Caching (reduce MCMS API load with multiple operators):
- web/cache.js: in-memory TTL cache with single-flight, keyed by MCMS host.
Concurrent identical bulk reads collapse into ONE upstream fetch; everyone
on the same MCMS shares the snapshot.
- Wired into the bulk reads only (ONU/OLT config+state lists, controllers,
firmware). Per-ONU read-modify-write and the FEC pre-flight stay live.
- Writes (delete / per-ONU + bulk upgrade / flood change / firmware upload)
invalidate the affected datasets for that host, so changes show on the
next load instead of waiting out the TTL.
- PFW_CACHE_TTL_SECONDS (default 60, 0 disables). Authenticated
_cacheStats / _cacheClear endpoints for ops.
Deploy (Debian 13 LXC, clone-to-run) in web/deploy/:
- pon-fleet-web.service (runs as unprivileged ponfw, hardened, repo
read-only, no disk writes), pon-fleet-web.env.example, update.sh
(git pull + npm install --omit=dev + restart; uses install not ci since
package-lock.json is gitignored).
- README: full LXC setup, Nginx Proxy Manager proxy-host + access-list
notes. Streams already send X-Accel-Buffering: no so NPM/nginx don't
buffer the NDJSON progress.
Verified: node --check; cache unit-tested (single-flight, TTL hit/expiry,
fresh, invalidate, key isolation, disable — 9/9); server boots and reports
the cache TTL; _cacheStats gated to logged-in sessions.

New web/ subfolder: a Node http server that serves the SAME tooling as the
Electron app to any browser, with per-session MCMS credentials so several
operators can use it at once behind a TLS reverse proxy. Mobile-responsive.
Not a fork — it reuses the core and the UI:
- serves renderer/app.js + app.css verbatim and rewrites index.html on the
fly (mobile viewport + browser window.api shim + responsive overlay)
- web/public/api-web.js: a drop-in window.api over fetch + NDJSON streaming;
Electron file dialogs -> <input type=file>, CSV-to-Downloads -> Blob
- web/server.js: per-session McmsClient (cookie pfw_sid), idle expiry,
routes mirroring the IPC handlers, NDJSON for the 6 streaming ops
- pure Node http, no new deps (borrows ../node_modules tough-cookie)
Shared improvements (benefit both apps):
- src/dashboard.js: extracted, pure dashboard aggregation (main.js now uses
it); adds abnormal-Tx detection alongside abnormal-Rx
- renderer: dashboard health stats are now clickable — abnormal Rx / Tx /
lasers-off pop a list of the offending devices (like the iOS app), via a
new showListModal
Docs: web/README.md (run + reverse-proxy + security), CLAUDE.md §16.
Verified: node --check all; started the server and confirmed transformed
index, shared-asset serving, 401 auth gate, login (per-session client), and
NDJSON wiring; rendered login + dashboard drilldown + mobile over HTTP.
