#000013 closed: v7-W spatial-temporal substrate paper + namespace

Three artifacts landing per ticket §4.1 closure criterion:

1. docs/_source/merkle-agi-v7w-spatial-temporal.rst (658 lines)
============================================================

Substrate paper for the third commitment substrate — sister to v7
(logic / math) and arborist v9.8 (language / claim-lattice). v7-W
commits derived spatial-temporal world-state: objects, relations,
events, places, agent traces, observations. Six parts + appendix:

  Part 1 — Introduction & motivation. The third-substrate gap;
           why v7 § 11 multimodal composition isn't enough.
  Part 2 — Substrate definition. Hierarchical-grid spatial
           discretization (S2 / H3 / octree); frame as committed
           object with explicit transforms; substrate-declared
           clock (single-agent) + Lamport (multi-agent);
           quantized centi-confidence (range opt-in); five
           canonical tuple-classes (object / relation / event /
           place / agent_trace) each with its own π*_w.
  Part 3 — Theorems. T1-W (state binding), T2-W (causal
           completeness), T3-W (frame-transform soundness),
           T4-W (ε at affine frontiers).
  Part 4 — Verifier kernels. Pose integration, observation
           update (Kalman), object logits, relation logits.
           Each affine after canonical projection.
  Part 5 — Multimodal composition with v7. Where v7 ends, v7-W
           begins; cumulative ε across substrates; frame-
           transform anchoring.
  Part 6 — Adversarial corners. Frame spoofing, time skew,
           observation injection, privacy.
  Appendix — Worked SLAM example with full ε budget.

Hard constraints honored: stays inside SQD A1-A3 (canonical
encoding, public quantization, collision-resistant hash); no new
axiom; every π*_w defined on quantized integer state, never on
continuous tensors.

2. docs/v7w-frontier-catalog.md (262 lines)
============================================

Operator-facing quick reference for the four ε-frontiers from
substrate-paper Part 4. Each entry:

  - canonical input / output bytes
  - operator (linear / bilinear / Kalman / SE(3))
  - ε bound expression
  - "affine after canonical projection" justification
  - when to use

Reference table + cumulative-ε section so operators sizing
deployment grid choices can read off their ε_total under typical
agent-trace + scene-graph workloads.

3. arborist/world/__init__.py — namespace reservation
======================================================

Reserved ``arborist.world`` package. No kernels yet. Module
exports V7W_VERSION ('v0-draft') + STATUS ('namespace_reserved')
metadata. Package docstring lays out the future shape per
substrate-paper Part 4:

  arborist/world/
  ├── pi_star/        — π*_w canonical projections (5 tuple classes)
  ├── frontier/       — ε-frontier kernels (4 frontiers)
  ├── frame.py        — frame definitions + transforms
  ├── clock.py        — wall-clock + Lamport
  ├── manifest.py     — substrate manifest schema
  └── adapters/       — sensor adapters land here, separate tickets

Implementation tickets cite the substrate paper and land kernels
one at a time; the stub exists so cross-referencing imports (mesh
peers, sibling repos) can pin the namespace before anything
implements it.

5 tests pin the reservation contract (test_world_namespace.py):
import succeeds, V7W_VERSION reports v0-draft, STATUS reads
namespace_reserved, __all__ exposes only metadata, substrate
paper + frontier catalog files exist alongside the namespace.

Closure criterion (#000013 §7): substrate paper lands and is
ready for review. Done. Status flipped to closed in the ticket
file + TICKETS.md index entry.

Test suite: 1641 passed, 37 skipped (was 1636; +5).

Raw Blame History

Arborist tickets — index

Arborist uses a flat ticket-NNNNNN-<slug>.md convention for actionable proposals: defects with a known root cause, design proposals awaiting go/no-go, or scoped enhancements queued for future implementation.

Convention

Filename: docs/tickets/ticket-NNNNNN-<slug>.md. The ID is a six-digit zero-padded integer; the slug is hyphen-lowercase and short enough to stay readable on a 100-column terminal.
Numbering: monotonic, never reused. Pick the next free integer greater than every existing ticket. The current next ID is on the Next ID line below; bump it when you open a ticket and commit the bump in the same commit as the new ticket file.

Header: every ticket starts with

# Ticket #NNNNNN — <short title>

**Status:** open · awaiting go/no-go      (or "in progress", "closed")
**Opened:** YYYY-MM-DD
**Scope:** <one-liner — what this ticket is for>
**Audience:** <who reads this>
**Hard constraint:** <invariants this ticket commits to NOT break>

Body: problem statement, design choices with trade-offs, recommendation, implementation sketch, scope boundaries, status. See ticket-000001-retrieval-keywords-audit-gap.md for a worked template.
Closure: when a ticket lands, flip Status to closed · landed in commit <sha> and leave the file in place. Do not delete tickets; they are the design log.

Distinction from other docs

docs/ also contains architecture references and bench journey notes that are NOT tickets — they describe state of the world rather than proposing change. Examples that stay un-numbered:

cti-architecture.md (architecture reference)
mesh.md, mesh-deploy.md (architecture + ops reference)
qa-modes-bench-2026-04-30.md (point-in-time bench journal)
verifier-semantic-gap-design.md, self-reference-design.md (older design docs that pre-date the ticket convention; leave as-is unless retroactively promoting one to a ticket adds value)
concept-relations-design.md (architecture reference for the per-shard concept_relations synonym/rivalry layer + the 1.6% storage-tax rationale; landed 2026-05-01)
tool-action-dag-design.md (research path for an action- provenance layer downstream of final_label. Captured pre-ticket per the 2026-05-07 arborist-vs-donto comparison; promotes to a ticket when an actual agent use case surfaces)

If a doc proposes change AND awaits a decision AND has scoped implementation cost, it's a ticket. Otherwise it's reference.
