Last 1 Enterprises — Infrastructure Consolidation Plan¶

Status: Planning only (2026-08-20). Do not execute migrations from this document without Ryan review.
Branch: docs/last1-consolidation-plan (lastvet-gates). Do not merge until Ryan accepts sequencing.
Scope: Migrate Last 1 products off Railway + Supabase onto R940, one product (or tightly coupled bundle) at a time. SendGrid → RealSend is a separate track (pattern proven on MATR).
Drivers: cost, sovereignty story consistency, SOC 2 path for Onset, security posture.
Method: Read-only inventory from GitHub + Proxmox + existing gates docs. No Railway/Supabase/SendGrid/BWS mutations. No product code changes.

Executive summary¶

R940 has headroom (12 VMs, ~444 GiB RAM allocated of ~3 TiB; tank-fast ~13.8T free; tank-bulk ~55T free). Capacity is not the blocker. Coupling is.

Finding	Implication
Shared Supabase `tcthzakppndkykatoefx` (“Last 1 App + Radio Check”) is used by last1.app, RadioCheck, and last1-admin auth	Tier 6 must move as a bundle (or split the DB first). last1-admin compute can move earlier only if it keeps pointing at this project until the bundle cutover.
monthly-irs-sync is not a product	It is a Railway cron inside RealOutcomes (`railway.cron.toml`). Fold into RealOutcomes migration; do not schedule as a separate Tier 1 “product.”
onset-web is already off Railway	Cloudflare Pages. Railway/Supabase work for Onset is primarily clinic.theonset.app (+ shared Onset Supabase for mobile).
last1.id is identity critical path	RadioCheck edge `last1-id-callback`, LastVet/Onset OAuth env surface, admin gateway. Treat as high-risk and migrate before or carefully coordinated with dependents.
Per-tenant Postgres remains the R940 rule	Do not dump all products into one shared Postgres. Keep clinical/identity boundaries. The existing last1.app↔RadioCheck share is a legacy exception to resolve deliberately in Tier 6.
Live Railway memory/replicas and Supabase sizes	Not readable from this host (no Railway CLI session; Supabase MCP unauthenticated; BWS not queried for DB passwords). Repo-committed config + project refs are below; dashboards needed for exact $ and row counts.
Recommended BW pattern	Per-product prefixes (`LAST1ID_R940_`, `ONSET_R940_`, …), not a universal `LAST1_R940_*` namespace. Aligns with existing `LASTVET_` / `ANGEL_` / `SOVEREIGN_` / `MERIDIAN_`. Extension drafted in naming convention doc.

Recommended sequence adjustments vs Ryan’s draft tiers: (1) demote standalone monthly-irs-sync; (2) keep n8n as Tier 1 warm-up; (3) allow last1-admin compute in Tier 2 but defer its Supabase until Tier 6; (4) treat last1.app + RadioCheck (+ admin auth DB) as one Tier 6 cutover; (5) keep Onset clinical as Tier 5 SOC 2 driver; (6) run SendGrid→RealSend as parallel batch, not interleaved with DB cutovers.

STOP: After this report, wait for Ryan to pick a start product and approve playbook + BW naming before any provisioning.

Investigation limits (honesty box)¶

Source	Status
GitHub repos (Last-1-Enterprises)	Read via `gh` API
Proxmox `pve-r940` (`qm list`, zpool, node memory)	Read via SSH
Railway dashboard (memory, replicas, live env, $)	Unavailable (`railway` CLI not installed/authed)
Supabase dashboard (disk size, extensions UI, live RLS count, MAU)	Unavailable (MCP `needsAuth`; no project passwords used)
BWS secret values	Not touched (constraint). Key names in last1-admin project were previously known from ops context; not re-listed here
User counts / PHI volume	Not determinable without DB login

Where numbers are approximate, they are labeled.

Users	Internal automation
Data posture	Workflow credentials may include secrets; inventory workflows before move
SendGrid	None in repo (workflows may call SendGrid; unknown)

8. monthly-irs-sync¶

Not a standalone product. See RealOutcomes cron above. Migration effort folds into RealOutcomes (add a systemd timer or cron on the RealOutcomes R940 VM).

Sub-task B — R940 capacity¶

Current inventory (2026-08-20, `qm list` on pve-r940)¶

VMID	Name	RAM (MiB)	Boot disk (GB)
100	agent-01	98304	200
101	inference-01	65536	150
102	meridian-eval	32768	100
103	meridian-rag	65536	100
104	sovereign-app	32768	100
105	sovereign-mem	32768	100
106	angel-local	49152	100
107	lastvet-api	16384	100
108	lastvet-db	32768	100
109	lastvet-imaging	8192	100
110	lastvet-edge	4096	50
111	observability	16384	50

VM count: 12 running
RAM allocated: ~444 GiB of ~3.0 TiB host (~14.5%). ~2.8 TiB available on host metrics.
Storage: tank-fast 13.9T ~13.8T free; tank-bulk 55.9T ~55.3T free (ZFS avail metrics).

Product	Recommendation
n8n	Small shared ops VM or dedicated 2 vCPU / 4–8 GB
last1-admin	Dedicated small app VM (or share ops VM initially)
RealOutcomes	App VM + own Postgres (or Postgres on same VM if tiny; prefer separate DB disk)
last1.id	Dedicated app + dedicated Postgres (identity blast radius)
Onset clinic	Dedicated app + dedicated Postgres (clinical boundary)
last1.app + RadioCheck	One shared Postgres until intentional split; 1–2 app tiers (API/edge replacement)
Object storage	Prefer Supabase Storage → MinIO only where needed; do not put clinical objects on `lastvet-imaging` without a new trust-boundary design

Postgres consolidation decision¶

Decision recommendation (aligns with R940 architecture):

Default: one Postgres per trust boundary (LastVet already separate; Onset separate; last1.id separate; RealOutcomes separate).
Exception: keep last1.app + RadioCheck on one Postgres through Tier 6 cutover; schedule a later split only if product/legal boundaries require it.
Reject: single “all Last1” Postgres on one VM. Violates documented per-tenant sovereignty and complicates SOC 2 / incident scope.

MinIO¶

LastVet already owns lastvet-imaging. New product object stores should be new ZFS datasets / MinIO instances (or temporary continue Supabase Storage until product cutover). No evidence these Railway products currently use R940 MinIO.

Sub-task C — Sequencing recommendation¶

Ryan’s draft (kept as spine)¶

Tier	Intent
0	Prerequisites (playbook, BW naming, capacity)
1	Low-risk warm-ups
2	Internal tools
3	Bounded real users
4	Critical identity (last1.id)
5	Clinical / PHI (Onset bundle)
6	Platform apps (last1.app + RadioCheck)

Adjustments¶

Change	Why
Tier 0 now	This document + BW naming extension + Muster items. Capacity already green. Still need: Railway/Supabase dashboard export for $ and sizes; RealSend capacity confirmation.
Tier 1 = n8n only	monthly-irs-sync is not separable; moving it alone teaches little and risks splitting RealOutcomes.
Tier 2 = last1-admin compute	Move Railway Node to R940; keep Supabase auth on `tcthzakppndkykatoefx` until Tier 6. Reduces Railway spend without DB surgery.
Tier 3 = RealOutcomes including IRS cron	Bounded product; own Supabase; good second full-stack rehearsal after n8n.
Tier 4 = last1.id	Still high risk. Prefer before Tier 6 (RadioCheck depends on it). Soft-block: document OAuth redirect URI + webhook secret rotation checklist.
Tier 5 = Onset clinic + Onset Supabase (+ mobile env cuts)	SOC 2 driver. onset-web stays on Cloudflare.
Tier 6 = last1.app + RadioCheck (+ last1-admin auth DB)	Mandatory bundle. Highest coordination cost.
Parallel: SendGrid → RealSend	Do not interleave domain warmup with DB cutovers. Batch domains; cut after warmup.

Suggested calendar shape (planning only)¶

Approve this plan + BW naming.
n8n (1–3 days).
last1-admin compute (2–4 days).
RealOutcomes full (1–2 weeks).
last1.id (2–3 weeks, freeze window).
Onset clinic (multi-week; counsel/SOC 2 aware).
last1.app + RadioCheck bundle (multi-week).

Effort estimates assume Cursor + Ryan review; LastVet AWS retirement lessons (~days per bounded workload) scale up for identity/clinical.

Sub-task D — Bitwarden naming decision¶

Recommendation: per-product prefix, not universal LAST1_R940_*.

Option	Pros	Cons
Universal `LAST1_R940_*`	Fewer prefixes	Collides with `LAST1_PLATFORM_*`; weak blast-radius grep; fights existing LastVet/Angel pattern
Per-product `LAST1ID_R940_`, `ONSET_R940_`, `LAST1APP_R940_`, `RADIOCHECK_R940_`, `REALOUTCOMES_R940_`, `LAST1ADMIN_R940_`, `N8N_R940_*`	Matches `LASTVET_` / `ANGEL_`; clear ownership; project-per-product in BWS	Slightly more prefixes

Rule: LAST1 / LAST1_PLATFORM remains cross-product only. Product runtime secrets use product codes above. Extension recorded in BITWARDEN_NAMING_CONVENTION.md.

Sub-task E — Generic migration playbook¶

Reuse per product. Pattern distilled from LastVet AWS→R940 retirement and R940 platform rules.

1. Pre-migration audit¶

[ ] Confirm main SHA and open PRs
[ ] Export Railway service settings (build/start, memory, replicas, volumes, cron)
[ ] Export Supabase: Postgres version, disk, extensions, RLS policy count, Auth providers, Storage buckets, Edge function list
[ ] Data volume + user/org counts
[ ] Dependency map (OAuth, webhooks, admin gateways)
[ ] User impact window + rollback owner

2. R940 target provisioning¶

[ ] Allocate VMID, hostname, LAN IP, MagicDNS (*.tailc3bbdc.ts.net)
[ ] Size vCPU/RAM/disk from audit; place data on tank-fast (or bulk if object-heavy)
[ ] Join Tailscale with tagged auth key pattern (tag:r940-vm) when ready
[ ] UFW: Tailscale/LAN only for admin ports; public only via approved edge

3. Database / object store / secrets¶

[ ] Provision Postgres (per trust boundary)
[ ] Roles: migrate-style *_master / *_app split where applicable
[ ] Restore logical dump from Supabase; verify extensions (pgcrypto, etc.)
[ ] Recreate Storage → MinIO only if required; else temporary dual-run
[ ] Create BWS keys under product prefix; map to runtime names in systemd drop-in

4. Code / config changes¶

[ ] Prefer env-only cut (connection strings, URLs). Avoid app renames of BWS keys.
[ ] Replace Supabase Auth carefully (GoTrue vs first-party auth is a product decision; default = keep Supabase Auth temporarily via self-host or cut Auth in a dedicated phase). Flag: Auth migration may dwarf “move Postgres.”
[ ] Update redirect URIs, webhooks, Stripe endpoints

5. Deployment runbook¶

[ ] systemd units (app + optional side workers)
[ ] Health checks (/api/health or product equivalent)
[ ] Log shipping to observability (Promtail) when ready
[ ] Backup: vzdump + logical dump schedule

6. Cutover¶

[ ] DNS / Cloudflare / Railway custom domain drain
[ ] Freeze writes if dual-write not available
[ ] Final dump + restore or continuous replication catch-up
[ ] Flip env; verify auth login, critical writes, admin proxy
[ ] Watch error budgets 24–72h

7. Rollback¶

[ ] Keep Railway service stopped but not deleted for N days
[ ] Keep Supabase project until rollback window closes
[ ] DNS TTL lowered before cutover
[ ] Document “flip back” owner and checklist

8. Cleanup¶

[ ] Delete Railway service/project after window
[ ] Delete Supabase project after window + legal retention check
[ ] Confirm invoice lines gone
[ ] Remove retired _RAILWAY_ / old secrets after rotation

9. Documentation¶

[ ] Update R940_PLATFORM_ARCHITECTURE.md tenant map
[ ] BWS manifest / naming
[ ] Product runbook under docs/
[ ] Muster item → done with note

Auth special note: Several products are “Supabase = Auth + DB + Edge.” Moving DB only while leaving Auth on Supabase is a valid interim (hybrid). Moving Auth requires either self-hosted GoTrue/Supabase stack or product rewrites. Decide per product in Tier 0 kickoff.

Sub-task F — Cost analysis¶

Live invoices not read. Use as planning priors; replace with dashboard exports before committing savings claims.

Line	Estimate basis	Monthly (order of magnitude)
Supabase projects (≥4–5 Pro-class)	Public Pro list price ~$25/project	~$100–200+ if all Pro; Team/spend caps higher
Railway services (last1.id, clinic, last1.app, admin, RealOutcomes, n8n, IRS cron)	Usage + plan	~$50–300+ highly usage-dependent
SendGrid	Shared account / multiple senders	~$15–100+ tier-dependent
R940 marginal	Hardware already owned; power/network sunk	~$0 compute marginal; ops time is the cost
Annual savings (compute hosting)	If Railway+Supabase ≈ $200–500/mo	~$2.4k–6k/yr before labor; verify with invoices

Not included: engineer time, RealSend fees, dual-run periods, SOC 2 audit spend (Onset driver is compliance, not pure hosting savings).

Sub-task G — SendGrid → RealSend (separate track)¶

Known sender domains / addresses¶

From product repos (active senders) plus the broader SendGrid authenticated-domain list Ryan already inventoried:

Domain / address	Likely class	In consolidation scope?
`notifications@theonset.app` / `updates@theonset.app` / `theonset.app`	Transactional + marketing	Yes (Onset)
`hello@realoutcomes.app` / `realoutcomes.app`	Transactional	Yes
`noreply@last1.app` / `last1.app`	Transactional	Yes
`integrations@last1.id`	Transactional optional	Yes
`radiocheck.app`	Transactional (Pro/Enterprise)	Yes (often via last1.app sender)
`last.vet`	Transactional	LastVet track (already R940 path)
`angel.report`	Transactional	Angel (Cloudflare; separate)
`last1.enterprises`, `last1.capital`, `last1.studio`, `veteransco.org`, `www.last1.org`	Mixed / claimed	Confirm active vs territory before warmup

Plan¶

Inventory one SendGrid account: authenticated domains, PTR/SPF/DKIM, templates, webhook events.
Confirm RealSend capacity + MATR lessons (reference-matr-sendgrid-realsend-migration-patte).
Warmup calendar per domain (do not cut cold).
Implement provider abstraction or env swap per product (EMAIL_PROVIDER=realsend).
Coordinated cutover weekend; keep SendGrid read-only 14 days.
Do not couple to Postgres cutover night.

Sub-task H — Muster items¶

Filed as status: later (see muster tracker.yaml on main after PR/commit). IDs:

Open questions for Ryan¶

Accept per-product BWS prefixes as written?
Accept Tier 1 = n8n only and IRS folded into RealOutcomes?
For Supabase Auth: hybrid (DB on R940, Auth stays Supabase) allowed as interim?
Provide Railway + Supabase billing exports to harden Sub-task F.
