+## Session Summary -- Product Owner Run 23 (2026-04-25, Lux)
+
+Embodiment: Lux -- TypeScript Engineer, prism symbol, "Implement, refine."
+
+## Scope
+
+Roadmap maintenance for `terraphim/agent-tasks`. Three feature issues created from a gap analysis between specs (`terraphim-agent-session-search-spec.md` v1.2.0, `learning-capture-specification-interview.md`) and the current open backlog.
+
+## Issues Created
+
+- **#38** -- `learnings`: TOML config loader for `.terraphim/learning-capture.toml`. Adds `LearningCaptureConfig::load`, `load_or_default`, project->global->defaults precedence, ignore-pattern merge, custom redaction patterns. ~250-350 LOC. Independent.
+- **#39** -- `terraphim_sessions`: first-class `CodeSnippet` model + `Message.snippets`. Wires NativeClaude, Aider, and Cline connectors to populate snippets from fenced markdown blocks. ~300-400 LOC. Blocks #5 (Tantivy `code_content` index).
+- **#40** -- `learnings`: auto-suggest correction from local KG thesaurus during capture. Adds `suggest_correction_from_kg`, `CorrectionType::AutoSuggested`, integrates into `capture_failed_command` between redaction and storage. ~200-300 LOC. Independent.
+
+Dependency edge: `gtr add-dep --owner terraphim --repo agent-tasks --issue 5 --blocks 39` (#5 blocked by #39).
+
+## What Worked
+
+- `--body-file` everywhere -- no KG-hook title mangling (Run 5/8 learning held).
+- Reading `mod.rs`, `redaction.rs`, `capture.rs` and the sessions `model.rs` before drafting the issue scope kept the acceptance criteria honest about what already exists vs. what needs writing.
+- Cross-checking the FieldMode/BudgetEngine code confirmed that #7 already covers Phase-1 CLI wiring; no duplicate issue created.
+
+## What Failed / Surprised
+
+- Initial Write to `/opt/ai-dark-factory/reports/roadmap-20260425.md` failed because it was already populated by Run 18 (same-day). Fixed by Read-then-Edit-append, preserving prior content.
+- `TodoWrite` arrived as deferred -- had to load schema via `ToolSearch select:TodoWrite` first.
+
+## Key Decisions
+
+- Three issues, not five: enforced `<=3` per run cap. Held back Phase-1 robot tail items (#11/#7/#36) since they are already issued; preserved review bandwidth.
+- Issue #39 is structured so #5 can rely on `Message.snippets[].content` once landed -- avoids a second migration when the Tantivy `code_content` field is added.
+- `#38` deliberately scoped without a CLI `--config` flag; that is a separate follow-up so the merge surface stays small.
+
+## Spec Coverage Updates
+
+- session-search: ~99% -> ~99.5% with #39 closing the F4.2 data-model gap.
+- learning-capture: ~85% pending #38 (config) and #40 (auto-suggest).
+
+## Top 5 Ready (PageRank)
+
+Recorded in `/opt/ai-dark-factory/reports/roadmap-20260425.md` Run 23 section.
+
+## Notes for Next Run
+
+- Verify the dispatch loop on closed `pull_request:null` mentions has not regressed -- merge-coordinator memory entries show ~50 no-op runs.
+- F4.4 `/sessions analyze` (#16) and F5.3 lesson injection (#668) still pending downstream of #14, worth re-checking once #14 lands.
