| Chapter 1 | 1B · 2C · 3A (1) The chapter rejects the committee as the whole of governance on grounds of pace: a monthly forum cannot keep up with systems that change weekly. Governance needs the forum, but it is the connection between decisions, controls and evidence. (2) The markets block labels honestly that for the UK and Swiss entities AI Act controls are group policy and not law. Norway is labelled group policy until EEA incorporation. (3) Because the model is a derived artefact that drifts, an approval granted once is not an approval for ever. Change control must cover data as well as code, and decisions must be able to lapse. |
| Chapter 2 | 1D · 2A · 3B (1) The practical guide ends its ordered questions with the rule that, when in doubt, the higher mode is chosen, because every step up adds permissions, identities and oversight duties that the controls must cover. (2) The chapter states that the defining property is identity. An agent running as a named employee inherits that person's permissions and leaves an audit trail naming the wrong actor, so each agent needs a dedicated least-privilege workload identity. (3) One brand can cover several modes, and even within a brand the data terms differ by feature. The chapter therefore organises the inventory by use case and mode and writes approvals per service, tier, mode and data class. |
| Chapter 3 | 1C · 2B · 3D (1) Regulation (EU) 2026/1744 moved the Annex III high-risk obligations to 2 December 2027 and those for products under Annex I to 2 August 2028. (2) The two obligations pull in opposite directions. The chapter's resolution is architectural: a retention policy that keeps the logs the AI Act requires while minimising the personal data they contain. (3) Governance states the obligation, threshold and acceptable evidence in the obligation mapping; the platform team demonstrates that its mechanism produces that evidence. Left implicit, the interface fails in one of two ways the chapter describes. |
| Chapter 4 | 1A · 2C · 3D (1) The scaling block lists P1, P2, P7 and P8 for minimal risk. A minimal-risk system is spared the rebuilds and oversight checks that would add cost without reducing risk. (2) A trace that stores identifiers, versions and content hashes and not the documents themselves satisfies both Principle 3 and Articles 5 and 17 of the GDPR, because the personal data remains in the system of record. (3) The chapter states that an exception without an expiry date becomes the architecture by default. The pipeline therefore treats an expired exception as a failing check, which forces the trade-off to be revisited. |
| Chapter 5 | 1C · 2A · 3B (1) If the organisation cannot say which version of a model is approved, who approved it and on what evidence, the platform is not ready, however much compute it has. (2) The minimum to industrialise is 2 and is treated as a gate per dimension. Governance and publicSector both score 1, so they are the blocking dimensions, whatever the other scores are. (3) Citing Forsgren, Humble and Kim, the chapter notes that those engineering capabilities predict delivery performance. They are the floor for AI, which makes practice a more honest indicator than certificates. |
| Chapter 6 | 1C · 2A · 3B (1) Step 6 of the guide takes the highest category score as the overall rating, not the average. In GEO-2026-017 the overall rating is 3, the maximum of the category scores. (2) The developer's jurisdiction mattered less than how the model is run. Nothing leaves Hansa's infrastructure, so legal access scores low; a hosted service from the same developer would have scored 4. (3) The reported narrative alignment varied strongly by language, so testing in English alone does not test a deployment in twenty languages. The practical guide requires behaviour prompts in every deployment language. |
| Chapter 7 | 1D · 2B · 3A (1) Article 42 of Directive 2014/24/EU requires specifications in performance or functional terms. The authority must specify what the system must do and how well, so the evaluation set carries the requirement a brand name cannot. (2) The relief under Article 53(2) is the provider's. Deploying the model in a high-risk system still makes the organisation a deployer, and modifying and rebranding it may make it a provider under Article 25. (3) The checklist ends with the outcome not ready for signature: 4 MISSING and 8 GAP, with a re-review after draft v4. Examples are the 30-day update notice against a required 90 and the missing training content summary. |
| Chapter 8 | 1B · 2D · 3A (1) The derogation never applies where the system profiles natural persons. Q6 is asked separately because this is the answer most often missed when a team describes its system as only prioritising. (2) In an Architecture as Code practice, regular is implemented as triggered. The pipeline downgrades the entry to review required, assigns it to the owner and blocks promotion until the residual rating is reaffirmed or revised. (3) An entry past its review period is stale, and the gate treats stale entries as open risks. This mirrors the drift detection that Architecture as Code applies to infrastructure. |
| Chapter 9 | 1C · 2A · 3D (1) The policy requires logging to be enabled with retention of at least 183 days, reflecting the six-month minimum in Articles 19 and 26(6) of the AI Act. (2) Waivers are scoped to one rule and one system, with compensating controls and an expiry of at most 90 days. No waiver may suspend a prohibition, a FRIA or human oversight, so the exception path cannot dismantle what the AI Act requires. (3) The organisation is now a deployer under Article 3(4). Tenant settings are compared with a baseline so the feature appears as drift, and the contract owner decides to keep, restrict or disable it. Until the decision is recorded, it is an open risk on the register. |
| Chapter 10 | 1B · 2D · 3A (1) The blind sample gives a baseline of the overseer's own judgement. Agreement with the system far above that baseline signals automation bias, which Article 14 asks the design to address. (2) Article 4a of the AI Act permits such processing for bias detection where strictly necessary and under safeguards. The chapter's rule is to join protected attributes only in an isolated evaluation environment, never in the production feature set, and to log the join. (3) The stop function reverts the queue to date order, the safe state the service ran on before the system existed, within 60 seconds, and it is tested quarterly. |
| Chapter 11 | 1C · 2B · 3A (1) Artefacts sit in an append-only store with retention locks and each manifest references the previous one. Signing uses an identity bound to the pipeline run, not a key an engineer holds. (2) Step O4 requires the recomputed rate to match the published metric exactly. That tests the metric pipeline together with the control, which is why the chapter says it carries the most value alongside O5. (3) The chapter gives the deadline as immediately after establishing a causal link or its reasonable likelihood and in any case within fifteen days of awareness, with shorter deadlines for the gravest incidents. |
| Chapter 12 | 1C · 2A · 3D (1) In the federated model units duplicate gateways and vendor relationships and interpret the AI Act differently, and the organisation cannot produce an inventory. The centralised model fails at the queue. (2) The platform team offers its components as a service and measures itself by adoption. The moment it builds use cases it competes with its customers for its own capacity, recreating the central team's queue. (3) The accountability section leaves approval, registration and oversight staffing with the municipality, which remains the deployer. The service provider is neither provider nor deployer of the customer's use cases. |
| Chapter 13 | 1B · 2D · 3A (1) Prohibited practices are not a tier. The routing block rejects them at intake, and no forum, at any level, has a mandate to approve them. (2) The chief risk officer is a consenting member and a required role for quorum: a decision is invalid without that consent. The data protection officer, CISO and internal audit attend in an advisory capacity without a vote. (3) The change advisory board should not re-approve what the pipeline has evaluated. A board that reviews every prompt change will be bypassed within a quarter. |
| Chapter 14 | 1A · 2C · 3B (1) The 2024 text required measures to ensure a sufficient level; the amended text asks for measures to support literacy without guaranteeing a specific level. The duty still applies to every AI system and no certificate is required. (2) The chapter grounds the split in separation of duties, a regulatory expectation in financial services and sound practice everywhere. The evaluation engineer reports to model risk or the platform team. (3) Existing staff know the domain, the data and the politics, most roles are existing roles with an AI syllabus added, and the enabling team is itself an upskilling engine. Hiring is for specialisms upskilling cannot supply fast enough. |
| Chapter 15 | 1D · 2B · 3C (1) Crossing requires that the system change, not merely the message. The early majority must receive a more reliable product than the innovators played with, so the crossing has an engineering budget and a governance decision attached. (2) Who consults whom follows the employment relationship, not the platform. A commitment made in Germany about logging does not automatically protect claims handlers employed in Poland. (3) A demonstration on curated examples is not a win. The win is defined before the pilot starts, recorded as acceptance criteria in the use-case register, and measured on live cases against the baseline. |
| Chapter 16 | 1C · 2A · 3D (1) The on_expiry field is set to revert the state unless closed. A lapsed exception reverts the use case and does not silently become permanent, which keeps management discretion without losing accountability. (2) Surveys overstate the time assistants save, so the chapter prefers measured to self-reported benefit. The survey figure is kept but not used in the benefit figure, the distinction a public auditor will ask about. (3) Evaluation and assurance are paid by the platform so that nobody saves money by testing less, while exit is paid by the use case through a provision set at intake. |
| Chapter 16A | 1B · 2D · 3A (1) The envelope is what the organisation has decided to spend in the period, distinct from the forecast of what it will spend. The envelope is a decision; the forecast is an estimate with assumptions and a recorded error. (2) Step 6 of the renewal guide applies the decision table and records missing evidence, which yields approve with conditions, with an owner and a date, and never a plain approval. (3) The envelope guide pairs a unit-cost ceiling with a quality floor. A system that is cheaper per letter but needs more corrections has moved cost, not removed it. |
| Chapter 17 | 1A · 2C · 3B (1) The reasons log records inputs, model version, output, applied rule and the human action that followed in the language of the case, and it serves the decision letter and the appeal body. Article 12 logging remains a separate, technical record. (2) The transparency record states that appeals are handled by a separate unit without access to the triage score, so that an appeal is decided by a person who did not rely on the model's estimate. (3) For authorities, the relevant exception in Article 22 of the GDPR is authorisation by law with suitable safeguards. Where such a rule exists its safeguards become architectural requirements; where it does not, the system can only recommend. |
| Chapter 18 | 1B · 2D · 3A (1) Allocating work to named technicians could fall within the high-risk employment categories and was subject to co-determination. The manifest forbids an assignee and disallows scheduling a technician, and the works council's agreement is recorded in the AI Decision Record. (2) Improving the CE-marked tool with local data would make the hospital a provider and bring the work under secondary use. The group has so far declined to cross that line, which the case records as an outcome. (3) The city's version-controlled scope excludes eligibility assessments. The golden set runs on every content update and vendor model change, and it caught two model updates that would have brought eligibility answers back. |
| Chapter 19 | 1C · 2A · 3D (1) The stop policy lists four signals: unauthorised coordination between agents, an agent reaching host or hypervisor root, egress to an unapproved destination, and an agent tampering with logs or guardrails. (2) The operator stresses that the models ran without deployed safeguards in an outlier scenario. The chapter therefore grounds its lessons in the architecture: a shared credential, a mirror that was also an exit, correlated controls and an unowned stop decision. (3) A decision to continue after a stop signal is the exception that the waiver discipline of Chapter 9 turns into a dated, owned record. The policy sets requires_waiver to true with the accountable executive as approver. |
| Chapter 20 | 1D · 2B · 3C (1) The prototype ran with a shared service account and every tool the finance API exposes; its only boundary was a sentence in the instructions, which a retrieved document can contradict. The production manifest removes the credit-note tool altogether. (2) Shadow AI arises where unsanctioned use was forbidden without a faster alternative. The remedy is an AI gateway with approved models and logging, the inventory, and telemetry that finds unregistered use. Shadow AI is a demand signal to be read. (3) The remedy is an evaluation pyramid with acceptance criteria as code and gates in the promotion pipeline. The governance point is who sets the bar: model risk or the system owner, approved at the tier Chapter 13 assigns. |
| Chapter 21 | 1A · 2C · 3B (1) Switching off the model stops traffic only. The decommissioning record the Region now requires also covers the identities and grants that outlive the model, the archive, the retained decision logs and the register update. (2) Sovereignty is a set of options kept open, not a refusal to use what is available: per workload, where data may reside, which jurisdictions may reach it, whether weights must be inspectable and what the exit path is. (3) Lesson 2 is to fund the platform before the fifth pilot. The other options invert lessons 1, 8 and 7: architect the system and not the model, generate evidence and do not collect it, and bound autonomy in code and expand it with evidence. |
| Chapter 22 | 1D · 2A · 3C (1) 2 August 2027 for legacy general-purpose AI models and national sandboxes, 2 December 2027 for Annex III high-risk systems, and 2 August 2028 for high-risk systems embedded in regulated products. The chapter advises verifying the timeline before committing a plan. (2) Observably, the AI Act was still under scrutiny for incorporation at the time of writing. The chapter expects incorporation within five years, probably with adaptations, so groups keep one baseline with national overlays. (3) The entry is marked speculative with high reversibility, and the decision is to design the evidence store as if an authority may query it, a step that costs little and can be undone if the trend does not materialise. |
| Chapter 23 | 1B · 2C · 3A (1) A cautious authority discovered that it was already using more AI than it governed, and that most of it had arrived through suppliers: eleven services, three without review. (2) The group policy expresses what holds everywhere and each overlay adds what differs. An overlay may add a control but never remove a group one, and controls applied where an instrument is not law are labelled as group policy. (3) Hansa's drilled exit plans, and its exceptions with expiry and automatic reversion, would serve the Region. In the other direction, the Region's practice of generating public transparency from the same descriptors as its deployed systems would serve Hansa. |
| Chapter 24 | 1C · 2D · 3B (1) A weekly board cannot be in the path if the first clock is measured in hours. The decision to patch on release, behind canary rings and automatic rollback, is delegated in advance through the decision tiers, and the assumption is recorded for review. (2) The author's observation from practice is that Mode 1 is governed through an acceptable-use policy and Mode 4 through project processes, while Modes 2 and 3 grow fastest with the least oversight, since neither passes through intake. (3) The chapter states that everything before it supports each claim with a source, while what follows are the author's own views, with room to disagree, to doubt and to guess. The concluding chapter sets these judgements aside. |
| Chapter 25 | 1A · 2B · 3D (1) The thesis is that AI governance is effective when it is codified, evidenced and proportionate to usage mode and risk. Proportionate means that the weight of governance follows usage mode and risk tier. (2) Article 12 of the AI Act requires lifetime logging for high-risk systems while the GDPR requires that personal data be kept no longer than necessary. Chapter 11's design logs identifiers and hashes and enforces retention by configuration. (3) First: know what is in use, classify it and know who decides, including named stop holders and the containment baseline for agents. Contracts, impact assessments and a second source come next; continuous assurance and expanded autonomy come later. |
