SETC Runtime Manifest

eduKateEcosystem/0070 · Singapore English Tuition Centre · ENGLISH_LANGUAGE_EXAMINATION_SPECIALIST

Singapore English Tuition Centre (SETC) is the English language, learning, teaching, assessment and performance specialist within the eduKate learning ecosystem. The English Atlas maps the territory, How English Works explains the deep language system, and the English Learning Library routes readers into skills, stages, practice and support. Examination and local-service routes apply this system; they do not define its full scope.

Canonical conceptual map: English Atlas — the public ontology connecting language structure, communicative modes, skills, reasoning, learning, teaching, assessment and performance. Use the English Learning Library for learner routing and How English Works for the deep language-system owner.

Canonical multilingual/mediation owner: Multilingual English & Mediation — translation, paraphrase, summary, synthesis, plurilingual competence, cross-linguistic transfer, interaction and meaning across languages/media.

Current interpretation: the tables dated 17 September 2026 are earlier snapshots. Read them alongside the later canonical graph and the current SETC Future Master Publish register; earlier wording must not override a later explicit ownership or routing decision. Established machine identifiers and historical check dates are retained for reference. Completion of the constitutional P0/P1 owner queue is a bounded publishing milestone, not proof that every owner, application, reciprocal link, practice resource or learner outcome has passed review. Record saved-content, public-render, route and learning-evidence checks separately.

  distinguish English specialist diagnosis from whole-learner ownership
  return bounded evidence to the originating owner
  preserve current SETC canonical English owners

MUST_NOT:
  absorb the whole learner

RETURN_OR_CALL:
  ORCHARD = unresolved owner or cross-site route
  EDUKATESG = broad research systems or HELP
  SENGKANG = live learner runtime teaching transfer verification
  SINGAPORE = wider canonical knowledge library and learning manuals
  BTT = bounded Mathematics specialist work
  PUNGGOL = Punggol-local family route tuition intake or teaching delivery

SETC_OWNS:
  English language system
  English skill specialist work
  English examination performance

BOUNDARY:
  English specialist result != whole learner ownership
  English specialist result != local tuition ownership
  cross-site return_owner is required

SETC stays first-class by being precise about what it owns. When an English specialist job is complete, the result returns to the learner, knowledge, local-delivery or research owner that initiated it.

- DOWNSTREAM_TASKS
- NEIGHBOUR_LINKS
- EVIDENCE_STANDARD
- VOLATILITY_CLASS
- REVIEW_TRIGGER
- TRANSFER_OUTCOME

VOLATILITY_CLASS:
- FOUNDATIONAL = stable mechanism; review for scholarship and clarity
- USAGE = changing convention/register; periodic review
- INSTITUTIONAL = syllabus/examination/rule; verify against official source when specification changes
- FAST_MOVING = AI/platform/emerging usage; frequent dated review

OWNERSHIP_RULES:
1. One strongest canonical owner per substantial concept wherever possible.
2. Application pages explain the concept in a stage, examination, genre, domain, location or learner state and link to the owner.
3. Directory pages route; they do not recreate owner content.
4. Singapore/local/commercial discovery pages feed the world-facing English system; they do not redefine it.
5. Do not create a new broad root when an existing owner can carry the concept.
6. Search wording strengthens the true owner; search demand must not reshape the educational ontology.
7. Internal links must express a relationship: prerequisite, mechanism, application, advanced route, practice, official rule or recovery.
8. Runtime/prototype/control documents remain public-readable where useful but NOINDEX unless explicitly promoted to reader-facing ownership.
9. The front door remains the approved ten-route concierge; do not add a competing homepage door without explicit redesign approval.
10. A repair is not proven until it survives delay, variation, reduced support and fresh-task transfer.
11. When a full owner is promoted, remove that territory from the missing-owner queue and re-route applications to it.
12. Federation handoffs outrank domain expansion: do not duplicate another eduKate specialist estate.
13. Historical explanation must distinguish evidence, reconstruction, convention and myth.
14. Usage claims such as common, formal, regional, historical, preferred or exam-required must be backed by the matching evidence class.
15. AI-assisted publication must preserve source verification, authorship, privacy, owner boundaries and independent learner transfer.
16. Canonical system owners are not complete until their own content depth, reciprocal links and transfer/release evidence match the Atlas role assigned to them.

- Build to canonical-owner depth before indexing as a new root.
- Major owner standard: definitions, mechanisms, distinctions, worked examples, diagnosis, transfer, evidence, FAQs/routes and durable internal linking.
- New owner must link upward to English Atlas and sideways to How English Works + English Learning Library.
- Existing applications must be re-routed to the promoted owner after publication.
- Do not duplicate a territory because a high-volume keyword exists.

FEDERATION_RULES:
1. Specialist sites do not become stronger by reproducing one another.
2. Link across the boundary when the reader's controlling question changes.
3. Preserve one strongest owner for the deep concept.
4. Use local, stage, career, vocabulary and examination pages as applications or routers unless explicitly designated as canonical owners.
5. Orchard/eduKateAI routes and returns; it does not become a competing subject owner.
6. When Mathematics becomes the controlling problem, hand to BTT; when English becomes the controlling problem, return to SETC.
7. Sengkang owns learner-state diagnosis/progression; Yishun owns recovery/rebuilding; SETC owns the English mechanism being diagnosed or repaired.
8. Public school/curriculum/reference discovery may route through eduKateSingapore without duplicating SETC's deep English owners.

LEGACY_CLASSIC_FREEFORM_EXCEPTION:
- Do not full-rewrite a proven classic/freeform page merely to add a backlink.
- If block-level surgery is unsafe, preserve the child body and make the canonical owner link downward to the child.
- Add the child-to-owner link only when a substantive upgrade or safe migration justifies touching the page.
- This exception protects live article quality and obeys REUSE -> REPAIR -> REFRESH -> DEEPEN -> CONNECT -> BUILD.

PROTECTED_CLASSIC_FREEFORM_LEFT_UNCHANGED:
- JC1 What to Read for General Paper WP14094 | block surgery unsafe; owner/downward routing preferred.
- Communication Plan Writing WP19509 | block surgery unsafe; preserve proven body.

FEDERATION_BOUNDARY:
SETC may retain English-form applications for CV/resume/cover-letter/job-description writing, but broader career/adult ownership remains eduKateSG Career & Adulthood.

NEXT:
- Continue child-application route audit by owner family.
- Prefer safe breadcrumb/owner-route insertions over rewrites.
- Protect classic/freeform pages unless substantive migration is already justified.

Operating rule: stay within SETC while the controlling question is specialist English language, learning, teaching, assessment or performance. Use the registered specialist or application route when the question changes to another subject, learner-wide support, recovery, family context or adult/workplace application. Preserve the originating owner and return the bounded English result. An information request must not automatically become tuition intake.
