## Session Summary

Added a fleet-wide error-logging rule to the core operating manual. Mike requested that
when a session hits errors while executing tasks, the failure details be recorded to an
`errorlog.md` so the records can be mined to improve skills and the command harness.

Implemented in two edits. First, added an **Error logging** bullet to the *Key rules
(always)* section of `.claude/CLAUDE.md`: on a genuine task-execution failure (failed
command, skill, or tool call), append a brief entry to repo-root `errorlog.md` with date,
machine (from `identity.json`), the failing command/skill, and the error — expected/handled
conditions excluded to keep the log signal-dense. Second, seeded the new `errorlog.md` at
repo root with a header and a fixed one-line entry format
(`YYYY-MM-DD | MACHINE | command/skill | error (brief)`, newest on top).

Surfaced the standing unread coord broadcast from GURU-KALI/claude-main (root `tmp/` now
gitignored + advisory promotion check wired into `/save` and `/scc`); no action required
beyond a `/sync` to pick up the harness change.

## Key Decisions

- **errorlog.md location = repo root, committed (not gitignored/per-machine).** A shared,
  synced log lets the whole fleet mine error patterns for harness/skill improvement, which
  is the stated purpose. Flagged to Mike as overridable.
- **Scope limited to genuine failures**, not expected/handled errors — keeps the log useful
  for spotting real harness/skill defects rather than noise.
- **Placed the rule in lean CORE `CLAUDE.md`** (Key rules, always-loaded) rather than
  EXTENDED, since it must fire on every session's errors to be effective.

## Configuration Changes

- Modified: `.claude/CLAUDE.md` — added **Error logging** bullet under *Key rules (always)*.
- Created: `errorlog.md` (repo root) — header + format spec, no entries yet.

## Infrastructure & Servers

None changed this session.

## Commands & Outputs

- `git status --porcelain | grep -E '\bsession-logs/.*\.md$'` — found one modified bot-activity
  log (`session-logs/bot/2026-06/2026-06-10-bot-activity.md`, 1-line append, not narrative work).

## Pending / Incomplete Tasks

- `/sync` still needed to pick up the GURU-KALI harness change (root `tmp/` gitignore +
  `tmp-promotion-check.sh` in `/save` and `/scc`).
- Active lock observed (not blocking this work): `wiki/clients/valleywide` held by
  GURU-5070/claude-main for `wiki-compile valleywide`, expires 2026-06-14T14:38:43.
