Chronicles settled battles, reverts, and dead ends. Use when a fix echoes a past failure. Do not use for live triage; use night-market-debugging-playbook.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Night Market Failure Archaeology

This is a reference document, not a runbook. It records every major
investigation, dead end, rejected fix, and revert in this repo as
symptom, root cause, evidence, status, and lesson, so nobody re-fights
a settled battle. For triage of a failure happening right now, use
`night-market-debugging-playbook`. Come here when a proposed change
smells like something the repo already tried and rejected.

Jargon used below:

- "py39 hooks": hook scripts run under the host system Python (3.9
  floor), while the rest of the repo requires Python 3.12. Enforced by
  `.github/workflows/python39-compat.yml`.
- "unbloat": the conserve plugin's dead-code deletion campaign.
- "Stop hook": a Claude Code hook that runs when a session turn ends.
- "settled": the fight is over. Re-opening it requires new evidence
  and a note in the collective memory, not a hunch.

## How to use this chronicle

1. Before implementing, scan the battle titles and the recurring-class
   table for anything resembling your plan.
2. If a battle matches, read its lesson. Follow it, or write down why
   this time is different before overriding it.

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/night-market-failure-archaeology@sha256:c362bc5eda92a347

The line at the top of this page pins the label git:20260703.19ab4d6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
