the source material behind every answer.

Corpus coverage

Source of truth for what Meridian Nine Coworking's policy docs do and do not answer. Used to write `evals/cases.json` and to sanity-check any refusal a reviewer sees in the demo — a refusal is only "correct" if the topic is actually listed as a gap below.

Files

Topics covered (answerable)

Pricing and tiers, membership limits, booking/cancellation mechanics, refund rules, building hours and access, keycards, holiday closures, guest policy, damage/liability for both personal and company property, premises insurance (for the building, not for members — see gaps), equipment and loaner gear, printing costs, wifi.

Topics deliberately never covered (gaps)

These are never mentioned anywhere in the corpus. A correct system refuses on all of them. Every eval case in the `unanswerable` bucket that isn't a near-miss targets one of these.

1. Insurance coverage for members' own property or business — the corpus states

Meridian Nine's *premises* liability insurance and requires outside event bookers to carry *their own* certificate of insurance, but never says whether a member's equipment, inventory, or business activity is covered by anything. See the insurance near-miss below.

1. Corporate invoicing / NET-30 / purchase orders — billing is described only as

recurring card charges. Invoicing terms for corporate procurement are never mentioned. See the Team Accounts near-miss below.

1. Accessibility specifics (ADA compliance, accessible restrooms, desk heights) —

the corpus mentions a step-free entrance in passing but never states ADA compliance, accessible restroom availability, or accessible desk/workstation specifics. See the accessibility near-miss below.

1. Pet policy — never mentioned in any document. No near-miss; a query about pets

should retrieve weakly across everything and refuse cleanly.

1. Parking — never mentioned. See the parking near-miss below.
2. Data privacy / handling of personal information — wifi signup and billing are

described mechanically, but nothing states what happens to the personal data collected (retention, sharing, deletion rights, etc). No near-miss; should retrieve weakly.

Near-miss passages

Content that is topically adjacent to a gap, will retrieve with high similarity, and will tempt a naive RAG system into fabricating an answer that isn't actually supported.

What "correct" looks like

- A question inside "Topics covered" → `answered`, with citations resolving to real passage IDs from the relevant file(s). - A question about any of the 6 gap topics above, including one that fishes near a near-miss passage, → `refused`, with `citations: []` and a grounding score below threshold (near-miss retrieval will often *pass screening and retrieval* with a plausible-looking passage at high similarity — the point is that generation or grounding catches it, not that retrieval refuses to return anything).

Booking & Cancellation

How to book a meeting room

Meeting rooms are booked through the member portal or the Meridian Nine mobile app. Rooms can be booked up to 30 days in advance and in 30-minute increments, with a 30- minute minimum booking length. There are three room sizes: Huddle (seats 2-4, standard rate $12/hour), Conference (seats 6-10, standard rate $22/hour), and Boardroom (seats up to 16, standard rate $38/hour, includes video conferencing equipment). Tier-included credit (see Pricing) is applied automatically to any room type before the standard rate is charged for remaining time.

Cancelling a booking

A booking can be cancelled free of charge up to 4 hours before its start time. Credit or payment used for that booking is fully restored. Cancellations made less than 4 hours before the start time forfeit the credit or payment for that booking — there is no partial refund for a late cancellation.

No-shows

A booking with no check-in within 15 minutes of its start time is automatically released and marked as a no-show. No-shows forfeit the credit or payment used, same as a late cancellation. A member with 3 no-shows in a rolling 30-day period loses the ability to book more than 24 hours in advance for the following 30 days.

Recurring bookings

Members can set up a recurring weekly booking for the same room and time slot, subject to availability. A recurring series can be cancelled as a whole or edited one occurrence at a time from the portal. Each occurrence in a recurring series follows the same 4-hour cancellation window as a one-off booking.

Same-day and walk-up bookings

Rooms with no reservation on the calendar can be booked same-day, including on a walk-up basis by checking room availability on the lobby display screen. Walk-up bookings still deduct from the member's credit balance or charge the standard rate the same as an advance booking.

Day Pass booking restrictions

As noted in Pricing, Day Pass holders cannot reserve a room more than 2 hours in advance and cannot use tier credit (they have none) — Day Pass room use is always billed at the standard hourly rate shown above.

Building-wide closures

If Meridian Nine closes a room or the building for maintenance or a scheduled closure (see Hours & Access for holiday closures), any existing bookings in the affected window are cancelled automatically and any credit or payment used is fully restored — this is not treated as a member cancellation and does not count toward the no-show limit.

Damage & Liability

Member responsibility for personal property

Members are responsible for their own personal belongings, laptops, and business equipment at all times. Meridian Nine does not accept responsibility for personal property that is lost, stolen, or damaged while on the premises, whether left at an assigned desk, in an office, or in a shared area.

Damage to Meridian Nine property

A member who damages Meridian Nine furniture, equipment, walls, or fixtures — whether by accident or otherwise — is responsible for the cost of repair or replacement at fair market value. Damage should be reported to the front desk as soon as it happens; damage discovered later that can reasonably be traced to a specific member's use (for example, a booked room found damaged immediately after that booking) will be billed to that member's account.

Found property

Items found in shared areas are held at the front desk for 30 days and logged in the lost-and-found register. Unclaimed items are donated or discarded after 30 days. Meridian Nine is not liable for the condition of found items while they are being held.

Premises insurance

Meridian Nine Coworking LLC carries commercial general liability insurance covering the physical premises and common areas, consistent with standard commercial landlord practice. As noted in the Guest Policy, outside organizations booking event space must separately provide their own certificate of insurance naming Meridian Nine as additionally insured for the duration of their event.

Injury on premises

A member or guest who is injured on the premises should report the incident to the front desk immediately so an incident report can be filed. Members and guests use common areas, meeting rooms, and all facilities at their own risk; Meridian Nine's premises insurance covers the building and common areas as noted above, but members and guests are expected to exercise reasonable care in their own use of the space.

Community conduct and space damage from misuse

Repeated damage or a pattern of misuse of shared equipment or furniture may result in a conversation with Meridian Nine staff and, in serious or repeated cases, suspension of membership in addition to any repair costs billed to the member's account.

Equipment

Printing

The shared printer/scanner is available on every floor. Black-and-white pages are free up to each tier's monthly allowance (see Membership Limits) and $0.10 per page beyond that allowance. Color pages are $0.35 per page regardless of tier and are never included in the free allowance. Print jobs are released by tapping a member's keycard at the printer.

Meeting room AV equipment

Conference and Boardroom rooms include a wall-mounted display with HDMI and USB-C input, a conferencing speakerphone, and built-in video conferencing camera and microphone compatible with common video call platforms. Huddle rooms include a smaller wall-mounted display with HDMI/USB-C input but no dedicated conferencing camera. Members should report any AV issue to the front desk during staffed hours; there is no after-hours AV support.

Loaner equipment

The front desk keeps a small pool of loaner equipment available on a first-come, first-served basis at no charge: HDMI and USB-C adapters, phone chargers (USB-C, Lightning, and micro-USB), and a limited number of loaner laptop chargers for common brands. Loaner items must be returned to the front desk the same day they are borrowed.

Standing desks and desk accessories

Every desk in the open lounge and in shared pods is a sit-stand adjustable desk. Dedicated Desk and Private Office members may request a monitor arm, footrest, or desk lamp from the front desk at no additional charge, subject to availability. External monitors are not provided by Meridian Nine and are not available as loaner equipment — members who want a second monitor at their desk should bring their own.

Kitchen equipment

Each floor's community kitchen includes a drip coffee machine, an espresso machine (Dedicated Desk and Private Office floors only), a filtered water tap, a microwave, and a refrigerator with labeled shelf space available to any member on a first-come basis. Members should label perishable items with their name and date; unlabeled items are discarded weekly during kitchen cleaning.

Equipment for outside events

Outside organizations booking the Boardroom for an event (see Guest Policy) may request additional AV equipment such as a projector or extra microphones through the front desk at an additional rate quoted at booking time; availability is not guaranteed and should be confirmed at least 5 business days before the event.

Guest Policy

Bringing a guest

All guests must be signed in by their host member at the front desk during standard building hours and must wear a visitor badge for the duration of their visit. A guest cannot enter using a member's keycard and cannot be signed in remotely — the host member must be on-site to sign a guest in.

Guest visit allowances

Flex members may bring up to 4 guest visits per month at no charge. Dedicated Desk members get 8 guest visits per month at no charge. Private Office members have unlimited guest visits. A "visit" is counted per guest per day regardless of how long they stay. Guest visits beyond a tier's monthly allowance are billed at $10 per guest per visit.

What guests can access

A signed-in guest may sit with their host member in the open lounge and use guest wifi (a separate network from member wifi, issued at the front desk per visit). Guests cannot independently book meeting rooms, use the printer, or access any keycard-restricted area; a guest using a meeting room must be accompanied by their host member, and the booking is made under the host's account and draws from the host's credit.

Guests at private events

A member hosting a larger gathering (more than 6 guests at once) in a booked meeting room should notify the front desk in advance so extra badges can be prepared. Groups above 15 people are treated as an outside event booking rather than a standard guest visit — see the note on outside event bookings below.

Outside event bookings

Meridian Nine's Boardroom and Conference rooms can be booked by outside organizations for private events outside of a member's guest allowance, subject to availability and a separate event rate quoted by the front desk. Any outside group booking an event space must provide a certificate of insurance naming Meridian Nine Coworking LLC as additionally insured before the event date, regardless of event size.

Guest conduct

Guests are expected to follow the same community guidelines as members, including quiet hours in focus areas and normal building courtesy. A host member is responsible for their guest's conduct while on premises.

Hours & Access

Standard building hours

Meridian Nine's standard hours are Monday through Friday, 7:00 AM to 9:00 PM, and Saturday 9:00 AM to 5:00 PM. The building is closed to members on Sundays except for Private Office members, who have 24/7 access every day of the week regardless of the standard schedule.

24/7 access

Dedicated Desk and Private Office members get 24/7 keycard access every day, including Sundays and holidays. Flex and Day Pass members are limited to standard building hours listed above and cannot enter outside those windows even with a valid keycard.

Keycard access

Every membership above Day Pass includes a personal keycard, issued at the front desk on the member's first visit after signup. A lost keycard should be reported immediately through the member portal so it can be deactivated; a replacement keycard costs $15. Keycards are personal and should not be shared — access is logged per card, and repeated shared use may result in the card being deactivated pending a conversation with the member.

Holiday closures

Meridian Nine is closed to Flex, Dedicated Desk (for staffed services, though keycard access remains available), and Day Pass members on New Year's Day, Independence Day, Thanksgiving Day, and Christmas Day. Front desk staff and community programming are not available on these days even though the building itself remains accessible to badge-holding members. The front desk posts the full holiday schedule for the coming year each December.

Building entrance and location

Meridian Nine's main entrance is on Fifth Street, one block from the Fernbridge Transit Center, which serves the Blue and Green light rail lines and several bus routes. The Fifth Street entrance has street-level access with no stairs from the sidewalk to the lobby. A secondary entrance off the rear alley is available for deliveries and is not a member entry point during standard hours.

Wifi and technology

All members receive a private, password-protected wifi network with a unique login issued at signup, separate from the guest wifi network described in the Guest Policy. Wifi speeds are not tiered by membership level — every member gets the same connection.

Front desk staffing

The front desk is staffed during standard building hours listed above. Outside those hours, the space operates unstaffed for members with 24/7 access; there is no on-site staff to assist with issues overnight or on Sundays, though the after-hours support line posted at the front desk can be called for building emergencies.

Membership Limits

Occupancy and desk limits

Each Flex or Dedicated Desk membership covers one named individual. A membership is not transferable between people day to day — the person using the space should be the member on file, not a coworker or friend using their card. Members who want a colleague to have regular access should get that colleague their own membership or add them as a guest under the Guest Policy.

Meeting room credit limits

Meeting room credit does not roll over between months. Unused hours expire at the end of each billing cycle. Flex members get 8 hours/month, Dedicated Desk members get 16 hours/month, and Private Office members have unlimited credit. Credit is deducted in 30-minute increments, rounded up.

Printing limits

Every membership tier except Day Pass includes 100 free black-and-white pages per month. Pages beyond that allowance, and all color pages, are billed per the rates in the Equipment policy. Unused page allowance does not roll over.

Storage limits

Dedicated Desk members get one lockable under-desk drawer, roughly 12 inches deep. Private Office members can store items freely within their office. Flex and Day Pass members have no on-site storage and should not leave personal items in the open lounge overnight — Meridian Nine is not responsible for items left in open, shared areas (see Damage & Liability).

Simultaneous bookings

A single membership can hold at most 2 confirmed meeting room bookings at any given time. A third booking cannot be placed until one of the first two either occurs or is cancelled. This limit exists per member, not per Team Account — each teammate on a pooled Team Account can independently hold 2 bookings even though they share one credit balance.

Guest limits

See the Guest Policy document for the number of guest visits included per tier per month.

Pricing & Membership Tiers

Meridian Nine Coworking offers four membership tiers. All prices are in USD and billed in advance. There is no long-term contract on any tier — every plan is cancel-anytime unless otherwise noted.

Day Pass

A Day Pass costs $28 and grants access to the open work lounge on the 2nd floor from 8:00 AM to 8:00 PM on the day of purchase. Day Pass holders get one drip coffee or tea from the community kitchen, standard wifi, and access to the shared printer at the per-page rate described in the Equipment policy. Day Pass holders cannot book meeting rooms in advance — meeting rooms are available to Day Pass holders only on a walk-up, space-available basis.

Flex Membership

Flex Membership costs $189 per month. It includes unlimited access to the open work lounge on the 2nd and 3rd floors during standard building hours, 8 hours of meeting room credit per month (see Booking & Cancellation for how credits work), unlimited coffee and tea, and priority printer queue. Flex members do not get an assigned desk — seating is first-come, first-served among Flex and Day Pass members.

Flex Membership is billed monthly on the date of signup. A member who signs up on the 14th of the month is billed on the 14th of every subsequent month.

Dedicated Desk

Dedicated Desk costs $429 per month. It includes everything in Flex Membership plus a permanently assigned desk in a shared pod (4-6 desks per pod), a lockable under-desk storage drawer, 16 hours of meeting room credit per month, and 24/7 building access via keycard (see Hours & Access for details on after-hours entry). Dedicated Desk members may leave a second monitor, keyboard, and personal items at their desk between visits.

Private Office

Private Office pricing starts at $1,150 per month for a 1-2 person office and scales up by office size; the largest standard private office (accommodates up to 6 people) is $3,400 per month. Exact pricing for a specific office depends on square footage and is quoted at tour time. Private Office includes everything in Dedicated Desk, unlimited meeting room credit, a lockable door, and the member's business name listed on the building directory in the lobby.

Private Office is the only tier available on an annual contract with a 10% discount; month-to-month Private Office is also available at the standard rate.

What is not included in any tier

No membership tier includes printing beyond the free monthly page allowance described in the Equipment policy — additional pages are billed per-page. Meeting room credit beyond a tier's monthly allowance is billed at the standard hourly rate described in Booking & Cancellation.

Team Accounts

Two or more Flex or Dedicated Desk memberships under the same company name can be linked into a Team Account at signup or at any later renewal date. Linking memberships into a Team Account pools each member's meeting room credit into a single shared balance for the team, and lets any teammate book a room against that pooled balance. Team Accounts do not change the per-seat price — each seat is still billed individually at its tier's monthly rate, and the team's card on file is charged once per seat per billing cycle.

Switching or cancelling a tier

Members can upgrade tiers at any time; the new rate applies starting the next billing cycle. Downgrading follows the same rule — a downgrade submitted mid-cycle takes effect at the next renewal, not immediately, and the member keeps their current tier's access for the remainder of the paid cycle. To cancel entirely, a member gives notice through the member portal at least 5 business days before their next billing date; membership access continues through the end of the already-paid cycle.

Refunds

Membership refunds

Monthly memberships (Day Pass, Flex, Dedicated Desk) are not refundable once a billing cycle has started. A member who cancels mid-cycle keeps access through the end of the cycle they already paid for, per the cancellation terms in Pricing, but does not receive a prorated refund for the unused portion of that cycle.

Annual Private Office refunds

Annual Private Office contracts (see Pricing) may be cancelled early with 60 days' written notice. Cancelling an annual contract early forfeits the 10% annual discount retroactively — the member is charged the difference between the discounted annual rate already paid and the standard month-to-month rate for the months already used, then refunded any remaining balance from the original annual payment.

Day Pass refunds

A Day Pass is refundable in full if cancelled at least 2 hours before the visit date via the member portal. A Day Pass is non-refundable once that window has passed or once the member has checked in at the front desk.

Meeting room credit and payment refunds

Refunds for meeting room bookings follow the cancellation terms in Booking & Cancellation: a booking cancelled at least 4 hours ahead is refunded in full (credit restored or payment reversed); a late cancellation or no-show is not refunded.

How refunds are issued

Any approved refund is issued to the original payment method on file. Card refunds typically post within 5-10 business days depending on the card issuer. Meridian Nine does not issue cash or check refunds under any circumstance.

Billing disputes

A member who believes they were charged in error has 30 days from the charge date to raise a dispute through the member portal's billing section or by emailing billing@meridiannine.example. Disputes raised after 30 days are reviewed at Meridian Nine's discretion and are not guaranteed a refund.
