 ## Adapter
 
 - Module key: `seriatim`
-- Document kind: `transcript`
-- Unit kind: `transcript_segment`
 - Source format: `application/vnd.seriatim+json`
 
-The adapter parses raw Seriatim JSON into a generic source document. It owns
-transcript-specific JSON parsing and metadata mapping; core source and pipeline
-code stay source-format agnostic.
-
 ## Accepted Shape
 
 The input must be one JSON object with top-level `metadata` and `segments`
 fields. This covers the maintained minimal fixture and Seriatim intermediate
 output that provides the same required segment fields.
 
-```json
-{
-  "metadata": {
-    "id": "session-alpha",
-    "title": "Synthetic D&D spell session"
-  },
-  "segments": [
-    {
-      "id": 1,
-      "start": 0,
-      "end": 4,
-      "speaker": "Aria",
-      "text": "Aria raises her holy symbol and casts Cure Wounds."
-    }
-  ]
-}
-```
-
 The maintained example is
 [examples/seriatim-minimal-transcript.json](../../examples/seriatim-minimal-transcript.json).
 
-Top-level metadata entries are preserved. Other segment fields, such as
-`categories`, are ignored.
+Required top-level fields:
+
+- `metadata`: an object. Its entries are accepted as source metadata.
+- `segments`: a non-empty array of segment objects.
+
+Required segment fields:
+
+- `id`: a positive integer JSON number or canonical decimal string without
+  leading zeros or surrounding whitespace;
+- `start`: a finite, non-negative JSON number or numeric string;
+- `end`: a finite, non-negative JSON number or numeric string that is not less
+  than `start`;
+- `speaker`: a non-empty string;
+- `text`: a non-empty string.
+
+Other top-level and segment fields, such as `categories`, are ignored.
 
 Multiple top-level JSON values are rejected.
 
 ## Validation
 
-The adapter rejects:
-
-- empty raw input;
-- malformed JSON;
-- top-level JSON that is not an object;
-- missing, null, or non-object `metadata`;
-- missing, null, non-array, or empty `segments`;
-- segment values that are not objects;
-- segment `id` values that are not positive integer JSON numbers or numeric
-  strings;
-- non-string `speaker` or `text`;
-- duplicate segment IDs;
-- missing or empty `speaker`;
-- missing, empty, invalid, non-finite, or negative `start`;
-- missing, empty, invalid, non-finite, or negative `end`;
-- `end` values before `start`;
-- missing or empty `text`.
+The adapter rejects empty input, malformed JSON, multiple top-level JSON values,
+non-object segment values, duplicate segment IDs, and any violation of the
+shape or field constraints above.
 
 Segment text is preserved as provided, but it must not be empty after trimming.
 
-## Source Mapping
+## Derived Identity
 
-The adapter maps input to `SourceDocument`:
+Notarius identifies the parsed source in this order:
 
-- `metadata` becomes `SourceDocument.Metadata`;
-- `SourceDocument.Kind` is `transcript`;
-- `SourceDocument.Format` is `application/vnd.seriatim+json`;
-- `SourceDocument.Digest` is `sha256:<hex>` of the exact raw input bytes.
+1. `metadata.id`, when it is a non-empty string after trimming;
+2. `metadata.source_id`, when it is a non-empty string after trimming;
+3. `seriatim:<first-16-hex-chars-of-raw-sha256>`.
 
-`SourceDocument.ID` is selected in this order:
-
-1. the parse request source ID, after trimming;
-2. `metadata.id`, when it is a non-empty string after trimming;
-3. `metadata.source_id`, when it is a non-empty string after trimming;
-4. `seriatim:<first-16-hex-chars-of-raw-sha256>`.
-
-Each segment becomes one `SourceUnit`:
-
-- `segment.id` becomes integer `SourceUnit.ID`;
-- `segment.text` becomes `SourceUnit.Text`;
-- `SourceUnit.Kind` is `transcript_segment`;
-- `speaker`, `start`, and `end` are stored in source-unit metadata.
-
-## Metadata Keys
-
-Seriatim unit metadata uses these keys:
-
-- `speaker`: string speaker label;
-- `start`: `json.Number` start value;
-- `end`: `json.Number` end value.
-
-The `internal/modules/input/seriatim` package exposes typed accessors for these
-values.
-
-## Capabilities
-
-The module declares these provided capabilities:
-
-- `source.transcript`
-- `transcript.speaker`
-- `transcript.timestamps`
+The source digest recorded in output provenance is `sha256:<hex>` of the exact
+raw input bytes. Segment IDs become the unit IDs used by artifact source
+references.
