🟠 Major · Update the canonical identity algorithm in Section 4. · SIGMA-FLOW.md:120-128
docs/SIGMA-FLOW.md:120-128
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winUpdate the canonical identity algorithm in Section 4.
Section 4 omits the new semantic options from
content_keyand sorts canonical input IDs. The implementation includes these options and preserves input order. The extension section states the intended behavior but does not explicitly supersede the conflicting Section 4 algorithm. Independent implementations can therefore derive different flow identities. Update Section 4 to include all semantic options and ordered inputs.🤖 Prompt for AI Agents

llm and decision nodes include policy_fingerprint computed from node.policy
using the existing term normalization and fingerprint helpers, while preserving
the current node, kind, skipped, and fallback fields for all entries.

Preserve policy attribution in typed traces.
An option-bearing llm node and every decision node use the typed branch. That branch calls opts.run_node but records no policy_fingerprint. The legacy llm branch records it, and the flow contract requires it for each node.
Add policy_fingerprint for llm and decision trace entries.
Proposed fix
- trace[`#trace`+1]={node=id,kind=node.kind,skipped=skipped or false,fallback=fallback}
+ local entry = {
+ node=id,
+ kind=node.kind,
+ skipped=skipped or false,
+ fallback=fallback,
+ }
+ if node.kind == "llm" or node.kind == "decision" then
+ entry.policy_fingerprint = term.fingerprint(term.normalize(node.policy))
+ end
+ trace[`#trace`+1] = entry📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Sigma flows currently express generation nodes but cannot classify structured data and conditionally generate only selected records. Add generic
decisionand puredatanodes (project,select,overlay,union), plus typed JSON output, empty-input skipping, explicit input fallback and bounded model options. No node contains agent, compaction or vendor-specific behavior.Every new semantic field participates in canonical identity; flows without new options retain their existing encoding. Admission checks node options, question schemas, references and policies before effects. The reference driver supports typed values and bounded record operations; the host owns lossless JSON, provider validation, cancellation and accounting.
Validation: 724 Lua assertions pass, including malformed admission, canonical identity, legacy encoding golden, zero-generation empty selection, replacement bounds, fallback and typed scalar assembly. The Python host implementation and operation-conformance tests are in genlayerlabs/unhardcoded#116. That PR makes conversation compaction a JSON preset over these same generic capabilities and adds an unrelated ticket-triage example.
Merge this core change before updating/merging router #116. No deployment is part of these PRs.
