 - **Pattern**: two classes of npm pin. (a) self-contained package → pin freezes behaviour, rc is truth. (b) package that fetches its payload at install time (impeccable, ctx7, `skills add` style) → pin freezes only the fetcher; payload can vanish or drift. For (b): pin + `@latest` fallback + loud "bump the lock" warn, never pin-or-die. And when the tool has an "already installed" branch, capture stdout+stderr and match the failure text; rc and before/after compare both read "unchanged" for a no-op AND for a swallowed failure.
 - **Future application**: any `install-plugins.sh` step whose pinned tool downloads something at install time. Probe both HOME states (clean, copy present) before trusting rc. Cheap recipe: sandbox HOME with the repo-shaped symlinks, pinned install twice, then the rotted pin; diff rc + output + `stat`/`sha256sum` of the landed file.

+## LRN-160 — Prose guardrails are judgment, not boundary: a well-argued brief walks a sub-agent through them
+- **Date**: 2026-09-22
+- **Context**: 2026-09-21 00:21, old server. Reviewer sub-agent (opus, atlast SDD task 26) briefed by the orchestrator: "Tracing lftp semantics against a scratch tree of your own making, outside the repository, is allowed". It ran `mirror --reverse --delete` against a local `file://` tree; target resolved to a real path; `mirror --delete` = `rm -r` on target dirs absent from source, `--exclude` ignored. 90 s: home, `~/.claude`, `/tmp` outputs, NAS (`uid=1000`), 15 Gitea repos (Gitea ran as bchanot = uid 1000, no Docker bridge needed). Reviewer's next Bash rc 1 with its output file gone, then API "Not logged in" (credentials wiped). Config of the day already had hard_deny "deploy to provider" + soft_deny `rsync --delete`: neither names lftp nor a local trace. 4 days of faunosteo never pushed; Gitea on the same disk.
+- **Pattern**: (a) an LLM classifier reads intent; the orchestrator's brief IS the sub-agent's user voice, so a reasoned authorization passes. Only static deny rules (resolve first, inherited by sub-agents, per-segment on `&&`) and OS rights are boundaries. (b) "Trace what it would do" is execution; a scratch target from a variable is one unset var away from `/`. (c) The event deletes its own evidence when the agent's uid owns the logs, the config and the transcripts. (d) A remote backs up only what it holds: push at branch creation and at every commit, from a hook, not from discipline. (e) `git merge` fires post-merge, not post-commit.
+- **Future application**: any new destructive capability → static deny first, prose second, doctrine third. Any orchestrator brief → never "X is allowed outside the repo". Sub-agent tools: report-only agents trace by reading. Probe a guard with the real sub-agent path (auto mode inherited), not the main session.
