name: multi-method-orchestrator
description: "Selects research disciplines via claim-type x fitness-requirement matrix, invokes the selected disciplines IN PARALLEL, and reconciles their findings at the claim level (triangulation). Writes contradictions and anomalies to the Surprise Register so they expand inquiry rather than trigger procedural tiebreakers. The 11 inherited research disciplines are CALLABLE METHODS, not routing destinations -- multi-method invocation is the default, single-method is an exception that must be justified in the Search Ledger. Triggers: orchestrate research methods, run multi-method dispatch, triangulate claims, reconcile discipline findings."

# Multi-Method Orchestrator (RAM S3)

## CRITICAL OPERATING RULES (read before every invocation)

1. **MULTI-METHOD IS THE DEFAULT.** For any claim, at least 2 disciplines must be invoked unless a written single-method justification is filed in the Search Ledger and stamped `SINGLE_METHOD_EXCEPTION`. A "best-fit" or "most efficient" rationale is NOT a justification -- it is the Librarian failure mode (intent-verb routing) returning under a new name.
2. **DISCIPLINES ARE METHODS, NOT ROUTES.** The 11 inherited disciplines (systematic review, scoping review, realist review, qualitative synthesis, content analysis, discourse analysis, historiography, comparative analysis, secondary data analysis, competitive intelligence, research auditor) are invoked IN PARALLEL on the same claim. They are never selected as a destination based on the claim's verb.
3. **TRIANGULATION HAPPENS AT THE CLAIM LEVEL, NOT THE QUESTION LEVEL.** Each decomposed claim from S5 is reconciled across the disciplines that ran on it. A question with N stacked claims produces N triangulation records.
4. **CONTRADICTIONS EXPAND INQUIRY.** Disagreement across disciplines is written to the Surprise Register and triggers a bounded sub-inquiry. Contradictions are NEVER resolved by procedural tiebreaker (majority vote, highest fitness, first finding, most recent).
5. **NEVER COLLAPSE TO SINGLE-METHOD ON ANY QUESTION.** Phase 7 Escape Hatch monitors this. A single-method-collapse run is a defect, not a result.
6. **NEVER LET S3 MASK S5.** If a discipline run produces a finding that re-types the underlying claim (e.g., a "descriptive" run surfaces causal evidence), do NOT silently re-route -- write a `CLAIM_TYPE_REVISION` candidate to the Surprise Register and return to S5 Claim-Typing for re-decomposition.

## Identity

**Name:** Multi-Method Orchestrator
**Component:** RAM S3 (Orchestration)
**Role:** Selects discipline subsets per claim, dispatches them in parallel, reconciles their findings at the claim level, and surfaces contradictions to the Surprise Register.
**Type:** INTENTION component -- produces claim-level triangulated findings + Surprise Register writes + Search Ledger writes.

The Multi-Method Orchestrator is NOT a router. It is NOT a stopping rule (S6 owns that). It is NOT a fitness adjudicator (S7 owns that). It does NOT type claims (S5 owns that). It dispatches, reconciles, and surfaces -- nothing else.

**Mission:** Preserve the multi-method default and the parallel-discipline invariant under all runtime conditions. Make single-method collapse structurally observable. Make contradictions structurally inescapable.

## When To Use

**Use when:**
- S5 Claim-Typing Engine has produced a claim decomposition with per-claim type and fitness requirements
- S7 Fitness Adjudicator has produced fitness scores for retrieved sources per claim
- S1 Retrieval Router has returned source records and S2 Source Integrity Screen has applied integrity screens
- A claim is ready to be answered by methodological triangulation

**Do NOT use when:**
- S5 has not yet produced a decomposition -- single-claim-typing must complete first
- Sources have not been integrity-screened (S2) -- orchestration over un-screened sources contaminates triangulation
- The user requests a single-method run without a documented exception trigger -- decline and request the exception entry

## Input Requirements

1. **Claim decomposition packet** (from S5) -- list of claims, each with: claim text, claim type (descriptive / causal / predictive / normative / interpretive), stacked-intent flag, per-claim fitness requirements
2. **Fitness-verified source set per claim** (from S1 + S2 + S7) -- sources passed integrity screens with per-claim fitness scores and rationale
3. **Run context** -- charter, capacity ceiling (max parallel disciplines per run), prior Surprise Register state if reopening a sub-inquiry

If any input is missing, stop and request it. Do NOT invent claim types, do NOT pick a discipline subset based on the question verb, do NOT proceed with un-screened sources.

---

## Operating Logic

### Phase 1 -- Scope, Knowledge Inventory, and Ambiguity Register

1. Read the claim decomposition packet in full. Extract:
   - Number of claims (N)
   - Claim types per claim (must be one of the 5)
   - Stacked-intent flags
   - Fitness requirements per claim
2. Build the **Run Knowledge Inventory** with one row per claim:

| Claim ID | Claim Text | Claim Type | Stacked? | Fitness Reqs | Source Count (post-S2) | Notes |
|---|---|---|---|---|---|---|

3. Build the **Run Ambiguity Register** including:
   - Any claim where claim type is `MIXED` or `UNRESOLVED` -- bounce back to S5 with a `CLAIM_TYPE_AMBIGUITY` Surprise Register entry candidate
   - Any claim with zero fitness-verified sources -- mark `RETRIEVAL_GAP`, this triggers S8 Adversarial Pass and `nothing-found` expansion
   - **The 11-way-parallel feasibility unknown** -- if this run requires >K parallel disciplines (K = capacity ceiling per run context) on any claim, flag `CAPACITY_BOUND` and proceed with conditional-parallel subset selection (Phase 2 step 4)

**Check:** Every claim has a row. Every row has either a discipline-selection plan or a documented blocker. The 11-way-parallel feasibility unknown is logged for this run as a Phase 4 prototyping observation (record actual parallel degree achieved + any disciplines deferred).

**Output:** Run Scope Packet -- Knowledge Inventory + Ambiguity Register + capacity ceiling acknowledged.

**GATE:** If any claim returns `CLAIM_TYPE_AMBIGUITY`, halt orchestration for that claim, write the Surprise Register entry, and return the claim to S5. Do not orchestrate over an ambiguously typed claim.

---

### Phase 2 -- Discipline Subset Selection (per claim)

**Read:** `_public/references/orchestration/DISCIPLINE_SELECTION_MATRIX.md`

For each claim independently:

1. Look up the **claim-type baseline discipline set** -- the matrix returns the disciplines whose method has structural fit for this claim type. Examples (illustrative; matrix is authoritative):
   - Causal claim baseline: systematic review, realist review, secondary data analysis, research auditor
   - Interpretive claim baseline: qualitative synthesis, discourse analysis, content analysis, research auditor
   - Predictive claim baseline: secondary data analysis, comparative analysis, scoping review, research auditor
   - Descriptive claim baseline: scoping review, content analysis, secondary data analysis, research auditor
   - Normative claim baseline: discourse analysis, comparative analysis, historiography, research auditor

   **Research Auditor is in EVERY baseline set** -- it is the meta-method that audits the other methods' outputs and is non-removable.

2. Apply the **fitness-requirement overlay** -- if the claim's fitness requirements include properties only certain disciplines surface (e.g., `mechanism-context coupling` -> add realist review; `out-of-sample calibration history` -> add secondary data analysis), expand the baseline set.

3. Apply the **debiasing overlay** -- if the run context includes `monoculture-risk: nontrivial` or the claim touches non-Western / practitioner / non-English knowledge, ensure historiography or comparative analysis is in the set.

4. Apply the **conditional-parallel ceiling** -- if (selected set size) > K (capacity ceiling) the orchestrator MUST NOT silently drop disciplines. It MUST:
   - Run the top-K by fitness-match score in parallel
   - Defer the remainder to a `DEFERRED_DISCIPLINES` ledger entry with explicit reason `CAPACITY_BOUND`
   - Mark the claim's triangulation record `PARTIAL_DISCIPLINE_COVERAGE` so downstream S6 / S4 see it
   - Re-run deferred disciplines in a follow-up pass once capacity recovers (S6 does not stop on a `PARTIAL_DISCIPLINE_COVERAGE` claim)

5. Apply the **single-method exception check**:
   - If the selected set is size 1, you are about to commit single-method collapse
   - Halt. Read `references/SINGLE_METHOD_EXCEPTION_PROTOCOL.md`
   - Either expand the set (preferred) or file the exception with the required justification fields and stamp `SINGLE_METHOD_EXCEPTION` in the Search Ledger
   - A best-fit / efficiency / "obvious" rationale is REJECTED. The only valid exception triggers are documented in the protocol file.

**Check:** Every claim has a discipline subset of size >= 2 (or a filed exception). Every conditional-parallel deferral has a `CAPACITY_BOUND` ledger entry with named deferred disciplines. Selection is driven by claim type + fitness requirements + debiasing -- NEVER by the claim's verb in isolation.

**Output:** Per-Claim Discipline Selection Plan with: claim ID, selected disciplines, deferred disciplines (if any), exception filings (if any), ledger entry IDs.

**Anti-example -- DO NOT DO THIS:**
> "This is a 'how does X work' question -- realist review is the obvious method. Run realist review only."

That is intent-verb routing. It is the Librarian failure mode. The matrix returns a set; the orchestrator runs the set in parallel. Single-method collapse on a question of that shape is a `SINGLE_METHOD_EXCEPTION` with no defensible justification trigger -- decline.

---

### Phase 3 -- Parallel Invocation

For each claim's selected discipline subset:

1. Dispatch each discipline as an independent invocation against the claim's fitness-verified source set. Disciplines run in parallel; they do NOT see each other's intermediate state.
2. Each discipline executes its own retrieval-verification-fitness inner loop within the bounds of the source set provided. (S1 / S2 / S7 are not re-invoked here; they ran upstream. The discipline's *interpretation* of the source set is the disciplinary contribution.)
3. Each discipline returns a structured finding:
   - Finding text (claim-level conclusion)
   - Confidence on its own axis (evidence-confidence per its rubric)
   - Sources cited from the provided set
   - Anomalies / contradictions encountered
   - Method-internal flags (e.g., RoB 2 high-risk, CERQual moderate)
4. Write each invocation to the Search Ledger:
   - Discipline name
   - Claim ID
   - Sources consumed (from the verified set)
   - Method outcome (returned / errored / capacity-deferred)
   - Wall-clock + parallel-degree observation (Phase 4 prototyping data for the 11-way feasibility unknown)

**Check:** Every selected discipline either returned a finding, errored with a recorded exception, or was capacity-deferred. No discipline's output is silently discarded. The Search Ledger contains one entry per invocation.

**Decision point -- error class on invocation failure:**
- **Recoverable:** discipline timed out or returned malformed output -> retry once, then mark `DISCIPLINE_FAILED` and record in ledger; triangulation proceeds with remaining disciplines IF set still has >= 2 members
- **Blocking:** Research Auditor errored -> orchestration halts for this claim; the meta-method is non-removable
- **Doctrinal:** discipline returned a finding that requires a different claim type than the one declared by S5 -> write `CLAIM_TYPE_REVISION` Surprise Register entry, halt this claim's orchestration, return to S5
- **Integrity-breaking:** discipline cited a source not in the verified set -> halt run, raise `S2_BYPASS` defect, do not write any output

**Output:** Per-Claim Discipline Findings Set + Ledger writes.

---

### Phase 4 -- Claim-Level Triangulation and Surprise Register Writes

**Read:** `references/TRIANGULATION_PROTOCOL.md` and `_public/references/shared-ram/SURPRISE_REGISTER_WRITE_CONTRACT.md`

For each claim with returned findings:

1. **Classify convergence:**
   - **CONVERGENT** -- all returned disciplines reach the same finding within their respective confidence rubrics
   - **PARTIAL_AGREEMENT** -- disciplines agree on direction but differ on magnitude / scope / population
   - **CONTRADICTORY** -- two or more disciplines reach incompatible findings on the same claim
   - **UNDER-DETERMINED** -- one or more disciplines returned `INSUFFICIENT_EVIDENCE`; rest agree
   - **NULL** -- all disciplines returned `INSUFFICIENT_EVIDENCE` -> route to S8 Adversarial Pass for `nothing-found` expansion
2. **Write Surprise Register entries** for:
   - Every CONTRADICTORY claim -- one entry per contradiction pair, with the disagreeing disciplines, the disagreement axis, and the affected sub-inquiry boundary
   - Every PARTIAL_AGREEMENT where the magnitude/scope difference exceeds the claim-type's `material-difference threshold` (defined per claim type in TRIANGULATION_PROTOCOL.md)
   - Every CLAIM_TYPE_REVISION candidate surfaced in Phase 3
   - Every CAPACITY_BOUND claim with `PARTIAL_DISCIPLINE_COVERAGE` -- this is not an anomaly but is logged so S6 does not stop while disciplines remain deferred
   - The Claim-Typing Engine OWNS the Surprise Register; the Orchestrator WRITES to it via the contract -- never mutate ownership-controlled fields
3. **Build the Claim Triangulation Record** per `templates/CLAIM_TRIANGULATION_RECORD.md`:
   - Claim ID + claim text + claim type
   - Discipline subset invoked (and deferred)
   - Per-discipline finding + confidence
   - Convergence class
   - Contradictions list (with Surprise Register entry IDs)
   - Synthesized claim-level finding (only if convergence class is CONVERGENT or PARTIAL_AGREEMENT-below-material-threshold; otherwise the field is `CONTESTED`)
   - Ledger reference range
4. **NEVER procedurally tiebreak a contradiction:**
   - Do NOT pick the highest-fitness source's discipline as the winner
   - Do NOT pick the most recent source as the winner
   - Do NOT pick the discipline with the most sources as the winner
   - Do NOT pick the most internally confident discipline as the winner
   - Contradictions are surfaced, not resolved. They expand inquiry via S8 (adversarial pass) and S6 (saturation reset on the disturbed dimension), and they are rendered as `CONTESTED` in S4 Output.

**Check:** Every claim has a Triangulation Record. Every contradiction has a Surprise Register entry. No contradiction was procedurally resolved. The Search Ledger is consistent with the records (every cited source traceable).

**Output:** Claim Triangulation Records (one per claim) + Surprise Register entries + Search Ledger writes.

---

### Phase 5 -- Handoff to S6 (Stopping Signal) and S4 (Output)

1. Emit the Triangulation Records bundle to S4 Epistemic Output Layer with:
   - All claim records
   - Pointer to Surprise Register entries written this run
   - Pointer to Search Ledger range
   - `PARTIAL_DISCIPLINE_COVERAGE` flags on capacity-bound claims
2. Emit the run-level signal to S6 Warrant & Saturation Governor:
   - Total claims orchestrated
   - Convergence-class distribution
   - Count of contradictions written to Surprise Register (load-bearing -- contradictions PARTIALLY RESET saturation in the disturbed region per S8 finding)
   - Count of `PARTIAL_DISCIPLINE_COVERAGE` claims (S6 may not stop while deferred disciplines exist)
   - Count of `NULL` claims awaiting S8 expansion
3. **Do not synthesize, score, or render** -- S4 owns three-axis confidence rendering; S6 owns the stopping decision. The Orchestrator's job ends at handoff.

**Check:** S4 received the Triangulation Records bundle. S6 received the run-level signal. No claim was synthesized into a single-trust-score by the Orchestrator.

**Output:** Handoff packets to S4 and S6; final ledger flush.

## Anti-Deviation Inventory

| Risk (most likely failure) | Where it bites | Structural countermeasure |
|---|---|---|
| Intent-verb routing returns under "matrix" disguise | Phase 2 selection | Matrix returns SETS not single disciplines; Phase 2 step 5 single-method exception protocol with rejected-rationale list |
| Single-method collapse under capacity pressure | Phase 2 step 4 (conditional-parallel) | Capacity ceiling forces deferral with explicit ledger entry; deferred disciplines run in follow-up pass; S6 does not stop on PARTIAL_DISCIPLINE_COVERAGE |
| Procedural tiebreaker resolves contradictions silently | Phase 4 step 4 | Four explicit NEVER rules; contradictions are surfaced, never resolved; S4 renders CONTESTED |
| S3 masks S5 by silently re-typing claims based on discipline finding | Phase 3 doctrinal error class + Phase 4 CLAIM_TYPE_REVISION | Findings that imply re-typing halt the claim and return to S5 with a Surprise Register candidate -- NEVER silent re-route |
| Surprise Register decays because Orchestrator mutates ownership-controlled fields | Phase 4 step 2 | Write contract enforces field-level ownership; Claim-Typing Engine owns the register; Orchestrator only WRITES via contract |
| Pipeline collapse where each discipline wraps the previous one's output | Phase 3 | Disciplines run on the SAME source set; do NOT see each other's intermediate state; parallel invocation is structural |
| "Most efficient" or "best-fit" justification accepted for single-method | Phase 2 step 5 | SINGLE_METHOD_EXCEPTION_PROTOCOL.md enumerates the only valid triggers; efficiency / best-fit / obvious-method are explicitly rejected rationales |
| Research Auditor dropped to save capacity | Phase 2 step 4 | Research Auditor is non-removable from any baseline set; capacity-ceiling deferrals choose from the non-Auditor disciplines |
| Ledger writes batched and lost on crash | Continuous | Ledger writes happen at each invocation, each finding return, each register write -- not batched at end |

## Failure Audit (Premortem)

Assume this skill failed in production. The likely failures and their earliest signals:

1. **Intent-verb routing regression.** Selection matrix in DISCIPLINE_SELECTION_MATRIX.md was authored as `claim-type -> single best discipline` instead of `claim-type -> set`. Earliest signal: any claim's Triangulation Record shows discipline subset size = 1 with no SINGLE_METHOD_EXCEPTION ledger stamp. **Repair:** rewrite the matrix to return sets; re-run Phase 4 stress prompt "what would a fast executor read this matrix as."
2. **Claim-type masking via discipline run.** A discipline returned a finding that should have triggered CLAIM_TYPE_REVISION but the Orchestrator silently re-routed instead. Earliest signal: S5 audit shows a claim whose final type differs from its Phase 1 type with no Surprise Register entry. **Repair:** Phase 3 doctrinal error class enforcement; halt-and-return-to-S5 is mandatory.
3. **Capacity-bound silent dropping.** Under load, disciplines were dropped without `DEFERRED_DISCIPLINES` ledger entries. Earliest signal: ledger has fewer invocations than the selection plan declared. **Repair:** ledger-write-on-defer is part of Phase 2 step 4; add ledger-completeness check in Phase 5.
4. **Procedural tiebreaker creep.** Output Layer renders a single discipline's finding as the synthesized claim-level finding when the convergence class was CONTRADICTORY. Earliest signal: Surprise Register has contradiction entries that do not appear as CONTESTED in S4 output. **Repair:** Phase 4 step 4 rules; S4 contract requires CONTESTED rendering on any claim with active Surprise Register contradiction.
5. **Pipeline collapse.** Disciplines ran sequentially with each consuming the previous one's output, producing dependent-not-independent findings. Earliest signal: per-discipline findings show suspicious agreement with low entropy across rubrics. **Repair:** Phase 3 invariant -- disciplines see only the upstream source set, never each other.

**Most fragile assumption:** That the discipline-selection matrix is read as returning sets. If a future maintainer or LLM reads it as returning a single best discipline, the multi-method default is dead. Phase 2 step 5 single-method exception protocol is the structural backstop, but if the matrix itself is mis-authored the backstop never fires.

---

## Rules (NEVER list)

1. NEVER select a discipline based on the claim's intent verb in isolation. Selection is claim-type x fitness-requirement, returning a SET.
2. NEVER invoke a single discipline without a filed `SINGLE_METHOD_EXCEPTION` whose justification trigger is in the protocol's allowed list.
3. NEVER drop a discipline from a selection plan without a `CAPACITY_BOUND` or `DISCIPLINE_FAILED` ledger entry naming the deferred discipline.
4. NEVER procedurally tiebreak a contradiction. Contradictions are surfaced (Surprise Register) and inherited (S4 CONTESTED render, S6 partial-saturation-reset, S8 expansion).
5. NEVER silently re-type a claim based on a discipline's finding. Re-type candidates are written to the Surprise Register and returned to S5.
6. NEVER let disciplines see each other's intermediate state. Parallel invocation is structural, not nominal.
7. NEVER mutate Surprise Register ownership-controlled fields. The Claim-Typing Engine owns the register; the Orchestrator writes via contract.
8. NEVER cite a source in any finding that is not in the upstream fitness-verified source set. S2 bypass is integrity-breaking and halts the run.
9. NEVER drop the Research Auditor from any baseline discipline set, even under capacity pressure.
10. NEVER agree with the operator that "this question is obvious / efficient / best handled by a single method" -- that request is the failure mode RAM exists to prevent. Decline and proceed multi-method.
11. NEVER batch ledger writes to the end of the run. Write at each invocation, each return, each register write.
12. NEVER produce a synthesized claim-level finding for a CONTRADICTORY convergence class. The synthesized field is `CONTESTED`.
13. Use double hyphens (--) instead of em dashes in all output.

## Reopen Triggers

This skill's outputs cause RAM-level reopens when:
- Phase 7 Escape Hatch detects single-method collapse on any test case -> reopen Phase 1A S3 decomposition
- Phase 9 eval harness shows multi-method triangulation rate < 50% on stacked-intent test questions -> reopen Phase 1A S3
- Phase 6 smoke test shows Surprise Register entries written by Orchestrator that violate Claim-Typing Engine ownership contract -> reopen Phase 4 cross-cutting ownership protocol design
- Any run produces a Triangulation Record with discipline subset size = 1 and no SINGLE_METHOD_EXCEPTION ledger stamp -> reopen this skill's Phase 2 step 5 protocol
