@orcana/dsh-governor

DSH adapter plugin for the Orcana runtime pack: mounts the framework-agnostic ProgressFactEngine on DSH extension points. Function plugin (name / Config / apply, no default export).

Extension points

Concern	Hook
Observe every tool call	tools/post-execute (waterfall, always next())
In-round repeat reminders	PostToolDecision.additionalContexts (auto-logged as user/message, once per round)
Zero-progress escalation + forced continuation	agent/turn-stopping + agent.steer(), bounded by maxForcedContinuations
User interjection reset	agent/pre-step (user-source messages reset chains and the budget)
Verification-state snapshot	systemPrompt.context (durable user-role snapshot, orcana:verification-state, order 250)

Translation contract

toEngineEvent is the single DSH→core translation used by both the live listener and translateSessionEvents (session-log replay): normalized command, exit-code marker recovery, background-ack exclusion, mutation flag. Replaying a session log through ProgressFactEngine.rebuild reproduces the live engine state — covered by tests.

Config

governor.enabled / mode (observe | warn-steer | enforce) / zeroProgressThresholds / fingerprintWindow / inlineRepeatTools (default read/bash/search, aligned with the coordinated repeat-tool-reminder exclude); evidence.enabled / freshness / verifyCommandPatterns; completion.mode / maxForcedContinuations; tools.disclosure / defaultProfile. Every field validated by schemastery with defaults; the benchmark treatment patch overrides them via !!js process.env.ORCANA_* ablation knobs.

Known Limitations

• Bash non-zero exits are reported in the result text, not as isError (the exit-marker contract); receipts parse the marker.
• Background bash acknowledgements carry no terminal exit status and are excluded from verification.
