Cleanup pass summary (2026-05-21)

Sequential 8-agent cleanup against the working state captured at tag restore/sim-15-15-pass-2026-05-21 (see ../RESTORE_POINT.md).

Each agent did focused research → critical assessment → high-confidence implementation, with the local sim re-verified after each set of commits.

Per-agent results

#	Agent	Outcome	Net LOC	Report
01	DRY / consolidation	Extracted watchMembershipConfirmation helper; collapsed two duplicate watcher procs	nwaku +16 / outer −28 / ld +16	01-dry.md
02	Type consolidation	Dropped duplicate MerkleNode/MembershipIndex/ExternalMerkleProof; collapsed adapter procs	nwaku −32 / outer −20 / ld −32	02-types.md
03	Unused code removal	Removed confirmMembershipLeafIndex + RegisterMemberFunc/setRegisterMemberFunc (zero callers anywhere)	nwaku −66 / ld −66	03-unused.md
04	Circular dependencies	Verified no real cycles in scope; no changes	0	04-cycles.md
05	Weak types	Rewrote misleading "break a cyclic import" comment to reflect the true cross-thread storage rationale	nwaku +3 / ld +3	05-weak-types.md
05B	Weak types re-eval	Typed setGroupManagerRef over concrete OnchainLEZGroupManager; tightened setRlnIdentity's cast-back to the same concrete subtype; removed 3 cast[pointer] from caller sites	nwaku +2 / outer 0 / ld +2	05b-weak-types.md
06	try/catch cleanup	All sites at legitimate trust boundaries; no changes	0	06-try-catch.md
07	Deprecated / legacy / fallback	Removed pre-unified-RPC fallback branch in plugin pollLoop (unreachable after unified get_merkle_proofs shipped)	plugin −6 / ld plugin −6	07-legacy.md
08	Slop / comments	Compressed session-narrative comments across the gifter protocol files, codecs.nim, run_simulation.sh; kept WHY-comments (cross-thread storage, server-must-not-close, root-drift defensive)	nwaku −54 / plugin −11 / ld −54	08-slop.md

Aggregate diff vs restore tag

Level	Net LOC change
outer logos-chat	−47
vendor/nwaku	−154
vendor/nwaku/vendor/mix-rln-spam-protection-plugin	−17
vendor/logos-lez-rln/logos-delivery (loose)	−154
vendor/logos-lez-rln	0 (untouched by cleanup; only pinned pointers)

Net change across the chain: ~−372 LOC, removals dominate. No behavioral changes — every commit verified against the local sim with ALL 15 PASS.

Verification

Run	Result	Source
Local sim after each cleanup commit set	ALL 15 PASS	per-agent reports
Local sim final state	ALL 15 PASS	/tmp/sim_cleanup_08b.log
Testnet slim sim final state	ALL 15 PASS (Kademlia ready in 121s, all 4 mix nodes confirmed, sender published, receiver got 24 events)	/tmp/sim_cleanup_phase3_testnet.log

Items deferred to follow-up

Per-agent reports list their own deferred items. Notable ones worth revisiting:

• JSON params encoder (02): The ad-hoc "{\"configAccountId\":\"...\"}" string-concat encoding of RPC fetcher parameters is intentional — short and matches the wire format. A typed record + encoder would not reduce LOC and would add an abstraction layer between the call site and the wire shape. Leave as is unless wire format diverges.
• Watcher-block doc consolidation (08): The two watcher block doc-comments (mix-node and chat-client paths) describe the same contract. Could be reduced to one-liners that defer to watchMembershipConfirmation's docstring as the single source of truth. Tiny win, easy follow-up.
• feat/sim-rln-gifter-auth-debug branch name in the loose logos-delivery checkout (07): the branch carries the full session's work, not just debug. Rename to feat/sim-rln-gifter-auth for consistency with the nwaku side. Cosmetic.

Restore

If a regression surfaces, restore the pre-cleanup state with:

TAG=restore/sim-15-15-pass-2026-05-21
git -C . checkout "$TAG"
git -C vendor/nwaku checkout "$TAG"
git -C vendor/nwaku/vendor/mix-rln-spam-protection-plugin checkout "$TAG"
git -C vendor/logos-lez-rln checkout "$TAG"
git -C vendor/logos-lez-rln/logos-delivery checkout "$TAG"

(Same commands as in ../RESTORE_POINT.md.)
