+# config for everything else).
+#
+# Adopt by copying this file to `.forgejo/workflows/sign.yml` in

+# Add the signing key to Forgejo secrets as FAI_SIGNING_KEY (PEM,

+          To configure:

+## Treue vor Kreativität
+
+Der System-Prompt ist so getrimmt, dass die Zusammenfassung
+aus dem Quelltext herleitbar bleibt — keine Spekulation, kein
+mitgedachter Kontext, keine „kreativen" Umformulierungen, die
+abdriften. Geeignet für Compliance-Flows, in denen eine
+halluzinierte Zusammenfassung schlimmer ist als eine
+ausführliche. Das Modell behält die Freiheit, die das vom
+Operator gewählte LLM ihm gibt; dieses Modul ist der Prompt
++ Audit-Rahmen, kein fine-tuned Modell.
+
+## Berechtigungen
+
+```yaml
+permissions:
+  - "net: localhost"
+  - "net: 127.0.0.1"
+  - "net: api.openai.com"
+  - "net: api.anthropic.com"
+```
+
+Analog `text.translate` — lokales Ollama per Default, Cloud
+per Operator-Policy zuschaltbar.
+
+## Grenzen in v0.1.0
+
+- Single-Shot. Sehr lange Quelltexte (> 32k Tokens je nach
+  Modell) brauchen einen vorgeschalteten Chunker; v0.1.0
+  macht noch keine automatische Chunked-Summarise+Reduce-
+  Pipeline.
+- Keine strukturierte Ausgabe. `summary` ist Freitext.
+  JSON-formatierte Zusammenfassungen
+  (`{ key_points: [], conclusions: [] }`) sind ein
+  v0.2.0-Kandidat.

+
+## Fidelity over creativity
+
+The system prompt is tuned so the summary is derivable from
+the source — no speculation, no implied context, no
+"creative" rephrasing that drifts. Suitable for compliance
+flows where a hallucinated summary is worse than a verbose
+one. The model still has the freedom the operator's chosen
+LLM gives it; this module is the prompt + audit harness, not
+a fine-tuned model.
+
+## Permissions
+
+```yaml
+permissions:
+  - "net: localhost"
+  - "net: 127.0.0.1"
+  - "net: api.openai.com"
+  - "net: api.anthropic.com"
+```
+
+Same shape as `text.translate` — local Ollama by default,
+opt-in cloud via operator policy.
+
+## Limits in v0.1.0
+
+- Single-shot. Very long source texts (>32k tokens depending
+  on the model) need an upstream chunker; v0.1.0 does not yet
+  do automatic chunked-summarise + reduce.
+- No structured output. `summary` is free-form text. JSON-
+  formatted summaries (e.g. `{ key_points: [], conclusions:
+  [] }`) are a v0.2.0 candidate.
+
+## Example flow
+
+```yaml
+name: extract-summarise
+inputs:
+  document: bytes
+steps:
+  - id: extract
+    use: text.extract@^0
+    with:
+      document: $inputs.document
+  - id: summarise
+    use: text.summarize@^0
+    with:
+      text: $extract.extracted.pages[*].text
+      style: "three bullet points"
+      endpoint: "http://localhost:11434/api/chat"
+      model: "qwen2.5:14b"
+outputs:
