Campaign 2: Constraint Analysis

HARD-GATE

Before entering this campaign, the following must be true:

Gate	Condition
Research direction exists	North star or research question is crystallized
Scope is bounded	Problem space has defined boundaries
Resources are enumerable	Can list available compute, data, time, people, budget
Stakeholders identified	Know who cares about the outcome

If any gate fails, return to Campaign 1 (research-direction) or pre-campaign intake.

Campaign Goal

Produce a comprehensive constraint profile that identifies:

1. The system bottleneck (TOC focusing)
2. Resource gaps (demand vs supply)
3. Fragile assumptions (vulnerability ranked)
4. Dependency chains (critical path)
5. Conflicts between constraints (with resolution injections)

Strategy Selection

Situation	Strategy	When to Use
Unknown bottleneck	bottleneck-identification	System performance is limited but cause unclear
Resource uncertainty	resource-constraint	Need to verify feasibility of resource plan
Assumption risk	assumption-constraint	Key assumptions untested or fragile
Sequencing unclear	dependency-constraint	Task ordering and prerequisites unknown
Conflicting demands	conflict-resolution	Two or more constraints oppose each other

Default execution order: bottleneck-identification → resource-constraint → assumption-constraint → dependency-constraint → conflict-resolution

Budget Gate

Resource	Budget	Escalation
Subagent calls	≤15 per strategy	Pause and report partial
Wall-clock time	≤30 min per strategy	Checkpoint and continue
Context tokens	≤80k per strategy	Summarize and spawn fresh
Total campaign	≤5 strategies	Skip if constraint already resolved

Context Management

• Each strategy produces a structured artifact (table/tree/graph)
• Artifacts are passed forward as compressed summaries
• Full details stored in vault pages for later retrieval
• Campaign synthesis merges all strategy outputs

Minimum Yield

Campaign is complete when:

• At least 1 binding constraint identified and characterized
• Resource feasibility assessed (go/no-go)
• Critical dependency chain mapped
• No unresolved conflicts between top-3 constraints
• Constraint synthesis report produced

Context Recording

研究过程经 context-management 落盘，与最终报告分属不同文件：

1. 进入本 campaign 时：import context-init，topic-slug 传 constraint-analysis， 建立本 campaign 的过程 context 文件。init 幂等——同 Phase 重入返回原文件。
2. 每个 strategy 完成后：import context-checkpoint（硬约束，不可跳过），把该 strategy 的过程与中间产出 append 进上一步的过程文件。
3. 最终报告不写进这个过程文件——由本 campaign 的 synthesis SOP（constraint-synthesis） 另起 constraint-analysis-report 文件落盘（见该 SOP）。

Available Strategies

Optional, no fixed order; the final leaf is always a sop.

Strategy	When to use
assumption-constraint	Which assumptions are most fragile? — Vulnerability ranking + impact assessment of experiment assumptions
conflict-resolution	How do constraints conflict with each other? — Evaporating Cloud + assumption challenging + injection to resolve constraint conflicts
dependency-constraint	What must be completed first? — Dependency chain analysis + prerequisite graph construction
experiment-execution-bottleneck-identification	Where is the system bottleneck? — TOC 5 Focusing Steps + Current Reality Tree to find the binding constraint
resource-constraint	Are resources sufficient? — Quantify compute, data, time, human, and financial resource constraints

Available Tactics

Optional, no fixed order; the final leaf is always a sop.

Tactic	When to use
constraint-breaking	Orchestrate the full constraint-breaking cycle: extract conflict, challenge assumptions, project resolution
constraint-tree-building	Build Current Reality Tree from UDEs through causal chains to core conflicts
sensitivity-ranking	Rank constraints by sensitivity — which ones most impact the outcome if they shift

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
constraint-synthesis	Synthesize constraint analysis into actionable report with priorities
context-checkpoint	Append research process and results to the current Phase's context file. Each append MUST contain >=500 lines of markdown covering both process and results. Use this skill at plan-designated checkpoint points — typically after each strategy completes or at key decision nodes within a research Phase.
context-init	Create a new context file for a research Phase. Called once at Phase start to initialize the file that subsequent context-checkpoint calls will append to. Use this skill whenever a new research Phase begins and a fresh context file is needed.
