+### Verification status
+
+Every criterion above is supported by evidence from the automated test suite,
+the build, or the seeded content itself — no criterion here needed the
+running app to confirm structurally:
+
+1. **Full playable location** — seeded as an `OUTPOST` with four points of
+   interest (hunt, investigate, search, map-out) and its own encounter pool
+   (`vertical-slice.seed.spec.ts`: "seeds the watchpost as a huntable
+   outpost"); local content in `local-location.content.ts`.
+2. **Server-authoritative travel** — the Burned Road ↔ Watchpost connection
+   is seeded both ways at 15 s / 10 % ambush (`"connects the burned road and
+   the watchpost both ways without a gate"`); `TravelService` computes
+   `arrivesAt` server-side and is covered generically by
+   `travel.service.spec.ts`.
+3. **Stronger, distinct pool** — `"gives the watchpost its own encounter
+   pool"` seeds exactly Road Bandit, Raider Scout, Raider Veteran, Burned
+   Hound and the rare Raider Captain; `"marks only the captain as a rare
+   encounter"` confirms the rarity split.
+4. **An enemy combining learned mechanics** — the Raider Veteran carries both
+   `telegraph` (existing, from the Burned Road) and the new `guard`
+   (`"arms the veteran with a telegraph and a guard on different
+   cadences"`); the priority between them is covered in
+   `combat-engine.service.spec.ts`.
+5. **Both bag categories matter** — Scorched Hide is seeded `HIDE`, Raider
+   Warband Mark is seeded `RAIDER_TROPHY`
+   (`vertical-slice.seed.spec.ts`), and both categories were already
+   load-bearing bag mechanics before this slice (Slice 0.7.5/0.9).
+6. **Tier-1 equipment improved** — the Raider Veteran's own loot table adds
+   Plunderer Gloves, Reinforced Leather Jacket and Watchman's Leggings on top
+   of the Raider Warband Mark, and the Raider Scout carries Bandit Hood at a
+   raised chance (`item-content.ts`); the Road Bandit's own table (already
+   present) is left untouched at the same values
+   (`"leaves the road bandit loot table untouched"` pins Bandit Blade at
+   `0.1800`), so the Watchpost's gear opportunities are additive, not a
+   rebalance of the Burned Road.
+7. **Investigation points to the Ash Pit** — the `inspect-watchpost` hotspot
+   carries the §8 clue text verbatim and `discoversLocationKey: 'ash-pit'`
+   (`"points the watchpost investigation at the ash pit"`).
+8. **Ash Pit discoverable without a level gate** — the gate is
+   `requiresDiscovery`, not `minRecommendedLevel`; `WorldDiscoveryService`
+   contains no level check at all. Covered end to end: the hotspot writes the
+   discovery (`local-location-interaction.spec.ts`: `"discovers the route the
+   hotspot points at"`), the map hides/reveals it
+   (`world.service.spec.ts`: `"hides a gated connection until the character
+   has discovered it"` / `"shows a gated connection once it has been
+   discovered"`), and travel itself refuses/allows it
+   (`world-discovery.service.spec.ts` and `travel.service.spec.ts`, both:
+   `"refuses a gated route the character has not discovered"` /
+   `"allows a gated route once it has been discovered"`).
+9. **Merchant/reputation loop continues** — both new trade goods have
+   exchange rules paying Silver and regional reputation, and pay more than
+   their Burned Road equivalents (`"lets Borin buy both watchpost trade
+   goods"`, `"pays more for watchpost goods than for road goods"`). No new
+   code path grants Silver, reputation or Renown directly from a kill; the
+   pack-wide rule (README.md) that only the exchange grants those was already
+   enforced before this slice and nothing in Slice 0.10 bypasses it.
+10. **English content** — every string seeded for the Watchpost and Ash Pit
+    (descriptions, hotspot titles and result text, monster flavour text) was
+    read during this review and is English.
+
+What this status does **not** cover, because it cannot be produced by static
+evidence: actually applying migration `1798000000000` to a real PostgreSQL
+database, confirming the second `db:seed` run is idempotent against real
+constraints, and a hand-played pass through the loop in a browser. Those are
+listed precisely in the implementation notes
+(`0.10-Abandoned-Watchpost-implementation-notes.md`, §7) as outstanding work
+for the project owner.
