15000x · 04 — Durable templates creation (workflow + file)

Gate-toggle pattern (durable variant)

BEGIN;
UPDATE dot_config SET value='true'  WHERE key='iu_core.composer_enabled';
-- compose + mark + generate instance + record lineage
UPDATE dot_config SET value='false' WHERE key='iu_core.composer_enabled';
COMMIT;

Gate back to false post-COMMIT, compositions durable. Extends [[feedback-in-tx-gate-toggle-reversibility]] from rehearsal to durable productization.

Template 1 — workflow (tpl:wf:onboarding/v1)

5 step pieces minted (role=body):

order	canonical_address	title
0	iu_core/template/15000x/wf-onboarding-v1/step-0-d0-account	Day-0 — Account provisioning
1	iu_core/template/15000x/wf-onboarding-v1/step-1-d1-repo	Day-1 — Repository access
2	iu_core/template/15000x/wf-onboarding-v1/step-2-d2-walkthrough	Day-2 — Codebase walkthrough
3	iu_core/template/15000x/wf-onboarding-v1/step-3-d3-first-pr	Day-3 — First small PR
4	iu_core/template/15000x/wf-onboarding-v1/step-4-d5-retro	Day-5 — Retro check-in

Result: collection_id=62c032aa-8a58-44aa-b490-b236b28a7997, pieces_minted=5, pieces_attached=5.

Template 2 — file (tpl:file:status-report/v1)

5 role pieces — full role vocab:

role	section_type	title
title	heading	Status report (template)
intro	paragraph	Reporting period overview
body	paragraph	Key deliveries
appendix	appendix	Risks + open questions
reference	appendix	Linked tickets + docs

Result: collection_id=eebeb9a1-7628-4197-97b5-2018231be683, pieces_minted=5, pieces_attached=5.

Mark both as templates

Both calls returned {status:"ok", is_template:true, was_template_before:false}.

Post-state

SELECT collection_key, instance_count FROM v_iu_product_template ORDER BY collection_key;
-- tpl:file:status-report/v1 | 0
-- tpl:wf:onboarding/v1      | 1
