Summary

Stability and usability for the Odoo test instances (never production), items 1-8 of the design review.

odoo-<name>.service  ExecStartPre (each idempotent, logs "pre-start: ...")
  1 runtime config + master password
  2 first start: --init=base,<modules> [--with-demo] [--load-language]
      odoo neutralize -> blocking "invalid" mail server replaced by "Mailpit", mail queue on
      markers .package .modules .golden-pending
  3 sync: package/addons changed -> -u all ; modules added -> install (+ neutralize)
  4 +root: .golden-pending -> CREATE DATABASE odoo-<name>@golden TEMPLATE odoo-<name>, tar files
  5 admin password ; web.base.url (public)
  Restart=on-failure (10 s, 4 per 15 min)  MemoryMax=<memoryMax>

#	Change
1	Restart=on-failure; scripts reset-failed before deliberate starts (the start limit counts every start)
2	memoryMax (4G), limits.{memorySoft,memoryHard,timeCpu,timeReal}, max_cron_threads=1
3	reset copy: odoo-reset restores in seconds; --clean; stale when package/addons/demo/apps/language change; --list shows ready/stale/none
4	odoo-snapshot save|restore|list|rm NAME TAG (template DB + files)
5	modules (apps at creation; added later -> installed), language
6	Mailpit (https://mail.<baseDomain>, LAN too), neutralize, default sender <name>@<baseDomain>
7	package or addons change -> -u all on next start, data kept
8	breaking: lan.addresses removed; LAN vhosts listen on every address; http://<IP>/hosts.txt (nginx fills in $server_addr) and /ca.crt bootstrap a client; odoo-hosts reads the live address; allow-list for return locations via a geo map

Evidence

Bugs the tests caught on the way (fixed): nginx return ignoring allow/deny (stranger got hosts.txt), the start limit locking an instance out after quick resets, neutralize's invalid mail server blocking all mail, no sender on system mail.

vm-test --check                              8 tests evaluate and fit the caps
vm-test odoo --remote --quiet                exit 0   17 subtests (+ crash restart, memory caps)
vm-test odoo-reset --remote --quiet          exit 0    9 subtests (reset copy in seconds, --clean, stale, snapshots, purge)
vm-test odoo-lifecycle --remote --quiet      exit 0    5 subtests (apps, neutralize, Mailpit, -u all + install, quiet restart)
vm-test odoo-lan --remote --quiet            exit 0    9 subtests (IP bootstrap, allow-list incl. hosts.txt, DHCP change)
vm-test odoo-public --remote --quiet         exit 0    5 subtests
vm-test odoo-firefox --remote --quiet        exit 0    3 subtests
each result == nix eval .#legacyPackages.x86_64-linux.vmTests.<t>.outPath of this commit (identical before and after rebasing onto #40)
fmt; check                                   exit 0

Merge Danger

Door: two-way

Breaking: hostSpec.services.odoo.lan.addresses is gone (no shim); home's beelink config drops it in its PR. Existing instances get the new markers on their next start without -u all; their reset copy is made on the first odoo-reset (from scratch once).

Blast Radius: beelink

Replaces #41 (its head became an unsigned server-side rebase). Merge order: pkgs#30, skills#17, modules#40 (all merged), this -> home#44 bumps modules and drops lan.addresses.
