From b7bd1a48185e759fbcf40c63896d717bf5047ca3 Mon Sep 17 00:00:00 2001 From: Pranit Date: Mon, 31 Aug 2026 16:27:44 -0400 Subject: [PATCH 01/21] Speed up terminal menus and full transcript Move skill discovery and transcript preparation off the input and render paths. Reuse indexed snapshots for menu queries and full transcript viewports. Read authentication presence without loading stored secrets. Add a ReleaseSafe percentile gate for the affected surfaces. --- .github/workflows/bench.yml | 18 + build.zig | 4 + scripts/pgso/corpus.json | 1 + src/acp/server.zig | 6 +- src/core/app/app_auth_runtime.zig | 14 +- src/core/app/app_bootstrap_runtime.zig | 16 +- src/core/app/app_commands.zig | 17 +- src/core/app/app_input_runtime.zig | 9 +- src/core/app/app_render_runtime.zig | 8 +- src/core/app/input_subagent_runtime.zig | 6 +- src/core/auth/credentials.zig | 42 +- src/core/hosts/host.zig | 22 + src/core/hosts/native_keychain.zig | 47 ++ src/core/hosts/native_secret_store.zig | 25 + src/core/skills/skill_runtime.zig | 595 ++++++++++++++++++- src/main.zig | 43 +- src/ui/footer/render_input.zig | 32 + src/ui/footer/skills_menu_presentation.zig | 88 ++- src/ui/full_transcript_screen.zig | 46 +- src/ui/transcript/full_transcript_worker.zig | 61 +- src/ui/transcript/painter.zig | 63 +- src/ui/transcript/runtime.zig | 174 +++++- src/ui/transcript/source_preparation.zig | 35 ++ tests/e2e/ci-shard-weights.json | 1 + tests/e2e/tui-full-transcript-brutal.test.ts | 4 +- tests/e2e/tui-performance.test.ts | 402 +++++++++++++ 26 files changed, 1653 insertions(+), 126 deletions(-) create mode 100644 tests/e2e/tui-performance.test.ts diff --git a/.github/workflows/bench.yml b/.github/workflows/bench.yml index fa3902ea9..a36ce15b4 100644 --- a/.github/workflows/bench.yml +++ b/.github/workflows/bench.yml @@ -44,3 +44,21 @@ jobs: for run in 1 2 3;
