Section 7 — Architecture and Engineering

CANON SUBORDINATION — this document is PROPOSAL-TIER: it serves canon and never outranks it.
The canon: the CVD · the T1 foundation docs · the T0 registries (registries/) · the spine
(docs/spine/CH_*.md) · the region pages (_source/02_Tier_2_Region_Pages/). Authority order: docs/DOC_MAP.md § 0.
Canon served: NONE FOUND — this document cites no canon anchor anywhere in its body.
Do not build from it alone: open the spine node (docs/spine/CH_NN.md), the region page
(_source/02_Tier_2_Region_Pages/), and the T0 registry your work targets, and derive from those.
READ THAT CANON FIRST — open it and derive from it before you build anything from this document.
If this document disagrees with canon, CANON WINS and this document is the defect — fix the
document, never the canon. Nothing here is applied until it is ratified into canon.

REAL cultural architecture is reference-built, never raw-generated (§17.1); generation is sanctioned

for fantastical/vril structures only. This chapter is unusual in carrying TWO unrelated building

traditions inside one region page, and the section's first discipline is that they stay unrelated.

The Batak highland great-house is a carved timber structure built as a body, warded by figures, and

raised on a day chosen by divination. The Javanese monument-country works are dressed volcanic

andesite raised as cosmological geometry by a court-and-monastery apparatus. Neither explains the

other, neither is a stage of the other, and the page never uses one to fill an evidence gap in the

other. The one reception history the processed record does support is narrow and one-sided: an

Indic vocabulary-and-ornament history documented for the BATAK material alone — Sanskrit-derived

words and motifs received through the strait trade and re-authored locally on Batak carving. The

harvest carries no equivalent documentation for the Javanese monuments, and this page borrows none:

no Indic-reception claim is made about them here on Batak evidence.

The second discipline is evidence honesty, because the two traditions are not equally documented in

the corpus. The Batak building material below is grounded row by row in the region's own audited

harvest. The Java-monument material is spine-and-canon carried: none of the region's processed

sources documents Borobudur, Prambanan, or the Palembang port works, and Section 16 already records

that gap and the unfiltered-query leak that produced it. So the monument paragraphs restate exactly

what the spine sets and author no new measurement, panel count, or construction claim on top of it.

An honest gap is better than a back-filled citation.

Anchor discipline for this section, recorded once so a later verifier does not read a correction as

drift. SRC_00152's page anchors are print pages as printed and are cited unchanged. SRC_00226's

stored anchors run print = PDF − 2, and the single anchor used here (p. 19) is print. SRC_00446's

stored anchors are PDF indices with print = PDF − 1 by the audit's programmatic check across

twenty-six anchors; rather than relabel them one at a time in page text, this section cites that

record by short title without a page number until the anchor space is corrected at the record, and

the relabel is queued to Section 16 as an open item.

The Batak great-house is built as a body

The structural logic of the Batak great-house is not decorative iconography applied to a frame. The

long support beams, the pandingdingan, are the serpent Naga Padoha's body, and separately carved

singa heads are tenoned to the beam-ends as the creature's face, so the finished street-facing

facade is one composite guardian — water buffalo, horse, and serpent-dragon fused — watching the

village lane [SRC: SRC_00446 — Art of Island Southeast Asia] · SUBSTRATE. The singa is carved at

monumental scale on the house and in miniature elsewhere, on horn stoppers and masks, and it

signifies power, protection, and prestige in the same register at both scales.

Three things follow for the build, and all three are buildable now.

tenoned at the beam-ends is a modular art pipeline: one beam set, a small family of singa head

variants, and per-house variation from combination rather than from bespoke sculpting. It also

gives the animated-guardian staging below its articulation points for free.

caldera and then walks a village street has the connection available without a line of dialogue —

the same being, held under the earth in one place and holding up a roof in another. That is the

show-don't-tell surface this material was made for.

not an enemy, everywhere except the one compound named below.

Above the facade sits the saddle-roofed jabu / rumah bolon, the larger and more ornate houses of

high-ranking families flanking the village street, their gabled peaks crowned with double-horned

water-buffalo trophies [SRC: SRC_00446] · SUBSTRATE. House scale and gable crown together read

social standing off the built environment — a legible-status system the player can learn by looking,

which is worth more to exploration than a nameplate.

Village fabric beyond the great-house carries the same warding logic in smaller components. Sculpted

anthropomorphic wooden figures, gana-gana, stand as household and village protective images; each is

individually named, and many of those names begin with pagar, protective [SRC: SRC_00446] ·

SUBSTRATE. Precision the record insists on: gana-gana names the VISIBLE image animated by an

invisible power, not a benign category standing opposite a malign one, and the page states it that

way. The rice granary belongs to the same warded fabric — the lizard emblem of Boraspati ni Tano,

the earth power who dwells in the ground and manifests as a lizard, is carved on granary doors as

well as on manuscript covers and inside medicine horns [SRC: SRC_00446] · SUBSTRATE. A granary door

is therefore a decorated protective surface with a named power attached to the fertility of what it

holds, and the associated world-rule (lizards are not killed and are given rice offerings) is a

concrete respectful-fauna behavior the region can run without a tutorial.

Era discipline binds this whole subsection. The catalogued objects the record describes are

nineteenth- and twentieth-century examples. The 1200 CE build inherits the FORM and the structural

logic — beams-as-body, tenoned heads, carved and named wards, the crowned gable — and never inherits

a dated object or a dated ornament programme as though it were already standing at the present frame.

The compound that fights back

The one place the built environment turns hostile is the corrupt datu's compound, and it turns

hostile because he made it do so. There the house-guardians have been roused as animated wardens,

and the singa facade itself is the encounter — beams flexing, the paired heads striking — to be

out-maneuvered or dismantled to reach the duel-ground within, feeding the BE_0005 phase-two approach

at samosir_highlands [SRC: SRC_00446] · SUBSTRATE. This is the ruled bold case and it is staged

bold: a tradition's own guardian creature becomes a boss rather than being protected into

invisibility. The animation mechanic is the tradition's own, the boss is the singa facade and never

the honored Naga Padoha it embodies, and the hostility is walled to one corrupt individual's

compound while every villager's house on the approach stays inert, protected, and un-enterable as a

target. The substance by which such figures are roused is Section 5's and Section 6's material and

is not detailed here.

Building by the calendar: when a house may be raised

Construction in this region is scheduled, not merely resourced. The datu is consulted to choose the

day to build a house, to marry, to plant rice, to begin a journey, or to fight a battle [SRC:

SRC_00226 — The Power of Writing: Batak Manuscripts, p. 19] · SUBSTRATE. That single attested line

is the section's strongest tie into the chapter's centre of gravity: literacy and divination are not

an ornament on this culture, they are the scheduling layer of its material life, and the raising of a

house frame is gated on a correct read rather than on a full material bar.

Build consequence, stated as a design obligation and not as a promise about another section: any

construction, repair, or raising activity offered in this region routes its timing through the

oracle read rather than a timer, and the read itself — the porhalaan day-and-month table and its

minigame class — is queued to Sections 5 and 13 and is not authored here. Section 7 asserts only

that the calendar governs the building, which is what the record carries.

The stone tradition at Aek Tarum, and getting its place right

Alongside the timber tradition the North Sumatran record carries a monumental stone one: near-life-

size seated ancestor images and house-roofed anisan grave posts, cut from cadas, the soft volcanic

Toba tuff, and painted [SRC: SRC_00152 — A Malayo-Batak Group of Images near Aek (Edwards McKinnon),

p. 1; p. 5; p. 11; p. 12] · SUBSTRATE. Two hedges from the record survive into the build intact. The

colouring WOULD BE provided by haematite and POSSIBLY charcoal or lamp black — a 1975 observer's

inference from weathered paint, with no sampling and no analysis, so the player is never told the

stone was assayed [SRC: SRC_00152, p. 12]. And the painted stripes on the images' chests, which

represent cloth, are red and black; the woven cloth of the same country is chiefly dark blue with red

and white lines intermixed [SRC: SRC_00152, p. 5; p. 7; p. 12]. Those are two different colour

systems and the distinction is the better craft observation: the carver paints cloth in the pigments

a stone-worker has, not in the dyes a weaver has. The dye craft itself is queued to Section 9 and is

not authored here.

The material fact underneath is real craft knowledge and is worth surfacing to a curious player.

Welded tuff is genuinely soft and carvable, which is what makes near-life-size figures possible for a

highland community without a quarry-and-transport apparatus — and that much a carver of the present

frame knows by working it. The deposit's origin in the region's own deep-time eruption is the L3

layer beneath that craft fact, not part of it [SRC: SRC_00152, p. 1] · SUBSTRATE: held BESIDE the

Batak cosmology as volcanology, never collapsed into it, never as lost-race or ancient-alien

evidence, and never handed to a 1200 CE player as a datable finding. The anti-fringe frame the page

fixes in Section 5 binds here without restatement.

SITING, binding, and the reason this paragraph exists. The images stand at Pasaguan, near modern

Pesaguandolok, on the high bank of the Aek Tarum in the Bandar Pulau sub-district of Asahan regency,

at roughly 2°40′43″N 99°22′41″E, on an old trail running from the coast up toward the southern end of

Lake Toba [SRC: SRC_00152, p. 1] · SUBSTRATE. That is MAINLAND North Sumatra. It is not Samosir;

Samosir is the island inside Lake Toba, a different place, a different community, and a different

position in the coast-and-highland economy. The distinction is load-bearing rather than pedantic,

because siting this material on Samosir credits island Toba-Batak with an Asahan tradition, and the

site's value is precisely that it sits on the seam between the coastal port world and the Toba

interior. Where the build routes this content into the samosir_highlands zone for playable

convenience, that is a canon routing choice and is recorded as one: nothing staged there is ever

cited to this record AS located there.

The absence at Aek Tarum: provenance told straight

The record's honest history is not an addendum to this site; it is how the site is known at all. The

place came to notice because the manager of the Aek Tarum rubber plantation reported it — an estate

formerly under tea and belonging to the Haboko Tea Company. A family group of a mother and two

children had already been removed from the site to the Sungei Bedjangkar Estate, south of Lima Puluh

in Batubara regency, and the whereabouts of that image is not known [SRC: SRC_00152, p. 1] ·

SUBSTRATE. The 1975 visiting party took no measurements and had no satellite fix, so the exact

location of the site is no longer known [SRC: SRC_00152, p. 4], and the condition of what remains is

unknown after that date [SRC: SRC_00152, p. 12].

This ships as ordinary substrate, at full specificity, estate names included. It is also the better

design. The build surface here is an ABSENCE the player can investigate rather than a fourth statue

standing conveniently in the clearing:

its own removed dead, which is the agency in this story and is never routed around.

clearing the grass has taken back. A site nobody can quite relocate is a stronger exploration

object than a marked one, and it is what the record actually reports.

Antagonism, where the player pushes on it, routes through the estate-and-collection apparatus and

never through a community. No corrupt individual is invented to carry the removal; the apparatus is

the cause the record names, and inventing a broker to absorb it would teach the player something

false about how these objects moved.

Java's monument-country: what the page asserts, and what it owes

Borobudur is reference-built and protected: the Sailendra terraced monument, the largest Buddhist

monument in the world, its three cosmological levels (Kamadhatu, Rupadhatu, Arupadhatu), its 1,460

narrative relief panels, and its concentric mandala platforms rising to the empty summit stupa

(Threads 5/7/13/22). At the 1200 CE frame it is encountered in the quiet of its late age — the court

long moved east, the monument in decline and quiet stewardship — with its active devotional height

carried as a backward era-glimpse stratum and the precise encountered site-state pending the

scheduled Miksic check (Section 16). Prambanan, the ninth-century Mataram Shaiva temple-complex, is

likewise reference-built and protected. Candi Sukuh is a fifteenth-century sanctuary on Mt Lawu's

western slope and is reference-built for its forward fluctuation stratum ONLY, never composited into

the 1200 CE present — the era-honesty staging this page already carries and does not relax.

The engineering substrate is the volcanic-andesite stone construction and the mandala-proportion

geometry of the terraces, which seed Trade 2 Mining and Trade 8 Engineering as echoes (the Mining

home roots at Ch 19, Engineering at Ch 27; no trade home base roots in this region). The Palembang

port carries the Srivijayan riverine wharf-and-warehouse works as zone geometry, sized in the Zone

Catalog and no further: the strait network's economics are Section 9's, and no processed source in

this corpus documents the construction of the port works themselves.

What this subsection owes, stated plainly rather than papered over. Every monument claim above is

carried from the spine and the tier docs, not from this region's processed harvest, and the depth

pass is gated on the Miksic (Borobudur) and Coedes (Srivijaya) acquisitions Section 16 already

lists. Until those land, this section authors no new dimension, proportion, block-count, joinery, or

construction-sequence claim about Borobudur, Prambanan, or the Palembang works, and it does not

borrow Batak building evidence to describe them. The verify-list entries are queued to Section 16.

Ornament history, kept in its lane

The singa's name comes from Sanskrit simha, lion, and naga from the Sanskrit for snake, received

through the era's Indic contact and re-authored locally into a creature that is buffalo, horse, and

serpent-dragon rather than a lion at all [SRC: SRC_00446 — Art of Island Southeast Asia] ·

SUBSTRATE. That re-authoring is the region's strongest anti-hyperdiffusion exhibit and the page uses

it as such: reception with genuine local authorship, and the source's own hedge honoured — local

elites importing forms, never a civilizing wave arriving. The cross-regional LINK row that formalizes

this reception is queued to Section 15 and is not asserted here as landed. What Section 7 takes from

it is narrow and material: a carved motif on a Batak beam-end has a documented word-history that a

research-minded player can follow, and following it leads to trade and court adoption rather than to

a lost teacher-civilization.
