Build the funnelling-mechanism instrument for the RQ2-P3 follow-up: a new
`bridge-federated-pool` topology drawing each circuit's bridge from a finite
willing-bridge pool (size B) under Zipf willingness skew (alpha), so bridge
concentration genuinely varies as a manipulated IV. Defensive measurement only:
synthetic seeds, no engine, no traffic, no confirmatory record read.
- assembler.py: add `bridge-federated-pool` branch + zipf_weights/weighted_draw
helpers; existing lead `bridge-federated` branch left untouched and
bit-reproducible (fresh bridge per seed).
- battery.py: enumerate_rq2p3_cells() = B{2,4,8} x alpha{0,1,2} + anchor B=50,
alpha=0 (separate fn; frozen 6-cell lead lattice unmutated).
- analysis/rq2p3_calibration.py: DRY synthetic-only §7 calibration gate; no
confirmatory data read. confirm_load_rq2.py/confirm.py/stats.py unchanged.
- tests/test_sor_rq2p3_pool.py: 9 synthetic tests (helpers + pool reuse/variance
+ lead branch reproducibility).
Calibration gate RAN: items 3 (monotonicity) & 4 (entropy) PASS; items 1 & 2 do
NOT match their naive-funnel wording because the ratified posterior yields a MIX
(rho>0 across the whole sweep incl anchor rho=+0.838; B=1 -> H=2.54 bits HIGH) --
the note-unique-bridge-artifact.md prediction, surfaced early. HARD HOLD: no
confirmatory battery, no prereg freeze; NEEDS-OPERATOR banner raised for the §7
item-1/2 re-word decision. Lead prereg SHA f22331a72e... untouched; worktree-only.

Wire the live per-cell condition assembler (cmd_chat/sor/assembler.py): compose
the existing R1/R4/R5/R6 pieces into a condition-encoding CircuitSpec per frozen
§2 cell, so a cell_id maps to a genuinely distinct, ForwarderPlan-gated
(engine != local) isolated circuit rather than the plain 3-hop control:
- RQ1 bridge-on / on+padding insert a live bridge hop (+ R1 PADDING stream);
- RQ2 bridge-/directory-federated genuinely span >= 2 houses
(federation.select_federated_path, split-knowledge).
Plans only: opens no socket, moves no traffic, stands up no engine.
battery.assembler_dry_check validates on FIXTURES (6/6 cells distinct
fingerprints, all isolation-gated, same (cell,seed) reproduces, RQ1 bridge +
padding arms live, RQ2 federation >= 2 houses); write-once, kept out of any
confirmatory data dir. confirmatory_run preflight now runs it; the --operator-go
path no longer refuses cells as "not wired" — triple-lock + green preflight HOLD
on grid completion, then surface the operator's immutable data-run gate. No
confirmatory cell is ever fabricated.
Start-line instrument-validation gate (cmd_chat/sor/gate.py), grid + containment
pin (grid.py), and the guarded launcher (confirmatory_run.py) land alongside.
Holm: hold family_size = 7, report the 4 RQ1/RQ2 tests -> multipliers 7,6,5,4.
This is the pre-registration, not a deviation (prereg §6 [APPROVAL] size-7 family
+ D6 disclosure in the lead paper); docs/stage-05-holm-clarification.md marked
RATIFIED. RQ3-fold and alpha-split declined.
Containment intact; prereg untouched (SHA f22331a72e...); worktree-only. output/
gitignored (runtime artifacts, never source). Full SOR suite 156 passed. No
confirmatory data collected — the live data run remains the human gate.
