"""
The Kintsugi Garden
A symbolic mirror for dreams, journals, and inner transitions.

A small-model symbolic reflection app built for the Build Small Hackathon.

This is NOT therapy, diagnosis, prediction, fortune-telling, or advice.
It is a symbolic reflection tool.

The design philosophy is "small model, strong scaffolding": rather than
relying on the LLM alone, the app surrounds a lightweight instruction model
(microsoft/Phi-4-mini-instruct) with deterministic Python:

  * a curated symbolic lexicon
  * keyword / symbol extraction with aliases and simple plurals
  * a session-local "Soul Map" memory
  * prompt compression (only the current entry + extracted symbols are sent)
  * structured, parsed output
  * deterministic mandala generation with PIL (no image model required)

    "user sovereign. Do not tell the user what to do. Never use "
    "prescriptive phrases like 'you should', 'you need to', 'begin the "
    "work of', or 'seek support / help / therapy'. Never speak with "
    "spiritual authority ('the gods reveal', 'spirit is telling you'), "
    "never predict the future, and never diagnose. If the user's entry is "
    "mundane (errands, routine, ordinary tasks), reflect that honestly — "

# Hand-curated to preserve the lexicon's contemplative register — formal
# but not clinical, archetypal but not academic, natural but not slangy.
# Single-word entries only (the tokenizer uses re.findall(r"[a-z]+")).
# Each alias maps to exactly one canonical symbol; for words that could
# resonate with multiple, the more direct mapping wins. Raven, owl, wolf,
# and dove are intentionally NOT aliased — their distinct Jungian
# resonances would be flattened if mapped to bird/dog; the LLM handles

## Mirror
3-6 sentences. Hedged language only ("may suggest", "could reflect",

future, diagnose, or speak with spiritual authority. When the supplied
symbols list is empty, leave this section to the deterministic
post-pass — do not invent psychological framing for routine entries
("a need to attune to inner rhythms", "external obligations without
a clear inner compass" — these are exactly the over-reaches to avoid).

## Key Symbols
List ONLY the symbols supplied above under "Detected symbols". Do NOT
invent new symbols, do NOT add symbols the user merely mentioned in
passing (e.g. "blue cup", "desk", "lunch") unless they are in the
supplied list. If the supplied list is "(no symbols from the lexicon
were detected)", write a single line: "No curated lexicon symbols were
detected." and nothing else under this heading.
For each supplied symbol, use this format:
- Symbol:
  - Possible meaning:
  - How it appears in the entry:

## Archetypal Themes
List themes that follow from the supplied symbols only. Do NOT invent
themes like "The Neutral Object" or "The Ordinary Man" for mundane
entries. When the supplied symbols list is non-empty, derive themes
from it; when empty, leave this section to the deterministic post-pass
(it will insert a neutral line) — do not attempt to fill it yourself.
- Theme:
  - Possible expression:

## Shadow Pattern
A cautious reflection on what may be avoided, projected, feared, or
over-identified with, drawn from the supplied symbols. Frame as
possibility, not verdict. Never use phrases like "you should", "you
need to", "begin the work of", or "seek support". When the supplied
symbols list is empty, leave this section to the deterministic
post-pass — do not invent shadow content from the entry text alone.

## Individuation Signal
What movement toward wholeness or self-knowledge may be present, drawn
from the supplied symbols. Hedged language only. Avoid grand archetypal
claims ("return to the Self", "the gods reveal") when the entry is
mundane (errands, routine, ordinary tasks). When the supplied symbols
list is empty, leave this section to the deterministic post-pass — do
not invent individuation content from the entry text alone.

    onto the GPU. duration=60 keeps ZeroGPU quota usage tight — Qwen3-8B
    Q4_K_M inference takes 1-3s, so 60s gives plenty of margin while
    keeping per-call quota cost at 120s (the spaces library tacks on
    ~60s of attach/release overhead, so the request is duration+60).
    On non-Spaces environments (local dev) the @spaces.GPU decorator is
    a no-op shim and llama.cpp runs CPU-only via Metal on macOS or CPU
    on Linux.
