Only points spent?

That is correct. Users may retain up to two of each type of point as reserve. Points beyond that margin are lost at a rate of 1 per hour.

...Ah.  Is that gradual, or a countdown clock?

The first point of each type is lost at the one hour mark subsequent point loss is continuous.

Very well, then.

...Is there some sort of abeyance in the event of, for example, being in continuous combat for the hour's duration?

Anyway.  That's not immediately relevant.

What is immediately relevant is her build.

She'll save the universal points, for now, and...

Preview: P[Nerve conduction speed] P[Precision of motion] M[Deductive reasoning] M[Reaction delay reduction] A[Biokinesis] A[Magic Item Crafting]

One point in nerve conduction speed: Resulting speed of 500 meters per second, approximately 10x human baseline.
One point in precision of motion: Allows for fine motor control down to about 1 millimeter precision without focus, 10 micrometers with focus. Gross motor control down to one hundred millimeters without focus and 1 millimeter with focus.

One point in deductive reasoning: Improvements to associative memory (0.3 points) minor increases to ease of recalling relevant information and marginally reduces likelihood of recalling irrelevant information when focusing. Double working memory capacity (0.4 points) Improves ability to evaluate probabilities brain can naturally assign five confidence levels without focus (0.3 points)
One point in Reaction delay reduction: Reduces reaction time to .01 seconds.

Note: magical abilities will not be usable until spending to create a mana pool a mana regeneration rate above zero.
One point in biokinesis: Unlocks spellcrafting interface (0.1 points), adds biokinetic components to spellcrafting interface (0.5 points), creates example healing spell (0.1 point), adds a basic sense of biology to a precision of one cubic centimeter that consumes 1 mana point per minute (0.3 points)

Note: Permanent magic items may also be created by spending points
One point in Magic item crafting: Unlocks spellcrafting interface (0.1 points), adds imbue component into spellcrafting interface (0.3 points), allows charging magical items with mana (0.3 points), adds durability increase components into spellcrafting interface (0.1 points), adds light creation components into spellcrafting interface (0.1 points), adds force creation components into spellcrafting interface (0.1 points)

Hmmm.

Spellcrafting interface?

Spellcrafting interface allow combining unlocked components to create spells. Spells may be assigned custom triggers for easy access. Some on the fly modification of spells is possible without the full interface. 0.1 magic points required to unlock interface and basic control structure components

Mmhmm.  Sounds useful.

What's this about having to create a mana pool and mana regeneration, anyway?

Mana capacity can be purchased at 1000 capacity per point.

Mana regeneration can be purchased at 0.1 mana per second per point.

Would she be able to create spell components or otherwise add them to the interface without necessarily purchasing them with points, if she knew any?

How much mana would that example force spell cost her?

New components can be created out of available components. Note: Some system defaults are tied into general system processes and are therefore more efficient than manually crafted components of equivalent effect.

Described force spell imparts 1000 joules of kinetic energy to target. Mana to force conversion ratio is 1 mana to 8 joules. Standard projectile spell envelope is 10 mana. Total spell cost 135 mana.

...Is there a limited set of spell components like that?

Hm.  Okay.

There is a finite set of atomic spell components, in total there are roughly five hundred thousand. Most such components are unlikely to be relevant to any given user.

...The set of spell component tied to/benefitting from interacting with system functions, she means?

Affirmative

...Well, she'll cross that bridge when she gets to it.

...Returning to the earlier subject, if she was able to, for example, observe the workings of a magic item, would she be able to then put the components into her spellcrafting interface without expending points?

There is a component which allows for copying observed components and integrating them into the spell crafting interface assuming you have all relevant permissions to invoke them. It requires magical analysis capabilities as a prerequisite.

...She'll get to that later, then.

She turns her power's analytic side on 'herself', full-blast, and then...

She's going to buy both the physical and mental components she previewed; she'll leave the arcane components til later.

The feeling her power returns for her effort feels like a shrug. It doesn't seem like there's anything broken in her from her power's perspective.

The world seems to slow a touch, her body seems paradoxically slower to respond as well. She is also suddenly extremely aware of the position of her body, she can feel each finger each toe how her legs are oriented how straight she's standing.

A thought pops into her mind unprompted... walls usually exist for a reason... why is there a wall there?

Yes, nothing's wrong, but she does want to see the system at work and that's something that's broken-ish.

She's been meaning to get on the other side of that wall for a while now, but it's hard to think and walk, when you're really thinking.

Still, armed with the barest basics, she supposes now is a good enough time to -

augh this damnable slowness.

Well, that's her own darn fault.  She'll just have to hunt monsters about it --

Oh, wow, that's a scary incentive structure.

Still, she probably ought to do something about this situation's...Thisness.

So, as she takes a second per few seconds(subjective) to handle walking and environment awareness, she continues peppering the system with queries.

Is there an off button for enhancements?

Preview: U[Selective time dilation]

Preview: A[Selective time dilation]

System enhancements are typically alterations to underlying biology and therefore cannot be toggled. Some enhancements such as defensive auras or active magical effects can be toggled if desired.

Time manipulation is not a supported function.

...hmm.
