46-61: ⚖️ Poor tradeoffWebRTC fake's

localDescriptionimmediately in the constructor (Line 49), but realRTCPeerConnectionhas it asnulluntilsetLocalDescription()is called. Additionally, the fake'ssetLocalDescriptionmethod (Line 56) doesn't update thelocalDescriptionproperty.This could mask bugs where production code reads
localDescriptionbefore callingsetLocalDescription. However, for testing basic signaling flows (offer/answer/ICE) where the fake methods return resolved promises, this should be adequate.💡 Optional enhancement for more realistic behavior

In @.claude/agents/coderabbit-fixer.md:
- Around line 60-78: The GraphQL query relying on reviewThreads.nodes and
reviewThreads.nodes.comments.nodes must handle schema differences where
databaseId may be missing/deprecated; update the code that processes
reviewThreads, comments, and Step 7 to fall back from comments.nodes.databaseId
to other available identifiers (e.g., comment.id or
PullRequestReviewComment.fullDatabaseId / node.id) and detect presence of
PullRequestReviewComment fields (path, line) before using them; specifically,
adjust the comment-filtering and ID-capture logic that references reviewThreads,
comments, databaseId, PullRequestReviewComment, and Step 7 so it accepts either
databaseId or alternative IDs and skips reply-posting for cover-letter review
bodies without databaseId.
In @.claude/commands/fix-coderabbit.md:
- Around line 21-25: The lock key generation currently pipes the file path
through `sha1sum` which can fail on systems without that tool; update the lock
acquisition logic used by session-lock.sh (the `acquire` invocation) to compute
the hash portably by trying `sha1sum`, then `shasum -a 1`, then `openssl dgst
-sha1` (or similar fallbacks) and only error if none are available, or
alternatively add a short doc note listing required tooling; modify the code
that builds the `"cr-fixer:$(printf '%s' '<path>' | sha1sum | cut -c1-12)"`
token to use the chosen fallback sequence so `session-lock.sh acquire` receives
a valid opaque gate on all platforms.
In @.claude/hooks/block-destructive-git.js:
- Around line 56-72: The existing FORBIDDEN entry that matches git config only
catches explicit write flags but misses the two-argument write form (e.g., git
config user.name "Alice"); update the FORBIDDEN array by adding a second rule
after the current /\bgit\s+config\s+(--global|...)\b/ entry that detects the
simple write pattern (match commands like git config <key> <value> but not
options starting with -); use a regex such as /\bgit\s+config\s+[^\s-][^\s]*\s+/
with the same human-friendly message like "git config (write)" so simple
key/value writes are blocked alongside the existing flag-based rule.
In `@backend/src/libs/allowedOrigins.js`:
- Around line 16-18: The allowedOrigins array in allowedOrigins.js currently
contains bare IP strings (e.g., '13.228.225.19', '18.142.128.26',
'54.254.162.138') which won't match browser Origin headers; update those entries
to include the scheme (e.g., 'https://13.228.225.19' and/or
'http://13.228.225.19') or replace the array with a regex/function-based origin
matcher used by the CORS/Socket.IO config (locate the exported allowedOrigins
array or the origin-checking function in allowedOrigins.js and adjust the
entries/logic accordingly).

36-45: 💤 Low valuePotential socket listener leak in
never()helper on success path.When the timeout resolves (event never arrived), the
socket.once()listener is not removed. If the event arrives afternever()resolves but before the socket disconnects, the listener callback will execute and callclearTimeout(timer)on an already-fired timer, which is harmless but wasteful. More importantly, this orphaned listener could theoretically interfere with subsequent assertions in the same test if the socket were reused.Since all tests disconnect sockets immediately after, this is benign in practice—but cleaning up the listener makes the helper robust for future use.

actions/checkout@v4 (the steps that currently read "uses: actions/checkout@v4")

Test framework, type-checking, docs, tooling & bug fixes
Hardens Waves for production: adds full test suites and CI-style checks to both packages, introduces backend type-checking, consolidates configuration, writes a
docs/reference set, ports the.claude/agent tooling, and fixes several latent bugs surfaced along the way.Branch:
refactor→main· 57 files changed (+10,875 / −408)Why
The app shipped to production with no automated tests, no backend linting or type-checking, duplicated/drifted configuration, and a handful of latent bugs. This PR puts a verifiable safety net under the codebase and documents how it actually behaves today.
