Parent / siblings

Sister of generic CW20 intake #589 / O601-1. Tax classification already exists as ephemeral #601 smoke (scripts/qa/localterra-community-tax-smoke.sh) and crate multitest (make verify-issue-592). This issue is a named second harness for tax-on DEX paths so we never loosen Layer B-lt’s 1:1 detectors.

Related: LocalTerra seed + funding issue (optional target pair); swarm / Playwright issues consume the same market but are not this harness.

Current codebase

Layer B-lt (cw20-codeid-audits/scripts/layer-b-lt.sh) is the generic “honest CW20 on this DEX” script used for 8266, 10184 analogue, 11611, 11619, etc.:

Store/instantiate already happened in Layer A-lcd (layer-a-lcd.sh). Community-tax instantiate retries a special InstantiateMsg with buy_bps: 0, sell_bps: 0 (or SKU-stripped 11619+) so 1:1 rows stay meaningful.
B-lt: whitelist local code id, CreatePair vs EMBER, provide, P2 reserve delta, round-trip Send swap (B7), limit escrow 1:1 (L1), SendFrom swap.
Asserts user_debit == Send amount and pair_credit == amount.
Does not RegisterListedPair. 11611/11619 REPORTs say so explicitly: inbound 1:1 holds; tax classification is crate + #601 smoke.

#601 smoke already does tax-on for pair-direct: register, TaxPreview, sell extra-debit, buy outbound split, launcher SKU, settings invoice, MintControl. It does not cover official-router ≥2hop trader, hybrid, zap, or AutoLP SkimToLp vs a live pair (those were O601-7 residuals). AutoLP is null in that script.

Mixing tax-on math into B-lt would either false-fail honest CW20s or punch a hole FoT mutants can walk through (C589-5).

Why this is needed

We need both questions answered on every community-tax pin (local artifact and LCD 11611/11619):

Tax-off / unregistered (B-lt, keep as-is): pair books the declared amount — same bar as every other listed template.
Tax-on (new named suite): after RegisterListedPair, trader extra-debit / outbound split / official-router trader / AutoLP skim floor hold.

#601 is close to (2) but is issue-specific, skips AutoLP, and is easy to “just extend B-lt” under time pressure. A named script + make verify-… target makes the split durable.

Constraints / guardrails

Do not change B-lt asserts to debit == amount + tax or special-case if community-tax inside layer-b-lt.sh.
Do not RegisterListedPair in generic B-lt.
A-lcd may keep 0 bps for 1:1 instantiate; the tax-on suite instantiates nonzero buy/sell (e.g. 500 bps) or uses the seed-deploy QA token.
Whitelist local store id only. Never columbus-5 11611/11612/11621/8654 from this evidence.
No pair/router FoT math (H-01). Pair credit on sell stays amount.
Pair-direct ignores spoofed Swap.trader; official router honors authenticated trader only when from == config.router; missing trader fail-closes (T592-13).
SkimToLp never from token Transfer/Send (T592-10). Floor 100/200 bps (M610-3).
Known-bad ALPHA 8654 / FoT mutants must stay red on B-lt. Tax-on suite is not a substitute listing gate for other templates.
No mnemonics in cw20-codeid-audits/codeids/.

Recommended direction

Add cw20-codeid-audits/scripts/layer-b-tax-on.sh (name bikeshed OK: layer-b-tax-on, community-tax-layer-b.sh).
Factor shared store/create/register/preview helpers from #601 smoke into scripts/lib/ or cw20-codeid-audits/scripts/lib-tax-on.sh so smoke and the new suite do not diverge.
Inputs (first match):
- Env from seed deploy (VITE_TOKEN_COMMUNITY_TAX_ADDRESS + pair + launcher + AutoLP), or
- Ephemeral instantiate like #601 (nonzero bps, AutoLP on).
Required steps (fail closed, write layer-b-tax-on.json):
- RegisterListedPair (if not already).
- TaxPreview sell matches amount + floor(amount * sell_bps / 10000).
- Pair-direct sell: user extra-debit, pair +amount, sink tax.
- Pair-direct buy: outbound split.
- Provide 1:1 after register (regression vs B-lt).
- Official-router ≥2hop: extra-debit trader; pair→router 1:1; spoofed pair-direct trader does not move a third wallet.
- Missing router trader fail-closes.
- Place-limit Send 1:1 (tax-on must not extra-debit Place).
- AutoLP: factory pair set; SkimToLp respects floor; fake pair rejected.
make verify-issue-XXX (or extend verify-issue-601 with an explicit tax-on step that is not B-lt). Docs: harness/README.md, 11611/11619 REPORT “tax-on suite” row, AGENTS_CW20_CODE_ID_AUDIT.md do not merge into B-lt.
Keep #601 smoke as the ops narrative or thin wrapper around the same lib.

Acceptance criteria

layer-b-lt.sh unchanged in 1:1 semantics; community-tax A-lcd/B-lt still pass with tax off.
Named tax-on script exists, is not a stub PASS, and refuses to run without LocalTerra (LAYER_B_TAX_ON=1 or always-on in its verify target).
JSON artifact records pair-direct sell/buy, router trader, spoof-trader negative, limit 1:1, AutoLP floor.
FoT mutant / 8654 still fail generic B-lt (harness bug if green).
#601 verify still green; no docs tell ops to whitelist from tax-on evidence.
REPORT.md for 11611/11619 mention the tax-on suite vs B-lt split.

Test plan (all paths)

Generic CODE_ID=11619 LAYER_B_LT=1 make verify-issue-589 — still 1:1, no register.
Tax-on ephemeral (no seed): store current wasm, 500 bps, register, all required steps.
Tax-on against seed deploy env — skips store if pins present; same asserts.
Provide after register 1:1.
Sell preview + execute; buy split.
Router ≥2hop with trader; hop pair→router 1:1.
Limit place 1:1 after register.
AutoLP skim success at deep pool; skim revert at hostile spread (tax remains on AutoLP).
Invoice path (if kept in this suite or left to #601): 50 UST1 via launcher.
LAYER_B_TAX_ON=1 without chain — print fail/skip like C589-7, never stub PASS.

Test plan (attack / hack / abuse)

Vector	Expect
Engineer “fixes” B-lt by allowing `debit >= amount`	Reject in review; known-bad FoT would go green
`RegisterListedPair` added to `layer-b-lt.sh`	Reject; tax-on script only
Spoof `trader` on pair-direct to tax a victim	Victim unchanged; `from` extra-debited
Router hop without `trader` on option-2 wasm	Tx fail; suite asserts fail-closed
Permissionless register of a non-factory address	`RegisterListedPair` rejects (T592-9 / D8)
AutoLP pair = random CW20 / inverted factory	Reject (M610-1/7)
Call `SkimToLp` from a mocked token hook	Must not be reachable from `Transfer`/`Send`
Stub `executed: true` JSON without txs	Harness bug (same as #590 M590-6)
Use tax-on PASS to whitelist 8654 or a LocalTerra id on columbus-5	Docs/verify `rg` guards

Verification

CODE_ID=11619 LAYER_B_LT=1 make verify-issue-589   # tax-off 1:1 unchanged
# new target, name TBD:
LAYER_B_TAX_ON=1 make verify-issue-XXX
# or: make verify-issue-601  # must call tax-on script, not only B-lt
cd smartcontracts && cargo test -p cl8y-community-tax-token -p cl8y-community-tax-autolp
# mutants still red:
# cw20_codeid_harness::mutant_a1_fot_breaks_one_to_one

Close when the named script is the documented tax-on gate and B-lt remains the honest-CW20 gate.

Merge note (!1134)

Merged to main as !1134 (36fce44c) after resolving conflicts with !1133/#621. Did not wait for CI; gitleaks failed with ci_quota_exceeded.

Sanity on this tip

make verify-issue-623 docs + B-lt untouched + FoT mutant red + token/AutoLP crates: PASS. Live seed-pin path FAILed:

tax-on: using seed pins token=terra1d73t0…stx9ynr pair=terra1zmh0…cp2t8
tax-on: sell extra-debit + pair inbound 1:1
FAIL: buy user credit 1000026 >= pair debit 1000026 (expected outbound split)

LCD get_config on that QTAX token is buy_bps=500 / sell_bps=500. Manager + treasury are test1. The suite’s sell uses fund_trader (test2 when treasury is test1) so extra-debit holds; the buy still Sends EMBER from TEST_ADDRESS (test1). Manager-exempt buy is 1:1 (#609), so the outbound-split assert cannot pass on the #620 seed path.

Remaining (do not reopen this ticket)

Fix seed-path buy to use a non-manager / non-exempt wallet (or skip/assert-exempt explicitly)
Re-run LAYER_B_TAX_ON=1 make verify-issue-623 on a clean seed and keep the ephemeral path green
Optional: CODE_ID=11619 LAYER_B_LT=1 make verify-issue-589 and make verify-issue-601 (B-lt file untouched)

Tracked on the new post-merge issue for !1133–!1135.
