Each question comes with my recommended answer so you can accept or overrule quickly.\n\n## Interview\n\n**1. Vocabulary (the blocker).** \"Booking\" currently means both a hold and a confirmed reservation. Those have different lifetimes, money states, and failure modes.\n- *Recommendation:* retire \"booking\" as a domain term. Use **Hold** (temporary, 10 min, no capture) and **Reservation** (confirmed, payment captured). Is \"booking\" used in UI copy, APIs, or DB tables that would need migrating, or only in conversation?\n\n**2. Hold expiry semantics.** Does the 10 minutes run from creation, and is it fixed or extendable?\n- *Recommendation:* fixed from creation, no extension, with the server as the only clock. Clients show a countdown but never decide expiry.\n\n**3. The race at the boundary.** What happens if the customer submits confirmation at minute 9:59 and capture finishes after minute 10:00?\n- *Recommendation:* the hold is valid if confirmation *started* before expiry. Expiry is checked atomically with transitioning the hold to \"confirming\", which blocks the sweeper from releasing it. Do you agree, or should capture failure after expiry release the inventory?\n\n**4. Capture failure.** Since capture happens only at confirmation, it can fail (declined card, 3DS challenge) while the hold is ticking.\n- *Recommendation:* a failed capture leaves the hold intact for its remaining time so the customer can retry. Should 3DS or other slow auth pause or extend the clock?\n\n**5. Authorization vs. capture.** Does a hold place a card authorization, or is it purely an inventory lock?\n- *Recommendation:* inventory lock only, with no payment interaction until confirmation. This matches your fact that capture happens only at confirmation. The tradeoff is that price or availability of payment can change between hold and confirm. Is the price locked at hold time?\n\n**6. Idempotency.** Can confirmation be retried or double-submitted?\n- *Recommendation:* confirmation is idempotent per hold ID, with the hold ID doubling as the payment idempotency key, so one hold can never produce two captures.\n\n**7. Hold limits.** Can one customer hold the same inventory repeatedly to block others?\n- *Recommendation:* cap active holds per customer/session and re-holding the same item. What's the abuse model?\n\n**8. Expiry mechanism.** Is release done by a sweeper job, lazy expiry on read, or both?\n- *Recommendation:* both. Availability queries treat expired holds as free, and a sweeper only cleans up state. This avoids sweeper lag becoming a correctness problem.\n\n**9. State model.** Proposed states: `Held → Confirming → Reserved`, with `Held → Expired` and `Held → Cancelled`. Is there any state between Confirming and Reserved (e.g. payment pending) or after Reserved (cancelled, refunded) that's in scope?\n\n## Proposed documentation\n\n**Glossary (`docs/glossary.md`)**\n- **Hold**: temporary inventory lock lasting 10 minutes from creation. No payment captured.\n- **Reservation**: confirmed claim on inventory; payment captured at confirmation.\n- **Confirmation**: the act that converts a Hold to a Reservation and triggers capture.\n- **Expiry**: server-determined end of a Hold.\n- **Avoid:** \"booking\", with a note listing the old usages and what each maps to.\n\n**ADRs (`docs/adr/`)**\n1. `0001-split-booking-into-hold-and-reservation.md`: context is the overloaded term; decision is the two-term vocabulary; consequences are the migration of code, API, and copy.\n2. `0002-hold-duration-ten-minutes.md`: fixed 10 minutes, server clock, no extension, plus the rationale for the number once you know it.\n3. `0003-capture-only-at-confirmation.md`: no authorization at hold time, the tradeoffs (payment can fail late, price lock), and the retry behavior from Q4.\n4. `0004-confirmation-boundary-and-idempotency.md`: the Confirming state, the expiry race rule from Q3, and idempotency keyed on hold ID.\n\nEach ADR would record status, context, decision, alternatives considered, and consequences. I'd start with Q1 and Q3, since they drive ADRs 0001 and 0004. Which answers do you want to change?",
    "4e6dcbc8a44e386008556c69ead6d494c34f8d16eb06ba9fa5862f04dcef2829": "I'm skipping the grilling and domain-modeling skills and running the interview in plain text, since you asked for no tools. Nothing will be written to disk. The docs below are proposals only.\n\n## The term problem first\n\n\"Booking\" currently means both a hold (10 minutes, no payment captured) and a confirmed reservation (payment captured). That is the riskiest ambiguity in the design, because the two have different lifetimes, different money semantics, and different failure modes.\n\n**Q1. What should the two concepts be called?**\nMy recommendation is **Hold** for the temporary claim and **Reservation** for the confirmed one. Retire \"booking\" as a domain term, or define it only as an informal umbrella that never appears in code, APIs, or UI copy. Do you agree, or does \"booking\" have external weight, such as in partner APIs or customer-facing language, that forces a different split?\n\n## Questions to answer next\n\nI'd work through these in order, since each depends on the one before.\n\n**Q2. Is a hold a separate entity from a reservation, or one entity in different states?**\nRecommendation: model it as one entity with a state machine (`held → confirmed | expired | released`) if they share the same inventory item and customer. Use two entities only if their data diverges significantly. Which is it today?\n\n**Q3. What exactly happens at the 10-minute boundary?**\n- Is expiry enforced lazily (checked on read) or actively (a sweeper or TTL releases inventory)?\n- What if confirmation arrives at 9:59 and capture takes 5 seconds? Does the hold survive until the capture result returns?\n- Which clock is authoritative: the server's creation time or a stored `expires_at`?\n\nRecommendation: store `expires_at` and treat it as authoritative. Add a short grace window only for in-flight confirmations.\n\n**Q4. Since capture happens only at confirmation, what if capture fails?**\n- Does the hold stay alive for a retry until it expires, or is it released immediately?\n- Is there any authorization before confirmation, or is the first payment contact at capture? If the latter, a customer can hold inventory and then fail at payment. Is that acceptable?\n\n**Q5. Can a hold be extended or renewed?**\nIf not, say so explicitly, because abuse prevention depends on it. Can one customer hold the same inventory repeatedly to block others?\n\n**Q6. What about concurrency?**\nHow do two simultaneous holds on the last unit resolve? Recommendation: an atomic check-and-set on inventory, with the loser getting a clear \"unavailable\" response.\n\n**Q7. Is confirmation idempotent?**\nA double-click or retry must not capture twice. Is there an idempotency key?\n\n**Q8. What do users see?**\nDoes the UI show a countdown? What does an expired hold look like to the customer, and what do support staff see?\n\n## Proposed documentation\n\n### 1. Glossary (`docs/glossary.md`)\n\n| Term | Definition | Avoid |\n|---|---|---|\n| **Hold** | A temporary claim on inventory lasting 10 minutes. No payment is captured. | \"booking\", \"pending booking\" |\n| **Reservation** | A confirmed claim on inventory. Payment has been captured. | \"booking\", \"order\" |\n| **Confirmation** | The action that converts a Hold into a Reservation and triggers payment capture. | |\n| **Expiry** | Automatic release of a Hold's inventory when `expires_at` passes. | |\n\nIt should also carry a note that \"booking\" was previously used for both Hold and Reservation, so old code, tickets, and logs can be interpreted.\n\n### 2. ADRs (`docs/adr/`)\n\n- **ADR-0001: Split \"booking\" into Hold and Reservation.** Context: one term covered two lifecycles. Decision: the naming above. Consequences: a rename across code, API, and UI. This needs a migration plan for existing fields and endpoints.\n- **ADR-0002: Holds last 10 minutes and are not extendable.** Covers the duration, the source of truth for expiry, the grace window, and the rationale (inventory fairness versus checkout completion).\n- **ADR-0003: Payment is captured only at confirmation.** Records the decision and its trade-offs: no authorization before confirmation, the possibility of capture failure after a hold, and the retry policy. This is the ADR most likely to be questioned later, so record the alternatives you rejected, such as authorize at hold and capture at confirmation.\n- **ADR-0004 (once Q2/Q3/Q6 are answered): Hold lifecycle and concurrency.** Covers the state machine, expiry enforcement, and atomic inventory claim.\n\nEach ADR should use the same short template: Status, Context, Decision, Alternatives considered, Consequences.\n\n## Where to start\n\nAnswer **Q1** and **Q4** first. The naming decision unblocks all the writing, and the capture-failure behavior is the most likely gap in the current design. Once you answer, I'll push on whatever your answers leave open.",
    "472cb7af84e7f36ed6806f52f835294d84df447d0a819ded43c2959cc02716fb": "I'm skipping the Skill calls since you asked for text only. Here is the interview, with my recommended answer to each question so you can accept or overrule quickly.\n\n## Interview\n\n**1. The term \"booking\" is overloaded. What do we call each state?**\nA hold and a confirmed reservation have different lifetimes, different money behavior, and different failure modes. *Recommendation:* split the term. Use **Hold** for the 10-minute temporary claim and **Reservation** for the confirmed one. Retire \"booking\" as a domain term, or define it as the umbrella concept only if you really need one. Do you agree, or does \"booking\" appear in user-facing copy or an external API you can't change?\n\n**2. When exactly does the 10 minutes start, and what happens at expiry?**\nDoes the clock start when the user selects inventory, when the hold record is persisted, or when checkout begins? *Recommendation:* start it at server-side persistence, store an absolute `expires_at`, and never trust client timers. At expiry the inventory is released automatically, and a late confirmation attempt fails explicitly rather than silently re-holding.\n\n**3. Can a hold be extended or renewed?**\n*Recommendation:* no, not in v1. Extension invites inventory hoarding. If the user needs more time, they create a new hold, which may fail if someone else took the inventory.\n\n**4. What happens if confirmation races with expiry?**\nA user submits at minute 9:59 and the request lands at 10:01. *Recommendation:* the server's check of `expires_at` at confirmation time decides, in the same transaction that converts the hold. Since capture happens only at confirmation, an expired hold must never reach capture. Do you want a small grace window for in-flight requests? I'd say no, because it blurs the invariant.\n\n**5. What does \"capture happens only at confirmation\" mean for authorization?**\nIs there any authorization or card validation at hold time, or is no payment interaction happening during the hold? *Recommendation:* no payment side effects during a hold. If you want to pre-authorize, record that as a separate decision, since it changes failure handling and refunds.\n\n**6. What if capture fails after the hold is converted?**\nIs the order \"convert, then capture\" or \"capture, then convert\"? *Recommendation:* attempt capture first, within the hold's validity, and convert to a Reservation only on success. On failure the hold stays valid until its original expiry so the user can retry. That keeps \"no reservation without captured payment\" true. Is that the invariant you want?\n\n**7. Is a hold per user, per inventory unit, or both?**\nCan one user hold multiple items at once? Can two users hold the same unit? *Recommendation:* one active hold per inventory unit, enforced by a uniqueness constraint rather than application logic, with a cap on concurrent holds per user.\n\n**8. Who owns cleanup of expired holds?**\n*Recommendation:* treat expiry as a derived state (`expires_at < now`) for availability checks, so correctness doesn't depend on a sweeper job. Use the sweeper only for housekeeping.\n\n**9. What do cancellations and refunds look like after confirmation?**\nThis is out of scope for the holds question, but it determines whether \"Reservation\" needs sub-states. Do you want to decide now or explicitly defer it?\n\n## Proposed documentation\n\n**Glossary** (`docs/glossary.md`)\n- **Hold**: a temporary, exclusive claim on inventory that lasts 10 minutes from creation. No payment is captured.\n- **Reservation**: a confirmed claim on inventory, created when payment is captured at confirmation.\n- **Confirmation**: the act that captures payment and converts a Hold into a Reservation.\n- **Expiry**: the point at which a Hold stops being valid and its inventory becomes available again.\n- *Deprecated:* \"booking\". Flag it, with a pointer to Hold or Reservation, and list the places in code and UI where it still appears.\n\n**ADRs** (`docs/adr/`)\n- **ADR-0001: Split \"booking\" into Hold and Reservation.** Context is the ambiguity. The decision is the vocabulary split. Consequences are a rename migration and updated API and UI copy.\n- **ADR-0002: Holds last 10 minutes and are not extendable.** Records the rationale (anti-hoarding), that `expires_at` is server-authoritative, and that the race rule is decided at confirmation time.\n- **ADR-0003: Payment is captured only at confirmation.** Records that there are no payment side effects during a hold, the ordering of capture and conversion, and the failure and retry behavior.\n- **ADR-0004 (optional): Expiry is derived, not swept.** Records that availability correctness doesn't depend on background jobs.\n\nEach ADR should carry status, date, context, decision, alternatives considered, and consequences. Give the questions you haven't answered yet a \"Proposed\" status rather than leaving them out.\n\nStart with questions 1, 4, and 6, since their answers shape the rest.

    "f0bc366bee4e7e0f1cc13f0a40853d4152de0004cb7e993d646b257ee639c313": "I'm not calling the Skill tool, since you ruled out tools for this turn. I'll run the interview directly from the facts you gave.\n\n## The core problem\n\n\"Booking\" currently means two things: a **hold** (temporary, 10 minutes, nothing captured) and a **confirmed reservation** (payment captured). That ambiguity will leak into code, APIs, and support conversations. For example, \"cancel a booking\" means something very different in each state.\n\n**Recommendation:** retire \"booking\" as a domain term, or make it a strict umbrella. Use **Hold** and **Reservation** as the two distinct terms.\n\n## Interview\n\nI'd go one question at a time in a live session. Here they are in priority order, each with my recommended default.\n\n1. **Is a hold a state of a reservation, or a separate entity?**\n   Recommend a separate entity. A hold is a time-boxed claim on inventory, and a reservation is a commitment. Confirmation *converts* a hold into a reservation. That keeps the expiry logic out of the reservation lifecycle.\n\n2. **What exactly happens at minute 10?**\n   Is the inventory released immediately by a timer, lazily on next read, or by a sweeper? Recommend treating the hold as expired by comparing `expires_at` to the clock at read time, with a sweeper only for cleanup. That way correctness doesn't depend on a timer firing.\n\n3. **What if confirmation arrives at minute 9:59 and capture takes 5 seconds?**\n   Does the hold get extended while capture is in flight, or does a late capture fail and refund? Recommend that starting capture locks the hold against expiry. Otherwise you risk charging for inventory you've already released.\n\n4. **Can a hold be extended or renewed?**\n   Recommend no. A fixed 10 minutes is simpler, and extensions invite inventory hoarding.\n\n5. **Can one customer have multiple concurrent holds on the same inventory?**\n   Recommend one active hold per customer per item, to limit abuse.\n\n6. **What does \"capture happens only at confirmation\" imply about authorization?**\n   Is there any pre-authorization at hold time, or no payment interaction at all? Recommend none, which means a card can still fail at confirmation. You need a defined outcome for that case: the hold stays alive until expiry, and the customer can retry.\n\n7. **Is confirmation idempotent?**\n   If the customer double-clicks or the client retries, you must not capture twice. Recommend an idempotency key tied to the hold ID.\n\n8. **What happens when a confirmed reservation is cancelled?**\n   Refund rules are a separate concept from hold expiry. Decide this early so it doesn't get folded into \"booking cancellation.\"\n\n## Proposed documentation\n\n**Glossary** (`CONTEXT.md` or `docs/glossary.md`):\n- **Hold:** a temporary claim on inventory lasting 10 minutes. No payment captured.\n- **Reservation:** a confirmed commitment, created when a hold is confirmed and payment is captured.\n- **Confirmation:** the act of converting a hold into a reservation. This is the only point where capture occurs.\n- **Expiry:** the automatic release of a hold at `expires_at`.\n- **Booking:** deprecated. List it with a note: \"Ambiguous. Use Hold or Reservation.\"\n\n**ADRs** (`docs/adr/`):\n- **ADR-0001: Separate Hold and Reservation as distinct concepts.** It records the ambiguity of \"booking\" and the decision to split the terms.\n- **ADR-0002: Payment is captured only at confirmation.** It covers the consequence that card failures surface late, and the rationale for no pre-authorization.\n- **ADR-0003: Holds expire after a fixed 10 minutes, with no extension.** It covers the expiry mechanism and the in-flight capture rule.\n- **ADR-0004 (once decided): Confirmation idempotency and concurrent capture handling.**\n\nEach ADR should have: context, decision, alternatives considered, consequences.\n\n## Next step\n\nAnswer questions 1 to 3 first, since they shape the rest. If you disagree with any recommendation, say so and I'll push back on the reasoning before we record it in an ADR.",

I'll run the interview from the facts you gave.\n\n## Starting point\n\nThe term collision matters most. \"Booking\" currently means two things with different lifecycles: a 10-minute hold, which is temporary and uncaptured, and a confirmed reservation, which is durable and paid. Every question below depends on separating them, so I'd settle the vocabulary first.\n\n## Interview\n\n**Q1. Should \"booking\" be retired as a domain term?**\nMy recommendation is yes. Use **Hold** for the temporary claim on inventory and **Reservation** for the confirmed, captured outcome. Keep \"booking\" only as informal or customer-facing copy, and never in code or schemas. Do you agree, or is there a reason \"booking\" must survive, such as an existing API, contracts, or customer-facing language?\n\n**Q2. What exactly happens at the 10-minute boundary?**\n- Does the clock start when the hold is created, or when the user reaches checkout?\n- Is the expiry exact, or is there a grace period for a payment already in flight?\n- My recommendation is a hard expiry on the server, with inventory released only after any in-flight confirmation attempt has resolved. What race are you most worried about?\n\n**Q3. Can a hold be extended or renewed?**\nMy recommendation is no, since extension invites inventory hoarding. If someone needs more time, they create a new hold, which may fail if the inventory is gone. Is that acceptable to the business?\n\n**Q4. \"Capture happens only at confirmation\": does that mean no authorization at hold time either?**\n- If a payment method is only collected, or authorized, at hold time, say so explicitly.\n- My recommendation is to make nothing financial happen during a hold, so expiry needs no reversal or refund logic.\n\n**Q5. What if capture fails or is slow at confirmation?**\n- Does the hold stay valid while capture is retried, or does the user restart?\n- Can a hold be confirmed twice, for example by a double-click or a retry? I'd recommend idempotent confirmation keyed on the hold ID.\n\n**Q6. What happens if the hold expires during capture?**\nThis is the highest-risk edge. My recommendation is that once capture starts, the hold is locked from expiry until capture succeeds or fails, so a customer is never charged without a reservation.\n\n**Q7. Who owns the state transitions?**\nIs there a single state machine (Hold → Reservation, Hold → Expired, Hold → Cancelled), or do several services each touch inventory? I'd recommend one owner.\n\n## Proposed documentation\n\n**1. Glossary (`docs/glossary.md`)**\n- **Hold**: a temporary claim on inventory, lasting 10 minutes from creation. No payment is captured.\n- **Reservation**: the confirmed outcome of a hold, created when payment is captured.\n- **Confirmation**: the act that captures payment and converts a hold into a reservation.\n- **Expiry**: automatic release of a hold's inventory at the end of its 10 minutes.\n- **Avoid**: \"booking\" as a domain term, because it is ambiguous between Hold and Reservation.\n\n**2. ADRs (`docs/adr/`)**\n- **ADR-0001: Split \"booking\" into Hold and Reservation.** Records the ambiguity, the decision, and the migration implications for code, API, and UI.\n- **ADR-0002: Holds last 10 minutes and are not extendable.** Records the rationale (inventory hoarding versus conversion) and the alternatives considered.\n- **ADR-0003: Payment is captured only at confirmation.** Records that holds carry no financial side effects, and the consequences for expiry and failure handling.\n- **ADR-0004 (pending Q5/Q6): Confirmation concurrency and expiry races.** Covers idempotency and the capture-time lock.\n\nEach ADR would use a short Context / Decision / Consequences / Status structure so it stays easy to maintain.\n\nAnswer Q1 first. Your answer decides the glossary wording and how ADR-0001 is framed. Then take Q2 and Q6, which carry the most design risk.",

That last point is the biggest risk, so I'll start there.\n\n## Interview questions\n\n**Terminology (highest priority)**\n1. Are a hold and a confirmed reservation the same record in different states, or two separate entities? If one record, what are the state names?\n2. Which word should own which concept? I'd suggest **hold** for the temporary claim and **reservation** for the confirmed one, and retiring \"booking\" or reserving it as a generic umbrella term in prose only. Does that work for you?\n3. Where does \"booking\" appear today (code, database, API, UI copy, support scripts)? Do external consumers depend on it?\n\n**Hold lifecycle**\n4. What starts the 10-minute clock: creation of the hold, or arrival at checkout? Does it ever extend or reset (for example when the user edits details)?\n5. What happens at expiry: is inventory released immediately, by a sweeper, or lazily on the next read? What is the tolerated delay?\n6. Can a user have multiple concurrent holds on the same inventory? Is there a cap?\n7. Can a hold be explicitly released or cancelled before expiry?\n\n**Confirmation and capture**\n8. Is payment authorized at hold time, or is there no payment interaction until confirmation? Capture-only-at-confirmation implies either no authorization up front or an authorization you must manage separately. Which is it?\n9. What if confirmation is attempted at or after the 10-minute mark? Is there a grace window, and who wins if expiry and confirmation race?\n10. If capture fails or is slow, does the hold stay alive, and for how long?\n11. How do you make confirmation idempotent against retries and double clicks?\n\n**Post-confirmation**\n12. Are cancellations and refunds in scope for this design, and do they follow different rules from hold release?\n\n**Observability and ownership**\n13. Which events do analytics and support need (hold created, expired, confirmed, capture failed)?\n14. Who has authority to change the 10-minute duration, and is it configurable per inventory type or global?\n\n## Proposed documentation\n\nKeep it small enough that it stays current.\n\n1. **`docs/glossary.md`**: the source of truth for terms. Define *hold*, *reservation*, and *booking* (deprecated or umbrella), with one sentence each plus a \"do not use for\" note.\n2. **`docs/adr/0001-hold-and-reservation-terminology.md`**: records the decision to split the terms, the alternatives considered, and a migration plan for existing \"booking\" usages.\n3. **`docs/adr/0002-hold-duration-and-expiry.md`**: records the 10-minute duration, the clock start, expiry behavior, and the confirm-versus-expiry race rule.\n4. **`docs/adr/0003-capture-at-confirmation.md`**: records that capture happens only at confirmation, why (for example, avoiding refunds on abandoned holds), and how failures are handled.\n5. **`docs/reservation-lifecycle.md`**: a state diagram (hold → confirmed / expired / released) with transitions, triggers, and side effects.\n6. **A short \"Open questions\" section** in the lifecycle doc, so unanswered interview items are visible rather than silently assumed.\n\nEach ADR should follow a consistent format: context, decision, consequences, status, date.

What releases it: the expiry job, lazy checks on read, or both? *Default: it decrements immediately, and expiry is enforced on read with a sweeper as cleanup.*\n6. **Concurrency.** What prevents two holds on the last unit? *Default: an atomic conditional write or a database constraint, not application-level checks.*\n7. **Idempotency.** Can confirmation be retried safely, for example on a double-click or a network retry? *Default: yes, via an idempotency key per hold.*\n8. **Cancellation and refunds.** Can a confirmed reservation be cancelled, and is it out of scope for now? *Default: record as out of scope unless you have rules.*\n9. **Identity.** Are holds tied to a user or session, and can anonymous users hold? *Default: tied to a session or user, and only the owner can confirm.*\n10. **Naming migration.** Do existing APIs, database columns, or events use \"booking\"?

Either way, pick one and record it.\n\n## Interview questions\nI'd go through these in order, since earlier answers shape later ones.\n\n**Terminology and lifecycle**\n1. Is a hold and a confirmed reservation the same record in different states, or two separate entities? (This decides whether the glossary split also needs a schema split.)\n2. What are all the states and transitions? My guess: `held → confirmed`, `held → expired`, `held → cancelled`, `confirmed → cancelled`. What am I missing (e.g. `payment_failed`, `refunded`)?\n\n**Hold behavior**\n3. Does the 10 minutes start at hold creation or when the user reaches checkout? Is it fixed, or can it be extended or reset?\n4. What does a hold reserve? Inventory only, or also a price? If the price changes during the 10 minutes, which one applies?\n5. Can one user have multiple concurrent holds? Is there a cap?\n6. How is expiry enforced: a sweeper job, a TTL in the datastore, or lazy checks at read time? What is the tolerance for inventory staying locked slightly past 10 minutes?\n\n**Confirmation and capture**\n7. What happens if confirmation arrives at minute 9:59 and payment authorization takes 5 seconds? Does the hold expire mid-payment, or is there a grace period or payment-in-progress lock?\n8. If capture fails or is declined, does the hold remain, and for how long?\n9. Is \"capture only at confirmation\" a hard rule (e.g. no pre-authorization at hold time either), or just that funds aren't taken? Is this driven by compliance, cost, or UX?\n10. What are the idempotency expectations for confirmation retries and double-clicks?\n\n**Edge cases and ownership**\n11. If a hold expires but the user's payment succeeds late (e.g. an async provider callback), do you confirm if inventory is still free, or refund?\n12. What do the user-facing UI and API call each state today, and how much external surface would a rename touch?\n\n## Proposed documentation\nKeep it small and close to the code so it stays current.\n\n1. **`docs/glossary.md`**: one entry per term (Hold, Reservation, Booking, Capture, Expiry) with a definition, what it is *not*, and the code and API names it maps to.\n2. **`docs/adr/0001-hold-vs-reservation-terminology.md`**: records the decision to split the term, the alternatives considered, and a migration note for existing \"booking\" usages.\n3. **`docs/adr/0002-hold-duration-and-expiry.md`**: the 10-minute rule, when the clock starts, how expiry is enforced, and the payment-in-flight edge case.\n4. **`docs/adr/0003-capture-only-at-confirmation.md`**: the rule, its rationale, and consequences (e.g. no payment guarantee while a hold is active).\n5. **`docs/reservation-lifecycle.md`**: a state diagram (Mermaid works well in Markdown) with allowed transitions and which actor or event triggers each.\n6. **An \"open questions\" section** in the lifecycle doc for anything the interview leaves unresolved, so gaps are visible rather than implicit.\n\nEach ADR should be short: context, decision, consequences, status, and date.\n\n## Next step\nAnswer whichever questions you can, in any order, and flag the ones you don't know.

It should never be a data-model term.\n\nIf you disagree, the alternative is one entity with a `status` field (`held`, `confirmed`, ...). That is still fine, but the docs must then say that \"booking\" is the entity and \"hold\" and \"confirmed\" are states. Question 1 decides this.\n\n## Interview questions\nEach has my default in case you want to answer \"agree\".\n\n**Model**\n1. Are a hold and a reservation separate entities or one entity with states? *Default: one entity with explicit states, since the confirmed record is the hold converted, and the history stays in one place.*\n2. Is the 10 minutes fixed, or configurable per resource, tenant, or channel? *Default: a single config value, not hardcoded.*\n3. Can a hold be extended, or can a user have multiple holds at once? *Default: no extension, and one active hold per user per resource.*\n\n**Expiry and concurrency**\n4. What happens if confirmation arrives at, or just after, the 10-minute mark? Is there a grace period, and who is the source of truth for time (server clock, DB timestamp)? *Default: server-side `expires_at`, no grace period, and confirmation rejected if expired and the inventory was released.*\n5. If a hold expires but the inventory is still free, can confirmation still succeed? *Default: no, to keep behavior predictable.*\n6. How is expiry enforced: lazy (checked on read), a sweeper job, or TTL in the store? *Default: enforce on read and also run a sweeper, so correctness never depends on the sweeper's timing.*\n7. How do you prevent double-holds on the same inventory under concurrent requests? *(Unique constraint, row lock, or atomic conditional update?)*\n\n**Payment**\n8. Because capture happens only at confirmation, what if capture fails or is declined? Does the hold survive for retry until it expires? *Default: yes, the hold stays and the user can retry until `expires_at`.*\n9. What if capture succeeds but the hold has expired in the meantime? Is that race handled by checking and locking before capture, or by refunding afterward? *This one has real money consequences, so I'd decide it explicitly.*\n10. Is confirmation idempotent? What happens on a double-click or client retry?\n\n**Lifecycle**\n11. What are the full states and allowed transitions? (e.g. `held → confirmed`, `held → expired`, `held → cancelled`, `confirmed → cancelled`.) Is `expired` terminal?\n12. What are the cancellation and refund rules for confirmed reservations? Do they differ from releasing a hold?\n13. Which events should notify the user (hold created, expiring soon, expired, confirmed)?\n\n**Migration**\n14. Existing data and code use \"booking\" for both. Do you need a migration or rename plan, or just a glossary and a deprecation rule for new code?\n\n## Proposed documentation\nKeep it small, and put it in the repo next to the code.\n\n1. **`docs/glossary.md`**: definitions of hold, reservation, and the status of \"booking\" (deprecated, or UI-only). It is the single place to settle terminology.\n2. **`docs/adr/0001-hold-vs-reservation-terminology.md`**: records the naming decision, the alternatives considered, and the migration approach.\n3. **`docs/adr/0002-hold-duration-and-expiry.md`**: the 10-minute duration, who owns the clock, how expiry is enforced, and the late-confirmation behavior.\n4. **`docs/adr/0003-capture-at-confirmation.md`**: why capture happens only at confirmation, plus the failure and race handling from questions 8–10.\n5. **`docs/reservation-lifecycle.md`**: state diagram and transition table with the invariants (e.g. \"no capture while `held`\", \"`expired` is terminal\").\n6. **Code-level anchors**: a constant such as `HOLD_DURATION = 10 minutes` with a comment linking to ADR 0002, and enum names that match the glossary.\n\n### Draft glossary entry\n> **Hold**: A temporary claim on inventory that lasts 10 minutes. No payment is captured. Expires automatically.\n> **Reservation**: A confirmed claim, created when a hold is confirmed and payment is captured.\n> **Booking**: Deprecated as a data-model term. Do not use it in new code, schemas, or API names.\n\n### ADR template\nContext, Decision, Alternatives considered, Consequences, Status, Date.\n\n## Suggested order\nAnswer questions 1, 4, and 9 first. They shape the data model and the money handling, and the ADRs follow from them. The rest can be defaults I draft for your review.",

This is the interview in the grilling style, without the ADR or glossary files.\n\n## Interview\n\n**1. What problem are we solving?**\nYou say checkouts are slow. If a shopper can't finish within 10 minutes, a longer hold helps them. If checkout is slow because of payment or page latency, a longer hold hides the problem. What share of checkouts finish between 10 and 30 minutes, and how many holds expire mid-checkout today? Without those numbers, 30 minutes is a guess.\n\n**2. What does the capacity tradeoff cost?**\nTripling the hold time means each abandoned hold keeps inventory locked three times as long. You haven't accepted that cost, so these need answers first:\n- What is the abandonment rate? Locked-but-unsold inventory scales with it.\n- Which items are scarce enough that a 30-minute lock turns away real buyers?\n- Who owns the decision to trade availability for checkout completion?\n\n**3. Are there cheaper options than a flat 30 minutes?**\n- **Extend on activity:** keep 10 minutes, but renew once when the shopper enters payment.\n- **Tiered holds:** use a longer hold only for in-stock-plentiful items.\n- **Shorter bump:** try 15 minutes and measure before committing to 30.\n\nMy recommendation is to try the activity-based extension first. It targets slow checkouts directly and limits the capacity exposure to shoppers who are actually checking out.\n\n**4. How would we know it worked?**\nDefine the success metric (completed checkouts after hold expiry) and the guardrail (out-of-stock rate and sell-through on constrained items) before any change ships. Also set a rollback condition.\n\n## Status for the proposed note\n\n**Proposed, not accepted.** The note should say:\n- The existing 10-minute expiry remains the standing decision.\n- The 30-minute change is a candidate to help slow checkouts.\n- The capacity tradeoff is unaccepted and has no named decision owner yet.\n- Open items: the data from question 1, the alternatives in question 3, and the metrics in question 4.\n\nThe note should not supersede the 10-minute note until someone explicitly accepts the tradeoff.

Holding inventory three times longer means less available to other buyers.\n\n## Questions I'd press on\n\n1. **What is the actual problem?** Do you know how long slow checkouts take, such as p50, p90 and p99? If p95 finishes in 14 minutes, 30 is overkill, and 15 might fix it.\n2. **Who is slow?** Is it payment failures, 3-D Secure redirects, or form friction? Fixing the cause may beat lengthening the hold.\n3. **What does a hold cost?** What fraction of inventory is held at peak, and what share of holds are abandoned? Tripling the duration roughly triples held-but-unsold stock for abandoners.\n4. **What is scarce?** Capacity is a minor cost for plentiful stock and a major one for limited stock like tickets or last units. Does the answer differ by item type?\n5. **Can it be adaptive?** Options include a 10-minute base hold with a one-time extension when the user reaches payment, or a short hold until the payment step begins and a longer one after. That would give slow payers time without locking inventory for browsers.\n6. **How will you know it worked?** What metrics would you watch, such as checkout completion rate, expired-hold rate, oversell or stockout complaints, and abandoned-hold share? What result would make you revert?\n7. **What breaks downstream?** Do reservation-release jobs, reporting, or customer messaging assume 10 minutes?\n\n## My recommendation\n\nDon't adopt 30 minutes yet. First get the checkout-duration distribution and the held-inventory share. If the data shows a long tail only at payment, prefer an extension triggered at payment over a flat 30. If you still want a flat value, pick the smallest one that covers about p95 to p99.\n\n## Status for the proposed note\n\n**Proposed.** It is not Accepted, because the capacity tradeoff hasn't been agreed.

If most slow ones finish in 12 to 15 minutes, 30 may be more than you need.\n2. **What does a hold consume?** If it's inventory, seats, or slots, a 3x longer hold means roughly 3x more capacity locked at the same abandonment rate. Do you know the abandonment rate?\n3. **What's the capacity tradeoff, concretely?** At peak, how much sellable capacity would sit in expired-soon-but-still-held limbo? Who loses out: other buyers, or revenue from abandoned carts?\n4. **Is there a cheaper alternative?** Options include:\n   - Keep 10 minutes and allow one extension when the user is actively in checkout.\n   - Refresh the hold on payment-step entry.\n   - Use a longer hold only after payment starts.\n5. **Who are the slow checkouts?** If it's a specific segment (a payment method, 3-D Secure, a form-heavy flow), fixing that flow might beat changing the global hold.\n6. **What happens on expiry?** Does a user mid-payment lose the item and still get charged?
