LAV v1.5 builds on v1.4 by incorporating five structural findings (STF-001 through STF-005) surfaced when LAV v1.4 was stress-tested against a real audit of the FCL Master v2.6 document. The findings revealed gaps in v1.4's handling of: threshold boundary cases, compound terms built from DEFINED-status constituents, metric-field formula requirements, professional title vocabulary, and cross-document definition coherence. All five gaps are closed in this version.
| VERSION | CORE ADDITION | SOURCE |
|---|---|---|
| v1.0 | Five-stage core process. LDS formula. Three issuance categories. Self-audit revealing formula error. | Initial build |
| v1.1 | Formula corrected. Core terms audited. "Framework" → "Vector." "Audit" → "Root Listening." | Self-application |
| v1.2 | Protocol A: Compound Term. Protocol B: Cross-Language. Protocol C: Unrecoverable Root. RETIRED category added. | Expansion |
| v1.3 | Protocol D: Neologism Coining. Protocol E: Non-IE. Protocol F: Discourse-Level Drift. Drift Archive formalized. | Expansion |
| v1.4 | Protocol G: Temporal Drift. Protocol H: Cross-Framework Interference. Active Red Team System (five layers). | Expansion |
| v1.5 | STF-001 through STF-005. Boundary Tiebreaker. DEFINED×DEFINED detection. Protocol I. Protocol J. Step H6. | Stress-test FCL v2.6 |
Full Non-IE Auditing Capability — Protocol E provides principled engagement with non-IE language families but does not claim full auditing precision. Specialist collaboration is ongoing.
Predictive Drift Modeling — Protocol G measures velocity but does not forecast LDS trajectories. A predictive model is a future boundary.
Automated Ecosystem Mapping — Protocol H Step H1 requires manual ecosystem mapping. Automated detection is a future capability.
Red Team Performance Metrics — the Active Red Team System has no self-measurement. Tracking RT accuracy (true flags vs false positives vs missed drift) is the most significant gap remaining in v1.5.
Protocol I Historical Retroactivity — Protocol I resolves the formula gap going forward. Prior FCL entries using DEFINED-status metric fields without registered formulas carry PROVISIONAL status until retroactive registration.

| LDS SCORE | STATUS | REQUIRED ACTION |
|---|---|---|
| ≤ 0.399 | CONFIRMED | Root-defensible. Cleared for deployment. Document root encoding. |
| 0.400–0.599 | DEFINED | Mandatory operational definition specifying operative root dimension, excluded dimensions, conditions for revision. |
| 0.600–0.799 | CORRECTED | Root-restored replacement required. Retire original. Archive drift record. |
| ≥ 0.800 | RETIRED | Active conceptual damage. Remove from operational vocabulary. Replacement mandatory via Protocol D. |
| v1.5 Boundary Rule: LDS exactly at a threshold boundary → assigned to the more cautious (higher) category. | ||
| TYPE | DEFINITION | DETECTION SIGNAL |
|---|---|---|
| Narrowing | Root encoded broader reality; scope was restricted | Older texts use the term in contexts where current usage would substitute a different term |
| Expansion | Root encoded specific reality; scope extended beyond what root can support | Current usage covers more ground than the root's encoding allows |
| Inversion | Current usage implies something the root directly contradicts. Most dangerous. | Literal reading of root would produce opposite meaning to current usage |
| Pejorative Shift | Root was neutral; current usage carries negative valence | Value-laden connotation absent from root or early usage |
| Ameliorative Shift | Root encoded something charged; current usage has softened it | Comparison reveals lost intensity or difficulty in current usage |
| Reification | Root encoded a process; current usage treats it as a property. Most common in AI vocabulary. | Can the term precede "is absent" or "is present"? If yes, may be reified. |
| Colonization | Root appropriated by a discipline, narrowed to serve its needs | Usage outside the colonizing discipline feels "wrong" to specialists |
