# Greenhouse Sensors: master record (current state)

Last updated 2026-01-05 (UTC). Last full audit: none yet. No secrets are stored here; section 1 says where they live. Related files: `working-agreement.md`, `runbook.md`, `sync-tracker.md`, `plans/backlog.md`.

# 1. Current state

## Headline facts
- _(five to ten lines a newcomer must know: what the system is, what is running, what is fragile, what is public, how it is backed up)_

## Components (inventory)
| Name | Role | Where / address | Version | Owner | Notes |
|---|---|---|---|---|---|
| _(component)_ | _(role)_ | _(host, URL, id)_ | _(version, verified YYYY-MM-DD)_ | _(who)_ | _(entity note file name)_ |

## Access (how work is done here)
- _(how to reach each system; the account or key NAME and where it is stored, never the secret)_

## Backups and recovery
- _(what is backed up, where, how often, how to restore, when a restore was last tested)_

## Security posture and decisions
- _(exposure, authentication, secrets storage, accepted risks with date and owner)_

## Secrets: where they live (values are never written here)
| Secret | Purpose | Lives in | Who can rotate | Rotation steps |
|---|---|---|---|---|

## Glossary and aliases
- _(one name per thing; list aliases used in code, dashboards and chat)_

# 2. Open items (priority order; master list of parked ideas is `plans/backlog.md`)
- _(item, owner, waiting on a date or event or decision, where details are)_

# 3. Quick reference and known quirks
- _(short list of traps; long form goes in `runbook.md`)_

# 4. Changelog (newest first)
- **2026-01-05 (notes repository created):** baseline created from the Myco Notes template. No system change.
