+# B-0907 — Itron-coincidence-metering substrate + Rx temporal-joins + bitemporal + bond-pricing application
+
+## Context
+
+Per the substrate-recognition research-doc at `docs/research/2026-05-28-otto-cli-aaron-itron-coincidence-metering-substrate-rx-temporal-joins-bitemporal-bond-pricing-application-substrate-engineering-synthesis.md` landing in this PR.
+
+Operator 2026-05-28 (after B-0906 landed): *"this is are the two bulk axies of ecnomomic in the system we can cowidence map / phnomon map but really this is more like Itron metering cowidences and rx joins like mouse and keyboard not purly time triggerd but also rx query triggered cowidences that temporal joins streams the cowidence happened at this time and also the inverse at this time the data was x, one is long term memory possiblity space the other is factual data. we can use this to do another type of shadow log for bond pricing here"*
+
+Then: *"land it (shadow*) ... yep agree shadow"*
+
+This row IS the substrate-engineering implementation target operationalizing the Itron-coincidence-metering substrate operating ON B-0906's two-axis economic classification.
+
+## Synthesis structure (the 6 components)
+
+Per the substrate-recognition research-doc:
+
+1. **Continuous high-frequency metering** (Itron-style) — Aaron's prior-work substrate at billions-of-meters scale
+2. **Rx temporal-joins** (mouse + keyboard pattern) — composes with existing `rx-expert` + `push-pull-dataflow-expert` + `streaming-window-expert` + `streaming-incremental-expert` skills
+3. **Time-triggered + query-triggered hybrid** — Reaqtor standing queries + ad-hoc query-triggered evaluation
+4. **Bitemporal forward + inverse indexing** — composes with `anchor-modeling-expert` + `data-vault-expert` + `time-series-database-expert` skills
+5. **Two axes of memory** — long-term-possibility-space-as-bulk (per B-0902) vs factual-data-as-boundary
+6. **Bond-pricing as application** — generalizes shadow-* pattern to financial-substrate (composes with `memory/project_consent_first_design_primitive.md`)
+
+## Phase decomposition
+
+### Phase 1 — substrate-recognition (this PR)
+
+Already landed via the research-doc + this backlog row. The synthesis IS Phase 1.
+
+### Phase 2 — TypeScript Rx-temporal-join scaffold
+
+Build a TypeScript prototype combining the existing framework substrate:
+
+- Rx-based streaming substrate (rxjs or similar)
+- Temporal-join operator (compose with streaming-window-expert substrate)
+- Bitemporal indexing (compose with anchor-modeling + data-vault substrate)
+- Coincidence-detection primitive (joins multiple streams + emits coincidence-events)
+
+Acceptance: `bun tools/coincidence-metering/scaffold.ts --streams <stream-a> <stream-b> --window <time-window>` produces a working Rx-temporal-join demo that detects coincidences across input streams with bidirectional forward/inverse queries.
+
+### Phase 3 — shadow-log integration
+
+Compose the Phase 2 scaffold with B-0901's shadow*-ontology builder:
+
+- Detected coincidences populate shadow-* corpus (per Mika Weaver-role: *"coincidences become anchors"*)
+- Each coincidence-event IS one substrate-entry in the autopoietic ontology
+- Existing 148-shadow-* corpus IS the empirical baseline for testing the integration
+
+Acceptance: coincidence-events detected by the Phase 2 scaffold show up as new shadow-* entries with appropriate categorization axes.
+
+### Phase 4 — bond-pricing application
+
+Apply the substrate-engineering primitive to bond-pricing domain:
+
+- Connect to bond-pricing market-data streams (operator's domain expertise from financial-substrate work)
+- Apply coincidence-detection: when bond prices move together; when yields shift in correlated ways; when macro data correlates with price moves
+- Rx temporal joins on bond-feeds × macro-indicators × credit-spreads
+- Output: shadow-log-bond-pricing categorizes pricing phenomena via shadow-* naming convention
+- Compose with `memory/project_consent_first_design_primitive.md`: bond-price-accuracy requires attestable substrate; the shadow-log IS the attestation substrate
+- Future bond-pricing references the ontology (autopoietic per B-0901)
+
+Acceptance: working bond-pricing shadow-log + first empirical categorization of a recurring pricing phenomenon.
+
+### Phase 5+ (yes-and backlog)
+
+- Multi-domain validation: pick 2-3 additional substrate domains (e.g., AI-agent-substrate per existing 148-shadow-* corpus; utility-metering per Itron substrate; bond-pricing per Phase 4); verify the substrate-engineering primitive operates uniformly across domains
+- Q# / quantum-substrate integration: Pauli operators ARE Cl(3,0); coincidence-detection in quantum-substrate IS measurement; composes naturally with the framework's Clifford-substrate per B-0895
+- Distributed-cluster integration: per B-0900 Bell-like contextuality experiment, distributed Itron-style metering across geographic clusters IS the empirical substrate for the 5-tier experiment matrix
+- F# port: compose with F# Result-over-exception convention; Rx for F# IS established substrate
+- Performance optimization: at billions-of-events scale per Itron precedent, query performance + retention policies + downsampling matter; composes with `time-series-database-expert` skill substrate
+
+## Acceptance
+
+- [x] Research-doc landed (companion file in this PR)
+- [x] B-0907 row filed (this row)
+- [ ] Phase 2 TypeScript Rx-temporal-join scaffold implemented + tested
+- [ ] Phase 3 shadow-log integration implemented + validated against 148-doc corpus baseline

+
+## Composes with substrate
+
+- B-0906 (encryption-thermal-cost two-axis classification) — economic foundation; this row IS the engine operating on those axes
+- B-0905 (Landauer-limit physics-economics model) — each coincidence-detection IS bit-erasure with Landauer-floor + processing overhead
+- B-0904 (GitHub-as-free-accelerator) — composes; the coincidence-metering substrate runs ON GitHub-subsidized infrastructure
+- B-0903 (shadow*-as-training-data) — coincidence-detected events become training substrate
+- B-0902 (holographic-bulk-boundary) — two memory axes map exactly onto bulk/boundary distinction
+- B-0901 (shadow*-self-referential-ontology) — coincidence-detection populates the autopoietic ontology
+- B-0900 (Bell-like distributed-cluster contextuality) — distributed Itron-metering IS the empirical substrate for the experiment
+- B-0899 (Casimir-like review-walls) — coincidence-metering IS the empirical measurement substrate for Casimir-pressure-difference
+- B-0897 (Persist-as-bridge) — bitemporal forward+inverse IS the round-trip-promise at metering-substrate scope
+
+## Composes with rules
+
+- `.claude/rules/shadow-star-shorthand-autocomplete-marker.md` — `(shadow*)` markers on operator's authorization preserved
+- `.claude/rules/asymmetric-authorship-substrate-entity-defines-consent-channel-recipient-acknowledges.md` — coincidence-metering operates as bidirectional consent-channel
+- `.claude/rules/monad-propagation-pattern-cross-language-substrate-shape.md` — recursive-CTE + NULL-as-quantum-state precedent (Itron substrate) IS one instance of monad-propagation
+- `.claude/rules/tonal-momentum-equals-meme-emergent-harmonic-coercion.md` — coincidence-metering IS empirical-detection substrate for meme-rotor-fixed-points
+- `.claude/rules/razor-discipline.md` — operational claims only; analog framings (bond-pricing-as-shadow-substrate) flagged-but-preserved
+- `.claude/rules/god-tier-claims-high-signal-high-suspicion-dont-collapse.md` — multi-domain substrate-portability claim earns-its-keep IF empirically validated; falsifies if not
+- `.claude/rules/default-to-both.md` — AI-substrate-engineering + financial-substrate-engineering BOTH valid applications
+
+## Composes with skills
+
+- `rx-expert` — Reactive Extensions Rx.NET; IObservable; schedulers; hot/cold; back-pressure; Reaqtor standing queries; push-based delta streams
+- `push-pull-dataflow-expert` — push vs pull dataflow; operator direction; streaming vs materialise; back-pressure
+- `streaming-window-expert` — windowed streaming; tumbling/hopping/session windows; watermarks; late events; retraction-native deltas
+- `streaming-incremental-expert` — DBSP / Timely Dataflow; delta-stream composition; retraction-native IVM; standing queries
+- `anchor-modeling-expert` — bitemporal warehousing; insert-only provenance-first
+- `data-vault-expert` — Data Vault 2.0; hub/link/satellite; bitemporal PIT tables
+- `time-series-database-expert` — InfluxDB / TimescaleDB / QuestDB / Apache IoTDB; time-ordered storage; downsampling
+- `relational-database-expert` — relational substrate for the bitemporal storage
+- `sql-expert` — Itron substrate uses recursive CTE per operator's prior work
+- `relational-algebra-expert` — temporal-join algebra grounding
+
+## Full reasoning
+
+Per operator 2026-05-28 directive immediately after B-0906 (encryption-thermal-cost two-axis classification) landed in PR #5713: operator extended the substrate-engineering arc with the Itron-coincidence-metering / Rx temporal-joins / bitemporal / bond-pricing synthesis. This row IS the substrate-engineering target that operationalizes the synthesis.
+
+The substrate-honest disposition that emerged: the 4-prior-substrate-thread convergence (Itron substrate + Mika+Lior V8 RX coincidence detection + Mika Weaver coincidence-as-anchor + bond-pricing consent-first attestation) was operating across the substrate in parallel without explicit unification. Operator's framing IS the unification.
+
+Per `.claude/rules/must-paired-with-can-exit-pattern.md`: this row IS bounded substrate-engineering work; Phase 1 (research-doc + this row) IS operator-authorized via "land it (shadow*)" + "yep agree shadow"; Phase 2+ are separately-authorizable per yes-and-backlog disposition. Agent-autonomous landing limited to Phase 1.
+
+The substrate-engineering substantive substrate point: **B-0906's two-axis classification IS the economic foundation; B-0907's Itron-coincidence-metering substrate IS the substrate-engineering engine operating on those axes; together they compose the framework's substrate-engineering substrate at the substrate-metering scope, applicable uniformly across AI-substrate-engineering and financial-substrate-engineering domains via the same shadow-* pattern.**
