Concept-spine alias-cluster detection report

Context

This is the close-target child for the detection/reporting half of #14502. The parent #14502 deliberately spans two phases: a safe full-spine alias-cluster detection report that can land now, and a canonical merge executor/tombstone path that must wait for #14474's probe artifact. A PR that only delivers the detector must not claim Resolves #14502, so this child keeps the close target honest while leaving #14502 open for the merge half.

Live latest-open sweep: checked the latest 20 open issues at 2026-07-02T21:33Z; no equivalent detection-only child exists. The sweep found parent #14502 and sibling #14503-#14508 GP-v2 leaves, but none cover the committed alias-cluster report surface. A2A in-flight sweep: checked latest 30 messages at 2026-07-02T21:33Z; only overlapping claim was @neo-gpt's own #14502 detection-slice claim.

The Problem

#14502's detection pass is independently useful before any merge executor lands. The live graph already contains concept-spine fragmentation: Golden Path aliases appear across CONCEPT:*, CLASS:*, and bare kebab ids; Dream Pipeline aliases span CLASS:DreamPipeline, CONCEPT:DreamPipeline, dream-pipeline, and related REM/Sandman bridges. Without a committed detector/report, later merge work risks acting from stale anecdotes instead of a reproducible full-spine measurement.

The Architectural Reality

• ai/services/graph/SemanticGraphExtractor.mjs returns raw CONCEPT: / CLASS: ids from message extraction; it does not canonicalize concept ids.
• ai/services/memory-core/MailboxService.mjs projects curated taggedConcepts directly as TAGGED_CONCEPT edges.
• ai/services/memory-core/GraphService.mjs protects only selected edge types from decay; concept edges stay under ADR-0024 decay semantics.
• ai/scripts/maintenance/ already owns one-shot/read-only audits such as auditGraphIntegrity.mjs; npm run --silent ai:structure-map -- --files --loc confirms this maintenance-script sibling pattern.

The Fix

Add a read-only maintenance audit that scans live SQLite graph Nodes/Edges, normalizes semantic node ids/names/aliases into kebab-case detection keys, unions per-node keys into alias clusters, computes neighborhood overlap/disjointness, and writes a markdown measurement artifact under learn/agentos/measurements/.

Contract Ledger Matrix

Decision Record impact

aligned-with ADR 0024. This ticket performs detection only and does not add protected edge classes, mutate weights, or choose canonical merge semantics.

Acceptance Criteria

• Read-only alias-cluster audit added under ai/scripts/maintenance/ with exported pure report functions and no live-store write path.
• Unit coverage proves id/name/alias bridging, known-probe markdown rendering, and neighborhood disjointness accounting.
• First full-spine measurement artifact committed under learn/agentos/measurements/, including Golden Path and Dream Pipeline known clusters.
• PR resolves this child only and references #14502 / #14472, leaving merge executor work open.

Out of Scope

• Canonical-id policy selection.
• Edge rewrites, alias tombstones, alias-map writes, or MAX-weight merge behavior.
• Mint-time canonicalization in SemanticGraphExtractor or MailboxService.
• Post-#14474 re-run of the read probe.

Avoided Traps

• Do not close #14502 from a detection-only PR.
• Do not SUM-merge weights or mutate decay semantics.
• Do not hard-delete aliases.
• Do not block concept mint/write paths on canonicalization.
