87a4803bde [lane A+B+C] L3 Stomach: the acid sea, and pH as a resource you can see
The last skeleton. L3 has been 4 events since round 1, waiting (in its own status field) on
"the pH field" and a boss framework; both exist now, so the level is authored: 46 events,
2500 units, the sea, and the Guardian at the end of it.

THE PH MECHANIC, finally load-bearing. Lane A built an acid plane in round 2 and left two
hooks on it — depthAt() labelled "B:" and set() labelled "C's event pump drives this" — and
nothing had ever called either. Now:
  - player.js scales the biome's ambient coat drain by SUBMERSION. Stomach 2.2/s x5 = 11/s
    under the surface (measured: 8/s net of regen, and regen is off for 2.5s after any hit,
    so it is brutal mid-fight); x0.15 above it, which is effectively safe air.
  - a new `acid` level event names a target height and boot eases the sea toward it in step(),
    so a RISING TIDE is a beat C can author. L3 uses two: -14 -> -6 mid-sea, then -6 -> +2 in
    the antrum, where the surface goes ABOVE the centreline and the safe lane simply stops
    existing. Measured: the identical spot (y -5) goes from 0/s to 9.67/s across that tide.
This is the GDD's "mucus shallows are safe lanes" expressed as DEPTH rather than wall-hugging,
which is better on two counts: it reads instantly (you can SEE the surface) and it makes the
vertical axis matter in the one level that is a room. Every collectible worth having is under it.

Gated on the sea's s-span, not on depthAt alone — depthAt returns a bare -1 outside the span
and that is indistinguishable from "1 unit above the surface", so reading it naively would have
quietly scaled ambient drain on every level in the game. Caught before it shipped.

Level: cardia (still teal, so the fundus can REVEAL the sea) -> fundus (the teaching room:
huge, low tide, nothing kills you fast) -> body (the sea proper, tide rises while you are in
it) -> antrum (no safe air left, only speed) -> pyloric antrum (the Guardian). H. pylori is
taught alone in the dome and tested in a rising sea; pepsin swarms scale 3 -> 6; bezoar_chunk
is a new catalogue row for the stomach's traffic.

L3 has NO commensals and no biofilm gate, which is anatomically exact — acid sterilises, which
is why H. pylori is famous for surviving it. So BIOME STANDING goes quiet for nine minutes and
comes back in L4, which makes L4's colonies read as relief rather than furniture.

C's sim: par 540s vs par-pace 555s ("requires pushing above par-pace"), pressure
3.75/1.50/2.44/2.16, min clearance 7.15 vs the 2.5 law, all 21 checkpoint gaps under 30s.
par.score corrected 9000 -> 5500, because 9000 was above everything the level can actually pay.

Deferred, and said out loud rather than quietly dropped: churn cyclones. A vortex that flings
the player is a FORCE and no hazard in the tree applies one; it wants the same A/B work as the
Guardian's arena churn and should land with it.

a318cf09f7 [lane B+C+F] The Appendix Sovereign: the secret boss, and a reputation you cannot fake
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.

1e4775ab12 [lane C] L4 Small Intestine: the long maze — the campaign doubles in length
The first new level since L2, and the campaign's endurance beat. 7 segments, 6000 units,
63 events, ~10 minutes. Authored entirely from systems that already exist — no new engine work.

The three acts are anatomy, not invention: duodenal bulb -> descending duodenum (the ampulla,
where bile enters) -> jejunum -> deep jejunum -> ileum -> terminal ileum -> ileocecal valve.
Giardia really colonises the duodenum/jejunum and Peyer's patches really concentrate in the
ileum, so the difficulty curve IS the gut's own immune gradient: you fly from the quiet
absorptive end into the lymphoid end and the walls get angrier.

Identity vs L2: flow 8-10 against L2's 12-20, curviness up to 0.70, fog 0.050. L2 punishes bad
reflexes; L4 punishes bad reading. Segmentation ring gates (the small bowel's real motility)
teach at 70% open and test at 43% in an 8-unit lumen.

Three catalogue rows carry the new fiction onto existing archetypes — chyme_clump (floater),
neutrophil_hunter (seeker), bifido_colony (flora). The ileocecal biofilm gate at s5500 is the
first time the reputation loop pays out at a level's END rather than mid-level.

C's own tooling verifies it: selfcheck 4/4 valid, and --sim reports par 600s vs par-pace 576s
("par is reachable at par-pace throttle"), a pressure curve of 1.00/1.43/1.90/2.46/1.65/2.69/
1.63, min clearance 3.62 vs the 2.5 law, all 22 checkpoint gaps <= 29.3s. Driven end-to-end
in-engine: all six entity types spawn, biofilm fires at 5500, valve gate completes to L5.

The GDD's Tapeworm miniboss is not here — no boss framework exists yet. It goes in at ~5500
when that lands; the level notes say so.

3c059f20db [lane B+C+F] The biofilm gate: the reputation cash-out, "it helps you in level 5" made real
The deeper payoff of the flora loop. A new `biofilm` level event: cross one and combat checks
BIOME STANDING — high enough (>= need), the native flora PART the biofilm, budding a wave of phage
allies + refilling coat, then spending the goodwill; too low, it stays sealed and you run the
gauntlet raw. Emits `biofilm {opened}` so E can voice both.

- combat/index.js: biofilmGate(ev) on the level:event pump (fields need/allies/coat).
- levels/index.js: the selfcheck knows the `biofilm` type now (validates need 0..100).
- L2: one demoed at s2500 — the opening flora/akkermansia/beacon let you BANK standing, and the
  gate cashes it into a phage escort right before the hiatus + reflux finale.

The mechanism is complete; L5 also gets the fast-route/Appendix branch when that level + world
support land. Verified in-engine: high standing -> opened, 3 phages, coat 50->90; low -> sealed.

2e85ec0622 [lane C] Round 2 WIP (session cut off): schema v2, surf-aware pacing, chase analysis, --probe
Landed before the cut: schema v2 (segments[].wave.amp override, validated — breathe stays
biome-owned); hiatus re-authored tight AND calm (radius back to 6.5, amp 0.6, 3.3u steady
clearance); par 210 -> 180 with full rationale (below throttle-only par-pace, above a surf
run — the medal teaches the mechanic); finale surge 21 -> 24 so surfing is the stylish
escape (required 1.20x); surf profile reads A's live CREST_FACTOR; chaseAnalysis() +
escapability laws in validate; NEW --probe builds A's real canal and measures clearance
against the model (all L2 segments clear the 2.5 floor, hiatus 3.75); isMain guard +
importSpline shim — fixes A's selfcheck process.exit killing C's mid-run (qa.sh had been
green on one level out of three).

Cut off before: fly-through of the integrated build (blocked on B), pickup economy handover
(B proposed numbers in balance.js meanwhile — reconcile), L1 encounter design doc, GDD boss
folding, NOTES. Committed by F to protect the shared tree; levels selfcheck 3/3 GREEN.

1b5ec767cd [lane C] Round 1: schema v1, levels registry + selfcheck + pacing sim, L2 vertical slice
Data spine:
- Schema v1 ratified (TECH.md, C-owned). Additive over v0: schema/par/next, segment
  name, cross-section placement (theta/rho as a FRACTION of safe radius), spread, span,
  pickup+gate event types, hazard params. STUB_LEVEL synced (that const only, per
  ROUND1 §Lane C.1) — world.hash() unchanged (1bdf001), geometry provably untouched.
- levels/index.js: registry + loader (node+browser, no THREE), real schema selfcheck
  (qa's --selfcheck hook is now live) and a pacing simulator (--sim). Consumes the other
  lanes' contracts live rather than restating them: A's biomes.js for ids and
  wave.amp+breathe, A's SKIN, B's tuning.js hull radius, B's balance.js for scores.
- levels/enemies.js (fiction id -> archetype join table), levels/difficulty.js.

L2_esophagus — the vertical slice, complete: 3600 units, 7 beats, 47 events, 65 enemies,
10 checkpoints, 3 samples, reflux-surge finale. L1/L3 skeletons (shape only).
Anatomy is the level designer: the three real esophageal constrictions are the three
setpieces, and all three enemies are real esophageal pathology (bolus chunk, eosinophilic
esophagitis, candida esophagitis).

Measured (node web/js/levels/index.js --selfcheck|--sim; qa GREEN):
- selfcheck 3/3 valid, exit 0.
- pressure curve 0.27 -> 2.14 -> 4.35 -> 0.69 -> 4.53 -> 6.35 -> 4.40 (breather/pressure/
  spike/breather/pressure/peak/finale).
- par 3:30 vs measured 2:47 speedrun / 3:19 par-pace / 4:22 timid; par.score 9000 of a
  9400 kill budget (95%), computed from B's scores.
- all 10 checkpoint gaps within the <=30s death-cost law (max 28.8s); min clearance 2.73.

Two contract collisions found and resolved (LANE_C_NOTES):
- Biome ids: authored mouth/pharynx/cardia/pylorus; A's registry has six canonical ids and
  rejected all four. A is right — biome = look, segments[].name = anatomy. Conformed.
- Balance: my first enemies.js restated hp/size/speed/score that B owns in balance.js.
  Cut to a join table; index.js reads B's scores via scoreFor().

Caught live: A raised esophagus wave.amp 0.9 -> 1.4 mid-session, making the diaphragmatic
hiatus unflyable (2.33 vs the 2.5 floor). Widened 6.5 -> 6.8. The invariant also failed my
own aortic constriction's first draft (radius 7, symmetric squeeze) -> radius 9, directional.

No in-engine flythrough: ?stub=1&lvl= does not compose (snippet offered to F) and the stub
is single-segment, so it could only render beat 1. The pacing evidence is a kinematic model,
not a playtest — it proves L2 is flyable, paced and survivable, not that it feels good.
