 2026-08-29T06:03:06-05:00 | PMO | 3 turns verified+archived (quota fc518c4, deploy b7799ea, pdf 10e930e); Redmine 490/491/494/499 -> Done 100%; briefing RUNNING; dispatcher gated
 2026-08-29T06:19:13-05:00 | PMO | 497 amended: per-account BW scale (100+ refs), one bootstrap seed per account, batch warm + memory cache
 2026-08-29T06:19:29-05:00 | PMO | 497 corrected: BW machine accounts map to CLOUDRON accounts (per-vertical API identities), not raw Linux accounts
+2026-08-29T06:20:17-05:00 | PMO | identity model ticket filed (linux runtime + cloudron acting, N per account); 497 corrected

+- **1:1 Linux account to Bitwarden account.** Each of the 9 Linux accounts has exactly ONE Bitwarden account (machine account). That single vault contains ALL credentials for the vertical: its Cloudron account details AND all third-party accounts (Google, Signal, Discord, IMAP, Linkwarden, ...) — potentially a dozen or more secrets per account, 100+ fleet-wide.
+- Bootstrap = exactly one 0600 seed env-file per Linux account provisioned by the deploy installer (install-account.sh); everything else resolves from that account's BW vault at runtime. One secret per Linux account ever touches disk, and only that one.
+- Ref namespace is instance-local: mpk- refs resolve against THAT account's BW projects/secrets; same ref names across accounts are a feature.
+- Batch + cache: startup warm = list projects + secrets once (bitwarden-go list support); memory-only TTL cache; refresh on miss. No per-ref cold calls in the dispatch path.
+- Fleet inventory: BW project/secret listing doubles as credential inventory for audits (never materializing values).
+- Acting identities (#517) remain Cloudron accounts / 3rd-party accounts; they are ENTRIES in the per-Linux-account vault, selected by ref.

+Acceptance additions: fixture test with 2 fake Linux accounts x 15 secrets each (mixed cloudron + 3rd-party); warm-cache latency documented; bootstrap-seed flow in deploy runbook.
