Implement Advanced Ecaz Loyalty with public card inspection

Before genuine Advanced Ecaz Traitor dealing, randomly set aside one of the five
native Ecaz cards face up for the game. Store its owner and exact identity once;
exclude it from the initial deck, Tleilaxu Face Dancer setup and Nexus replacement
universes. Do not change leader custody or add choices, payment or Karama windows.
Absent markers preserve older already-dealt saves without taking held cards away.
Validate owner, timing and distinct physical custody before actions, normalization
and projection. Expose a detached public card identity, never private deck order.

Show the named card, portrait and enlarged Traitor inspection above the table.
A dedicated Loyalty context explains public set-aside custody and cannot-call
rules; browser review caught and fixed the generic held-Traitor guidance.
Add internal help, checklist, shared Advanced faction text and source documentation.
The official page8 requirement and page16 noKarama entry support the effect;
relative pre-Traitor prediction/skill sequencing is an explicit composition.
Gated Skills/Ecaz and Moritani assassination/Ecaz are not certified.

Twelve new cases plus related regressions cover candidate selection, immutable
invalid-state rejection,2..6 genuine deals, Basic/noEcaz, completed Tleilaxu setup,
Harkonnen/Tleilaxu Nexus draws, full physical census, detached public views, all4
legal AI setups, JSON continuation, legacy custody and public rendering.
Independent review found no material issue after genuine setup/legacy test fixes
and the focused inspector correction.50 related focused cases pass. A mistyped
filename filter failed closed before the corrected union ran successfully.
Types, lint, all 5012 offline tests, production build and 49 HTTP tests
pass on stable source. Earlier type/lint findings were corrected before this run.

Six genuine faction-game samples finish with no rejected actions and repeated
JSON restoration: CHOAM Basic1054/Advanced225 actions, Ecaz Basic91/Advanced245,
combined Basic476/Advanced704. Existing physical Treachery/force custody checks
pass; focused Loyalty tests cover expansion Traitor census. These bounded legal
samples are not strength calibration or complete expansion acceptance.

Browser QA created a fresh Ecaz/Easy Harkonnen ready lobby and initialized its
Advanced setup before dealing using backup and CAS. Bindikk Narvi was public
before choices and remained excluded through actual human Traitor/force setup,
Storm and refresh. The saved human Traitor is Beast Rabban; a pointer action just
after viewport reset differed from its intended Feyd target, so exact-target
pointer acceptance across viewport changes is not claimed. Ordinary source
bindings remain name/ID-specific. One hand card,12spice,14reserves and the pending
Storm dial restore; both public projections agree and saved seat records match.
The Loyalty inspector shows correct card-specific guidance; Escape restores focus.
At390px its panel has no horizontal overflow,16px text and44/48px controls; the
expanded scroll body fits342px. Internal help opens its complete checklist topic.
Normal viewport restored. Screenshot capture timed out; full visual, long-inspector
keyboard and broader module acceptance remain open.

All 1539 pre-existing rooms, 3259 human seat records and
auxiliary rows remain unchanged. SQLite integrity and foreign keys pass.
Only isolated QA/HTTP fixtures add rooms. No server restart, database reset,
migration, recurring automation, AI strategy change or mode/publication gate change.

 | --- | --- | --- |
+| Ecaz Loyalty | Before initial Traitor dealing, randomly set aside one native Ecaz card face up permanently. No Karama effect; no change to its leader disc. Resolving after existing pre-Traitor setup is an explicit sequencing composition. Older dealt saves are not retrofitted; combined Skills/assassination rosters remain gated. | [Official sources and runtime](ECAZ_LOYALTY.md) |
 | Sapho battle order | First/last reorders remaining Battle-phase choosers at clean boundaries. Phase priority persists through aftermath; actual legal pairs determine eligibility. Separating the chooser from physical attacker/tie advantage is an explicit implementation interpretation of the card's distinct alternatives, not a dedicated FAQ ruling. Last does not prevent others from choosing the holder as an opponent. | [Runtime scope and source interpretation](SAPHO_BATTLE_ORDER.md) |
 | Harass & Withdraw | Either slot but neither category; private Prescience answers null. Return uniquely determined own undialed physical forces before weapon losses, canceled by an opposing successful Traitor. Mandatory after-use discard overrides winner retention. Explosion ordering and own-Traitor disposal are explicit timing/specificity inferences, consistent with the recorded Planetologist precedent. | [Runtime and sources](HARASS_WITHDRAW_RUNTIME.md) |
 | Expansion-faction setup | Selecting Ecaz/Moritani factions does not select their independent three-card variant. Ordinary decks contain 33/35/47 cards; Richese's ten-card cache stays separate. Ecaz allocates six total forces within Imperial Basin sectors 9–11, retaining fourteen reserves. Flexible sector allocation is the literal printed territory constraint; Fremen→Ecaz→Advanced BG order is an implementation inference, while Moritani-last is printed. | [Source and profile contract](EXPANSION_FACTIONS_PROTOTYPE.md) |
