Record

Three longer notes. Each stays compact and sticks to what was measured on disk. The full list is the ledger.

Buffer Limits

Eaten at the Letter G

Chapter 4 shipped with a clean bibliography, but twenty-six of its thirty-six references were missing. The export buffer hit a ceiling and sliced the catalog alphabetically at the letter G while reporting a clean exit.

This note follows an export that looked clean. The catalog ended at the letter G, and the shortfall stayed hidden behind a clean exit. Counting before and after is the only move that catches this class.

Law: Unchecked truncation presents identically to clean completion.

Instead: Enforce explicit pre- and post-generation item counts on every output collection.

Bibliographic Verification

The Hundred-Percent Failure Run

A literature sweep ran end to end without an active verification checkpoint. Every generated citation failed inspection, with nonexistent authors, misattributed dates, and fabricated articles wrapped in fluent prose.

This note follows a sweep with no checkpoint. Every citation failed, yet the prose stayed fluent. A validator outside the generator is the gate that stops drift from shipping.

Law: Unverified citation generation yields complete bibliographic drift.

Instead: Gate every literature pass through an external citation validator.

Test Suite Blindspots

Green Tests on an Omitted Voltage

The test harness ran 143 unit tests and 26 invariants to green status. The core binding energy calculation held a critical physics defect, as it omitted the applied sample bias entirely from the equation.

This note follows a green suite. Tests passed while the core equation left out applied bias. Ground truth and outside review are the checks that find what the suite never asked.

Law: A green test suite only proves you tested what you remembered to question.

Instead: Benchmark physical equations against known analytical ground truth and outside review.
