docs: update tagline to context/semantic layer for high-stakes domains

Replace "The Accountability and Context Layer for AI" with "The
Context and Semantic Layer for AI in High-Stakes Domains" across
docs.json (description, og:title) and index.md (frontmatter
description, opening sentence, and the Core Concepts step bullet).
Audit trail and accountability remain a downstream property, not
the headline framing.

 ### 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

-**`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:

+| `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` |

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

+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
+
+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 against lending policy v3",
+    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,
+            }
+        },
+    },
+]
+
+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.
