Two boss specs written to C's format (LANE_C_NOTES §Boss specs, round 3 additions) and the
first of them built. Both extend the roster along C's own law — one boss, one pressure — onto
the two axes the game had systems for and no boss pointed at: reputation (§4 Sovereign) and
restraint (§5 Mast Cell, specced only).
THE SOVEREIGN. The appendix is not vestigial: it is a biofilm reservoir where the gut's flora
shelter and re-seed the colon after a purge, and the whole fight is that fact. It is the only
boss whose existence is decided before you arrive — read once on entry:
karma >= 70 THE COMMUNION — no fight at all. Full coat, a permanent phage escort. The
reward for five levels of restraint is being spared a boss.
karma >= 30 THE TOLL — P1 only.
below THE SOVEREIGN — three phases. P1's matrix is immune to the cannon and only the
antacid torpedo disperses it (a mature biofilm's whole defining trait); P2 is a
quorum bloom that re-armours when the room gets crowded; P3 is a 20s reseed run.
And the mechanic that makes it this boss: the lair is seeded with YOUR OWN FLORA, and it feeds
on dysbiosis — every commensal your stray fire kills re-armours a plate, live, mid-fight.
KARMA vs STANDING — a real bug found in testing, and worth the extra number. `standing` is a
SPENDABLE meter: a full bar is consumed to bud an ally, dropping to a 50 floor. That meant a
perfect player could never HOLD >= 70, so the Communion was almost unreachable — verified: a
symbiotic pilot showed standing 50 and was demoted to "toll". `karma` is the same inputs with
nothing spending it. The Sovereign's tier and gates' `secretTo` branches read karma; E's bar
still reads standing.
Also: boss.js generalised to a registry, which was the claim its header made — the Sovereign
needed zero changes to enemies.js. LS_appendix (3 segments, 800 units, 16 events), reached from
L4's ileocecal valve via `secretTo`/`secretNeed` — anatomically exact, the appendix hangs off
the cecum right past that valve. The secret is hidden behind conduct, not behind a wall.
C's selfcheck caught par.time as a free medal and the fix improved the design: par 160 sits
under the timid traversal, so only a Communion run (which has no fight) can beat it. The time
medal rewards the same conduct the level is about.
Verified: all three tiers branch correctly (communion = 0 nodes + 4 phages; toll = 1 phase;
full = 3 phases, 4 armoured); killing a commensal mid-fight re-armours a plate (reason
"dysbiosis"); the valve routes karma 100 -> LS_appendix and karma 0 -> L5. Levels 5/5 valid.
