Investor deck rebuilt around Plan B (16 slides)

User, 19 Oct 2026: build the deck again but focus on Plan B, the main
investor wants to go with that.

- Proposes Plan B, ~217M THB at the midpoint (~6.56M USD), labelled
  ~215M; Plan A (~182M) only as the comparison. Every running footer,
  source line and speaker note now presents Plan B.
- New slide 9 "Why Plan B": ownership and control, not a higher
  modelled return (owned roof PV and battery instead of a PPA, full
  metrology from the first release, corridor and tours from day one,
  cassette and CD-R, bought crane, Thai utilities; ~34.5M THB together);
  Plan A has the better modelled return, owning the array earns no BOI
  tax benefit.
- Investment by block for Plan B with low-high ranges, the "what Plan B
  buys" table, no contingency (~30M at 15 %); operating picture, cash
  curve (payback ~4.2, IRR ~22 %, NPV ~4.7M USD) and BOI slide (equity
  at least ~54M THB at 3:1, owned PV and battery as collateral) for B;
  B-specific risks; the ask with the Plan B tranches only.
- Plan B renders replace the Plan A ones; PDF regenerated, 16 pages,
  1.5 MB.
- README and landing page entries say 16 slides and Plan B.
- Checks: every slide at 1920/1440/1280/390 px without overflow,
  navigation and presenter sync, PDF pages and text, no em dashes.

README.md

Test site: cnxvinyl.lol

https://cnxvinyl.lol/ is the internal test site for this repository: demo pages from docs/ (the plant operation page first) and any static site we want to show by link. It runs on the same web server as buildfor.life (Debian VPS s1, Caddy behind Cloudflare) and is not a plant service; plant systems follow the digital factory plan. Every page and file is sent with noindex and robots.txt disallows everything; nothing is behind a login unless basic_auth in the Caddyfile is switched on.

How it is built

public/ is copied verbatim to the web root: the landing page (index.html), robots.txt, and any static site as its own directory (public/<name>/index.html is served at /<name>/).
build.sh assembles site/dist: public/ plus every entry in its DEMOS list, which copies a page out of docs/ (for example docs/plant-operation.html to /demos/plant-operation/), so the docs stay the one source. It writes version.txt (the commit) and fails on any internal link that does not resolve.
To add a demo: one line in DEMOS, one entry on the landing page. To add a static site: drop its built output in public/<name>/ and link it.
Local preview: bash site/build.sh, then open site/dist/index.html.

How it is deployed

.gitea/workflows/deploy-site.yml runs on every push to master that touches site/, an HTML page under docs/, or the workflow itself, and on demand (Actions tab, "Run workflow"). It builds, rsyncs site/dist into the idle one of /var/www/cnxvinyl.lol and /var/www/cnxvinyl.lol-prev, swaps them by rename (the blog's pattern), checks version.txt on the server, purges the Cloudflare cache when the token is set, and finally checks the public URL (warning only).

The deploy owns the whole web root: anything put into /var/www/cnxvinyl.lol by hand disappears on the next deploy. Static sites go into public/ instead.

One-time setup

DNS in Cloudflare, both proxied (orange cloud): cnxvinyl.lol CNAME s1.buildfor.life and www CNAME cnxvinyl.lol (Cloudflare flattens the apex CNAME, so the site follows s1 if its address changes). SSL/TLS mode Full (strict): "Flexible" makes a redirect loop with Caddy.
Caddy on s1: append Caddyfile to /etc/caddy/Caddyfile (the comments in it list the checks), caddy validate, then systemctl reload caddy. Caddy gets the certificate the same way it does for the buildfor.life apex.
Web root: the deploy user must be able to create and rename directories in /var/www, as it already does for the blog. If not: sudo install -d -o <deploy user> /var/www/cnxvinyl.lol /var/www/cnxvinyl.lol-prev and make /var/www writable for that user (the swap renames entries in it).
Secrets in Gitea (repo: Settings > Actions > Secrets, or user level so every repo of the account gets them): VPS_HOST, VPS_USER, VPS_SSH_KEY, optionally VPS_PORT (default 22), VPS_KNOWN_HOSTS (output of ssh-keyscan -p <port> s1.buildfor.life, pins the host key), CLOUDFLARE_ZONE_ID and CLOUDFLARE_API_TOKEN (Zone > Cache Purge on cnxvinyl.lol). The names match the blog's workflow, so the blog's deploy key and values work unchanged: s1 only checks the key against the deploy user's authorized_keys, whichever repository sends it. Gitea secrets cannot be read back, so they are entered again here from the private key file; repo secrets set on B4L/buildfor_life_web do not reach this repository, B4L organisation secrets only reach it if it moves into B4L. The blog key is deploy@s1.b4l.co.th, fingerprint SHA256:o4w7HL+EsPI3MXbbcYWGn0EykN7qeLtYg0Tc9FI1a3s, and it is the only key in /home/deploy/.ssh/authorized_keys on s1 (sshd on port 2255, so VPS_PORT is 2255). The deploy log prints the fingerprint of the key in VPS_SSH_KEY; if it differs, the server answers "Permission denied (publickey)". If the private key is gone, make a new key instead: ssh-keygen -t ed25519 -N "" -C cnx_vinyl-deploy -f cnx_vinyl-deploy, public half into the deploy user's ~/.ssh/authorized_keys on s1, private half into VPS_SSH_KEY, then delete the local copy.
Runner: the job asks for ubuntu-latest, the label the blog's runner serves. This repository is under a user account, not the B4L organisation, so a runner registered only for B4L does not pick it up; if the run stays "Waiting", register the runner for this repository or instance-wide, or move the repository into B4L.
Run the workflow once from the Actions tab and open https://cnxvinyl.lol/.
