docs: BOM/hardware corrections + Valar store links + wiki sync

[daniel-frenkel]

Documentation-only corrections from the confirmed hardware facts (ROPENER-DOC-UPDATE work order, confirmed 2026-07-28). No firmware / STEP / STL changes.

Changes

• Mounting — 3M command strips → five 1" foam mounting squares (BOM-V2.0, wiki Build-Guide, README). Build step now says to wipe the surface clean/dry and press firmly (the squares ship loose with no instructions).
• Arm screw — corrected to M3 × 15 mm button head (BOM-V2.0 was 16 mm; Build-Guide prose was 12 mm).
• 35 mm screw — Build-Guide prose corrected 30 → 35 mm (arm-attach + bottom-join), and the third M3 × 35 mm screw is now documented as the clamp screw that threads into a square nut seated in one arm to pull the arm pair against the drive pulley.
• M3 square nuts — Body Assembly 1 → 3 in BOM-V2.0 (curtain stays 1; total 4). Build-Guide now tells the builder to seat the third nut before the arms mate (the pocket is inaccessible afterward).
• Power adapter — 24 V 1.5 A (was "12 V / 2A+"; dropped the stale "12 V is best" note).
• Product links — every purchasable BOM row now links to the Valar Systems store; all Amazon affiliate links removed. make_bom.py intro text updated to match.
• Wiki mirror sync — docs/wiki-* brought up to the live wiki's own edits (redesigned Home + foam line, Firmware-Guide select: edit, de-emojified sidebar) so the repo mirror is the single source of truth.

The live wiki is being synced separately from this corrected mirror.

Flags (not changed — need your call)

1. Arm screw qty: BOM-V2.0 lists the M3 × 15 mm arm screw at qty 2 (one per arm); the wiki tables say 3. Per your instruction I left the wiki at 3 and left BOM-V2.0 at 2 — but the build prose only places 2 (one per arm), so the third's location is unaccounted. Confirm the real count.
2. Wire nail count: BOM-V2.0 says 3; the old README said "4 small nails." I dropped the count from the README prose rather than guess.
3. arm-to-motor rename (work-order CHANGE 4b): the string appears nowhere in repo or wiki — no-op.
4. README McMaster-Carr mention (prose, "sourced in bulk from places like McMaster-Carr") left as-is — it's a cost illustration, not a BOM link.
5. Glide-tape "available on Amazon" prose in Build-Guide left as-is (glide tape has no Valar SKU). The amzn.to affiliate link in the wiki Installation-Guide is being removed during the wiki sync.
6. Generated docs/dist/ docx/PDF still carry the old data — regenerate with python make_bom.py (needs the toolchain) to refresh the binaries.

Flag #1 resolved (owner-confirmed) + one new flag

Arm-screw qty — resolved. The wiki was right: M3 × 15 mm button head = qty 3 = one per arm (2) + the curtain-pulley screw (1), threaded into the 4th square nut.

Applied (commits d4f0dc8, wiki 95d07aa):

• BOM-V2.0 Body: M3 × 15 button head 2 → 3.
• BOM-V2.0 Curtain: deleted the phantom M3 × 12 mm flat head | 1 — it was the pulley screw misidentified, not a separate part (no store link created).
• Build-Guide pulley-end step + image: pulley is held by an M3 × 15 mm button-head screw into an M3 square nut (was "M3 × 12 mm flat-head").

Confirmed fastener map now reconciles across every table — each of the 4 square nuts pairs with exactly one screw (2× M3×15 arm, 1× M3×35 clamp, 1× M3×15 pulley):

Fastener	Total	Where
M3 × 15 mm button head	3	arm (2) + curtain pulley (1)
M3 × 35 mm button head	3	arms-to-motor (2) + arm-bottom clamp (1)
M3 square nut	4	arm (2) + clamp (1) + curtain pulley (1)
633ZZ bearing	2	one per arm

New flag (pre-existing, not changed): thread-forming/self-tapping M3 × 10 count disagrees — wiki quick-BOM says 23, BOM-V2.0 says 8 (body) + 11 (curtain) = 19. These don't pair with nuts so the pairing rule doesn't pin them; the counts need a physical confirm. Left both as-is pending your word.

Remaining flags resolved (owner-confirmed)

• Thread-forming M3 × 10 screws = 22 total. BOM-V2.0 split Body 8 / Curtain 14 (Body = 4 PCB + 4 wall-plate; the 2 motor-mount screws are machine screws into the motor, not thread-forming). Wiki quick-BOM aggregate 23 → 22.
• Wire nail: removed from the BOM. It was 4, but nails are no longer included in the kit, so the row is gone from Mounting Hardware. README still lists "small nails" only as a user-supplied drywall option (foam is the only "included" item).

All fastener counts now cross-check. Remaining non-blocking item: docs/dist/ docx/PDF still hold old data — regenerate with python make_bom.py.
