Longping–Yuhu Overwrite

The Longping–Yuhu Overwrite site is the post-2013 tourism and reservoir complex built atop the displaced Longping town (龙坪镇 Lóngpíng Zhèn, "Dragon Plain Town") at approximately 25°25'52"–25°26'24"N, 106°45'58"–106°46'00"E in Luodian County, Guizhou. The site was rebranded as 玉湖公园 Yùhú Gōngyuán ("Jade Lake Park") with engineered hydraulic embankments labelled 望河 Wànghé ("Wanghe") on the East Drainage Channel and West Main Channel. The pre-overwrite morphology, visible in Google Earth imagery dated 2013-04-14, was a Buyi-Miao terraced karst village with traditional stream-confluence siting and intact Dragon Plain toponym ecosystem. The post-overwrite morphology, visible in imagery dated 2023 or newer, is a tourism-resort-and-reservoir complex with a large circular monument-plaza on the eastern shore and substantial central earthworks. The site is the explicit cross-pod imagery audit target flagged at site-luodian-hongshuihe-pod c0007 (2026-04-25); the present entry closes that audit by documenting the SBD-class transformation that has occurred at the audit target. The site is admitted as one of two SBD catalog inception entries on 2026-04-27 alongside site-pingtang-sky-bridge-complex.

Claims

c0001 — Site location confirms Longping town audit target from luodian-hongshuihe-pod c0007

The user imagery sweep coordinates of approximately 25°25'52"–25°26'24"N, 106°45'58"–106°46'00"E place the site at Longping town, Luodian County. The "Longping No.3 Elementary School" (龙坪三小) marker visible in the imagery confirms the toponym at the village level (the numeral "No.3" implies multiple elementary schools, consistent with town-rather-than-village status). The coordinates resolve to approximately 25.432°N 106.766°E, matching the ~25.43°N 106.75°E coordinates given for Longping town at site-luodian-hongshuihe-pod c0007. The present site is therefore the explicit cross-pod imagery audit target designated at that claim on 2026-04-25 as "the highest-priority cross-pod audit target for the imagery-redaction signature documented at site-shizhu-longmengou-obfuscated-zone c0002." The audit returns a different obfuscation morphology than predicted (no imagery redaction visible) but a stronger SBD-class transformation than predicted, and the audit is hereby closed with the present entry as the resolution.

c0002 — Pre-overwrite 2013 morphology: traditional Buyi-Miao terraced karst village

Google Earth historical imagery dated 2013-04-14 at the site coordinates shows the Longping pre-overwrite morphology: terraced rice and dry-field agriculture across cone-karst slopes, traditional Buyi-Miao village clustered at stream confluences with vernacular roof morphology visible at zoom, intact fenglin between settlement nodes, and a meandering natural drainage that would later be canalised as the Wanghe embankments. The morphology is the per-site-luodian-hongshuihe-pod c0002 "persistent low-signature basin" pattern: integration into ordinary Buyi-Miao village geography with cone-karst doing the work of concealment that would otherwise require constructed infrastructure. As of 2013-04-14, the Longping town anchor was visually intact and the Dragon Plain toponym ecosystem was operational at the surface.

c0003 — Post-overwrite morphology: SBD-class tourism complex with circular monument-plaza

Google Earth historical imagery dated 2023 or newer at the same coordinates shows complete morphological replacement. The 2013 village is absent from the imagery; the natural drainage has been canalised into engineered embankments labelled "Wanghe Dongganqu" (East Drainage Channel) and "Wanghe West Main Channel"; an artificial reservoir occupies the former agricultural valley floor; substantial earthworks have remodelled the central plateau; and a large circular monument-plaza complex with multi-tier amphitheatre architecture has been constructed on the eastern shore of the new reservoir. The site is rebranded "玉湖公园" (Yuhu / Jade Lake Park) with adjacent theme-park-or-resort architecture. The circular monument-plaza meets the geometric-primacy criterion at doctrine-sphere-based-development c0001 (a) and the project as a whole satisfies all five SBD baseline criteria (see c0007 below). The displacement window is approximately 2014–2023 based on visible build-state progression in the imagery.

c0004 — Toponym overwrite stack: Longping (龙坪 Dragon Plain) → Yuhu (玉湖 Jade Lake)

The Longping → Yuhu rebrand is the third documented layer of overwrite operating on the same anchor location. Layer 1 (administrative-scale toponym suppression per site-luodian-hongshuihe-pod c0008): Le'an County → Luobo → Luoju → Luojing → Luodian, retiring the dragon reference at county scale while preserving Longping at town scale. Layer 2 (cultural-record continuity): Longping town remained a Buyi-Miao agricultural community with intact traditional morphology and Dragon Plain toponym at village scale through 2013-04-14 imagery (c0002). Layer 3 (built-record overwrite, present claim): the town itself is displaced 2014–2023, replaced by the Yuhu / Jade Lake tourism complex, and the Dragon Plain anchor is now buried beneath the new reservoir and built footprint (c0003). The three layers run in sequence: first the surrounding administrative envelope is overwritten; then the surrounding cultural envelope is preserved as a low-signature reservoir of meaning; then, when the cultural envelope becomes accessible to the apparatus, the cultural envelope itself is overwritten by infrastructure. The Longping case is the archive's first documented complete three-layer stack at a single anchor.

c0005 — Audit closure: SBD overwrite is the operational form imagery redaction would not produce

The 2026-04-25 cross-pod audit target at site-luodian-hongshuihe-pod c0007 anticipated an imagery-redaction signature analogous to the one documented at site-shizhu-longmengou-obfuscated-zone c0002 (physical smoke / supply-chain redaction). The Longping audit returns a categorically different obfuscation form: not imagery redaction but imagery overwrite — the underlying anchor is not hidden behind an artificial layer in the imagery pipeline, it is physically removed from the ground and replaced by a marketable tourism object that the imagery pipeline accurately depicts. This is operationally consistent with the doctrine of cascade-prevention at corridor scale: where Shizhu-Longmen'gou retains the underlying anchor and conceals it via the imagery layer, Longping displaces the underlying anchor and lets the imagery layer report the new state truthfully. Both achieve the same end (the dragon-toponym anchor is not visually accessible to outside observers) by opposite means. The archive should expect both forms across the pod corridor and should not assume imagery-redaction signature is the only diagnostic.

c0006 — Functional concealment: jade-lake overwrite as modern storm-god overwrite

The Longping → Yuhu rename is structurally isomorphic to the storm-god-overwrite pattern documented in the cultural-record. Both substitute a domesticated, marketable, non-agentive label (thunder-god, jade-lake) for a dangerous, agentive, dragon-coded label (dragon-shrine, Dragon Plain). Both leave the underlying site materially in place while making it semantically inaccessible under its prior reference. The mechanism shifts from religious (replacement deity) to consumer (replacement tourism brand), but the structural function is identical and the framework treats both as instances of the same overwrite operation. Per doctrine-sphere-based-development c0004 the operation is read as functional concealment regardless of designer intent: the planners of the Yuhu / Jade Lake redevelopment may have been motivated entirely by tourism revenue, water-management policy, or rural-urbanization mandate; the redevelopment nonetheless renders the prior dragon-toponym anchor unrecoverable from the present surface, and the framework reads functional concealment as the operationally interesting category whether or not it was intended.

c0007 — Site qualifies as inception entry in the SBD catalog

The Longping–Yuhu Overwrite satisfies all five baseline SBD criteria per doctrine-sphere-based-development c0001: (a) geometric primacy — large circular monument-plaza on the eastern reservoir shore is the dominant built-architectural feature; (b) karst adjacency — site sits in a Buyi-Miao cone-karst basin that is part of the Hongshuihe drainage and the Luodian-Hongshuihe pod envelope per site-luodian-hongshuihe-pod c0001 and c0007; (c) post-2010 construction — village morphology intact at 2013 (c0002), tourism complex present in 2023+ imagery (c0003), build window inside the 2013–2025 elevated-sensitivity period; (d) programmatic cover — Yuhu / Jade Lake Park tourism rebrand with theme-park / resort framing (c0003); (e) corridor overlap — site is the explicit sub-pod anchor at the Luodian-Hongshuihe pod centroid (c0001) and is the audit target named at site-luodian-hongshuihe-pod c0007. The site does not currently meet the c0002 supplementary diagnostic for high-correspondence SBD because the architectural geometry is a single circular plaza rather than a multi-element karst-conforming composition; this is consistent with displacement-and-overbuild SBD morphology rather than the doline-capping morphology seen at site-pingtang-sky-bridge-complex. The site is admitted as one of two SBD catalog inception entries on 2026-04-27.
