ADR-0243 Phase 3 — Lane Brief Pack

Status: ready for dispatch (Shay's call — see feedback-no-self-dispatch-of-subagents) Plan of record: docs/plans/adr-0243-implementation-plan.md §5 Phase 3 Phase 2 status: merged to main (PR #56, merge commit 8624ea9a) — cognitive_lifecycle.py is on main now. The feature branch was deleted post-merge; do not branch off it. All three lanes below branch directly off current forgejo/main.

Each lane's research below was run fresh against the worktree on 2026-07-17 (three read-only Explore passes, not assumed from the plan text) — one correction to the plan doc's substrate table came out of it and has already been applied (§2.3 readback rules row; packs/en/readback_rules.py doesn't exist, it was deleted under audit ratchet W-006).

Dependency DAG — corrected from the plan's "all wait on Phase 2" framing

The plan text implies all three lanes start "after Phase 2 API lands." That was only ever true for one of them, and Phase 2 has since merged (#56) — so as of now, all three are unblocked and start from the same place:

• Lane A (discovery wiring) and Lane C (biography wiring) touch zero Phase-2 code — every symbol they wire predates this arc (core/physics/surprise.py, core/physics/multi_scale_energy.py, core/physics/goldtether.py, core/contemplation/runner.py, teaching/discovery.py, evals/analogical_transfer/harness.py, core/physics/biography.py).
• Lane B (sensorium corridor eval) is the only lane that imports core.physics.cognitive_lifecycle (CognitiveLifecycleEngine, ingest_context, egress_gate) — it needed Phase 2 merged first. It now is.

Wave 1 (parallel, all off forgejo/main now):
  Lane A — discovery wiring
  Lane B — sensorium corridor eval
  Lane C — biography wiring

All three are independent PRs — no lane blocks another.

Bundling options

• Max parallelism (3 PRs, recommended): one operator per lane, dispatched as below.
• Substrate-first (2 PRs): bundle A+C (both off main today, both "wire an existing pinned primitive into a live call site") into one PR; B stays separate since it has the Phase-2 dependency and is the larger deliverable (new eval package).
• All-in-one (1 PR): only if Phase 2 merges first and you want one operator to do all three sequentially — loses the parallelism that's the whole point of splitting these out.

Must-read memories (every operator, before touching code)

feedback-start-in-worktree-off-main, feedback-parallel-agent-worktrees, feedback-no-self-dispatch-of-subagents, feedback-core-main-diverges-from-forgejo-truth (base/diff against forgejo/main, never local main), feedback-smoke-gate-not-full-suite (run this lane's own tests locally on the rebased base before flagging ready), feedback-cleanup-as-you-find, feedback-adr-cross-reference-discipline (grep ALL ADRs + code for existing mechanisms before adding anything that looks new — this pack's whole point is that most of the "new" wiring in Lanes A/C is one missing call, not new architecture).

---

Brief A — Discovery wiring (surprise → contemplation → DiscoveryCandidate)

Base: forgejo/main @ 19819194. Branch: feat/adr-0243-phase3-lane-a-discovery. Worktree: git worktree add ../core-adr0243-lane-a feat/adr-0243-phase3-lane-a-discovery (create the branch first off forgejo/main, then add the worktree).

Outcome

core/contemplation/runner.py's finding-processing path calls is_discovery_eligible (core/physics/surprise.py:206) and, when eligible, cross_band_discovery_gate (core/physics/multi_scale_energy.py:276) to decide whether to construct and emit a DiscoveryCandidate (teaching/discovery.py:149) through the existing DiscoveryCandidateSink protocol (teaching/discovery_sink.py:29, one method: emit(self, line: str) -> None). Separately, wire a live caller of propose_kappa_line_search (core/physics/goldtether.py:567) so its internal kappa_search_event call (line 604) actually fires — confined to a calibration/training-loop call site, never a hot/serve path (R-04: docs/analysis/core_cohesion_master_plan.md:337, "trace generation... limited strictly to the calibration and training-loop pipelines").

Open question — resolve before writing code, don't guess

is_discovery_eligible requires surprise_norm: float and productive_or_transfer: bool. Neither is obviously present on whatever finding type core/contemplation/runner.py processes today (_emit_findings, runner.py:32-51). Read the actual finding dataclass(es) the runner consumes before wiring anything — if no surprise score is computed at this point in the pipeline, that's a real gap to report back, not something to fabricate a plausible-looking number for.

Hard requirements

1. Do not change is_discovery_eligible or cross_band_discovery_gate's signatures — both are ADR-0242 §5 pinned primitives with existing tests (tests/test_adr_0242_carry_seams.py).
2. Construct DiscoveryCandidate through the existing dataclass (teaching/discovery.py:149) — no parallel candidate type.
3. kappa_search_event stays calibration/training-loop only (R-04) — if you can't find an existing calibration entry point to hang the caller off, say so rather than inventing a new hot-path call site.
4. Emitting a DiscoveryCandidate is proposal-plumbing, not a vault write — the only side effect should be sink.emit(...) (JSONL append via DiscoveryMonthlyFileSink or in-memory DiscoveryBufferSink).
5. No changes to core/physics/cognitive_lifecycle.py — this lane is orthogonal to Phase 2.

Tests

• Must stay green: tests/test_adr_0242_carry_seams.py
• New: a high-surprise contemplation finding produces a DiscoveryCandidate on the sink; a low-surprise one does not.
• New: propose_kappa_line_search's live caller fires kappa_search_event only from the calibration path.

Forbidden actions

Touching chat/runtime.py's serve path. Building a new always-on scheduler (out of scope for this lane — flag it if you think the wiring needs one, don't build it).

Deliverables

Runner wiring change (likely core/contemplation/runner.py), the live propose_kappa_line_search caller, new test file(s).

Operator profile

Real open design question (surprise-signal sourcing) — strong-reasoning tier suggested.

---

Brief B — Sensorium corridor eval (first live I-04 consumer)

Base: forgejo/main (Phase 2 merged as of #56 — cognitive_lifecycle.py is on main). Branch: feat/adr-0243-phase3-lane-b-corridor. Worktree: git worktree add ../core-adr0243-lane-b -b feat/adr-0243-phase3-lane-b-corridor forgejo/main.

Outcome

New eval package evals/adr_0243_cognitive_lifecycle/, shaped like evals/adr_0242_v2_energy_compare/ (thin __init__.py with a run_fixed_replay(...) -> dict entry point delegating to one pure artifact function; __main__.py CLI dumping sorted-key JSON — no fixture files, deterministic parametrized inputs). The corridor it exercises:

AudioCompiler.compile(...)          (sensorium/audio/compiler.py:117)
VisionCompiler.compile_tile(...)    (sensorium/vision/compiler.py:92)
        │  .versor
        ▼
packet_from_compilation_unit(modality_id, unit)   (core/physics/sensorium_wave_feed.py:151)
        ▼
CognitiveLifecycleEngine.solve(packets, domain_id, hamiltonian)  (ingress → relax → egress)
        ▼  (E3/E4 route: "readback_eligible")
generate/realizer.py:energy_modulated_surface(base_surface, energy_class)   (readback text)
        │
        └── separately, explicitly: GoldTetherMonitor.decide(...)  (core/physics/goldtether.py:451)

Hard requirements

1. OFF-SERVING. Lives under evals/ only. Never imported from chat/runtime.py. If this adds any new core.physics module (it shouldn't need to — it's composition, not a new organ), add it to tests/test_serve_quarantine_transitive.py's _BANNED tuple and tests/test_third_door_cohesion.py's banned_roots/banned_substrings.
2. Follow the adr_0242_v2_energy_compare shape — deterministic fixed-replay, one pure artifact function, no fixture files.
3. This is the first LIVE consumer of the I-04 feed (docs/analysis/core_cohesion_master_plan.md:110, non-stochastic multimodal resonance). The compilers and adapters already exist and are unit-tested (tests/test_adr_0241_sensorium_wave_feed.py:230) — do not re-implement them, import and compose.
4. Readback text goes through generate/realizer.py:energy_modulated_surface — not packs/en/readback_rules.py (deleted; plan doc §2 table corrected 2026-07-17).
5. egress_gate deliberately does not call GoldTetherMonitor.decide — it only reports the raw unitary residual it needs for its own routing. This lane calls .decide(...) explicitly as a separate step in the corridor.

Tests

• Precedent for fixture inputs: tests/test_adr_0241_sensorium_wave_feed.py:230 test_real_audio_and_vision_compilers_feed_phase_correlate.
• New: an end-to-end deterministic test exercising compiler → ingest → relax → egress → readback → GoldTether, asserting the whole chain composes without any layer silently repairing another's output.

Forbidden actions

No cosine/ANN similarity anywhere in the corridor — I-04's own definition requires algebraic phase correlation in Cl(4,1); cosine/ANN is explicitly what it rules out. No vault writes — crystallization stays proposal-only, same as Phase 2.

Deliverables

evals/adr_0243_cognitive_lifecycle/__init__.py, evals/adr_0243_cognitive_lifecycle/__main__.py, new test file(s), quarantine-list additions if applicable.

Operator profile

Mostly composition of already-tested organs — moderate tier should be sufficient, but the GoldTether/readback ordering deserves care.

Brief C — Biography wiring (ADR-0240 PASS → integrate_biography)

Base: forgejo/main @ 19819194. Branch: feat/adr-0243-phase3-lane-c-biography. Worktree: git worktree add ../core-adr0243-lane-c feat/adr-0243-phase3-lane-c-biography.

Outcome

Wire the ADR-0240 validation harness's PASS signal — AnalogicalTransferReport.wrong == 0 / .all_correct_or_refused (evals/analogical_transfer/harness.py:59-61), or per-case TransferResult.correct is True (reason="transfer_ok", harness.py:214-227) — into a live call of integrate_biography(trajectory, alpha=0.5) (core/physics/biography.py:66-70), which has zero production call sites today (test-only). Add I-01 closure asserts at the call site (blade.closure < _CLOSURE and versor_condition(blade.blade) < _CLOSURE — model on tests/test_third_door_cohesion.py:195-213) and provenance recording.

Note: there is no literal PASS type/enum in the harness — that word in the plan text is a paraphrase. The actual signal is report.wrong == 0 (report-level) or TransferResult.correct (case-level). Pick the granularity deliberately (report-level gates a whole session's worth of transfers into one biography integration; case-level would integrate per-transfer) and say which you chose and why.

Open question — resolve before writing the mutation path, don't guess

Does wiring ADR-0240 PASS → integrate_biography count as a persisted identity-substrate mutation, or a legitimate direct integration? biography.py's own docstring says biography holonomy is "reconstruction-over-storage... not a parallel identity store," which reads differently from the Phase 2 module's proposal-only crystallization discipline (D-5/I-03) — but that's a reading, not a ruling. Read docs/adr/ADR-0240-Analogical-Transfer-Validation-Harness-Biography-Holonomy.md in full. If it's genuinely ambiguous after that, this is an identity-substrate design call — confirm with Shay before writing the mutation path rather than picking silently.

Hard requirements

1. No existing biography-specific provenance helper exists (confirmed by grep across core/physics/*.py — goldtether.py, self_authorship.py, holographic_vault.py, wave_manifold.py all have zero provenance references). Model any new one on self_authorship.py:20-36's AuthorshipProposal shape (proposal_id, kind, epistemic_status, drift_residual, closure_proof, body, adr_refs), or on core/physics/identity.py:263's TurnEvent if you decide biography provenance is closer to a turn-scoped record. Document which you chose and why.
2. I-01 must hold at the call site itself, not just in the pre-existing unit test — assert blade.closure and versor_condition(blade.blade) against the same _CLOSURE threshold every time this wiring runs; fail closed (typed error) if not.
3. Do not change integrate_biography's signature (core/physics/biography.py:66-70) — it's fully implemented and tested. This lane adds a caller, not a rewrite.
4. Do not change the ADR-0240 harness (evals/analogical_transfer/harness.py) — consume its output as-is.

Tests

• Must stay green: tests/test_adr_0240_biography_holonomy.py, tests/test_third_door_cohesion.py::test_i01_biography_holonomy_closed_and_modes_reloadable
• New: an ADR-0240 harness PASS report drives a live integrate_biography call with I-01 asserts and a provenance record.
• New (must-reject): a harness report that is NOT all-correct-or-refused must not integrate.

Forbidden actions

No direct vault/pack writes without going through whatever gating the ADR-0240 doc + Shay's design-call answer requires. No relaxing _CLOSURE to make a borderline case pass.

Deliverables

Wiring module (location TBD by operator — likely core/physics/), the new provenance helper, new test file(s).

Operator profile

Genuine identity-substrate design ambiguity (see open question) — strong-reasoning tier, and confirm the mutation-vs-proposal call with Shay before committing to it.
