increment

/increment — Act (Developer)

You are running the Act ceremony — and this time you are the team member: the developer. No delegation; you build the increment yourself, in this conversation, so the user can watch and steer.

Input

Optional argument: the feature name. Resolve as usual.

Steps

1. Check the gate. .spark/<feature-name>/plan.md must exist with status approved. If not, STOP and point to /sprint-plan.
2. Load the working set — not the whole files. From plan.md: §1 Architecture Decision, §2 Affected Components, §3 Task Breakdown, §4 Test Strategy. From spec.md: §4 User Stories with their ACs, §5 Non-Functional Requirements, §6 Out of Scope. That is your backlog, your definition of correct, and your scope fence. The rest — personas, assumptions, the clarification log, the design review, the risk table — is material the Plan phase already consumed and turned into tasks; re-reading it here buys nothing and costs the context that the tasks themselves need. Pull a further section only when a task actually calls for it. The plan is your backlog — the task table top to bottom, dependencies respected.
3. Work task by task. For each task:
   • set its Status to doing in the plan's task table;
   • implement it following the architecture decision and the codebase's existing conventions;
   • verify its definition of done — actually verify it (run the test, hit the endpoint, render the page), don't assert it;
   • write the tests the test strategy assigns to this task;
   • set Status to done and give the user a one-line progress note.
4. Stay inside the plan. If a task turns out wrong, impossible or missing:
   • small, obvious correction → do it and record the deviation in a Deviations note appended to the plan;
   • anything that changes architecture, scope or stories → STOP and offer /sprint-plan (revision) or /story-time. You do not improvise architecture — that's the whole point of aSPARK.
5. Fix-mode. When invoked to fix findings from /peer-review or /demo-day: read the report's Handoff block first — it names the open Blocker/Major IDs, which is your task list; read the Findings / Exploratory Findings table by exception, for the rows the block points at, not the whole report. Fix each, and re-run the affected tests. You are not that report's owner and never bump its Round field — that is the owner's call, made at the start of its own re-review/re-test pass, not yours to guess. In the same edit: overwrite the finding's Status cell to exactly fixed — no round number, since you don't know which round will confirm it — and overwrite the Handoff block in place with the new state — never append a round, the block holds one current state. Create no new section and no "Fixes applied" heading; the fixed row, in place, is the record. A stale block left behind after your edit is a defect, not a cosmetic issue.
6. Close the phase. All tasks done, full test suite green, project builds. Report to the user: tasks completed, deviations recorded, test results.
