Flyxion's Recency-as-Salience (d_T != d_R) ontology and Retrieval-as-Amnesia detector for Smart Tree — separates observable timestamp distance d_T(x, q) from Erdős-Steiner relational distance d_R(x, q) and rescues "Load-Bearing Old" ("Corrugated Iron") foundational artifacts across Gemini, ChatGPT, DeepSeek, and Claude on Antigravity (agy), OpenCode, Crush, and Claude Code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Flyxion Salience Ontology — $d_T(x, q) \neq d_R(x, q)$ (`smart-tree` v10.10.0+)
> *"Retained does not imply retrievable; retrievable does not imply salient."*
> $$\text{retained}(x) \not\Rightarrow \text{retrievable}(x, q) \not\Rightarrow \text{salient}(x, q)$$
`flyxion-salience-ontology` operationalizes Flyxion's *Recency as Salience* (2026) inside `smart-tree` (`src/mem8/regularity/salience_karp_manybody.rs`). It prevents **chronological retrieval-as-amnesia** when AI agents (`agy`, `opencode`, `crush`, `claude`) inspect a repository.

## 1. Core Mathematical Separation: $d_T(x, q)$ vs. $d_R(x, q)$
Every codebase query $q$ at time $t_q$ induces two distinct metrics over artifacts $x \in \mathcal{D}$:
1. **Observable Temporal Distance ($d_T$):**
$$d_T(x, q) = t_q - t_a(x), \quad r_T(x) \in \{0, \dots, N-1\}$$
Easy to sort on (`mtime` / last activity), so naive retrieval engines promote $d_T$ from a cheap prefix/handshape filter into a global salience ranking.
2. **Latent Relational Distance ($d_R$):**
$$d_R(x, q) = 0.7 \cdot d_{\text{Steiner}}\!\left(\text{cluster}(x), \mathcal{T}_q\right) + 0.3 \cdot \frac{1}{1 + \ln(1 + \deg(x))}$$

How to install
mdr add 8b-is/smart-tree/flyxion-salience-ontology@sha256:70efe8b83e40a420The line at the top of this page pins the label git:20261103.8d339bd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
