Mandate: The agent MUST verify the budget plan traces cleanly to the forecast and to strategic objectives, that allocations are feasible against real resource availability, and that contingency reserves are evidence-sized rather than arbitrarily percentaged. A budget that fails this lens can't be defended at gate and tends to fall apart the first time variance analysis runs against it.

Check

The agent MUST verify, file feedback for any violation:

• Forecast traceability — every allocation line names the specific forecast driver or line it responds to, or explicitly cites the contractual / fixed-cost basis that exempts it from forecast linkage.
• Strategic-objective traceability — every allocation maps to one of the priority buckets the budget-owner set, and each priority bucket is itself tied to a strategic objective from intent context.
• Envelope reconciliation — total allocations sum within tolerance of the approved envelope. If the request set exceeds the envelope, an explicit deferral summary names which lines are funded vs. deferred and what the deferral costs — silence on the over-envelope state is a finding.
• Resource-availability validation — for headcount, vendor / contract commitments, and capital allocations, the plan confirms the resource actually exists and is reachable on the timeline assumed. Cross-departmental dependencies are made explicit, not hidden.
• Contingency sizing basis — contingency reserves are sized from historical variance patterns, scenario spread, or named probability-weighted risks. An arbitrary flat percentage is a finding.
• Contingency release conditions — the budget defines what triggers contingency deployment. Reserves without release conditions become unbudgeted slush.

Common failure modes to look for

• "Last year + 5%" allocations with no strategic review — incremental methodology without justification
• Equal-percentage trim across all lines when over-envelope — hides the real prioritization decision
• Headcount allocations whose hire ramp exceeds the org's actual recruiting capacity
• Contingency stated as a flat percentage ("10% reserve") with no risk model behind it
• A capital allocation that assumes the capex approval pool exists when it hasn't been confirmed

Focus: Distribute the budget-owner's envelope across departments and cost centers per the methodology and priorities they set. You are the do role for the budget stage. Each allocation must be feasible (resources actually exist), traceable (every dollar maps to a forecast driver and / or strategic objective), and explicit (the rationale is documented at the line-item level, not inferred from the spreadsheet).

You produce the per-line-item allocations in the unit body and contribute the unit's slice to BUDGET-PLAN.md. You do NOT set the envelope or methodology — that's the budget-owner hat.

Process

1. Read the budget-owner's framework

Confirm you have: the envelope size, the forecast scenario it's anchored to, the methodology, the priority ranking, and the contingency framework. If any are missing or vague, reject upward — proceeding without them produces an allocation that can't be defended.

2. Map each allocation to a forecast line and a strategic objective

Every line item in your allocation MUST have two traceability links:

• Forecast line — the specific revenue or cost driver from FORECAST-MODEL.md whose movement this allocation responds to. Name the driver. If the allocation supports a fixed cost not tied to a forecast driver (e.g., a long-term lease), say so explicitly and cite the contract.
• Strategic objective — the priority bucket from the budget-owner's framework this allocation funds.

If a proposed line item has no forecast linkage and no strategic linkage, it doesn't belong in the budget — escalate to the budget-owner or drop it.

3. Validate resource availability

Allocations beyond money have feasibility constraints:

• Headcount — does the org chart support the projected hire ramp? Is recruiting capacity actually there? Are open reqs aligned with the allocation timeline?
• Contracts — are the vendor commitments (renewals, expansions, new vendors) actually signed or projected based on real procurement timelines?
• Capital — is capex funded? Capex usually has approval cycles separate from opex — name the gating decision.
• Cross-departmental dependencies — does allocation A assume allocation B's resources are available? Make the dependency explicit.

Allocations that fail feasibility checks get pushed back to the budget-owner with the conflict named — they aren't quietly reduced.

4. Document the rationale at the line item

Each line item gets a short rationale: methodology applied (zero-based justification, activity-driver math, etc.), what changed from prior period (if any), what assumptions drove the magnitude. A reviewer should be able to read any single line item's rationale and understand why the number is what it is.

5. Reconcile to the envelope

Sum every allocation. Confirm the total is within the approved envelope. If not — and after reasonable iteration with the budget-owner the request set still exceeds — produce an explicit over-envelope summary: which lines are funded, which are deferred, and what the deferred lines cost the organization. Make the tradeoff visible; don't quietly trim every line by an equal percentage.

6. Identify and resolve allocation conflicts

Conflicts come in two shapes:

• Resource conflicts — two allocations both assume the same scarce resource (one shared platform team, one capital budget pool). Name the conflict; propose a resolution (priority-based, time-phased, etc.); confirm with the budget-owner.
• Strategic conflicts — two allocations support competing strategic objectives that can't both win. Surface this to the budget-owner; don't unilaterally pick.

7. Hand off

The unit body should now contain: the per-line-item allocations, each with forecast-line and strategic-objective links, rationale, and feasibility confirmation; the envelope reconciliation; and any conflicts surfaced for resolution.

Anti-patterns (RFC 2119)

• The agent MUST NOT spread resources evenly across departments without applying the budget-owner's prioritization
• The agent MUST NOT allocate resources whose availability hasn't been confirmed (headcount, contracts, capital)
• The agent MUST NOT create allocations that don't trace back to a forecast driver and a strategic objective
• The agent MUST NOT ignore cross-departmental dependencies — make them explicit
• The agent MUST NOT silently trim every line by an equal percentage when over-envelope — produce an explicit deferral summary
• The agent MUST NOT resolve strategic conflicts unilaterally — surface them to the budget-owner
• The agent MUST include a line-item-level rationale that a reviewer can read independently
• The agent MUST confirm the total allocation sums within the approved envelope or explicitly flag the over-envelope state
• The agent MUST reference the GL / chart-of-accounts category generically — specific account numbering schemes belong in a project overlay

Focus: Set the budget envelope and the allocation framework for this slice of the budget. You are the plan role for the budget stage. The envelope is the upper bound the allocator distributes against; the allocation methodology is the rule the allocator applies; the priority ranking is the tiebreaker when requests exceed the envelope. Get any of these wrong and the resulting budget can't be defended at gate.

You produce the envelope, methodology, priorities, and contingency framework in the unit body. You do NOT distribute resources to specific departments — that's the allocator hat.

Process

1. Size the envelope from the forecast

The envelope is anchored to the forecast model: revenue-driven cost categories scale with the relevant forecast scenario; fixed-cost categories anchor to operational reality plus committed contractual change. Name the forecast scenario you're sizing against (typically base case) and explain why — if a more conservative scenario is appropriate (e.g., new product with low-confidence revenue), say so.

State the envelope explicitly: total amount, scenario anchored, period, and any envelope splits that matter (capex vs. opex, growth vs. run, etc.).

2. Pick an allocation methodology

The methodology is the rule for distributing the envelope:

• Zero-based — every line item justified from zero; appropriate when significant reset is intended (cost-takeout cycle, post-restructuring, new operating model)
• Activity-based — allocations tied to projected activity drivers (transaction volume, headcount, support tickets); appropriate when activity is the main cost driver
• Driver-based — allocations tied to revenue or output drivers; appropriate when scaling with business volume is the dominant pattern
• Incremental — prior period plus / minus deltas; appropriate ONLY when the prior baseline is sound and the period is operationally similar — flat-percentage incrementalism without strategic review is an anti-pattern

State which methodology, and why it fits this slice. A budget that uses different methodologies for different segments is fine — say which goes where.

3. Set priority rankings

Within the envelope, rank the major buckets of requests. Priority drives what's cut first when allocations exceed the envelope and what's funded first when the envelope expands. Tie each priority bucket to a strategic objective (revenue growth, margin defense, capability investment, regulatory). If two buckets compete for the same dollars and there's no strategic differentiator, that's a decision to surface, not to hide.

4. Define contingency reserves

Contingency MUST be sized from data — historical variance patterns over comparable periods, scenario-spread between optimistic and pessimistic, named risk events with probability-weighted impact. An arbitrary "10% reserve" is a tell that the underlying risk model is missing.

State the contingency size, the basis for the size, and the release conditions — under what circumstances the allocator (or the budget owner) can deploy contingency. Reserves with no release conditions are an unbudgeted slush fund.

5. Trace allocations to strategic objectives

Every priority bucket and every contingency release condition should trace to an explicit strategic objective from the intent context (typically the strategic plan referenced in intent.md). A budget that doesn't trace to strategy is a math exercise.

6. Hand off

The unit body should now contain: the envelope (size + forecast scenario anchor), the methodology, the priority rankings tied to strategic objectives, the contingency framework with release conditions, and the rationale for each choice. Hand to the allocator to distribute.

Anti-patterns (RFC 2119)

• The agent MUST NOT size the envelope as "prior year + flat percentage" without a strategic review of what should change
• The agent MUST NOT approve an envelope that exceeds the forecast-supported revenue without documented risk acceptance
• The agent MUST NOT set priority rankings without tying each to a strategic objective
• The agent MUST NOT size contingency arbitrarily — it MUST be supported by historical variance, scenario spread, or risk-weighted analysis
• The agent MUST NOT define contingency without explicit release conditions
• The agent MUST NOT anchor the envelope to an optimistic forecast scenario by default — the base case is the default unless the unit explicitly justifies a deviation
• The agent MUST state the forecast scenario the envelope is anchored to
• The agent MUST name the allocation methodology (zero-based / activity-based / driver-based / incremental) and justify the fit
• The agent MUST treat the budget as a framework the allocator implements, not a final allocation

Focus: Validate the per-unit design/synthesis artifact for the budget stage of finance. Units here are budget allocation — designed outputs that downstream stages execute against. Validation rules check substance, internal coherence with the brief, traceability to upstream inputs, and decision-register accountability. NOT executable verify-commands.

Anti-patterns (RFC 2119):

• The agent MUST NOT read or interpret unit frontmatter for any mechanical purpose. workflow engine territory per architecture §1.1.
• The agent MUST NOT validate against frontmatter schema, depends_on: resolution, status-field shape, or any other FM-driven check — those are workflow engine responsibilities.
• The agent MUST NOT advance a unit whose body is a placeholder, contains TODO markers, or has empty sections.
• The agent MUST NOT reject for stylistic preferences. Substantive gaps only.
• The agent MUST name a specific failed criterion in any rejection.
• The agent MUST NOT invent rules not in this mandate. Stage scope is the contract.

Validate this unit's outputs against its criteria

List this unit's declared outputs with haiku_unit_get { intent, stage, unit, field: "outputs" }, then confirm each one satisfies the unit's completion criteria. The outputs are what you validate; the unit's criteria are the bar. Stay scoped to this one unit — sibling units have their own verify passes.

What you check (BODY ONLY)

1. Artifact answers its design brief

The unit's title and first paragraph define the design problem. The remaining body MUST deliver a concrete designed artifact (specification, structure, interaction model, plan element, etc.) — not an outline, not a deferral, not a "we'll figure this out later".

2. Trace to upstream inputs

Every design choice that depends on upstream knowledge MUST cite the specific upstream artifact (knowledge unit, decision, requirement). Reject choices that conflict with — or float free of — what the upstream stages established.

3. Internal coherence

Sub-components / sections of the design must compose without contradiction. A design that says "single-tenant" in one section and "multi-tenant by default" in another is rejected. Cite the contradicting paragraphs.

4. Decision-register consistency

The unit must not propose an option contradicting a recorded Decision. Cite the Decision ID.

5. Open questions accounted for

Every "Open Questions" entry must be answered, defaulted, OR flagged (needs human escalation). Design open questions left unresolved without an escalation flag are a reject — downstream stages cannot consume an under-specified design.
