Review summary: set-bio

Architect review of the refactorer handoff for task set-bio.

Commits reviewed

• fcab46d (specifier): Add Gherkin spec for Set Bio (0x6d05) client write path.
• 01a1676 (coder): Implement Set Bio (0x6d05) client write path — memo-set-bio.js, set-bio-page.js, account/set-bio React components, acceptance handlers, and unit tests.
• 9c5767d462 (refactorer): Refactor set-bio to share profile-text action and page bases — moved byte-limit and profile-store reflection into MemoAction via config (maxBytes, profileMethod), extracted a shared ProfileTextPage base for SetBioPage/SetNamePage, generalized AccountPage._getProfileField, and added byte-counting property tests.

Merged with the prior chain commits (5926db1 specifier backlog update). The unrelated swarmforge.conf specifier-model change carried on the refactorer branch was left out of this review merge.

Architectural findings and fixes applied

The refactorer's structure is sound. MemoSetBio/MemoSetName are now thin config-driven subclasses of MemoAction; SetBioPage/SetNamePage share the ProfileTextPage base, which stays free of UI/network concerns behind injected handler/navigate adapters. UI/Core separation, dependency direction, and information hiding all hold. The client remains the only component touched; no psf-memo-db/psf-memo-indexer changes.

I applied one hardening fix (test addition only; no production code changed):

• psf-memo-client/test/unit/set-bio-page.test.js: added a test asserting the page's in-flight flag (settingBio) initializes to false, killing the sole survivor in the shared ProfileTextPage base constructor.

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/profile-text-page.js — 3/3 killed (new base)
• psf-memo-client/src/services/account-page.js — 3/3 killed
• psf-memo-client/src/services/memo-action.js — 3/3 killed
• psf-memo-client/src/services/profiles.js — 1/1 killed
• memo-set-bio.js, memo-set-name.js, set-bio-page.js, set-name-page.js — 0 sites (thin config wrappers; their logic lives in the fully-killed MemoAction/ProfileTextPage)

The React components (app-body/account, app-body/set-bio, 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)

One structural match reported: MemoSetBio and MemoSetName class shells (score 1.00). This is the expected residual pattern of two config-only sibling subclasses of the same MemoAction base; the structural fingerprint normalizes away the distinguishing prefix, messages, byte limits, and method names. Merging them into a single class would forfeit the distinct protocol constants (0x6d01 vs 0x6d05, MAX_NAME_BYTES vs MAX_BIO_BYTES) the pages rely on, with no runtime duplication to remove. Retained as intentional siblings.

CRAP / cyclomatic complexity (crap4javascript)

All changed functions within threshold (max CC 4, CRAP 4.0, 100% branch coverage on all except the defensive MemoAction.isTooLong guard at 66.7% / CRAP 2.1).

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

psf-memo-client set-bio.feature: 13 discovered, 12 executed, 6 killed, 6 survived.

• Scenario 1 (valid bio broadcast) m1,m2: mutated capitalization of the bio 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 bio rejected) m4,m5: mutated chars still leave the bio 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.

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 48 passing, property 6 passing, acceptance pass (7 feature files), lint pass, build success.

Handoffs sent

• git_handoff priority 00 to coder and refactorer (follow-up review of the architectural changes).
• No specifier handoff: no specification changes in this commit (the set-bio feature-file mutation manifest is tool-generated metadata; the weak-scenario findings are recorded here for the specifier in the durable report).

By architect.
