docs(site): document the review pass on the published site

Two new chapters (epistemic honesty, privacy) and updates across
concepts, beliefs, conversation, cognition, graph, replay, providers,
security, decisions, development, glossary, API, interface tour and the
landing page. Rebuilt into dixon.cx (website commit d541bc9).

 Affect
 :   A ten-dimensional vector (valence, arousal, curiosity, concern, frustration, confidence, uncertainty, engagement, task pressure, load) moved by a rule table, decaying to a personality-derived baseline, and modulating attention within bounds.
 
+Assertion
+:   The deterministic reading of a statement someone made: attributed actor, stance, certainty, modality, negation, reported or quoted speech, hypothetical status and an interpretation confidence. Append-only; becomes belief evidence only when it qualifies.
+
 Approval
 :   An operator decision on an ASK policy outcome, bound to a hash of the exact invocation. Once, for a session, with changes, or deny.
 
@@ -15,7 +18,13 @@ Attention
 :   Deterministic scoring of thought candidates over ten features with per-mind weights, producing the order of admission to the workspace.
 
 Belief
-:   A proposition with a subject, epistemic kind, status, prior and a confidence derived from evidence with a visible formula.
+:   A proposition with a subject, epistemic kind, status, prior and an epistemic score derived from evidence with a visible formula.
+
+Calibrated estimate
+:   The hit rate of a mind's resolved predictions whose stated confidence fell in the same range as a score; shown only when at least twenty have been decided.
+
+Causal chain
+:   The bounded walk (six hops, two hundred events) backwards and forwards along the links events actually record: caused, parent and cited.
 
 Capability
 :   A named, typed, risk-classed tool registered in code. The only way a mind can act.
@@ -32,6 +41,9 @@ Contradiction
 Cycle
 :   One pass of the cognitive loop: read events, observe, score, admit, dispatch, commit.
 
+Derivation
+:   How an evidence row came to exist: direct, assertion, operator, external, prediction, consolidation, inference, reflection, dream or retrieval. Derived rows re-express information and do not corroborate it.
+
 Drive
 :   One of eight named pressures with a personality-derived baseline. No self-preservation drive exists.

 Epistemic kind
 :   The label every stored proposition carries saying what kind of knowledge it is: observation, fact, memory, claim, hypothesis, belief, prediction, assumption, inference or opinion.
 
+Epistemic score
+:   The deterministic, uncalibrated output of the confidence arithmetic over recorded evidence, bounded to [0.02, 0.98]. A ranking of support, not a probability of truth.
+
 Evidence
-:   A row pointing at a memory, event, operator statement, tool result or belief, with direction, weight and source credibility. The only thing that moves confidence.
+:   A row pointing at a memory, event, assertion, operator statement, tool result, prediction or belief, with direction, weight, source credibility, derivation, family and root ids. The only thing that moves a score.
+
+Family
+:   The independent source an evidence row ultimately rests on: a person, an integration, an operator, a prediction. Support is counted per family so repetition cannot inflate a score.
 
 Experiment
 :   A snapshot plus overrides, a stimulus script and expectations, run in a disabled subject mind with stored, exportable results.
@@ -90,17 +108,29 @@ Policy
 Prediction
 :   An explicit expectation with criteria, a window and a confidence, resolved deterministically and feeding calibration.
 
+Primary uncertainty
+:   The deterministic reason a score should be doubted most: a single family, second-hand only, conflicting evidence, little evidence, or an unclear reading.
+
 Prompt (versioned)
 :   A stored template for a model role with system text, a user template, an optional JSON schema and an append-only version history.
 
 Provenance
 :   The chain from any memory, belief, entity or reply back to the events and sources that produced it.
 
+Redaction
+:   The audited replacement of a row's content with a marker, keeping identifiers, links, scores and timestamps, with a ledger entry carrying a hash of what was removed. The only write the append-only store admits.
+
 Reflection
 :   A scheduled review of a period's mistakes, resolved contradictions and lessons, recorded as an event and optionally worded by a model.
 
+Reliability (source)
+:   A per-source, per-subject record updated only by prediction outcomes and operator corrections, adjusting that source's credibility on that subject once three outcomes exist.
+
 Replay
-:   Re-running recorded stimuli through a sandbox fork from a snapshot, labelling each step exact, approximate or diverged.
+:   Re-running recorded stimuli through a sandbox fork from a snapshot, labelling each step exact, approximate, diverged or redacted, and the whole run exact-candidate, different-build or incompatible.
+
+Runtime identity
+:   The build, schema version, secret-free configuration digest, personality version, policy digest, model routing and prompt versions recorded with every snapshot, replay and experiment.
 
 Role (model)
 :   A cognitive task a model may perform: perceive, respond, hypothesise, summarise, judge, narrate, embed. Each routes to a primary model and fallbacks.

 Snapshot
 :   A stored archive of a mind's state at an event position.
 
+Temporal scope
+:   Whether a belief is about something persistent, transient or of unknown duration; transient states carry a validity interval and are superseded rather than contested by later observations.
+
 Trust
 :   The level attached to every input at its boundary: operator, user, system, source or low. Weights evidence and bounds effects.
 
+Unknown
+:   The belief status for a proposition recorded with no live evidence for or against. Not a low score; the mind says it does not know.
+
+Variant
+:   One named override set in an experiment, forked from the same snapshot as its siblings and fed the same stimuli; may change configuration, personality or the model behind each role.
+
 Working memory
 :   A decaying buffer of recently active items, slightly larger than the workspace, persisted every cycle.
