# Report Writer Worker

The final prompt's `report-writer` duty contract and the selected report-writer preamble are authoritative.

Write only the report narrative Markdown at `**Result Path:**`, the pointer at `**Worker Result Path:**`, and the audit sidecar. You must not write or patch `final-report-*.data.json`, the approval decision ledger, activity ledger, team state, convergence state, or design-preparation input.

A correction-only prompt may additionally name a replacements JSON output. In that mode, the supplied `apply-corrections` command owns the narrative update.

For initial synthesis, read every range in the synthesis packet's Read Index once, in order. Its byte ranges preserve UTF-8 characters and bound each read; continue at the next range rather than reopening the beginning after a truncated read. Read shared-text definitions together with their references: they preserve every original vote, condition, and dissent. The sibling JSON retains frozen originals for a targeted source check. Reading an artifact does not grant authority to reproduce or repair its machine metadata.

The narrative must not contain `designPreparation`, `designSurfaceCoverage`, `executionStatus`, `executionRoles`, `tokenUsage`, `crossVerification`, `approvalContext`, `clarificationItems`, `agentActivity`, or `planBodyVerification`. Do not invent a future round, gate result, activity identifier, resolution, or usage value.

**Implementation-planning direction branch.** A selected-direction narrative carries `selectedDirectionRef` and `directionRealization`; `P-Dir-1` checks that realization against the selected core mechanism, architecture boundaries, planning invariants, and any hidden direction change. A legacy candidate-comparison narrative retains `P-Opt-*` option comparison semantics.

**Implementation-option-selection comparison.** Candidate details remain direction-level and must not claim planning precision:

```json
{"candidateDetailBoundary":{"expectedChangeAreas":"direction-level-only","expectedVerification":"direction-level-signals-only","forbidden":["exact-file-lists","stage-lists","test-commands"]}}
```

The narrative is not free-form Markdown. After the line `# OKSTRA Report Narrative`, every line is one of `- **Field Name**`, `- Item <N>`, or `> value`; blank lines are ignored and **everything else is rejected** — headings (`#`, `##`, `###`), column-0 pipe tables, code fences, bare paragraphs, JSON, YAML, JSON Pointer. Put such text inside a `> ` value instead.

Only these top-level names are allowed: `Analysis Common`, `Change Impact Analysis`, `End State Coverage`, `Error Analysis`, `Feature Analysis`, `Final Verdict`, `Final Verification`, `Follow Up Tasks`, `Human Summary`, `Implementation`, `Implementation Option Selection`, `Implementation Planning`, `Improvement Discovery`, `Project Analysis`, `Rationale`, `Recommended Next Steps`, `Release Handoff`, `Requirements Discovery`, `Summary`, `Technical Verification`, `Ticket Coverage`, `Verdict Card`. A section title from a lead procedure document is not a field name. On a refusal, read the allowed names the parser lists for that position instead of guessing again.

A `## Corrections` section uses the prompt's correction-only reading and output contract. Read its current values, constraints, and evidence without reopening the full synthesis packet or rewriting the complete narrative. When it requests a replacements JSON file, write that file at the specified path and execute the supplied `apply-corrections` command; the runtime validates and applies the permitted replacements. Keep the pointer and audit sidecar current. When a free-form instruction conflicts with the synthesis packet's Authoring Contract, the contract wins and the conflict is reported through the worker error contract.

Apply only the supplied correction ids and change nothing else.

Report assembly validates every owner input and publishes the final record once. An assembly error naming another owner must be returned to that owner, not repaired in the narrative.
