Inspect whether any non-0046 percent-partition candidates are now worth a narrower contract split instead of accumulating blocker lists on one forward organ. 2. Decide whether the next substrate PR should introduce explicit typed gap records (`PF-*` codes as first-class data) or keep using stable blocker strings until the construction catalog lands. 3. If a future PR starts typed adapter work, consume `fraction_decrease` only from `ProblemFrame` facts and do not reparse raw text inside any adapter or derivation organ. --- ## Known Hazards / Do Not Touch - Do not edit `generate/derivation/*` or `generate/math_candidate_graph.py` to “finish” this slice. This PR is diagnostic-only and already proved serving parity. - The new builder logic is intentionally narrow. Do not generalize `decrease_to_fraction` into `decrease by`, percent change, or affine fraction comparison without a separate contract/confuser pack. - `percent_partition` is now deliberately stricter. A runnable-count drop elsewhere is acceptable if it removes false readiness; do not loosen obligations to make the number larger. - `HANDOFF-gpt55-2026-06-20.md` was replaced; do not rely on the earlier planning-only contents. --- ## Architectural Decisions Made This Session - `BoundQuestionTarget` now carries typed operator/state/direction, with validation that blocks illegal delta/final combinations at construction time. - `decrease_to_fraction` is represented as a span-grounded `BoundRelation` in `ProblemFrame`, not as a derivation-organ shortcut. - Readiness is keyed to exact grounded IDs from the frame. Repeated entity mentions are canonicalized at relation construction so contracts can match by identity rather than lowercase text equality. - `percent_partition` requires a forward aggregate target and an original whole bound before subgroup events. Final-state/inverse prompts are blocked rather than treated as forward partition. - Adequacy and morphology reports now expose blocker combinations by organ, making false readiness auditable without touching serving. --- ## What Must Not Be Forgotten The substantive result of this session is not just “0005 runnable.” It is that `runnable` now means obligation-closed from `ProblemFrame` evidence alone: `0005` closes through `decrease_to_fraction`, `0046` closes only under explicit complementary-subgroup topology, and `0393` is blocked because its target is inverse/original-whole rather than a forward aggregate. **Prompt Library Reference**: See `docs/core-rd-base-prompts.md` (especially sections #7 Standing Loop Axiom Check, #8 PR Merge-Readiness Audit, and #9 Grok Build Implementation Session). Use them as standing prefixes. --- ## Skills Used This Session - core-bootstrap: not available - versor-coherence-guardian: not available - pre-edit-sweep: manual import/call-site sweep completed - claim-proposal-guardian: not needed - Other: none --- ## Authorization Addendum — `binding.quantity_entity` foundational slice ### Agent and Session - **Agent:** gpt55 - **Date:** 2026-06-20 - **Reasoning effort used:** high - **Grok Build mode used:** Headless - **Session entry point:** authorize, but do not implement, the first bounded diagnostic proposal-first slice for `binding.quantity_entity` - **Branch:** `docs/kernel-authorize-quantity-entity-slice` - **Base:** `origin/main` at `a266324e` (merged PR #844) ### Bootstrap and base proof The session read `GPT55.md`, `AGENTS.md`, `docs/runtime_contracts.md`, and this current handoff before editing. The branch was created in a fresh worktree directly from fetched `origin/main`. `HEAD` and `origin/main` both resolved to `a266324eea5adf739b7d4e509a994c5425334b65`; the worktree was clean. The base contained the #844 merge, `_PROPOSAL_FIRST_FAMILIES`, and the `make_proposal()` rejection fence for both migrated families. ```text uv run python -m core.cli test --suite smoke -q 108 passed in 126.15s (0:02:06) ``` ### Modules touched | File | Change type | Summary | |---|---|---| | `docs/sessions/quantity-entity-foundational-slice-authorization-2026-06-20.md` | new | Defines the sole bounded future implementation authority, proposal-first seam, roles/evidence obligations, closure/refusal conditions, confuser suite, acceptance gates, validation, and next-PR brief. | | `docs/specs/foundational-families/quantity-entity-binding.md` | modified | Replaces the unconditional implementation prohibition with a narrow link to the controlling authorization while retaining non-serving status. | | `HANDOFF-gpt55-2026-06-20.md` | modified | Adds this continuity record. | ### Invariants verified - **Field closure:** Preserved by scope. No algebra, field, propagation, normalization, Vault, or runtime field-state path was modified. - **Proposal-first authority:** The authorization requires proposals to begin with `status="proposed"`; exact bindings ground; a separate `ContractAssessment` alone reports diagnostic runnable/refused. - **#844 fence:** `make_proposal()` is explicitly forbidden for the new family; future dispatch requires a pre-existing proposal. Existing #841/#842 families and their dispatch remain out of scope. - **Diagnostic-only / no serving:** The authorized future proposal must retain `diagnostic_only=True` and `serving_allowed=False`; this PR changes no code or serving path. - **Open-world truthfulness:** Ambiguity and absent evidence require refusal. Missing unit evidence cannot be converted into a count claim, and no `determine(answer=False)` path is authorized. - **Exact evidence:** Closure requires exact source-backed quantity, entity, binding, and optional-unit spans equal to original text slices. - **No broad parser / universal IR:** The future slice is bounded to existing local `ProblemFrame`, `GroundedScalar`, `GroundedMention`, `GroundedUnit`, and `MentionBinding` evidence. - **Wrong-zero:** No eval or serving files changed. The future implementation brief requires train and holdout `wrong_ids == []`. ### Subagent / Arena reconciliation - Number of subagents spawned: 0 - Each subagent independently verified versor closure: N/A - Reconciliation: N/A ### Tests run ```bash # exit 0 — 108 passed uv run python -m core.cli test --suite smoke -q # exit 0 — 28 passed uv run python -m pytest -q \ tests/test_foundational_families.py \ tests/test_construction_affordances.py \ tests/test_construction_proposal_seam.py # exit 0 git diff --check ``` ### Open tasks / next session entry point 1. Merge this authorization PR before beginning implementation. 2. For the next PR, use the copy-paste brief at the end of the authorization document and prove the merged authorization is present on fresh `origin/main`. 3. Do not implement `state_change.transition`; it requires separate authority. ### Known hazards / do not touch - The authorization does not permit generic entity extraction, broad noun parsing, a universal IR, event semantics, answer production, or serving. - `quantity_kind` must be positively grounded. Unit absence alone is not proof of a count construction. - Local quantity/entity grounding inside a state-change sentence does not authorize transition recognition. - Do not change derivation organs, `generate/math_candidate_graph.py`, eval or sealed artifacts, reports, packs, policy, identity, recall, Vault, field, algebra, or serving runtime under this authorization. ### Architectural decision The first family is a provenance-preserving local bipartite binding with a conjugate assessment, not an entity parser. Proposal and assessment remain separate authorities: proposal carries a hypothesis forward; assessment opposes it when topology or evidence is not uniquely closed. ### What must not be forgotten This authorization is effective only after merge and only for `binding.quantity_entity`. It authorizes one diagnostic proposal-first slice; it does not authorize `state_change.transition`, serving, general entity extraction, or broad parsing. **Prompt Library Reference**: See `docs/core-rd-base-prompts.md` (especially sections #7 Standing Loop Axiom Check, #8 PR Merge-Readiness Audit, and #9 Grok Build Implementation Session). Use them as standing prefixes. ### Skills used - core-bootstrap: unavailable; checklist completed manually - versor-coherence-guardian: unavailable; closure preserved by docs-only scope and smoke validation - pre-edit-sweep: completed manually over ADRs, specs, typed substrate, proposal/assessment seams, and focused tests - claim-proposal-guardian: unavailable; proposal authority and #844 fence verified manually and with focused tests - Other: none --- ## PR #841 Addendum — feat(kernel): route proportional-decrease through proposal-first seam ### Agent and Session - **Agent:** gpt55 - **Date:** 2026-06-20 - **Reasoning effort used:** high - **Grok Build mode used:** Headless - **Session entry point:** Migrate only `proportional_change.decrease_to_fraction` from assessment-backed proposal synthesis to the ADR-0223/0224 proposal-first construction seam without changing serving or derivation. - **Branch:** `feat/kernel-proportional-decrease-proposal-first` - **Base:** `origin/main` at `168c9f26ac3deb8037d4eb7bca77c33dc9d5ff62` ### Smoke Suite + Bootstrap Status ```text uv run python -m core.cli test --suite smoke -q 108 passed in 123.41s (baseline) 108 passed in 123.05s (post-edit) ``` The GPT55.md startup checklist was completed manually. The Codex worktree was clean and `HEAD == origin/main` before edits. `/Users/kaizenpro/Projects/core` was not modified, stashed, reset, cleaned, or reconciled. ### Modules Touched | File | Change type | Summary | |---|---|---| | `generate/construction_affordances.py` | modified | Added a pre-assessment catalog proposal factory; proposals now carry immutable role obligations and enforce diagnostic-only / serving-disallowed posture. Retained the assessment-backed adapter only for unmigrated catalog paths. | | `generate/problem_frame.py` | modified | Let `ProblemFrameBuilder` accumulate proposals before relation binding. | | `generate/problem_frame_builder.py` | modified | Produces the proportional-decrease proposal from the exact existing surface chunk before mention/relation binding and assessment; preserves assessment-backed traces for other families. | | `generate/problem_frame_contracts.py` | modified | Routes fraction-decrease assessment from proposal metadata read-only while leaving `assess_fraction_decrease` obligations unchanged. | | `tests/test_construction_affordances.py` | modified | Covers the pre-assessment factory, catalog role obligations, and serving posture. | | `tests/test_proportional_decrease_proposal.py` | modified | Proves proposal-before-assessment order, exact span grounding, proposal-driven dispatch, unchanged contract refusal, and confuser blocking. | | `HANDOFF-gpt55-2026-06-20.md` | modified | Added this PR #841 continuity record. | ### Invariants Verified - **Field closure:** Preserved by construction. No algebra, field, propagation, normalization, vault, or runtime field-state code changed. - **Exact recall:** Preserved. No recall path, cosine, ANN, HNSW, or stochastic retrieval was added. - **Proposal/binding/contract separation:** The proposal begins as `status="proposed"`; only `ContractAssessment` determines runnable/refused state from bound relations and question-target evidence. - **Catalog and serving gates:** Proposal role obligations and posture come from the existing catalog; `diagnostic_only=True` and `serving_allowed=False` are enforced on the proposal type. - **Controlled migration:** Only proportional decrease is proposal-first. Percent partition retains its existing assessment-backed trace; no foundational family gained implementation authorization. - **No universal IR / no live-CGA claim:** The patch reuses `ConstructionProposal`, `ProblemFrame`, `BoundRelation`, and `ContractAssessment`; it adds no new carrier and makes no substrate-retrieval claim. - **Serving parity:** Train remained `30 correct / 20 refused / 0 wrong`; holdout remained `5 correct / 495 refused / 0 wrong`; both wrong-id lists were empty. - **Diagnostic parity:** Train remained 2 runnable contracts (`0005`, `0046`); holdout remained 0 runnable contracts. ### Subagent / Arena Reconciliation - Number of subagents spawned: 0 - Each subagent independently verified versor closure: N/A - Reconciliation: N/A ### Tests Run ```bash # exit 0 — 55 passed uv run python -m pytest -q \ tests/test_construction_affordances.py \ tests/test_foundational_families.py \ tests/test_problem_frame_builder.py \ tests/test_problem_frame_contracts.py \ tests/test_proportional_decrease_proposal.py \ tests/test_kernel_no_new_legacy_derivation_surfaces.py # exit 0 — 108 passed uv run python -m core.cli test --suite smoke -q # exit 0 — serving parity # train: {'correct': 30, 'wrong': 0, 'refused': 20}; wrong_ids: [] # holdout: {'correct': 5, 'wrong': 0, 'refused': 495}; wrong_ids: [] # exit 0 — diagnostic parity # train contract_runnable_count: 2; ids: 0005, 0046 # holdout contract_runnable_count: 0 # exit 0 uv run python -m compileall -q \ generate/construction_affordances.py \ generate/problem_frame.py \ generate/problem_frame_builder.py \ generate/problem_frame_contracts.py # exit 0 git diff --check ``` ### Open Tasks / Next Session Entry Point 1. Review the six implementation/test files and publish PR #841 with the brief's required body sections. 2. Keep percent partition assessment-backed until a separately authorized proposal-first migration. ### Known Hazards / Do Not Touch - Do not map `ConstructionProposal.status` to fraction assessment output again; that recreates the assessment-first inversion. - Do not generalize the reused `decrease to of` recognizer into generic state change, acquisition, or transaction behavior. - Do not connect foundational-family registry metadata to runtime authorization or serving. - Do not edit derivation, candidate graph, eval cases, reports, packs, policy, identity, recall, field, or algebra for this slice. ### Architectural Decision The proposal is the construction hypothesis, not a cached verdict. It carries the catalog's obligations and exact motivating chunk. `BoundRelation` grounds those obligations, and the existing `ContractAssessment` remains the corrective/conjugate stage that closes or refuses the hypothesis. Other families are deliberately left on the legacy assessment-backed adapter to keep this migration singular. ### What Must Not Be Forgotten PR #841 proves the ordering `surface chunk → proposed construction → span-grounded relation → ContractAssessment` for proportional decrease only. A positive proposal is not serving authorization, is not a runnable verdict, and is not evidence that general CGA/substrate retrieval is live. ### Skills Used - core-bootstrap: unavailable; checklist completed manually - versor-coherence-guardian: unavailable; closure preserved by scope and smoke validation - pre-edit-sweep: completed manually across imports, callers, tests, evals, calibration, and scripts - claim-proposal-guardian: unavailable; proposal posture and assessment separation verified directly - Other: none --- ## PR #836 Addendum — feat(kernel): introduce construction-affordance catalog skeleton ### Agent and Session - **Agent:** Antigravity (Gemini 3.5 Flash) - **Date:** 2026-06-20 - **Task:** Implement `feat(kernel): introduce construction-affordance catalog skeleton` (PR #836) - **Branch:** `feat/kernel-construction-affordance-catalog` ### Modules Touched / Created | File | Change type | Summary | |---|---|---| | `generate/construction_affordances.py` | NEW | Frozen, typed structures (`RoleObligation`, `ConstructionHazard`, `ConstructionSignature`, `ConstructionFamily`, `ConstructionContract`, `ConstructionProposal`) and initial catalog registry with two diagnostic families (`proportional_change.decrease_to_fraction` and `partition.percent_partition`). | | `generate/problem_frame_contracts.py` | modified | Added `_CONTRACT_REGISTRY` mapping candidate organs to ConstructionContract;

Review and publish PR #840 with the required body sections from the implementation brief. 2. Do not connect this registry to `ProblemFrame`, `ContractAssessment`, proposal routing, recognition, adapters, or serving without a separately authorized behavior PR. ### Known Hazards / Do Not Touch - The two #839 specifications are gating artifacts, not implementation authorization. - Do not parse `docs/specs/foundational-families/*.md` at runtime. - Do not add acquisition, transaction, another family, or a universal family IR in this slice. - The acknowledged local-only state under `/Users/kaizenpro/Projects/core` remains outside this PR and must not be altered. ### Architectural Decision The foundational registry remains separate from `ConstructionFamily`. The latter describes live diagnostic construction proposals; this schema mirrors constitutional family gates. Combining them would falsely couple specification completeness to executable assessment machinery and blur current versus target state. ### What Must Not Be Forgotten PR #840 makes the family-spec gate structurally inspectable; it authorizes nothing. Both entries remain non-serving and non-implementable until a separate evidence-backed PR is approved. ### Skills Used - core-bootstrap: unavailable; checklist completed manually - versor-coherence-guardian: unavailable; closure preserved by scope and smoke validation - pre-edit-sweep: completed manually across imports/call sites in `generate/`, `tests/`, `evals/`, and `calibration/` - claim-proposal-guardian: not needed; no claim or proposal mutation path touched - Other: none --- ## PR #842 Addendum — feat(kernel): route percent-partition through proposal-first seam ### Agent and Session - **Agent:** gpt55 - **Date:** 2026-06-20 - **Reasoning effort used:** high - **Grok Build mode used:** Headless - **Session entry point:** migrate only `partition.percent_partition` from process-frame-triggered assessment dispatch to the ADR-0223/0224 proposal-first construction seam, without changing serving or derivation organs - **Branch:** `feat/kernel-percent-partition-proposal-first` - **Base:** `origin/main` at `955fec3b` (merged PR #841) ### Smoke Suite + Bootstrap Status ```text uv run python -m core.cli test --suite smoke -q 108 passed, 1 warning in 128.03s (0:02:08) ``` The warning reports an existing `engine_state` checkpoint revision mismatch (`4bab1638` versus `955fec3b`); no engine-state or runtime file was modified. `core-bootstrap` was unavailable as a skill, so the `GPT55.md` checklist was completed manually: `GPT55.md`, `AGENTS.md`, `docs/runtime_contracts.md`, and the current handoff were read; baseline state and branch ancestry were inspected; the pre-edit import/call-site/test sweep was completed. ### Modules Touched | File | Change type | Summary | |---|---|---| | `generate/problem_frame_builder.py` | modified | Added a narrow pre-assessment percent-partition proposal factory requiring an existing partition/consumption process cue plus explicit `N% of` evidence; attaches the proposal before mention/relation binding and contract assessment. | | `generate/problem_frame_contracts.py` | modified | Replaced percent-partition process-frame-name dispatch with catalog-family proposal-gated dispatch; left `assess_percent_partition()` structurally unchanged. | | `tests/test_percent_partition_proposal.py` | new | Proves proposal posture/obligations/order, exact evidence spans, legacy-adapter exclusion, assessment authority, no-proposal dispatch refusal, and percent-change confuser refusal. | | `HANDOFF-gpt55-2026-06-20.md` | modified | Added this PR #842 continuity record. | ### Invariants Verified - **Field closure:** Preserved by scope and smoke. No algebra, field, propagation, normalization, vault, or runtime field-state path was touched; no field operator was added. - **Proposal/grounding/contract duality:** `propose_construction()` creates only `status="proposed"`; exact bound relations remain grounding evidence; `assess_percent_partition()` remains the only runnable/refused authority. - **Diagnostic-only / serving forbidden:** Catalog-derived proposal retains `diagnostic_only=True` and `serving_allowed=False`; serving train/holdout results are byte-equivalent in outcome counts with `wrong_ids == []`. - **No legacy adapter for migrated families:** Focused regression makes `make_proposal()` fail if percent partition reaches it; the supported path remains green. - **No broad parser or state-change runtime:** Proposal recognition is limited to the existing partition/consumption process cue plus explicit `N% of` surface evidence. The percent-change confuser can be proposed as a hypothesis but is contract-refused. - **Exact recall / epistemic / identity:** No recall, CGA ranking, ANN/cosine, teaching mutation, pack, policy, identity, or epistemic transition path was touched. - **Diagnostic readiness:** Train runnable count remains `2`; holdout runnable count remains `0`. ### Subagent / Arena Reconciliation - Number of subagents spawned: 0 - Each subagent independently verified versor closure: N/A - Reconciliation: N/A ### Tests Run ```bash # exit 0 — 54 passed uv run python -m pytest -q \ tests/test_construction_affordances.py \ tests/test_problem_frame_builder.py \ tests/test_problem_frame_contracts.py \ tests/test_proportional_decrease_proposal.py \ tests/test_percent_partition_proposal.py \ tests/test_kernel_no_new_legacy_derivation_surfaces.py # exit 0 — 108 passed, one pre-existing state-revision warning uv run python -m core.cli test --suite smoke -q # exit 0 uv run ruff check \ generate/problem_frame_builder.py \ generate/problem_frame_contracts.py \ tests/test_percent_partition_proposal.py # exit 0 uv run python -m compileall -q \ generate/construction_affordances.py \ generate/problem_frame.py \ generate/problem_frame_builder.py \ generate/problem_frame_contracts.py # exit 0 — train serving parity # {'correct': 30, 'wrong': 0, 'refused': 20}; wrong_ids == [] # exit 0 — holdout serving parity # {'correct': 5, 'wrong': 0, 'refused': 495}; wrong_ids == [] # exit 0 — diagnostic readiness # train contract_runnable_count == 2 # holdout contract_runnable_count == 0 # exit 0 git diff --check ``` ### Open Tasks / Next Session Entry Point 1. Review the four changed files, commit intentionally, push `feat/kernel-percent-partition-proposal-first`, and open PR #842 using the brief's required body sections. 2. Leave `make_proposal()` cleanup for a separate small follow-up; both catalog families now bypass it, but deletion was intentionally not mixed into this migration. ### Known Hazards / Do Not Touch - Do not broaden `_PERCENT_OF_PROPOSAL_RE` into general percentage or state-change recognition. Proposal closeness is intentionally narrower than contract authority. - Do not weaken `assess_percent_partition()` obligations to recover diagnostic counts; its whole/part/scale topology and forward-target checks remain load-bearing. - Do not connect this diagnostic proposal to serving, derivation organs, `math_candidate_graph`, foundational-family implementation, pack mutation, or runtime admission. ### Architectural Decision Percent partition now follows the same ordering proven by PR #841: `surface/process cue → proposed ConstructionProposal → bound percent/subgroup relations → ContractAssessment`. Process-frame similarity authorizes only a hypothesis; exact span bindings ground it; the organ-specific contract determines closure or refusal. ### What Must Not Be Forgotten Both construction-affordance catalog families are now proposal-first, but proposals remain diagnostic-only and serving-disallowed. `ContractAssessment`, not `ConstructionProposal`, is the executable readiness authority. **Prompt Library Reference**: See `docs/core-rd-base-prompts.md` (especially sections #7 Standing Loop Axiom Check, #8 PR Merge-Readiness Audit, and #9 Grok Build Implementation Session). Use them as standing prefixes. ### Skills Used - core-bootstrap: unavailable; checklist completed manually - versor-coherence-guardian: unavailable; closure preserved by scope and smoke validation - pre-edit-sweep: completed manually across imports, callers, tests, `evals/`, and `calibration/` - claim-proposal-guardian: unavailable; proposal status and serving posture verified through catalog/focused tests - Other: none --- ## Latest continuity pointer The latest session on 2026-06-20 is the `binding.quantity_entity` authorization addendum above. It starts from merged #844 at `a266324e` on branch `docs/kernel-authorize-quantity-entity-slice`. The controlling artifact is `docs/sessions/quantity-entity-foundational-slice-authorization-2026-06-20.md`. Merge that documentation PR before starting the bounded diagnostic-only implementation brief. No `state_change.transition`, serving, general entity extraction, or broad parsing work is authorized. ### GSM8K train proxy rebaseline status (post-#847) PR #847 restored `evals/gsm8k_math/train_sample/v1/report.json` to the governed 6/44/0 pin after #846 committed a 30/20/0 rebaseline without explicit authorization. A dedicated rebaseline PR (`chore/evals-ratify-gsm8k-train-proxy-rebaseline`) was opened against the #847 merge commit (`b6d42283`) to ratify the committed 30/20/0 counts. That PR is the explicit authorization boundary for this rebaseline. **Ratified counts:** `correct: 30, refused: 20, wrong: 0`, `wrong_ids: []`. **Controlling artifact:** `docs/sessions/gsm8k-train-proxy-rebaseline-2026-06-20.md`. **No runtime, serving, teaching, or capability change in this rebaseline PR.** ### Workbench / UI Alignment Scope Note The alignment scope for the CORE Workbench/UI under the latest proposal-first pivots is documented in `docs/sessions/workbench-proposal-first-alignment-scope-2026-06-20.md`. This is a docs-only session note that identifies UI gaps, non-goals, future acceptance criteria, and next PR briefs to align the frontend observatory with the backend's proposal-first and contract assessment authority architecture. --- ## Unary state-change delta authorization pointer The 2026-06-21 design investigation found that broad `state_change.transition` is not one safe organ. It combines unary delta, binary transfer, containment movement, and before/after state topology. Authorized for one future diagnostic-only implementation PR: - `state_change.unary_delta` only; - exact cue inventory `gained → increase`, `lost → decrease`; - one exact scalar/object `quantity_entity` edge; - one family-local exact action-cue record; - `ConstructionProposal(status="proposed")` before binding; - `ContractAssessment` as the sole runnable/refused authority; - `diagnostic_only=True`, `serving_allowed=False`. Explicitly not authorized: broad `state_change.transition`, transfer, containment, before/after state, measurement delta, actor/owner inference, coreference, cross-sentence binding, arithmetic, answers, serving, derivation ledger integration, or quantity-family widening. Controlling artifacts: - `docs/sessions/unary-state-change-delta-authorization-2026-06-21.md` - `docs/sessions/unary-state-change-delta-preflight-2026-06-21.md` - `docs/specs/foundational-families/unary-state-change-delta.md` The next PR should implement the preflight's copy-paste brief. Stop if it requires changes to `_quantity_entity_proposals()`, `_quantity_kind_dispositions()`, `generate.derivation.state`, actor/owner parsing, a broader cue inventory, synthetic spans, serving paths, or any non-empty wrong-ID list. Validation performed in the fresh worktree: startup guard passed with `HEAD == origin/main == ca83d384`; baseline and post-doc `uv run python -m core.cli test --suite smoke -q` completed successfully; requested positive/confuser ProblemFrame probes were run read-only; `git diff --check` passed. No subagents were used.
