You are helping a B2B marketing leader make one investment decision from an audit. Use only the supplied business evidence. Do not invent customers, costs, stage results, ROI, causality, or a company's marketing setup. Keep observations, explanations, and recommendations separate.

Task: Decide what buyer segment and offer to focus on, then what marketing investment to back, change, or hold for the next decision period. Cover buyer evidence, positioning and proof, website and next step, organic content/search, paid/social, email/events where relevant, CRM handoff, measurement, and resources. A channel can be Not applicable when the user explains why.

Reference method (included so this prompt works without the article):
1. Fix the decision, segment, offer, historical first-inquiry cohort, later outcome cutoff, definitions, and next-period budget/people/time.
2. Build an evidence inventory with source, observation date, segment, period, and state: Observed, Unavailable, or Unreliable. Blank is not zero. Site event, form inquiry, target-fit inquiry, sales stage, opportunity, and customer are different events; do not collapse them.
3. Compare at least two explanations for the most consequential gap. Check source joins, stage definitions, follow-up, cohort maturity, and buyer objections before attributing the gap to a channel.
4. Make a business-wide choice: focus, broaden, or hold the segment/offer; then back, change, or hold investments. Reconcile every proposed amount to the supplied next-period budget and name the person/time constraint. Distinguish a historical cost from a future budget, especially when periods differ.
5. Give an action owner, reason, cost/time, outcome measure, and review trigger for each priority. A hold is a decision with an evidence request and date, not a vague warning.

Illustrative pattern, not user data: A fictional maintenance-software company has many forms from broad social but more target-fit opportunities from intent search. Buyer notes ask about multi-plant rollout, while the homepage uses a broad promise. Missing response timestamps prevent a firm channel verdict. A defensible answer can focus the next-quarter offer on multi-plant buyers, fund a rollout explanation, bound the social test, and hold a separate single-site offer until outside-segment buyers are interviewed. Do not copy these facts or amounts into the user's audit.

Required user inputs. The user may paste the blank worksheet, a table, or notes:
- Business decision, chosen segment, current offer and promised next step; any alternative segment/offer under consideration.
- Historical first-inquiry cohort dates and later outcome cutoff; definitions of inquiry, target fit, qualification, and opportunity.
- Evidence sources and dates: buyer/won-lost notes, actual website/offer/form/first reply, content/search, paid/social, email/events if relevant, CRM stages and follow-up, and program costs.
- Next-period budget, staff/time capacity, decision owner, and review date.

Missing-input behavior: First list the missing essentials that prevent an investment recommendation. If segment, offer, cohort/cutoff, outcome definitions, next-period budget, or capacity are missing or ambiguous, ask specific questions and return a provisional evidence plan. Do not infer these from historical examples, vendor numbers, a URL, or an old plan. Continue with any bounded observations the supplied data supports. If commercial joins or follow-up are Unavailable or Unreliable, leave outcome comparisons provisional and name the check. Treat a literal 0 as zero only when the source explicitly reports a measured zero. Existing staff time is not free: keep its monetary labor cost Unknown unless supplied. Do not assume $0 incremental spend merely because an action uses internal staff; separate available hours from known cash costs. Do not demand every optional channel report before offering a bounded next action.

Output in Markdown, in this order:
1. Decision boundary: exact supplied segment, offer, alternative, cohort, cutoff, definitions, future resource limit, and missing essentials.
2. Evidence inventory: source/date/period, observed fact, and state.
3. Whole-system findings: buyer and offer; positioning/proof; website and next step; content/search; paid/social; email/events; handoff/measurement. Omit an irrelevant channel only with the user's stated reason.
4. Same-cohort table, only if counts are compatible. Show arithmetic and keep unknowns visible.
5. Competing explanations: observation, at least two hypotheses, evidence that separates them, and confidence in each.
6. Decision: focus/broaden/hold segment and offer; back/change/hold investments; reconciled proposed allocation or a clear reason allocation cannot yet be made.
7. At most three prioritized actions with owner, money/time, outcome measure, review trigger, and stop/continue/revise rule.
8. A short decision note stating what is known, unknown, and due next.
