+`.claude/plans/post-teardown-buildup-survey-v1.md`. First step after the
+semantic-family recovery (`E-SIX-SEMANTIC-FAMILIES-MUST-NOT-IMPERSONATE-EACH-OTHER-1`,
+#1134 / OGAR #298): the six families treated as ingredients, not competing
+owners of one lane. Four read-only traces over merged main produced a
+six-family inventory, a 35-row atom/operator inventory (files cited), an
+11×6 family×operator legality matrix (lawful / unsupported / aliasing), nine
+candidate molecules classified expressible / needs-operator / needs-missing-
+information, and seven missing-information gaps. Headline: family 3
+(population geometry) can be tried as a MOLECULE — every ingredient for a
+population-relative readout exists (Cam96 centroid distance, Fisher-z,
+`RollingFloor::occupancy`, `shuffle_beliefs_null`) and nothing is wired into
+any selection path; `select_tactic` reads four scalars with zero population or
+qualia input. Gates one experiment, PROBE-POP-READOUT-1 (D-POP-1): does the
+composed readout beat `curiosity` and `curiosity_gestalt` at predicting
+later-confirmed frontier edges on the KJV stream, above a size-preserving
+shuffle null. No code, no tenant, no ClassView, no opcode, no axis
+vocabulary; a PASS licenses a readout molecule only.

+## 2026-09-02 — lance-graph branch `claude/medcare-rs-continue-6nhbxn` (survey PR, opened after #1134) — post-teardown buildup survey v1
+
+- **Added:** `.claude/plans/post-teardown-buildup-survey-v1.md` (survey,
+  plan-only); `INTEGRATION_PLANS` entry; `STATUS_BOARD` section with
+  D-POP-0/1/2; this entry.
+- **Locked:** nothing new — the six-family ruling stands; the survey records
+  which compositions are lawful, unsupported or aliasing under it.
+- **Deferred:** every carrier decision for population geometry until
+  PROBE-POP-READOUT-1 (D-POP-1) reports; the EMPTY nibble; philosophical
+  names as storage.
+- **Confidence:** High for the inventories (file-cited, four independent
+  traces); Medium for the legality matrix (a reading of the ruling, not a
+  test); the experiment is pre-registered, unrun.
