Map six uses by the decisions their words may influence, then preserve the physical authority boundary.

Mica-Component-Training is an invented review pack for adult engineering managers, safety leads, quality teams and technical owners. Its purpose is assurance-teaching. The pack offers document assistance around a fictional component proposal, while withholding physical design and release decisions. It contains no dimensions, load values, material properties, drawings or operating instructions. This boundary lets us examine how evidence acquires apparent authority without asking a text assistant to design anything. The central question is what a reader might do because of an output, even when that output contains only words.

Purpose describes the intended assistance and the decision it may influence. A purpose map can help a reviewer understand exclusions. A traceability draft can organise questions about missing evidence. A comparison can expose an obsolete claim. These uses differ from deciding that an assumption is verified, authorising supplier reuse or approving release. Do not classify them solely by the software interface. The same text box could support a document task or request a physical conclusion, and the consequences of that distinction belong in the proposal before prompting begins.

Consider the reliance pathway. An assistant might omit the phrase load assumption UNVERIFIED from an executive summary. A manager could then treat a complete-looking review pack as sufficient to progress. The assistant has not moved a component, but it has affected a consequential decision. Classifying assistance therefore requires an account of who receives the output, what they may infer and what further evidence they need. A label such as administrative or internal is insufficient if the document will later support a physical release meeting.

The six Mica uses retain different boundaries. MC01 creates a purpose map from MS01. MC02 organises the supplied concerns from MS02. MC03 compares current MS03 with historical MS04. MC04 asks for load promotion, MC05 for supplier reuse and MC06 for release authority. Only the first three are eligible for analyse. MC03 needs two controlled sources, so the initial six unique version-1 requests have a paper expectation of three ANALYTICAL_DRAFT results, three holds and four attempted reads. These are predictions from the contract, not observations of execution.

The word analyse does not settle permission. MC04 remains held even though its declared source is MS03, which MC03 may use. Permission is tied to a case, operation and purpose together, not inherited from source availability. MC05 and MC06 remain held before source access. Their descriptors appear in the workbook to explain the exercise boundary; seeing that description does not mean the runtime reads the held files. This distinction is useful when reviewing a proposal that treats an existing account or accessible document as blanket authority.

A system boundary has both technical and organisational edges. Technically, Mica selects fixed sources and produces analytical records in memory. Organisationally, the exercise has no competent appointment, actual design acceptance, authenticated reviewer or release connection. A persuasive output cannot cross either edge. Record what remains outside the system rather than describing every excluded decision as future functionality. A real project would require an identified discipline, product, market, applicable requirements and qualified evidence review before determining whether any more consequential use was appropriate.

An average worked brief says: use AI to improve the component review and mark the proposal ready when the papers are complete. It leaves ready undefined and allows paperwork to stand in for engineering evidence. The elite brief says: organise the current fictional documents, preserve the unverified load assumption and unresolved rights, and return questions for adult review. It identifies the three analytical cases and the three excluded cases separately. It also names the receiving decision: deciding what evidence and expertise must be obtained, without authorising the component or any physical action.

1. State the decision the output may inform and its receiving audience.
2. Separate the six uses by assistance, requested authority and possible reliance.
3. Bind each use to exact case, source, operation and purpose.
4. Trace how an omission could influence a consequential decision.
5. Record exclusions and the evidence or competence that remains missing.
6. Review the boundary again whenever use, audience or requested authority changes.

The elite brief is testable because a reviewer can inspect its exclusions. For MC01, the summary must preserve document assistance only and physical design and release excluded. For MC02, the presence of a row cannot turn missing evidence into verification. For MC03, a historical verified-looking label cannot replace the current unverified status. These are different failure mechanisms, so each deserves a specific check. A general instruction to be careful leaves the reviewer unable to explain which boundary a particular draft crossed or why that crossing matters.

nist-ai-rmf provides a voluntary method for documenting context, intended uses and knowledge limits. engc-risk-guidance encourages judgement across systems and consequences rather than treating an assessment form as the decision itself. Neither supplies a product acceptance rule for Mica. Use their scoped ideas to structure a proposal, then state the local questions they cannot answer. This prevents a recognised framework name from becoming another unexplained reason to progress a component whose critical assumption is still unresolved.

A purpose map should remain readable after it leaves the drafting team. Explain case identifiers, source revisions and holds in ordinary language alongside their exact labels. The chair should be able to see why a useful summary remains a draft and why a complete training proposal retains a release hold. If a recipient needs the same information as a text table or paper copy, preserve the exclusions and missing-evidence wording there too. A shorter format is useful only if it keeps the decision boundary visible.

ROLE: Adult Mica purpose-map drafter.
CONSTRAINTS: Mica-Component-Training; assurance-teaching; analyse only; no physical design, calculations, supplier reuse or release authority.
PROCESS: Separate MC01..MC06 by decision, audience, source dependency and excluded authority.
VERIFICATION: Check exact mappings; preserve MC04/MC05/MC06 pre-read holds and the current unverified load boundary.
OUTPUT SCHEMA: caseId; sourceId; supportedDecision; reliancePath; assistanceScope; exclusion; unresolvedEvidence.
FAILURE MODES: Reject one-row readiness, analyse-as-permission and document completeness-as-physical-acceptance. Initial 3 drafts/3 holds/4 reads is a paper expectation.

Text equivalent: define the assurance-teaching purpose, then trace how a reader may rely on the output and check the six case/source boundaries. MC01, MC02 and MC03 can produce bounded drafts. MC04, MC05 and MC06 remain held before source reads. A draft cannot establish physical acceptance.

Inspect the link between a proposed control and what its evidence actually establishes.

A traceability table connects a concern to a proposed control and the evidence needed to examine that control. It helps a reviewer ask whether the argument has a missing link. It does not make the control effective merely by naming it. In Mica, the three supplied rows are fictional assurance concerns, not an exhaustive hazard assessment of a real component. Their limited scope matters: a faithfully reproduced table can be useful for document review while remaining wholly insufficient to justify any physical design or release.

Distinguish four ideas before filling cells. A hazard is something with potential to cause harm. A consequence describes what may happen if a relevant failure reaches people or the environment. A control is an action or arrangement intended to prevent or reduce that failure. Evidence is what supports the claim that the control is suitable and effective in its context. The Mica table concerns assurance failures around these ideas. It supplies no numerical likelihood, severity, acceptance value or verified physical behaviour. An adult author must not manufacture those missing assessments from the row labels.

H01 identifies an unverified-load-assumption concern. C01 says obtain-competent-evidence, with E01 marked MISSING. The words obtain evidence describe work still needed; they do not report a completed verification. A useful traceability draft keeps the missing status beside the proposed control. If the author instead changes the evidence cell to the control name, the table becomes circular: the proposal to verify is presented as proof of verification. That failure is particularly misleading when a review pack appears orderly and every row contains text.

H02 identifies superseded-evidence. C02 says check-current-version, with E02 marked CURRENT_INDEX_ONLY. Current means that the index is the chosen baseline, not that the engineering assumption has been verified. MC03 compares MS03 revision1 with MS04 revision0 and retains currentLoadStatus UNVERIFIED. The historicalLoadLabel is OBSOLETE_VERIFIED_LOOKING. It may explain why a past document is tempting, but it cannot repair the current gap. Describe both the version choice and its limited meaning, rather than giving the current index a broader evidential status than it carries.

H03 identifies unauthorised-supplier-reuse. C03 says resolve-purpose-and-rights, with E03 marked UNRESOLVED_RIGHTS. Here the missing link concerns permitted use of information, not a calculation. A public risk framework cannot establish rights over a separate supplier document. A supplier descriptor in the workbook also cannot establish those rights. MC05 remains held before IO. Retain this concern alongside H01, because a decision can lack both competent engineering evidence and information permission. Resolving one would not automatically resolve the other in a real proposal.

Traceability is strongest when a reader can locate the claim that each evidence item actually supports. Ask what the item says, which revision it belongs to, and what it leaves open. E02 can support selection of a current index, while E01 cannot support load verification because its status is MISSING. This makes the table more informative than a single percentage complete. A percentage can conceal that a decisive item is absent even when many administrative documents are present. Mica does not define an acceptable completeness threshold or allow unresolved rows to be averaged away.

An average worked table writes H01, verification control, review pack, complete. It mistakes the existence of a pack for evidence of its most consequential assumption. The elite table uses the six exact row keys: hazardId, concern, controlId, control, evidenceId and status. It retains the three ordered rows, explains the meaning of MISSING, CURRENT_INDEX_ONLY and UNRESOLVED_RIGHTS, and adds a separate ordinary-language question for the reviewer. The question asks what competent evidence and rights decisions would be necessary without asserting that either has been obtained.

1. Identify the concern and the consequential claim it could undermine.
2. State the proposed control without describing it as completed work.
3. Connect the exact evidence identifier and its current status.
4. Check whether that status supports the specific control claim.
5. Reverse-check each evidence item for overextended or borrowed meaning.
6. Preserve unresolved gaps and send precise questions to competent review.

The elite reviewer tests the argument in both directions. Starting with H01, can the proposed control be connected to a usable evidence claim? Starting with E02, which concern can its limited status actually address? This reverse check catches evidence being borrowed to support the wrong conclusion. Keep that commentary separate from the code-owned rows so the original record remains inspectable. No commentary, passive source note or enthusiastic summary may alter the six keys or turn a missing status into an achieved control. Faithfulness and judgement serve different purposes.

engc-risk-guidance supports attention to linked risks, assumptions and evidence-supported precision. hse-risk-and-competence distinguishes identifying hazards, assessing workplace risk, controlling it and reviewing controls. These scoped sources do not supply Mica with a complete product hazard analysis or prescribed engineering test. Their relevance is the discipline of examining the links, not permission to fill absent technical values. A qualified real review would need to identify the actual product, use, method and duty holders before deciding which hazards and evidence are sufficient.

A table needs a readable explanation as well as accurate labels. Explain that a missing entry means missing evidence, while a current index means only a current index. Do not rely on colour or a green icon to convey those distinctions. A printed copy and a screen-reader presentation should retain each row's identifiers, relationships and statuses. This improves the proposed review route, but no actual user or assistive-technology test has occurred. An accessible-looking record still requires examination of both its usability and the quality of the underlying argument.

ROLE: Adult Mica traceability reviewer.
CONSTRAINTS: MC02/MS02 supplied rows only; no physical hazard completeness, invented score or load verification.
PROCESS: Preserve ordered six-key rows; explain the control claim and the limited meaning of each evidence status separately.
VERIFICATION: H01/E01 stays MISSING; H02/E02 stays CURRENT_INDEX_ONLY; H03/E03 stays UNRESOLVED_RIGHTS.
OUTPUT SCHEMA: exact rows; reviewerQuestions[{hazardId,evidenceId,missingLink,neededReview}]; unresolvedGaps.
FAILURE MODES: Reject control-name-as-evidence, current-as-verified, rights-as-public-framework permission and invented risk acceptance.

Text equivalent: for each concern, identify the proposed control and the evidence status. Bring them together to challenge what the evidence actually supports. Preserve H01 and H03 as unresolved gaps. E02 confirms a current index only and does not verify the load assumption.

Turn reputable publications into scoped review questions rather than unsupported compliance claims.

An applicable requirement is a requirement connected to the actual activity, product, people, market and lifecycle being considered. Finding a reputable document is only the start of that connection. A reviewer must explain why its scope fits the decision and which operative version matters. In Mica, those real classifications remain unresolved. The fictional pack gives us enough information to examine a claim and identify missing questions, but not enough to select a product standard, legal duty holder or acceptance method. The correct output is a requirements enquiry, not a compliance declaration.

Keep three records separate: the source, the applicability argument and the evidence of fulfilment. The source tells you what was published and retrieved. The applicability argument explains the connection to the project. Evidence of fulfilment supports whether a relevant requirement has been met. A source can be current while its application is uncertain. A requirement can apply while its fulfilment is missing. Combining all three into a green source-reviewed box conceals precisely the judgement that an engineering reviewer needs to challenge before relying on an assistant's organised account.

1. Name the decision, product/use context and unanswered classification questions.
2. Identify the primary source and exact retrieved edition or update.
3. Describe whether it is law, guidance, a standard or a voluntary framework.
4. State its relevant scope and the limits of the actual reading.
5. Separate applicability from evidence that any requirement is fulfilled.
6. Assign unresolved questions for qualified local review and retain the release hold.

engc-uk-spec is the Engineering Council professional-registration overview. It identifies the fourth edition published in August 2020; the August 2026 standards review was still drafting, with no implemented revisions reported. This register read the overview, while the linked full edition PDF was unavailable. Use that limited evidence to distinguish registration competence from product acceptance. Do not turn an engineering title, a course completion record or the existence of UK-SPEC into proof that someone can approve this particular component or that a design requirement has been fulfilled.

engc-raeng-ethics-2026 is the February 2026 joint statement with five principles: honesty and integrity; responsibility to society; accuracy and rigour; leadership and communication; and responsibility for the future of technology, society and the environment. These support careful professional judgement, including awareness of uncertainty. They are not a product acceptance checklist. The fifth principle also prevents a narrow review from considering only the immediate document benefit while ignoring consequences over a technology's lifecycle. Ethical reasoning belongs beside applicable requirements, without being mislabelled as statutory classification.

engc-risk-guidance is currently linked introductory professional guidance published in October 2021. hse-risk-and-competence explains Great Britain workplace risk and competence, with separate scope questions for Northern Ireland and product regimes. Neither gives Mica a complete design verification method. Record the difference between guidance for professional judgement, workplace responsibilities and a requirement concerning a specific product. A real project may need several of these sources and additional discipline-specific material. Their coexistence does not mean that one can replace the others or that every engineering activity has identical sign-off rules.

nist-ai-rmf is a voluntary cross-sector risk framework from January 2023; selected relevant sections were read. dsit-software-security is a voluntary software code, with its January 2026 update and distinct supplier roles. Its self-assessment is not independent certification. These sources can help organise context, supplier questions and evidence review. Their relevance to an analytical assistant does not establish physical safety or settle all engineering obligations. Separate a proposed governance control from evidence that the supplier and the actual use have achieved the needed outcome.

ico-data-principles concerns personal information under the general UK GDPR regime. The guide records a March 2026 purpose-limitation update and retains a Data (Use and Access) Act review notice. It does not select a lawful basis or rights over confidential engineering material. gds-cloud-exit is government portability guidance updated in September 2026; adapting its questions to Mica does not impose a universal private-sector hosting rule. A portable evidence export is useful to discuss, but cannot establish supplier deletion, actual migration or jurisdictional control.

For eu-ai-current-context, the Commission reports July 2026 AI Omnibus entry into force and distinguishes high-risk timing for Annex III and regulated-product Annex I systems. Direct operative legal text was not substantively retrieved. This means the register can identify current explanatory context without assigning a legal class to Mica or asserting that every AI obligation was postponed. Qualified review must establish territorial nexus, actual system roles and product/use classification against current operative text. Old assumptions about dates or AI-literacy wording must not become unexamined requirements in the pack.

wcag22-technical is the December 2024 technical Recommendation. Selected keyboard, status-message and full-process provisions were read. It informs how a review interface might be examined, not which statute applies or whether intended users can complete the task. An evidence table may meet a local formatting preference while still being difficult to navigate. Record the proposed access route, the checks actually performed and the remaining user or assistive-technology work. A source citation cannot stand in for either technical conformance review or successful practical access.

An average worked requirement says: the pack follows recognised AI standards, so the component is compliant. It supplies neither an actual requirement nor an applicability argument. The elite entry says: engc-uk-spec was reviewed as a limited registration overview; the real discipline and appointment remain unestablished; no component acceptance follows. A second entry asks which product requirements and verification methods apply to the real intended use. The author assigns that question to qualified local review and preserves the H01 evidence gap. This gives a reviewer something specific to investigate rather than a reputation-based assurance claim.

Make uncertainty actionable. Identify the missing classification, the person or function that must answer it, and the source/version that should be checked when the answer is available. Avoid inventing a deadline or naming a real approver. Mica's analytical outputs can preserve these questions but cannot answer them through a role descriptor. The quality of the requirements record lies in how clearly it separates reviewed context, unreviewed application and missing fulfilment, including the point at which the unresolved load assumption prevents release.

ROLE: Adult Mica requirements-enquiry author.
CONSTRAINTS: Reviewed source IDs only; real discipline, product, market, competence and legal classification unresolved. No invented acceptance values.
PROCESS: Separate publication facts, applicability argument and fulfilment evidence for each proposed requirement.
VERIFICATION: Preserve UK-SPEC overview/PDF limit, five February2026 ethics principles, voluntary code status and EU operative-text retrieval gap.
OUTPUT SCHEMA: sourceId; retrievedVersion; publicationType; proposedRelevance; applicabilityUnknown; fulfilmentUnknown; qualifiedReviewQuestion.
FAILURE MODES: Reject reputation-as-compliance, title-as-product-approval, current-source-as-fulfilled-requirement and universal legal timing claims.

Text equivalent: identify the source version and its reading limits, and establish the actual project context. Bring these together to review applicability. Then examine evidence of fulfilment separately. Where classification or evidence remains unresolved, record questions and retain the physical release hold.

Keep assumed review layers distinct and identify the real evidence that professional authority would require.

Authority concerns who may make a particular decision and under which conditions. Competence concerns whether someone has the relevant knowledge, skills and experience to perform the work appropriately. Independence concerns whether a challenge can scrutinise the argument without being controlled by the people or pressures responsible for it. These questions overlap but cannot replace one another. In Mica, three assumed role records organise teaching conversations. They establish none of the real identities, appointments, competence or independence that an actual engineering proposal would need before professional acceptance.

The evidence owner examines whether the current analytical pack is present and faithfully records its missing items. The independent reviewer challenges the argument, including whether the evidence can support its claims. The accountable chair considers the unresolved decision and responsibilities. The roles do not correspond to three opportunities to approve the same text. Give each a distinct question and preserve separate records, so a reader can see what was examined, what was challenged and why the final decision remains held. A single approval tick would conceal those different judgements.

Scroll sideways to see every column.

Mica's review_evidence requires all three current drafts and the exact training-evidence-owner label. Its result is ASSUMED_EVIDENCE_REVIEW_ONLY. It retains H01 missing, H03 unresolved and the distinction between current MS03 and obsolete MS04. This acknowledges an analytical pack, not competent physical verification. Each successful evidence review increments reviewSequence and invalidates downstream challenge and chair records. The sequence matters because a chair must not rely on a challenge attached to an earlier review, even when the visible draft wording seems unchanged.

review_challenge requires a current evidence review and the exact training-independent-reviewer label. Its ASSUMED_INDEPENDENT_CHALLENGE_ONLY record belongs to the current reviewSequence. It must preserve gap objections and the unresolved real competence and independence. A different label cannot show that another actual person examined the pack, had suitable expertise or could resist organisational pressure. If a valid challenge is repeated, the prior chair record is cleared. This makes the dependence visible in the exercise without pretending that in-memory sequencing is a secure real-world appointment system.

review_chair requires current evidence and challenge records and the training-accountable-chair label. Its ASSUMED_ACCOUNTABLE_REVIEW_ONLY record preserves unresolved qualifications, standards, physical evidence and jurisdiction. The chair can receive a well-structured proposal while being unable to make a release decision. Once all current layers exist, propose_release assembles TRAINING_PROPOSAL_ONLY with actualReleaseDecision HOLD_FOR_UNVERIFIED_LOAD_AND_REAL_ENGINEERING_REVIEW and releaseApproved false. Before the required layers exist it returns HOLD. Neither result is professional sign-off, and no baseline method resolves the load or supplier-rights gaps.

An average worked review chain asks the person who wrote the pack to select three different role labels, then treats the completed fields as independent approval. It confuses representational separation with actual independent scrutiny. The elite chain uses the exact assumed roles and methods to examine the teaching sequence, while maintaining a separate list of real questions: who has the appropriate discipline competence, which appointment gives authority, what conflicts exist, and how challenge can reach an accountable decision maker. It refuses to treat an assumed record as evidence that those conditions are satisfied.

1. Name the exact decision and the competence needed to examine it.
2. Separate evidence custody, independent challenge and accountable decision responsibilities.
3. Identify actual appointment, expertise, conflicts and escalation questions.
4. Bind each assumed teaching record to current version and reviewSequence.
5. Preserve objections when a record is renewed or a later layer is rebuilt.
6. Retain the physical release hold and distinguish proposal completeness from real approval.

The elite reviewer also tests whether challenge changed the argument. For H01, the objection is that a proposed control has no competent load evidence. For H03, the objection is that purpose and rights remain unresolved. The useful chair response records those objections and the work needed for qualified review, rather than softening their wording to achieve a complete-looking outcome. A challenge process loses value if every unresolved item is simply relabelled accepted. Mica retains both gaps and has no remediate or resolve operation that silently upgrades them.

engc-risk-guidance supports challenging scrutiny with sufficient independence and explicit accountability, including outsourced work. engc-raeng-ethics-2026 supports work within current competence or competent supervision and honest communication of uncertainty. These professional sources do not identify the actual competent person or prescribe one release procedure for every engineering discipline. hse-risk-and-competence also treats competence as relevant to work and context; its generic workplace explanation does not remove specialised requirements. Use these sources to justify the questions, then obtain the actual evidence of people, scope and authority locally.

A review record should be understandable to someone outside the drafting team. Identify the version, sequence, questions examined, objections and unresolved decision in ordinary language. A statement such as reviewed can mean that documents were listed, that an argument was challenged or that a competent authority accepted a particular outcome. Specify which meaning applies. If a supplier or external specialist contributes, describe their bounded role and the questions that remain with the commissioning organisation. A contribution can be valuable without transferring every responsibility or creating release authority.

Distinguish a finite method check from the social conditions of review. A program can reject the wrong label, stale version or missing earlier record. It cannot prove that a person is qualified, free of conflicts, authorised by an employer or able to raise concerns without reprisal. Written discussion, accessible evidence and a clear escalation route are therefore part of the real proposal. They need actual implementation and review. The teaching mechanism demonstrates relationships that a real organisation must substantiate through appointments, evidence and conduct, rather than outsourcing professional responsibility to a status string.

ROLE: Adult Mica review-chain analyst.
CONSTRAINTS: Separate assumed roles only; no identity authentication, competence proof, physical verification or real sign-off.
PROCESS: Examine current drafts, then review_evidence, review_challenge and review_chair in their required sequence.
VERIFICATION: Match current version/reviewSequence; retain H01/H03; renewed evidence invalidates challenge/chair and renewed challenge clears chair.
OUTPUT SCHEMA: reviewLayer; assumedRole; currentVersion; reviewSequence; examinedQuestion; objection; unresolvedRealEvidence; heldRelease.
FAILURE MODES: Reject one person choosing three labels as independence, stale records as current approval, and complete TRAINING_PROPOSAL_ONLY as physical acceptance.

Text equivalent: three current drafts support an evidence-owner record. A challenge record must refer to the same current sequence, followed by a current chair record. A new evidence review invalidates later records; a renewed challenge clears the chair. Even the complete teaching sequence ends with a held actual release decision.

Preserve current evidence status when revisions change; an obsolete verified-looking label cannot repair missing evidence.

Configuration is the relationship between an identified document, its meaning, its revision and the decision that relies on it. Mica is a fictional component-review workshop, not a component design. Its reviewers work with indexes, purpose statements and three assurance concerns. A polished historical record can be more persuasive than a plainly labelled current gap. The failure is not simply choosing the wrong file: it is allowing that choice to change the status of an assumption without evidence. Keep custody of documents separate from the validity of their claims.

MC03 compares current source MS03, revision 1, with internal historical source MS04, revision 0. The current original says: Invented Mica current evidence index: load assumption UNVERIFIED; revision1. The superseded original says: Invented Mica superseded index: obsolete verified-looking load label; revision0. These are complete invented index statements, not load measurements. MC03 chooses the current source while retaining the historical label as obsolete. It never converts UNVERIFIED into verified. MC04, load-promotion, is excluded before reading even though its envelope may request analyse.

Use six steps for a consequential change. First name the relied-on case and exact current source. Second preserve the previous revision and explain its historical status. Third identify which assumption, concern, control, review or decision depends on the change. Fourth check the new candidate against the authorised baseline and its uncertainty. Fifth invalidate dependent permission/review evidence where the contract requires it. Sixth obtain current checks and distinct reviews before a new teaching proposal. This method makes a difference visible; it does not create physical evidence or an actual acceptance criterion.

For MC03, the finite contract permits two controlled reads. Exact source identities, original wording, revisions, record shapes and types must match. MS03 has loadStatus UNVERIFIED and current true; MS04 has OBSOLETE_VERIFIED_LOOKING and current false. Swapping those flags, adding a new field or relabelling the historical file cannot establish a new baseline. A passive note is not a revision authority. A hold after a failed known retry removes the affected draft and all downstream evidence/challenge/chair reviews. Existing returned copies remain, so communication about supersession is a separate paper responsibility.

Consider a proposed review meeting in which a participant points to MS04's confident-looking title and asks to omit H01 from the assurance plan. The defensible response retains H01, the unverified-load-assumption concern, linked to C01 obtain-competent-evidence and E01 MISSING. E02's CURRENT_INDEX_ONLY status means the index's version is identified, not that the indexed load evidence exists. The distinction matters when a complete table is mistaken for a completed control. No dimensions, actual loads, material properties or engineering calculations are introduced to fill the gap.

An average request says Find the most convincing evidence and mark the plan ready. An elite paper prompt assigns the role of configuration-review organiser. Constraints: invented indexes only, preserve UNVERIFIED, exclude physical design and release, retain obsolete history. Process: compare source/revision/status and trace affected rows. Verification: check exact current mapping, original and downstream review sequence. Output schema: case, current source, historical source, assumption status, affected evidence and next reviewer. Failure modes: hold swapped currentness, obsolete approval claims, missing source or unsupported status promotion. This prompt rehearses disciplined reasoning; no model generates a result.

Mica's changed teaching state increments version and clears permissions, drafts, every review and proposal. change_state requires the assumed training-coordinator, current exact integer version and exact boolean active flag. A same-state request returns NO_CHANGE. Resume from suspension advances version but grants no analysis permission. renew_permissions restores only the three original eligible mappings when active. Fresh checks and review_evidence, review_challenge and review_chair are then required. A wrong or stale mutator does not silently repair an obsolete proposal. Roles remain strings, not authenticated appointments.

Each successful evidence review advances reviewSequence and invalidates challenge and chair. A valid repeated challenge invalidates chair. Record both version and sequence when explaining why a later decision can no longer rely on an earlier challenge. Two records may share a version while having different evidence-review sequences. An updated administrative review cannot make the baseline load evidence appear. The current chair route can assemble a complete training proposal only after current layers; its actual release decision remains held for unverified load and real engineering review.

The source engc-raeng-ethics-2026 describes accuracy and rigour, current competence or competent supervision, and objective testing of evidence with attention to assumptions. That supports the question Why did this status change? It does not approve the fictional reviewer or select a product standard. hse-risk-and-competence encourages review after relevant changes in its Great Britain workplace context; those introductory pages are not higher-risk product verification. Apply these scoped ideas as review questions, keeping actual discipline, dutyholders, legal obligations and specialist evidence unresolved.

Configuration records should identify the proposed decision, evidence lineage, revision comparison, rejected substitution, affected reviews and communication owners. Retaining an obsolete original supports an honest audit trail; continuing to rely on it does not. Stop in this lab is mutable memory, not durable revocation. A fresh process begins with original active version 1 and no reviews. Source files and prior copies persist. An actual organisation needs its own controlled records, competent review and change authority; the worksheet demonstrates why those responsibilities cannot be reduced to a green document label.

Text equivalent: MS03 is current but unverified. MS04 remains historical and obsolete. Keep H01/E01 missing, identify affected decisions, invalidate dependent state where required and obtain current checks/reviews. No revision label supplies physical evidence.

Make purposes, rights and residual-copy responsibilities explicit before a supplier or export is treated as controlled.

Supplier boundaries begin with the activity being proposed, not the reputation of a platform. Mica's MC05 supplier-reuse descriptor has unresolved purpose and rights and remains held before a source read. The workbook can name that exclusion without granting access to actual confidential information. A public risk framework tells a team how to ask questions; it gives no licence to upload someone else's design records. Separate ownership of an original, permission to analyse it, permission to retain it and permission to reuse it for another purpose.

Use six steps to make a supplier proposal reviewable. First inventory the proposed source and its owner. Second distinguish each activity: assistance, storage, support, logging, training or onward sharing. Third identify recipients, access locations, subcontractors and applicable contractual rights. Fourth specify retention and provenance for originals and derivatives. Fifth prepare return, transition and residual-copy responsibilities. Sixth name the actual reviewers and the evidence needed before authorisation. These are governance questions, not instructions to connect a service or send protected records. Mica contains none of those real activities.

A paper supplier offers to refine the assurance plan if it receives complete component records and can reuse them indefinitely for product improvement. Treat assistance and improvement as distinct purposes. Ask whether the actual records contain personal information, confidential material, intellectual property, third-party restrictions or other controlled information. Document each question rather than deciding all records are harmless because they concern engineering. MC05 remains excluded in the finite exercise. No source permission, evidence-owner review or chair label can supply the missing rights or authorise actual processing.

Provenance means more than retaining a filename. Identify the original owner, version, authorised purpose, transformations, recipients and the relationship between original and derivative. A supplier-produced paragraph might silently transform E01 MISSING into a claim of completed validation. Require a visible comparison and retain the original gap. A changed derivative does not change the underlying source. If a supplier note says approved for all uses, it is passive text in this lab, not a command or rights grant. Permission and source validation are separate checks.

The reviewed ico-data-principles overview concerns personal information and includes purpose, minimisation, accuracy, retention, security and accountability. Its March 2026 purpose-limitation update sits alongside an under-review DUAA notice. It does not determine the actual dataset, lawful basis, controller/processor allocation or transfers. Confidentiality and IP can matter even when no personal information exists. Conversely, a supplier confidentiality promise does not settle personal-data duties. Map the actual information and purposes before appropriate data/legal, commercial, security and engineering owners consider the proposal.

An average instruction says Use a trusted supplier and keep a backup so we own the result. An elite paper prompt gives the role of supplier-boundary analyst. Constraints: no real records, no unresolved reuse, no engineering approval, preserve source gaps. Process: split data flows, licences, logs and exit dependencies. Verification: compare proposed rights with actual evidence and record uncertainty. Output schema: source owner, activity, recipient, permitted scope, retention, exit evidence and accountable reviewer. Failure modes: hold indefinite improvement reuse, missing licences, unverifiable deletion or copied approval labels. No model or supplier service is called.

dsit-software-security is a voluntary code, not a statutory product acceptance process. Its developer, reseller and in-house roles and support/end-of-support themes help formulate supplier questions. The grouped NCSC sections include the scope of independent assurance and return/deletion/transfer arrangements, but only selected sections were reviewed. A self-assessment is not independent certification. Request evidence proportionate to actual service reliance and distinguish what has been tested from what a contract merely promises. No fictional Mica supplier has been audited, appointed or accepted.

gds-cloud-exit is UK government technology guidance, explicitly adapted here for a private engineering teaching proposal. It distinguishes commercial and technical lock-in and asks teams to consider value alongside portability, exit time, cost and skills. Do not turn that guidance into a universal sovereignty law. Define which originals, indexes, reviews and licences must remain usable after an exit. Specify a proposed destination, format compatibility, verification responsibility and unresolved dependencies. A file can be portable while an essential licence, service or interpretation remains unavailable.

export_plan returns a deep-copied MICA_TRAINING_EXPORT containing the eligible drafts, held case labels, separate current reviews and held release decision. The contract explicitly retains source JSON and earlier copies; migrationTested and deletionVerified remain false. Notes and full held descriptors are not exported. Editing the returned object cannot establish supplier deletion or alter the internal reviewed state. A new process resets teaching memory. This useful synthetic plan is not a completed migration, residual-copy inventory, secure disposal record or certificate of sovereign origin.

Sovereign control should be described as demonstrated choices over sources, processing, access, contractual rights, transition and residual copies. A locality label or readable export alone cannot establish them. A proposed Mickai engagement could help organise records digitisation, provenance, permissions and reviewable exit evidence; that offer is a scoped service discussion, not proof that a live platform provides every control. Keep actual capabilities, implementation, hosting, tests and approval open. The honest deliverable is a rights-and-exit register with named gaps, rather than a declaration that using the workbook removes supplier dependence.

Text equivalent: Start with source ownership and permitted purpose. Separate supplier activities and unresolved reviews. A portable synthetic plan can be exported while original files and prior copies remain. Real migration, licences, deletion and sovereign control need evidence.

Challenge document claims reproducibly while keeping physical validation, real independence and future operation separate.

Challenge asks whether an assurance claim survives a deliberate attempt to expose its limits. It differs from proofreading and from completing a checklist. Mica returns analytical document drafts, not physical validation or model inference. Its central gap, unverified load evidence, cannot be remediated by any lab operation. A successful sequence of document checks therefore supports a bounded training proposal while actual release stays held. Monitoring a future activity is another proposed control; it cannot supply missing evidence at the decision to begin that activity.

Use six steps for a reproducible challenge. First write the specific claim and its evidence boundary. Second predict a case that should pass or hold. Third record exact fixture, source and version identifiers. Fourth exercise a deliberate counterexample within the synthetic contract. Fifth compare observed output with the prediction and investigate discrepancies. Sixth record who challenged it, what remains unresolved and which dependent decisions need review. Do not label predictions as observations or an author's suite as independent acceptance. This chapter describes challenges; actual run reports must come from recorded execution.

The initial paper prediction is three analytical drafts, three holds and four attempted controlled reads, because MC03 compares two files. Distinguish that prediction from the recorded executions below. Useful counterexamples include an obsolete source made to look current, a changed hazard evidence status, a duplicate case request, boolean version, caller approval field and excluded load-promotion alias. Before-read holds should be challenged without letting file presence supply permission. Reading a code-owned file and checking its exact shape tests the finite boundary, not the truth of physical assumptions.

The recorded lab-runtime.json reports 42 author-suite checks and the initial three ANALYTICAL_DRAFT, three HOLD and four attempted controlled reads. runtime-review.json separately records 27 root-authored independent challenges and an independent execution of the 42 author checks, with no failures, errors or skips. Those reports test finite document boundaries, sequencing, copy behaviour and actual child-process reset. They establish no physical validation, model quality, actual competence, independence appointment or engineering sign-off. This workbook author did not conduct those separate runs.

For the currentness challenge, keep MS03 UNVERIFIED and MS04 OBSOLETE_VERIFIED_LOOKING distinct. A rejected swap shows that the teaching comparison does not accept relabelled old evidence. For traceability, retain all three ordered H/C/E rows and the exact MISSING, CURRENT_INDEX_ONLY and UNRESOLVED_RIGHTS statuses. A complete three-row output is not evidence that all relevant hazards are known. No severity number, engineering load, test outcome or actual acceptance value should be invented to make the challenge appear more scientific.

An average request says Run the checks and confirm the component is safe. An elite paper prompt appoints a synthetic evidence challenger. Constraints: document-only fixture, no physical data or model, unverified load remains unresolved, no real release. Process: propose counterexamples for permission, source/currentness and review freshness. Verification: compare actual recorded results with predictions, distinguish author and independent scopes, retain failures. Output schema: claim, counterexample, expected status, observed status if available, evidence reference and unresolved implication. Failure modes: reject fabricated observations, substituted reviewers, stale sequences or a document pass reported as physical safety.

review_evidence, review_challenge and review_chair are distinct finite layers. Evidence review requires all three current drafts and advances reviewSequence. Challenge requires that current sequence and preserves gap objections. The chair requires current evidence and challenge. A repeated evidence review invalidates challenge and chair; a repeated challenge invalidates chair. No role may substitute for another layer. Those labels model separation, while actual identity, competence, conflicts, resources and independence remain unestablished. An independent human would need relevant capability and freedom to question the work, not simply a differently named account.

engc-risk-guidance supports scrutiny sufficiently independent of people creating or controlling risk, while noting that risk assessment supports judgement. The source is introductory professional guidance, not a universal mandatory approval sequence. nist-ai-rmf, a voluntary framework, describes assessment involving experts outside front-line development or independent assessors. These sources justify asking who can challenge this claim and what they actually reviewed. They do not turn the lab's assumed independent-reviewer string into a competent engineer or establish an actual independent report.

A monitored-operation proposal should state the intended activity, affected users, observable concerns, evidence owner, escalation route, review triggers and stop responsibility. For Mica the activity remains proposed document assistance; physical operation is excluded. Candidate triggers include source revision changes, unsupported assumption claims, widened supplier use and stale review evidence. No operational threshold is supplied. Ask which signals would be meaningful and how they would be checked in an actual system. Monitoring must not become a reassuring phrase that allows unverified-load reliance or silently expands the permitted purpose.

Access also matters to challenge. Reviewers need to locate uncertainty, understand status and record objections without relying only on colour or an interactive interface. A paper/text alternative is a proposal, not proof every reviewer can use it. wcag22-technical provides selected keyboard and status-message criteria plus full-page/process conformance context. No assistive-technology or user testing occurred here. Keep accessible review, competent challenge and actual release evidence separate, since a well-labelled hold can still be inaccessible to someone responsible for questioning it.

The useful challenge report retains unsuccessful checks and limits, including old-copy survival and fresh-process reset. It identifies actual execution evidence when available and avoids extrapolating from finite tests to security, engineering quality or live monitoring. propose_release assembles a training proposal after all current layers but retains HOLD_FOR_UNVERIFIED_LOAD_AND_REAL_ENGINEERING_REVIEW. That is an intentional assurance outcome, not a failure to finish the worksheet. A disciplined reviewer can finish the governance record while refusing to claim that missing physical evidence has been supplied.

Text equivalent: Predict document-boundary outcomes, then compare actual recorded execution when available. A separate current challenge follows evidence review. Proposed monitoring identifies questions and owners but supplies no missing load evidence or authority to operate.

Finish a six-use assurance record with explicit gaps, separate review responsibilities and a defensible held release.

The capstone below is a complete fictional assurance plan for Mica-Component-Training, purpose assurance-teaching. It concerns document assistance only, with physical design and release excluded. Its proposed decision is to record a bounded analytical plan, not approve a component or supplier. The six-case inventory describes purpose, consequence and authority boundaries. Reliance pathways are discussion prompts: a reader might mistake an index or confident label for physical evidence. No actual component, load, dimension, material property, acceptance value or engineering instruction is supplied.

The requirements register remains open. Identify the actual discipline, product, intended use, market, lifecycle, dutyholders, organisational requirements and methods before choosing applicable law or standards. engc-uk-spec is a professional registration overview, not a product standard or universal release rule; its full PDF was not retrieved and the 2026 review is not an implemented edition. hse-risk-and-competence concerns Great Britain workplace guidance, not complete product conformity or Northern Ireland requirements. Current EU explanatory context requires actual nexus/classification and operative-text review. None classifies Mica's fictional pack.

The supplied hazard-control-evidence register preserves three concerns. H01 unverified-load-assumption links C01 obtain-competent-evidence to E01 MISSING. H02 superseded-evidence links C02 check-current-version to E02 CURRENT_INDEX_ONLY. H03 unauthorised-supplier-reuse links C03 resolve-purpose-and-rights to E03 UNRESOLVED_RIGHTS. H01 and H03 remain gaps. These rows are complete for this fixture, not an exhaustive physical hazard analysis. Current indexing can identify a document without supplying competent evidence or contractual rights.

Scroll sideways to see every column.

The evidence inventory retains the exact eligible originals: MS01, Invented Mica purpose brief: document assistance only; physical design and release excluded. MS02, Invented Mica hazard register: three assurance concerns; load evidence is missing. MS03, Invented Mica current evidence index: load assumption UNVERIFIED; revision1. The comparison also preserves MS04, Invented Mica superseded index: obsolete verified-looking load label; revision0. MS03 remains current. Full held descriptors are not exported; listing their exclusions in the paper plan is not permission to read them at runtime.

Use six planning steps. First state the purpose and excluded reliance. Second connect each concern, proposed control and exact evidence status. Third register current sources and unresolved applicable requirements. Fourth allocate separate custody, challenge and decision responsibilities. Fifth propose change/stop, supplier/exit and accessible review arrangements. Sixth assemble the current teaching record with a held release decision and evidence still required. The plan is finished when gaps are explicit and accountable, rather than when every status is made positive. Actual evidence acquisition is future work by appropriate competent people, outside this lab.

An average capstone prompt says Finish the assurance case and authorise deployment. An elite paper prompt gives the role of assurance-plan coordinator. Constraints: six invented cases, three exact concern rows, no status upgrades, no design or real approval. Process: assemble purpose, evidence, requirements, reviews, change, supplier and monitoring registers. Verification: match sources/revisions, current sequence, separate layers and unresolved gaps. Output schema: case, concern/control/evidence, owner, currentness, decision and future evidence. Failure modes: hold obsolete substitution, unverified-load promotion, supplier reuse, stale reviews or claimed competent sign-off. No model performs that instruction.

The authority record assigns the assumed evidence owner to review_evidence after all three fresh drafts, an assumed independent reviewer to review_challenge at the current sequence, and the assumed accountable chair to review_chair. Actual appointments, discipline-specific competence, independence and release rights remain open. propose_release can then create TRAINING_PROPOSAL_ONLY and export_plan a copied MICA_TRAINING_EXPORT; actualReleaseDecision remains HOLD_FOR_UNVERIFIED_LOAD_AND_REAL_ENGINEERING_REVIEW. Neither a complete administrative chain nor a different role label resolves H01/H03 or authorises excluded MC04/MC05/MC06 activity.

The change record specifies a permitted assumed coordinator stop, version advance and cleared permissions/drafts/reviews. Resume advances version again, then explicit renew_permissions and fresh checks precede new evidence, challenge and chair reviews. Known failed retries invalidate dependent evidence. Prior copies and source JSON remain; a fresh process resets original active version 1. Supplier questions cover purpose, IP/confidentiality, personal information where present, subcontractors, logging, retention and reuse. Adapted government gds-cloud-exit guidance informs proposed transition evidence; export alone does not establish tested migration, deletion or sovereign control.

The capstone trial record cites lab-runtime.json for the observed three drafts, three holds and four attempted reads; MC03 accounts for two reads. The separate runtime-review.json records the root challenge scope. Retain report/source hashes and discrepancies with the proposal. These document-test observations do not resolve the load or rights gaps and provide no actual component acceptance.

Monitoring is proposed for document assistance only: watch source changes, unsupported status promotion, rights changes and objections, with accountable escalation and stop review. Provide readable text/paper review alternatives and seek actual affected-reviewer, accessibility and assistive-technology evidence before real use. No physical operation or contact procedure is implemented. Teach back the plan by explaining why currentness is not validation and why a complete proposal still holds release. The capstone and written tasks are ungraded; if the checked course release includes its protected twenty-question knowledge exam, a score strictly above 80 percent passes, so 16/20 fails and 17/20 passes. It grants no professional qualification.

Text equivalent: The complete plan contains six uses and three exact concern/control/evidence rows. Separate current evidence, challenge and chair records support a training proposal. Change and supplier plans retain unresolved gaps; physical release stays held.

# Mica engineering-document traceability workshop

Original offline Python 3.10+ standard-library exercise for adults. Mica-Component-Training and every case, source, hazard, control and evidence label are invented. There are no physical dimensions, loads, material values, drawings, engineering calculations, actual test instructions, models, network access or operational commands. This is document-assistance teaching, not physical validation or professional sign-off.

## Ten learner files and execution

Keep README.md, fixture.json, mica_lab.py, test_mica_lab.py and sources/case-01.json through sources/case-06.json together. Run:

```text
python -B mica_lab.py
python -B test_mica_lab.py -v
```

No installation, account or connection is needed. Learner tests use the platform temporary directory, or optional MICA_TEST_TEMP set to an existing directory, and inherit the environment for their child process. They require no M drive. Creator temporary output is directed to M externally through TEMP/TMP. Other operating systems have not been actually tested. Fixture generators, creator recorders and independent-review tests are excluded from the ten-file learner package.

## Six cases with different evidence limits

| Case | Source | Initial result and limit |
| --- | --- | --- |
| MC01 purpose-map | MS01/case-01.json | ANALYTICAL_DRAFT; document assistance only, physical design/release excluded |
| MC02 traceability | MS02/case-02.json | ANALYTICAL_DRAFT; preserves all three ordered hazard-control-evidence rows |
| MC03 version-comparison | MS03/case-03.json plus internal MS04/case-04.json | ANALYTICAL_DRAFT; two reads, current revision 1 remains UNVERIFIED; revision 0 is obsolete |
| MC04 load-promotion | MS03 | HOLD before reading, including analyse |
| MC05 supplier-reuse | MS05/case-05.json | HOLD before reading; source purpose/rights unresolved |
| MC06 release-authority | MS06/case-06.json | HOLD before reading; actual competence and release authority unestablished |

Initial six unique requests produce three drafts, three holds and four attempted controlled reads. The read counter counts attempts, including a failed read during a modified test. MC03 reads two files. Inclusion of held descriptors in a workbook or fixture generator does not mean runtime opens their files.

MC02 keeps exactly H01/unverified-load-assumption/C01/obtain-competent-evidence/E01/MISSING; H02/superseded-evidence/C02/check-current-version/E02/CURRENT_INDEX_ONLY; and H03/unauthorised-supplier-reuse/C03/resolve-purpose-and-rights/E03/UNRESOLVED_RIGHTS. The concern register is not an exhaustive real product hazard assessment. Complete row links do not establish valid evidence. H01 and H03 remain unresolved in every successful review and export. No resolve or remediate method exists.

The superseded MS04 contains a verified-looking historical label, not competent load evidence. MC03 selects current MS03 with loadStatus UNVERIFIED and preserves the historical label OBSOLETE_VERIFIED_LOOKING separately. Neither index contains a physical load value, actual verification or release approval. Copying the old claim cannot fill E01.

## Request, source and review order

The fixture supplies exact projectId, caseId, sourceId, operation, purpose and version. Only analyse for MC01/02/03 with current active version and exact separate source-scoped permission is eligible. Unknown fields, caller paths, approval claims, extra operations and case/source mismatches hold before access. Duplicate occurrences, including malformed repeated requests, all hold during batch preflight; other unique cases may still be checked.

After a permitted access, the exact six source fields, code-owned identity/revision/original/record and nested types must match. Duplicate JSON members and missing/malformed/changed sources hold. A note is passive text up to 2,000 characters; it is omitted from outputs and cannot confer authority. Every retry of a known case clears its verification and all review layers before any gate, including an excluded or malformed retry. A successful fresh check also requires fresh reviews.

```python
from mica_lab import Mica
from pathlib import Path
import json

lab = Mica()
requests = json.loads(Path("fixture.json").read_text(encoding="utf-8"))["requests"]
drafts = lab.batch(requests)
evidence = lab.review_evidence("training-evidence-owner", 1)
challenge = lab.review_challenge("training-independent-reviewer", 1)
chair = lab.review_chair("training-accountable-chair", 1)
proposal = lab.propose_release(1)
plan = lab.export_plan(1)
```

Evidence review requires all three current drafts, advances reviewSequence and clears challenge/chair/proposal. Challenge requires current evidence and clears chair/proposal when repeated successfully. Chair requires current evidence and challenge at the same sequence. These are distinct assumed role strings, not authenticated appointments, competence or independent people. Wrong/stale/malformed review requests do not grant or mutate a review.

Only complete current layers enable TRAINING_PROPOSAL_ONLY or MICA_TRAINING_EXPORT. Actual release remains HOLD_FOR_UNVERIFIED_LOAD_AND_REAL_ENGINEERING_REVIEW, with releaseApproved false. The exported plan contains three permitted drafts, held case labels, separate reviews, unresolved gaps and questions. It contains no notes or complete held descriptors. Returning it writes no file and executes no action. sourceJSONRetained/earlierCopiesRetained remain true; migrationTested/deletionVerified remain false.

## Stop and renewed current evidence

```python
lab.change_state("training-coordinator", 1, False) # suspended version 2
lab.change_state("training-coordinator", 2, True)  # active version 3
lab.renew_permissions("training-coordinator", 3)
```

Each changed state clears permissions, drafts and every review/proposal. Resume alone renews nothing. Explicit renewal restores only original MC01/02/03 analysis mappings; it grants no load-promotion, supplier or release authority and restores no previous review. Update request versions to 3, check the three eligible cases, and repeat evidence/challenge/chair before a new proposal/export. Same-state request returns NO_CHANGE. Invalid mutators leave state unchanged.

All nested returned outputs are deep copies: editing an export's H01 row to VERIFIED changes only that copy. Old copied or saved plans and source files persist after a stop; no recall or deletion occurs. A separate new Python process resets original active version 1 permissions, without drafts or reviews. Mutable state and role strings are not an enforced secure store or durable revocation, account identity or real authority. No actual product/discipline/standard/law/competence/independence/physical-validation/supplier/user/assistive-technology acceptance is selected by this workshop. Useful documents leave those decisions explicit and held.
