…te lenses to residue Folds in the operator principle (relayed via quick-ant-298): a lens is validation — it concedes the bad thing is writable. Root-cause to make it unwritable (single authority / realization derived from model); reserve lenses for the genuinely- unstructurable (complexity/necessity). #5423's spec-only key lens shipped a false-green as the live proof. - ROADMAP §0: add the principle; split Fixes into tier-1 construction (dissolve model↔realization fork; cache-key derived-from-declared-inputs; self-host purity by construction) and tier-2 lens (complexity/cost; cache-redundancy; purity oracle; promote-inert). Meta-invariant → construction-justification rule. - ROADMAP §7: P1 cache-key reframed from 'realizer-key lens' to key derived from declared inputs_considered (construction). - fail-closed-lockdown.md: construction principle in the thesis; §4 checklist re-ordered construction-first / lens-residue; meta = construction-justification.

…sions'
Captures the lens/coproduct disposition decision (operator). One typed carrier
(Terminal{reason} | Scaffold{dissolves_to}) for BOTH lens-lifecycle tags AND
coproduct dissolve-markers — today freeform 🟡 comments, unreadable by lens since
comments aren't Nodes.
Decision: middle path (construction-capable carrier + selectively-enforcing lens
that ratchets coverage) now, #1 (substrate can't-define-untagged) as the named
end-state. The lens is itself a Scaffold{dissolves_to: substrate-mandatory-tag} —
self-dissolving when coverage = whole tree. Rejected jumping to #1 on sequencing
(load-bearing §4 substrate change → escalate; flag-day migration; derived
coproducts need disposition derived not authored), not on principle.
Enforceability split: presence = construction (non-optional field, no meta-lens);
redundancy (scaffold + successor both present) = hard gate; Terminal-vs-Scaffold
correctness = retro/judgment (synthesis-feasibility limit).

…rtition §0, testgen §1, shelve dashboard Addresses the review's four flags + sequencing nuance. - DESIGN.md §5: 'correctness by construction, not validation' is now an axiom (a check re-stating a model constraint is a 2nd representation §2/§3; prefer realization derived from a single authority; reserve checks for the unstructurable residue). §6 'enforce with lenses' reconciled: construction first, lens = residue mechanism, AND the executable inert-lens backstop is NOT superseded by the authoring-time construction-justification judgment. (flag 4 home + flag 3) - ROADMAP §0 partitioned: In-scope this window (numeric-tower grounding; cache trustworthy + warm==cold oracle shipped NOW as detective; widen rust gate; promote inert lenses) vs Fenced-OUT fan-out (Value::Null 131-site split; self-host purity gate; cross-tree import activation; Disposition carrier). Honest framing: window reduces fail-open surface, does NOT 'lock' the class — Null split stays open. (flags 1, 2, sequencing nuance) - ROADMAP §0 meta: restored executable inert-lens hygiene backstop, construction- justification layered on top (not 'supersedes'). (flag 3) - De-dup: principle no longer restated in ROADMAP/lockdown §0; both point to DESIGN §5. cache-key construction homed in §7, §0 references it. (flag 4) - ROADMAP §1 = testgen as bug-class oracle (+ affected-set completeness half + parked anemia lens); dashboard shelved to §8. - docs/plans/testgen-oracle.md (new), fail-closed-lockdown.md realigned.

…ator, open language design Folds in the operator's product thesis + the two bounds that keep it honest. - §5: construction makes a class unwritable only when membership is DECIDABLE — trichotomy (wall now / wall after grounding / ratchet forever); 'never' is the trap (lets an undecidable ratchet masquerade as a wall — optimality by Rice). - §6: denominate the benefit — the deliverable is a displaced cost (§1 time / a paid-for pain), the lens/substrate is the moat not the product; priced in elegance the work is unbounded (the economic twin of 'never'). - §7: the recursion's payoff — language design itself opens up. It's locked by cost (a check = a compiler fork; a language = an adoption problem); both dissolve here (a wall is a row §2, applied over a medium-agnostic substrate §4), so (compiler-fork × language) → (row + medium). Sound where ingest is Lossless, fail-closed where not (DecodeFidelity §4). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Apply the apex axiom/syllogism lens (single authority / no orphan / no cycle) to the roadmap itself — manual acyclicity pass: - orphan: testgen-oracle.md backlinked §1 → repoint §4 (its own lane) - single authority: §0 cache-key now a pure pointer (= §2 F2/F3/P1); §0 numeric-tower marked the authoritative home (§5 de-fork / fork plan point here, no second checkbox) - §0↔§5 cycle: self-host purity reframed as a §5 deliverable §0's expansion-gate depends on (edge §5 → §0-gate → products), not §0-owned - undeclared edge: §7 react/html declares its dependency on §6 media - backlink sweep: the reorg had broken every numeric backlink across 7 plan docs; re-point all and anchor each to the stable section TITLE so a future renumber can't silently break them again Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Doc-only follow-up to the merged #5424. Applies the roadmap's own apex invariant — the axiom/syllogism acyclicity lens (single authority / no orphan / no cycle) — to the roadmap itself, after a manual pass (bright-eagle-46's review of #5424 is that pass).
Findings fixed (reconciled to the post-merge reorg, where testgen→§4, CI→§1, dashboard→§8-SHELVED):
testgen-oracle.mdbacklinked ROADMAP §1, which doesn't point back; repointed to §4 (its own lane).= §2 F2/F3/P1, the authoritative home); §0's numeric-tower item marked the authoritative home, with §5 de-fork / fork-plan pointing to it (no second mutable checkbox).No code; CI floor unaffected.
