1. Interview rulings — the full sequence

Three review passes ruled on this workshop's open items, in order. Each is recorded here as process history — the corrections across passes are not noise; they are exactly the kind of thing this document exists to make visible rather than silently overwrite.

Interview 1 (post round 1)

Full record: lead-interview-1.md. Ratified by silence: tagged-envelope migration triggered; viewport-sized canvases below the canonical tier; the T-1177 cliff representation (elevation + channel_depth

• cliff_edge); cache composition (server global tier + client FileAccess dir, compose not compete). Ruled: step ladder deferred to round 2's concrete tables; map time axis = current-state-via-TTL-split with the staleness-vs- storage eviction-axis distinction; cliffs sparse + Phase-4 scope; round 2 GO with measurement ⑥ run in parallel.

Interview 2 (post round 2) — two rulings that reworked the round-2 package

1. Ladder bottom narrowed from tile/voxel (1 m) to chunk (64 m). Jeroen, verbatim: "the actual tile level rung seems unusable. maybe replace with 64?" — reasoning: a full-screen Atlas view at 10 px/tile shows ~192×108 m of ground, which is in-world viewport content (Phase 5), not map content. This is a deliberate narrowing of the D-226(d) floor's interview-1 opening, not a reversal of it — block and chunk remain legal Atlas rungs under the viewport-sized carve-out; tile/voxel re-close, exactly as item (d) originally required, now scoped to the tier where the opening was never meant to reach. Dudley benched the never-measured chunk rung in response (dudley-interview2-response.md §1) and built Option D — the adopted ladder.
2. Seed-chaining ruled the OPPOSITE of Dudley's round-2 default. Jeroen answered NO to Dudley's round-2 "independent re-derivation, coarser rung called only as a nested function" ruling — he meant the finer step genuinely consumes the coarser step's resolved output. Reconciled without weakening D-227 via the cache-accelerated pure function model (§2 below; tyre-round2.md §(a.10)).

Both rulings triggered new measurement work (the chunk-64m bench, the S2 courses-density bench at chunk/block, the S4 TTL-cadence formula) rather than being filed as bare architectural pronouncements — consistent with this workshop's standing discipline of ruling from real tables, not principles.

Post-ratification review (after the as-built briefing)

Jeroen reviewed architecture-briefing-final.md (the plain-language as-built writeback he requested) and raised two further items:

1. Global-tier byte math was wrong. Round 2's ~174 MB figure had priced the canonical always-kept tier as a full District-spacing canvas (8.3M cells/body). Jeroen's own review caught that the opener is a variable, region-grid canvas (one gridunit per region, not per District cell) — correcting this produced a rung-identity split: rung 0 = Global (the variable, always-kept opener) and rung 1 = Region (the largest fixed, evictable rung) — previously conflated as one "step 0 = Region" tier. Recomputed against the real 267-body population: ~8.85 MB PNG-encoded, all bodies (not ~174 MB — roughly 20× smaller).
2. The lakes gap. Jeroen's direct question: "when filling basins to find an overflow, is that body flagged as lake or flooded or something? do we draw lakes on the map?" This surfaced a real gap (§4 below) and produced a genuine message-crossing between Araminta and Dudley, resolved convergently — documented in full as process history in §4.

---

2. Governance record — filing package (final)

D-255 claimed (architecture domain). One new record + twelve amendment texts, all record-ready as drafted in tyre-round2.md §(a).

#	Record	Type	Source text
1	D-255 — Body-map-viewer stepped render architecture	NEW	tyre-round2.md §(a.0)
2	D-166 corollary — per-step repoint (owns between-step magnification)	AMEND	§(a.1)
3	D-226 T-1143 ruling 2/3 — tagged-envelope + continuous-zoom superseded	AMEND	§(a.2)
4	select_rung / rung model — replaced by the discrete step index	AMEND	§(a.3)
5	D-243 — gridunit vocabulary entry (additive; Atlas floor = chunk)	AMEND	§(a.4)
6	D-226 T-1124 §2 windowed-family ceiling — tagged-envelope triggered, re-scoped	AMEND	§(a.5)
7	D-227 — map-time TTL-split + staleness/storage eviction-axis distinction	AMEND	§(a.6)
8	river-courses-t1170.md carrier rule + cliff sparse-list	AMEND (note)	§(a.7)
9	D-226(d) whole-body prohibition — per-request framing + client-cache accumulation cap	AMEND	§(a.8)
10	D-226 T-1143 ruling 1 — floor narrowed to chunk (tile/voxel re-close)	AMEND	§(a.8b)
11	D-227/D-192 — persistent client-cache schema/version tag	AMEND	§(a.9)
12	D-227 — seed-chaining as "cache-accelerated pure function"	AMEND	§(a.10)
13	D-227 — lakes sourced from settled hydrology; endorheic cue via outflow-course presence	AMEND	§(a.11)

Records confirmed surviving untouched (stated explicitly per Tyre's list, so the Clerk audit does not over-rewrite them): D-010 (four principles — the server relocation reinforces principle 4); D-166 cascade + phase gating (still Phase-4 Atlas); D-169/D-170 (implant UI, unchanged); D-223 (atlas_city_names, unchanged); D-239 (the frozen 17-zone morphology + vegetation/glaciation vocabulary — the lakes fix explicitly does not touch it, reusing the existing MorphologyZone::Lake discriminant and routing the endorheic cue through courses precisely to avoid an 18th zone).

D-record text: the full, final amendment text for every item above is authoritative in tyre-round2.md §(a.0)–(a.11) — this table is an index with citations, not a duplicate copy, per the project's single-source-of-truth convention for governance text (governance/README.md). Sync into governance/decisions/architecture.md via pql decisions claim D architecture "Body-map-viewer stepped render architecture" (already reserved as D-255) followed by pql decisions sync.

3. Architecture summary (as-built)

The full plain-language writeback is architecture-briefing-final.md — Jeroen's own outline, rewritten in the same style and brevity to reflect what actually shipped. Condensed here:

• Three locked premises, unchanged since the brief: server-side content determination (per-gridunit data canvases per zoom step), client as a pure map-art function (colorize/style/annotate, never invent geometry), stepped zoom (discrete rungs, cursor-anchored, no continuous zoom-scaled canvas).

• The Atlas step ladder — six levels, final (Option D):

  Rung	Level	Spacing	Canvas	Cost (parallel, measured)
  0	Global (opener, canonical, always-kept)	1 gridunit/region (variable, ~205 km)	body's own region grid, ~18K cells avg	~16–21 ms/body; ~8.85 MB PNG all 267 bodies
  1	Region	204.8 km	3840×2160 fixed	1,827 ms
  2	District	2,048 m	3840×2160 fixed	1,827 ms
  3	Quarter	512 m	3840×2160 fixed	~1,827 ms (same-band)
  4	Block	128 m	3840×2160 fixed	~1,827 ms (measured)
  5 (deepest)	Chunk	64 m	3840×2160 fixed	1,724–1,733 ms (measured)

  Bottom-out rule: 1 screen px per 64 m gridunit, no magnification margin (the old 10×-per-tile legibility margin does not apply — a chunk-scale feature is already legible at 1×1). Tile/voxel (1 m) is Phase-5 in-world content, never Atlas-mapped. Every fixed row is directly measured; rung 0 is measured too (Dudley's bmv_global_tier_bench.rs).

• Wire: tagged-envelope carrier (StepCanvasRequest/StepCanvasResponse, a sixth discriminated Inbound variant extending an already-five-times- proven pattern in server/src/bridge/mod.rs). 8 dense fields (6 static + 2 sim-state) PNG-per-field, 2 sparse lists (courses, cliffs) MessagePack-native. No water field — lakes ride the existing MorphologyZone::Lake (§4).

• Cache: three tiers — client in-memory LRU → client disk FileAccess (two independent sweep axes: staleness for sim-state, storage-budget for everything else) → server (Tier 1 rung-0 resident resource, ~8.85 MB all bodies, keep-always; Tier 2 sub-global geometry, storage-evicted on time-since-last-visit). Sim-state TTL bound to 1× the field's own fastest driving sim-clock bucket (tidal-or-seasonal for flooded, seasonal for glaciation) — a formula, not a fixed number, confirmed cost-affordable at 1× with no multiplier needed.

• Client render: RTT terrain layer, CPU Image.set_pixel colorize (confirmed cheap at realistic canvas sizes by measurement ⑥, ~78 ns/cell flat) + unscaled screen-space annotation layer, replacing _canvas.scale and the entire _zs()/_zs_stroke()/_zs_ring_radius() compensation family by construction.

• Seed-chaining: cache-accelerated pure function — a finer rung's derivation may read a resident coarser rung's continuous baseline as an optimization (falling back to fresh derivation when not resident); the ①②③ benched costs remain valid as the cache-cold worst-case ceiling. A mandatory cache-hit == cache-miss byte-identical determinism test is the correctness gate.

• Lakes: sourced from HydrologyResult's settled equilibrium, riding the existing MorphologyZone::Lake — zero new wire fields, zero vocabulary change (§4).

---

4. Process history — the lakes arc (documented in full, not condensed away)

This is recorded at length deliberately: it is a clean example of the workshop's own discipline working correctly under a genuine, in-flight message-crossing, and the coordinator specifically asked that it be preserved as process history rather than silently resolved into a single final answer.

The catch. After reviewing the as-built briefing, Jeroen asked directly whether basin-filling from settled hydrology gets flagged as a lake on the map at all. Checked against the real code (not assumed): the gap was more specific than a missing field. MorphologyZone::Lake (discriminant 1) already exists in the frozen 17-zone vocabulary — the gap was a missing data source. Today's Lake emission comes from a crude heightmap threshold (ocean_fraction_q >= 60, a bilinear sample of the raw below-sea-level mask) with zero connection to HydrologyResult's settled basins — a gap the code's own comment already flagged as known, just never connected to the solver this workshop's own measurement ① is about.

The crossing. Dudley answered the coordinator's routed lake-schema question with a proposal for a new water: Vec<u8> dense field ({None, Lake, Sea}), reasoning from first principles about wire cost and vocabulary freezing. Independently, in flight, Araminta specced her own water: Vec<u8> field with the same shape and posed three questions back to Dudley (endorheic-carrier sizing, pipeline slot, struct reconciliation). Dudley answered those three questions fully (visible in his document as §1–3 under "LAKES CONVERGENCE," including a full crossover-cost bench comparing a sparse Vec<LakeBasin> list against the dense water field across the real 267-body basin-size distribution).

The resolution. Later the same day, both Dudley and Araminta independently discovered the better answer and converged on it without either conceding to the other: fold lake/sea classification into the existing MorphologyZone::Lake discriminant instead of adding any new field at all. Araminta reached this by re-verifying Dudley's own code-read directly against source (district_profile.rs:556-565, generator.rs:1198- 1223, features.rs:104-105) and recognizing her own original objection (that folding into morphology would require widening a frozen vocabulary) was built on a false premise — the vocabulary entry already existed; only the data source was missing. Dudley reached the same place from his own post-ratification code investigation. Both documents mark the earlier water-field material explicitly as SUPERSEDED-BY-CROSSING rather than silently deleting it — Dudley's document states plainly: "it isn't one of us conceding to the other, it's convergent verification."

What survived the crossing unmodified: the pipeline/projection ruling (sample HydrologyResult's continuous filled_scaled field bilinearly per rung — never project discrete basin-cell membership, which would produce a blocky, non-refining lake edge, exactly the magnified-coarser-composite artifact D-166's corollary forbids). This reasoning is agnostic to which field carries the result, so it applied unchanged to both the abandoned water field and the final morphology-fold.

Final, converged answer (D-227 amendment §(a.11)):

• Lakes ride the existing MorphologyZone::Lake — zero new wire field, zero vocabulary change. The fix is a data-source correction: derive_morphology_zone sources Lake from settled hydrology's continuous filled_scaled field (sampled bilinearly, the same mechanism ocean_fraction_q/sea_level already use), falling through to today's heuristic where no basin exists.
• Lake geometry is static (a pure function of seed + terrain, cached indefinitely-fresh), explicitly distinct from Araminta's sim-state flooded plane — a lake's existence doesn't flicker on the seasonal TTL.
• Endorheic-vs-overflow cue: outflow-course presence, zero wire bits, zero new zone. Dudley's original crossover-cost analysis (dense-bit vs. sparse-list) was correctly identified by the coordinator as not actually answering this question — both of those carriers were foreclosed once the morphology-fold landed. The real choice was reasoned fresh: an overflow basin's guaranteed non-empty outlet_path becomes a visible exit river in courses; an endorheic basin's absence of one is the honest "no drain" signal. Three reasons this wins over a dense vocabulary bit: proportionality (endorheic is 4.63% of real basins — too rare to justify a permanent 18th MorphologyZone arm every consumer inherits forever), the outlet-wiring work is required regardless (an overflow lake must show its exit river to be hydrologically honest — the cue is a free side effect, not a feature built to carry it), and the inference is definitionally sound with no misfire case (every Overflow basin has a guaranteed outlet path, every Endorheic basin has none — tested directly: overflowing_basin_has_nonempty_outlet_path).
• Honest sequencing stated plainly, not glossed over: until the basin-outlet→D8 wiring ticket ships (pre-cleared as additive by T-1170 Ruling 7b's reserved TERMINAL sentinel), the map shows lakes but not the drains-vs-closed distinction. This is not a design gap — it is two distinct, sequenced deliverables, and the outcomes record states which one ships first rather than implying the distinction arrives automatically the day the sourcing fix lands.
• The originally-proposed cliffs-based endorheic cue was independently ruled out by Araminta after directly re-checking the population survey: zero carved cells across all 267 real bodies means a cliff-wired cue would never fire in practice.

5. Deprecation sweep

DQR records (13 dispositions — the 12 amendments in §2 plus D-192's cross-reference note; full text in tyre-round2.md §(d)):

Record	Disposition
D-166 corollary (2026-07-21)	AMEND — repointed per-step, not deleted
D-226 T-1124 §2 ceiling	AMEND — re-scoped to the legacy district_window carrier only; re-scope is final, the conditional supersede branch does not fire
D-226 T-1143 ruling 2	SUPERSEDE — tagged-envelope migration now triggered
D-226 T-1143 ruling 3	SUPERSEDE for transport (stepped); cursor-centering/edge-scroll/full-reset survive

D-192 (no version handshake)	CROSS-REF note — the co-ship guarantee does not extend to the persistent disk cache
river-courses-t1170.md (Ruling 1c)	AMEND (note) — terminology repoint + cliffs as rule (iii)'s second vector member

Surviving untouched: D-010, D-166 cascade/phase gating, D-169/D-170, D-223, D-239 (see §2 for the explicit no-touch statement on each).

Tickets (10 dispositions):

Ticket	Disposition
T-1176	CLOSE as delivered — this workshop is its output
T-1158	CANCEL with supersession note — the canonical-frame cluster it wanted to extract is exactly what the stepped model deletes
T-1175	RE-SCOPE, unblocked — the c1 blocker (measurement ⑥) is discharged; tapering lands on the new screen-space annotation layer
T-1157	RE-SCOPE as the stepped mechanism's capture harness — the dead-goldens problem it targets is a direct consequence of the split the stepped model collapses
T-1174	KEEP unchanged — a derivation-correctness bug orthogonal to the render pivot, priority raised (more derive paths now share the same position math)
T-1153	stays done; shipped code (_view_zoom, continuous-zoom transport) on the _canvas.scale retirement path
T-1152	stays done; compute_tile_grid() mosaic superseded by the rung-0 Global canvas
T-1153/T-1152 test suites	retired with their code; replaced by re-scoped T-1157
NEW — lake morphology sourcing	CREATE — source MorphologyZone::Lake from HydrologyResult's filled_scaled, self-contained, no wire change
NEW — hydrology basin-outlet → D8 wiring	CREATE — thread overflow basin outlets into RiverNetwork/courses; pre-cleared additive by T-1170 Ruling 7b; this is the ticket the endorheic cue ships on

_canvas.scale retirement path (explicit list for the implementation ticket, full text tyre-round2.md §(d)): _canvas.scale/_canvas.position/ _apply_transform(); the _zs()/_zs_stroke()/_zs_ring_radius() compensation family; select_rung()/MAX_COVERAGE_M/compute_tile_grid(); the AtlasViewer/orbital-mosaic-vs-window split (collapses to "the Global opener is rung 0, one path"); _view_zoom/_canonical_fit_zoom() (replaced by the discrete rung index + the rung-0 canonical frame).

Clerk consistency audit: the known-conflicts starting set above (13 DQR + 10 ticket dispositions) is the complete, agent-produced sweep. A systematic audit pass beyond this named set is the standing pre-dismissal check per the brief's Expected Output 2 — run against the filed governance/decisions/ architecture.md text once D-255 and the twelve amendments are synced, to catch any conflict the delta did not explicitly name.

7. Adversarial pass disposition (Troblum)

Final scorecard (troblum-round2.md FINAL UPDATE): of seven original findings (2 BLOCKING, 5 SERIOUS), all seven are resolved by the time of filing:

Finding	Resolution
B1 (population-scale cliff survey never run)	RESOLVED — 267/267 real bodies surveyed, 0 carve
B2 (seed-chaining fork unresolved)	RESOLVED — interview-2 ruling + Dudley's source-verified cache-accelerated model
S1 (evict-then-revisit costing)	RESOLVED (mechanism) — both cache specs converge on dropping distance_decay; end-to-end revisit number correctly deferred as tuning
S2 (courses-density coverage gap)	RESOLVED — Dudley's chunk/block courses bench, real finding, filed
S3 (D-226(d) letter vs. purpose)	RESOLVED — per-request framing + client-cache accumulation cap, §(a.8)
S4 (sim-state phase cadence unnamed)	RESOLVED — Dudley+Araminta joint formula, 1× confirmed affordable
S5 (disk-cache version tag)	RESOLVED — §(a.9), complete fix

N1 (units convention), N2 (informational), N3 (clean bill) — all closed or never live concerns. No finding required walking back a round-1 or round-2 position; every fix Troblum checked against primary source held up exactly as documented.

8. Diagrams

Pending — to be created via /d2-diagram in docs/diagrams/architecture/ following the standard post-filing diagram pass:

• Step-ladder diagram (Global opener → Region → District → Quarter → Block → Chunk, with the variable/fixed and canonical/evictable seams marked).
• Cache-tier diagram (three tiers, the two eviction axes, the rung-0/rung-1 seam).
• Wire-envelope diagram (tagged StepCanvasRequest/Response vs. legacy district_window, the re-scoped ceiling boundary).
• Lakes data-flow diagram (HydrologyResult → filled_scaled bilinear sample → MorphologyZone::Lake → courses outlet presence → endorheic cue), given the arc's own complexity documented in §4 above.

Not yet started — first post-filing task, per standing practice (diagrams follow filed decisions, not the reverse).
