# Packetloss404 Mountain Side Estate — vertical buildout package

Date: 2026-08-27 UTC  
Planning run: `RUN-20260827-MOUNTAIN-SIDE-ESTATE-VERTICAL-BUILDOUT`  
Live build run: `RUN-20260827-ESTATE-BUILDOUT`  
State: **built in the live world; exact saved-world and restart verification passed**

This package turns the measured unfinished Estate shells into a complete private
home, real theater, operational lift, independent monumental stair, and broad
Y3 Grand Hall. It does not create a hotel, rental complex, club, public station,
or political-propaganda space. Hotel Grand Central remains the separate site at
the east-gap build.

The ten exact patches were generated from the frozen saved-world baseline. The
complete forward/restart/functional/reverse chain first passed on an isolated
Paper clone, then all ten operations were applied serially as the first part of
the 14-operation Estate live chain. The saved live world passed exact composed
verification both before and after a real Paper service restart.

## Evidence and confidence

| Field | Value |
|---|---|
| Primary saved-world source | `/opt/minecraft/minecraftv5.0/region`, captured in `fixtures/mountain-side-estate-floor-survey-20260827.json` |
| Observation run / time | `RUN-20260827-ESTATE-FLOOR-SURVEY`; `2026-08-27T01:46:26+00:00` |
| Planning constraints | `plans/mountain-side-estate-integration-acceptance-20260827.json`, revision generated `2026-08-27T00:00:00Z` |
| Method | Exact saved-Anvil block-state and block-entity scan after a zero-player `save-all flush`; full-footprint material counts; two-block-clear walkable-floor BFS; finite six-neighbor fluid-component tracing; exact predecessor/after-state composition |
| Geometry confidence | High for the frozen bounds, existing blocks, entities, fluids and protected controls at the measured save boundary |
| Design confidence | High for coordinate fit, Paper state normalization, static safety and the asserted traversal routes; verified by the passing isolated-clone forward/restart/functional/reverse proof |
| Authorization | Owner explicitly authorized implementation on 2026-08-27; clone proof, serialized live apply, fresh saved-world controls, and restart persistence all passed |

The generated operation index records the baseline region hash used by every
patch. Exact live operation journals and recovery records remain the rollback
authority; the package must never be replayed against a different predecessor.

## Live as-built proof

`fixtures/mountain-side-estate-live-verification-20260827.json` records the
complete 14-operation live proof. At `2026-08-27T03:19:35+00:00` it verified
**151,285 input records**, **146,912 composed final coordinates**, and **4,373
intentional successor overrides** with zero mismatches. Paper was restarted at
the service level and the complete exact and functional suite passed again.

The live proof covers this ten-operation vertical package plus the four deeper
mini-estates. It confirms the 195-cell Grand Stair, the retained 244-cell legacy
stair, all ten lift landings, the Hall-to-lift link, the theater route, twelve
private-deck routes, all four Hall gates, all four houses and false skies, zero
residual fluid in the three contained pockets, and unchanged protected controls.

## Isolated-clone proof

`fixtures/mountain-side-estate-vertical-buildout-clone-roundtrip-20260827.json`
records a passing rehearsal from `2026-08-27T03:07:27Z` through
`2026-08-27T03:08:37Z` against `r.0.0.mca` SHA-256
`145056b32e9a05dfb19d481d1df5d2a5d3c47b942d4d4a5ef300b40349b3872f`.
The clone report SHA-256 is
`0b89c3000eb1020574aea005420b0c3ef4081fa11cd713265a035db5a3624cb2`.
It proves:

- all ten forward operations and 101,265 exact records verified;
- 96,892 composed final coordinates remained exact across a Paper restart;
- all ten lift/stair stops, both stair routes, twelve private-room routes,
  stage egress, four Hall gate connectors and the Hall-to-lift passage passed;
- all three bounded fluid components had zero residual lava/water;
- protected controls were identical before and after; and
- all ten operations reversed to the exact saved-world predecessor state.

## Frozen geometry and program

| Element | Exact owned geometry | Program / treatment |
|---|---|---|
| Estate property shell | `[186,3,64]..[368,93,282]` | Private homebase; all work remains inside it. |
| THR / Spine easement | `[369,2,192]..[383,15,287]` | **No touch.** x368 is also retained as a one-block buffer. |
| Twin bubble lift | `[346,3,182]..[354,90,190]` | Separate glass UP and DOWN columns; stops Y3, Y24, Y38, Y45, Y50, Y55, Y60, Y65, Y70 and Y81. |
| Grand-stair atrium | `[355,3,194]..[367,84,212]` | Four-block-wide switchback flights, broad landings, two-block headroom and a Y84 roof over the Y81 stop. |
| Grand-stair cap extension | `[355,82,194]..[367,84,212]` | Exact scan: 741 blocks = 685 stone, 38 air and 18 coal ore; no fluid, player hint or block entity. |
| Theater stack | `[283,55,162]..[328,74,225]` | Y70 grand lobby; Y65 lounges/balcony; Y55 auditorium datum. |
| Full-height bowl | `[285,55,164]..[315,70,208]` | Stage/screen, backstage wings, eight raked seating rows, center/side aisles, rear balcony and projection booth. |
| Approved Y60 removal | `[285,60,164]..[315,60,208]` | Exactly 1,395 stone; no player hint or block entity. |
| Approved Y65 opening | `[285,65,164]..[306,65,208]` | Exactly 990 stone; the rear Y65 balcony remains. |
| Private deck stack | `[283,38,162]..[328,54,249]` | Y50 suites; Y45 library/map/offices/workshop; Y38 storage/utilities/service/rail buffer. z250..258 stays outside the fitout to retain the old stair approach. |
| Broad Grand Hall | `[240,3,132]..[337,24,188]` | Monumental private-estate hall, dry gardens, display, symbolic armory, processional circulation and four illuminated estate gates. |
| Y3 transition buffer | `[240,3,189]..[337,24,194]` | No blanket work; only the enumerated cross-gap connectors may enter it. Existing southeast terraces remain intact. |

The bubble lift is not decorative. Its UP column is `x348,z184,Y4..89`
over soul sand and its DOWN column is `x352,z184,Y4..89` over magma. Each
stop has a dry landing, distinct green/blue floor band and two-block sign-held
water aperture. The stair is wholly separate from the lift.

The original winding stair also remains an independent egress. A 244-cell
saved-world route from player-foot cell `(299,5,274)` to `(316,71,184)` is
point-protected through its support, feet and head cells. The composed virtual
plan still passes that route with two-block body space.

## Fluid containment gate

The first review found water/lava intersecting intended landing headroom. The
final chain does not skip or work around those sources. It measures and contains
their complete terminating 6-neighbor components:

| Pocket | Exact component | Blocks |
|---|---|---:|
| Lower link lava | `[359,27,183]..[364,27,193]` | 43 lava |
| Y50 lava | `[342,50,196]..[350,52,203]` | 76 lava |
| Y55 water | `[337,53,194]..[348,56,205]` | 75 water |

The first operation builds dry deepslate containment shells without changing a
fluid. The second changes exactly all 194 sealed fluid coordinates to solid
deepslate. Only then may corridor containment and excavation proceed. Every
fluid record retains its exact before state for reverse restoration. The final
generator records zero skipped fluid assignments.

## Grand Hall structure and heritage

The old bedrock divider cross is not left as four solid room walls. Ten narrow,
fail-closed arches remove exactly 992 bedrock blocks after an independent
predecessor has installed quartz frames and successor lighting:

| Divider | Arch boxes and exact bedrock count |
|---|---|
| x264 | `y5..13,z138..148` (99); `y5..13,z159..169` (98 + one existing air); `y5..13,z176..186` (99) |
| x273 | the same three z bands, 99 each |
| z154 | `x245..257,y5..13` (117); `x265..272,y5..8` (30 + two existing air); `x280..292,y5..13` (117); `x307..321,y5..13` (135) |

All other bedrock remains a structural pier, colonnade or lintel. No arch point
contains fluid or a block entity. The hanging sign at `(271,5,155)` — “Dave was
here / 12-23-24” — remains exactly in situ.

A separate, owner-approved Hall-to-lift opening changes exactly ten additional
bedrock blocks at `[339,5,183]..[339,6,187]`, scope
`grand-hall-lift-link-bedrock-opening`. Operation 9 installs its quartz frame
and lighting first; operation 10 opens it with exact recovery states. This is
not part of the 992 Hall-arch count, and every other block in the continuous
x339 divider remains untouched.

Successor ceiling and floor lighting contains 113 sea-lantern points. Only the
following operation retires the 103 old wall torches. Four lit private-estate
gates terminate adjacent to the other workstream's exact handoffs:

- R4: `(238,3,130)`
- R3: `(303,3,130)`
- R2: `(238,3,190)`
- R1: `(277,3,190)`

No Hall record enters a mini-estate envelope. The south transition connectors
are individually enumerated in the virtual-QA fixture; there is no bounding-box
clearance in z189..194.

## Exact operation chain

The sequence is mandatory because later patches consume exact predecessor
states. Every operation is below the 64-chunk runner cap.

| # | Operation | Exact records | Chunks | Changed bounds |
|---:|---|---:|---:|---|
| 1 | `build-mountain-side-estate-fluid-containment-shells-20260827` | 1,086 | 3 | `[336,26,182]..[365,57,206]` |
| 2 | `build-mountain-side-estate-fluid-neutralization-20260827` | 194 | 3 | `[337,27,183]..[364,56,205]` |
| 3 | `build-mountain-side-estate-vertical-containment-20260827` | 14,445 | 7 | `[329,3,182]..[367,90,212]` |

| 7 | `build-mountain-side-estate-theater-fitout-20260827` | 12,249 | 20 | `[283,55,162]..[328,74,225]` |
| 8 | `build-mountain-side-estate-private-decks-20260827` | 31,185 | 24 | `[283,38,162]..[328,54,249]` |
| 9 | `build-mountain-side-estate-y3-grand-hall-lighting-20260827` | 6,020 | 28 | `[240,3,132]..[343,22,188]` |
| 10 | `build-mountain-side-estate-y3-grand-hall-finish-20260827` | 8,003 | 30 | `[239,3,130]..[339,22,190]` |

Total: **101,265 exact records** and **96,892 unique final coordinates**.

## Palette and rough material order

The palette is derived from the Estate's surviving quartz, stone brick, glass,
oak, terracotta, glowstone and gold vocabulary. The net final additions, rounded
up for procurement, are:

| Material family | Net placed blocks | Suggested order |
|---|---:|---:|
| Smooth stone | 12,000 | 12,250 |
| Deepslate tiles | 11,594 | 12,000 |
| Smooth quartz | 10,394 | 10,750 |
| Polished deepslate | 7,554 | 7,800 |
| Polished andesite | 7,219 | 7,500 |
| Dark-oak planks | 5,726 | 6,000 |
| Light-gray concrete | 2,670 | 2,800 |
| Quartz pillars | 2,251 | 2,400 |
| Polished-blackstone bricks | 2,097 | 2,250 |
| Light-gray terracotta | 2,047 | 2,200 |
| Deepslate bricks | 1,447 | 1,600 |
| Polished blackstone | 1,351 | 1,500 |
| Iron bars | 1,070 | 1,200 |
| Glass / tinted glass | 690 | 800 |
| Stone bricks | 639 | 700 |
| Bookshelves | 413 | 450 |
| Sea lanterns | 318 | 350 |
| Black / white / red concrete | 824 | 900 |
| Copper blocks, iron blocks and gold accents | 317 | 375 |
| Bubble columns | 172 | direct exact states; not an inventory order |

No new chest, barrel, furnace inventory, armor stand, item frame, minecart or
other entity is part of this package. The armory is architectural display only.

## Protected controls and conflicts

Every manifest rechecks these independent controls before and after mutation:

- exactly 14,724 glowstone blocks in `[260,32,130]..[344,36,262]`;
- 206 powered rails and nine ordinary rails in the separate THR easement;
- the six upper theater-entry signs in `x315..316,y71..73,z182..185`;
- the two dungeon chests and one spawner at `x309..318,y64..70,z132..141`;
- the Hall heritage sign and all four Room signs.

The generator also rejects or skips every legacy block entity, player-fabric
coordinate, entire legacy-stair envelope, retained-egress support/body cell,
roof-control coordinate, existing fluid not in the exact neutralization set,
and any rail/buffer coordinate. The two static package reviews pass with zero
errors and zero warnings.

## Recovery and completed live sequence

The completed live operation followed this gate sequence:

1. Re-run the generator against a fresh zero-player, `save-all flush` boundary.
2. Confirm every manifest/patch hash and every control count is unchanged.
3. Copy the affected region to an isolated Paper clone.
4. Run all ten manifests in order. Verify exact after states, normalized new
   sign entities, lift column persistence after restart, all ten landings, the
   195-support grand-stair path, the 244-cell retained-stair path, room-to-core
   routes, two-block headroom, fluid absence and all protected controls.
5. Restore the ten operations in reverse order and require exact initial-state,
   entity and control restoration.
6. Acquire the root-serialized global mutation lock, recheck zero players and
   flush immediately before operation 1; apply the exact chain and repeat the
   saved-world checks across a real Paper restart.

The runner creates a checksum-verified region backup in each operation journal
before applying. On any precondition, control, exact-after, route or save check
failure, stop the chain and use `tools/mcpatch.py restore --apply --yes RUN_ID`
for the failed run, then restore already-completed predecessors in reverse order.
Do not attempt a partial forward repair while the chain is inconsistent.
