Summary of ChangesHello @aguxez, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request enhances the server's transaction handling by introducing a mechanism to process declined card transactions. The immediate user-facing change is the implementation of push notifications, which will inform users instantly about rejected purchases. Although the foundational code for recording these declined transactions as user activity has been added, this specific database logging functionality is temporarily disabled, pending the development of corresponding user interface elements.

In @server/hooks/panda.ts:
- Around line 955-998: Remove the large commented-out DB logic inside
handleDeclinedTransaction and track the work in your issue tracker: create an
issue describing the pending UI changes needed to handle declined transactions
and include its ID; then replace the commented block with a single-line comment
in handleDeclinedTransaction referencing that issue (e.g., "See ISSUE-1234:
enable declined-transaction persistence once UI supports it"). Ensure the rest
of the function (push notification and error capture) remains unchanged.
- Line 965: Replace the existing comment "// TODO: Enable once UI has proper
designs to handle declined transactions in activity" with the coding-guideline
compliant format: use uppercase tag, a single space, and a fully lowercase
comment body (e.g. "// TODO enable once ui has proper designs to handle declined
transactions in activity"); update the line containing that TODO comment in the
server/hooks/panda.ts hook to remove the colon and capitalize only the TODO tag.

Learning: In the exactly/exa repository, allow and require empty changeset files (containing only --- separators) when changes are not user-facing and do not warrant a version bump. This is needed because CI runs changeset status --since origin/main and requires a changeset file to exist. Ensure such empty changesets are used only for non-user-facing changes and document the rationale in the commit or changelog notes.

@coderabbitai the hooks panda will be sending notification messages to users and this is is super import because it will model the concept and confidence they have in the company so i need a deep research. Please analyze every possible flow of the panda hook and tell me all the notification messages possibility, their text and line number is triggered |

🟡 Duplicate declined records and notifications when body.id is undefined for "requested" action
When the "requested" webhook has body.id as undefined (allowed by the schema at server/hooks/panda.ts:148), the validateTransactionId fallback uses payload.id (the webhook event ID) as the transaction primary key. Later, the "created" declined webhook arrives with body.id set to the actual transaction ID — a different key. Both rejectTx invocations insert separate records with isNewRecord = true, causing a duplicate push notification and two declined activity entries in the user's feed.
Detailed trace of the duplicate flow
- "requested" fails (e.g. InsufficientAccountLiquidity at line 424) →
rejectTxcalled fire-and-forget at line 462 withpayload.body.id = undefined. validateTransactionIdatserver/hooks/panda.ts:1156returnstransactionId = payload.id(e.g."abcdef-123456").updateTransactionRecordINSERTs a row withid = "abcdef-123456",isNewRecord = true→ notification sent.- "created" declined webhook arrives with
body.id = "31eaa81e-..."(actual tx ID). handleDeclinedTransaction→rejectTx→validateTransactionIdreturnstransactionId = "31eaa81e-..."(different key).updateTransactionRecordINSERTs another row withid = "31eaa81e-...",isNewRecord = true→ second notification sent.
The xmax = 0 guard at server/hooks/panda.ts:1121 only prevents duplicates for the same primary key. With two different keys, both upserts are treated as new records.
Impact: The user receives two push notifications for a single decline event, and the activity feed shows two duplicate declined entries.
