+# Research types and custom annotations
+
+Research type describes a claimed characteristic of the work (for example a survey,
+benchmark, empirical study or replication). It is independent of topic, paper length,
+conference track, presentation format and acceptance status. No type is inferred from
+those fields. Multiple source-specific or human classifications may coexist; no
+cross-platform vocabulary mapping or automatic classifier is provided.
+
+`annotation_events` stores both kinds with an explicit `kind` discriminator:
+`research_type` and `tag` are separate domains, even when namespace/value strings
+happen to coincide. Existing platform labels remain in `tags` / `paper_tags`.
+Each assertion carries namespace, value, actor, reason, evidence key, optional source
+record and evidence URL, and the time it was recorded. This is observation time, not
+paper publication time or a conference decision date.
+
+Values are not forced into a global taxonomy: `custom:method=empirical` and
+`platform:declared_type=empirical` retain separate provenance. An explicit platform
+assertion API requires a source record belonging to that paper and matching the
+namespace prefix. The manual CLI only accepts `custom:*`, and cannot retract platform
+assertions. No source type has been automatically assigned to existing papers.
+
+## Initialize explicitly
+
+On the published PostgreSQL dataset, using its protected service file:
+
+```sh
+PGSERVICEFILE=/etc/paper-atlas/pg_service.conf paper-atlas annotate init \
+  --pg-service foundry-research --pg-schema research
+```
+
+This creates one optional table, its indexes, and an upgrade marker in one transaction,
+using the existing dataset writer lock. It does not copy data, change existing papers
+or decisions, or create a PostgreSQL instance. Repeating it is safe; an unexplained
+pre-existing table/marker mismatch fails closed. Readers and ordinary imports do not
+install the extension. Legacy datasets remain readable. A SQLite **sample** uses
+`--db sample.sqlite`; the cutover SQLite backup remains protected against writes.
+
+## Add and retract evidence
+
+Use the canonical paper ID returned by `query`. For a reviewed classification:
+
+```sh
+paper-atlas annotate assert --pg-service foundry-research --pg-schema research \
+  --paper "$PAPER_ID" --kind research_type --namespace custom:method \
+  --value empirical --evidence-key manual:abstract-review \
+  --actor reviewer --reason 'Classified from the explicitly described study design' \
+  --request-id "$REQUEST_ID"
+```
+
+`$REQUEST_ID` must be a new, stable identifier for this action (for example a UUID).
+Retry with the same request ID and identical content after an interrupted response;
+it returns the original event ID. Reusing that ID with changed content is rejected.
+A topic annotation uses `--kind tag --namespace custom:topic --value robotics` instead.
+Optional `--source-record` and `--evidence-url` attach additional evidence; the source
+record must belong to this paper. URLs are retained as evidence and are not fetched.
+
+To withdraw one particular assertion, use its returned event ID:
+
+```sh
+paper-atlas annotate retract --pg-service foundry-research --pg-schema research \
+  --event "$EVENT_ID" --actor reviewer --reason 'Classification corrected after review' \
+  --request-id "$RETRACTION_REQUEST_ID"
+```
+
+Retraction adds an event referencing that assertion, preserving its original content.
+It does not remove another contributor's assertion of the same label, platform tags,
+source metadata or submission/decision history. A retracted assertion can be asserted
+again with a new request ID and evidence; it is a new observation. The API does not
+update or delete past annotation events. Database administrators still control direct
+SQL access. Work reviewed as the same paper may subsequently be merged by the existing
+identity workflow: annotation IDs, original paper IDs, evidence and retraction links
+are retained while the canonical paper reference follows the surviving entity.
+
+## Query and analyze
+
+```sh
+paper-atlas query --pg-service foundry-research --pg-schema research \
+  --research-type custom:method=empirical
+paper-atlas query --pg-service foundry-research --pg-schema research \
+  --tag custom:topic=robotics
+paper-atlas query --pg-service foundry-research --pg-schema research \
+  --paper "$PAPER_ID" --annotation-history
+paper-atlas annotate list --pg-service foundry-research --pg-schema research \
+  --paper "$PAPER_ID" --history
+```
+
+`--tag` includes original platform labels and active annotation tags. It never matches
+research types. `--research-type` matches active type assertions only. Paper details
+return separate `tags` (existing provenance), `annotation_tags`, and `research_types`;
+`--annotation-history` additionally includes retractions. A missing extension yields
+empty annotation results rather than changing the database.
+
+For direct SQL analysis, active research-type evidence is:
+
+```sql
+SELECT a.* FROM research.annotation_events a
+WHERE a.kind = 'research_type' AND a.retracts_id IS NULL
+  AND NOT EXISTS (SELECT 1 FROM research.annotation_events r WHERE r.retracts_id = a.id);
+```
+
+Several independent assertions can support one label; count distinct papers/labels
+when appropriate rather than counting evidence rows as papers. Namespaces stay
+separate. Standard paper queries decode the PostgreSQL text codec; direct SQL consumers
+must honor the dataset's documented codec, including NUL/SOH values. SQLite-to-PostgreSQL
+migration recognizes an installed annotation extension and verifies its full row hashes,
+constraints and identity sequence along with the original business tables. An old
+21-table snapshot stays a 21-table migration; no synthetic annotations are generated.
