docs(transgenerational): M8 Phase 5 synthesis â close Phase 5 COMPLETE - #170
Merged
Conversation
M8 ran as a scoped synthesis (~3 days writing, no compute). Three high-value sub-tasks shipped (M8.2 exit-criteria walkthrough, M8.3 negative-findings synthesis with field corroboration, M8.4 Phase 6 trigger recommendation). M8.1 cross-milestone curves dropped as redundant with per-milestone logbooks 012â020. M8.5âM8.6 collapse into this commit; the original M8.7 archive step was dropped from the task slate because `openspec-archive-change` requires every task ticked â same self-blocking pattern as add-tei-prior-on-m3 § 6.10/6.11. Archive runs operator-side post-merge. Phase 5 closes COMPLETE: 2 GO (M2 Hyperparam Evolution + M3 Lamarckian Inheritance) + 3 substrate-grounded STOPs (M4 Baldwin, M5 Red Queen, M6 Transgenerational Memory) + 1 OPTIONAL deferred to Phase 6 (M7 NEAT Architecture Evolution). All five Phase 5 exit criteria MET; two with substrate-grounded STOP caveats (EC3 co-evolution, EC4 transgenerational memory) where the experiment ran honestly and produced field-consistent negative results. The three STOPs share a pattern: each is independently corroborated by 2024-2026 literature from groups working on parallel problems. M4 Baldwin substrate-constraint â Fernando 2018, Chiu 2024, Resendez Prado 2026 "transparent regime". M5 architecture-asymmetry â Resendez Prado 2026 again, Mougi 2026 trait-decoupling, Chen 2025 "Red Queen's Trap" in HFT. M6 substrate-shape mismatch â Kaletsky 2025 wet-lab single-circuit excitability + mammalian-TEI 2025 + 2024-2026 deep-RL distillation literature. Phase 5's STOPs are field-consistent substrate diagnoses, not implementation failures. Two methodology contributions ship from Phase 5 unscooped: lag-matrix cross-pairing instrument (M5 logbook 017) + cell-grid fair-test methodology + per-gen reaggregation. Each is publishable independent of any milestone's verdict. Phase 6 trigger recommendation (M8.4): defer M5 architecture-asymmetry closure to Phase 6 connectome + continuous-physics + quantum-architecture arc rather than scheduling M7 NEAT within Phase 5. M7 remains OPTIONAL in the tracker. Bio-fidelity asymmetry (NEAT is an ML tool, connectome maps to biology) + schedule efficiency + Resendez Prado's independent corroboration cover the gap. Changes: - docs/experiments/logbooks/021-phase5-synthesis.md (new, 236 lines) - docs/experiments/README.md: added entries 019, 020, 021 to active experiments table (matching the conciseness of 017/018 entries) - docs/roadmap.md: Phase 5 status ðĄ IN PROGRESS â ðĒ COMPLETE; M8 row updated with verdict + reference to logbook 021 - openspec/changes/phase5-tracking/tasks.md: scope decision documented; M8.1âM8.6 ticked off with evidence; M8.7 archive task dropped from slate per self-blocking precedent (operator-side archive after PR merge) `openspec validate phase5-tracking --strict` clean. Pre-commit clean on all touched files. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
âĶ â s + wording Independent review of feat/m8-phase5-synthesis (1-commit branch) surfaced three accuracy/honesty issues. Three should-fix items applied; two minor items skipped (out-of-scope upstream propagation); four notes confirm no blockers. F1 + F2 (citation accuracy on M3): logbook 021's EC2, milestone-slate table, and GO-results citation block attributed "+47pp / +79pp on 4 seeds" to M3 Lamarckian inheritance. These figures are actually M2 optimiser-portfolio deltas on the predator arm config M3 inherits (CMA-ES +47pp; TPE +32pp on top â +79pp; logbook 012). M3's own Lamarckian-vs-control deltas are the speed gate (+5.25 generations, 4.50 vs 9.75; threshold âĨ 4) and the +17.5pp F1-F3 retention reproduction on the M6.10 env (logbook 019 PR-A). Rewrote EC2 + milestone-slate row + GO-results citation to use the strict M3 numbers; added a citation-shorthand note in EC2 explaining the "+47pp/+79pp" propagation in upstream logbooks 018-020. The upstream artefacts are left as-is for this PR (out of scope â back-editing 4 logbooks expands the PR; flagged as a known follow-up). F3 (stale roadmap â marks): docs/roadmap.md Phase 5 Exit Criteria EC3 (co-evolution arms race) + EC4 (transgenerational memory) were bare â 'd in commit 226df23 (March 2026), BEFORE M5 and M6 STOPs landed. The M8.6 tickoff statement previously claimed "no premature â s found requiring re-verification" â that was wrong. Demoted EC3 + EC4 toâ ïļ MET WITH CAVEAT with inline cross-references to logbook 021 § M8.2 EC3/EC4, matching the honest framing the logbook itself applies. Updated tasks.md M8.6 tickoff to accurately describe the demotion rather than claim no stale â s. F5 (PR #155 â PR #138 for M3): the M3 Lamarckian inheritance pilot PR is #138, not #155 (#155 is the doc-rename PR "docs: rename OpenSpec change directories + condense experiment index"). The same "PR #155" attribution exists in upstream logbooks 019 + 020 â this PR fixes only the new reference in logbook 021; upstream is flagged as a separate follow-up doc commit (out of scope here). F4 (tighten "§ 6.10/6.11" wording in tasks.md): the M8.7 drop rationale cited "same precedent as add-tei-prior-on-m3/tasks.md § 6.10/6.11 drop". The archived add-tei-prior-on-m3 tasks.md ends at task 6.9 + a closing blockquote â there are no numbered 6.10/6.11 tasks in the literal file (they were dropped). Reworded to: "the original tasks 6.10 archive + 6.11 push were dropped from the task slate and replaced by the closing blockquote after task 6.9". Skipped: - F6 (Mougi Sci Reports URL verification) â out-of-band; URL pattern matches Nature's stable format and is project-internal-consistent with logbook 020 + tasks.md citations. - F9 (Phase 6 timeline counter-argument): acknowledged-gap-with- mitigation is a defensible synthesis choice; not a blocker. The M5 architecture-asymmetry hypothesis can be re-armed via M7 NEAT if Phase 6 slips materially â that's already implicit in M7's OPTIONAL status. No edit needed. openspec validate phase5-tracking --strict: clean. Pre-commit clean on all touched files (SKIP=tests since no Python changed).

62-62: ðĪ Low valueOptional follow-up: Propagate attribution correction to upstream logbooks.
The citation-shorthand note correctly documents that "+47pp / +79pp" are M2 optimiser-portfolio deltas, not M3's own Lamarckian-vs-control deltas. However, logbooks 018-020 and the roadmap M3 row still use this shorthand. Consider propagating the correction to those upstream artifacts for consistency.
This is flagged in the PR objectives as an outstanding operator action, so acknowledging it here for completeness.

Two PR #170 inline review findings; one applied, one skipped. Applied: - M8 header status (line 295) was still "not started" despite all M8.1âM8.6 sub-tasks being [x] complete and the milestone shipping in commit 5d562dc. Flipped to "â complete (scoped synthesis â see § Scope decision below; logbook 021 published)". - M8 OpenSpec change wording (line 294) said "(not yet created)" â forward-looking, but the change name was retired in favour of the canonical `phase5-tracking` (which IS the active OpenSpec change throughout Phase 5 and archives standalone). Aligned the two references in tasks.md to consistently say "was never created" and identify `phase5-tracking` as canonical. Both references now point future readers at the actual canonical tracker. Skipped: - Propagating the M3 +47pp/+79pp citation-shorthand fix into upstream logbooks 018/019/020 + the roadmap M3 row. Already declined in commit 7aa776c with the rationale: out of scope for this PR; back-editing 4 logbooks expands the PR; the citation- shorthand note added to logbook 021 § EC2 documents the propagation for future readers. The reviewer flagged the same finding; the same out-of-scope decision applies. `openspec validate phase5-tracking --strict` clean. Pre-commit clean (SKIP=tests, no Python changed).

The M8 header (line 294) and closing blockquote (line 309) both referenced "2026-07-21-add-phase5-evaluation" â a future-dated OpenSpec change name that was never created. Two months in the future from today (2026-05-21), the date prefix risked confusing future readers into assuming the identifier was a scheduled follow-up rather than a retired placeholder. Replaced both occurrences with the date-neutral identifier `add-phase5-evaluation` (matches OpenSpec's pre-date-prefix convention for unfinalised changes). The wording continues to state the change "was never created" and identifies `phase5-tracking` as the canonical tracker; the archive command example (`openspec-archive-change phase5-tracking`) is unchanged. `openspec validate phase5-tracking --strict` clean. Pre-commit clean (SKIP=tests, no Python changed). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Closes Phase 5 (Evolution & Adaptation) with a scoped M8 synthesis. Phase 5 ends with 2 GO results (M2 Hyperparam Evolution, M3 Lamarckian Inheritance), 3 substrate-grounded STOPs (M4 Baldwin, M5 Red Queen, M6 Transgenerational Memory), and 1 OPTIONAL milestone deferred to Phase 6 (M7 NEAT Architecture Evolution). All five Phase 5 exit criteria MET (two with substrate-STOP caveats). The STOPs are field-consistent substrate diagnoses corroborated by 2024-2026 literature; they are not implementation failures.
