Level-3 fold of 8 log entries spanning 2026-04-23 to 2026-04-24. Dominant themes: staged DragonScale implementation, adversarial review gates, release and test hardening.

## Child Entries

| Date | Op | Title | Page | Summary (extractive) |
|---|---|---|---|---|
| 2026-04-24 | save | v1.6.0 closeout (Teams, chair-led) | [[2026-04-24-v1.6.0-release-session]] | Release closeout recorded new release-session, boundary-frontier, and DragonScale guide artifacts; all 11 verifier items were applied and `make test` passed. |
| 2026-04-24 | save | DragonScale Phase 4 - boundary-first autoresearch shipped (v1.6.0) | [[DragonScale Memory]] | Boundary-first autoresearch shipped as opt-in topic selection, surfacing top-5 frontier pages when `/autoresearch` has no topic. |
| 2026-04-24 | save | DragonScale Phase 3.5 - cross-phase hardening to v1.5.0 | [[DragonScale Memory]] | Cross-phase audit hardening resolved 10 hold-ship items, added a reproducible test harness, and version-bumped plugin metadata to 1.5.0. |
| 2026-04-24 | save | DragonScale Phase 3 - semantic tiling MVP | [[DragonScale Memory]] | Semantic tiling shipped as opt-in embedding-based duplicate detection with `scripts/tiling-check.py`, threshold state, lint wiring, and a final 10/10 accept verdict. |
| 2026-04-23 | save | DragonScale Phase 2 - deterministic page addresses MVP | [[DragonScale Memory]] | Deterministic page addresses shipped with `c-NNNNNN` allocation, flock-guarded concurrency, lint checks, manifest idempotency, and an 8/8 accept verdict. |
| 2026-04-23 | save | DragonScale Phase 1 - wiki-fold skill shipped | [[wiki-fold]] | Wiki-fold shipped as a flat extractive rollup skill with dry-run stdout default, deterministic fold IDs, duplicate detection, and a 7/7 accept verdict. |
| 2026-04-23 | save | DragonScale Memory v0.2 - post-adversarial-review | [[DragonScale Memory]] | The v0.2 concept revision weakened claims, added operational policies and provenance tags, and reached 7/7 accepted after one surgical fix. |
| 2026-04-23 | save | DragonScale Memory - Phase 0 design doc (proposed) | [[DragonScale Memory]] | The Phase 0 design proposed four memory-layer mechanisms and recorded verified primary sources for dragon curve, paperfolding, LSM trees, MemGPT, and Anthropic prompt caching. |

## Key Outcomes

- The Phase 0 design proposed four memory-layer mechanisms: fold operator, content-addressable page paths, semantic tiling lint, and boundary-first autoresearch scoring (from 2026-04-23 Phase 0 design doc entry).
- The v0.2 concept revision changed load-bearing claims after adversarial review and reached 7/7 accepted after one surgical fix on tagging-scope language (from 2026-04-23 post-adversarial-review entry).
- The wiki-fold skill shipped with dry-run stdout, deterministic `fold_id`, duplicate-range detection, and a final 7/7 accept verdict (from 2026-04-23 Phase 1 entry).
- Deterministic page addresses shipped with `c-NNNNNN` format, flock-guarded allocation, counter recovery, manifest-preserved path-to-address mapping, and an 8/8 accept verdict (from 2026-04-23 Phase 2 entry).
- Semantic tiling shipped with opt-in ollama `nomic-embed-text` duplicate detection, conservative default bands, cache invalidation, locking, scale guards, and final 10/10 accept (from 2026-04-24 Phase 3 entry).
- Cross-phase hardening to v1.5.0 resolved 10 hold-ship items and added tests covering 12 shell assertions plus 18 python assertions (from 2026-04-24 Phase 3.5 entry).
- Boundary-first autoresearch shipped as v1.6.0 and the log records that all four DragonScale mechanisms are now shipped and opt-in (from 2026-04-24 Phase 4 entry).
- The v1.6.0 closeout applied all 11 verifier items across 6 files and `make test` passed with 12 shell assertions, 18 tiling assertions, and 44 boundary-score assertions (from 2026-04-24 closeout entry).

## Cross-entry Themes

- DragonScale progressed by gated phases from design proposal to shipped opt-in mechanisms (supported by: 2026-04-23 Phase 0, 2026-04-23 Phase 1, 2026-04-23 Phase 2, 2026-04-24 Phase 3, 2026-04-24 Phase 4 entries).
- Adversarial review was used as a repeated acceptance gate, with explicit accept counts recorded in concept revision, wiki-fold, address assignment, semantic tiling, Phase 4, and closeout entries (supported by: 2026-04-23 post-adversarial-review, 2026-04-23 Phase 1, 2026-04-23 Phase 2, 2026-04-24 Phase 3, 2026-04-24 Phase 4, 2026-04-24 closeout entries).
- Release hardening added tests, docs, changelog, version metadata, and guide updates around the DragonScale mechanisms (supported by: 2026-04-24 Phase 3.5, 2026-04-24 Phase 4, 2026-04-24 closeout entries).

## Contradictions or Corrections

- The 2026-04-24 closeout entry records applied corrections: install-guide wording changed from hierarchical log folds to flat extractive log folds, boundary-frontier provenance was corrected to `--top 7`, and hot.md tag wording was corrected from local tag only to local commits only. Resolution: applied in the closeout entry.
