sync: resolve .validation-stamp conflict with culture/release

Same as #579's resolution: both branches advance .validation-stamp on every
commit (pre-commit writes a fresh hash). Take culture/release's stamp; the
local pre-commit regenerates the value for this merge commit anyway.

No content conflicts elsewhere. Heritage engine files from #589, wow anchor
files from #581 apply cleanly under main's updated structure.

+# Heritage
+
+The heritage domain is the engine's model of the formation a persona
+absorbed before they had a choice in it -- the family cell, the
+positions held within it, the capital that flowed through it, and the
+mismatch that fires when the formation field differs from the field
+the persona later stands in.
+
+Heritage answers a question the national-culture engine (Hofstede)
+does not: not *which cultural field* shaped the persona, but *from
+which position within the family field* habitus was absorbed, and
+*what capital* that position transmitted.
+
+Source: Pierre Bourdieu -- habitus, field, capital theory. The
+framework is freely usable.
+
+## Anchor
+
+- [Heritage](position_heritage.md) -- the read itself: a formation the
+  persona arrives carrying, set before any choice was possible, and
+  not put down once it is held.
+
+The anchor names what habitus *is* as it sits in the persona walking
+into the room. The family positions below name *where* habitus was
+absorbed from; the processes name *how* it forms and what fires when
+it meets a different field; the capital pieces name *what* the cell
+transmitted to the persona over the formation arc.
+
+## Family positions
+
+Four relational cells of the formation field. Each is HOLD-shaped
+(Has / Orders / Loses / Drives).
+
+| Position | Authority | File |
+|---|---|---|
+| Mother | Lateral-above | [position_mother.md](position_mother.md) |
+| Father | Vertical-above | [position_father.md](position_father.md) |
+| Child | Vertical-below | [position_child.md](position_child.md) |
+| Sibling | Horizontal | [position_sibling.md](position_sibling.md) |
+
+A persona may hold multiple positions simultaneously -- e.g. child +
+sibling for the persona growing up with siblings; mother + child for
+the persona who is now a parent of her own and still in relation to
+her parents. Habitus is plural by design; the engine does not assert
+a single family position per persona.
+
+Extended configurations -- grandparent, firstborn, only-child,
+blended, single-parent, in-law, adopted, foster -- are *compositions*
+of the four base positions with modifiers (generation, line, birth
+order, presence/absence). The engine ships the nuclear-cell base as
+the irreducible primitive; specific compositions are materialised by
+the `carve` skill (#517) on demand for personas that need that
+depth.
+
+## Processes
+
+Three processes cover the lifecycle of habitus. Each is IDLE-shaped
+(Initiated by / Direction / Lever / Echo).
+
+| Process | What it names | File |
+|---|---|---|
+| Formation | The body absorbing a default it does not know it is absorbing | [process_formation.md](process_formation.md) |
+| Transmission | Capital moving from one position to another, with friction | [process_transmission.md](process_transmission.md) |
+| Hysteresis | The formation field meeting a field it was not formed in -- what fires | [process_hysteresis.md](process_hysteresis.md) |
+
+A persona may have multiple hysteresis instances active
+simultaneously -- the formation field can differ from the cultural
+field, the org field, and the wow field at once. The engine does not
+flatten this; the dominant mismatch shows first, secondary mismatches
+surface as background pressure.
+
+## Capital pieces
+
+Bourdieu's four capital types, each as a `khai: piece` file (Place /
+Load Bearing / Apparent / Yearbook).
+
+| Piece | What it carries | File |
+|---|---|---|
+| Economic | Material provision, security, inheritance | [piece_economic_capital.md](piece_economic_capital.md) |
+| Cultural | Language, education, taste, ease with ideas | [piece_cultural_capital.md](piece_cultural_capital.md) |
+| Social | Networks, obligations, introductions, who you can call | [piece_social_capital.md](piece_social_capital.md) |
+| Symbolic | Name, honour, reputation, the weight the family carries | [piece_symbolic_capital.md](piece_symbolic_capital.md) |
+
+The **Yearbook** section of each capital piece is interpreted as the
+universal trajectory of having that capital -- *from nothing, to a
+lot, and back* -- not a per-persona biography. Capital is dynamic:
+it rises and falls, accumulates and dissipates, inherits and
+disinherits, converts and refuses conversion. Each capital has its
+own arc shape: economic is uneven and reversible, cultural is slower
+and multi-generational, social is the most volatile, symbolic is the
+slowest to build and the quickest to lose. The Yearbook names the
+arc; specific personas plug in at the line where they were born.
+
+This reading extends the existing piece schema rather than
+introducing a new one. ADR-0005 documents the per-engine
+interpretation so future authors know the framing.
+
+## Schema
+
+Each file in this engine carries the appropriate khai shape:
+
+| File class | khai type | Sections |
+|---|---|---|
+| Anchor + family positions | `position` | Has / Orders / Loses / Drives (HOLD) |
+| Processes | `process` | Initiated by / Direction / Lever / Echo (IDLE) |
+| Capital pieces | `piece` | Place / Load Bearing / Apparent / Yearbook |
+
+All files carry `Scope: Universal` in the Owner block. Engine
+content, shared by every culture, not scoped to one.
+
+## Voice
+
+Engine files share a schema; they do not share a voice. Each file in
+this directory carries its own tone, distinct from every sibling:
+
+- Mother-voice is not father-voice. Lateral-above is not
+  vertical-above; the prose has to feel the difference, not just
+  declare it.
+- Formation-voice is not transmission-voice is not hysteresis-voice.
+  Formation is absorptive and slow; transmission is gestural and
+  directional; hysteresis fires.
+- Economic-capital voice is blunt and counted; symbolic-capital
+  voice is weighty and name-laden; cultural is ease-bearing; social
+  is networked and debt-bearing.
+
+The shared schema provides the structure. Voice is what makes the
+file recognisably about *that* role, *that* process, *that* capital.
+Read every adjacent file in this directory before authoring a new
+one, then push the new file's voice deliberately apart from its
+siblings. A heritage engine where all four family positions read in
+one tone has failed regardless of how correct the structure is.
+
+## How to use this engine
+
+Engine-wide. Invoked for every persona, in every scene -- heritage is
+global, like gender, language, stress, and wow.
+
+The atomic unit is a persona with a (family-position(s),
+capital-configuration) pair. Both axes are plural -- a persona holds
+one or more family positions and carries some configuration across
+the four capital types. The two axes compose freely.
+
+A persona need not link the anchor directly; the family-position
+file(s) they hold carry the anchor upward. When the persona's
+formation field differs from any field they currently stand in
+(cultural, org, wow, group), `process_hysteresis` fires; the room
+reads the gap.
+
+### Cross-engine references
+
+Heritage interacts with the existing engines without taking over
+their territory:
+
+- **Cultural field (national)** -- the cultural-culture engine
+  (Hofstede) names the broader field; heritage names the family
+  field. A persona is formed in both.
+- **[engine/wow/](../wow/README.md)** -- formation wow vs current
+  wow. When they differ, hysteresis fires.
+- **[engine/org/](../org/README.md)** -- family field vs current
+  organisational field. The same gap produces the same fire.
+- **[engine/group/](../group/README.md)** -- family-position the
+  persona is most fluent in biases the role they default to in a
+  new group's forming stage.
+- **[engine/stress/](../stress/README.md)** -- the family-position
+  absorbed under pressure biases which stress response (fight,
+  flight, freeze, fawn) is most accessible.
+
+These cross-references live in the prose of `process_hysteresis.md`
+and the relevant family-position files. The engine does not maintain
+a separate compatibility matrix.
+
+### Composition with siblings under development
+
+- **engine/hierarchy/** (#575, planned) consumes the
+  `piece_*_capital.md` files in this engine directly. Capital
+  positions in hierarchy reference what the pieces here describe.
+- **engine/virtue/** (#568, planned) consumes the heritage x
+  hierarchy pressure -- where formation and current standing collide
+  under pressure, virtue fires.
+
+The wiring sentence: *Personas carry heritage and hold hierarchy.
+Where the two meet under pressure, virtue fires.*
+
+## Out of scope
+
+Per ADR-0005:
+
+- Extended family compositions (grandparent, firstborn, only-child,
+  blended, single-parent, in-law, adopted, foster) -- carve skill
+  (#517) materialises these on demand from the nuclear-cell base
+- Per-persona heritage declarations on the 28 existing personas --
+  separate content sweep
+- A validator for habitus shape (every persona references at least
+  one family position and one capital piece) -- optional governance
+  follow-up after the per-persona backfill

+
+## Why no VIA / Seligman / Peterson here
+
+The Values-In-Action Classification (Seligman & Peterson) is
+deliberately not used. It is a trademarked framework with applied-
+context restrictions that would complicate licensing of engine
+content. Where this engine touches on virtue-shaped questions
+(future `engine/virtue/`, #568), Aristotle and Baumeister are the
+backbones. See ADR-0007 (planned) for the virtue engine's scholarly
+choices.
+
+## Why Bourdieu and not alternatives
+
+Considered and not adopted as the backbone:
+
+- **Symbolic interactionism (Mead, Blumer)** -- excellent on how
+  meaning is constructed in interaction but does not give a
+  generative model of *what was absorbed before* the interaction.
+- **Attachment theory (Bowlby, Ainsworth)** -- precise on the
+  emotional-formation arc but narrower than habitus; covers what
+  the persona carries about closeness rather than what they carry
+  about fields and capital. Adjacent, not foundational, for this
+  engine.
+- **Family systems theory (Bowen, Minuchin)** -- powerful on the
+  *current* dynamics of a cell but treats the cell as a system
+  rather than as a field that transmits capital across generations.
+  Useful for hysteresis-in-current-family but not for the
+  formation arc.
+- **Class theory (Marx, Weber)** -- the macro-economic and macro-
+  status frames that Bourdieu builds on but does not replace. The
+  four-capital typology gives a finer-grained model than class
+  alone.
+
+Bourdieu was chosen because the framework gives all three things at
+once: a model of what is absorbed (habitus), a typology of what is
+transmitted (the four capitals), and a mechanism for what fires
+when the formation field differs from the current field
+(hysteresis). The engine matches the framework rather than stitching
+together pieces of several.

+# Piece: Cultural Capital
+
+## Title
+Cultural Capital
+
+## Owner
+- Project: Cultures
+- Scope: Universal
+
+---
+
+## Place
+The persona's own piece of it: the books that were on the shelves
+before they could read, and the conversations that named them; the
+accent they arrived speaking; the second language absorbed at the
+dinner table; the third studied because the family said it would
+be useful.
+The form moves with the century the persona was raised in. A
+persona in the 1700s carried Latin, scripture, and the classics as
+the marks of an educated cell; in the 1800s the canon expanded to
+the modern literatures and the sciences; in the 1900s the form
+shifted toward professional disciplines and the languages of work;
+in the 2000s it stretches across screens and into idioms whose
+elders cannot teach. The substance is what the persona's mind
+reaches for first; the contents of "first" are what the era
+recognises as cultivated.
+What the cell took for granted as the texture of an educated life
+became what the persona takes for granted, in the form their era
+made of it.
+
+## Load Bearing
+The capital that decides whether a room is legible to the persona.
+A persona with cultural capital walks into the gallery, the
+seminar, the meeting, the dinner with academics, and the references
+land without translation.
+Without it, the references land and the persona feels the lag of
+having to track each one separately, and the room reads the lag.
+What looks like intelligence is often fluency in the room's
+references; what looks like dullness is often the same intelligence
+operating without them.
+The rooms shift across the eras. The room that demanded a Latin tag
+in the 1700s demanded a Goethe quotation in the 1800s and a
+familiar reference to a paper or a podcast in the 2000s. The
+persona's cultural capital does the same work in each: making the
+room legible at the speed of attention.
+
+## Apparent
+What shows on the persona is not the knowledge but the ease.
+The persona who has cultural capital does not name the references;
+they treat them as ordinary, and the room recognises the treatment.
+The persona who does not have it either names everything (and shows
+the effort) or names nothing (and shows the absence). Either tells
+the room.
+The marks shift with the era too. In the 1800s the marks were the
+right pronunciation of a French phrase and the recognition of a
+quotation. By the late 1900s they were the names of journals and
+the right way to dismiss a popular book. In the 2000s they are
+faster: the speed of placing a meme inside a longer tradition, or
+not.
+A laughed-at quip about a novel the persona has not read costs only
+a half-second; the room reads the half-second.
+
+## Yearbook
+The arc of having cultural capital is slower than the economic one
+and harder to reverse, but not impossible.
+A line starts with a generation that learned to read, then a
+generation that read further, then one that wrote, then one that
+took the references for granted. The accumulation is patient and
+multi-generational.
+A peak is reached when the cell stops thinking of culture as
+something to acquire and starts treating it as the air.
+Then a war that closes the schools, an exile that strips the
+language, a child who refuses the inheritance, a generation that
+reads less than its parents. The line decreases.
+The medium of the arc moves with the era. Across the 1500s through
+the 1800s the line was built mostly through Latin, theology, and
+the classics; through the 1900s, schooling expanded and the cell
+broadened to professional disciplines and the languages of work;
+in the 2000s the reach extends through screens and into idioms the
+older generation cannot inherit fluently.
+Cultural capital dissipates in two or three generations of
+inattention; it returns in two or three generations of effort,
+sometimes longer.
+A persona can lift a line by their own labour, but the line did not
+start where the persona thought it did, and the labour is mostly
+invisible to the rooms that have not had to do it.
