Salvage the unit-budget implementation from #104745, replacing its test
matrix with two invariant tests and covering the sibling graceful start.
Keep unprivileged property reads, finite fallbacks, real manager errors,
and post-restart health verification.
Native disposable user unit: old client timed out after 15.03 seconds;
new client completed the same 16-second stop transaction in 16.13 seconds.
The unit stayed active with a new PID; missing-unit errors stayed errors.

Root AGENTS.md 100,797 → 29,295 chars: what applies everywhere (invariants, rubric, footprint ladder, layout + shape rules, commit/PR, testing) plus a routing table. Area rules move to agent/, hermes_cli/, gateway/, tools/, plugins/, tui_gateway/, web/, skills/, cron/, apps/desktop/src/ AGENTS.md (3–9k each; ceiling is now 32k after d61cff60e3, target ~8k). Long-form process-identity and skin key tables go to website/docs/developer-guide/cli-internals.md. Zero rule loss; map in /tmp/rf/agents_md_zero_loss.md. Stale Bot Mode test paths corrected to apps/desktop/src/plugins/hermes-bots/*.test.ts.
