`punktfunk_connection_report_phase` (fa822744, coherence tail 1d31e4c5) and the
`PUNKTFUNK_CLIENT_CAP_PHASE_LOCK` mirror const (7cf71dd2) grew the embeddable C
surface without moving ABI_VERSION. Every prior additive entry in that doc list
bumped it — v3's wake_on_lan, v5's next_rumble2, v8's clipboard block, v13's
send_pen — precisely so an embedder can ask punktfunk_abi_version() whether the
function it wants to link is there. Left at 13, the one number that answers that
question said "no report_phase" about a core that has one.
The header was already regenerated with both symbols, so it carried the new
surface under the old number; the regen here changes exactly the #define and its
doc block and nothing else, which also confirms the committed header was
otherwise current.
Additive and capability-gated: the host arms on report receipt, the wire grows
only PhaseReport (0x32) — a control message an old host never reads — and a
strict-prefix append on the 0xCF host-timing tail, so WIRE_VERSION stays 2. No
in-tree caller compares ABI_VERSION against a literal; mgmt/tests.rs asserts
against the symbol.
Verified: cargo build -p punktfunk-core regenerates include/punktfunk_core.h to
exactly this diff; punktfunk-core lib suite 134/134; rustfmt clean. The C ABI
harness cannot run on this Mac (`ld: library 'opus' not found`, the documented
pre-existing local linker gap) — CI's Linux leg is the gate for it.
