v0.1.0-rc.7

Popper v0.1.0-rc.7 — session-event compatibility (old hosts no longer crash)

Popper is a DeepSeek Harness plugin (not an MCP server, not a standalone CLI): it mounts into a harness profile as a cordis layer, runs inside the harness's own agent loop, and gates real sessions for better development quality.

What changed since rc.6

• Event compatibility root fix: the falsification ledger event (falsification/ledger) is now written with the session-event envelope's ignorable: true marker. A host whose event vocabulary does not include the type skips the ledger rows and loads the session normally instead of refusing the whole log (SessionFormatUnsupportedError).
• Session.append() gained an official ignorable writer option (host change in deepseek-harness packages/core/session); before this, downstream plugins could not mark events skippable at all.
• Event vocabulary (KNOWN_SESSION_EVENT_TYPES, docs/persistence-catalog.md) now registers falsification/ledger; regenerated via pnpm run verify-persistence-catalog.
• Product positioning stated up front: a DeepSeek Harness plugin, not MCP.

What this means for users

• If your harness knows the event type: ledger is interpreted in full (same as rc.6).
• If your harness is older: history loading no longer crashes — the ledger rows are simply skipped.

dsh-popper 0.1.0-rc.6

Stop retrying. Start falsifying.

v0.1.0-rc.6 adds install visibility: the mode status banner is injected once per session on the first tool call (Popper armed (strict). Gates: ... / Popper observing: ...) — an installed plugin is never silently inert.

Blind retry is now forced falsify-and-revise, every step recorded in an append-only SHA-256 evidence ledger. hypothesis → deterministic gate → ≥2 mutually exclusive replacement hypotheses, no falsified experiment reused.

Install:

• dsh plugin --profile demo add github:1473382/dsh-popper
