Capability Source Matrix

Date: 2026-07-10 Stage: Core business capability roadmap Evidence index: docs/source-discovery/2026-07-09-n12-pre-zyl-index.md Schema notes: docs/source-discovery/2026-07-09-n12-pre-zyl-schema-notes.md

Source priority

1. Existing bridge / API / local service.
2. Local data, log, cache, or database source.
3. UIA helper source through C# WinHelper.
4. Network/protocol source.
5. Mock source for tests only.

MCP tool	Primary source	Fallback source	Evidence file	Decision status	Next implementation slice

isphere_search_contacts	bare sender/receiver JIDs extracted from normalized log-backed messages loaded from configured PacketReader file or directory source	validated copied MsgLib.db tables: TD_Roster, TD_CustomEffigy, tblRecent, tblChatLevel, tblPersonMsg; decrypted roster/contact stanzas from Smark.SendReceive; UIA helper source if display names are still missing	docs/source-discovery/2026-07-10-msglib-readonly-schema-extraction.md; internal/isphere/contacts_test.go; internal/tools/isphere_contacts_test.go	C34 documents optional MsgLib contact display enrichment; R2 adds deterministic exact-match-first ranking, case-insensitive de-duplication across log/MsgLib candidates, and preserves source/raw_ref	core contact search complete; optional richer fields later
isphere_search_groups	decrypted PacketReader.ProcessPacket type="groupchat" stanzas and conference/MUC JIDs loaded from configured PacketReader file or directory source	validated copied MsgLib.db tables: tblMsgGroupPersonMsg, TD_WorkGroupAuth, tblRecent; UIA helper source if group display names are still missing	docs/source-discovery/2026-07-10-msglib-readonly-schema-extraction.md; internal/isphere/groups_test.go; internal/tools/isphere_groups_test.go; C9 ignored-log scan: PacketReader 86 groupchat/86 conference hits; Smark 24 groupchat/658 conference/631 muc hits	C34 documents optional MsgLib group display enrichment; R2 adds deterministic exact-match-first ranking, case-insensitive de-duplication across log/MsgLib candidates, and preserves source/raw_ref	core group search complete; optional member/owner hierarchy later
isphere_receive_files	decrypted PacketReader.ProcessPacket file-transfer message stanzas via internal/isphere.ListFilesFromMessages and isphere_receive_files list mode; configured PacketReader file or directory source; zyl\importal\<hash> cache entries remain unlinked	MsgLib TD_ReceiveFileRecord safe metadata through explicit copied-DB path; decrypted Smark.SendReceive and SaveToDB traces for file-reference reconciliation; future UIA/client connector for download	docs/source-discovery/2026-07-09-n12-pre-zyl-schema-notes.md#c12-file-transfer-evidence-precheck; docs/source-discovery/2026-07-10-file-download-mapping-precheck.md	C22 verifies safe file-list contract args; R3 confirms list metadata is available but no validated message/file-record-to-cache-file mapping exists; R4 remains blocked	R3b file cache mapping diagnostic
isphere_send_message	none validated yet	existing bridge/API/local service preferred; UIA write connector only after internal-sandbox action evidence; network/protocol connector only after protocol discovery	docs/source-discovery/2026-07-10-send-message-source-precheck.md	C15 blocked: contract exists, but no committed bridge/API/local service, helper write op, UIA action chain, or protocol connector is validated	R5 send-message connector discovery
isphere_send_file	none validated yet	depends on send-message connector plus outbound file/upload evidence	docs/source-discovery/2026-07-10-send-message-source-precheck.md	blocked behind isphere_send_message connector selection and file upload/source policy	R7 send-file connector discovery

Stage C entry rule

Open implementation only for the selected row whose evidence maps concrete fields to the MCP output contract. After Stage B2, isphere_receive_messages satisfies the entry rule through decrypted PacketReader.ProcessPacket XML shape.

Stage C first slice recommendation

Start Stage C with a narrow log-backed isphere_receive_messages source abstraction:

1. Implement DES/CBC/PKCS7 line decryption for IMPP.Util.Log.LogSecurityPolicy format.
2. Implement a parser for decrypted PacketReader.ProcessPacket XMPP <message> stanzas.
3. Normalize only redacted test fixtures into message structs first.
4. Add the MCP tool registration after the parser/source abstraction passes tests.

Deferred source work

MsgLib.db has a validated copied read-only open path through the bundled 32-bit System.Data.SQLite.dll and password 123. C27 adds MsgLibReadSidecar as the bounded x86 .NET reader boundary, C28 adds the Go internal/msglib process client, C29 adds bounded display_entities extraction, C30 wires it as optional contact/group MCP enrichment, C31 proves real copied-DB MCP enrichment with sanitized output, C32 reuses it for receive-message display fields, C33 proves that receive display path through a real copied-DB MCP smoke without printing entity values, C34 documents the operator setup/verification path, C35 maps MsgLib message tables to receive-message contract fields without reading row values, C36 adds metadata-only message_sources readiness, C37 defines the bounded DB-backed receive-source design, C38 implements sidecar/Go-wrapper list_messages with sanitized verification, C39 adds a Go adapter from MsgLib list results to the receive-message domain model, C40 adds explicit tool-level msglib_readonly source selection, C41 wires env-configured explicit MsgLib receive with optional sanitized smoke, R1 documents source reconciliation keys, and R2 hardens contact/group search ranking and de-duplication. The active roadmap is docs/superpowers/plans/2026-07-10-core-business-capabilities-roadmap.md; next step is R3 receive-file download mapping precheck.
