LOCKED — PM Let-It-Run N=400 Phase B Execution

Date: 2026-04-24 (evening, post-kickoff) Ratified by: Marko Marković (verbatim-implicit via accept of PM recommendation) PM: claude-opus-4-7 (Cowork) Context: N=400 runner kicked (PID 647664, nohup-detached), first instance successful, projected 24h wall-clock (vs brief 180-min projection)

Odluka

LET IT RUN. 180-min wall-clock u Phase 2 brief bio je PM projection greška, ne hard halt trigger. Budget-side halts ($28 soft, $30 hard) su real triggers; time-side nije specifikovano kao trigger. Runner nastavlja do completion ili budget-side halt.

PM brief error acknowledgment

Original Phase 2 brief §5 specifikovao "Wall-clock cap: 180 min" bez eksplicitne halt trigger specifikacije. To je bilo wall-clock projekcija bazirana na optimističkoj racunici bez proper aritmetike:

Pretpostavljeno: 400 instances total
Actual: 2000 total evals (400 per cell × 5 cells)
Pretpostavljeno: parallel execution ili aggressive concurrency
Actual per v5/v6 §7: concurrency=1, sequential cells, sequential instances
Pretpostavljeno: ~90-150 min wall-clock
Actual: ~24-28h wall-clock (~45s per instance × 2000 = 25h)

CC-1 korektno surfirao ambiguity na kickoff-u i zatražio PM adjudication. PM odlučio: projekcija nije binding trigger; budget-side halts ostaju authoritative constraint.

Zašto LET IT RUN je correct choice

SOTA benchmark wall-clock parity: 24h je normalno za production SOTA runs čak i kod top labs. Naš concurrency=1 sequential setup je disciplinovan pre-reg choice, ne inefficiency.
Kill bi izgubio in-progress work: no-context cell već u execution, prvi instance uspešan (Qwen 13.4s, $0.002). Zero benefit od early kill.
Concurrency povećanje = §5.2 scope deviation: raising concurrency mid-run bi zahtevalo v7 re-pre-registration. Ne vredi to komplikovati radi wall-clock convenience.
Marko "pravi sota rezultat" direktiva: eksplicitno prioritetizuje thesis integrity nad wall-clock convenience. 24h čekanja je manja cena nego nov adjudication ciklus.
Budget-side gate je binding: $28 soft halt + $30 hard halt ostaju aktivni kroz ceo run. Projected $20-25 drži nas komfortno pod cap.

Current run state

Parent launcher PID: 647664 (nohup wrapper, exited after detach — normal nohup behavior)
Actual runner PID: 71020 (node process, holds runner-lock, live process — this is the PID to check for liveness)
Runner lock: benchmarks/results/.benchmark-runner.lock (pid=71020)
Current cell (at kickoff): no-context (1/5)
Output: benchmarks/results/no-context-locomo-2026-04-24T16-29-14-400Z.jsonl (live write)
Log: tmp/stage3-n400-v6-run.log
LiteLLM proxy: http://localhost:4000 (55 aliases, v6 additions live)
Session persistence: runner survives this chat session close

Monitoring PID lesson (2026-04-24 false-alarm debrief): CC-1 halt ping pomenuo dva PID-a. 647664 je launcher wrapper koji exit-uje odmah posle nohup detach-a (normal behavior); actual runner child je 71020 koji drži runner-lock i obavlja execution. Buduće liveness check mora koristiti PID iz runner-lock file-a, ne launcher PID iz halt ping-a.

Monitoring cadence (Marko-side)

Svakih 4-6h tokom sledećih ~24-28h:

Progress check (safe, non-invasive) — PowerShell on Windows:

Get-Process -Id 71020 -ErrorAction SilentlyContinue
Get-Content tmp\stage3-n400-v6-run.log -Tail 20
Get-ChildItem benchmarks\results\*-locomo-2026-04-24T16*.jsonl | ForEach-Object { "$($_.Name): $((Get-Content $_.FullName | Measure-Object -Line).Lines) / 400" }

Or combined one-liner:

Write-Host "=== PID ===" ; Get-Process -Id 71020 -ErrorAction SilentlyContinue ; Write-Host "`n=== PROGRESS ===" ; Get-ChildItem benchmarks\results\*locomo-2026-04-24T16*.jsonl | ForEach-Object { "$($_.Name): $((Get-Content $_.FullName | Measure-Object -Line).Lines) / 400" } ; Write-Host "`n=== LOG TAIL ===" ; Get-Content tmp\stage3-n400-v6-run.log -Tail 10

Projected cell completion (approximate, assumes no unexpected delays):

no-context: ~21:00 CET 2026-04-24 (tonight)
oracle-context: ~02:00 CET 2026-04-25 (overnight)
full-context: ~07:00 CET 2026-04-25 (morning)
retrieval: ~12:00 CET 2026-04-25 (midday)
agentic: ~17:00 CET 2026-04-25 (late afternoon)

Runner kicks post-execution analysis + commits post-all-cells-complete.

Kill triggers (flag back to PM)

Marko pinguje PM sa log excerpt za adjudication ako:

Budget halt: log shows "$28" threshold hit ili "BUDGET_HALT" token
Streak halt: §7.2 "3 consecutive subject failures" detected
Cost projection exceeds: cumulative $ > $25 pre completion agentic cell
Cell stalls: any cell shows no progress >8h (potential openrouter cascade or MiniMax outage)
Log errors cascade: repeated "ERROR" tokens bez successful recovery
Strategic abort: Marko-level decision iz bilo kog razloga

U većini slučajeva PM adjudication odlučuje između (a) resume with mitigation, (b) clean restart sa lessons, (c) abort + scope reduce.

Completion protocol

Kada svih 5 cells complete (sutra popodne):

Marko resume session sa PM (this thread ili new)
CC-1 resumed from same worktree
CC-1 pravi 4 Phase 2 deliverables:
- stage3-n400-v6-results.jsonl (merged all cells)
- stage3-n400-v6-analysis.md (Fisher one-sided H1 test + per-cell + agentic diagnostic)
- stage3-n400-v6-operational-report.md (metrics)
- stage3-n400-v6-memo.md (≤300 words)
