docs(triage): stop treating the triage CLI version as the user's build

[derektrimm]

What Changed

The triage playbook no longer treats the context file's Installed version as the version the bug happened on. Section 2 says that line is the version of the t3 binary that ran npx t3 triage. Section 4 asks the user which version, device, and surface the bug was on before cloning, and tells the agent to read serverVersion from the running server's /.well-known/t3/environment as a local cross-check. Section 6 compares against the version the bug happened on. The bundled copy in triagePrompt.ts is updated to stay byte-identical.

Why

Refs #13337. npx t3 triage runs whichever t3 npm resolved, so a user on a desktop nightly got a context file saying 0.0.42, and the agent diagnosed against the wrong source tree. This is the first of the two steps in the triage: old CLIs fetch the playbook from main and follow it, so this takes effect without a release. Renaming the context line and recording the probed server version in the next CLI is the second step and is not in this PR.

• I explained what changed and why

Summary by CodeRabbit

• Documentation
  • Clarified that the version and release tag in a context file identify the command-line tool that created it, which may differ from the affected app or service.
  • Guidance asks for the affected version, device, and app surface before checking source code, and compares any available server version with the user’s answer.
  • Source checks and release comparisons use the version where the issue occurred.
  • Update steps should match the affected build; the command-line launch method does not necessarily indicate how the app or service was installed.

🟡 Medium cli/triagePrompt.ts:109

For desktop/service reports, the update advice targets the triage CLI instead of the affected installation, so a user can remain on the buggy desktop or service build. launchedAs only identifies how triage was started (for example, npx t3 triage), not how the affected app or service is installed; compare against the user's CLI version instead.

Suggested change

	fixed in a release newer than the version the bug happened on: compare versions,
	read release notes and recent commits touching the relevant code.

Fixed in a6dda95, though not with the suggested revert, which would bring back the CLI-version confusion this PR removes. Section 6 now asks for update steps for the build the bug happened on, and notes that CLI launched as only records how t3 triage was started.

🟠 High cli/triagePrompt.ts:56

The clone command can use the older CLI's context-file <release-tag>, so running npx t3 triage with an older CLI against a newer reported desktop/service build clones the wrong source tree. Derive <release-tag> from the version reported for the bug instead of the context file's CLI-derived value.

[derektrimm]

Fixed in a6dda95. The context file's Release tag for this version line comes from the same CLI version, so section 2 now names it alongside Installed version, and section 4 says to clone v plus the version the bug happened on, not that line.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — This is a small, synchronized update to existing triage-agent guidance and does not alter product runtime, schemas, deployment, or sensitive paths. Unresolved findings still identify risks around selecting the affected version for source checkout and update advice.

📝 Walkthrough

Walkthrough

The triage playbook and CLI prompt clarify which version the context file identifies, ask where the bug occurred, and use the affected version to select the source clone and guide release checks and update steps.

Changes

Triage version identification

Layer / File(s)	Summary
Identify the incident version .github/triage/PLAYBOOK.md, apps/server/src/cli/triagePrompt.ts	The instructions clarify that the context file’s installed version and release tag identify the binary that wrote it. They ask which version, device, and surface experienced the bug. If a server is running, they compare its serverVersion with the user’s answer. The source clone uses the v-prefixed tag for the affected version.
Compare releases against the incident version .github/triage/PLAYBOOK.md, apps/server/src/cli/triagePrompt.ts	The newer-release check uses the version where the bug occurred. Update guidance applies to the affected build and clarifies that CLI launched as describes how triage started.

Merge Risk: 🟡 Moderate · up to a6dda

A version reported with a v prefix can send triage to the wrong source, making the diagnosis unreliable. Accept both version formats before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to a6dda

The new server-version check is advisory, while the affected version comes from the user. There is a limited risk that an outdated or altered local server address could direct the check to the wrong endpoint. The guidance still requires approval for fixes and writes.

Retained concerns

• Low · security · inferred: The new server-version check can be directed to an origin reported by stale or altered runtime state; PID liveness alone does not bind that origin to the running server. The response is advisory, limiting the consequence of a wrong endpoint.

Security review details

Security Blast Radius

• inferred — The added endpoint request expands the individual triage agent session's network targets to the origin reported in local runtime state. Evidence does not establish a broader service or tenant exposure.

Trust Boundaries and Controls

• observed — Normal runtime-state creation constructs an HTTP origin from the configured host and port. On read, the origin is decoded as a string; triage's liveness check tests the PID, not whether that process serves the recorded origin.

Resilience and Maintainability Implications

• observed — The added version observation does not authorize writes or fixes; the playbook retains explicit approval for those actions and separates a requested fix clone from the diagnosis clone.

Hardening Proposals

• proposed — Before directing the agent to fetch the endpoint, validate or independently confirm that the reported origin belongs to the intended running server; continue treating its response only as corroborating data.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Normalize the affected version before selecting a tag.

If the user reports v1.2.3, prefixing that answer with v selects vv1.2.3. The clone then falls back to main instead of the affected release. Accept both 1.2.3 and v1.2.3 when forming the tag. Apply the same wording in apps/server/src/cli/triagePrompt.ts.
