 ### Added

+- **Salesforce ingestor** (#1240) by @Sameer6305
+  - New `SalesforceConnector` / `SalesforceData` / `SalesforceIngestor` (`semantica.ingest`, lazy export), following the same Connector + Data + Ingestor pattern already used for Snowflake/Databricks/SAP
+  - Auth covers both landscapes Salesforce actually uses: username + password + security token (SOAP login), session_id + instance_url (reusing an existing session), and username + consumer_key + private key (JWT Bearer); production and sandbox are selected via `domain`, and credentials can come from environment variables. Credential material is never intentionally written to logs, exceptions, or `repr()`
+  - `ingest_sobject()`, `ingest_query()`, `list_sobjects()`, `get_sobject_schema()`, `export_as_documents()` against standard sObjects, custom objects (`__c`), custom metadata (`__mdt`), platform events (`__e`), namespaced objects, and relationship-field traversal (e.g. `Owner.Name`); pagination follows `nextRecordsUrl`/`query_more()` and stops once a caller's `limit` is satisfied
+  - New `pip install semantica[db-salesforce]` extra (`simple-salesforce>=1.12.0`)
+  - New `tests/test_salesforce_ingestor.py`
+  - Docs: `docs/integrations/salesforce.md`
+
 - **`ErasureCoordinator` completes the erasure workflow `purge_node()` only starts — the graph node was removed while the same content survived verbatim in `AgentMemory` and as an embedding** (closes #1018) by @pravit-amp
  - New `semantica/context/erasure.py`, exporting `ErasureCoordinator` and `ErasureReceipt` from `semantica.context`. `purge_node()`/`purge_edge()` (#957) are graph-scope by design and their changelog entry documents this gap explicitly; the changelog also names GDPR Article 17 as the motivation, and an Article 17 erasure that removes the node while the content stays retrievable by similarity search is not an erasure — it is worse than not offering one, because `purge_node()` returns `True` and writes a tombstone attesting the content is gone
  - The coordinator **composes** the existing public APIs — nothing in `context_graph.py` or `agent_memory.py` changes behaviorally, and `ContextGraph` keeps its documented graph-scope contract rather than acquiring references to `AgentMemory`/`vector_store` that would invert the dependency
@@ -151,6 +159,19 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
  - **Also fixed, on the JSON-LD paths**: the first fix covered the Turtle, N-Triples and RDF/XML serializers, and left both JSON-LD writers interpolating the entity's own text into `f"semantica:entity/{text}"` and the endpoints into `f"semantica:rel/{source}_{target}"`. Three consequences, all live in 0.6.5: an entity whose text contained a space produced an invalid IRI, and a JSON-LD parser dropped that node in full rather than reporting it, so the entity disappeared from the export; every relationship carrying `source`/`target` rather than `source_id`/`target_id` minted the identical `semantica:rel/_`, collapsing all of them onto one node whose types and endpoints merged; and the JSON-LD `@id` disagreed with the Turtle IRI for the same entity, so the two serializations of one knowledge graph were two different graphs. Both JSON-LD writers now use `mint_entity_iri`/`mint_relationship_iri`, and `JSONExporter.export_entities`/`export_relationships` declare the `semantica` prefix their `@context` was already writing `semantica:entities` against — without it a processor reads that as an IRI in the scheme `semantica`, which is the original #1101 defect on a third path
  - `tests/export/test_jsonld_iri_minting.py` parses each export with a real JSON-LD processor and asserts the entity survives, the relationships stay distinct, no term expands into the `semantica` scheme, and the JSON-LD `@id` equals the Turtle IRI
  - 236 export and ontology tests pass
+- **`semantica.evals` runner gains per-metric objectives** (#1091)
+  - `evaluate()` now accepts `config={"<evaluator>": {"objective": {"direction": "maximize"|"minimize", "threshold": X}}}` to override the evaluator's default pass verdict with a threshold; `{"objective": {"expect": bool}}` expresses a Boolean expectation
+  - `minimize` requires a `threshold` — omitting it or setting it to `None` raises `ValueError`; `maximize` without a threshold is a no-op (the evaluator's own verdict stands); `expect` cannot be combined with `direction`/`threshold`; invalid config raises `ValueError` before any evaluator runs
+  - Error metrics are never affected by objectives (error wins over fail)
+  - Backward compatible: no `objective` key → existing behavior unchanged
+  - New tests in `tests/evals/test_runner.py::TestObjective`
+- **`semantica.evals` is now a fully implemented evaluation module** (was a "Coming Soon" stub in the package layout)
+  - `evaluate(cases, evaluators, config=None, target_fn=None)` runner with per-case `pass`/`fail`/`error` status and an aggregate `pass_rate`, using a registry of named evaluators (`list_evaluators()`)
+  - 10 built-in evaluators: `exact_match`, `regex_match`, `numeric_range`, `temporal_range`, `length_range`, `keyword_check`, `levenshtein` (edit-distance similarity), `rouge` (in-house token F1, no new dependencies), `llm_as_judge` (lazy: caller-supplied `judge_fn`), and `decision_scores` (composite over `semantica.context.Decision`)
+  - `decision_scores` validates field-level (expected outcome, confidence bounds, non-empty maker/reasoning/scenario) and governance-level (provenance record presence; opt-in `PolicyEngine.check_compliance`) checks, coercing dict inputs via `Decision(**actual)` and never crashing on malformed input; an interface slot for causal-chain/embedding checks is reserved and raises `NotImplementedError` (V2)
+  - `__version__` is `0.1.0`, and the module ships a usage guide at `semantica/evals/usage.md` with worked import/run/interpret examples
+  - `semantica.evals` is reachable through the root package lazy module proxy (`semantica.evals`)
+  - 99 unit tests in `tests/evals/` covering every evaluator, registry errors, runner aggregation, decision coercion, and per-metric objectives; `python -m pytest tests/evals -q` → 99 passed

 - **First-class CrewAI integration** (#988, closes #962) by @Shindevrp
  - New `pip install semantica[crewai]` extra (`crewai>=0.80.0`) — crewai core provides `BaseTool`/`BaseKnowledgeSource`, so `crewai-tools` is intentionally not included, and the extra is intentionally **not** part of the `all` bundle: crewai hard-requires `chromadb~=1.1.0`, which is affected by the unpatched pre-auth code-injection CVE-2026-45829 (see `integrations/crewai/README.md`)

 title: "Evals Module"

+description: "Score decision records, audit trails, and reasoning output with deterministic and model-backed evaluators plus a small run harness."
 icon: "chart-line"
 ---

-**`semantica.evals`** is planned as a comprehensive evaluation framework for measuring **extraction accuracy, graph quality, and pipeline performance**.
+`semantica.evals` measures the quality of decision intelligence outputs. It takes
+the decisions, audit trails, and reasoning text your pipeline produces and scores
+them against expectations you define, returning a structured summary you can log,
+assert on in tests, or track across runs.

-<Warning>
-  **`semantica.evals` is not yet implemented.** The module is a placeholder with `__all__ = []`. No classes or functions are available for import. This page describes the planned API only.
-</Warning>
+- A registry of named evaluators, from exact string matching to ROUGE overlap and
+  LLM-as-judge
+- `decision_scores`, a composite evaluator for `Decision` objects that checks
+  outcome, confidence bounds, required fields, provenance, and (optionally)
+  policy compliance
+- A `evaluate()` runner that applies several evaluators to a list of cases and
+  aggregates pass / fail / error counts
+- Per-evaluator **objectives** that let you override an evaluator's built-in
+  verdict at the run level

-## Planned Features
+<Note>
+  The module is versioned separately from the package: `semantica.evals.__version__`
+  is `"0.1.0"`. The public surface described here is stable, but expect additive
+  changes (new evaluators, new objective options) before it reaches 1.0.
+</Note>

-When released, `semantica.evals` will provide:
+## Public API

-| Planned Class | Role |
-| :--- | :--- |
-| `KGEvaluator` | Completeness, consistency, schema compliance, coverage, and orphan node detection |
-| `ExtractionEvaluator` | NER precision / recall / F1 and relation extraction metrics against gold datasets |
-| `PipelineBenchmark` | Throughput (docs/sec), per-step latency, peak memory, and error rate |
-| `RegressionTracker` | Record runs and compare metrics across commits or config changes |
-| `EvalReport` | Structured report: `{scores, regressions, recommendations}` |
-| `DeduplicationEvaluator` | Merge precision, false positive / false negative rates |
-| `ReasoningEvaluator` | Inference accuracy, rule coverage, and derivation depth |
-
-## Current Workaround
-
-Until `semantica.evals` ships, use `semantica.ontology.OntologyEvaluator` for ontology quality metrics:
+| Name | Kind | Role |
+| :--- | :--- | :--- |
+| `evaluate(cases, evaluators, config=None, target_fn=None)` | function | Run named evaluators over each case, return an `EvalSummary` |
+| `list_evaluators()` | function | Sorted names of every registered evaluator |
+| `get_evaluator(name)` | function | Look up a single evaluator function by name |
+| `EvalMetric` | dataclass (frozen) | One evaluator's result: `score`, `passed`, `meta` |
+| `CaseResult` | namedtuple | One case's result: `case_id`, `status`, `metrics`, `details` |
+| `EvalSummary` | dataclass | Aggregate across cases: `total`, `passed`, `failed`, `errors`, `pass_rate`, `cases` |

 ```python
-from semantica.ontology import OntologyEvaluator
-
-evaluator = OntologyEvaluator()
-
-# evaluate_ontology takes the ontology dict only
-result = evaluator.evaluate_ontology(ontology)
-
-print("Coverage:    ", result.coverage_score)

-print("Relation coverage: ", report["relation_completeness"]["relation_coverage"])

+## Built-in evaluators

-| Field | Type | Description |
-| :----- | :---- | :----------- |
-| `coverage_score` | `float` | Fraction of competency questions answerable by the ontology |
-| `completeness_score` | `float` | Average of class and property completeness scores |
-| `gaps` | `List[str]` | Identified gaps in coverage |
-| `suggestions` | `List[str]` | Improvement suggestions |
-| `metrics` | `dict` | Detailed sub-metrics |
+Every evaluator is a plain function `fn(actual, expected, config=None) -> EvalMetric`
+registered under a stable name. `list_evaluators()` returns the current set:

- [Semantic Extract](semantic_extract) — Extraction module.
- [Knowledge Graph](kg) — Graph quality assessment.
- [Pipeline](pipeline) — Pipeline performance metrics.
- [Ontology Evaluator](ontology) — Available now for ontology quality metrics.
+```python
+>>> list_evaluators()
+['decision_scores', 'exact_match', 'keyword_check', 'length_range',
+ 'levenshtein', 'llm_as_judge', 'numeric_range', 'regex_match', 'rouge',
+ 'temporal_range']
+```
+
+| Name | Passes when | Relevant `config` keys |
+| :--- | :--- | :--- |
+| `exact_match` | `actual == expected` | none |
+| `regex_match` | `re.search(expected, actual)` matches | none |
+| `keyword_check` | every required term appears in `actual` (word-boundary) | `required` (falls back to `expected`) |
+| `numeric_range` | `min <= actual <= max` | `min`, `max` (both required) |
+| `temporal_range` | ISO datetime `actual` falls in `[min, max]` | `min`, `max` as ISO strings (both required) |
+| `length_range` | `min <= len(actual) <= max` | `min` (default 0), `max` (required) |
+| `levenshtein` | normalized similarity `>= threshold` | `threshold` (default 0.8) |
+| `rouge` | ROUGE-1 F1 `> 0` and `>= threshold` | `threshold` (default 0.0) |
+| `llm_as_judge` | caller-supplied `judge_fn(actual, expected)` returns truthy | `judge_fn` (required callable) |
+| `decision_scores` | all configured sub-checks on a `Decision` pass | see below |
+
+An evaluator that cannot run (bad regex, unparseable datetime, no `judge_fn`) returns an
+`EvalMetric` with an `"error"` key in `meta` rather than raising. Evaluators that
+require numeric bounds (`numeric_range`, `length_range`) instead return a failing
+metric with a `"reason"` key when the bound is missing — they do not raise and do
+not set `"error"`.
+
+### `decision_scores`
+
+`decision_scores` accepts a `Decision` (from `semantica.context.decision_models`)
+or its dict form and runs a set of field-level and governance checks. The score is
+the fraction of checks that passed; `passed` is `True` only when all of them did.
+
+| Sub-check | Controlled by |
+| :--- | :--- |
+| Outcome matches | `expected_outcome` in config, or the case's `expected`; **skipped** when neither is set |
+| Confidence in range | `min_confidence` (default 0.0), `max_confidence` (default 1.0); always run |
+| `decision_maker`, `reasoning`, `scenario` non-empty | always run |
+| Provenance present in metadata | `provenance_key` (default `"provenance"`); always run |
+| Policy compliance | `policy_engine` and `policy_id` both set; skipped otherwise |
+
+Passing `causal_chain_exists` in config raises `NotImplementedError`. That key is a
+reserved slot for a future release.
+
+## Running an evaluation
+
+`evaluate()` takes a list of cases and a list of evaluator names. A case is either
+a `(expected, actual)` tuple or a dict:
+
+```python
+{
+    "id": "loan-001",          # optional, generated if absent
+    "expected": ...,           # optional; some evaluators read it, some don't
+    "actual": ...,             # the value under test
+    "config": {...},           # optional, per-evaluator settings for this case
+    "target_fn": callable,     # optional, called with the case to produce `actual`
+}
+```
+
+If `actual` is missing, the runner calls the case's `target_fn` (or the
+`target_fn` passed to `evaluate()`) to produce it. Per-case `config` is deep-merged
+over the top-level `config`, so a case can override one evaluator's settings
+without discarding the rest.
+
+```python
+from datetime import datetime

+                "expected_outcome": "approve",
+                "min_confidence": 0.7,

+        },
+    },
+]
+
+summary = evaluate(cases, ["decision_scores"])
+print(summary.pass_rate)   # 1.0
+```
+
+Evaluators run independently per case. If one raises, that case's `status` becomes
+`"error"` and the exception text is captured in the metric's `meta`; the rest of
+the run continues.
+
+## Objectives
+
+By default each evaluator decides its own pass / fail. An **objective** overrides
+that verdict at the run level, keyed by evaluator name under `config`:
+
+```python
+# Raise levenshtein's bar from its default 0.8 to 0.9
+evaluate(
+    [("apple", "aple")],
+    evaluators=["levenshtein"],
+    config={"levenshtein": {"objective": {"direction": "maximize", "threshold": 0.9}}},
+)
+
+# Lower is better
+evaluate(
+    [("night", "nacht")],
+    evaluators=["levenshtein"],
+    config={"levenshtein": {"objective": {"direction": "minimize", "threshold": 0.5}}},
+)
+
+# Expect the metric NOT to match
+evaluate(
+    [("ok", "ok")],
+    evaluators=["exact_match"],
+    config={"exact_match": {"objective": {"expect": False}}},
+)
+```
+
+Rules:
+
+- `maximize` with `threshold`: pass iff `score >= threshold`. `maximize` with no
+  threshold is a no-op and the evaluator's own verdict stands.
+- `minimize` with `threshold`: pass iff `score <= threshold`. `minimize`
+  **requires** a threshold; omitting it raises `ValueError`.
+- `expect` (`True` / `False`): pass iff `bool(score)` equals it. Cannot be combined
+  with `direction` or `threshold`, and must be a real boolean.
+- A metric that already carries an `"error"` in its `meta` is unaffected by any
+  objective.
+- Invalid objective config is validated for every case before any evaluator runs,
+  so a bad objective fails the whole run up front rather than partway through.
+
+## Reading the summary
+
+```python
+summary = evaluate(cases, ["decision_scores"])
+
+summary.total, summary.passed, summary.failed, summary.errors
+summary.pass_rate    # passed / total, or 1.0 for an empty case list
+
+for case in summary.cases:
+    print(case.case_id, case.status)          # status: "pass" | "fail" | "error"
+    for name, metric in case.metrics.items():
+        print(name, metric.score, metric.passed)
+        print(metric.meta.get("reasons", {}))  # per-sub-check failure reasons
+```
+
+`EvalMetric` is frozen (`score: float`, `passed: bool`, `meta: dict`). `CaseResult`
+is a namedtuple, and `EvalSummary` is a plain dataclass, so all three are
+straightforward to serialize for logging or regression tracking.
+
+## Notes
+
+- `llm_as_judge` needs `config["judge_fn"]`, a callable
+  `judge_fn(actual, expected) -> bool` you supply. No LLM backend is imported
+  unless you pass one in.
+- `decision_scores` governance checks are opt-in: policy compliance is only
+  evaluated when both `policy_engine` and `policy_id` are present.

+# Objective Layer for semantica.evals Runner — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add per-metric objective support (direction + threshold, or Boolean expectation) to the `evaluate()` runner, overriding evaluator default pass verdicts, backward-compatible when no objective is configured.
+
+**Architecture:** The runner already iterates evaluators and computes per-case status. Objectives are read from `config["<name>"]["objective"]`, validated up front, and applied to each returned metric's `passed` field (and `details`) before aggregation. Error metrics always win over objectives.
+
+**Tech Stack:** Python 3.8+, stdlib only (typing, dataclasses). pytest for tests.
+
+## Global Constraints
+
+- Python >= 3.8: use `typing.Dict/List/Optional/Union`, never builtin generics or `|`.
+- Zero new dependencies.
+- Do not change the `EvalMetric` shape, the `evaluate()` signature, or the evaluator function signature.
+- Existing behavior with no `objective` configured must be byte-for-byte unchanged (all 62 existing tests keep passing).
+- Error metrics (`meta` contains `"error"`) always classify the case as `error`, regardless of objective.
+- Config errors are programmer errors: raise `ValueError` from `evaluate()` before any evaluator runs (fail-fast).
+- Tests go in `tests/evals/`, pytest class style, no new files outside the listed paths.
+
+---
+
+### Task 1: Objective parsing, validation, and re-decision in the runner
+
+**Files:**
+- Modify: `semantica/evals/runner.py`
+- Test: `tests/evals/test_runner.py`
+
+**Interfaces:**
+- Consumes: `EvalMetric` from `.types` (fields: `score`, `passed`, `meta`); `evaluate(cases, evaluators, config=None, target_fn=None)` existing signature.
+- Produces: private helpers `_parse_objective(name, eval_config) -> Optional[Dict]` (returns `None` when no objective configured, raises `ValueError` on invalid config) and `_apply_objective(metric, objective) -> bool` (returns the re-decided `passed`). Public `evaluate()` behavior extended as specified.
+
+- [ ] **Step 1: Write the failing tests**
+
+Append a new test class to `tests/evals/test_runner.py`:

+- [ ] **Step 2: Run tests to verify they fail**
+
+Run: `python3 -m pytest tests/evals/test_runner.py -q`
+Expected: the new `TestObjective` tests fail (objective config ignored → `exact_match` passes under `expect:false` etc.); the pre-existing tests in the file still pass.
+
+- [ ] **Step 3: Implement objective parsing, validation, and re-decision**
+
+In `semantica/evals/runner.py`, add two helpers before `evaluate` and wire them into the evaluator loop.
+
+```python
+def _parse_objective(name, eval_config):
+    """Return the validated objective dict, or None when not configured.
+
+    Raises ValueError for invalid configurations (programmer error).
+    """
+    objective = (eval_config or {}).get("objective")
+    if objective is None:
+        return None
+    direction = objective.get("direction")
+    threshold = objective.get("threshold")
+    expect = objective.get("expect")
+
+    if expect is not None:
+        if direction is not None or threshold is not None:
+            raise ValueError(
+                f"objective for '{name}': 'expect' cannot be combined with "
+                "'direction' or 'threshold'"
+            )
+        return {"expect": bool(expect)}
+    if direction == "minimize":
+        if threshold is None:
+            raise ValueError(
+                f"objective for '{name}': 'minimize' requires a 'threshold'"
+            )
+        return {"direction": "minimize", "threshold": float(threshold)}
+    if direction == "maximize":
+        if threshold is None:
+            # no bar to re-decide against; treat as absent (evaluator default stands)
+            return None
+        return {"direction": "maximize", "threshold": float(threshold)}
+    raise ValueError(
+        f"objective for '{name}': 'direction' must be 'maximize' or 'minimize' "
+        f"(got {direction!r})"
+    )
+
+
+def _apply_objective(metric, objective):
+    """Return the objective-adjusted pass verdict for a non-error metric."""
+    if "expect" in objective:
+        return bool(metric.score) == objective["expect"]
+    if objective["direction"] == "minimize":
+        return metric.score <= objective["threshold"]
+    return metric.score >= objective["threshold"]
+```
+
+Then modify the evaluator loop in `evaluate()` so the parsed objective is computed once per case (outside the evaluator loop, since it only depends on merged config), and applied inside the loop:
+
+```python
+        objective_by_name = {
+            name: _parse_objective(name, merged.get(name) or {})
+            for name in evaluators
+        }
+        metrics: Dict[str, EvalMetric] = {}
+        details: Dict[str, Any] = {}
+        failed, errored = False, False
+        for name in evaluators:
+            eval_config = merged.get(name) or {}
+            try:
+                metric = get_evaluator(name)(actual, expected, config=eval_config)
+                objective = objective_by_name.get(name)
+                if objective is not None and "error" not in metric.meta:
+                    metric = EvalMetric(metric.score, _apply_objective(metric, objective), metric.meta)
+                metrics[name] = metric
+                if "error" in metric.meta:
+                    errored = True
+                    details[name] = metric.meta
+                elif not metric.passed:
+                    failed = True
+                    details[name] = metric.meta
+            except Exception as exc:  # noqa: BLE001
+                errored = True
+                metrics[name] = EvalMetric(0.0, False, {"error": str(exc)})
+                details[name] = {"error": str(exc)}
+```
+
+Note: `objective_by_name` is computed once per case (it depends only on merged config), so invalid config raises `ValueError` at the first case — satisfying the fail-fast requirement. `EvalMetric` is a frozen dataclass, so the re-verdict constructs a new instance preserving score/meta.

+## Set per-evaluator objectives
+
+By default each evaluator decides its own pass/fail. To override that
+verdict at the run level, configure an **objective** per evaluator name:
+
+```python
+from semantica.evals import evaluate
+
+# Require a minimum similarity (default direction is maximize):
+evaluate(
+    [("apple", "aple")],
+    evaluators=["levenshtein"],
+    config={"levenshtein": {"objective": {"direction": "maximize", "threshold": 0.7}}},
+)
+
+# Lower is better — override the direction:
+evaluate(
+    [("night", "nacht")],
+    evaluators=["levenshtein"],
+    config={"levenshtein": {"objective": {"direction": "minimize", "threshold": 0.5}}},
+)

+# Boolean expectation on a 0/1 metric:
+evaluate(
+    [("ok", "ok")],
+    evaluators=["exact_match"],
+    config={"exact_match": {"objective": {"expect": False}}},
+)
+```
+
+Rules:
+
+- `maximize` + `threshold`: pass iff `score >= threshold`. `maximize` without
+  a threshold is a no-op (the evaluator's own verdict stands).
+- `minimize` + `threshold`: pass iff `score <= threshold`. `minimize`
+  **requires** a threshold — omitting it raises `ValueError`.
+- `expect` (`true`/`false`): pass iff `bool(score)` matches; cannot be
+  combined with `direction`/`threshold`.
+- A metric whose `meta` contains `"error"` is always an error, never affected
+  by an objective.
+- Invalid objective config raises `ValueError` before any evaluator runs.
+```
+
+- [ ] **Step 2: Add CHANGELOG entry**
+
+Under `## [Unreleased]` → `### Added`, insert a new bullet at the top (before the `semantica.evals` module entry), following existing style:
+
+```markdown
+- **`semantica.evals` runner gains per-metric objectives** (#1091)
+  - `evaluate()` now accepts `config={"<evaluator>": {"objective": {"direction": "maximize"|"minimize", "threshold": X}}}` to override the evaluator's default pass verdict with a threshold; `{"objective": {"expect": bool}}` expresses a Boolean expectation
+  - `minimize` requires a `threshold`; `maximize` without one is a no-op; `expect` cannot be combined with `direction`/`threshold`; invalid config raises `ValueError` before any evaluator runs
+  - Error metrics are never affected by objectives (error wins over fail)
+  - Backward compatible: no `objective` key → existing behavior unchanged
+  - New tests in `tests/evals/test_runner.py::TestObjective`
+```
+
+- [ ] **Step 3: Verify docs examples run**
+
+Run the three examples from Step 1 as a Python script (import `evaluate`, run each snippet) to confirm they don't raise unexpectedly. No test output assertion needed beyond "no exception" and sensible status values.

+# Design: Objective layer for `semantica.evals` runner
+
+**Date:** 2026-08-19
+**Issue:** semantica-agi/semantica#1091 (assigned to pkupt)
+**Base:** PR #1090 (`semantica.evals` module)
+
+## 1. Problem
+
+`semantica.evals` runs named evaluators and aggregates per-case pass/fail, but the pass judgement is hard-coded inside each evaluator — a higher score always means "better". There is no way to express an evaluation objective at the run level:
+
+- apply a threshold the evaluator does not encode (e.g. "F1 must be ≥ 0.7");
+- reverse the direction (e.g. "lower edit distance is better");
+- express a Boolean expectation (e.g. "this metric should be `false`").
+
+This blocks the domain-specific benchmark harnesses `docs/community-projects.md` says `semantica.evals` supports. Palantir AIP Evals models exactly this: each metric has an **objective** (Boolean expected value, or numeric `maximize`/`minimize` direction with an optional threshold), and a test case passes when **all** its metrics meet their objectives.
+
+## 2. Scope
+
+In scope:
+
+- A per-metric objective configuration consumed by the `evaluate()` runner.
+- Runner-level pass/fail re-decision for numeric scores and Boolean metrics.
+- Backward-compatible behavior when no objective is configured.
+- Tests and docs.
+
+Out of scope:
+
+- Changing the evaluator signature or the `EvalMetric` shape.
+- Multi-iteration test cases (AIP Evals has them; Semantica's runner is single-iteration per case).
+- Objective-aware aggregation beyond per-case `pass`/`fail` (existing `pass_rate` semantics are kept).
+
+## 3. Design
+
+### 3.1 Configuration surface
+
+Objective is configured per evaluator inside the runner's `config`, under the evaluator name:
+
+```python
+config = {
+    "<evaluator_name>": {
+        "objective": {
+            "direction": "maximize" | "minimize",
+            "threshold": <float>,   # optional
+        }
+    }
+}
+```
+
+Boolean-form objective (shorthand): for metrics whose score is Boolean-like (0.0/1.0) or for semantic clarity, `{"objective": {"expect": true}}` / `{"objective": {"expect": false}}` is also supported.
+
+### 3.2 Evaluation semantics
+
+For each metric produced by an evaluator during a case run, if an objective exists for that evaluator name, the runner recomputes the metric's pass verdict:
+
+- **maximize**: pass iff `score >= threshold`. If no `threshold` is given, the objective is treated as absent (evaluator's own verdict stands) — see 3.4 rule 2.
+- **minimize**: pass iff `score <= threshold` (threshold required, see 3.4 rule 1).
+- **expect**: pass iff `bool(score)` equals `expect` (for Boolean-style metrics).
+
+When an objective is present, the runner **overrides** `metric.passed` with the objective verdict. When absent, `metric.passed` is used unchanged (existing behavior).
+
+The `objective` key is a **reserved runner-level key**: it is consumed by the runner and is passed through to the evaluator function inside `eval_config` (evaluators already ignore unknown config keys via `cfg.get(...)`, so this is harmless); evaluators must not rely on it. The runner re-decision happens on the metric the evaluator returns, so no evaluator change is required.
+
+### 3.3 Interaction with errors
+
+An `EvalMetric` whose `meta` contains `"error"` remains classified as an error regardless of objective (error wins over fail, per the existing contract). Objectives only affect non-error metrics.
+
+### 3.4 Ambiguity rules (explicit decisions)
+
+1. **`minimize` without `threshold`** is rejected at config-validation time with a clear error (`ValueError`), because "lowest is best" has no absolute pass bar without a threshold. (AIP Evals allows direction-only; we require threshold to keep pass/fail well-defined.) — *Chosen for determinism; revisit if a use case demands direction-only minimize.*
+2. **`maximize` without `threshold`** behaves like no objective (pass iff evaluator's own `passed`), because the evaluator's default is already "higher is better".
+3. **`expect` with a numeric `direction`/`threshold`** is a config error (`ValueError`): pick one form.
+4. **Objective on a metric that errors** → the error wins (3.3), objective ignored.
+
+### 3.5 Aggregation
+
+Unchanged:
+
+- Case `status`: `"error"` if any metric errored, else `"fail"` if any failed, else `"pass"`.
+- `pass_rate` = passed / total (1.0 on empty).
+- `metrics` dict holds the (possibly re-verdict'd) `EvalMetric`; the re-verdict is observable via `metric.passed`.
+- `details[name]` is populated when a metric ends up failed **after** objective re-decision (i.e. objective-failed metrics appear in `details`; metrics that pass under objective are not recorded there). This mirrors the existing "record failures in details" behavior applied to the final verdict.
+
+### 3.6 Files
+
+- `semantica/evals/runner.py` — add objective parsing/validation and re-decision inside the evaluator loop.
+- `tests/evals/test_runner.py` — new test class(es) for objective semantics.
+- `semantica/evals/usage.md` — document the objective config and examples.
+- `CHANGELOG.md` — `[Unreleased]` entry.
+
+No new dependencies; Python ≥ 3.8 (stdlib `typing`).
+
+## 4. Error handling
+
+- Invalid objective config (`direction` not in {maximize, minimize}, both `expect` and `direction`, `minimize` without threshold, non-numeric threshold) → `ValueError` raised at runner config parse, before any evaluator runs. Deterministic, fail-fast.
+- These are programmer errors, not per-case data errors — no per-case `error` status involved.
+
+## 5. Testing
+
+New tests in `tests/evals/test_runner.py`:
+
+1. maximize + threshold: score ≥ threshold → pass; below → fail.
+2. minimize + threshold: score ≤ threshold → pass; above → fail (e.g. levenshtein on a close pair).
+3. minimize without threshold → `ValueError`.
+4. expect=true / expect=false on a Boolean metric (exact_match) — pass/fail per expectation.
+5. no objective → existing behavior unchanged (evaluator's own verdict).
+6. objective + error metric → error wins (status=error, not fail).
+7. config error (bad direction) → `ValueError` raised by `evaluate()`.
+8. objective turns a passing metric into failing → `details` records it; case status becomes fail.
+9. backward-compat: all existing 62 tests keep passing.
+
+## 6. Compatibility
+
+- Public API (`evaluate`, `list_evaluators`, `get_evaluator`, types) unchanged in signature.
+- `EvalMetric` shape unchanged (score, passed, meta) — only `passed` may be recomputed by the runner.
+- Existing configs (no `objective` key) behave identically.

+# Semantica Evals — Usage
+
+The evals module measures decision intelligence outputs: decision records,
+audit trails, and reasoning output — with deterministic and model-backed
+evaluators plus a small runner.
+
+## Import
+
+```python
+import semantica.evals as evals          # through the root lazy proxy
+from semantica.evals import evaluate, list_evaluators
+```
+
+## Discover evaluators
+
+```python
+>>> evals.list_evaluators()
+['decision_scores', 'exact_match', 'keyword_check', 'length_range',
+ 'levenshtein', 'llm_as_judge', 'numeric_range', 'regex_match', 'rouge',
+ 'temporal_range']
+```
+
+`list_evaluators` returns every name registered by importing the package —
+the import wiring runs each evaluator module's `register()` side effects.
+
+## Run the runner over decision records
+
+`evaluate(cases, evaluators, config=None)` accepts a list of cases; each case is
+a dict with `expected`, `actual`, optional `config`, and optional `id`. The
+`actual` can be a finished `Decision` object or its dict form.
+
+```python
+from datetime import datetime
+from semantica.context.decision_models import Decision
+from semantica.evals import evaluate
+
+decision = Decision(
+    decision_id="d-1",
+    category="loan",
+    scenario="loan-request",
+    reasoning="vetted by policy",
+    outcome="approve",
+    confidence=0.87,
+    timestamp=datetime.now(),
+    decision_maker="approver-a",
+    metadata={"provenance": "workflow:loan/v3"},
+)
+
+cases = [
+    {
+        "id": "loan-001",
+        "actual": decision,
+        "config": {
+            "decision_scores": {
+                "expected_outcome": "approve",
+                "min_confidence": 0.7,
+            }
+        },
+    },
+    {
+        "id": "loan-002",
+        "actual": {
+            "decision_id": "d-2",
+            "category": "loan",
+            "scenario": "loan-request",
+            "reasoning": "auto",
+            "outcome": "reject",
+            "confidence": 0.9,
+            "timestamp": datetime.now().isoformat(),
+            "decision_maker": "system",
+            "metadata": {},
+        },
+        "config": {
+            "decision_scores": {
+                "expected_outcome": "approve",
+                "min_confidence": 0.7,
+            }
+        },
+    },
+]
+
+summary = evaluate(cases, ["decision_scores"])
+```
+
+`evaluate` also runs high-level names like `exact_match`, `keyword_check`, or
+`llm_as_judge`; per-case or top-level `config` may carry per-evaluator settings
+(e.g. `config={"exact_match": {...}}`).
+
+## Set per-evaluator objectives
+
+By default each evaluator decides its own pass/fail. To override that
+verdict at the run level, configure an **objective** per evaluator name:
+
+```python
+from semantica.evals import evaluate
+
+# Require a minimum similarity (levenshtein's default bar is >= 0.8; here we set 0.7):
+evaluate(
+    [("apple", "aple")],
+    evaluators=["levenshtein"],
+    config={"levenshtein": {"objective": {"direction": "maximize", "threshold": 0.7}}},
+)
+
+# Lower is better — override the direction:
+evaluate(
+    [("night", "nacht")],
+    evaluators=["levenshtein"],
+    config={"levenshtein": {"objective": {"direction": "minimize", "threshold": 0.7}}},
+)
+
+# Boolean expectation — the metric matches (score 1), but we expect it not to:
+evaluate(
+    [("ok", "ok")],
+    evaluators=["exact_match"],
+    config={"exact_match": {"objective": {"expect": False}}},
+)
+```
+
+Rules:
+
+- `maximize` + `threshold`: pass iff `score >= threshold`. `maximize` without
+  a threshold is a no-op (the evaluator's own verdict stands).
+- `minimize` + `threshold`: pass iff `score <= threshold`. `minimize`
+  **requires** a threshold — omitting it or setting it to `None` raises
+  `ValueError`.
+- `expect` (`true`/`false`): pass iff `bool(score)` matches; cannot be
+  combined with `direction`/`threshold`. `expect` must be a real boolean
+  (a string like `"false"` is rejected).
+- A metric whose `meta` contains `"error"` is always an error, never affected
+  by an objective.
+- Invalid objective config (non-dict objective, bad `direction`, non-bool
+  `expect`, missing `minimize` threshold) raises `ValueError` before any
+  evaluator runs.
+
+## Interpret the summary
+
+```python
+>>> summary.total, summary.passed, summary.failed, summary.errors
+(2, 1, 1, 0)
+>>> summary.pass_rate
+0.5
+
+>>> for case in summary.cases:
+...     print(case.case_id, case.status)
+...     for name, metric in case.metrics.items():
+...         print("  ", name, metric.score, metric.passed)
+...         print("    ", metric.meta.get("reasons"))
+loan-001 pass
+   decision_scores 1.0 True
+    {}
+loan-002 fail
+   decision_scores 0.667 False
+    {'decision_outcome': "expected 'approve', got 'reject'",
+     'provenance': 'no provenance record found in metadata'}
+```
+
+`EvalSummary` fields:
+
+- `total` / `passed` / `failed` / `errors` — case counts by status.
+- `pass_rate` — `passed / total` (1.0 on an empty case list).
+- `cases` — one `CaseResult` per input case: `case_id`, `status`
+  (`pass` | `fail` | `error`), `metrics` (name → `EvalMetric` with `score`,
+  `passed`, `meta`), and `details`.
+
+Evaluator failures do not crash the run; they surface as `status="error"` on
+the affected case with the exception text captured in the metric meta.
+
+## Notes
+
+- **`llm_as_judge` needs `config["judge_fn"]`**: a callable
+  `judge_fn(actual, expected) -> bool` supplied by the caller. Without it the
+  evaluator fails with `config['judge_fn'] required`.
+- **`decision_scores` governance checks are opt-in**: policy compliance is only
+  evaluated when both `config["policy_engine"]` and `config["policy_id"]` are
+  provided; otherwise those checks are skipped. The reserved
+  `causal_chain_exists` slot is not yet implemented.
