Start work

<!-- sflow-copilot-pause -->

First require an explicit Work ID, then run singularity-flow workspace branches --entry --intake --work-id <WORK-ID> --for-agent --json once. It checks pause before Git and combines workspace/build/clean-tree/catalog facts. If paused, native Copilot; only offer /sf-pause off, never resume implicitly. Reuse the packet; no separate pause/workspace/version/status/catalog calls. Ask explicit choices; creation still revalidates live authority.

<!-- sflow-output-contract: explicit-selection -->

Output contract: Explicit choices; no preselection; preserve errors/artifacts/actions. Summarize artifacts with verified Markdown-preview links; never paste document bodies, code or diffs into Copilot. For code, list touched paths and observed added/deleted/created line counts; unavailable stays unavailable. Use existing evidence, not extra calls solely for display. Summaries, links and opened previews are not human review or approval. For every next action, honor returned commandGuidance in order: Copilot, Shell, VS Code (model-free) using modelFreeCommand; if absent, say "not available for this action". Missing Copilot: "no verified equivalent". Never invent routes.

<!-- sflow-execution-boundary -->

Boundary: no Story required; reuse entry repositoryPath after its workspace/clean-tree checks. Refuse absent/unready selections; never search $HOME/parents. Use exact CLI-returned paths. repositoryPath is command cwd, not a prefix for absolute file paths. Never rebase paths or strip .git/worktrees. Issued private/external files are exact exceptions to repository confinement, not wider read/write permission; writes still need authorization. Resolve relative paths only against their declared base. On failure, preserve the path and error; never search or recreate it.

1. Use the entry once. workspace-repair-required: follow /sf-workspace for its exact selected repository; re-enter only after repair. worktree-review-required: preserve and list its changes; do not create a Story. The person commits, ignores, moves or lands them (/sf-adhoc), then reruns /sf-start. Use its repositoryPath; never search for a checkout.
2. Unless existingWork.status is new, route existing IDs to /sf-session or singularity-flow resume <WORK-ID>, never restart. Unreachable/unknown repositories are not new IDs.
3. The catalog and selected-base preflight check required members together; no workspace-wide status rescan. Repair returned missing-member failures explicitly. Authority failure: Shell singularity-flow workspace reinitialize --dry-run --json, Copilot /sf-admin; never init for an absent local workflow file.
4. Choose <BASE> explicitly. If intake.workflowCatalogScope is not approved-configuration, run step 6 without --work-type. Choose <WORKFLOW> from exact-base intake.storyWorkflows.
5. Collect Jira/manual outcome, criteria, scope, risks, documents. References need ID, credential-free URL and branch: --reference-repository ID=URL --reference-branch ID=BRANCH. Pass --jira/--story-file; pair document inputs with their name flags. Never search for inputs.
6. Choose baseline (reuse, optional reviewed run, defer), tests (changed-and-affected, all-configured) and gates (hard, soft) separately. Soft needs exact human coverage-risk review, reason/expiry; tests/integrity stay hard. Run singularity-flow workspace branches --json --intake --preflight-story <WORK-ID> --from-branch <BASE> --work-type <WORKFLOW> --selected-base-only --mint-intake-receipt --readiness-baseline <CHOICE> --test-execution-mode <MODE> --gate-mode <GATES>. Missing tests/setup never block creation or imply a pass. No implicit installs/tests; baselines use /sf-ready. World Model/AST/models/telemetry: advisory. Never upgrade configuration here. preflight.storyBranch is the branch start creates; a person's own name goes to both as --ref <BRANCH>.
7. Start with identical base/workflow/baseline/test/gate flags; add returned --intake-receipt. targetUrl: required needs --target-url; pass a recommended one when given. Without ask_user, use step 8 or stop; keep hard gates unless explicitly selected otherwise.
8. Without ask_user, use pinned choices: singularity-flow choices begin start <WORK-ID> --for-agent --json, singularity-flow choices answer <TOKEN>, pass --selection-receipt <TOKEN> (15-minute, single-use).
9. Show readiness; /sf-next. Pending tests: Copilot /sf-test-setup; Shell singularity-flow capability test-setup --json. Tests run later; publish needs evidence.

TRP: singularity-flow explain test-recovery; acceptance needs native evidence/live human review. Never answer approval cards; use returned actions.
