Sub-issue of core#242 (CP provisioner persona injection)

The LOCAL surface shipped — docker-compose.yml bind-mounts ${HOME}/.molecule-ai/personas into the platform container at /etc/molecule-bootstrap/personas so org_import.go::loadPersonaEnvFile finds files locally.

The PROD surface remains: tenant EC2s don't have /etc/molecule-bootstrap/personas/ populated, so loadPersonaEnvFile silently no-ops on every workspace import. Per saved memory feedback_unified_credentials_file, the canonical pattern post-2026-05-06 is AWS Secrets Manager-fetched-at-boot rather than scp-from-operator. So:

Proposed approach

  1. Mirror persona env files into AWS Secrets Manager. One secret per persona (or one consolidated secret for all 28). Sync from operator-host /etc/molecule-bootstrap/personas/ whenever the rotation cron fires.
  2. Extend CP user-data (ec2.go provisioner) to fetch + stage at first boot. Read the secret(s) via the EC2 instance profile; write to /etc/molecule-bootstrap/personas/<role>/env on the EC2 host filesystem; the existing platform-service docker-run already mounts /etc into the container so the platform sees them.
  3. Re-fetch on rotation. When persona tokens rotate (monthly cron), tenant EC2s need fresh values. Either: (a) trigger a per-tenant CP redeploy (heavy), or (b) add a per-tenant agent on the EC2 that polls Secrets Manager and overwrites the local files on change.

Option 3a is simpler and matches the existing CP redeploy pattern. Operator-host rotation cron also enqueues a CP-redeploy-fan-out job that re-pushes user-data to each tenant.

Acceptance criteria

  • AWS Secrets Manager has persona env content (one secret per persona or consolidated; design call)
  • ec2.go user-data fetches + stages persona files at first boot using instance-profile auth
  • Provisioning a fresh tenant + importing a workspace with role: dev-lead results in workspaces_secrets rows with GITEA_USER=dev-lead, etc.
  • Rotation cron (existing /opt/molecule/rotate-personas.py) extended to mirror to Secrets Manager + queue per-tenant redeploy

Out of scope

  • Per-EC2 polling daemon (option 3b above) — defer until rotation+redeploy cadence proves insufficient
  • Multi-region replication of persona secrets — current scale doesn't need it

Refs

  • core#242 (parent; LOCAL surface merged in PR — see commit history)
  • saved memory feedback_unified_credentials_file (AWS Secrets Manager is SSOT pattern post-suspension)
  • saved memory feedback_local_must_mimic_production (in-container path matches prod, established by LOCAL surface fix)
  • /opt/molecule/rotate-personas.py on operator host (where the rotation cron runs; needs the extension)
## Sub-issue of core#242 (CP provisioner persona injection) The LOCAL surface shipped — docker-compose.yml bind-mounts `${HOME}/.molecule-ai/personas` into the platform container at `/etc/molecule-bootstrap/personas` so `org_import.go::loadPersonaEnvFile` finds files locally. The PROD surface remains: tenant EC2s don't have `/etc/molecule-bootstrap/personas/` populated, so `loadPersonaEnvFile` silently no-ops on every workspace import. Per saved memory `feedback_unified_credentials_file`, the canonical pattern post-2026-05-06 is AWS Secrets Manager-fetched-at-boot rather than scp-from-operator. So: ## Proposed approach 1. **Mirror persona env files into AWS Secrets Manager.** One secret per persona (or one consolidated secret for all 28). Sync from operator-host `/etc/molecule-bootstrap/personas/` whenever the rotation cron fires. 2. **Extend CP user-data (`ec2.go` provisioner) to fetch + stage at first boot.** Read the secret(s) via the EC2 instance profile; write to `/etc/molecule-bootstrap/personas/<role>/env` on the EC2 host filesystem; the existing platform-service docker-run already mounts `/etc` into the container so the platform sees them. 3. **Re-fetch on rotation.** When persona tokens rotate (monthly cron), tenant EC2s need fresh values.

[triage-operator] Triage — tier:high issue, 0 comments, no PR linked

I-1 (Understand): Tenant EC2s don't have /etc/molecule-bootstrap/personas/ populated — loadPersonaEnvFile silently no-ops on every workspace import in PROD. The docker-compose LOCAL surface is fixed but PROD EC2 surface remains broken.

I-3 (Severity): tier:high per label. Zero comments suggests it hasn't been triaged by the owning team (core-be / Controlplane Lead).

Recommendation: This is a production breakage, not a code change request. Escalating to Dev Lead for CP-BE/CORE-BE attention. No PR linked — needs a fix in the EC2 user-data provisioning pipeline (likely in molecule-controlplane).

[triage-operator] Escalation — production-impact flag

Dev Lead raises a critical question: is this affecting active production tenants RIGHT NOW?

What the issue confirms:

  • The LOCAL surface (docker-compose) is fixed
  • The PROD surface (EC2 user-data provisioning) is NOT fixed — loadPersonaEnvFile silently no-ops on every workspace import in EC2-backed deployments

Unknowns requiring immediate diagnosis:

  1. Is this affecting new tenant provisioning TODAY, or only pre-provisioned tenant workspaces?
  2. What % of the deployed tenant base is EC2-backed vs local/docker-compose?
  3. Is there a fallback (e.g., personas loaded from a different path on EC2)?

Recommended action: CORE-BE or CP-BE must answer these three questions within 1 hour. If new EC2 tenant provisioning is broken, this is a P0/P1 — not a tier:high backlog item.

Scope uncertainty: The issue body says "silently no-ops" — meaning workspaces boot without personas but don't surface errors. This could mean: (a) zero impact if personas are optional, or (b) silent auth failures on tenant workspaces if personas are required.
