## About

# gleanin

Rules from past failures. Apply every session.

### Credentialed Write Gate

**Rule:**
1. Before writing with ambient credentials, verify scope (` whoami`, `config view`).
2. Exact-match created resource name against intent.
3. On mismatch, roll back immediately.
4. Never mark done when acceptance probe failed.

**Check:** `grep -c "inoffensif\|harmless\|can delete\|not needed"` in session transcript — zero for any failed write.

### Delegation Preflight

**Rule:**
1. Scan delegation payload against delegate's Known Limitations first.
2. Verify with `git diff`, not the delegate's `[OK]` lines.
3. On partial landing, name the limitation before hand-editing.
4. Structural integrity check every delegate-touched file.

**Check:** `git diff --stat HEAD` after delegation — changed file count must match expected.

### Device First Check

**Rule:**
1. Search filesystem (`find`, `grep`, `ls`) before asking the user.
2. `curl -sI` before declaring anything "not deployed."
3. Syntax check + tail check before committing.

**Check:** `grep -c "AskUserQuestion\|curl.*not.find\|edit.*then.*ask"` in session transcript — near zero with this rule.

### Reference First Porting

**Rule:**
1. Read the reference before editing any formula or algorithm.
2. Cite `file:line` per edit.
3. Apply supplied values verbatim before re-derivation.

**Check:** `grep -rn "TODO\|FIXME\|guess\|maybe" ` — zero after a port.
