Adds a new product section comparing COTI's Privacy on Demand pERC20 with FHE-based implementations of the ERC-7984 confidential-token standard. - coti-erc7984/README.md — overview, section nav, and summary table - Six sub-pages: precision and decimals, host-chain deployment, transaction economics, transfer semantics, concurrency, deployed contracts - Listed in SUMMARY.md after Privacy on Avalanche - Cross-linked from the Privacy Portal's privateerc20.sol.md Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Rewrite the section as research positioning vs Zama/FHE: draft-standard stance, on-chain DA, decrypt trust model, and validateCiphertext vs ZK input proofs. Co-authored-by: Cursor <cursoragent@cursor.com>
Stakeholder review: inputProof is coprocessor signatures (ZKPoK stays off-chain), euint64/6 decimals is a cost tradeoff not a hard cap, and the PoD encrypt helper receives plaintext. Replace 404 cotitech-io SDK links with GitBook pages and live coti-io repos. Co-authored-by: Cursor <cursoragent@cursor.com>

Revert PoD, Privacy on Avalanche, and Build on COTI edits so this PR stays scoped to the comparison section. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
coti-erc7984/comparison from stakeholder review and a live Sepolia Zama measurement (@zama-fhe/sdk3.5.1): ZKPoK is ~18.8 KB to the Relayer; hostinputProofis 230 bytes of coprocessor signatures.euint64+ 6 decimals is a cost/precision choice), state that the PoD encrypt helper receives plaintext, add trust-assumption and same-tx vs async public-decrypt rows, and merge the comparison tables.coti-erc7984/only (plus existing GitBookSUMMARY.md/ Privacy Portal nav from earlier commits on this branch). PoD, Avalanche, and Build on COTI pages are unchanged.Test plan
