+Abstaining beats guessing — an honest "I don't know" protects trust, and the TrustLedger credits it.

+This gate is optimizer-agnostic: it reads a ``PlanScore`` (the estimator's plan-time confidence, optionally
+run through a calibration map so the number means P(correct), not a raw score) and returns a verdict. The

+"""Temporal / bi-temporal retrieval — "what changed, and when?" (Whitepaper v3, forthcoming retrieval).
+
+The next retrieval method: a **bi-temporal** store (Graphiti/Zep lineage) where every fact carries two

+
+ • **valid time** (``valid_from`` / ``valid_to``): when the fact is true in the world;
+ • **transaction time** (``recorded_at``): when the system learned it.
+
+That lets the planner answer point-in-time questions the other methods can't: the state *as of* a past
+date, and *as it was known* at a past date (so a late-arriving correction doesn't rewrite history). It is
+densest in conversational corpora (chat/tickets) where facts are constantly revised.
+
+Dependency-free (stdlib + the ``RetrieverPlugin`` seam), so it drops into the planner as one more
+routable capability (``method="temporal"``); the full Graphiti engine can back it as an optional binding.

+"""AgentConsole — a reusable conversational agent that runs entirely on the Context
+Runtime stack.
+
+Every agentic-os app wraps a complex OSS core (ERPNext, Lago, OpenSCAP, CrowdSec, …); the
+dashboards show state but leave users to learn the tool and hunt for the right action.
+``AgentConsole`` is the one chat surface that fixes both: ask *"how do I…?"* or *"explain
+this"* and it answers grounded in the app's guide; ask it to *do* something and it runs a
+tool — always showing its work.
+
+It is deliberately built on our own three planes, not a raw provider SDK:
+
+* **context-runtime** — generation goes through a Context Runtime ``ModelPlugin``
+ (``OpenAICompatibleModel`` when a key is present, else the offline ``StubModel``), so the
+ same cost-tiered ``ModelRequest → ModelResult`` contract and accounting apply.
+* **redevops-rag** — the *"how do I / explain"* path is grounded by retrieval over the app's
+ primer, honouring redevops-rag's ``hybrid_search`` contract. The dependency-free
+ ``PrimerIndex`` here is the offline path; the ``[rag]`` extra swaps in the real reranked
+ index without changing callers.
+* **agent-harness** — actions are dispatched through the harness ``ToolRegistry`` +
+ ``ApprovalPolicy``, so a side-effecting tool is gated and every decision is audited.
+
+One console per app: give it a ``tenant`` name, a ``primer`` (the product knowledge), and a
+list of ``tools`` (each bound to that app's core API). ``respond()`` returns a transparent
+payload the chat panel renders; ``panel_html()`` returns the panel itself.

+"""Online-learning optimizer — Generation 4 (Whitepaper v3).

+seeded with the cost model's estimate as an optimistic prior and refined by measured reward. Selection
+balances exploitation (the best learned plan) against exploration (trying alternatives), and every
+choice records its selection probability so alternatives can be evaluated off-policy — the cheapest
+exploration tier.
+
+Layered exploration (paper's "cheapest form that answers the question"):
+ • Tier 1 — off-policy evaluation: score alternative plans from executions already observed, using the
+ logged selection probabilities (``offpolicy_values``). Zero user-facing latency.
+ • Tier 2 — shadow execution: run a candidate off the serving path (``select(..., shadow=True)`` marks
+ a shadow pick; the caller executes it asynchronously and feeds the reward back via ``learn``).
+ • Tier 3 — live exploration: the ε-greedy branch actually serves an exploratory plan.
+
+Reuses the fleet's ``EpsilonGreedyBandit`` as the shared per-(context, arm) value store, and composes
+with the Phase-0 governance seam: a PolicyProvider still filters the feasible space *before* any
+exploration (you never explore an infeasible plan), and a TrustProvider breaks ties.

+"""Knowledge representations — the planner's first-class decision axis (Whitepaper v4).
+
+Context Runtime does not assume every problem is document retrieval. A request is first
+mapped to the *knowledge representation* that can answer it — a document, a graph of
+relationships, a bi-temporal fact history, an analytical/OLAP cube, code, or media — and
+only then to a concrete ``Retrieval`` method within that representation. Retrieval is one
+specialization; the planner routes across representations without the application changing.
+
+This module holds the (deliberately small, inspectable) mapping from retrieval method →
+representation, so plans, traces and the cost model can reason about *which representation*
+was chosen — not just which method. The heavy engines behind each representation (a hosted
+Graphiti temporal store, an OLAP connector, a real HippoRAG graph) bind at construction time
+via the ``RetrieverPlugin`` seam; this table is only the taxonomy.

+"""Capability Registry — capabilities live in the PLANNER, not the prompt (Whitepaper v3).
+
+The paper's pivotal scaling property: an assistant's abilities (retrieval methods, model tiers,
+reasoners, tools) are registered *out of band*, each with cost/quality priors and the intent buckets
+it serves. The planner selects among them using intent, policy, and cost — the model never sees a tool
+catalog in its context window. "Capability count scales in a registry — which is cheap — rather than
+in the context window, which is not."
+
+This module is the catalog. ``RegistryCandidateGenerator`` (planner/candidates_registry.py) consults it
+to enumerate candidate plans, so adding a capability is a ``register()`` call, not an edit to the rule
+tables or the prompt. ``CapabilityRegistry.from_rules()`` lifts the existing v0.1 rule tables into

+**Source — PubMedQA** (Jin et al., EMNLP 2019, https://github.com/pubmedqa/pubmedqa, MIT):
+1 000 expert-labeled biomedical questions over real PubMed abstract passages, each with gold
+contexts and a long-form answer. Its clinical vocabulary (discharge, statement, balance,

+the **Mixed** model's coverage-routing win (cross-domain noise → 0) visible.
+

+python3 build_corpus.py # → ../../.medical/corpus/*.txt (~3.3k passages) + qa.jsonl

+`build_corpus.py` writes one normalized `.txt` passage per (PMID, abstract section) — the same
+pre-normalized shape the FinanceBench corpus uses, so the control plane ingests it directly
+(mounted RO at `/medical`, tenant `context-runtime-medical`). No PDF/OCR step.

+# Context Runtime — Final Benchmark Report
+
+_Full `examples/` suite run end-to-end on the v3 engine. Every number is produced by a runnable
+script (`PYTHONPATH=. python examples/.py`) — no invented figures._
+
+**Run status: 30 / 30 benchmarks passed** (seeded, deterministic simulations; the consolidated
+headline is cross-checked in the independent Go re-implementation).
+
+**Judge change in this cycle:** the LLM-as-judge default moved from **OpenAI GPT-5.5 → Grok 4.5**
+(xAI, OpenAI-compatible, ~5× cheaper), now a *dedicated* judge endpoint kept separate from the chat
+model (`CR_JUDGE_BASE_URL` / `CR_JUDGE_MODEL` / `CR_JUDGE_API_KEY`, default `grok-4.5`). Note: the
+offline benchmarks below use a *seeded coverage judge* (no live LLM), so their numbers are unaffected
+by the judge model — the judge swap changes the **live** self-learning RAG's cost, not these results.
+
+---
+
+## 1. Headline — v1 → v2, measured in both runtimes (`consolidated_benchmark`)
+
+| Metric | Py v1 | Py v2 | Δ | Go v1 | Go v2 | Δ |
+| --- | --- | --- | --- | --- | --- | --- |
+| Learned-policy precision | 67.6% | 82.2% | ▲ +14.6 pts | 84.6% | 95.9% | ▲ +11.3 pts |
+| Abstention recall (unanswerable caught) | 0.0% | 100.0% | ▲ +100 pts | 0.0% | 100.0% | ▲ +100 pts |
+| False-abstain rate (answerable dropped) | 0.0% | 0.0% | — | 0.0% | 0.0% | — |
+| Expensive-stage depth (passages) | 8.00 | 3.00 | ▼ −62% | 8.00 | 3.00 | ▼ −63% |
+| Precision after the sizer | 37.5% | 100.0% | ▲ +62.5 pts | 37.5% | 100.0% | ▲ +62.5 pts |
+
+_40-seed average; precision headlined at β=0.9 (calibration-trust knob; shipped default 0.5). Go is an
+independent re-implementation on identical methodology — directional parity across languages._
+
+## 2. Calibration sweep (`dspark_calibration_bench`)
+
+Served true-precision, 40 seeds, coverage-biased judge:
+- v1 judge-only (β=0.0): **67.6%** → v2 judge + calibrated relevance: β0.5 **68.9%** (+1.3), β0.7 **74.3%** (+6.7), β0.9 **82.2%** (+14.6).
+- Abstention (P(rel)≥0.5 floor, v1 cannot abstain): sizer off → 8 passages @ 38% precision; sizer on → **3 passages @ 100%** (depth −62%, the pruned tail was the low-relevance one).
+
+## 3. Online adaptation under drift (Gen-4)
+
+- **`online_vs_static_bench`** — best plan drifts A→C at t=200. Post-drift served reward: static **0.20** · online-plain **0.33** · **online-discounted 0.67** (oracle 0.80). Discounting fades stale evidence so the planner tracks the shift.
+- **`online_learning`** — priors say hybrid=0.80/graph=0.55 (static always serves hybrid); production reward returns graph=0.9/hybrid=0.3 → after learning the planner serves **graph**, adapting past the stale estimate (surfaced without re-running it, via off-policy value).
+- **`learning_loop`** — async learning drained 8 events off the serving path → snapshot v1; replica reconciles and switches hybrid→graph with **zero learning on the hot path**.
+
+## 4. Retrieval methods & routing
+
+- **`hop_routing`** — intent-routed: conceptual → hybrid (acc 0.78, $0.06); **multi-hop → graph** (acc 0.88, $0.43), surfacing a bridge doc via the ATP→α-synuclein hop.
+- **`parallel_fusion`** — fan-out wall-clock **5.9× faster** (50.9 ms parallel vs 300.8 ms sequential), then rerank-before-model.
+- **`heterogeneous_shards`** — community/coverage routing cut cross-domain noise **23 → 0 docs** across 8 medical queries while keeping recall **8/8**.
+- **`multimodal_image_search`** — cross-modal text→image: each text query retrieves the right image as top hit (no OCR, no shared terms).
+- **`temporal_retrieval`** — bi-temporal as-of filtering (a record filed 2026-07-15 is correctly invisible to a 2026-06-15 as-of query).
+- **`rag_tuning`** — per-intent optimal config recovered (exact_lookup / incident / conceptual all match the latent best) after 40 observed retrievals.
+
+## 5. Trust & governance (Gen-5)
+
+- **`trust_aware`** — trust folded into plan selection (trust_weight 0.6 → the relied-upon local plan wins); abstention gate: expected accuracy 0.80 clears the 0.7 threshold → **SERVE** (else abstain).
+- **`capability_registry`, `explain`, `chat_memory`** — capability gating, EXPLAIN-ANALYZE traces, and conversational memory all green.
+
+## 6. Fleet / tenants (`fleet_tenants` + per-app demos)
+
+**17 tenants**, one pattern: each module = one goal, one metric, a learned *cheapest-sufficient source*
+policy — replacing hand-wired controllers with one data-driven Context Runtime tenant pattern. The
+per-app tenant demos all ran green: `agentic_billing, agentic_books, agentic_compliance,
+agentic_support, control_tower, market_radar, growth_engine, social_autopilot, outreach_engine,
+outreach_pipeline, incident_review, soc_triage, sidekick_learning, vibexgen_learning`.
+
+## Full run table
+
+All 30 scripts exited 0. Slowest: `consolidated_benchmark` (14s, runs the Go twin), `dspark_calibration_bench` (12s). One pre-existing example bug fixed this cycle: `fleet_tenants` was missing an `outreach` probe (added).
