-"""Check every `foo.rs:N` / `foo.rs:N-M` / `web/config.js:N` line anchor in the docs.
+"""Audit the docs' source anchors against the working tree.
 
-Paths may be bare (`notify.rs:320`, resolved under `src/`), prefixed with a directory
-(`src/domain/jmap/client.rs:108`, `cloudflare-worker/src/backends.js:9`,
-`web/config.js:585`), or unprefixed JavaScript (`config.js:585`, resolved under `web/`
-or the Worker).
+For every "`src/foo.rs:123`" style anchor in the docs, check that the file
+exists, the line is in range, and the line is not blank.
 
-LIMITATION: this only proves the cited line *exists and is not blank*. It does
-not prove the line contains what the prose claims about it. A doc can pass this
-audit with anchors that point at the wrong line -- a human must read the target
-line to catch that. Keep this in mind when quoting "0 errors" as proof of
-accuracy: it proves reachability, not correctness.
+LIMITATION: this only checks that the anchor TARGETS A REAL, NON-BLANK LINE.
+It does not check that the line says what the doc claims.
+A doc could say "foo.rs:123 defines get_by_key" when line 123 is actually
+`fn get_by_name`. This audit would pass.
+Someone still has to read the anchors to verify they're accurate.
 
-The one exception is a *phantom identifier*: if a backticked name sits right next
-to an anchor (the common "`foo` ... `bar.rs:N`" phrasing) and that name appears
-nowhere in bar.rs, the anchor is reported. Existence, not position -- the symbol
-may still be on the wrong line.
+The one exception is a *phantom identifier*: if a backticked name sits right
+next to an anchor, we check the name actually appears in that file. Catches
+docs claiming an identifier that doesn't exist.
+This is a loose substring check, so it has the same limitation as the anchor
+check above. It catches the obvious case but not a near-miss name.
+
+Two shapes of claim live next to an anchor, and they are checked with
+deliberately different strictness:
+
+  - Numbered anchor (`src/state.rs:283`). Kept as a loose substring check on
+    the member name. PAIR's EXT only matches a name followed by a colon and a
+    line number, so the anchor already pins down the location and the reader
+    can verify the line. Widening the verdict here would change the count of
+    findings in this branch, i.e. perturb the established baseline, for no
+    gain: any doc written next to an anchor names the place and the name.
+  - Bare file name (`src/channel.rs`, no line number). Checked with the strict
+    `member_present` test and reported as a `phantom member`. No line number
+    means the reader has nothing to verify, so the only thing this check can
+    prove is that the named member actually exists in the file. And a loose
+    test provably fails here: a doc can write `TelegramClient::send` and
+    satisfy a substring -- even a word-boundary -- test twice over, because
+    `channel.rs` contains `send_text` and reqwest's `.send()` is `send` at a
+    word boundary. Hence definition/unqualified-reference semantics.
