Review summary: set-avatar-url

Architect review of the refactorer handoff for task set-avatar-url.

Commits reviewed

• 991053a (specifier): Spec Set Avatar URL feature.
• 7bee85a (coder): Implement Set Avatar URL client feature — memo-set-avatar-url.js, set-avatar-url-page.js, account/set-avatar-url React components, acceptance handlers, and unit tests.
• 131d31e (refactorer): Merge coder set-avatar-url implementation.
• 58e21ff01a (refactorer): Deduplicate Memo profile-text actions and add set-avatar-url property tests — extracted a shared MemoProfileTextAction base with a profileTextConfig factory so MemoSetName, MemoSetBio, and MemoSetAvatarUrl each become a thin data declaration, removing the duplicated config and broadcast method; added property tests covering the avatar URL byte limit, round trips, and byte budget conservation.

Merged with the prior chain commits (2eb86e2 specifier backlog update, e321c7f revert of an unrelated specifier-model change in swarmforge.conf).

Architectural findings and fixes applied

The refactorer's structure is sound. MemoSetName/MemoSetBio/MemoSetAvatarUrl are now thin config-driven subclasses of the shared MemoProfileTextAction base, which supplies the config factory and the broadcast-method binding; the three actions differ only in their protocol prefix, byte limit, error codes, and profile-store method. UI/Core separation, dependency direction, and information hiding all hold: the wallet and profiles store are injected, keeping the module free of network/UI concerns behind small adapter boundaries. The client remains the only component touched; no psf-memo-db/psf-memo-indexer changes.

No hardening fix was required. The refactorer's property tests already cover the avatar URL byte limit, UTF-8 round trips, byte-budget conservation, and the over-limit rejection path, and language mutation reports no survivors in the changed source files.

Verification results

Language mutation (mutate4javascript, differential vs manifest, --max-workers 8)

Every changed testable source file is fully killed (0 survivors, 0 uncovered):

• psf-memo-client/src/services/memo-profile-text-action.js — 3/3 killed (new base)
• memo-set-avatar-url.js, memo-set-bio.js, memo-set-name.js — 0 sites (thin config wrappers; their logic lives in the fully-killed MemoProfileTextAction/MemoAction bases)

The React components (app-body/account, app-body/set-avatar-url, app-body) are JSX UI modules the mutation tool cannot parse; per the constitution these environmentally unsuitable UI modules are excluded from mutation testing, and their testable logic lives in the services above.

DRY (dry4javascript)

No duplicate candidates found in src/services.

CRAP / cyclomatic complexity (crap4javascript)

All changed functions within threshold: profileTextConfig CC 1, 100% branch coverage, CRAP 1.0. The three thin action subclasses expose no functions (config-only declarations).

Soft Gherkin acceptance mutation (gherkin-mutator --level soft)

psf-memo-client set-avatar-url.feature: 12 executed, 6 killed, 6 survived.

• Scenario 1 (valid avatar URL broadcast) m1,m2: mutated capitalization of the URL example survives because the assertion echoes the broadcast value from the same example (weak/tautological example-to-assertion connection). Specifier-side feature-quality item.
• Scenario 3 (over-long URL rejected) m4,m5: mutated chars still leave the URL over the 217-byte limit, so rejection is unchanged — genuine equivalents.
• Scenario 4 (byte counter) m9,m13: mutated chars leave the byte length unchanged, so the remaining count is identical — genuine equivalents.

The sibling features touched by the shared-base refactor were also re-verified: set-bio.feature (6 killed, 6 survived) and set-name.feature (7 killed, 7 survived), all survivors being the same capitalization/same-length equivalents or tautological-assertion cases. No implementation changes are warranted; the equivalents are intrinsic and the tautological-assertion cases are specifier feature-quality improvements.

Suite status

• psf-memo-client: unit 74 passing, property 11 passing, acceptance pass (8 feature files), lint pass.

Handoffs sent

• No coder/refactorer handoff: the architect made no functional changes requiring follow-up review (only the durable report and tool-generated mutation manifests).
• No specifier handoff: no specification changes in this commit (the feature-file mutation manifests are tool-generated metadata; the weak-scenario findings are recorded here for the specifier in the durable report).
