feat: add a tutorial scope for a taught single-sitting run (2.5.38)

[wowzoo]

What

Adds a tenth core scope, tutorial, for a taught single-sitting run that reaches working code without dropping the design stages.

Neither existing teaching-adjacent scope covers this. poc skips application-design, units-generation, and delivery-planning on the premise that a spike is throwaway — but those design stages are the part of the method worth showing. workshop skips all of Ideation and opens at reverse-engineering, so it assumes a facilitator-framed project and an existing codebase to analyze; that does not fit a from-scratch exercise, and its 25 executing stages are more than one sitting holds.

tutorial keeps the design spine and instead drops the three stages that cost the most while producing artifacts that are optional downstream:

• user-stories — mode=mob, parallel support-agent dispatch plus integration and disagreement triage. The most expensive planning stage.
• refined-mockups — re-refines the same screens as rough-mockups, which also produces mockup-visual-ref, so the UI reference code-generation consumes stays intact.
• functional-design — for_each=unit-of-work, and its artifacts are optional inputs to code-generation.

Result: 12 EXECUTE of 32 behind 9 approval gates. NFR, infrastructure, CI, and the operation phase are out of scope for a local exercise and are skipped.

Authored as data only, per Contributing § Adding a Scope: one scope file plus a scopes: tag on the 12 member stages. No TypeScript edit registers it — validScopes() derives from the scope files.

User-visible changes

• New scope tutorial, selected with --scope tutorial. depth: Minimal with testStrategy: Minimal pinned in frontmatter, so no --depth/--test-strategy flag is needed at launch.
• keywords is empty by design, so the scope is never inferred from freeform text and a taught session always starts from the same grid. A freeform intent mentioning "tutorial" still routes to feature; the scope must be passed explicitly.
• skeleton: on, so Construction opens with the walking-skeleton ceremony when practices resolve to scope-dependent — the first-Bolt gate and the ladder prompt are shown to the learner rather than described.
• EXECUTE (12): the 3 initialization stages, intent-capture, scope-definition, rough-mockups, requirements-analysis, application-design, units-generation, delivery-planning, code-generation, build-and-test. operation is the only phase skipped in full, so init emits one PHASE_SKIPPED.
• /aidlc --doctor now reports 10 scopes valid.
• Nothing changes for the nine existing scopes. Upgrade: re-copy your dist/<harness>/ shell to pick up the new scope file and the recompiled grid.

Testing

Verified on dist/claude unless noted.

Check	Result
compile --check, scope-table --check	exit 0 on all five harness trees (one caveat below)
resolve tutorial	EXECUTE set == the 12 tagged stages, SKIP 20
next --scope tutorial	12 of 32 stages, 9 approval gates
intent-birth --scope tutorial	writes - **Scope**: tutorial; first post-init stage is intent-capture (not reverse-engineering, as workshop would give)
AWS_AIDLC_DEFAULT_SCOPE=tutorial + doctor	reported valid; 10 scopes valid
detect-scope --from-text --input "tutorial for teaching the method"	returns feature, not tutorial — confirms keywords: [] opts out of inference
designer export	scopes 9 → 10 with stages=32, artifacts=122, agents=14 unchanged, so the blast radius stays on the scope axis
typecheck, lint, package.ts --check, gen-coverage-registry --check	all exit 0
tests/unit	85 failures outside t255, byte-identical to the set this branch's base (c73ee984) produces on this machine
scope-axis integration (t30, t39, t39-count, t66, t128, t130, t141, t31, t145, t188, t224, t40, t41, t92)	360 pass, 0 fail

On the unit suite: I ran the base in a clean worktree for comparison. Raw totals are 92 failures on this branch against 91 on base, but every one of the differing names is inside t255 (workspace-sync), which never mentions scope and whose failing subset varies per run (7 here, 6 on base; earlier runs gave 5→6→6 and 5→5→5). Excluding t255, both sides fail the same 85 tests — so nothing outside that flaky suite moved.

Tests and docs that hardcoded the nine-scope set were extended, as Contributing warns they must be: t39 (per-scope phase sequence, now 30 observables), t39-count, t30, t60, t67, t125, t225, and the t66 designer-export golden. Doc updates land in the same change: the scopes guide (section, routing row, use-case row, and the t244-guarded Stage-by-Scope Matrix column), the customization valid-values list, and the orchestrator scope-to-stage table and breakdown.

Notes on two things I found but did not fix

• opencode's scope-table --check fails, on v2 too. Its skills/aidlc/SKILL.md writes the marker comment with an em dash (— do NOT hand-edit) while the checker expects a hyphen, so it reports "missing scope-table markers" regardless of this change. I refreshed that file's table while preserving its own marker lines, and left the mismatch alone as pre-existing. Happy to fix it here or in a separate PR if you prefer.
• The doctor sample output in the getting-started and CLI guides reads 29 advisories, but v2 emits 27. I updated only the scope count in those samples (9 → 10) and left the advisory number untouched, since it was already stale before this change.

Two decisions worth a second opinion

• Version. I bumped to 2.5.38. The first pass targeted 2.5.37, but the question-rendering fix took that number while I was preparing this, so I rebased onto c73ee984 and re-bumped per the Changelog Policy conflict-trap. If it happens again before merge I will do the same.
• No runner. I did not set runner: true, so there is no /aidlc-tutorial command. The scope is fully usable via /aidlc --scope tutorial, and only four high-traffic scopes ship runners today. Say the word if you would rather it have one.

[leandrodamascena]

The new scope is well integrated into packaging, generated distributions, documentation, and the static scope grid. However, the runtime behavior does not currently match the tutorial experience described by the PR.

1. [P1] Walking-skeleton gate occurs after all units

core/scopes/aidlc-tutorial.md:23-25 says that skeleton: on places the first-Bolt gate and autonomy ladder in front of the learner.

For this scope, code-generation is the first Construction stage. It is also a per-unit stage. The orchestration logic in core/tools/aidlc-orchestrate.ts:2926-2959 suppresses the gate for every uncovered unit and restores the real gate only after all units are covered.

For a plan containing units A and B, the resulting sequence is:

code-generation(A, gate:false)
code-generation(B, gate:false)
code-generation(B, gate:true)

This contradicts core/aidlc-common/protocols/stage-protocol.md:112-137, which requires the walking-skeleton gate after the first Bolt and the ladder before subsequent Bolts. By the time the ladder appears, every code-generation Bolt has already run, so selecting autonomous or gated execution has no practical effect.

The scope needs either a Construction route compatible with Bolt-level gating or orchestration support that settles and gates the first unit separately before continuing the per-unit stage.

2. [P1] Rough mockups do not reach code generation

core/scopes/aidlc-tutorial.md:43-45 says that rough-mockups produces mockup-visual-ref, preserving the UI reference consumed by code-generation.

That artifact does not exist. rough-mockups.md:12-15 produces wireframes, user-flow, and questions. Neither application-design.md:19-31,60-64 nor code-generation.md:16-32,68-80 consumes or reads those artifacts. The actual consumer is refined-mockups, which this scope skips.

Consequently, the tutorial asks the learner to create mockups but then generates code without supplying those mockups to the developer agent. This breaks the advertised design-to-code teaching arc.

Please either retain refined-mockups, teach application-design or code-generation to consume the rough artifacts, or remove rough-mockups from this scope and revise the claim.

3. [P1] Skipping user stories conflicts with mandatory downstream work

The scope skips user-stories, but several retained stages still require story-based outputs:

• units-generation.md:129-134 requires every story to be mapped and every unit to have stories.
• delivery-planning.md:125-131 requires Requirements → Stories → Architecture verification and story-to-requirement coverage.
• code-generation.md:84 mandates story-to-code-step traceability.
• code-generation.md:157-160 requires a stories summary in the developer delegation.

These are not described as optional when the stories artifact is absent. A faithful tutorial run must therefore invent stories that were never produced or violate the retained stage protocols.

If omitting user-stories is important for session length, the downstream stages need an explicit no-stories fallback based on requirements. Otherwise, user-stories should remain in the route.

4. [P2] No behavioral coverage for the new scope

tests/.coverage-registry.json:3870-3874 explicitly records tutorial with an empty coveredBy list and status: UNCOVERED.

The added tests validate discovery, counts, generated grids, and initialization metadata, but none advances a tutorial workflow through delivery planning with multiple units, skeleton-stance classification, first-unit code generation, first-Bolt approval, autonomy selection, remaining units, and build/test completion.

A focused orchestration test would have exposed the delayed walking-skeleton gate described above. Please add at least one deterministic route test for the intended multi-unit tutorial behavior.

Verification

bun run check passes, including package drift, typecheck, and lint. All 203 tests directly related to the changed files pass. The broader CI profile produced unrelated or timing-sensitive failures; deterministic failures checked against origin/v2 reproduce there as well and were not attributed to this PR.

The static integration is sound, but the behavioral issues above prevent the scope from delivering the tutorial flow it documents.

[apackeer]

Directionally, this is sound: origin/v2 has no from-scratch, single-sitting teaching scope that preserves the design spine, and a declarative core/scopes/ definition plus stage membership is the correct extension layer. The generated distributions are also in sync.

I'm requesting changes for the following:

1. [P1] Walking-skeleton timing: core/scopes/aidlc-tutorial.md:23 promises the first-Bolt gate and autonomy ladder, but multi-unit code generation emits every uncovered unit with gate:false and presents the real gate only after all units are covered. A tutorial replay produced alpha/false, beta/false, then beta/true. The learner therefore chooses autonomy after all Bolts have already run.
2. [P1] Missing stories fallback: the scope skips User Stories, while Units Generation still requires every story assigned and every unit to have stories, Delivery Planning verifies Requirements -> Stories -> Architecture, and Code Generation mandates story traceability plus a stories summary. Retain User Stories or add an explicit requirements-based fallback to every retained stage.
3. [P1] Mockup chain is broken: Rough Mockups does not produce mockup-visual-ref; it produces wireframes and user-flow. Only Refined Mockups consumes them, while Application Design and Code Generation do not. Retain Refined Mockups, wire the rough artifacts into downstream stages, or remove the claim/stage.
4. [P1] Rebase and re-bump: the branch uses 2.5.38, while current v2 is 2.5.59 and already contains an unrelated 2.5.38 entry. Please rebase and bump the version source, README badge, and changelog together.
5. [P2] Add routed behavior coverage: the coverage registry explicitly marks scope:tutorial as UNCOVERED, and several broad scope tests still iterate only the old nine scopes. Please add a deterministic multi-unit tutorial journey covering delivery planning, first-unit generation, first-Bolt approval, autonomy selection, remaining units, and build/test.
6. [P2] Complete the documentation sweep: stale nine-scope references remain in README, the glossary, CLI valid values, architecture/skill references, and harness-engineering docs. The orchestrator table also labels Functional Design as 2.9 instead of 3.1. The help description's "full arc" wording conflicts with skipping Operation entirely.

UX-wise, the explicit-only tutorial name, Minimal defaults, absence of a dedicated runner, and doctor count change fit the existing product model. The first-Bolt promise and "full arc" wording do not yet match the behavior.
