Production boundary/logic .ts is clean of the no-unsafe-* family (gateway
payloads are Schema-decoded), so promote it from warn to error. *.tsx is
exempted: @opentui/solid's JSX namespace types every component return as
error/unknown — a framework limitation, not unsafe app code. Test helpers/
mocks (loose fixtures + async signatures) are exempted too. Remaining warns
are no-unnecessary-condition: intentional defensive guards on untrusted
runtime/gateway data that TS's narrowing can't model.
Promote strictness in ui-tui-opentui-v2:
- eslint: @typescript-eslint/no-non-null-assertion: error (with a test
override block keeping `!` in *.test.ts/tsx fixtures), and promote
unused-imports/no-unused-vars warn → error.
- tsconfig: add noUnusedLocals + noImplicitReturns.
Remove all 24 production `!` non-null assertions by replacing each with
a real guard / default / early-return, preserving rendered behavior:
- gateway/client.ts: read the pending entry once and guard (vs has()+get()!).
- logic/theme.ts: guard the parseHex regex match; `?? 0` on the always-
in-bounds XTERM_6_LEVELS lookups; restructure backgroundLuminance to
branch into a typed tuple and use charAt() for the 3-digit hex expand.
- view/homeHint.tsx: use Solid's <Show>{value => …} callback form to
narrow info().model / info().cwd instead of `!`.
- view/reasoningPart.tsx: guard the regex match before slicing m[0].
- view/statusBar.tsx: read model/cwd/pct into locals + guard; `?? 0` on
the showBar()-guarded context-bar percentage.
- view/toolPart.tsx: guard the single-arg entry; `?? 0` on the
duration-guarded fmtDuration.
Enable type-aware linting in ui-tui-opentui-v2: add projectService +
tsconfigRootDir to the TS files block and switch the preset to
recommendedTypeChecked. Turn ON as ERROR the high-value promise rules
(no-floating-promises, no-misused-promises, await-thenable) and fix the
3 real floating-promise sites in the gateway client (FileSink
write/flush/end are fire-and-forget on a piped child stdin — marked
with explicit `void`).
Defer the cast/unknown family + the noisy type-checked rules to 'warn'
(gate stays green; eslint exits 0 on warnings) for Phase 2, which will
replace the `as`/`unknown` boundary casts with Schema decoding:
no-unsafe-{assignment,member-access,argument,return,call},
no-unnecessary-condition, no-base-to-string, restrict-template-
expressions, no-unnecessary-type-assertion, require-await.
