From e03168a797cf3b998a521b98565eec40f23a52d9 Mon Sep 17 00:00:00 2001 From: Aleksandar Grbic Date: Sat, 26 Sep 2026 21:36:29 +0200 Subject: [PATCH] =?UTF-8?q?feat(research):=20multi-day=20runs=20=E2=80=94?= =?UTF-8?q?=20no=20turn=20cap=20without=20a=20gate,=20mid-send=20saves,=20?= =?UTF-8?q?dedup,=20smaller=20images,=20append=20tool?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lessons from a 5h+/1,095-thread live crawl: - turn cap: sessions with no live gate (research/notes/chat) run uncapped; gated builds and plan mode keep the 1000-turn backstop; TSFORGE_MAX_TURNS overrides (0 = unlimited). Re-evaluated each turn so a waking gate applies. - the REPL saves the session on every checkpoint (every 40 turns), so a crash or reboot mid-send no longer loses the conversation for --continue - TTSR stream rules (TypeScript: no-as-cast…) are off while build mode is suppressed — they fired on prose about guitar wiring - reddit_thread refuses threads already logged in sources.md unless force; within a session any chunk is served from cache. New reddit_mark_read logs threads covered another way (earlier crawls). The run had 64 duplicates. - images: Reddit's <=1080px rendition instead of originals (~5x smaller; the run saved 1.3 GB), 20 post + 10 comment images per thread - append tool: add lines to a data file (jsonl/csv/log) without an edit anchor; JSONL validated, code/config refused.
