From 9c1bcef29beb868e1c6d50c1e72f8b849358457c Mon Sep 17 00:00:00 2001 From: Brett <272292289+InfinitePortaldev@users.noreply.github.com> Date: Sat, 11 Jul 2026 23:16:43 -0600 Subject: [PATCH 1/9] Update detector spec tests to match the #129 threshold tuning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The tuning in #129 left the older detector spec tests behind — they still assume the stricter pre-tuning thresholds, so npm test fails on a fresh clone.

Selection takes candidates[0] within a category, so the general finding won purely on the order detectors run in. The per-anchor cooldown made it self-reinforcing rather than self-correcting: it keys on anchor_claim_id without regard to type, so emitting the general finding also blocked the specific one on that anchor. `echo_chamber` could not surface at all. `SUBSUMES` names the containment; `runAllDetectors` drops a general finding when a more specific one fired on the same anchor. Thresholds are untouched — Also fixes two defects #129 exposed in the same area: - `unchallenged_chain` fired on the unchallenged *suffix* of a challenged chain. The walk started from every node, so once the minimum length dropped 4→3 a suffix below the challenged pair became a candidate in its own right. It now starts only from maximal chains, matching its documented "anchors on the head" intent. - The "below threshold" / "below minimum length" fixtures hardcoded edge counts that #129's retuning turned into *at*-threshold cases, so they went green while testing nothing. They derive from REASONING_CONFIG now. Three fixtures were mislabeled: they seeded a user vibes claim backed by assistants with no pushback — a textbook echo chamber — and read as load-bearing only because of the ordering bug. They now use an assistant-authored anchor so they test what they claim to. Builds on #151, which fixes the same five failures by pinning the current behaviour and explicitly defers the real fix here. The two fixture sets conflict and should not both be merged as-is.

Buddy's `UserPromptSubmit` hook (now registered **synchronously** so the host folds its stdout into context — the installer upgrades older async registrations) re-injects the extraction instruction after `REASONING_CONFIG.REINJECT_AFTER_SILENT_TURNS` consecutive turns with no new claims, pulling the host back. Turn-driven and scoped to the current project session (not observe-seq, which freezes when the host goes silent); resets the moment a claim lands; gated behind a cheap status-file check so guard-mode-off users pay no DB cost. **No second LLM call, no API key, no outbound dependency.** A re-injection→recovery metric is recorded and surfaced in `buddy_doctor`. The same compiled hook is wired into both Claude Code (`~/.claude/settings.json`) and Codex (`~/.codex/hooks.json`), which route hook stdout to model context identically. Cursor/Copilot don't yet expose that contract, so on those hosts long-session silence is surfaced via the doctor's inert-guard warning rather than auto-recovered (the same handler drops in when they add the hook). Validated on real transcripts (3 projects × 2 Anthropic models, N=15, claims graded for substantiveness, controls valid incl. at 150k): with the instruction only in the distant system block, substantive extraction falls to ~0% at 150k (opus emits nothing at any length); re-injection in the shipped placement recovers it to 60–100%. Directional, not universal — see `src/lib/reasoning/DESIGN.md`. Note: an existing guard-mode-on companion's re-injection activates on the next `buddy_observe`/status write (when `guard_mode` is first mirrored into the status file) — a one-cycle self-heal, not a regression. The shared `buddy.db` now uses **WAL journaling** so the hook and MCP-server processes don't block each other; this adds `buddy.db-wal`/`buddy.db-shm` sidecar files — if you sync `~/.buddy` across machines, they must travel with the main DB. - **`convention` basis** (ported from slimemold) — for stipulated practice/policy by a named actor ("this project uses X", "agents must Y"), correct-by-fiat for its scope; distinct from `definition` (what a term *means*) and `vibes`/`research` (factual claims about a named thing). The observer instruction now carries slimemold's ordered basis decision tree and the v8 precision distinctions, so the host classifies claims more reliably. +### Fixed +- **`echo_chamber` could never surface; `grounded_premise_adopted` was shadowed** (#150, reported by @InfinitePortaldev) — some detectors are specializations of others: every `echo_chamber` case is also a `load_bearing_vibes` case (same anchor, plus a user speaker, assistant-only supports, and no pushback). Selection takes the first candidate in detector order, so the general finding always won; and because the per-anchor cooldown is type-agnostic, emitting it also blocked the specific finding on that anchor. `echo_chamber` was therefore unreachable in practice, not merely rare. `runAllDetectors` now drops a general finding when a more specific one fired on the same anchor (`SUBSUMES` in `types.ts`). Exposed by #129 lowering `LOAD_BEARING_MIN_DOWNSTREAM` 3→2 to match `ECHO_CHAMBER_MIN_SUPPORTS`; the thresholds are unchanged here, since they were tuned against real session density. +- **`unchallenged_chain` fired on the unchallenged *suffix* of a challenged chain** — the detector walked from every node, so a chain whose premise had been questioned still produced a finding anchored mid-chain, where no challenge sits between the remaining endpoints. It now starts only from maximal chains (nodes nothing else depends on), matching its documented "anchors on the head" intent. Also surfaced by #129's minimum-length 4→3. +- **Detector threshold tests no longer go green by accident** — the "does not fire below threshold" / "below minimum length" fixtures hardcoded edge counts that #129's retuning quietly turned into *at*-threshold cases, so they stopped testing anything.

Bun does not forward trailing arguments to `-e` scripts: inside the eval, `process.argv` is `['bun', '/[eval]']` and nothing more. `process.argv[1]` was therefore a constant path string, identical on every call, and the userId never reached the hash. Measured on master with Bun installed: 300 distinct userIds produced exactly one distinct stat vector. Rarity, species, eye and stats were the same for every rescued companion. Silent because the roll stayed perfectly deterministic — which is what the determinism test checks — and because the FNV-1a fallback path, used on machines without Bun, was always correct. The input now travels through the environment instead of argv, preserving the no-string-interpolation property that argv was chosen for. After: 200/200 distinct, still deterministic per userId. Already-rescued companions keep their stored bones, so no migration is needed, but every existing rescue was a clone of the same roll. The existing test compared two userIds, which reads as an unlucky fixture precisely when the bug is total. Replaced with a 40-id spread assertion. Not covered by any open PR — #152 and #153 fix the other fresh-clone failures.
