Summary

Create and seed at least one secondary AMM pair for UST1 price discovery on the live CL8Y factory — preferred UST1/vFDUSD and/or UST1/cUSTC — or record an explicit product waiver on #502 / this issue if secondary liquidity is deferred.

Parent track: #502 (Phase 4).
Oracle mint/redeem remains primary via ust1-window (/ust1); AMM must never be presented as the mint/redeem path.

Area	Status
Soft-launch pairs	Gemstone CW20 catalog only (`mainnet-soft-launch-defaults.sh`); no UST1 pairs

Frontend Trade/Swap	Routes via indexer + router; no special-case for UST1 markets yet
#502 AC	“At least one secondary AMM pair … with seeded liquidity — or explicit product waiver”

Window mint/redeem is independent; this issue is only the optional/secondary liquidity venue.

Why this is needed

Oracle window sets the primary peg venue; a secondary AMM pair gives Trade/Swap users price discovery and inventory exit/entry without bridging through Venus for every edge trade. #502 acceptance explicitly requires either a live seeded pair or a recorded waiver so Phase 4 can close without silent scope creep. Indexer/frontend already support new factory pairs once created — the gap is ops/governance create + seed + asset metadata, not greenfield AMM code.

Constraints / guardrails

AMM is secondary — never market as oracle mint/redeem; /ust1 remains primary.
Prefer CW20 code 10184 tokens already whitelisted; do not add code IDs without governance (cw20-whitelist-policy.md).
Native LUNC/USTC cannot be pair assets — use cUSTC (or vFDUSD), not raw uusd.
Pay factory pair-creation fee; use governance/deployer process consistent with soft-launch / multisig norms.
Seed liquidity sized for smoke/discovery — document amounts; avoid implying deep peg defense vs window.
Optional: set_discount_registry on new pairs if fee tiers apply.
If product chooses waiver: write explicit rationale + revisit trigger on this issue and #502; do not leave AC unchecked without waiver text.
Indexer must see factory-provenance pair only (foreign pairs rejected).

Parent #502 recommended direction §A

Recommended direction

Path A — create + seed (preferred)

Product picks pair: UST1/vFDUSD (closest to window) and/or UST1/cUSTC.
create_pair on production factory; record pair address + tx.
Provide initial liquidity (router/pair provide); record tx + amounts.
Confirm indexer discovery + candles/pair list; set asset symbols/logos if missing.
Optional: set_discount_registry; link from /ust1 copy as “secondary market”.
Smoke: small Swap/Trade round-trip on the new pair.

Path B — product waiver

Product owner comments waiver on this issue and #502: reason, what is deferred, revisit condition.
Mark pair AC satisfied-via-waiver; do not create misleading empty markets.

Acceptance criteria

Either (A) at least one UST1 secondary pair (UST1/vFDUSD and/or UST1/cUSTC) created on the production factory, indexed, and seeded with documented liquidity — or (B) explicit product waiver recorded on this issue and #502.
If (A): pair visible on dex.cl8y.com (Trade/Swap/Charts as applicable) + indexer.
If (A): small swap smoke tx recorded; pair is factory-provenance.
Docs/issue comment lists pair address(es), create + seed txs, and seed amounts (or waiver text).
No copy implying AMM replaces /ust1 oracle mint/redeem.

Test plan (happy / functional paths)

Pre-check: both pair assets token_info + whitelist code id 10184; factory fee balance for creator.
Create: create_pair succeeds; LCD/factory query lists pair.
Seed: provide liquidity; pool reserves non-zero.
Indexer: pair appears via discovery; assets upserted with correct symbols.
Frontend: pair selectable on Trade/Swap; quote + swap succeed.
Waiver path: skip 2–5; only documentation AC applies.

Test plan (attack / hack / abuse vectors)

Vector	Expected
Marketing AMM as “mint UST1”	Forbidden in UI copy; `/ust1` remains primary
Pair with non-whitelisted code id	Factory reject / policy forbid
Native `uusd`/`uluna` as pair asset	Factory reject; use cUSTC/cLUNC
Foreign/non-factory pair injected to indexer	`verify_factory_provenance` rejects
Seeded dust market mistaken for deep peg	Document seed size; window remains peg venue
Wrong token addresses in create_pair	Pre-check against Phase 2/3 registry
Waiver without written rationale	AC fails — waiver must be explicit on issue

Verification criteria

Pair address + create/seed tx hashes or waiver comment linked from #502.
Indexer shows pair (A) or N/A (B).
Production UI swap smoke (A) or waiver-only close (B).
#502 secondary-pair AC can be checked.

Implementation update (MR `feat/508-ust1-secondary-amm`)

Path B — interim product waiver (AC)

Recorded in deployments/ust1-secondary-pair/PRODUCT_WAIVER.md:

Reason: UST1 total_supply=0 on columbus-5; soft-launch deployer holds 0 UST1/vFDUSD/cUSTC. Creating an empty/dust market would violate seed/honesty guardrails.
Deferred: live create_pair + seed + indexer/UI smoke on production.
Revisit: when operator wallet holds both legs ≥ seed (default 1e6 raw) after window mint / inventory; then run ./scripts/add-ust1-secondary-pair.sh and replace this waiver with Path A txs.

Same waiver applies to parent #502 secondary-pair AC until Path A lands.

Path A readiness shipped in-repo

Scripts: scripts/add-ust1-secondary-pair.sh, scripts/seed-ust1-secondary-pair-local.sh, scripts/lib/ust1-secondary-pair-defaults.sh
Runbook + invariants U1–U7: docs/runbooks/ust1-secondary-amm-pair.md
Agent skill: skills/AGENTS_UST1_SECONDARY_AMM.md
Verify: make verify-issue-508 (+ VERIFY508_LOCAL=1 LocalTerra seeded stand-in pair)
Frontend: secondary-market copy helpers + CreatePair U1 notice (AMM ≠ mint/redeem)

Acceptance criteria checkoff

Either A or B: Path B explicit product waiver recorded (this comment + PRODUCT_WAIVER.md); Path A tooling ready
If (A): pair visible on dex.cl8y.com — N/A until Path A ops
If (A): small swap smoke — N/A until Path A ops
Docs/issue lists waiver text (and Path A will list pair addr/txs when executed)
No copy implying AMM replaces /ust1 mint/redeem

Merge sanity check (MR !1046 → main)

Verdict: #508 Path B (interim product waiver) + Path A tooling are complete enough to merge. make verify-issue-508 PASS; DRY_RUN=1 ./scripts/add-ust1-secondary-pair.sh confirms inventory block (UST1/vFDUSD balances 0).

Remaining problems / open items

Path A ops still blocked: columbus-5 deployer inventory is 0 — live create_pair + seed deferred per waiver. When inventory exists: run ./scripts/add-ust1-secondary-pair.sh, fill deploy-trace.md, VERIFY508_MAINNET=1 make verify-issue-508, then lift waiver on #508/#502.
UI wiring gap: UST1_SECONDARY_MARKET_BLURB / Trade-Swap helpers are unit-tested and CreatePair notice ships, but /ust1 secondary-market CTAs are not wired yet (depends on #506 landing).
Post-merge hygiene: Update waiver blob links from feat/508-ust1-secondary-amm → main.
CI: test-frontend red with pre-existing unrelated failures (same class as main); not introduced by this ops/docs/helpers MR.

Still open for Path A: inventory → ./scripts/add-ust1-secondary-pair.sh → record pair/txs → lift waiver on #502. Update waiver blob links from feature branch → main when convenient.

Path A seed inventory — approved sizes

Full table + wrap/window notes: https://gitlab.com/PlasticDigits/cl8y-dex-terraclassic/-/work_items/521#note_3690052724

Approved (replaces the 1.0-per-side smoke default):

1,000 UST1 + oracle-sized cUSTC
1,000 UST1 + oracle-sized USTR

Price model: UST1 = $1; P_cUSTC = 1.0 × P_USTC; P_USTR = 2.5 × P_USTC; P_USTC from indexer /api/v1/oracle/price/ustc.

Example at $0.00489550 USTC (2026-08-15): 204,269.226841 cUSTC (6 dp, raw 204269226841) and 81,707.690736390562761720 USTR (18 dp, raw 81707690736390562761720). Re-query oracle at mint time.

Do not seed 1,000 cUSTC / 400 USTR (that is the $1-USTC identity only). Live USTC is ~½¢; that ratio would donate the UST1 side.
