+## 2026-09-02 — E-THE-CALIBRATION-GATE-REVERSED-THE-DECLARED-FLOOR-1 — D-TEH-2: the ghost prior landed in the planner, and the pre-registered gate overruled the floor its author had declared
+
+**Status:** FINDING (measured, `crates/lance-graph-planner/src/nars/ghost_prior.rs`, test `calibration_gate_picks_the_default_floor`). **Confidence:** High on the fixture; the fixture is one recurrence shape (256 atoms, a 3-atom pattern, 0–30 stale patterns, ages 0–60).
+
+**What landed.** `thinking_engine::ghosts::GhostField` is harvested as planner `nars::ghost_prior::GhostPrior` — per-thought / per-mailbox, never a singleton — over the contract's `WisdomMarker` / `GhostEcho`. `ghosts.rs` and its only consumer, `examples/think.rs`, are deleted; the lab crate's `persona` / `world_model` / `awareness_dto` now import `GhostEcho` from the contract, which closes `TD-GHOST-ECHO-DUP-1` (one declaration of the eight echoes remains). The lab `Agent` no longer OWNS a trace field; DTO builders take the thought's prior summary as an argument — the V3 ownership rule applied to a process-wide field.
+
+**The finding.** The closure plan's §1c row said the port must declare which floor it adopts — the source's (drop below 0.001, prune) or the contract's (clamp at 0.1 forever) — and let a calibration gate decide: free-energy discrimination between a RECURRENCE and a SHIFT after the prior has aged. The first declaration was the source's `Trace` floor. The gate rejected it. Discrimination (`fe_shift − fe_recurrence`), Trace vs Marker: with no stale memory the two are identical (0.0188); with 30 stale patterns and age 0, 0.0002 vs 0.0026; with 30 stale patterns and age 20 or 60, **0.0000 vs 0.0188**. Under the Trace floor the remembered pattern is pruned once older than ~42 cycles (`0.8·0.85ᵏ < 0.001`) and the prior can no longer tell familiar from new at all. Under the Marker floor it survives at 0.1 and the discrimination holds — at the price of a noisier baseline (absolute free energy 0.35 vs 0.07 with 30 stale patterns). The anchoring alarm (D-HOUSE-4) reads the difference, not the level, so the default is `Marker`: the contract's `felt_parse:70` semantics ("never fully vanishes"), now measured rather than inherited.
+
+**Why it is worth an entry.** The author of the port had a preference (the bias-semantics floor) and wrote the gate before running it; the gate's assertion is on the DECLARED default, so the preference could not survive the fixture without the test going red. That is the falsifiability rule doing what it exists for — a knob that is set by a measurement it can lose, not by the name of whoever set it. The shape generalises: when two shipped sources disagree on a constant, encode the disagreement as a parameter and let a pre-registered fixture pick, with the assertion on the pick.
+
+**Fences carried forward.** Lingering trace ≠ counterfactual rung (`E-A-GHOST-TRACE-IS-NOT-THE-COUNTERFACTUAL-LANE-1`): nothing in `ghost_prior` reads or writes the −6 lane. The floor decision is scoped to this fixture; D-HOUSE-4 should re-run `calibration::discrimination` on its own recurrence shape before trusting the default there.
+
+Refs: `thinking-engine-harvest-closure-v1` §1c (ghost row), §3 W2 result, §5 D-TEH-2; `house-differential-style-v1` D-HOUSE-4; `contract::escalation::{GhostEcho, WisdomMarker}`; `TD-GHOST-ECHO-DUP-1` (resolved); `TD-GHOST-TIER-NAME-COLLISION-1` (still open, pays when `counterfactual.rs` is next touched).

+## 2026-09-02 — branch (D-TEH-2, after #1141 merged): ghost prior harvested into the planner — INVENTORY DELTA
+
+- MERGED #1141 (D-HOUSE-1, `3102776`): no contract type; planner example `house_differential.rs` + plan/board records (see PR_ARC).
+- ADDED planner `lance_graph_planner::nars::ghost_prior` — `GhostPrior` (per-thought Friston prior over atoms: `imprint` / `bias` / `prediction` / `free_energy` / `active_count` / `prune` / `summary` / `tick` / `echo_for`), `PriorFloor { Marker, Trace }` with `DEFAULT = Marker` (decided by the calibration gate, see EPIPHANIES `E-THE-CALIBRATION-GATE-REVERSED-THE-DECLARED-FLOOR-1`), `Trace` (atom + `WisdomMarker` + birth cycle), `calibration::{recurrence_fixture, discrimination}` (library code so a consumer can re-run the gate on its own fixture). Re-exported as `nars::{GhostPrior, PriorFloor}`. 15 tests (incl. the Codex-review pair: summary per-atom-max-before-sort, fixture refuses an atom space below `calibration::FIXTURE_MIN_ATOMS` = 63 — `recurrence_fixture` / `discrimination` return `Option`; and the CodeRabbit boundary: `calibration::FIXTURE_MAX_STALE_PATTERNS` = 21_812 refuses a stale-pattern count whose atom id would wrap `u16`). Consumes contract `escalation::{GhostEcho, WisdomMarker}` only; no new dependency, no new contract type, no tenant, no layout change.
+- REMOVED (lab crate, excluded from the workspace) `thinking_engine::ghosts` (`GhostType`, `Ghost`, `GhostField`) and `examples/think.rs` (its only consumer). `persona::Agent` lost its `ghosts` field; `Agent::to_dto(ghost_count)`, `Agent::self_model(.., ghost_count, dominant_ghost)` and `WorldModelDto::build(.., trace_count, dominant_trace)` take the thought's prior summary as arguments; the `A2AMessage::{thought, knowledge, persona_exchange}` constructors take the sender's `AgentDto` snapshot (built by the caller via `to_dto(ghost_count)`) instead of hardcoding a zero count; `SelfModelDto::dominant_ghost_type`, `GestaltState::dominant_trace`, `QualiaDto::traces` are typed over `contract::escalation::GhostEcho`. Lab crate: `cargo check --lib --examples` clean (pre-existing warnings only), persona/world_model/awareness_dto tests 14/14.
+- RESOLVED `TD-GHOST-ECHO-DUP-1` (one declaration of the eight echoes remains — the contract's).
+- UNCHANGED: `contract::escalation` shapes (`GhostEcho`, `WisdomMarker::{FLOOR, DECAY, intensity_at}`) — only a doc comment; the ALU artery files (`dto.rs`, `engine_bridge.rs`, `cognitive_shader.rs`, `mailbox_soa.rs`) untouched.
+
 ## 2026-09-02 — branch (D-TEH-1, first code wave after #1138): `bridge_gate` moved to the contract — CONTRACT INVENTORY DELTA
 
 - ADDED `lance_graph_contract::bridge_gate` — the cross-tenant authorization injection point, moved from `thinking_engine::bridge_gate` with all seven public items together and identical shapes: `CognitiveOpKind` (4 variants, `repr(u8)`), `CognitiveAuthResult { Allow, Deny, Escalate }` + `is_allowed/is_denied`, `CognitiveBridgeError { Denied, Escalation }`, `auth_to_result`, the `CognitiveBridgeGate: Send + Sync` trait (3 sync methods), `PassthroughGate`, `DenyAllGate`. Zero-dep (std only). Its 9 unit tests moved with it; the engine-side `pure_ops_dont_touch_gate` stays in thinking-engine next to the lens modules it calls.

+
+- **Added:** `crates/lance-graph-planner/src/nars/ghost_prior.rs` — `GhostPrior`, `PriorFloor`, `Trace`, `calibration::{recurrence_fixture, discrimination}` (both `Option` below `FIXTURE_MIN_ATOMS` and above `FIXTURE_MAX_STALE_PATTERNS`), 15 tests (monotone decay to each floor with the inert cycle derived from the constant, decay-constant load-bearing both ways, two-sided free energy under both floors, the calibration gate on the declared default, anti-vacuity that the floors differ, prediction shape, imprint cap, echo rule, independence of two priors); `pub mod ghost_prior` + re-export in `nars/mod.rs`. EPIPHANIES `E-THE-CALIBRATION-GATE-REVERSED-THE-DECLARED-FLOOR-1`.
+- **Removed:** `crates/thinking-engine/src/ghosts.rs`, `crates/thinking-engine/examples/think.rs`; `pub mod ghosts` from the lab `lib.rs`.
+- **Changed (lab crate):** `persona.rs` (`Agent` without a trace field; `to_dto` / `self_model` take the prior summary; `A2AMessage` constructors take the sender's `AgentDto`; `SelfModelDto` over `GhostEcho`), `world_model.rs` (`build` takes `trace_count` + `dominant_trace`; `GhostEcho`), `awareness_dto.rs` (`GhostEcho`), `domino.rs` (doc). Contract `escalation.rs`: `GhostEcho` doc comment (retired-mirror note). TECH_DEBT `TD-GHOST-ECHO-DUP-1` → RESOLVED. Plan §5 D-TEH-2 → Shipped, §3 W2 result; STATUS_BOARD D-TEH-2 Shipped, D-HOUSE-4 unblocked.
+- **Measured:** calibration gate rejected the first-declared `Trace` floor — discrimination 0.0000 vs `Marker` 0.0188 at 30 stale patterns / age 20 and 60 (equal at 0.0188 with no stale memory); absolute baseline 0.35 vs 0.07. Default = `Marker`. Planner clippy `-D warnings` + fmt clean; lab `cargo check --lib --examples` clean; lab tests 14/14.
+- **Locked:** per-thought ownership (no singleton field); the lingering-trace / counterfactual-lane fence; the floor as a measured parameter, not an inherited constant.
+- **Deferred:** D-HOUSE-4 (unblocked, not started — should re-run `calibration::discrimination` on its own fixture); D-TEH-3 (math → jc), D-TEH-4/5; `TD-GHOST-TIER-NAME-COLLISION-1` waits for the next touch of `counterfactual.rs`.
+- **Confidence:** High.

 - **Description:** `lance_graph_contract::escalation::GhostEcho` (8 variants: Affinity / Epiphany / Somatic / Staunen / Wisdom / Thought / Grief / Boundary) is a second declaration of the same 8 named ghost echoes already in `thinking_engine::ghosts::GhostType` (`crates/thinking-engine/src/ghosts.rs`). The duplication is *intentional and currently unavoidable*: `lance-graph-contract` is ZERO-DEP and cannot import the excluded `thinking-engine` crate, and the contract is the canonical "single source of truth for types" home for the wisdom-marker substrate (≤32 named identities per I-VSA-IDENTITIES). The two are NOT interchanged across a boundary today, so there is no silent-corruption risk (cf. I-LEGACY-API-FEATURE-GATED), only a naming/maintenance dup.
 - **Resolution (when thinking-engine joins the workspace):** make `thinking_engine::ghosts::GhostType` a re-export of (or `From`/`Into` with) `contract::escalation::GhostEcho`, retiring the thinking-engine copy. Until then, keep the variant sets identical (same 8, same order) so a future `transmute`/`From` bridge is trivial.
