+# FleetOps — Platform Audit Report (2026-07-02)
+
+Part of the 2026-07-02 cross-repo audit (tracksolid + fleettickets + fleetops; see
+the tracksolid repo's `docs/reports/260702_platform_audit_report.md` for the
+DB/host-wide findings). Scope here: the SPA (`src/index.html` + `src/env.js`),
+the Caddy/Docker serving layer, and the two deployed containers on twala.
+Companion docs: `260702_fix_plan.md`, `260702_work_done.md`.
+
+---
+
+## High
+
+### FO-SEC-01 — Stored XSS: API strings rendered into `innerHTML` unescaped
+The tickets explorer and map popups escape correctly (`escapeHtml`), but the
+**logistics tables (`renderVehicles`, `renderDrivers`), the fuel banner notes, and
+all three Fuel Log tables (`renderFuelVehicles`, `renderFuelDepartments`,
+`renderFuelRecent`)** interpolate API strings straight into `innerHTML`. The Fuel
+Log fields (`driver`, `department`, `fuel_type`, `plate`) originate from **WhatsApp
+messages** — genuinely user-generated content — and vehicle/driver names come from
+the Tracksolid registry, editable by any fleet-console user. A crafted name like
+`<img src=x onerror=…>` executes in every dispatcher's browser. Error banners also
+render `e.message` unescaped (server-influenced text).
+
+### FO-SEC-02 — CDN scripts loaded without Subresource Integrity
+Chart.js (jsdelivr) and MapLibre (unpkg) load with no `integrity`/`crossorigin`
+attributes — a compromised or MITM'd CDN response executes arbitrary script with
+access to the fleet APIs.
+
+### FO-SEC-03 — No security headers from Caddy
+No `Content-Security-Policy`, `X-Content-Type-Options`, `Referrer-Policy`, or
+frame-ancestors protection. Combined with FO-SEC-01 this leaves injected markup
+free to load external script and exfiltrate anywhere.
+
+## Medium
+
+### FO-BUG-01 — `loadLive()` parses the response without checking `r.ok`
+A 4xx/5xx from `/webhook/live-positions` throws inside `r.json()` on non-JSON
+bodies with an unhelpful error; harmless but noisy.
+
+### FO-BUG-02 — Live-position poll never pauses
+The 15-second `/webhook/live-positions` poll starts when the Tickets map is first
+opened and then runs forever — including when the user is on the Logistics/Fuel
+tabs and when the browser tab is hidden overnight. A dashboard left open ≈ 5,760
+wasted API calls/day per viewer.
+
+### FO-OPS-01 — Fallback API base pointed at *staging*
+`index.html` fell back to `https://fleetapi.fivetitude.com` when `env.js` isn't
+templated. CLAUDE.md documents the intended fallback as the **prod** API. A prod
+pod missing `API_BASE` would silently lean on the staging bridge (and fail CORS
+confusingly).
+
+## Notes / by design
+
+- **FO-OPS-02** — the prod container (`API_BASE=fleetapi.rahamafresh.com`) runs
+  commit `21bca24`, ~19 commits behind HEAD — this is the documented frozen-prod
+  staging-umbrella pattern, not drift. But note: **promotion must pair the SPA
+  deploy with the prod `dashboard_api` bridge redeploy** — prod's bridge currently
+  lacks all `/webhook/{inc,crq}-*` and `/analytics/fuel-fills` routes the newer
+  SPA calls (see the tracksolid audit, OPS-01).
+- **FO-OPS-03** — untracked scratch files at the repo root
+  (`marker-preview.html`, `tracksolid_db_connection.md`, `webook_instructions.txt`).
+  `tracksolid_db_connection.md` documents the public `twala:5433` superuser
+  connection pattern that the tracksolid audit is eliminating — update or remove
+  once the SSH-tunnel workflow lands.
+- The serving layer is otherwise good: Caddyfile validated at build time,
+  healthcheck endpoint, runtime `API_BASE` injection via `templates`, `no-store`
+  on the shell and env.js.

+# FleetOps — Fix Plan (2026-07-02)
+
+Companion to `260702_audit_report.md` and `260702_work_done.md`.
+
+## Phase A — repo changes (implemented in this session)
+
+| Step | Finding | Change |
+|---|---|---|
+| A1 | FO-SEC-01 | Hoist `escapeHtml` into the HELPERS section, add an `esc()` convenience (escapes or em-dashes), and route every API string in the logistics + fuel renderers and the three error banners through it. The tickets code already escaped — now the whole file is consistent. |
+| A2 | FO-SEC-02 | Add `integrity="sha384-…" crossorigin="anonymous"` to the three CDN assets (hashes computed from the exact pinned files; recompute command documented inline). |
+| A3 | FO-SEC-03 | Caddyfile: `X-Content-Type-Options: nosniff`, `Referrer-Policy`, `frame-ancestors 'none'`, and a CSP restricting script/style/img/font/connect origins to self + the two pinned CDNs + CARTO + the two fleet APIs. `script-src` keeps `'unsafe-inline'` (the app is one inline script block); the CSP's value here is limiting external script origins and exfil targets. |
+| A4 | FO-BUG-01/02 | `loadLive()` checks `r.ok`, and skips while `document.hidden` or when the Tickets tab isn't active; switching back to Tickets (or the page becoming visible) triggers an immediate refresh so markers don't wait out the 15 s interval. |
+| A5 | FO-OPS-01 | Fallback API base flipped to the prod bridge (`fleetapi.rahamafresh.com`), matching the documented design. |
+
+## Phase B — operational (needs operator decision)
+
+| # | Item |
+|---|---|
+| B1 | Promotion pairing: when this branch is promoted to prod (Coolify deploy of fleetops.rahamafresh.com), redeploy the prod `dashboard_api` bridge first — it currently lacks the `/webhook/{inc,crq}-*` + `/analytics/fuel-fills` routes the SPA calls. |
+| B2 | Clean up untracked root scratch files; rewrite `tracksolid_db_connection.md` for the SSH-tunnel workflow once the DB port closes. |
+| B3 | Longer-term: consider vendoring Chart.js/MapLibre into `src/` (removes the CDN trust surface entirely and lets the CSP drop jsdelivr/unpkg). |
+
+## Verification
+- Extracted inline script passes `node --check`.
+- Caddyfile passes `caddy validate` (run inside the deployed fleetops image).
+- Manual: staging deploy → open all four tabs, confirm charts/map/popups render,
+  check DevTools console for CSP violations before promoting.

+# FleetOps — Work Done (2026-07-02)
+
+Execution log for `260702_fix_plan.md` Phase A. **Local changes only — nothing
+committed, pushed, or deployed.**
+
+## Changes
+
+| Finding | Files | What changed |
+|---|---|---|
+| FO-SEC-01 | `src/index.html` | `escapeHtml` moved to HELPERS with a new `esc()` shorthand; all previously-unescaped API strings now escape: `renderVehicles` (vehicle_number, cost_centre, assigned_city), `renderDrivers` (driver_name, assigned_city), `renderFuel` banner notes, `renderFuelVehicles`, `renderFuelDepartments`, `renderFuelRecent` (plate, department, driver, fuel_type), and the three catch-block error banners (`e.message`). WhatsApp-sourced Fuel Log strings can no longer inject markup. |
+| FO-SEC-02 | `src/index.html` | SRI `integrity` + `crossorigin="anonymous"` on Chart.js 4.4.1, maplibre-gl 4.7.1 JS and CSS (sha384 computed from the exact CDN payloads; recompute one-liner documented inline for future bumps). |
+| FO-SEC-03 | `Caddyfile` | Security header block: `nosniff`, `Referrer-Policy: strict-origin-when-cross-origin`, CSP (self + pinned CDNs + CARTO basemap + the two fleet APIs; `worker-src blob:` for MapLibre; `frame-ancestors 'none'`), `-Server`. `script-src` retains `'unsafe-inline'` because the app is a single inline script block. |
+| FO-BUG-01 | `src/index.html` | `loadLive()` now throws on non-OK responses instead of parsing error bodies. |
+| FO-BUG-02 | `src/index.html` | The 15 s live-position poll skips while `document.hidden` or when the active tab isn't Tickets; switching back to Tickets or re-focusing the page triggers an immediate refresh. Cuts thousands of pointless API calls/day per idle viewer. |
+| FO-OPS-01 | `src/index.html` | Missing-`API_BASE` fallback now targets the prod bridge (`fleetapi.rahamafresh.com`) per the documented design (was the staging bridge). |
+
+## Verification
+- Inline app script extracted and passed `node --check` (no syntax errors).
+- Modified Caddyfile passed `caddy validate` inside the deployed fleetops image on
+  twala ("Valid configuration").
+- 37 `esc(`/`escapeHtml(` call sites after the change (was 21, tickets-only).
+
+## NOT done — operational
+1. Deploy flows through the Forgejo → Coolify webhook on push (staging first).
+   Before **prod** promotion, redeploy the prod `dashboard_api` bridge — it lacks
+   the INC/CRQ/fuel-fills routes this SPA version calls.
+2. After the staging deploy, click through all four tabs with DevTools open to
+   confirm zero CSP violations before promoting.
+3. Root scratch files (`marker-preview.html`, `tracksolid_db_connection.md`,
+   `webook_instructions.txt`) left untouched — decide keep/commit/delete;
+   `tracksolid_db_connection.md` should be rewritten for the SSH-tunnel workflow
+   once the public DB port closes.
