# R14: Trusted quiet suppression and input/output wake
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/2026-10-27T14-23-58.419Z-before-R14`. After run: `/tmp/lead-24640-r1/capture/2026-10-27T14-23-57.257Z-after-R14`.
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.
The real native protocol is transparently logged. After two stable snapshots, the next process-table request is about 30s later. Input invalidates the quiet mark; later output is written independently to the owned PTY, invalidating quiet without terminal.write.
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.

## Additional idle fallback contrast
Both use failing native helpers and an idle shell with no foreground child. Three shared fallback queries occur with approximately 2s/4s failure gaps, instead of native quiet suppression. The complete additional RPC/shim/server transcript and exact scripts are appended to each R14 transcript.

## Behaviour difference
Same quiet refresh and wake
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.
