Format loosely follows ## [Unreleased] ### Added +- **Operator-friction scan — `scripts/friction.py`.** Deterministic port of canary's `lib/sessions/friction.ts` (that repository is now a frozen paper archive; this was its one capability Modore did not already have). Flags the user turns where the operator pushed back on agent behaviour, across nine categories — wrong-action, no-research-assertion, stalling-approval, rule-contamination, over-orchestration-token, stale-repetition, verbosity, tone-attitude, other-ai-friction — at severity 1-3. Keyword and tone matching only, no model in the judgment path. Claude Code and Codex sessions are discovered through scree's own collectors rather than a second traversal; Gemini CLI chats (`~/.gemini/tmp/*/chats`, joined to a workspace through the project registry) and Claude Desktop local-agent sessions are added because scree does not traverse either — its Gemini collector reads only the project registry, and it has no Claude Desktop collector. Content contract: user-authored turns only, quotes capped at 200 characters and masked by default (`--raw-quotes` opts out), nothing written. `--json` serves the structured report. First live run over a 30-day window: 200 sessions, 3,563 user turns, 430 findings (rage 247 / irritation 60 / correction 123). +- **Read-only MCP surface — `scripts/mcp_server.py`.** A zero-dependency stdio JSON-RPC server exposing three tools: `scree_report` (join, retention forecast, sole-copy and orphan verdicts, by section), `friction_scan` (the taxonomy above, filterable by store/category/minimum severity), and `system_scan_summary` (the storage and security scan result already on disk, with its age). Each tool runs `scree.py --json` or `friction.py --json` and forwards the output, so no judgment is reimplemented and the CLI, the Mac app, and the MCP surface cannot disagree. Cleanup, deletion, and scan execution are deliberately not exposed — Modore's destructive path is gated on an on-screen human approval, and an agent-reachable bypass would void it; pinned by a test that exercises every tool and asserts the only processes ever spawned are the two judgment scripts. The read-only contract is enforced where tools are registered, ported from AirMCP's own Swift MCP server (`IOSPreviewContract`): a tool is reachable only if it is on an explicit name allowlist and annotated read-only and non-destructive, so one added without a deliberate edit fails closed rather than being merely unlisted. All results are fenced as untrusted machine-derived data. - **scree lineage: what the sessions remember versus what the disk still holds.** Every work path appearing in session records is classified alive+git / alive+plain / vanished, using existence and a `.git` presence check only; macOS case-variant ghosts (the same path recorded under different casings) are merged by casefold and reported once with their spellings. First live run: 422 paths — 118 alive git repos, 189 alive plain directories, 115 vanished (session records their only trace), 4 case ghosts. Consumers such as balance's lineup-gap diff read `--json .lineage`; scree itself reports universal facts only. - **Stray primary-checkout judgment (scree).** Agent sessions can leave a repo's *main checkout* parked on a non-default branch with unmerged work — the same unique-work risk as an orphaned worktree, but invisible to worktree listing. `collect_worktrees` now judges the primary checkout of every repo that hosts agent worktrees: a non-main/master branch is reported as `stray_checkout` with the same protected-versus-rebuildable rules, and the report lists each one with its branch and unpushed count. First live run found 11 stranded checkouts, three of them carrying unpushed unique commits. diff --git a/README.md b/README.md index 8c91118..959a587 100644 --- a/README.md +++ b/README.md @@ -28,6 +28,36 @@ python3 scripts/scree.py preserve # masked single-session export - **Orphans & lineage** — sessions pointing at vanished workspaces (`orphan_basis: path_missing`), and every remembered work path classified alive+git / alive+plain / vanished, with macOS case-variant ghosts merged. - **Contract** — leading JSONL lines are decoded in memory but message content is never retained or emitted; nested transcripts are attributed by `stat()` without being opened; pinned by tests. `preserve` is the single deliberate exception: one caller-named file, mask-by-default (`--raw` opts out), no bulk export. +**friction**, scree's sibling, reads the same four session stores for the opposite question — not what the agents left behind, but where the operator stopped them: + +```bash +python3 scripts/friction.py # 9-category pushback taxonomy · severity 1-3 +python3 scripts/friction.py scan --json --source codex # structured output, one store +``` + +- **Nine categories** — wrong-action, no-research-assertion, stalling-approval, rule-contamination, over-orchestration-token, stale-repetition, verbosity, tone-attitude, other-ai-friction, at severity 1 (mild correction) / 2 (clear irritation) / 3 (rage).

A fan that will not stop, CPU/GPU load while idle, an unknown process, a strange network connection, disk space vanishing overnight. Generic scanners detect but do not explain — and on a Korean banking/government PC they cry wolf over IPinside, nProtect, MagicLine and the rest of the mandated plugin set until users either panic-uninstall critical software or learn to ignore every warning. Modore is the second opinion: it joins process, network, autorun, security, and storage signals, checks miner-like runtime patterns, recognizes the Korean plugin set with a locale-aware whitelist, and explains every finding in plain Korean, English, or Japanese with a 🟢🟡🔴 verdict.
