| [Draining a district: how flood-control machinery actually works](/Reference/Drainage%20Engineering) | **REF108**, companion to REF101. Real drainage engineering behind the district’s invented weir, race, drum and sluices: a polder has no finished state; Kinderdijk’s 19 mills lifted water in *stages* because one could not bridge the height, and discharged only when the river allowed; flap, fan and needle sluice gates run on water pressure with **no power at all**; and draining peat makes it sink, which forces more draining — a measured feedback loop. Proposes nothing | [Hold the Flood](/Hold%20The%20Flood) — [World and Mystery](/Hold%20The%20Flood/World%20And%20Mystery)’s machinery and [D019](/Hold%20The%20Flood/Brief)’s many districts |
| [Survivorlike Market Data](/Reference/Survivorlike%20Market%20Data) | What this would ship beside, measured from Steam's own endpoints on a stated date: which tag actually carries the genre's traffic, **§2** the list prices of the eleven titles sampled, review counts, engaged-player playtime medians, and the exact refund policy. **§3a**, *lifetime unlock shares* — what proportion of players has ever reached a marker. **§3b**, *ratios between ordered markers, and what they do not mean.* **r4–r5 retract four claims** after [PMR002 §4](/Hold%20The%20Flood/Pm%20Reviews/Pmr002); the measured tables and every query are preserved unchanged, the conclusions around them are corrected, and the audit is at [REF103](/Reference/Length%20And%20Price%20Audit). Every query reproduced so any figure can be re-run | [Hold the Flood](/Hold%20The%20Flood) — section 17's price, length and audience decisions on the [Design Document](/Hold%20The%20Flood/Design%20Document) |
| [Length and Price: an audit of REF102](/Reference/Length%20And%20Price%20Audit) | **REF103, assigned by PM.** Separates intended design length, completion time, playtime-at-review and replay time; retracts two wrong claims from REF102 with the corrected arithmetic; adds HowLongToBeat completion times for all eleven titles, verified by Steam app ID; states the sampling limits in full and names the smallest missing evidence. **§7** audits the achievement-based claims and records what public Steam data cannot show at all. **r3** applies PMR003's closing qualifications to this page's own §§2, 3, 6 and 7.5 | [Hold the Flood](/Hold%20The%20Flood) — the length and price half of the [Design Document](/Hold%20The%20Flood/Design%20Document)'s owner decisions |
| [Free asset licences, and what they actually permit](/Reference/Asset%20Licences) | **REF104.** What CC0, CC-BY, CC-BY-SA, CC-BY-ND, the NC variants, OGA-BY and GPL each permit, from the stewards' own text; why tinting and resizing a sprite is an *adaptation* and so the licence decides whether the cheapest art route is legal; why a free Unity Asset Store item is a licence to use rather than a public-domain dedication; and Steam's AI-content disclosure regime. Confirms the lead's two asset checks independently. **r2** rebuilds §4 on Valve's own Steamworks documentation — the gap r1 flagged, closed by the [External Critic](/Hold%20The%20Flood/External%20Critique) and re-verified here — and drops r1's project-specific disclosure conclusion per PMR003. Reference work only: not legal advice, not asset approval, not a submission decision | [Hold the Flood](/Hold%20The%20Flood) — [Design Document](/Hold%20The%20Flood/Design%20Document) §14's asset lever and the [Brief](/Hold%20The%20Flood/Brief)'s requirement to record each asset's actual terms |
