Early changelog

Aegis-Terminal — Changelog

Append-only. New entries at the bottom.

2026-09-13 — major infrastructure day

Pipeline architecture

• Added definition_path.py — classifier, seed, terminal resolution, formatter helpers
• Added disambiguation_route.py — ambiguity gate as a named function
• Added disambiguate.py — pure logic for ambiguity detection
• Added session_store.py — in-memory TTL session for sense memory

Definition fast path

• Wiktionary seed via Wikipedia REST summary endpoint
• Formatter v3 → v4 → v5 → v5b (appositive guard, list-reject, no double-copula)
• Terminal sense resolution: user pick returns exact doc, no pipeline
• Multi-token subject terminal (Apple Inc, Marie Curie)
• Single-token non-whitelisted terminal (Napoleon)

Classifier v2 / v2b

• Question words: what, who, where, when, define, explain
• Multi-token subjects up to 5 words
• Appositive-style extract handling

Ambiguity overlay

• Whitelist-gated detection (20 subjects)
• Frontend overlay with clickable sense cards
• Session memory so user teaches once per subject

User corrections

• query_corrections.py — save/get/forget
• Correction check runs first in query() — always wins
• Frontend widget: Helpful / Wrong / Teach Aegis buttons
• /query/correct and /query/feedback endpoints
• Used-count tracking on each correction

Observability

• query_log.py — every query logged with qtype, source, elapsed, feedback
• /debug/query_log and /debug/corrections endpoints
• NaN sanitizer for JSON-safe responses

Fast paths

• Math (arithmetic, roots, powers)
• Units (time, length, mass)
• Stock (Yahoo Finance via yfinance)
• Tutorials (manual for Python/Rust/JS/Go/SQL, structural for W3Schools topics)

Dead code cleanup

• Removed vector search chunks block
• Removed _low_no_art orphan
• Removed _wk_term orphan
• Removed verifier if-False gate
