#1047: JSON.parse("null") returns null without throwing, so every hook's parse guard passed it through and the first data.xxx access threw a TypeError. Bare main() turned that into an unhandled rejection -> exit 1 -> host reported 'hook failed' on every affected tool call. All 13 hook entrypoints now guard non-object payloads before dereferencing and wrap main() in .catch() to fail closed (silent exit 0).
#1057: mem::context and api::context filtered candidate sessions by project only, leaking cross-agent observations/summaries under AGENTMEMORY_AGENT_SCOPE=isolated. Now applies the same agent-scope filter as mem::search (#817); api::context, api::session::start, and event::session::started forward agentId.
Also: bump 0.9.28 across manifests/deploy/export-import set; refresh stale README/AGENTS stats (files/LOC/functions/KV; AGENTS tests 950+ -> 1,428+) and regenerate the website meta snapshot to 0.9.28; CHANGELOG 0.9.28 section; remove the rate-limited star-history chart from README and all 11 translations.
v0.9.19 shipped #495 which chained session-end.mjs after stop.mjs on
the Codex Stop hook. Field-testing surfaced the underlying issue:
Codex fires Stop multiple times within a single conversation (once
per assistant turn), so chaining session-end marked sessions as
completed while later observations were still arriving.
#501 reverts the chain. Stop returns to summarize-only behavior. The
SessionEnd-shaped solution (a dedicated terminate event the agent
sends only once on real session end) tracks at #493.
