25. C25: static .NET wrapper analysis recovered the DAL open path: `HYHC.IMPP.DAL.IMPPDAL` configures `System.Data.SQLite` through `Utilities.Lib.DBSQLite`, sets `DatabaseName` to the DB path and `Password` to `123`, and exposes candidate display/message tables such as `TD_Roster`, `tblRecent`, `tblPersonMsg`, `tblMsgGroupPersonMsg`, and `TD_WorkGroupAuth`.

# MsgLib.db copied read-only schema extraction
|
||||
|
||||
Date: 2026-07-10
|
||||
|
||||
## Question
|
||||
|
||||
Can copied `MsgLib.db` files be opened read-only with the wrapper password recovered in C25, and which schema fields should drive the next business read implementation?
|
||||
|
||||
## Evidence checked
|
||||
|
||||
Ignored C26 artifacts:
|
||||
|
||||
- `runs/offline-evidence-intake/zyl-qqfile-20260709/metadata/c26-schema-probe-x86/`
|
||||
- `runs/offline-evidence-intake/zyl-qqfile-20260709/metadata/c26-msglib-schema-probe-x86.json`
|
||||
|
||||
Probe method:
|
||||
|
||||
- referenced the bundled `System.Data.SQLite.dll` from the extracted iSphere client files;
|
||||
- opened copied `MsgLib.db` files only;
|
||||
- used the C25 recovered password `123`;
|
||||
- forced read-only mode in the SQLite connection string;
|
||||
- queried only `sqlite_master`, `PRAGMA table_info(...)`, and safe target-table row counts;
|
||||
- did not dump message bodies, contact values, file paths, or raw rows.
|
||||
|
||||
## Runtime finding
|
||||
|
||||
- A 64-bit probe failed at CLR/SQLite mixed-mode loading.
|
||||
- A 32-bit .NET Framework probe succeeded.
|
||||
- Successful provider: `System.Data.SQLite`, version observed through the opened DB runtime as SQLite `3.6.23.1`.
|
||||
|
||||
This means the production path should not assume Go can open this DB directly. The practical route is a dedicated x86 .NET read-only sidecar/helper that Go MCP calls through a bounded JSON contract.
|
||||
|
||||
## Open result
|
||||
|
||||
All three copied `MsgLib.db` candidates opened successfully with `Password=123` in read-only mode.
|
||||
|
||||
| Copied DB | Open result | Table count | Notable safe counts |
|
||||
| --- | --- | ---: | --- |
|
||||
| DB A, about 12.2 MB | ok | 13 | `tblMsgGroupPersonMsg=2884`, `tblPersonMsg=2132`, `tblRecent=52`, `TD_SystemMessageRecord=469` |
|
||||
| DB B, about 2.84 MB | ok | 23 | `tblMsgGroupPersonMsg=1048`, `tblPersonMsg=1209`, `tblRecent=80`, `tblChatLevel=105`, `TD_WorkGroupAuth=2`, `TD_SystemMessageRecord=314` |
|
||||
| DB C, about 2.78 MB | ok | 13 | `tblMsgGroupPersonMsg=796`, `tblPersonMsg=1932`, `tblRecent=51`, `TD_SystemMessageRecord=228` |
|
||||
|
||||
The counts above are schema-validation counts only. No row values were extracted into committed docs.
|
||||
|
||||
## Confirmed business schema map
|
||||
|
||||
### Contacts and display names
|
||||
|
||||
Validated tables/columns:
|
||||
|
||||
- `TD_Roster`: `JId`, `Domain`, `Nick`, `Ask`, `Subscription`, `Show`, `Status`, `GroupName`.
|
||||
- `TD_CustomEffigy`: `PersonJid`, `PersonName`, `PersonSex`, `HeadImageSize`, `LocalPath`, `ServerUpdateTime`.
|
||||
- `tblRecent`: `Id`, `PersonId`, `PersonName`, `ActionTime`, `FType`.
|
||||
- `tblChatLevel`: present in the richer DB and already known from C25 model fields as `PersonId`, `PersonName`.
|
||||
- `tblPersonMsg`: `SndPerson`, `SndPersonId`, `RecvPerson`, `RecvPersonId`, `ObjPerson`, `ObjPersonId`, plus message metadata fields.
|
||||
|
||||
Recommended contact display-name priority for a future read source:
|
||||
|
||||
1. `TD_Roster.Nick` by `TD_Roster.JId` when present.
|
||||
2. `TD_CustomEffigy.PersonName` by `PersonJid` when present.
|
||||
3. `tblRecent.PersonName` by `PersonId` for recent conversations.
|
||||
4. `tblPersonMsg` sender/receiver/object display fields as fallback.
|
||||
5. JID-derived fallback when DB display fields are absent.
|
||||
|
||||
### Groups and member names
|
||||
|
||||
Validated tables/columns:
|
||||
|
||||
- `tblMsgGroupPersonMsg`: `MsgGroupId`, `MsgGroupName`, `SessionTitle`, `SessionPersonId`, `SessionPersonName`, `GroupType`, plus message metadata fields.
|
||||
- `TD_WorkGroupAuth`: `SessionID`, `SessionStatus`, `SessionType`, `ApplyInfo`, `GroupJID`, `GroupName`, `SendPersonSex`, `ApplyDateTime`; richer DB also has `ChildGroupJid`.
|
||||
- `tblRecent`: stores group recent entries through triggers using `PersonId = MsgGroupId`, `PersonName = MsgGroupName`, and `FType = GroupType`.
|
||||
|
||||
Recommended group display/member priority:
|
||||
|
||||
1. `tblMsgGroupPersonMsg.MsgGroupName` by `MsgGroupId`.
|
||||
2. `tblRecent.PersonName` by `PersonId` where `FType` indicates group/discussion.
|
||||
3. `TD_WorkGroupAuth.GroupName` by `GroupJID` for work-group authorization records.
|
||||
4. `tblMsgGroupPersonMsg.SessionPersonId/SessionPersonName` for member-name enrichment.
|
||||
5. JID-derived fallback when DB display fields are absent.
|
||||
|
||||
### Receive messages
|
||||
|
||||
Validated tables/columns:
|
||||
|
||||
- `tblPersonMsg`: one-to-one message table, including ids, sender/receiver/object identities, text/body/content/version/read fields, timestamps, and receipt state.
|
||||
- `tblMsgGroupPersonMsg`: group/discussion message table, including ids, sender identities, group ids/names, session title/member fields, message body/content/version/read fields, and timestamps.
|
||||
- `TD_SystemMessageRecord`: system/auth message metadata.
|
||||
|
||||
C27 should not read message bodies yet. The next code loop should first add a schema/display-name sidecar and only later add DB-backed message listing with strict limit/redaction controls.
|
||||
|
||||
### File metadata
|
||||
|
||||
Validated tables/columns:
|
||||
|
||||
- `TD_ReceiveFileRecord`: `ReceiveMsgGuid`, `FileName`, `FileSize`, `FilePath`, `SourceID`, `SourceName`, `FileType`, `SendPersonJid`, `SendPersonName`, `SendTime`.
|
||||
- `TD_SendFileRecord`: `SendMsgGuid`, `FileName`, `FileSize`, `FilePath`, `SourceID`, `SourceName`, `FileType`, `ReceivePersonJid`, `ReceivePersonName`, `ReceiveTime`.
|
||||
|
||||
File download remains blocked until cache/download mapping is separately validated.
|
||||
|
||||
## Decision
|
||||
|
||||
C26 validates the DB path:
|
||||
|
||||
> `MsgLib.db` can be opened from copied evidence with the bundled 32-bit `System.Data.SQLite.dll`, `Password=123`, and read-only mode.
|
||||
|
||||
The project can now move from log-only read support toward DB-backed contact/group display-name enrichment. Because the working provider path is 32-bit .NET, the next implementation should be a bounded x86 .NET sidecar/helper rather than direct Go SQLite access.
|
||||
|
||||
## Next slice
|
||||
|
||||
Loop C27 should implement the first production-shaped DB bridge as a narrow helper/sidecar contract, not as broad message extraction:
|
||||
|
||||
1. Build a committed contract for a read-only `MsgLib.db` schema/display-name sidecar.
|
||||
2. Start with safe operations such as `msglib_self_check` and `msglib_list_display_sources` or equivalent.
|
||||
3. Return only table availability, column availability, and display-name candidate maps with strict limits.
|
||||
4. Keep message-body reads, file downloads, sends, writes, and DB mutation out of scope.

## Loop C27: Bounded x86 `MsgLib.db` sidecar/helper contract
|
||||
|
||||
**Goal:** Turn the validated C26 read-only DB path into the first production-shaped helper boundary for DB-backed display-name/source metadata, without exposing message bodies or adding write behavior.
|
||||
|
||||
**Planned files:**
|
||||
- Modify or create docs that define the sidecar/helper JSON contract.
|
||||
- Optionally create a minimal committed C# sidecar/helper skeleton if the contract can stay narrow and testable.
|
||||
- Modify verification docs/scripts only if an executable smoke is added.
|
||||
- Do not commit `System.Data.SQLite.dll`, copied DBs, raw rows, message bodies, personal values, file paths, or generated probe binaries.
|
||||
|
||||
**Planned behavior:**
|
||||
- Treat the DB reader as a dedicated x86 .NET boundary because C26 proved 32-bit SQLite loading is required.
|
||||
- Start with safe operations such as:
|
||||
- `msglib_self_check`: validates provider load and read-only open against a copied DB path.
|
||||
- `msglib_list_display_sources`: returns table/column availability and limited display-name source counts, not raw message content.
|
||||
- Keep Go MCP as the coordinator and use a bounded process/helper contract for Windows/.NET DB access.
|
||||
- Keep message-body reads, file downloads, sends, writes, hooks, injection, and DB mutation out of scope.

|
||||
- [ ] **Step 1: Define the sidecar/helper contract**
|
||||
|
||||
Write the request/response envelope, allowed operations, path rules, limit rules, and redaction rules.
|
||||
|
||||
- [ ] **Step 2: Decide skeleton vs docs-only for this loop**
|
||||
|
||||
If the contract is stable enough, create a minimal C# x86 sidecar skeleton with self-check only. Otherwise keep C27 as a contract/design gate and make C28 the skeleton implementation.
|
||||
|
||||
- [ ] **Step 3: Update status/matrix/plan**
|
||||
|
||||
Record the implementation boundary and next code slice based on actual C27 output.
|
||||
|
||||
- [ ] **Step 4: Verify and commit**
|
||||
|
||||
Run the appropriate docs/code verification before commit:
|
||||
|
||||
```powershell
|
||||
git diff --check
|
||||
go test ./...
|
||||
powershell -NoProfile -ExecutionPolicy Bypass -File scripts/verify-go-mcp.ps1
|
||||
```

## Self-Review
|
||||
|
||||
- Spec coverage: the plan follows the user's cyclic requirement: plan first, implement one loop at a time, update the next loop after each result, and ask only on blockers.
