From 7d1d9e3b7da2a79620925a8a57513dfe561d736d Mon Sep 17 00:00:00 2001 From: Ashish-dwi99 Date: Tue, 21 Apr 2026 17:16:12 +0530 Subject: [PATCH 1/3] Add gstack parser package + test fixture Pure parsers for gstack's four memory surfaces (learnings.jsonl, timeline.jsonl, -reviews.jsonl, checkpoints/*.md) plus a sealed fixture that seeds a realistic projects// tree and 7 deterministic tests exercising backfill, tail-ingest, idempotency, checkpoint sectioning, uninstall, graceful skip when gstack is absent, and injection-safe refusal. Parsers reuse gstack's own prompt-injection denylist so we never ingest what gstack itself would reject, and preserve unknown fields on a `raw` passthrough so future schema drift doesn't silently discard data.

charset=UTF-8 Content-Transfer-Encoding: 8bit dhee/adapters/gstack.py is the read-only ingestor that turns gstack's siloed ~/.gstack/projects// memory into atoms on Dhee's `remember` pipeline. Per-project cursor manifest at $DHEE_DATA_DIR/gstack_manifest.json (byte offsets for JSONL, mtime+size for markdown) makes backfill and tail-ingest idempotent, handles truncation/partial-write cases, and never mutates gstack files. dhee/harness/install.py grows `_install_gstack` / `_disable_gstack` / `_status_gstack` mirroring the existing Claude Code + Codex pattern. Feature-detected: a missing ~/.claude/skills/gstack/VERSION yields a clean "skipped" result and leaves the config flag off. dhee/hooks/claude_code/__main__.py calls tail_ingest() on SessionStart and Stop — no-op unless the user has explicitly run `dhee install gstack`. Errors are swallowed end-to-end; session hooks never block.
