# R06: 5s shared fallback, 20 terminals
Before [e9236274a3](https://git.cafe/pingdotgg/t3code/commit/e9236274a3a6e0c731a7df4092db1e686f039068); after [63e44670dd](https://git.cafe/pingdotgg/t3code/commit/63e44670dd1d222cf63619d5e02415f2a9fd3bc2).
Before run: `/tmp/lead-24640-r1/capture/2026-10-27T14-33-18.684Z-before-R06`. After run: `/tmp/lead-24640-r1/capture/2026-10-27T14-33-17.500Z-after-R06`.
Environment: fs-31 Linux x86_64, Node v26.12.1; no viewport/theme/DPR/font scaling. Fresh per-run app databases. Same RPC fixture on each side. Native sidecars compiled with isolated Rust 1.99.1 where used.
A labelled nonzero seeding phase prevents partial candidate publication while all 20 foreground children are started. The measured shared-slow phase starts only after all 20 readiness tokens. After publishes all 20 from its first slow snapshot, before pacing; before times out. The full next-query gap is recorded.
Wrapper timings exclude Python startup and stream drain. Acquisition timings use the real terminal.posixProcessTableSnapshot trace span. An idle gap is END→next START, never start-to-start. Before delay=min(1000×2^failureCount,60000)ms; after delay=min(max(1000×2^failureCount,4×measured fallback acquisition),60000)ms. Native-failed production ticks increment failureCount even when fallback succeeds; successful absent-supplier harness ticks reset it. Native requests and terminal processing can add overhead.

## Behaviour difference
Timeout → all 20 shared results, ~20s idle
Raw UTC/monotonic RPC, query, signal, metadata, warnings, and cleanup records are in the paired transcripts. PID, randomly generated script terminal suffix, database path, UTC, sequence batching, and scheduler jitter naturally vary between fresh runs. No visual comparison is applicable.
