jpmschweitzer cbeadc3184 feat(tooling): grounding overhaul + richer naming palettes (#833)
Substantial quality pass on gemma_naming.py driven by user review of
the first real-mode smoke test output. The earlier run produced names
that read too sci-fi / epic-fantasy / same-y: Aureus, Aetheria,
Stellaris, Nexus, Elysium. Root cause analysis + fixes:

1. Runtime timestamps. The log prefix is now
   `[HH:MM:SS +00h03m]` — clock time plus elapsed-since-start. Gives
   the user an at-a-glance sense of how long the run has been going
   without scrolling back to the banner.

2. System / body headers. When the loop enters a new system it prints
   `── SYSTEM K/N  GJ 71 — Tau Ceti  (hop 0)`. Each body line now
   shows `GJ71c (Threshold)` if the body has a proper_name in
   systems.db, so the log reads like a tour of the reach rather than
   a wall of body_id slugs. Preserved (already-named) bodies now log
   a compact "(skip — N names already set)" line so progress is
   visible even when no inference happened.

3. Prompt grounding overhaul. The old few-shot examples were all
   classical/epic (Wolcott Beck, Nakamura Stream, Ribeiro do Sal,
   Drayton Spine) which biased Gemma 2 2B toward Latin/Greek
   coinages. New preambles use the shape:
       "Settlers named X after themselves, after what they saw, or
        after places back home. Most names are mundane, short, and
        direct — a surname, a compass direction, a feature, a
        practical description. Classical or epic names are rare."
   Combined with grounded example pools, Gemma now produces names
   like "Cooper's Creek", "Western Ridge", "The Highroad",
   "Blackwood Creek", "Dustbowl".

4. Core corridor relabel. The "core" palette inflection was
   "institutional Latin / pan-Anglo / Gateway-era", which pattern-
   matched in Gemma's training data to "make up Latin-sounding
   words" (→ Ardenia, Aurelia, Stellaris). Now it's
   "administrative English / Gateway-era" and the outputs are
   prosaic — Port Dundas, East Ridge, Meridian, Landing.

5. Rotating few-shot example pools. Each feature type now has 5-7
   pools of 5-6 examples each. `_build_prompt()` picks a pool
   deterministically per (body_id, local_id, attempt) so:
   - Same feature always gets the same prompt (determinism preserved).
   - Neighbouring features on the same body get different prompts
     (output variance — the sampler doesn't collapse to a single
     mode when you ask for 16 mountain names in a row).
   - Retries rotate to a new pool, not just a bumped seed, giving
     dedup failures a clean second attempt.

6. Cosmopolitan cultural variety in the examples. Earlier pools only
   showed British/Australian, Korean/Japanese, Portuguese/Swahili,
   German/Dutch/Nordic axes — the four reach corridors. Gemma learned
   "names come in four flavours". New pools span Dutch, Nordic,
   Italian, French, Polish, Hungarian, Czech, Spanish, Russian,
   Finnish, Greek, Irish, Japanese, and British — teaching the model
   that names can be any real Earth cultural register, not just the
   corridor label. The result: actual Dutch names (Egelantier,
   Hochland, Van Damhoeve), actual Nordic (Lundstad, Brygga),
   actual Italian (Borgo Marconi, Piazza Nuova), etc.

7. First-name possessive pools. Per user feedback, settler naming
   includes both surnames ("Cooper's Creek") and first names
   ("Clifford's Bay", "Maura's Run", "Yuki's Pool"). Each feature
   type now has a dedicated first-name-possessive pool in addition
   to the existing surname pool — the two rotate alongside so both
   patterns show up without either dominating.

8. One "classical/Latinate" pool per feature type (≈17% of calls
   given 5-7 pools per type). Keeps occasional Latin flavour without
   making it dominant — the user explicitly noted that replacing
   one pattern with another "is never a clean fix for a randomizer."

9. Earth-name blocklist expansion. The Gemma 2 model reached for
   real European names ("Weser", "Rhine", "Reykjavik") in the first
   real run. Added 21 European rivers (Rhine, Weser, Elbe, Oder,
   Vistula, Loire, Rhône, Douro, Tagus, Ebro, Po, Arno, Tiber, …)
   and 25 Nordic/Eastern European cities (Reykjavik, Oslo, Gdansk,
   Krakow, Prague, Warsaw, Budapest, Belgrade, …). Case-insensitive
   "The <name>" stripping still applies so "The Great Divide" also
   matches "Great Divide".

Combined smoke test after these changes (10 real-mode prompts across
core + west_reach):
  - core:       Port Dundas, The Backbone, Dustbowl, Blackwood Creek
  - west_reach: Egelantier, Hochland, Der Rücken, Lundstad, Klipfjord
  - no placeholder residue, no markdown, no 5+ word outputs.

--shard is gone (dead code since GPU contention killed parallelism).
Resume semantics are still free: re-run the same command and
already-named bodies skip via the preserved path.

"""
gemma_naming.py — Batch-name every empty name field in the reach's
markers.json files using the Gemma 2 voice pipeline (#833, D-191 §4).
Pipeline per body:
1. Load markers.json; identify feature records whose `name` is empty
or null. Hand-authored names are never overwritten.
2. Build a short corridor-aware prompt per feature.
3. Stream the prompts into `sr-voice serve --stdio` (long-lived
subprocess, restarted every --refresh requests to prevent KV-cache
context bleed).
4. Post-process each response: strip quotes, trim whitespace, reject
blocklisted Earth majors, retry with a bumped seed on collision or
on blocklist hit (up to 3 attempts), fall back to a deterministic
palette-driven name on persistent failure.
5. Dedup within (cultural_corridor, feature_type) so two bodies in the
same corridor never ship the same river name; cross-corridor
collisions are allowed (two "Aldren"s on opposite arcs is fine).
6. Write markers.json back (only if any field changed).
7. Sync every touched body's atlas_* rows in systems.db so
`atlas_cities.name`, `atlas_rivers.name`, etc. pick up the new
strings without needing a follow-up generate_atlas.py pass.

# Feature prompt templates — few-shot format with rotating example pools
# ---------------------------------------------------------------------------
# Gemma 2 2B is small and noisy on free-form instruction prompts — it
# loves to echo the prompt back as "[River Name]" / "NAME: ..." /
# "**River: X**" etc. The fix is few-shot: show concrete
# `Style → Answer` examples so the model completes a pattern instead
# of generating to an open-ended instruction.
#
# Two lessons from earlier iterations:
# 1. The examples are the ONLY thing the model actually learns from.
# If they're all epic/classical (Wolcott Beck, Nakamura Stream),
# the model completes in epic/classical register for every body.
# Grounded outputs (Cooper's Creek, West Ridge, Mill Run) require
# grounded examples.
# 2. A single static example set produces uniform output: same prompt
# + similar seeds → similar completions. Rotating through a pool
# of example sets per call injects variation and nudges the
# sampler into different regions of the output distribution.
#
# Each feature type has a POOL of example sets. `_build_prompt()` picks
# one set deterministically per (body_id, local_id) so the same feature
# always gets the same prompt but neighbouring features get different
# prompts. The pools emphasise grounded / first-person / prosaic names
# with the occasional classical one — matching how real settlers on
# frontier worlds actually named places.
#
# Preamble wording matters too: "Settlers name …" reminds the model that
# these are human-chosen names, not fantasy coinages. The negative
# constraint "Most names are mundane" reinforces the grounded bias.
# Each pool entry is a list of `(style_label, example_name)` pairs. The
# style labels are cross-corridor — they teach Gemma the pattern, not
# a specific corridor's vocabulary. The target corridor's inflection
# gets substituted at the END of the prompt.
