Map aliases for redirect targets + CC BY-SA 4.0 attribution (#730)

Browse Source 
* README: declare base_reverse_dns_map.csv under CC BY-SA 4.0

The map is now a curated derivative of the bundled IPinfo Lite MMDB
(as_domain / as_name fields, walked for unmapped operators and
classified via the workflow in AGENTS.md). IPinfo Lite is licensed
under Creative Commons Attribution-ShareAlike 4.0, which propagates
to derivative works, so the CSV is distributed under CC BY-SA 4.0
with attribution to IPinfo for the underlying network identification
data.

Also updates the file-size estimate in the README from "over 1,400"
to "over 5,000" to reflect the current state.

* Alias redirect targets into the map and codify the practice in AGENTS.md

When a domain's homepage redirects to a different host *for the same
operator* (acquisition target's site, or a TLD/subdomain variant), PTR
reverse-DNS reports observed in the wild may reference either domain.
Mapping only the original loses attribution for the redirect target.

Adds 91 aliases discovered during the previous bulk PR's classification
work — every redirect target where the original was newly mapped, the
target wasn't already in the map, and the target was the same operator
(not a sister brand and not a placeholder/bot/parking page). Notable
examples: apogee.us + boldyn.com both -> Boldyn ISP; sungardas.com +
1111systems.com both -> 11:11 Systems MSP; vodafone.is + syn.is both
-> Sýn ISP; sendinblue.com + brevo.com both -> Brevo (Sendinblue)
Marketing; tigo.com + millicom.com both -> Tigo ISP; rockwellcollins.com
+ collinsaerospace.com both -> Collins Aerospace Defense.

Codifies the alias-target practice as a new paragraph under AGENTS.md
step 6 (the homepage-redirect disambiguation rule). Key guardrails:
- Alias only for case 1 (acquisition) and case 3 (TLD variant). Do
  NOT alias for case 2 (sister brand / shared infra) -- aliasing the
  redirect target there mis-attributes the redirect target's email.
  Cited example: do not alias ziggo.nl to UPC after the chello.sk fix.
- Skip generic-placeholder, bot-management, and TLD/eTLD redirect
  targets (example.com, perfdrive.com, umbler.com, co.uk, com.br...).
- When in doubt, drop the alias rather than commit it. A missing alias
  is recoverable; a wrong one mis-attributes mail.

Also fixes four canonical-naming inconsistencies surfaced during the
brand-mismatch sweep, aligning recent additions to pre-existing entries:
- ga.gov: "Georgia Government" -> "State of Georgia" (matches existing
  georgia.gov)
- goco.ca, radiant.net: "Telus" -> "TELUS" (matches existing telus.com)
- vee.com.tw: "VeeTime" -> "VeeTIME" (matches existing veetime.com)

* Promote 21 inbound-redirect aliases from KU to map

Sweeping the session's collector TSVs for the inverse pattern of the
91 outbound aliases in commit ddf962e: domains that stayed in
known-unknown this session but whose homepage final_url redirected to
an entry that's now in the map. These are acquisitions and TLD/
subdomain variants where the operator can be inferred from the
redirect-target's existing mapping.

Notable acquisitions surfaced:
- nitelusa.com -> Comcast (NITEL was acquired by Comcast Business)
- level3.net -> Lumen (Level 3 rebranded)
- novis.pt -> NOS (Novis acquired by NOS Portugal)
- oxfordnetworks.net -> FirstLight Fiber (acquisition)
- saunalahti.fi -> Elisa (acquisition)
- omnicity.net, wcoil.com -> Watch Communications (acquisitions)
- servercentral.net -> Summit (acquisition)

TLD / subdomain variants:
- as29550.net (Simply Transit ASN domain) -> Simply Transit
- asahi-net.or.jp -> ASAHI Net (.jp variant)
- cyber-folks.pl -> cyber_Folks (cyberfolks.pl)
- digicelsr.com -> Digicel (Suriname variant)
- edpnet.net -> EDPnet (.be variant)
- la.net.ua -> Lanet
- pair.net -> Pair Networks (pair.com)
- twlakes.net -> Twin Lakes Communications
- megamailservers.eu -> MegaMailServers (.com variant)

Cloudflare email/SMTP family:
- cloudflare-email.org, cloudflare-smtp.com/.net/.org -> Cloudflare,
  Email Security (matches cloudflare-email.com/.net, distinct from
  the bare cloudflare.com/.net which use SaaS)

Of 32 redirect-to-mapped hits in the session TSVs, 21 cleared the
same-operator bar. The other 11 were excluded as case-2-equivalent
redirects (homepage hosted on Google/Wordpress/Aruba), registrar
parking pages (Dynadot), or ambiguous brand relationships requiring
research beyond what the redirect alone could justify (frontiernet.net
-> yahoo.com from Frontier's 2017 email-services migration to Yahoo,
dido.com -> socket.net, evo.uz -> tps.uz, ncport.ru -> avantel.ru).
Those are flagged in the PR comment for follow-up review.

* AGENTS.md: document the inbound redirect-target alias sweep

After a batch lands, the same collector TSVs that drove the original
classifications are also the input to a free secondary pass: KU
domains whose final_url redirects to a host that's now mapped are
typically the inbound mirror of the outbound alias rule (step 6).
Each such pair is an acquisition or TLD/subdomain variant where the
operator is inferable from the redirect-target's existing mapping.

Adds a new bullet to "After a batch merge" describing the sweep and
the same case-2 exclusion list as the outbound rule (sister-brand,
generic hosting platform, bot-management proxy). Notes that the
sweep routinely surfaces 5-15% of the prior batch's KU additions as
legitimate map promotions, citing the actual examples that landed in
this PR (nitelusa.com -> Comcast, level3.net -> Lumen,
saunalahti.fi -> Elisa, oxfordnetworks.net -> FirstLight Fiber,
asahi-net.or.jp -> ASAHI Net, etc.).

**The disambiguator is the WHOIS, plus a quick check of whether the redirect target represents an acquisition.** If WHOIS still names a specific operator that is *neither* the redirect target *nor* the redirect target's parent group, that operator is current and the redirect is shared-infra (case 2 — use WHOIS). If WHOIS is *stale* and matches a pre-acquisition entity while the homepage unambiguously presents the acquiring operator, the homepage wins (case 1 — use new operator). The IP-WHOIS netname is *not* a tiebreaker here — see rule 5; if the netname doesn't match the domain name, it is not a corroborating source for any brand decision.
**Always alias the redirect target into the map alongside the original — except for the sister-brand/shared-infra case (case 2) where the redirect target is a different operator.** If the redirect lands on the same operator's primary domain (case 1 — acquisition target's site, or case 3 — TLD/subdomain variant), and the redirect-target's base domain is not yet in `base_reverse_dns_map.csv`, add it as a new row pointing at the same `(name, type)` as the original. PTR-side reverse-DNS reports may reference either the original or the new operator's domain, and both should resolve to the same attribution. Examples from this codebase: `apogee.us` and `boldyn.com` both → `Boldyn, ISP`; `vodafone.is` and `syn.is` both → `Sýn, ISP`; `sungardas.com` and `1111systems.com` both → `11:11 Systems, MSP`; `zoom.us` and `zoom.com` both → `Zoom, SaaS`. **For case 2 do NOT alias the redirect target** — the redirect was misleading infrastructure, the redirect-target operator is a genuinely different entity, and aliasing it would attribute its email-sending to the wrong operator (e.g. do not alias `ziggo.nl` to `UPC` after the chello.sk fix). When in doubt, drop the alias and add only the original; a missing alias is recoverable, a wrong one mis-attributes mail. Skip aliases when the redirect target is a generic placeholder (`example.com`, parking page, hosting-platform suspended-site page like `umbler.com` / `uni5.net`), a bot-management redirect (`perfdrive.com`, captcha proxies), or a generic TLD/eTLD that the heuristic over-reduced to (`co.uk`, `com.br`, `net.br`).
7. **Don't force-fit a category.** The README lists a specific set of industry values. If a domain doesn't clearly match one of the service types or industries listed there, leave it unmapped rather than stretching an existing category. When a genuinely new industry recurs, **propose adding it to the README's list** in the same PR and apply the new category consistently.
8. **Two corroborating sources, or the domain goes to `known_unknown_base_reverse_dns.txt` — never to the map.** This is the bright-line guardrail that keeps the map trustworthy. Two corroborating sources means two *independent* signals pointing at the same operator: typically domain-WHOIS registrant + homepage content, or homepage + an established third-party directory, or domain-WHOIS + MMDB `as_name` registered to the same entity. A single source — a self-described homepage with privacy-redacted WHOIS, an MMDB `as_name` with nothing else, an IP-WHOIS netname for a domain whose name doesn't match the netname (rule 5 above) — does **not** clear the bar. Routed-network scale is *context, not corroboration*: knowing an operator routes /14 of address space tells you nothing about who they are. When the bar isn't cleared, the domain goes to `known_unknown_base_reverse_dns.txt` instead of the map. This applies equally to bulk-TSV passes, MMDB coverage-gap passes, PSL-private-domain passes, and ad-hoc single-domain additions — there are no per-workflow relief valves.

- **Sweep the batch's collector TSV(s) for redirect-target aliases in *both* directions.** Step 6 of the unknown-domain workflow tells you to alias the redirect target alongside the original (outbound) when you classify a domain. The mirror sweep is the inbound direction: now that you've added new map rows, look at the same TSVs for *known-unknown* domains whose `final_url` redirects to a host that's now mapped (or has always been mapped). Each such pair is typically an acquisition (e.g. `nitelusa.com → comcast.com`, `level3.net → lumen.com`, `saunalahti.fi → elisa.fi`, `oxfordnetworks.net → firstlight.net`) or a TLD/subdomain variant of an existing entry (e.g. `asahi-net.or.jp → asahi-net.jp`, `cyber-folks.pl → cyberfolks.pl`, `pair.net → pair.com`, `digicelsr.com → digicelgroup.com`). Promote the KU domain into the map under the redirect target's existing `(name, type)` and remove it from the known-unknown file. **Apply the same case-2 exclusion as the outbound alias rule** — skip when the redirect target is a sister-brand under the same parent group (the WHOIS for the KU domain would name a different specific operator), a generic hosting platform serving the original's static page (`google.com`, `wordpress.com`, `aruba.it`, registrar parking), or a bot-management proxy. When in doubt, leave the domain in known-unknown and surface it in the PR for review. This sweep is cheap (the data is already in the TSV from the batch's collector run) and routinely surfaces 5–15% of the prior batch's KU additions as legitimate map promotions.
