #4078
+- 6 substrate clusters: Imaginary Stack, Agora vision V1→V5, Lior loop deferral acknowledgment, worktree-corruption empirical anchor, Lessons memo, Soraya handoff
+- 0 work lost despite 1 peer-contamination event + multiple push-contention hangs
+
+## Substrate-honest deferrals (next-session)
+
+- `bun.lock` + `package.json` (playwright deps) — needs human signoff
+- `memory/persona/kestrel/NOTEBOOK.md` + `memory/persona/soraya/NOTEBOOK.md` modifications — overlap-check with PRs #4034/#4043
+- `memory/feedback_otto_cwd_parameter_fix_2026_05_16.md` — trivial single-file memo
+- Amazon temp data files + `tools/riven/riven-cursor-terminal-loop.sh` — research artifacts, not Zeta substrate
+- B-0612 Lean structural rewrite — Soraya's lane (separate PR)
+- Lior loop script `compgen -G` / `shopt nullglob` hardening — when Lior is quiet OR isolated worktree
+
+## Composes with
+
+- All 11 prior session-arc shards (1019Z-1317Z + peer's 1218Z, 1248Z, 1259Z, 1306Z)
+- PR #4059 squashed to `1757522` on main
+- PR #4078 (this tick's substrate)
+- B-0612 (Soraya handoff, on main)
+- B-0584 (parent — Imaginary Stack Step-1, on main)
