Task 5: repo is public, so parity fixtures are trimmed to the managed subset and username-sanitized. Task 4: apply() takes home and creates backup/lock dirs itself. Task 9: setup.ps1 cds to the repo root. Confidence now 92-95% across all tasks.

fix(setup): reject non-dict JSON in diff(), dedupe hook-group builder Review findings on engine.py: 1. diff() raised TypeError on valid-but-non-dict settings.json/.claude.json content (5, null, [1,2,3], "text") because merge_settings/patch_mcp_entry both do dict(existing). _load_json_or_drift now validates isinstance(..., dict) and treats non-dict JSON the same as malformed JSON: one drift line, no exception. 2. render() and merge_settings()'s ADD pass built the same per-event matcher-group structure twice. Factored into _canonical_hook_groups(), called from both, so they cannot drift apart from each other.

Serializes concurrent apply() calls via a lock file (60s stale timeout) and retries once if ~/.claude.json is rewritten by Claude Code itself between the pre-write read and the atomic write (spec concern 3). Malformed JSON in a target file produces a warning and leaves that file untouched. _backup/_atomic_write are duplicated from cli/install_hooks.py rather than imported, since that module becomes a shim over this engine in a later task and must not become a dependency of it. install_skills() ports install_skill_symlinks, parameterized by target dir + repo root and extended to loop MANAGED_SKILLS. Also vendors the start-better-memory-ui skill into .claude/skills/ (it previously lived only in ~/.claude/skills/) and rewrites its machine-absolute paths to repo-relative wording so it can serve as the symlink source alongside the other two managed skills.

The remainder collapses into a one-line `### Index (not expanded - retrieve on demand)` section plus a footer affordance pointing at `memory.retrieve` / `memory.retrieve_observations`. Semantic memory ids in the rendered output are the full ids (not truncated), each stamped with an age suffix (`(Nd old)`). Setting `BETTER_MEMORY_BOOTSTRAP_TOP_N=0` disables slimming and renders everything in full. - **`deferred`**. SessionStart renders only general-scope semantic memories in full, plus a single index line ("better-memory knows N reflections + M semantic memories for this project; relevant ones will surface as you work - or ask via memory_retrieve with a task query"). Project-scoped semantic memories and all reflections are not dumped at session start; they surface exclusively through the contextual channel below, or on demand via `memory.retrieve` / `memory.retrieve_observations`. -**CLAUDE.md drift sentinel (SessionStart only).** After bootstrap renders, `hooks/session_bootstrap.py` best-effort-scans the user's `~/.claude/CLAUDE.md` for parameter tokens documented next to a better-memory tool name and flags any the live MCP tool schema does not recognize (`better_memory/hooks/_claude_md_sentinel.py`; schema built from `mcp/tools.py`, so it tracks future tool changes automatically). The accepted-token set per tool is schema-derived, not just its property names: enum *values* (e.g. `memory_retrieve`'s `polarity` values `do` / `dont` / `neutral`) count as valid tokens too, since real CLAUDE.md prose legitimately backtick-quotes them next to the tool name -- this avoids false-positiving on documented return shapes. At most one warning line is appended to bootstrap's `additionalContext` per session; the check is silent when clean, and any exception is swallowed, so the sentinel can never block or degrade injection. It runs only on the SessionStart bootstrap path, not on the contextual channel. Alongside the sentinel, `better_memory/skills/CLAUDE.snippet.md` was rewritten to behavioural instructions only ("pass a task-describing query when you begin a task", "credit with evidence") and never enumerates parameter names or types, so the canonical snippet itself can no longer drift into the failure mode the sentinel exists to catch. +**CLAUDE.md drift sentinel — retired.** SessionStart no longer runs a standalone sentinel that scanned `~/.claude/CLAUDE.md` for stale tool-parameter references (`better_memory/hooks/_claude_md_sentinel.py`, deleted). See [Self-managing wiring](#self-managing-wiring) above: the retrieve/reinforce/synthesize/record protocol text is now a managed block (`manifest.CLAUDE_MD_BLOCK`) that `better-memory setup` / `doctor --fix` / the session-start autocheck (`better_memory.setup.autocheck.maybe_repair`, wired into `hooks/session_bootstrap.py`) keep byte-identical to the canonical text, so drift is repaired outright rather than merely flagged. `better_memory/skills/CLAUDE.snippet.md` (used for non-Claude-Code MCP integrations) remains behavioural instructions only ("pass a task-describing query when you begin a task", "credit with evidence") and never enumerates parameter names or types, so it can't drift the way the retired sentinel used to detect. **Contextual injection (UserPromptSubmit / PreToolUse).** The `contextual_inject` hook (`better_memory/hooks/contextual_inject.py`) scores the curated memory set (semantic + reflections) against the current prompt (UserPromptSubmit, fires on every prompt) or tool name + input (PreToolUse, matcher now unscoped -- every tool call, not a fixed allowlist) via `retrieve_relevant` (`better_memory/services/relevant.py`), a three-leg evidence-gated scorer: diff --git a/website/configuration.md b/website/configuration.md index 7c4f5c1..9b30930 100644 --- a/website/configuration.md +++ b/website/configuration.md @@ -7,6 +7,7 @@ One environment variable roots the runtime filesystem layout.
