The alias `effective_tld_names.dat` returns the same bytes and the same `ETag`.\n\n## File conventions (measured)\n- Lines beginning `//` are comments (4 096); 2 072 blank lines; **10 334 rules**. The first rule (`ac`) is at line 16.\n- Two sections, delimited by exact comment markers: `// ===BEGIN ICANN DOMAINS===` (line 13) … `// ===END ICANN DOMAINS===` (line 11 249), then `// ===BEGIN PRIVATE DOMAINS===` (line 11 251) … `// ===END PRIVATE DOMAINS===` (line 16 501). **ICANN: 6 950 rules; PRIVATE: 3 384 rules.** Everything in PRIVATE is operator-submitted (`github.io`, `execute-api.af-south-1.amazonaws.com`, …); registrable-domain logic that should treat `foo.github.io` as one site must include PRIVATE, cookie/certificate logic that wants only registry policy must stop at the ICANN marker. There is no per-rule tag — section membership is positional.\n- Rule forms: plain label (`com.ac`), **wildcard** `*.` (289 rules, e.g. `*.ck`, `*.nom.br`), **exception** `!` (**8 rules**: `!www.ck`, `!city.kawasaki.jp`, `!city.kitakyushu.jp`, `!city.kobe.jp`, …). An exception overrides a wildcard in the same tree. No rule carries trailing whitespace or an inline comment (0 rules contain a space).\n- **459 rules are non-ASCII Unicode labels** (`aéroport.ci`, `公司.cn`, `網絡.cn`, `网络.cn`) and **zero rules contain `xn--`**. A matcher that receives punycode hostnames must IDNA-encode the list (or decode the input) or it silently misses every IDN suffix.\n- Header comments include `// VERSION: 2026-09-24_13-26-36_UTC` and `// COMMIT: a179a48c…` (lines 8–9) and the instruction \"Please pull this list from, and only from https://publicsuffix.org/list/public_suffix_list.dat\".\n\n## publicsuffix.org vs GitHub `main` (same day)\n`raw.githubusercontent.com/publicsuffix/list/main/public_suffix_list.dat` (334 697 B) is **not byte-identical**: it lacks the `VERSION`/`COMMIT` lines, and it already contains `net.ac` and `org.ac`, which the published file does not — i.e. **`main` is ahead of the published list**. Tools that read from GitHub see rules before they are \"published\"; tools that read from publicsuffix.org get the versioned, stamped release. Do not mix the two, and do not treat the GitHub copy as the release.\n\n## Caching\nStrong `ETag: \"68fdfa477789df593de7e62e5f33333a\"` and `Last-Modified: Thu, 24 Sep 2026 13:26:44 GMT`; both `If-None-Match` and `If-Modified-Since` → **304**. `Cache-Control: public,max-age=86400`; the edge showed `age` up to 65 825 s, so an unconditional fetch can be ~18 h stale within the day. The GitHub raw copy has a different (sha256-style) ETag and `max-age=300`.\n\n## Probe\n```\ncurl -sS -D - -o psl.dat https://publicsuffix.org/list/public_suffix_list.dat | grep -iE 'etag|last-modified|content-type'\ngrep -n '^// ===' psl.dat                      # four section markers\ngrep -vc '^//\\|^$' psl.dat                     # 10334 rules\ngrep -c '^\\*\\.' psl.dat; grep -c '^!' psl.dat   # 289 / 8\ngrep -P -c '[^\\x00-\\x7F]' <(grep -v '^//' psl.dat)   # 459 non-ASCII rules; grep -c 'xn--' → 0\ndiff psl.dat <(curl -sS https://raw.githubusercontent.com/publicsuffix/list/main/public_suffix_list.dat) | head\n```\n\nHow observed: 2026-09-30, direct anonymous HTTPS (curl, custom User-Agent) against `publicsuffix.org` and `raw.githubusercontent.com`; line/rule counts and the diff computed locally with Python on the downloaded files.
