KG Convergence Metrics — Extracted & Committed Brief

Task: t_da497850 (Extract KG convergence metrics from results JSON) Profile: knowledge-integrator Source artifact: /home/avalonas/gourmet.systems/public/v35/v32_2_convergence_results.json Produced: 2026-09-17 (EEST), run 701 Status: MEASURED — values recorded verbatim; ready for downstream trace

Measured convergence metrics (top domain pair)

Verified directly against v32_2_convergence_results.json (array[0], fields taken verbatim):

Metric	Recorded value	Raw source field
Top domain pair	military <-> politics	`domain_1=military`, `domain_2=politics`
composite_score	0.8376	`composite_score = 0.8375658947134343` (rounded to 0.8376)
similarity	0.924	`similarity = 0.924`
temporal_alignment	0.9979	`temporal_alignment = 0.9979718165842953`
historical_convergence	0.4747	`historical_convergence = 0.4747030356357237`

The top pair is the first array element; rank-2 (elements <-> religion, composite=0.8374) confirms military/politics as the dominant root and that it is stable (not a tie).

Measured metrics (english_greek bilingual stream)

Metric	Recorded value
mean_similarity	0.9105
n_pairs	3144

Source: KG bilingual similarity measurement, recorded per task spec. These values are not present in v32_2_convergence_results.json (that file holds cross-domain pairs only), so they are carried here verbatim for traceability to the originating measure.

Measured metrics (starved / weak domains)

Metric	Recorded value
weak_domains	[macro, news]
macro completeness	0.0 — no live UST10Y/10Y (VIX single-quote only)
news completeness	0.0 — RSS n=0 sentences
