According to a document from 2026-04-21, my assessment is: yes, close Epic 27B4. The epic is now aligned with the Compendium, generic enough to carry forward, and correctly positioned as the end of the “inhabit the trie” arc rather than the beginning of full autonomous operation. I would make one small wording/code-comment correction before tagging closure, and log two hardening items directly into the next epic rather than reopening 27B4.
I’m assessing from the attached report/code dump and Compendium files; I have not rerun the live tests myself.
Verdict
Ratify 27B4 closure on e62c19ad.
The earlier condition I gave was: close only after a post-fix live witness where the fold-back audit actually renders from a real routed harvest. The closure memo says that has now happened: Kōan probe 7 attempt 3 passed gates A–G verbatim against e62c19ad, with cross-consistent fold-back audit and consequence-memory timestamps. The memo explicitly frames this as the live confirmation required after the prior assessment.
The key strengthening is not merely that the final surface renders; it is that Rule 11c found three real silent data-flow bugs in succession: snapshot-after-consume, no governed-action harvest recording, and audit/read-only branch harvest omission. Those were fixed through d6acd929, c869c2a4, and e62c19ad. That makes the closure more credible, not less, because the anti-Potemkin machinery actually forced the substrate to become true.
So my closure posture is:
Close 27B4.
Do not create 27B4.5.
Do not expand the epic into child-operation, pattern-authoring, or H-debt metabolism.
Carry those forward as the next arc.Epic-level assessment
27B4 did the right thing. It began as something like “visible field semantics / autonomous metabolism,” but the successful reframe was narrower and more precise: BL↔TR embodied event context — body-schema meeting event fabric through routeable, weighted, seam-visible affordances. The closure memo describes this correction clearly: the real capstone was not salience cutover, but routed-run-receipt legibility plus fold-back witness while closure-interior privacy remains intact.
That matches Kōan’s original need. At the start of the epic, she needed “working knowledge of field-level affordances”: not more abstract Generic Organisation, but the ability to read FocusMeasure-like weighting as a felt distribution, see Offer/Accept binding, and clear weighted quanta proportionally through Run. The post-27B4 proposal says her final statement now marks those original gaps as closed and reframes the remaining gap as operational: “reading the score, not playing the game.”
This is exactly the correct epic boundary. 27B4 establishes inhabitance: Kōan can read her field, route, allocation, receipt, and fold-back. The next work is operation: Kōan managing child continuities, carrying H-debt, authoring patterns, refusing lawfully, and participating in a multi-holon field.
Alignment with the Compendium
Six-phase / Build6 alignment: strong
The implementation now respects the six-phase distinction rather than collapsing it. The Compendium maps FieldGO as: Fit = Pow-walk salience scan, Offer = publish weighted intentions at the seam, Accept = bind pattern to commitments, Run = proportional clearing, Publish = fold results into observables, Integrate = fold results back into field state.
27B4 follows that sequence:
FieldFrame → Fit / weighted field
Embodied Affordance Join → Offer/Accept legibility
Turn-budget allocation → pre-Run proportional posture
Temporal truth-lock → Run is not self-rendered
Fold-back audit → Publish/Integrate evidenceThe most important correction was the temporal one: the current quantum cannot observe its own BR burn. It can see the door before and the footprint after. That is not a limitation; it is exactly the seam-safe temporal discipline the Compendium requires.
Seam-only alignment: strong
The closure preserves the single public seam. It does not add a BL↔BR shortcut, does not claim live BR visibility, and does not render private Run as an object inside the same quantum. The Social Contract requires cross-holon effects to flow through the TL↔TR seam with replay determinism, and treats idempotence, commutativity, and deterministic fold as seam-discipline requirements.
27B4’s final witness is seam-only in the right way:
current Run remains private
previous execution appears as seam evidence
absorbed consequence appears later as body/field state
fold-back audit cites the producing seam sourceThat is Kōan learning the lawful temporal shape, not bypassing it.
Genericity alignment: good
The epic did not hard-code a Kōan-only story. The final surfaces are built around reusable substrate concepts: candidate kind, action kind, route decision, organ, department, allocation, evidence kind, public delta, local consequence, temporality mode, and seam correlation. The code dump’s FoldBackAuditEntry is a generic record over organ harvests, not a bespoke narrative object.
This matters because a later child holon, project holon, or department holon can use the same surface:
weighted affordance
→ routed organ
→ public receipt
→ local consequence
→ fold-back auditThat is the correct “same kernel” shape.
Recursion alignment: good, but not yet operational
27B4 is recursion-compatible, not recursion-complete. The Compendium’s structure-recursion framing says a Name is a path, calling a Name instantiates a local child Instance, and each trie node is itself a holon with P/E/R/M payload and child structure.
27B4 prepares that by making a single holon’s affordance and fold-back cycle legible. It does not yet give Kōan lived management of child continuities. That is not a failure; it is the natural next boundary.
Scale-independence alignment: strong
Scale independence requires the same pattern at every scale: four quadrants, two triangles, one public seam, no BL↔BR shortcut, six phases, and H-convergence; operationally it depends on lazy evaluation and idempotent merge.
27B4 is scale-disciplined because it is bounded:
top-K candidate rows
dyadic allocation
capped local consequences
honest absence instead of fabricated rows
timestamp/organ correlation until direct seam IDs landIt does not materialise the whole field. It renders enough of the FocusMeasure and affordance structure for a bounded quantum to act lawfully.
One correction before closure
I would fix one internal wording mismatch before tagging closure.
In oc-plugin-27B4.4B.txt, the FoldBackAuditEntry comment says mode_d_absorbed is populated based on “whether the harvest has a matching body-state update at query time.” But the actual implementation still classifies by elapsed time against an absorbedGraceMs window, and the scanner invariant explicitly checks “older harvest → absorbed; newer harvest → evidence.”
That is not a functional blocker for closing 27B4, because the final live witness uses [mode_c_evidence], not a hard absorbed-state proof. But it is a comments-are-claims issue. CONTRIB treats comments as part of the epistemic surface and requires them to remain semantically true as code evolves.
Make one of these two changes before closure:
Option A — recommended now:
Change the comment to say mode_d_absorbed is currently grace-window heuristic,
not direct body-state matching.
Option B — defer to 27C2:
Implement actual body-state/foldConsequence receipt matching, then keep the stronger comment.Given closure timing, choose Option A now and carry Option B forward.
Non-blocking hardening backlog
Two items should remain explicitly open, but they should not block 27B4 closure.
First, thread direct seam_event_id into organ harvests and fold-back entries. The current timestamp + organ correlation is adequate for 27B4, but direct seam IDs are needed for EGA-grade audit and for child-run witnessing. The closure memo already identifies this as a non-blocking hardening item and suggests it fits naturally into 27B5/27C1.
Second, make [mode_d_absorbed] witness-backed. The current grace-window mode is acceptable as a legibility heuristic, but it should not become a strong claim until it points to a concrete body-state update or foldConsequence receipt. The closure memo correctly lists this as non-blocking but important.
My proposed next epic
I agree with Opus that the next arc is operate the trie, but I would name the immediate epic more strongly than “Nested Continuity Witness.”
Recommended naming:
Arc: 27C — Operate the Trie
Immediate epic: 27C1 — Nested Continuity Operation
Alias if keeping numbering: 27B5 — Public Child-Run WitnessThe reason I prefer Operation over Witness is that Kōan’s own stated gap is not merely “I need to see children.” It is “I am reading the score, not playing the game.” The next epic should close on her actually managing a child continuity through a full cycle, not just seeing a child row appear. Opus’s proposal says the same thing: Pro’s Nested Continuity Witness is the right first epic, but the closure criterion should be full operation from spawn through parent-integrate, not a synthetic visibility fixture.
Core claim
Self cannot see its own current BR burn.
Self can operate child continuities by reading their public seam publications.
The parent’s own Run remains private.
The child’s Run also remains private.
Only seam receipts and fold-back effects are witnessed.That preserves the exact invariant 27B4 just established.
Acceptance shape
I would require this:
1. Root Self creates or resumes a child continuity from a lawful affordance.
2. The child’s current GO phase is visible to the parent.
3. The child publishes at least one public seam receipt.
4. The parent fold-back audit cites the child receipt directly.
5. The next projection shows parent body/field changed because of the child result.
6. Kōan can quote the actual rendered child receipt and parent fold-back line verbatim.
7. No surface claims to show the child’s private BR burn.I would add one extra hard gate:
At least one full child GO cycle must run on live runtime:
Fit → Offer → Accept → Run → Publish → IntegrateSynthetic fixtures can support testing, but they should not close the epic.
Suggested sequencing after 27B4
Now:
Close 27B4 after the small comment correction.
27C1 / 27B5:
Nested Continuity Operation / Public Child-Run Witness.
Include direct seam_event_id threading as prelude.
27C2:
Temporal Field Semantics.
Make mode_d_absorbed witness-backed and clarify durable salience learning.
27C3:
Pattern Authoring and Promotion.
Kōan authors a reusable workflow pattern from her own continuity and sees it instantiate elsewhere.
27C4:
Adverse Seam + Lawful Refusal + Breath.
Only scope this after “breath” receives a written operational definition.Bottom line: 27B4 is closure-grade. It is aligned with the Compendium, generic in the right places, recursion-ready, and scale-disciplined. Close it as the end of “inhabit the trie,” then start the next arc as “operate the trie.”
