feat(analytics): identify the companies browsing the site

[ashrafsamhouri]

Adds /admin/companies — which organisations are on the site, what they looked at, and whether they are in the pipeline.

Company-level only: the Clearbit-Reveal shape, explicitly not the RB2B person-level one, which would destroy the legitimate-interest basis the analytics tables rest on.

This is safe to merge as-is

With IPLOCATE_API_KEY unset (the default), no IP address reaches any third party. The page shows country data — already covered by existing analytics disclosure — plus companies that self-identified by typing a work email into a form they chose to fill in. Nothing new is disclosed to anyone.

So the recommended path is: merge now, switch on after the privacy policy is updated.

To switch network identification on

Order matters. runtimeConfig bakes at build time (documented in .env.example) and the deploy builds from the environment, so the vars must exist before the deploy that enables them — otherwise the feature ships dark and needs a second deploy. NUXT_IPLOCATE_API_KEY overrides at runtime without a rebuild.

Var	Purpose	Notes
IPLOCATE_API_KEY	IP → company	iplocate.io, free 1,000 lookups/day
BRANDFETCH_API_KEY	size / industry / HQ	Already used for logos — please confirm it is set in prod. Without it companies are identified but have no firmographics to filter on
IPLOCATE_DAILY_BUDGET	optional	Defaults to 900

Before setting IPLOCATE_API_KEY, publish the privacy disclosure. Paste-ready copy and a pre-publish checklist are in docs/privacy-company-identification.md. The policy is CMS content (singletons, key privacy) edited at /admin/pages, so it can't ship in this PR — but the copy is written and reviewable.

008_firmographics.sql runs in the PRE_DEPLOY job. IF NOT EXISTS throughout; the one ALTER TABLE adds a nullable column (instant, no rewrite).

How it works

Waterfall in server/utils/company.ts: self_reported (work email on /sales — certain) → ip (IPLocate → domain, enriched by Brandfetch) → asn → nothing.

Cost control is the design: a gate (high intent, or a second page view, counted in-process so it adds no query), a free reverse-DNS pre-filter rejecting consumer/hosting networks before any paid call, network_verdict so each telco is paid for at most once ever, then per-day and per-domain caches. An office of forty costs one lookup a day; Comcast costs one lookup in total.

Firmographics reuse the existing Brandfetch call, which was already fetching and discarding employee range, industry and HQ. No new vendor.

Conversion is answered twice, deliberately

• Converted on site — same-day form_submitted. Closest to causal, but a floor: the hash rotates at UTC midnight, so browse-Tuesday-convert-Friday is invisible.
• In the pipeline — companies.domain ⋈ sales_leads.email_domain. Domain-to-domain, never touching visitor_hash, so the 006 contract holds. Complete across all time but not attribution; leads predating the visit are marked "earlier".

No lead yet sorted by intent is the outreach list.

Verified

• Migration applies; every query runs against the real schema.
• Lead join tested against the 11 real lead domains — 11/11 match, complete/partial derive correctly. The lead subquery is pre-grouped so it structurally cannot fan out and inflate event counts.
• IPLocate tested live: IBM, Siemens, Ford, MIT, Stanford, USGS identified; Comcast, AWS and GitHub-edge correctly skipped.
• Brandfetch parser checked against Brandfetch's own documented schema — caught two defects, both fixed in d7b8084: kind is an enum (PRIVATELY_HELD) that would have printed raw, and employees is an integer, not the range string the comments claimed.
• Reverse-DNS classifier tested on real IPs — caught a false positive (GitHub's LB embeds its IP like a dynamic pool) that would have silently skipped corporate networks.
• Confidence ladder upgrades ip→self_reported and refuses the downgrade.
• Build, types, format, knip clean.

Not verified

• The authenticated page render. Verifying it needs an admin session, and both routes to one were correctly blocked by security controls (forging a session row; reading a live OTP from logs). The template compiles and the endpoint builds, but no one has seen it render with rows. Worth a look on first login.
• Expect a thin match rate (single- to low-double-digit % of looked-up visitors), weighted to corporate networks. The page states its denominator out loud.
• The widened gate will spend more lookups until network_verdict converges; the budget cap logs when hit.
