fix(aidd-context): source tool-paths claims with dates and URLs

[alexsoyes]

Closes #618

What

Every factual cell in 08-hook-generate/references/tool-paths.md now carries [v] (read in the official docs on 2026-08-11) or [?] (not re-read, unverified). A Sources section lists each page, plus the two URLs that moved and now redirect.

Why

The file stated Codex CLI has no session-end moment. It has one. The claim was wrong and it propagated into a design decision before anyone re-read the source.

The failure is structural: not one cell carried a URL or a date, so nothing distinguished "read in the docs" from "assumed months ago". Auditing a single claim meant re-verifying the whole table. A skill reads this file instead of the vendor docs, so an error here becomes an error in every artefact it generates.

Corrections

• Codex has SessionEnd. Timeout 1 s, 3 s max, and it does not run for subagents.
• Copilot casing is not an alias. It selects the payload format (camelCase fields vs snake_case) and sometimes the event name: agentStop becomes Stop.
• Failure semantics differ per tool, and one denies. A preToolUse handler that exits non-zero on Copilot denies the tool call, so an observer hook that throws stops the agent.
• OpenCode confirmed as plugins-only: no session-end event, no session id in the plugin context.
• Session identifier field names differ across all four supported tools, and no vendor documents whether the value survives a resume, clear, compaction or fork.

Verified against

Claude Code hooks and monitoring-usage, Codex hooks and config-advanced, Cursor hooks, Copilot hooks-reference, OpenCode plugins and config schema. One agent per tool, one page per claim, citations recorded in the dashboard repo at aidd_docs/memory/kpi/probes/03-hooks-et-identifiants-session.md.

Closing: this work stays on the dashboard side. The verified matrix and its sources live in the dashboard repo at aidd_docs/memory/kpi/probes/03-hooks-et-identifiants-session.md. Reopen if the framework reference is picked up later.
