TypeScript 6.x raises TS5101 on `open-sse/tsconfig.json`: `baseUrl` is
deprecated and stops functioning in TypeScript 7.0. It was paired with
`ignoreDeprecations: "5.0"`, which no longer silences it under TS 6 (the
compiler now demands "6.0").
Remove `baseUrl: ".."` and rewrite the `paths` mappings relative to the
tsconfig's own directory, which is how TypeScript resolves them with no
baseUrl set:
"@/*" ./src/* -> ../src/*
"@omniroute/open-sse" ./open-sse -> ../open-sse
"@omniroute/open-sse/*" ./open-sse/* -> ../open-sse/*
`ignoreDeprecations` goes with it — baseUrl was the only deprecated option
it was suppressing.
Verified by diffing the full tsc error set against the previous config (the
base run used `ignoreDeprecations: "6.0"` so compilation proceeds past the
config error, which otherwise aborts type-checking and masks everything):
zero new errors, 28 fewer. All 28 were in `electron/*.js`, which
`baseUrl: ".."` had been dragging into the open-sse program via
root-relative resolution. Scoping the program back to open-sse also moves
`check:type-coverage` from 92.17% to 94.01%; the ratchet direction is up so
the gate passes, and the baseline is deliberately left alone because the
gain is a measurement-scope change rather than new typing work.
The guard test asserts no tsconfig reintroduces `baseUrl` or
`ignoreDeprecations`, and that every `paths` target still resolves to a real
directory — the second half is the part that matters, since dropping baseUrl
silently changes what those mappings point at.
