The use of De Bruijn indices suggests support for lambda calculus or similar formal systems. +4. The code is designed to handle complex nested expressions efficiently. + +However, this implementation seems to focus more on the expression handling part of Deliverable 1. To get a complete picture of the graph database implementation, we might need to look at additional files that deal with: + +1. Triemap implementation for S-expressions +2.

Dyck Word Representation (lib.rs): + - Uses a 64-bit integer to represent Dyck words, allowing for efficient bitwise operations. + - Implements `DyckStructureZipperU64` for traversing and manipulating Dyck structures. + +2. S-expression Parsing (lib.rs): + - Implements `DyckParser` for parsing S-expressions into Dyck word representations. + - Supports variables, atoms, and nested expressions. + +3. Pattern Matching (lib.rs): + - Implements `match_template_at_current` for pattern matching on S-expressions. + - Supports variable binding and substitution. + +4. De Bruijn Indices (lib.rs): + - Uses De Bruijn indices for variable representation, allowing for efficient alpha-equivalence checking. + +5.

This benchmark provides valuable insights into the practical application and performance of the graph database implementation. Let's analyze the key components of this file: + +1. Data Structures: + - Uses `BytesTrieMap` for storing symbols and family relationships. + - Implements a custom `DataParser` for tokenization. + +2. Parsing and Loading: + - Reads data from a file (likely containing family relationships). + - Parses S-expressions using `ExprZipper` and loads them into the `BytesTrieMap`. + +3. Data Transformation: + - Implements a rule to transform "parent" relationships into "child" relationships. + - Uses zippers (`ExprZipper`) for efficient traversal and manipulation of expressions. + +4. Performance Benchmarking: + - Measures the time taken for parsing, loading, and transforming the data. + +5. Query-like Operations: + - Although not explicitly implementing queries, the code demonstrates traversal and manipulation of the data structure, which are fundamental to query operations. + +Key observations: + +1. The `BytesTrieMap` is used as the core data structure, which aligns with the triemap concept mentioned in Deliverable 1. +2. The implementation demonstrates efficient parsing and manipulation of large datasets (e.g., `royal92_simple.metta`). +3. The use of zippers (`ExprZipper`) for traversal and manipulation is consistent with the zipper-based approach seen in other parts of the project. +4. The benchmark shows how the system handles real-world data and transformations, which is crucial for assessing the performance goals of Deliverable 1. + +This file provides evidence of progress on several aspects of Deliverable 1: +- Expression queries (using BytesTrieMap) +- Efficient space-wide operations (demonstrated by the parent-to-child transformation) +- Scalability (handling large datasets) + +However, we're still missing explicit implementations of: +1.

If it succeeds, we promote the projection to real evidence; if it fails, the match is discarded. + +New predicates introduced +- pev (: p t) ob — projected evidence of t (with proof p) that depends on obligation ob. +- pevw (: p t ob) — a “work item” marking that the obligation ob for projected t is enqueued and must be proven before we can promote to ev. + +What each new rule does +- proj-and-r-kb / proj-and-l-kb: + - From a KB fact of the form (: k (And ob need)), extract the need and record the sibling ob as obligation. + - Emits pev (: p need) ob. + - l vs r just handles whether need is on the left or right side of And. +- proj-and-r-ev / proj-and-l-ev: + - Same as above, but source is already derived evidence ev instead of kb. +- pev-enqueue: + - Triggers only when a current goal wants the same (: p t) that a pev offers. + - It enqueues the obligation as a new goal: goal (: q ob), and records pevw (: p t ob) so we know to promote later. + - Key point: this happens under the current unifier, so any existential variables in ob are instantiated consistently with how t matched the goal. +- pev-promote: + - When the obligation ob is proven (ev (: q ob)), and the pevw marker is present, promote the projection to real evidence: ev (: p t). + +Why this matches the existential plan from existential.txt +- We never synthesize fresh witnesses. We leave the existential variable in the projected atom and unify it when a query demands it. +- The sibling conjunct becomes an obligation tied to that instantiation. If it can’t be proven, the projected match is never promoted to ev, so it naturally backtracks. + +Operational flow on a concrete shape +- Suppose you have a fact/rule producing And of two atoms, e.g. (And (Cat $c) (Chase $d $c)). +- A query wants (Chase blacky me). + 1. A proj-and-* rule matches the And and emits pev (: p (Chase $d $c)) (Cat $c). + 2. The goal unifies (Chase $d $c) with (Chase blacky me), binding $d=blacky, $c=me. + 3. pev-enqueue fires, adding goal (: q (Cat me)) and recording pevw (: p (Chase blacky me) (Cat me)). + 4. If (Cat me) is proven (from kb or derived), pev-promote yields ev (: p (Chase blacky me)). + 5. If (Cat me) can’t be proven, there’s no promotion; the match is discarded implicitly. + +Design notes and scope +- The four proj-and-* rules cover both kb and ev sources and both And orders. +- Obligations are first-class mm2 facts; nothing in Rust changes. They live in the same BytesTrieMap alongside other items. +- This setup handles two-way And as written. If you need to support n-ary And, either ensure And is binary/nested or add rules to decompose/solve And obligations. +- Obligations are lazy: created only when the projection is actually used by a goal, avoiding unnecessary work. + +In short: we encoded existential-friendly projection by introducing a projected-evidence lane (pev → pevw → ev) that enforces proving the sibling conjunct under the exact instantiation chosen by unification with the query. + +> Tokens: 8.0k sent, 2.7k received.
