Session: fusion_similarity_run

Updated: 2026-03-23T16:47:04Z

Goal

Record outcomes and metrics from the completed fusion+similarity run so work can resume and a short QA can be executed.

Constraints

• Keep summary minimal and machine-readable where detailed counts live in the attached JSON.
• Do not expose secrets.

Progress

Done

• Fusion + similarity run completed and core results captured (totals recorded below).

In Progress

• Short QA: sample similarity lookups (recommended)

Blocked

• None blocking; QA recommended to validate results and sampling.

Key Decisions

• Pad vectors where necessary: Several windows had inconsistent vector dimensions; vectors were padded to a common dimension to allow fusion/similarity processing. Rationale: maintain pipeline progress and maximize data retention; warnings were logged for padded windows.

Next Steps

1. Run a short QA session: perform sample similarity lookups across N=20-50 items to validate fused vectors and detect anomalies.
2. Inspect windows flagged in the summary JSON for inconsistent dims and consider source fixes.
3. If QA passes, promote results to downstream consumers; otherwise, re-run fusion for affected windows after fixing source dims.

• Totals:

  • embeddings: 28172
  • fused_embeddings: 40524
  • similarity_rows: 405216

• Per-window inserted counts and any per-window errors are recorded in: thoughts/ledgers/fusion_similarity_summary.json (JSON summary attached to repo). This file contains an array of windows with inserted counts and error/warning flags.

• Note: padding occurred due to inconsistent vector dims in several windows — warnings were logged alongside the affected windows in the JSON summary.
