## Execution log
- Executor: in-session Agent (haiku). Attempts: 1. Fix rounds: 0.
- Orchestrator re-ran Verification on a fresh port: `Content-Encoding: br`, ETag, `Vary`, 304 on If-None-Match, index stamped (`ytp-build` 1), sw.js gzip + original no-store `Cache-Control`, BUILD_TAG injected (0 placeholders), SPA fallback 200, 52 frontend tests pass. app.js 426 244 -> 93 759 bytes.
- Executor Findings (verbatim): All 5 verification tests pass. All unit tests pass. Changes follow the plan exactly: added brotli/zlib imports, implemented compressedEntry/sendCompressed helpers with ETag and dual-compression support (br preferred, fallback to gzip), updated indexHtml and sw.js handlers to use sendCompressed, and added middleware for compressing all text files under ./public. Cache-Control headers preserved exactly as specified. No changes made to sw.js, sw-update.js, or computeBuildTag.
- Orchestrator note: the executor left a background server on port 3999; killed. Cosmetic: the helper block sits between the old indexHtml comment and `let _indexSource`.
