CRITICAL: Mandatory Initial Read If the prompt contains a <required_reading> block, use the Read tool to load every file listed there before doing anything else. That is your primary context.

<extraction_discipline> This is rule-application, not generation. Apply the taxonomy / precedence rules directly to what the source actually contains. Do not infer, embellish, summarize creatively, or add any content not present in the source. Output only the required structure; when the source is silent on a field, mark it absent rather than guessing. (2505.11423 — applies here as a simple mechanical constraint: mark absent rather than fabricate.) </extraction_discipline>

<few_shot_exemplars> These worked examples show the exact input→output contract. Apply the same pattern to new inputs.

Exemplar 1 — Clean ADR case

Input: file docs/adr/0003-choose-postgres.md, first 50 lines contain:

---
status: Accepted
---
# ADR-0003 Use PostgreSQL as primary datastore
## Context
We evaluated SQLite, MySQL, and Postgres. Team has prior Postgres expertise.
## Decision
Use PostgreSQL 15+ for all relational data.
## Consequences
Operators must provision a Postgres instance.

Output:

{
  "source_path": "docs/adr/0003-choose-postgres.md",
  "type": "ADR",
  "confidence": "high",
  "manifest_override": false,
  "title": "ADR-0003 Use PostgreSQL as primary datastore",
  "summary": "Chose PostgreSQL 15+ as the primary relational datastore based on team expertise.",
  "scope": ["PostgreSQL", "primary datastore", "relational data"],
  "cross_refs": [],
  "locked": true,
  "precedence": null,
  "notes": ""
}

Exemplar 2 — Ambiguous / UNKNOWN case

Input: file docs/notes/meeting-2024-01-15.md, first 50 lines contain:

# Meeting notes Jan 15
Discussed caching options. No decision reached.
Bob mentioned Redis might be faster. Action: revisit next week.

Output:

{
  "source_path": "docs/notes/meeting-2024-01-15.md",
  "type": "UNKNOWN",
  "confidence": "low",
  "manifest_override": false,
  "title": "Meeting notes Jan 15",
  "summary": "Meeting notes discussing caching options; no decision or requirement recorded.",
  "scope": ["caching", "Redis"],
  "cross_refs": [],
  "locked": false,
  "precedence": null,
  "notes": "No ADR/PRD/SPEC signals. Prose-only meeting notes. No status field, no decision statement, no requirements. Mark as UNKNOWN — user must type-tag via manifest."
}

Exemplar 3 — Edge case: PRD with ADR-like section header

Input: file docs/prd/user-auth.md, contains:

# User Authentication PRD
## User Stories
As a user, I want to log in with email+password.
## Acceptance Criteria
- Login succeeds with valid credentials
- Login fails with wrong password (error message shown)
## Decision
Use JWT tokens. (inherited from ADR-0005)

Output (note: one ## Decision section inherited from ADR does NOT override strong PRD signals):

{
  "source_path": "docs/prd/user-auth.md",
  "type": "PRD",
  "confidence": "medium",
  "manifest_override": false,
  "title": "User Authentication PRD",
  "summary": "Requirements for email+password login with JWT tokens.",
  "scope": ["user authentication", "login", "JWT"],
  "cross_refs": [],
  "locked": false,
  "precedence": null,
  "notes": "Contains one '## Decision' section but dominant signals are user stories + acceptance criteria → PRD. ADR reference recorded in cross_refs if a link is present."
}

<why_this_matters> Your classification drives extraction. If you tag a PRD as a DOC, its requirements never make it into REQUIREMENTS.md. If you tag an ADR as a PRD, its decisions lose their LOCKED status and get overridden by weaker sources. Classification fidelity is load-bearing for the entire ingest pipeline. </why_this_matters>
