Copy to `martech-context/stack.md`. Public identifiers only. Credentials are recorded by storage location, never by value. Mark anything not yet confirmed `(inferred, confirm)`.

## Tools

Repeat one block per tool and environment. Group by layer: collection, routing, destinations, storage and modelling, activation.

### <Tool name> (<environment>)

- Layer: <collection | routing | destination | storage and modelling | activation>
- Job: <one line: the decision or workflow it serves>
- Status: <active | migrating to X from YYYY-MM-DD | retiring on YYYY-MM-DD | retired on YYYY-MM-DD>
- Operated by: <role>; change approver: <role>; can publish or change: <roles>
- Account owned by: <company | agency>; company-held admin roles: <count and roles, no names>
- Linked under: <manager account or business portfolio, owned by company | agency, or none>; access last reviewed: <YYYY-MM-DD>
- Identifiers: <container, property, stream, account, customer, pixel or dataset IDs, project and dataset names>
- Data in: <from which senders, by which method>
- Data out: <to which destinations, by which method, how often>
- Agent access: <export path, or MCP server and its read-only mode, or none>
- Credentials: <secret name and where it is stored; never the value>
- Settings that change numbers: <time zone, currency, attribution model and window, consent mode, filters, channel groups; link the decisions.md entry that set each>
- Contract or renewal: <date, only if it drives decisions>
- Last verified: <YYYY-MM-DD> by <export file, tool call or repo scan>; baseline: <inventory/YYYY-MM-DD.yaml, export file name and version, or hash>

Add the lines that apply to the tool's kind. Other skills read these by name.

- Tag manager: serves <sites and hostnames>; server container host: <host or none>; tag gateway: <none | path on own domain | CDN-level>; retired container and destination IDs: <list>

- Mobile: SDKs and versions: <MMP, analytics, messaging>; app IDs per store: <placeholders>

## Data flows

One line per flow. Flag any destination with two senders.

- <source> -> <destination>: <method>, <frequency>, owner <role>
- <web GTM container> -> <GA4 property>: <Google tag>, real time, owner <role>

## Consent

- CMP: <tool>; regions: <list>; Google consent mode: <basic | advanced | not used>
- Approved consent model: see `decisions.md` entry <ID>.

## Context copies

Derived copies of this folder in other tools. Update after any change to the source file.

- <Vendor AI context feature, org or project> | source: <file, metric IDs and version> | copied: <YYYY-MM-DD> | owner: <role>

## Archive

Retired tools stay here with their dates so historical questions still resolve.
